Sleep divorce: could sleeping separately from your partner lead to a better night’s rest?

<div class="theconversation-article-body"> Hundreds of years ago, it was common for married couples among the European upper classes to have separate bedrooms. Sleeping separately was a <a href="https://www.bedstar.co.uk/sleep-talk/queens-and-kings-separate-beds.html">symbol of luxury and status</a> historically reserved for royalty and the very wealthy. Nowadays, it’s common for married couples and other couples in relationships to sleep in the same bed. But sometimes – for reasons from conflicting schedules to snoring to sleep talking – couples might choose to sleep separately in pursuit of a better night’s sleep. This is known as “sleep divorce”. Though I prefer the term “sleep separation”, as this doesn’t have to be a permanent arrangement – but more on that later. So why might couples choose to sleep separately? And what does the evidence say about the effects on sleep quality if you sleep alone versus with a partner? <h2>Why do couples opt for a sleep separation?</h2> Couples may choose to sleep apart if one partner’s sleep is disturbing the other’s, or both are disrupting one another. This can happen for a variety of reasons. These include waking up frequently in the night, mismatched body clocks (for example, one person coming to bed later than the other), conflicting schedules (for example, shift workers), snoring, twitching legs or sleep talking. Parents with babies and young children may choose to sleep separately to avoid both partners’ sleep being disturbed. Those with conflicting preferences for sleeping environments, such as one partner liking a cool room with a fan and the other preferring warmth, may also decide to sleep apart. <h2>What are the benefits of sleeping alone?</h2> Many couples <a href="https://pubmed.ncbi.nlm.nih.gov/22609123/">say they prefer</a> to sleep – and sleep better – next to their partner. But when scientists measure sleep objectively, such as via an electroencephalogram (EEG) to assess brain waves, the data actually shows <a href="https://pubmed.ncbi.nlm.nih.gov/22609123/">poorer sleep quality</a> when co-sleeping. So sleeping alone may, in fact, mean better quality and longer sleep. Research also shows when one member of the couple has a sleep disorder, such as insomnia or <a href="https://www.healthdirect.gov.au/obstructive-sleep-apnoea">sleep apnoea</a> (where breathing is frequently interrupted during sleep), these people often inadvertently <a href="https://pubmed.ncbi.nlm.nih.gov/10818830/">wake up their partner</a> <a href="https://pubmed.ncbi.nlm.nih.gov/31553049/">when they wake</a> in the night. So sleeping alone could be a good idea if your bed partner has a sleep disorder. What’s more, <a href="https://journals.sagepub.com/doi/abs/10.1177/02654075231193449">studies have found</a> <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC2644899/">sleep disturbances</a> are linked to <a href="https://pubmed.ncbi.nlm.nih.gov/15164910/">reduced relationship satisfaction</a>. So sleeping apart could actually mean happier couples. Finally, anyone who has struggled with their sleep will know anxiety around sleep is common. Many clients I have seen who experience insomnia report sleeping alone can alleviate some of their anxiety because at least they know they won’t disturb, or be disturbed by, their partner. <h2>Are there any downsides to separate sleeping arrangements?</h2> Some people dislike sleeping alone, reporting comfort, and feelings of safety and protection when sleeping alongside their partner – and loneliness when they don’t. Sleeping separately also requires two rooms, or at least two beds. Many couples may not have these options available to them in their home. Sleeping separately is <a href="https://www.abc.net.au/news/2023-06-22/couples-on-why-they-love-sleeping-separately/102448812">often stigmatised</a>, with some people seeing it as the death of a couple’s sex life. But while sleeping in separate beds may provide fewer opportunities for sex, this doesn’t necessarily mean the end of intimacy. Sleeping apart could mean some couples actually have more sex. We know better sleep is linked to more <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC2644899/">positive feelings about relationships</a>, so it’s possible the desire to be intimate could increase after a good night’s sleep in separate beds. Sleeping apart may even mean some couples have more energy to be intimate. Nonetheless, if you choose to sleep separately from your partner, it’s important to have an open discussion and prioritise opportunities for connection and intimacy. One client I worked with referred to “visiting rights” where her partner came into her bed for a short period before sleep or in the morning. <h2>Who should potentially consider a sleep separation?</h2> You may wish to think about a “sleep separation” if you are disturbing each other’s sleep, have young children, or have different preferences in terms of temperature, light and noise, which are causing issues. Ultimately, if sleeping in the same bed is leading to poor sleep then sleeping apart, if it’s possible, could help. If you can’t sleep separately there may be other ways to reduce disturbance from a partner such as using an eye mask, white noise or earplugs. If you decide to try a sleep separation, remember this can be a flexible arrangement or “re-set” and doesn’t have to be permanent, or every night. Some couples find sleeping separately during the working week but sharing a bed on the weekend works well for them. Lastly, it’s important to talk to your GP about any persistent sleep problems, such as snoring, insomnia, or unusual behaviour during sleep (for example, shouting or walking around), as there may be an underlying sleep disorder which needs treating.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/258085/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> By <a href="https://theconversation.com/profiles/alix-mellor-2406858">Alix Mellor</a>, Research Fellow, Psychology, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How sleep loss can lead to weight gain – and worse

<div class="theconversation-article-body"> You stayed up too late scrolling through your phone, answering emails or watching just one more episode. The next morning, you feel groggy and irritable. That sugary pastry or greasy breakfast sandwich suddenly looks more appealing than your usual yogurt and berries. By the afternoon, chips or candy from the break room call your name. This isn’t just about willpower. Your brain, short on rest, is nudging you toward quick, high-calorie fixes. There is a reason why this cycle repeats itself so predictably. Research shows that <a href="https://doi.org/10.1038/s41574-022-00747-7">insufficient sleep disrupts hunger signals</a>, <a href="https://doi.org/10.1016/j.smrv.2021.101514">weakens self-control</a>, <a href="https://doi.org/10.1016/j.metabol.2018.02.010">impairs glucose metabolism</a> and <a href="https://doi.org/10.1002/oby.23539">increases your risk of weight gain</a>. These changes <a href="https://doi.org/10.1523/JNEUROSCI.0250-18.2018">can occur rapidly</a>, even after a single night of poor sleep, and <a href="https://doi.org/10.1111/nyas.14926">can become more harmful over time</a> if left unaddressed. I am a <a href="https://scholar.google.com/citations?user=sTqquL0AAAAJ&hl=en">neurologist specializing in sleep science</a> and its impact on health. Sleep deprivation affects millions. According to the Centers for Disease Control and Prevention, more than one-third of U.S. adults <a href="https://www.cdc.gov/sleep/data-research/facts-stats/adults-sleep-facts-and-stats.html">regularly get less than seven hours of sleep</a> per night. Nearly three-quarters of adolescents <a href="https://www.cdc.gov/sleep/data-research/facts-stats/high-school-students-sleep-facts-and-stats.html?utm_source=chatgpt.com">fall short of the recommended 8-10 hours sleep</a> during the school week. While anyone can suffer from sleep loss, essential workers and first responders, including nurses, firefighters and emergency personnel, are <a href="https://doi.org/10.1136/bmj.i5210">especially vulnerable</a> <a href="https://doi.org/10.3390/jcm13154505">due to night shifts and rotating schedules</a>. These patterns disrupt the body’s internal clock and are linked to increased cravings, poor eating habits and elevated risks for obesity and metabolic disease. Fortunately, even a few nights of consistent, high-quality sleep can help rebalance key systems and start to reverse some of these effects. <h2>How sleep deficits disrupt hunger hormones</h2> Your body regulates hunger through a <a href="https://doi.org/10.1056/NEJMra2402679">hormonal feedback loop</a> <a href="https://doi.org/10.1016/j.peptides.2025.171367">involving two key hormones</a>. Ghrelin, produced primarily in the stomach, signals that you are hungry, while leptin, which is produced in the fat cells, tells your brain that you are full. Even one night of restricted sleep <a href="https://doi.org/10.1002/oby.23616">increases the release of ghrelin and decreases leptin</a>, which leads to greater hunger and reduced satisfaction after eating. This shift is driven by changes in how the <a href="https://doi.org/10.1002/oby.23616">body regulates hunger</a> and stress. Your brain becomes less responsive to fullness signals, while at the same time <a href="https://doi.org/10.1111/obr.13051">ramping up stress hormones</a> that can increase cravings and appetite. These changes are not subtle. In controlled lab studies, healthy adults reported <a href="https://doi.org/10.1111/j.1365-2869.2008.00662.x">increased hunger and stronger cravings</a> for calorie-dense foods after sleeping only four to five hours. The effect worsens with ongoing sleep deficits, which can lead to a <a href="https://doi.org/10.1111/obr.13051">chronically elevated appetite</a>. <figure><iframe src="https://www.youtube.com/embed/r6pItuOoGxc?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>Sleep is as important as diet and exercise in maintaining a healthy weight.</figcaption></figure> <h2>Why the brain shifts into reward mode</h2> Sleep loss changes how your brain evaluates food. Imaging studies show that <a href="https://doi.org/10.1038/ncomms3259">after just one night of sleep deprivation</a>, the prefrontal cortex, which is responsible for decision-making and impulse control, <a href="https://doi.org/10.3945/ajcn.111.027383">has reduced activity</a>. At the same time, <a href="https://doi.org/10.1523/JNEUROSCI.0250-18.2018">reward-related areas such as the amygdala</a> and the nucleus accumbens, a part of the brain that drives motivation and reward-seeking, become <a href="https://doi.org/10.1093/sleep/zsx125">more reactive to tempting food cues</a>. In simple terms, your brain becomes more tempted by junk food and less capable of resisting it. Participants in sleep deprivation studies not only rated high-calorie foods as more desirable but were also <a href="https://doi.org/10.3945/ajcn.111.027383">more likely to choose them</a>, regardless of how hungry they actually felt. <h2>Your metabolism slows, leading to increased fat storage</h2> Sleep is also critical for blood sugar control. When you’re well rested, your body efficiently uses insulin to move sugar out of your bloodstream and into your cells for energy. But even one night of partial sleep can <a href="https://doi.org/10.1210/jc.2009-2430">reduce insulin sensitivity by up to 25%</a>, leaving more sugar circulating in your blood. If your body can’t process sugar effectively, it’s more likely to convert it into fat. This contributes to weight gain, especially around the abdomen. Over time, poor sleep is associated with <a href="https://doi.org/10.1161/CIR.0000000000000444">higher risk for Type 2 diabetes and metabolic syndrome</a>, a <a href="https://www.mayoclinic.org/diseases-conditions/metabolic-syndrome/symptoms-causes/syc-20351916">group of health issues</a> such as high blood pressure, belly fat and high blood sugar that raise the risk for heart disease and diabetes. On top of this, sleep loss raises cortisol, your body’s main stress hormone. <a href="https://doi.org/10.1210/jc.2013-4254">Elevated cortisol encourages fat storage</a>, especially in the abdominal region, and can further disrupt appetite regulation. <h2>Sleep is your metabolic reset button</h2> In a culture that glorifies hustle and late nights, sleep is often treated as optional. But your body doesn’t see it that way. Sleep is not downtime. It is active, essential repair. It is when your brain recalibrates hunger and reward signals, your hormones reset and your metabolism stabilises. Just one or two nights of quality sleep can begin to <a href="https://doi.org/10.1152/ajpendo.00301.2013">undo the damage from prior sleep loss</a> and restore your body’s natural balance. So the next time you find yourself reaching for junk food after a short night, recognize that your biology is not failing you. It is reacting to stress and fatigue. The most effective way to restore balance isn’t a crash diet or caffeine. It’s sleep. Sleep is not a luxury. It is your most powerful tool for appetite control, energy regulation and long-term health.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/255726/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/joanna-fong-isariyawongse-1470879">Joanna Fong-Isariyawongse</a>, Associate Professor of Neurology, <a href="https://theconversation.com/institutions/university-of-pittsburgh-854">University of Pittsburgh</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Scientists unpack the latest trend for getting better sleep

<div class="theconversation-article-body"> If you’ve been on social media lately – perhaps scrolling in the middle of the night, when you know you shouldn’t but you just can’t sleep – you might have seen those videos promoting a get-to-sleep technique called “cognitive shuffling”. The idea, proponents say, is to engage your mind with random ideas and images via a special formula: <ol> <li>pick a random word (such as “cake”)</li> <li>focus on the first letter of the word (in this case, C) and list a bunch of words starting with that letter: cat, carrot, calendar and so on</li> <li>visualise each word as you go along</li> <li>when you feel ready, move onto the next letter (A) and repeat the process</li> <li>continue with each letter of the original word (so, in this case, K and then E) until you feel ready to switch to a new word or until you drift off to sleep.</li> </ol> It’s popular on Instagram and TikTok, but does “cognitive shuffling” have any basis in science? <h2>Where did this idea come from?</h2> The cognitive shuffling technique was made famous by Canada-based researcher Luc P. Beaudoin more than a decade ago, when he published a <a href="https://summit.sfu.ca/item/12143">paper</a> about how what he called “serial diverse imagining” could help with sleep. One of Beaudoin’s hypothetical <a href="https://summit.sfu.ca/item/12143">examples</a> involved a woman thinking of the word “blanket”, then thinking bicycle (and imagining a bicycle), buying (imagining buying shoes), banana (visualising a banana tree) and so on. Soon, Beaudoin <a href="https://summit.sfu.ca/item/12143">writes</a>, she moves onto the letter L, thinking about her friend Larry, the word “like” (imagining her son hugging his dog). She soon transitions to the letter A, thinking of the word “Amsterdam”: <blockquote> and she might very vaguely imagine the large hand of a sailor gesturing for another order of fries in an Amsterdam pub while a rancid accordion plays in the background. </blockquote> Sleep soon ensues. The goal, <a href="https://summit.sfu.ca/item/17237">according to Beaudoin</a>, is to think briefly about: <blockquote> a neutral or pleasant target and frequently [switch] to unrelated targets (normally every 5-15 seconds). </blockquote> Don’t try to relate one word with another or find a link between the words; resist the mind’s natural tendency toward sense-making. While the research into this technique is still in its infancy, the idea is grounded in science. That’s because we know from <a href="https://pubmed.ncbi.nlm.nih.gov/31918338/">other research</a> good sleepers tend to have different kinds of thoughts in bed to bad sleepers. People with insomnia are <a href="https://www.sciencedirect.com/science/article/pii/S0005796799001369?casa_token=Ycf204NAkdYAAAAA:EIYBaXLXetofajJ46yu0AQXfGRAmLsWIwP0S1Dzkaj1_X8Q_2GWbSnpiuqVseJuJ-Znj3Mrl39s">more focused on worries</a>, problems, or noises in the environment, and are often preoccupied with not sleeping. Good sleepers, on the other hand, typically have <a href="https://www.sciencedirect.com/science/article/pii/S1053810098903336">dream-like, hallucinatory, less ordered thoughts</a> before nodding off. <h2>Sorting the pro-somnolent wheat from the insomnolent chaff</h2> Cognitive shuffling attempts to mimic the thinking patterns of good sleepers by simulating the dream-like and random thought patterns they generally have before drifting off to sleep. In particular, Beaudoin’s <a href="https://summit.sfu.ca/item/17237">research</a> describes two types of sleep-related thoughts: insomnolent (or anti-sleep) and pro-somnolent (sleep-promoting) thoughts. Insomnolent thoughts include things such as worrying, planning, rehearsing, and ruminating on perceived problems or failings. Pro-somnolent thoughts on the other hand involve thoughts that can help you fall asleep, such as dream-like imagery or having a calm, relaxed state of mind. Cognitive shuffling aims to distract from or interfere with insomnolent thought. It offers a calm, neutral path for your racing mind, and can reduce the stress associated with not sleeping. Cognitive shuffling also helps tell your brain you are ready for sleep. In fact, the process of “shuffling” between different thoughts is similar to the way your brain naturally drifts off to sleep. During the transition to sleep, <a href="https://www.sciencedirect.com/science/article/pii/S0987705324000121">brain activity</a> slows. Your brain starts to generate disconnected images and fleeting scenes, known as hypnagogic hallucinations, without a conscious effort to make sense of them. By mimicking these scattered, disconnected, and random thought patterns, cognitive shuffling may help you transition from wakefulness to sleep. And the preliminary research into this is promising. Beaudoin and his team have <a href="https://www.researchgate.net/publication/277325155_A_test_of_the_somnolent_mentation_theory_and_the_cognitive_shuffle_insomnia_treatment">found</a> <a href="https://www.researchgate.net/publication/300004607_Serial_Diverse_Imagining_Task_A_New_Remedy_for_Bedtime_Complaints_of_Worrying_and_Other_Sleep-Disruptive_Mental_Activity">serial diverse imagining</a> helps to lower arousal before sleep, improve sleep quality and reduce the effort involved in falling asleep. However, with only a small number of research studies, more work is needed here. <h2>It didn’t work. Now what?</h2> As with every new strategy, however, practise makes perfect. Don’t be disheartened if you don’t see an improvement straight away; these things take time. Stay consistent and be kind to yourself. And what works for some won’t work for others. Different people benefit from different types of strategies depending on how they relate to and experience stress or stressful thoughts. Other <a href="https://onlinelibrary.wiley.com/doi/pdf/10.1111/jsr.13763">strategies</a> to help create the right conditions for sleep include: <ul> <li>keeping a consistent pre-bedtime routine, so your brain can wind down</li> <li><a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6557693/?undefined&utm_medium=organic&utm_source=blog&utm_campaign=meditation-for-sleep">watching your thoughts, without judgement</a>, as you lie in bed</li> <li>writing down worries or <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC5758411/">to-do lists</a> earlier in the day so you don’t think about them at bedtime.</li> </ul> If, despite all your best efforts, night time thoughts continue to impact your sleep or overall wellbeing, consider seeking professional help from your doctor or a trained sleep specialist.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/256444/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> By <a href="https://theconversation.com/profiles/melinda-jackson-169319">Melinda Jackson</a>, Associate Professor at Turner Institute for Brain and Mental Health, School of Psychological Sciences, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> and <a href="https://theconversation.com/profiles/eleni-kavaliotis-2396793">Eleni Kavaliotis</a>, Research Fellow in the Sleep, Cognition, and Mood Laboratory at Monash University, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Weight loss drug approved to treat sleep apnoea

<div class="theconversation-article-body"> Last week, Australia’s <a href="https://www.ebs.tga.gov.au/ebs/picmi/picmirepository.nsf/pdf?OpenAgent&id=CP-2023-PI-02114-1&d=20250603172310101">Therapeutic Goods Administration</a> (TGA) approved <a href="https://www.afr.com/companies/healthcare-and-fitness/tga-approves-weight-loss-drug-to-treat-sleep-disorder-20250604-p5m4vq">the weight-loss drug Mounjaro</a> to treat sleep apnoea, a condition in which breathing stops and starts repeatedly during sleep. The TGA has indicated Mounjaro can be used to treat moderate to severe obstructive sleep apnoea in adults with obesity (a body-mass index of 30 or above). The <a href="https://www.fda.gov/news-events/press-announcements/fda-approves-first-medication-obstructive-sleep-apnea">United States Food and Drug Administration</a> approved the same drug for sleep apnoea last year. So how could this drug, most commonly used for weight management and conditions such as type 2 diabetes, help people with sleep apnoea? <h2>What is sleep apnoea?</h2> Obstructive sleep apnoea is a common sleep disorder affecting almost <a href="https://www.thelancet.com/journals/lanres/article/PIIS2213-2600(19)30198-5/abstract#:%7E:text=To%20our%20knowledge%2C%20this%20is,and%20to%20maximise%20cost%2Deffectiveness.">1 billion people</a> worldwide. It’s characterised by repeated closures of the airway during sleep (called “<a href="https://www.healthdirect.gov.au/obstructive-sleep-apnoea">apnoeas</a>”). These can be partial or complete closures, meaning breathing can become shallow or stop completely. As well as causing fragmented sleep, repeated collapse of the airway disrupts oxygen flow to the body. This strains the heart and contributes to an increased risk of <a href="https://www.sciencedirect.com/science/article/pii/S1875213620300413">cardiovascular and metabolic complications</a> <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC11172971/">such as</a> diabetes, high blood pressure and stroke. One of the key risk factors for obstructive sleep apnoea is obesity. About <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9130173/">80% of people</a> with the condition live with obesity. In fact, obesity and sleep apnoea share a <a href="https://www.sciencedirect.com/science/article/pii/S0939475325001681">bidirectional relationship</a>, with obesity increasing the risk of developing sleep apnoea, and vice versa. Obesity increases the risk of sleep apnoea by adding fat around the neck, which narrows the airway and impacts breathing during sleep. In turn, sleep apnoea can contribute to weight gain by disrupting hormones that regulate hunger (ghrelin) and fullness signals (leptin). Fatigue also contributes, making it harder to maintain a healthy weight and easier to gain weight over time, creating <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC5836788/">a vicious cycle</a> where each condition worsens the other. Weight loss is a key part of <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9059581/">treating sleep apnoea</a>. It helps reduce the severity of symptoms and also lowers the risk of heart disease and other health problems which may arise as a result of <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7874414/">sleep apnoea</a>. However, achieving and sustaining weight loss through lifestyle changes is often challenging. A continuous positive airway pressure (CPAP) machine is generally the <a href="https://www1.racgp.org.au/ajgp/2024/june/management-of-obstructive-sleep-apnoea-in-primary">first-line therapy</a> for managing moderate to severe sleep apnoea. It delivers a steady stream of pressurised air through a mask to keep the airway open during sleep, which stabilises breathing and improves sleep quality. Despite being an effective treatment, many people find the CPAP machine uncomfortable, unattractive or hard to use regularly. This can mean people don’t always <a href="https://pubmed.ncbi.nlm.nih.gov/30684472/">stick to it</a>. Given the significant human and <a href="https://pubmed.ncbi.nlm.nih.gov/34015136/">economic costs of sleep apnoea</a> it’s pertinent to keep exploring new prevention and management strategies. <h2>What is Mounjaro, and how could it help people with sleep apnoea?</h2> Mounjaro is the brand name of a drug called tirzepatide. Elsewhere, it goes by other brand names, such as Zepbound. Tirzepatide works by <a href="https://www.pnas.org/doi/full/10.1073/pnas.2116506119">mimicking two hormone receptors</a> in the gut, glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP). These <a href="https://www.sciencedirect.com/science/article/pii/S2212877818309001">two hormones</a> play a key role in regulating our appetite, food intake and blood sugar levels. GLP-1 and GIP are released naturally in the body when we eat, but by mimicking their effects, tirzepatide allows people to feel fuller with smaller meals. If a person is eating less overall, this can lead to weight loss. In <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa2404881">a study of 469 people</a> with obesity and moderate to severe obstructive sleep apnoea, one year of tirzepatide treatment was associated with up to a 60% reduction in sleep apnoea severity. This is compared to a 3% reduction in people receiving a placebo. In addition, evidence shows tirzepatide is associated with improvements in <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC11598664/pdf/nihms-2005020.pdf">several key health indicators</a>, including reduced systemic inflammation, <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC11972082/">enhanced insulin sensitivity</a> and lower blood pressure. Changes <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC10157777/">such as these</a> may improve respiratory function and help protect against cardiovascular and metabolic complications, which are common outcomes of untreated sleep apnoea. <h2>Are there any side effects?</h2> While Mounjaro could be helpful for people with sleep apnoea, gastrointestinal <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC10088547/pdf/jomes-32-1-25.pdf">side effects</a> are relatively common with this medication. These can include nausea, vomiting, diarrhoea, constipation and loss of appetite. These side effects typically go away as the person gets used to the medication. Some patients have also reported <a href="https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2790392">gallbladder problems</a>. Despite these concerns, there is an <a href="https://assets.cureus.com/uploads/review_article/pdf/343603/20250405-83416-dhs9d8.pdf">interest in Mounjaro as sleep apnoea treatment</a> as it provides the first pharmaceutical option for a condition that has traditionally relied on mechanical treatments such as CPAP machines. That said, it’s important to note Mounjaro is indicated for use in patients with obesity, and <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9130173/">not all patients</a> with sleep apnoea are overweight or obese. In some <a href="https://www.thelancet.com/journals/eclinm/article/PIIS2589-5370(25)00153-1/fulltext?rss=yes">people of a healthy weight</a>, narrow skeletal structure or upper airway anatomy, such as larger soft palates (which can reduce airway space and make it more prone to collapse during sleep), could contribute to obstructive sleep apnoea. For those patients, non-pharmacological treatment options such as mandibular advancement devices (oral appliances that move the lower jaw forward and keep the airway open) and upper airway surgery may be needed to effectively manage the condition. Mounjaro is given as a weekly injection. In Australia, Mounjaro is not currently subsidised under the Pharmaceutical Benefits Scheme and is available only by private prescription, with prices beginning at around <a href="https://cosmeticclinic.net.au/mounjaro-australia-cost/#:%7E:text=On%20average%2C%20the%20cost%20of%20Mounjaro%20in%20Australia,the%20frequency%20of%20use%20and%20the%20required%20dosage.">A$395 per month</a>. The significant out-of-pocket cost will limit access to Mounjaro for many patients. Mounjaro’s approval for the treatment of sleep apnoea may offer new hope for many people. But considering the diversity in patient presentations and limited data from large population studies, it’s too early to say whether this will transform sleep apnoea care in Australia.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/258195/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> By <a href="https://theconversation.com/profiles/yaqoot-fatima-2407464">Yaqoot Fatima</a>, Professor of Sleep Health, <a href="https://theconversation.com/institutions/university-of-the-sunshine-coast-1068">University of the Sunshine Coast</a> and <a href="https://theconversation.com/profiles/nisreen-aouira-2407465">Nisreen Aouira</a>, Research Program Manager, Thompson Institute, <a href="https://theconversation.com/institutions/university-of-the-sunshine-coast-1068">University of the Sunshine Coast</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Body

The surprising power of photography in ageing well

<div class="theconversation-article-body"> Older adults are often faced with lifestyle changes that can disrupt their sense of place and purpose. It may be the loss of a partner, downsizing their home, or moving to residential aged care. And these changes can come with loss of identity, uncertainty, disconnect and isolation. But what if I told you a simple camera could help alleviate some of these pains? I’ve been working with older adults for the past decade, using photography as a way of connecting with place, and the results have been transformational. <h2>The value of creative ageing</h2> <a href="https://www.frontiersin.org/journals/public-health/articles/10.3389/fpubh.2023.1288760/full">Research has shown</a> arts engagement can significantly enhance the mental wellbeing and overall health of older adults. Australia has responded by developing <a href="https://www.nsw.gov.au/arts-and-culture/engage-nsw-arts-and-culture/resource-hub/creative-ageing">Creative Ageing Frameworks</a> and the <a href="https://www.arts.qld.gov.au/images/documents/artsqld/Research/National-Arts-and-Health-Framework-May-2014.pdf">National Arts Health Framework</a>, which position creative activity as valuable components of productive and healthy ageing. But while creative ageing programs are expanding, there are still many barriers to participation, including cost, accessibility, participants’ self-doubt, and a lack of skilled facilitators. This highlights a need for more inclusive approaches that use familiar tools – and that’s where photography comes in. Photography is a multi-sensory embodied practice. It allows us to be mindful, slow down, and look for beauty in everyday life. It can also prompt us to see the world differently. Recent research by my colleagues and I documents how taking photographs can increase older adults’ <a href="https://doi.org/10.1111/ajag.70040">connection to place, creativity and overall wellbeing</a>. Specifically, we explored the impact of photography as not so much a structured “art activity”, but as a practice of connecting to place and other people through group photo walks. <figure><iframe src="https://player.vimeo.com/video/866929737" width="500" height="281" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> Over the past 18 months we’ve been working with several groups of older adults who live in aged care and community settings. We found that framing the world through a lens can powerfully transform a photographer’s relationship to the environment, and their sense of agency within it. This practice of intentional “seeing” creates opportunities for discovery in even the most familiar surroundings. As one aged care resident, Kathleen, put it: <blockquote> It’s given me a new sense of enjoyment and purpose and changed how I look at both life and seeing places in here that I’ve never seen before. </blockquote> <h2>Easy, meaningful and social</h2> So what makes photography particularly suited to older adults? Our research highlights some key factors. It’s accessible and familiar Photography has become one of the most democratic of creative pursuits. Most people carry a camera via their phone or tablet and know how to operate it. Older adults <a href="https://theconversation.com/the-digital-divide-small-social-programs-can-help-get-seniors-online-99082">are no exception</a>. This familiarity removes common barriers, such as the need to learn a new skill, and instead builds on existing knowledge. This makes photography an ideal creative expression; it requires no special training or equipment, and there is little room for doubt one’s capability. It’s meaningful Unlike many other creative activities offered to pass time, photography constitutes a meaningful activity for older adults. According to <a href="https://pubmed.ncbi.nlm.nih.gov/32022414/">research</a>, “meaningful” activities for older adults are those that are enjoyable, engaging, suited to individual skills, related to personal goals, and <a href="https://dx.doi.org/10.1080/1472586X.2021.1963828">connected to identity</a>. Photography can be exploratory, fun, and deeply personal. The outcomes can be <a href="https://onlinelibrary.wiley.com/doi/10.1111/ajag.70040">shared with others</a>, discussed, displayed and privately revisited, allowing connection to one’s self and the surrounding world. Seeing the familiar differently Photography honours a photographer’s life experience and perspectives. Each photograph becomes both a creative expression, and validation, of their unique viewpoint – and allows them to see the world through new eyes. During group <a href="https://www.collaborativephotography.com/projects/photowalks">photo walk</a> sessions held for my research, participants expressed delight in sharing the same experience of visiting a familiar place, while capturing their own distinct vision of it. When we returned to discuss the sessions, the group formed collective narratives, with each person adding their own unique contribution. Photography offers social and community connection while celebrating individual creativity and perspective. The different versions of Russell Anderson’s “iDIDIT!” sculpture on a walk on the Sunshine Coast. Being outside in the world While photography can be done anywhere, most people will head outside when exploring with a camera. This was particularly important for people living in aged care, who often didn’t venture out into the gardens. One participant, Margaret, was relearning how to walk after a stroke, and enjoyed our creative walks together. <figure class="align-right zoomable"></figure> She grew more confident with each walk, her purpose being to see parts of the residential aged care facility that she’d never accessed and photographed before. Going outside with a camera allowed her to connect to her new home. <h2>Putting it into practice</h2> The beautiful thing about photography is that anyone can do it, and there is no right or wrong. You can simply start by slowing down and looking for interesting shadows, textures, or details. For those working with older adults, photography is an adaptable, low-cost activity that works across various settings and abilities. You can do it indoors, from a wheelchair, sitting on a wheelie walker, or while getting some exercise. Photo walks, in particular, are a great way for photographers to share experiences and connect. <img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/257344/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/tricia-king-1025874">Tricia King</a>, Senior Lecturer in Photography, <a href="https://theconversation.com/institutions/university-of-the-sunshine-coast-1068">University of the Sunshine Coast</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Caring

Why do some people need less sleep than others?

<div class="theconversation-article-body"> Have you ever noticed how some people bounce out of bed after just a few hours of sleep, while others can barely function without a solid eight hours? Take Margaret Thatcher, for example. The former British prime minister was known for sleeping <a href="https://www.bbc.com/news/magazine-22084671">just four hours a night</a>. She worked late, rose early, and seemed to thrive on little sleep. But for most of us, that kind of sleep schedule would be disastrous. We’d be groggy, unfocused, and reaching for sugary snacks and caffeinated drinks by mid-morning. So why do some people seem to need less sleep than others? It’s a question that’s fascinated scientists for years. Here’s what we know so far. <h2>Natural short sleepers</h2> There is a small group of people who don’t need much sleep. We call them <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6879540/">natural short sleepers</a>. They can function perfectly well on just four to six hours of sleep each night, often for their entire lives. Generally they <a href="https://academic.oup.com/sleep/article/44/Supplement_2/A154/6260529">don’t feel tired</a>, they don’t nap, and they don’t suffer the usual negative consequences of sleep deprivation. Scientists call this the natural short sleep phenotype – a biological trait that allows people to get all the benefits of sleep in less time. In 2010 researchers discovered genetic mutations that help explain this phenomenon. Natural short sleepers carry rare variants <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC2884988/">in certain genes</a>, which seem to make their sleep more efficient. More recently, a <a href="https://www.pnas.org/doi/epub/10.1073/pnas.2500356122">2025 study</a> assessed a woman in her 70s with one of these rare mutations. Despite sleeping just six hours a night for most of her life, she remained physically healthy, mentally sharp, and led a full, active life. Her body, it seems, was simply wired to need less sleep. We’re still learning about how common these genetic mutations are and why they occur. <h2>Not everyone who sleeps less is a natural short sleeper</h2> But here’s the catch: most people who think they’re natural short sleepers aren’t. They’re just chronically sleep-deprived. Often, their short sleep is due to long work hours, social commitments, or a belief sleeping less is a sign of strength or productivity. In today’s hustle culture, it’s common to hear people boast about getting by on only a few hours of sleep. But for the average person, that’s not sustainable. The effects of short sleep build up over time, creating what’s known as a “sleep debt”. This <a href="https://www.sciencedirect.com/science/article/pii/S0149763417301641">can lead to</a> poor concentration, mood swings, micro-sleeps (brief lapses into sleep), reduced performance and even <a href="https://www.sciencedirect.com/science/article/pii/S1389945716301381">long-term health risks</a>. For example, short sleep has been linked to an increased risk of obesity, diabetes, high blood pressure and cardiovascular disease (heart disease and stroke). <h2>The weekend catch-up dilemma</h2> To make up for lost sleep during the week, many people try to “catch up” on weekends. This can help repay some of the sleep debt that has accumulated in the short term. Research <a href="https://www.sciencedirect.com/science/article/pii/S2352721823001663?via%3Dihub">suggests</a> getting one to two extra hours of sleep on the weekend or taking naps when possible may help reduce the negative effects of short sleep. However, it’s not a perfect fix. Weekend catch-up sleep and naps may not fully resolve sleep debt. The topic remains one of ongoing scientific debate. A recent <a href="https://academic.oup.com/sleep/article/47/11/zsae135/7696120">large study</a> suggested weekend catch-up sleep may not offset the cardiovascular risks associated with chronic short sleep. What’s more, large swings in sleep timing can disrupt your body’s <a href="https://www.nature.com/articles/s41598-017-03171-4">internal clock</a>, and sleeping in too much on weekends may make it harder to fall asleep on Sunday night, which can mean starting the working week less rested. Increasing evidence indicates <a href="https://academic.oup.com/sleep/article/47/1/zsad253/7280269">repeated cycles of irregular sleep</a> may have an important influence on general health and the risk of early death, potentially even more so than how long we sleep for. Ultimately, while moderate catch-up sleep might offer some benefits, it’s no substitute for consistent, high-quality sleep throughout the week. That said, maintaining such regularity can be particularly challenging for people with non-traditional schedules, such as shift workers. <h2>So, was Thatcher a true natural short sleeper?</h2> It’s hard to say. Some reports suggest <a href="https://www.theguardian.com/lifeandstyle/2021/aug/27/from-aristotle-to-einstein-a-brief-history-of-power-nappers">she napped during the day</a> in the back of a car between meetings. That could mean she was simply sleep-deprived and compensating for an accumulated sleep debt when she could. Separate to whether someone is a natural short sleeper, there are a range of other reasons people may need more or less sleep than others. Factors <a href="https://www.sleephealthfoundation.org.au/sleep-topics/how-much-sleep-do-you-really-need">such as age</a> and underlying health conditions can significantly influence sleep requirements. For example, older adults often experience changes in their circadian rhythms and are more likely to suffer from fragmented sleep due to conditions <a href="https://link.springer.com/article/10.1007/s00702-019-02067-z">such as arthritis</a> or <a href="https://link.springer.com/article/10.1007/s11886-023-01939-x">cardiovascular disease</a>. Sleep needs vary from person to person, and while a lucky few can thrive on less, most of us need <a href="https://www.sleephealthfoundation.org.au/sleep-topics/how-much-sleep-do-you-really-need">seven to nine hours</a> a night to feel and function our best. If you’re regularly skimping on sleep and relying on weekends to catch up, it might be time to rethink your routine. After all, sleep isn’t a luxury – it’s a biological necessity.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/256342/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> By <a href="https://theconversation.com/profiles/kelly-sansom-2390567">Kelly Sansom</a>, Research Associate, College of Medicine and Public Health, Flinders University; Research Associate, Centre for Healthy Ageing, <a href="https://theconversation.com/institutions/murdoch-university-746">Murdoch University</a> and <a href="https://theconversation.com/profiles/peter-eastwood-2316718">Peter Eastwood</a>, Deputy Vice Chancellor, Research and Innovation, <a href="https://theconversation.com/institutions/murdoch-university-746">Murdoch University</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Body

What is grounding and can it improve your sleep?

<div class="theconversation-article-body">Have you ever felt an unexpected sense of calm while walking barefoot on grass? Or noticed your stress begin to fade as you stood ankle deep in the ocean? If so, you may have unknowingly “grounded” yourself to the earth. Grounding, <a href="https://www.sciencedirect.com/science/article/pii/S2319417022001573">also known as earthing</a>, is the practice of making direct physical contact with the Earth’s surface. Our ancestors embraced this trend without knowing it. But with the invention of indoor homes, footpaths, roads, and even shoes, we have become <a href="https://onlinelibrary.wiley.com/doi/10.1155/2012/291541">less physically connected with the earth</a>. Grounding has been suggested to have <a href="https://www.healthline.com/health/grounding">a number of benefits</a>, such as improving mood, and reducing stress and pain. But overall, there’s limited conclusive evidence on the benefits of grounding. Somewhat ironically, the concept of grounding in 2025 is heavily influenced by technology, rather than getting out into nature. Consumers are being hit with social media reels promoting a range of technologies that ground us, and improve our health. Among the most common are promises of improved sleep with the use of a grounding sheet or mat. But is this just another TikTok trend, or could these products really help us get a better night’s sleep? <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-captioned="" data-instgrm-permalink="https://www.instagram.com/reel/DHne7CasELA/?utm_source=ig_embed&utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"> </div> </div> </div> <div style="padding: 19% 0;"> </div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"> </div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <div style="padding: 12.5% 0;"> </div> <div style="display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;"> <div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);"> </div> <div style="background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;"> </div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);"> </div> </div> <div style="margin-left: 8px;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;"> </div> <div style="width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);"> </div> </div> <div style="margin-left: auto;"> <div style="width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);"> </div> <div style="background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);"> </div> <div style="width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);"> </div> </div> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;"> </div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/reel/DHne7CasELA/?utm_source=ig_embed&utm_campaign=loading" target="_blank" rel="noopener">A post shared by Grounding (@groundingofficial)</a> </div> </blockquote> <h2>Bringing the outdoors in</h2> The <a href="https://www.sciencedirect.com/science/article/pii/S2319417022001585">human body is conductive</a>, which means it can exchange electricity with Earth and artificial sources, such as electronic devices or objects. (Sometimes, this exchange can result in an electric or <a href="https://theconversation.com/why-do-i-get-static-shocks-from-everyday-objects-is-it-my-shoes-240554">static shock</a>.) Proponents of grounding <a href="https://www.sciencedirect.com/science/article/pii/S1550830719305476">claim the practice reconnects</a> “the conductive human body to the Earth’s natural and subtle surface electric charge”. They credit this process with physiological and psychological benefits (but again, the evidence is limited). Grounding technologies can vary in type (for example, under-desk foot mats, mattress toppers and bed sheets) but all are designed to provide a path for electric charges to flow between your body and the earth. The bottom prong you see in your three-prong wall socket is a “ground” or “earth” terminal. It provides a direct connection to earth via your building’s wiring, diverting excess or unsafe voltage into the ground. This protects you and your devices from potential <a href="https://store.standards.org.au/reader/as-nzs-3112-2017?preview=1&utm">electrical faults</a>. <a href="https://www.mdpi.com/2227-9059/11/1/57">Grounding technology</a> uses this terminal as a pathway for the proposed electrical exchange between you and earth, while in the comfort of your home. <h2>Could grounding improve your sleep?</h2> The research in this area is still emerging. A <a href="https://www.sciencedirect.com/science/article/pii/S2212958825000059">2025 study</a> from Korea recruited 60 participants, gave half of them a grounding mat, and gave the other half a visually identical mat that didn’t have grounding technology. The researchers used a “double-blind” protocol, meaning neither the participants nor the researchers knew which participants were given grounding mats. All participants wore sleep trackers and were asked to use their mat (that is, sit or lie on it) for six hours per day. The researchers found that after 31 days, participants in the grounding mat group slept longer on average (as measured by their sleep trackers) than those in the control group. The researchers also used questionnaires to collect measures of insomnia, sleep quality, daytime sleepiness, and stress. After 31 days, participants in both groups improved on all measures. There were no differences between the grounded and ungrounded groups for sleep quality, daytime sleepiness, and stress. And while grounded participants showed significantly lower insomnia severity after the intervention, this difference was also present at the start of the study. So it’s unclear if grounding had a tangible impact on sleep. In another double-blind study, published in 2022, researchers in Taiwan examined the effectiveness of using grounding mats to improve sleep among patients with Alzheimer’s disease. The findings indicated that spending <a href="https://www.mdpi.com/2227-9032/10/3/581">30 minutes on a grounding mat</a> five times per week resulted in improved sleep quality. While previous research has suggested using grounding technologies may lead to <a href="https://pubmed.ncbi.nlm.nih.gov/25748085/">improvements in mood</a>, no differences were seen in measures of anxiety and depression in this study. <h2>Grounding for gains?</h2> Grounding technology has also been touted as <a href="https://www.tiktok.com/@down_to_ground/video/7310937768811597074?q=grounding%20mattress&t=1742787657768">having other benefits</a>, such as reducing pain and inflammation. A <a href="https://doi.org/10.3389/fphys.2019.00035">2019 study</a> found participants who slept on a grounding mat after intense exercise felt less sore and showed lower levels of inflammation in their blood compared to those who were ungrounded. Grounding after a workout may help you feel better and recover faster, but it’s still unclear whether and how grounding affects long-term training results or fitness gains. <h2>Add to cart?</h2> So should you cash in on your favourite influencer’s discount code and grab a grounding mat? At the risk of spouting a common cliche of cautious scientists, our answer is that we don’t know yet. What we do know is the existing research, albeit emerging, has shown no evidence grounding technology can negatively affect your sleep or recovery after exercise. So if you love your grounding mat or grounding sheet, or want to see if grounding works for you, feel free to give it a go. Keep in mind, grounding products can retail for anywhere from around A$30 to $300 or more. On the other hand, grounding on the grass in the great outdoors is free. While there’s limited evidence that grounding outdoors can improve sleep, spending time in outdoor light may itself benefit <a href="https://pubmed.ncbi.nlm.nih.gov/34488088/">sleep, regulate circadian rhythms</a>, and improve mood. Finally, while grounding could be an interesting strategy to try, if you’re experiencing ongoing problems with your sleep, or suspect you may have a sleep disorder, the first step should be reaching out to a medical professional, such as your GP.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/253347/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> By <a href="https://theconversation.com/profiles/dean-j-miller-808724">Dean J.

What are sleep retreats? A sleep scientist explains the latest wellness trend

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/jason-ellis-280919">Jason Ellis</a>, <a href="https://theconversation.com/institutions/northumbria-university-newcastle-821">Northumbria University, Newcastle</a> Considering the effect of poor sleep on the individual as well as on <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC5627640/">society and the economy</a>, it is hardly surprising sleep has become an intense area of research focus in recent years. Most recently we have seen an <a href="https://www.voguebusiness.com/story/beauty/the-beauty-consumer-trends-set-to-define-2025">increase</a> in the <a href="https://www.aspiretravelclub.co.uk/insight/in-focus-the-rise-of-sleep-retreats">offering of and appetite for</a> so-called <a href="https://www.countryandtownhouse.com/style/health-and-beauty/sleep-retreats/">sleep retreats</a>. But what are sleep retreats and are they helpful? As with any specialised retreat, there is no set formula for what a sleep retreat should focus on. As such, the range of what is available is incredibly variable, from retreats that just focus on a sleep-friendly environment (a cool, dark, quiet and comfortable bedroom in a luxurious location) to ones specifically aimed at managing a specific sleep disorder, using evidence-based therapies, such as cognitive behavioural therapy for insomnia. There are even ones that provide, among other things, a regimen of vitamins and minerals delivered intravenously. Most, however, fall somewhere between focusing on meditation, exercise and relaxation. Although there is good evidence that exercise, at the right intensity and duration, can be <a href="https://www.researchgate.net/profile/Helen-Driver-3/publication/10948102_Exercise_and_sleep/links/5f578ffca6fdcc9879d67d41/Exercise-and-sleep.pdf">beneficial for sleep</a>, it is unlikely that a lack of exercise alone causes poor sleep. Similarly, there is some, albeit poor quality, evidence that <a href="https://rsdjournal.org/index.php/rsd/article/view/40186">meditation and relaxation improve sleep quality</a>. As such, it is unlikely that these treatments alone will fix a sleep problem. The main challenge is that sleep, as with diet or exercise, is just an overarching term for a complex behaviour, one that is influenced and can influence almost every area of a person’s life. For example, I am <a href="https://link.springer.com/article/10.1007/s12011-022-03162-1">hearing a lot</a> about supplementing with magnesium to aid sleep, but this is only likely to be beneficial if you are <a href="https://www.sciencedirect.com/science/article/abs/pii/B9780124201682000314">deficient in the first place</a>. <h2>What to consider before you splash the cash</h2> So, should we approach the sleep retreat with caution? Not necessarily, it is more a case of doing your homework. First, who does the sleep retreat cater for, and what do you hope to get from the retreat? The busy executive who only allows themselves four hours of sleep a night will have very different expectations and experiences to a person who has undiagnosed sleep apnoea and sleeps for nine hours but wants to know why they are so sleepy during the day. This leads to the second consideration: what kind of pre-screening (for conditions that might be causing insomnia) and personalisation do they offer? Many retreats advertise an individual consultation as part of the package but don’t really say what that will cover (a sleep, medical and psychiatric history and lifestyle assessment should be done as a <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/jsr.14035">bare minimum</a>. This is vital when we consider that while well-established, evidence-based treatments for a variety of sleep disturbances and disorders exist, they are not suitable for everyone. Also, there is a <a href="https://pubs.rsc.org/en/content/articlelanding/2024/fo/d4fo01113a/unauth">perception</a> that non-pharmacological therapies, including nutraceuticals (products derived from food sources that said to have health benefits) and over-the-counter remedies (such as antihistamines, melatonin and valerian), don’t have side-effects, which is <a href="https://pubs.rsc.org/en/content/articlelanding/2024/fo/d4fo01113a/unauth">not necessarily the case</a>. The final considerations are: who is delivering the retreat? And is what they are offering based on sound scientific evidence? Considering certification in sleep medicine is a hot topic in the sleep community at the moment, it is worth doing some research. For example, in the UK there is no pathway to becoming a sleep medicine specialist, consultant or coach. So who is leading the sleep retreat and is what they offering evidence-based?<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/247632/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/jason-ellis-280919">Jason Ellis</a>, Professor of Sleep Science, <a href="https://theconversation.com/institutions/northumbria-university-newcastle-821">Northumbria University, Newcastle</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

What are cooling blankets? Can they really help me sleep?

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/linda-grosser-1461631">Linda Grosser</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> and <a href="https://theconversation.com/profiles/luana-main-2270550">Luana Main</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> You wake up exhausted from yet another hot night of tossing and turning, with very little sleep. So you might be tempted to buy a “cooling blanket” after reading rave reviews on social media. Or you might have read online articles with <a href="https://www.news.com.au/checkout/home-and-garden/bedroom/bedding/best-cooling-blankets/news-story/118ce05eba1e7d5cdff3aeadae5ae940">taglines such as</a>: <blockquote> Stop waking up in a puddle of sweat with our roundup of the best cooling blankets – including a top-rated option from Amazon that ‘actually works’. </blockquote> But what are cooling blankets? And can they help you get a restful night? <h2>We know a cooler bedroom is best</h2> First, let’s look at why a cooler environment helps us sleep better at night. Our body’s internal temperature has a <a href="https://www.sleepfoundation.org/circadian-rhythm">circadian rhythm</a>, meaning it fluctuates throughout the day. A couple of hours before bed, it drops about <a href="https://www.sciencedirect.com/science/article/pii/S1087079203000236">0.31°C</a> to help you fall asleep. It will drop about <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7323637/">another 2°C</a> across the night to help you stay asleep. During sleep, your internal temperature and skin work together to achieve a balance between losing and producing heat. Your skin has sensors that pick-up changes in the environment around you. If it gets too warm, these sensors let your body know, which may cause you to kick-off blankets or bed clothes and wake more often leading to poorer sleep quality. <a href="https://www.thensf.org/what-is-sleep-quality/">Sleep quality</a> is an important component of sleep health ensuring you get the physical, mental and emotional benefits that come from a good night’s sleep. The <a href="https://www.sciencedirect.com/science/article/pii/S0360132318300325">ideal temperature</a> for sleep varies depending on the season and type of bedding you have but falls between 17°C and 28°C. Keeping your sleeping environment within this range will help you to get the best night’s rest. <h2>So what are cooling blankets?</h2> Cooling blankets are designed to help regulate your body temperature while you sleep. Different technologies and materials are used in their design and construction. We’re not talking about <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC2206487/">hospital-grade</a> cooling blankets that are used to reduce fever and prevent injury to the nervous system. These use gel pads with circulating water, or air-cooling systems, connected to automatic thermostats to monitor someone’s temperature. Instead, the type of consumer-grade cooling blankets you might see advertised use a blend of lightweight, breathable materials that draw moisture away from the skin to help you stay cool and dry through the night. They look like regular blankets. Common materials include cotton, bamboo, silk or the fibre <a href="https://goodonyou.eco/how-ethical-is-tencel/">Lyocell</a>, all of which absorb moisture. Manufacturers typically use a <a href="https://www.sleepfoundation.org/best-sheets/best-thread-count-for-sheets">thread count</a> of <a href="https://www.trustsleep.com/how-do-cooling-blankets-work/">300-500</a>, creating air pockets that enhance airflow and moisture evaporation. Some blankets feature a <a href="https://getrest.com.au/blogs/all/unveiling-the-secrets-of-q-max-the-key-to-a-perfect-nights-sleep">Q-Max rating</a>, which indicates how cool the fabric feels against your skin. The higher the value, the cooler the fabric feels. Others feature <a href="https://www.trustsleep.com/how-do-cooling-blankets-work/">phase change materials</a>. These materials were developed by <a href="https://spinoff.nasa.gov/Spinoff2009/ch_4.html">NASA</a> for space suits to keep astronauts comfortable during a spacewalk where temperatures are from roughly <a href="https://www.nasa.gov/humans-in-space/spacewalk-spacesuit-basics/">-157°C to 121°C</a>. Phase change materials in cooling blankets absorb and hold heat producing a cooling effect. <h2>Do they work?</h2> If you believe online reviews, yes, cooling blankets can cool you down and help you sleep better in warmer weather or if you get too hot using normal sheets and blankets. However, there is little scientific research to see if these consumer-grade products work. In a 2021 <a href="https://www.mdpi.com/2071-1050/13/16/9099">study</a> exploring sleep quality, 20 participants slept for three nights under two different conditions. First, they slept with regular bed sheets in an air-conditioned room with the temperature set to their preference. Then, they used cooling bed sheets in an air-conditioned room where the temperature was set 3°C higher than their preference. Participants reported good sleep quality in both conditions but preferred the warmer room with its cooling sheets. This may suggest the use of cooling bedding may help provide a more comfortable night’s sleep. But everyone’s cooling needs varies depending on things like age, health, body temperature, the space you sleep in, and personal preferences. So while these products may work for some people who may be motivated to leave a good review, they may not necessarily work for you. <h2>Are they worth it?</h2> There’s a wide variety of cooling blankets available at different prices to suit various budgets. Positive customer reviews might encourage a purchase, especially for individuals experiencing disrupted sleep at night due to heat. Yet, these cooling blankets have limited scientific research to show they work and to say if they’re worth it. So it’s up to you. <h2>What else can I do if I’m a hot sleeper?</h2> If a cooling blanket isn’t for you, there are other things you can do to stay cool at night, such as: <ul> <li> using air conditioning or a fan </li> <li> placing a damp towel under or over you </li> <li> wearing lightweight or minimal sleepwear and avoiding thick or synthetic fabrics, such as nylon, that can trap heat </li> <li> if you usually share a bed, on hot nights, consider sleeping by yourself to avoid excess body heat from your partner. </li> </ul> On a final note, if you often struggle with hot, disturbed sleep, you can check in with your health-care provider. They can see if there is a medical explanation for your disturbed sleep and advise what to try next.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/244158/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/linda-grosser-1461631">Linda Grosser</a>, Research Associate, Behaviour-Brain-Body Research Centre, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> and <a href="https://theconversation.com/profiles/luana-main-2270550">Luana Main</a>, Associate Professor in Applied Sport Science, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

There’s a link between walking speed and ageing well. Here’s how you can improve your pace

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/andres-rafales-perucha-1528635">Andrés Ráfales Perucha</a>, <a href="https://theconversation.com/institutions/universidad-san-jorge-5704">Universidad San Jorge</a> and <a href="https://theconversation.com/profiles/pablo-gargallo-aguaron-1528652">Pablo Gargallo Aguarón</a>, <a href="https://theconversation.com/institutions/universidad-san-jorge-5704">Universidad San Jorge</a> For decades, we have known that the way you walk, in particular your walking speed, is tied to your health. One study has even proposed that it be considered <a href="https://pubmed.ncbi.nlm.nih.gov/24812254/">a vital sign</a>, much like heart rate and blood pressure. <a href="https://pubmed.ncbi.nlm.nih.gov/26861693/">Various studies</a> have found a link between low walking speed in adults over 65 and a greater risk of cognitive impairment, cardiovascular disease, falls (which could lead to fractures), hospitalisation, and even an increased overall mortality rate. A higher walking speed, on the other hand, is associated with increased functional capacity, meaning a better ability to move around and do activities independently. It is also linked to <a href="https://www.thelancet.com/journals/lanhl/article/PIIS2666-7568(24)00092-8/fulltext">greater longevity</a>. But how fast should you walk? <a href="https://www.sciencedirect.com/science/article/abs/pii/S1568163714000646?dgcid=api_sd_search-api-endpoint">Studies</a> recommend a few simple tests, which principally consist of timing how long it takes a person to walk between two points at their usual pace. This <a href="https://www.physio-pedia.com/4_Metre_Walk_Test">test</a> is done over a distance of four metres. A speed of under 0.8 metres per second is associated with a greater risk of frailty. <h2>How to improve walking speed</h2> While there is slight disagreement as to the best exercise for increasing walking speed, the pattern that seems most effective is <a href="https://pubmed.ncbi.nlm.nih.gov/34409961/">multicomponent training</a>, which includes several different forms of exercise: <ol> <li> Balance exercises can help improve stability and prevent falls. Examples include walking in a straight line putting one foot in front of the other, or standing on one leg, alternating every 10-15 seconds. </li> <li> Flexibility exercises can improve mobility and reduce risk of injury. The benefits of movement in alleviating back pain are <a href="https://theconversation.com/back-pain-why-exercise-can-provide-relief-and-how-to-do-it-safely-162888">well documented</a>. </li> <li> Muscular exercises help build strength in the legs, buttocks and other body areas. These can be as straightforward as standing up and sitting down in a chair. </li> <li> Aerobic exercise improves stamina, and can include walking itself, or <a href="https://theconversation.com/seven-reasons-nordic-walking-is-better-for-you-than-the-normal-kind-187391">Nordic walking</a> (with hiking poles). </li> </ol> <h2>How much aerobic exercise do we need?</h2> The main <a href="https://www.who.int/publications/i/item/9789240014886">guides</a> on physical activity recommend that, provided they are physically and medically able, each adult should do at least 150 minutes of moderately intense aeoribic exercise per week. “Moderate” means you are not too out of breath to hold a conversation, but enough to notice an increased heart and breathing rate. There are few reasons not to do this kind of exercise, and it is beneficial for people with chronic illnesses, including cardiovascular issues, metabolic conditions, or even cancer. <h2>Muscle strength: How, and how much?</h2> Strengthening exercises have traditionally been recommended 2 to 3 times a week, with at least one set per exercise session of the main muscle groups: legs, buttocks, pectorals, back and arms. However, more recent studies suggest that doing less intense but more frequent strengthening exercises may be an effective way to <a href="https://pubmed.ncbi.nlm.nih.gov/34822137/">maintain muscle mass and strength</a>. This would mean doing them almost every day, including even small exercise “snacks” throughout the day. <h2>Use it or lose it</h2> If we don’t train them, muscle mass and strength decrease over time. This not only affects our mobility, but also increases the risk of health problems and even death. A little daily exercise can make a big difference. We therefore recommend that you try to maintain your physical condition as much as possible, both to improve your immediate health and prevent future problems. If you do not know where to start, the best option is always to consult a professional. If you have difficulties or limitations in exercising, a physiotherapist can help you to build a specialised exercise plan, or can adapt one to your needs.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/245880/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/andres-rafales-perucha-1528635">Andrés Ráfales Perucha</a>, Fisioterapeuta y Personal Docente e Investigador de la Universidad San Jorge.

"Alive and well": Fans confused over Dr Harry Cooper death announcement

Dr Harry Cooper and Channel Seven have been forced to clarify that the famous TV vet is alive and kicking after his Wikipedia page stated he had died. According to Cooper's Wiki page, the TV personality died at the age of 80 on November 16th 2024. However, Ben Fordham and his 2GB team have confirmed that this is not the case. "[Dr. Harry] has had a bit of a shock this week, courtesy of something that appeared online," explained Fordham on his popular radio show. "This week we were contacted by a listener, they alerted us to the fact that according to Google and Wikipedia, Dr. Harry Cooper was no longer with us!" Fordham explained that he had done his own investigations of the claims and observed the Wikipedia page in question, which read that "Dr. Harry Cooper OAM, more commonly known as Dr. Harry, an Australian vet and TV personality best known for his media appearances, born February 20, 1943, died November 16, 2024." The unofficial death notice prompted several listeners to reach out to the team at 2GB, asking if they'd heard any news about Dr. Harry's alleged death. "A fan of Dr. Harry Cooper got in touch w us a couple of days ago and said, 'Did you know that Dr. Harry had died?," shared Fordham. "And we all looked at each other and said, 'No?' "And then we got another message, 'Can you confirm that Dr. Harry has passed away?' Again, we were looking online, and he was in New Idea at the start of the year celebrating his 80th birthday." "And the most recent story about Dr. Harry was from September, when he visited a camel farm." In order to confirm once and for all, Fordham reached out to the Seven Network, who provided a statement revealing the good news that, "Harry is alive and well." "After tipping off Seven, the reference to his death has been removed from Wikipedia," Fordham added. "So, its another reminder – you can't believe everything you read."

Humans evolved to share beds – how your sleeping companions may affect you now

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/goffredina-spano-2240566">Goffredina Spanò</a>, <a href="https://theconversation.com/institutions/kingston-university-949">Kingston University</a> and <a href="https://theconversation.com/profiles/gina-mason-2240569">Gina Mason</a>, <a href="https://theconversation.com/institutions/brown-university-1276">Brown University</a> <a href="https://www.cell.com/trends/ecology-evolution/fulltext/S0169-5347(24)00176-9">Recent research</a> on animal sleep behaviour has revealed that sleep is influenced by the animals around them. Olive baboons, for instance, sleep less as group sizes increase, while mice can synchronise their rapid eye movement (REM) cycles. In western society, many people expect to sleep alone, if not with a romantic partner. But as with other group-living animals, human co-sleeping is common, despite some <a href="https://www.sciencedirect.com/science/article/abs/pii/S1389945710000377">cultural</a> and <a href="https://www.sciencedirect.com/science/article/abs/pii/S2352721820303053?via%3Dihub">age-related variation</a>. And in many cultures, bedsharing with a relative is considered typical. Apart from <a href="https://www.sciencedirect.com/science/article/abs/pii/S1389945710000377">western countries</a>, caregiver-infant co-sleeping is common, with rates as high as <a href="https://www.sciencedirect.com/science/article/abs/pii/S1087079216000265">60-100%</a> in parts of South America, Asia and Africa. Despite its prevalence, infant co-sleeping is controversial. Some western perspectives, that value self-reliance, argue that sleeping alone promotes self-soothing when the baby wakes in the night. But <a href="https://www.tandfonline.com/doi/abs/10.1080/00221325.2021.1905599">evolutionary scientists argue</a> that co-sleeping has been important to help keep infants warm and safe throughout human existence. <a href="https://www.sleephealthjournal.org/article/S2352-7218(22)00077-8/abstract">Many cultures</a> do not expect babies to self-soothe when they wake in the night and see night wakings as a normal part of breastfeeding <a href="https://www.sciencedirect.com/science/article/pii/S1389945713002220?via%3Dihub">and development</a>. Concerns about Sudden Infant Death Syndrome (Sids) have often led paediatricians to discourage bed-sharing. However, when studies control for <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0107799">other Sids risk factors</a> including unsafe sleeping surfaces, Sids risk does not seem to differ statistically between co-sleeping and solitary sleeping infants. This may be one reason why agencies such as the <a href="https://publications.aap.org/pediatrics/article/150/1/e2022057990/188304/Sleep-Related-Infant-Deaths-Updated-2022?autologincheck=redirected">American Academy of Pediatrics</a>, the <a href="https://www.nice.org.uk/guidance/qs37/chapter/Quality-statement-5-Safer-practices-for-bed-sharing">National Institute for Health and Care Excellence</a> and the <a href="https://www.nhs.uk/conditions/baby/caring-for-a-newborn/reduce-the-risk-of-sudden-infant-death-syndrome/">NHS</a> either <a href="https://publications.aap.org/pediatrics/article/150/1/e2022057990/188304/Sleep-Related-Infant-Deaths-Updated-2022">recommend that</a> infants “sleep in the parents’ room, close to the parents’ bed, but on a separate surface,” or, if bedsharing, to make sure that the infant <a href="https://www.nice.org.uk/guidance/qs37/chapter/Quality-statement-5-Safer-practices-for-bed-sharing">“sleeps on a firm, flat mattress”</a> without pillows and duvets, rather than discouraging co-sleeping altogether. Researchers don’t yet know whether co-sleeping causes differences in sleep or, whether co-sleeping happens because of these differences. However, experiments in the 1990s suggested that co-sleeping can <a href="https://onlinelibrary.wiley.com/doi/10.1002/ajpa.20736">encourage more sustained and frequent bouts of breastfeeding</a>. Using sensors to measure brain activity, this research also suggested that infants’ and caregivers’ sleep may be lighter during co-sleeping. But researchers speculated that this lighter sleep may actually <a href="https://www.tandfonline.com/doi/full/10.1080/00221325.2021.1905599">help protect against Sids</a> by providing infants more opportunities to rouse from sleep and develop better control over their respiratory system. Other advocates believe that co-sleeping <a href="https://www.sciencedirect.com/science/article/abs/pii/S0163638319301237">benefits infants’ emotional and mental health</a> by promoting parent-child bonding and aiding infants’ <a href="https://www.tandfonline.com/doi/full/10.3109/10253890.2012.742057">stress hormone regulation</a>. However, current data is inconclusive, with most studies showing <a href="https://www.sciencedirect.com/science/article/abs/pii/S0163638319301249?via%3Dihub">mixed findings</a> or <a href="https://www.tandfonline.com/doi/full/10.1080/14616734.2024.2380427">no differences</a> between co-sleepers and solitary sleepers with respect to short and long-term mental health. <h2>Co-sleeping in childhood</h2> Childhood co-sleeping past infancy is also fairly common according to <a href="https://www.sciencedirect.com/science/article/abs/pii/S1389945713011076?via%3Dihub">worldwide surveys</a>. A <a href="https://publications.aap.org/pediatrics/article-abstract/126/5/e1119/65347/Relationship-Between-Bed-Sharing-and-Breastfeeding">2010 survey</a> of over 7,000 UK families found 6% of children were constant bedsharers up to at least four years old. Some families adopt co-sleeping <a href="https://capmh.biomedcentral.com/articles/10.1186/s13034-023-00607-w">in response to</a> their child having trouble sleeping. But child-parent bedsharing in many countries, including some western countries <a href="https://onlinelibrary.wiley.com/doi/10.1111/j.1471-6712.2005.00358.x">like Sweden</a> where children often co-sleep with parents until school age, is viewed culturally as part of a nurturing environment. It is also common for siblings to share a room or even a bed. A <a href="https://www.tandfonline.com/doi/full/10.1080/00221325.2021.1916732">2021 US study</a> found that over 36% of young children aged three to five years bedshared in some form overnight, whether with caregivers, siblings, pets or some combination. Co-sleeping decreases but is still present among older children, with up to <a href="https://onlinelibrary.wiley.com/doi/10.1111/fare.12955">13.8% of co-sleeping parents</a> in Australia, the UK and other countries reporting that their child was between five and 12 years old when they engaged in co-sleeping. Two recent US studies using wrist-worn actigraphs (motion sensors) to track sleep indicated that kids who bedshare may have <a href="https://jcsm.aasm.org/doi/10.5664/jcsm.11352">shorter sleep durations</a> than children who sleep alone. But this shorter sleep duration <a href="https://www.tandfonline.com/doi/full/10.1080/00221325.2021.1916732">is not explained by</a> greater disruption during sleep. Instead, bedsharing children may lose sleep by <a href="https://www.tandfonline.com/doi/full/10.1080/00221325.2021.1916732">going to bed later than</a> solitary sleepers. The benefits and downsides of co-sleeping may also differ in children with conditions such as <a href="https://www.sciencedirect.com/science/article/abs/pii/S1389945717303842">autism spectrum disorder</a>, <a href="https://link.springer.com/article/10.1007/s10802-017-0387-1">mental health disorders</a> and <a href="https://onlinelibrary.wiley.com/doi/10.1111/dmcn.13300">chronic illnesses</a>. These children may experience heightened anxiety, sensory sensitivities and physical discomfort that make falling and staying asleep difficult. For them, co-sleeping can provide <a href="https://link.springer.com/article/10.1007/s11325-018-1710-y">reassurance</a>. <h2>Adults sharing beds</h2> According to <a href="https://www.sleepfoundation.org/wp-content/uploads/2018/10/NSF_Bedroom_Poll_Report_1.pdf">a 2018 survey</a> from the US National Sleep Foundation, 80-89% of adults who live with their significant other share a bed with them. Adult bedsharing has shifted over time from pre-industrial <a href="https://academic.oup.com/ahr/article-abstract/106/2/343/64370?redirectedFrom=fulltext">communal arrangements</a>, including whole families and other household guests, to <a href="https://academic.oup.com/jdh/article-abstract/23/3/275/359439?redirectedFrom=fulltext">solo sleeping</a> in response to hygiene concerns as germ theory became accepted. Many couples find that bedsharing boosts their <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC1978364/">sense of closeness</a>. Research shows that bedsharing with your partner can lead to <a href="https://onlinelibrary.wiley.com/doi/10.1155/2017/8140672">longer sleep times</a> and a <a href="https://academic.oup.com/sleep/article-abstract/17/4/308/2753131">feeling of better sleep</a> overall. Bedsharing couples also often <a href="https://www.frontiersin.org/journals/psychiatry/articles/10.3389/fpsyt.2020.00583/full">get into sync</a> with each other’s sleep stages, which can enhance that feeling of intimacy. However, it’s not all rosy. Some studies indicate that females in heterosexual relationships may struggle more with sleep quality when bedsharing, as they can be <a href="https://link.springer.com/article/10.1111/j.1479-8425.2007.00320.x">more easily disturbed</a> by their male partner’s movements. Also, bedsharers can have less <a href="https://pubmed.ncbi.nlm.nih.gov/27624285/">deep sleep</a> than when sleeping alone, even though they feel like their sleep is better together. Many questions about co-sleeping remain unanswered. For instance, we don’t fully understand the developmental effects of co-sleeping on children, or the benefits of co-sleeping for adults beyond female-male romantic partners. But, some work suggests that co-sleeping can <a href="https://link.springer.com/article/10.1007/s11325-018-1710-y">comfort us</a>, similar to other <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/jsr.14174">forms of social contact</a>, and help to enhance <a href="https://onlinelibrary.wiley.com/doi/10.1002/ajpa.20736">physical synchrony</a> between parents and children. Co-sleeping doesn’t have a one-size-fits-all answer. But remember that western norms aren’t necessarily the ones we have evolved with. So consider factors such as <a href="https://www.sciencedirect.com/science/article/abs/pii/S1389945716301265">sleep disorders</a>, health and age in your decision to co-sleep, rather than what everyone else is doing.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/241803/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/goffredina-spano-2240566">Goffredina Spanò</a>, Lecturer in Developmental Cognitive Neuroscience, <a href="https://theconversation.com/institutions/kingston-university-949">Kingston University</a> and <a href="https://theconversation.com/profiles/gina-mason-2240569">Gina Mason</a>, Postdoctoral Research Fellow in Psychiatry and Human Behaviour, <a href="https://theconversation.com/institutions/brown-university-1276">Brown University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Body

How light tells you when to sleep, focus and poo

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/frederic-gachon-1379094">Frederic Gachon</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> and <a href="https://theconversation.com/profiles/benjamin-weger-1646210">Benjamin Weger</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> Exposure to light is crucial for our physical and mental health, as this and future articles in the series will show. But the timing of that light exposure is also crucial. This tells our body to wake up in the morning, when to poo and the time of day to best focus or be alert. When we’re exposed to light also controls our body temperature, blood pressure and even chemical reactions in our body. But how does our body know when it’s time to do all this? And what’s light got to do with it? <h2>What is the body clock, actually?</h2> One of the key roles of light is to re-set our body clock, also known as the circadian clock. This works like an internal oscillator, similar to an actual clock, ticking away as you read this article. But rather than ticking you can hear, the body clock is a network of genes and proteins that regulate each other. This network sends signals to organs via hormones and the nervous system. These complex loops of interactions and communications have a rhythm of about 24 hours. In fact, we don’t have one clock, we have trillions of body clocks throughout the body. The central clock is in the hypothalamus region of the brain, and each cell in every organ has its own. These clocks work in concert to help us adapt to the daily cycle of light and dark, aligning our body’s functions with the time of day. However, our body clock is not precise and works to a rhythm of about 24 hours (24 hours 30 minutes on average). So every morning, the central clock needs to be reset, signalling the start of a new day. This is why light is so important. The central clock is directly connected to <a href="https://journals.sagepub.com/doi/abs/10.1177/07487304231225706">light-sensing cells</a> in our retinas (the back of the eye). This daily re-setting of the body clock with morning light is essential for ensuring our body works well, in sync with our environment. In parallel, <a href="https://theconversation.com/does-it-matter-what-time-of-day-i-eat-and-can-intermittent-fasting-improve-my-health-heres-what-the-science-says-203762">when we eat food</a> also plays a role in re-setting the body clock, but this time the clock in organs other than the brain, such as the liver, kidneys or the gut. So it’s easy to see how our daily routines are closely linked with our body clocks. And in turn, our body clocks shape how our body works at set times of the day. <h2>What time of day?</h2> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/627494/original/file-20241023-14-729bed.gif?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/627494/original/file-20241023-14-729bed.gif?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/627494/original/file-20241023-14-729bed.gif?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=450&fit=crop&dpr=1 600w, https://images.theconversation.com/files/627494/original/file-20241023-14-729bed.gif?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=450&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/627494/original/file-20241023-14-729bed.gif?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=450&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/627494/original/file-20241023-14-729bed.gif?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=566&fit=crop&dpr=1 754w, https://images.theconversation.com/files/627494/original/file-20241023-14-729bed.gif?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=566&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/627494/original/file-20241023-14-729bed.gif?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=566&fit=crop&dpr=3 2262w" alt="" /></a><figcaption>Matt Garrow/The Conversation. <a class="source" href="https://delos.com/blog/why-natural-light-is-important-for-mental-and-physical-health/">Adapted from Delos</a>, <a class="license" href="http://creativecommons.org/licenses/by/4.0/">CC BY</a></figcaption></figure> <h2>Let’s take a closer look at sleep</h2> The naturally occurring brain hormone <a href="https://pubmed.ncbi.nlm.nih.gov/30311830/">melatonin</a> is linked to our central clock and makes us feel sleepy at certain times of day. When it’s light, our body stops making melatonin (its production is inhibited) and we are alert. Closer to bedtime, the hormone is made, then secreted, making us feel drowsy. Our sleep is also <a href="https://www.frontiersin.org/journals/physiology/articles/10.3389/fphys.2019.00944/full">partly controlled</a> by <a href="https://www.annualreviews.org/content/journals/10.1146/annurev-genom-121222-120306">our genes</a>, which are part of our central clock. These genes influence our <a href="https://theconversation.com/does-it-matter-what-time-i-go-to-bed-198146">chronotype</a> – whether we are a “lark” (early riser), “night owl” (late sleeper) or a “dove” (somewhere in between). But exposure to light at night when we are supposed to be sleeping can have harmful effects. Even dim light from light pollution can impair our <a href="https://www.pnas.org/doi/10.1073/pnas.2113290119">heart rate and how we metabolise sugar</a> (glucose), may lead to <a href="https://doi.org/10.1038/s44220-023-00135-8">psychiatric disorders</a> such as depression, anxiety and bipolar disorder, and increases the overall risk of <a href="https://www.pnas.org/doi/10.1073/pnas.2405924121">premature death</a>. The main reason for these harmful effects is that light “at the wrong time” disturbs the body clock, and these effects are more pronounced for “night owls”. This “misaligned” exposure to light is also connected to the detrimental health effects we often see in people who <a href="https://theconversation.com/why-does-night-shift-increase-the-risk-of-cancer-diabetes-and-heart-disease-heres-what-we-know-so-far-190652">work night shifts</a>, such as an increased risk of cancer, diabetes and heart disease. <h2>How about the gut?</h2> Digestion also follows a circadian rhythm. Muscles in the colon that help move waste <a href="https://doi.org/10.1111/j.1572-0241.2004.40453.x">are more active</a> during the day and slow down at night. The most significant increase in colon movement starts at 6.30am. This is one of the reasons why most people feel the urge to poo <a href="https://theconversation.com/why-do-i-poo-in-the-morning-a-gut-expert-explains-229624">in the early morning</a> rather than at night. The gut’s day-night rhythm is a direct result of the action of the gut’s own clock and the central clock (which synchronises the gut with the rest of the body). It’s also influenced by when we eat. <h2>How about focusing?</h2> Our body clock also helps control our attention and alertness levels by changing how our brain functions at certain times of day. Attention and alertness levels improve in the afternoon and evening but dip during the night and early morning. Those fluctuations <a href="https://www.frontiersin.org/journals/molecular-neuroscience/articles/10.3389/fnmol.2012.00050/full">impact performance</a> and can lead to decreased productivity and an <a href="https://www.nature.com/articles/s41598-019-40914-x">increased risk</a> of errors and accidents during the less-alert hours. So it’s important to perform certain tasks that <a href="https://pubmed.ncbi.nlm.nih.gov/30923475/">require our attention</a> at certain times of day. That includes driving. In fact, disruption of the circadian clock at the start of daylight savings – when our body hasn’t had a chance to adapt to the clocks changing – <a href="https://www.sciencedirect.com/science/article/pii/S0960982219316781?via%3Dihub">increases the risk</a> of a car accident, particularly in the morning. <h2>What else does our body clock control?</h2> Our body clock influences many other aspects of our biology, including: <ul> <li>physical performance by controlling the activity of our <a href="https://doi.org/10.1038/s41574-023-00805-8">muscles</a></li> <li>blood pressure by controlling the <a href="https://theconversation.com/what-time-of-day-should-i-take-my-medicine-125809">system of hormones</a> involved in regulating our blood volume and blood vessels</li> <li>body temperature by controlling our metabolism and our level of physical activity</li> <li>how our body handles drugs and toxins by <a href="https://doi.org/10.1080/17460441.2023.2224554">controlling enzymes</a> involved in how the liver and kidneys eliminate these substances from the body.</li> </ul> <h2>Morning light is important</h2> But what does this all mean for us? Exposure to light, especially in the morning, is crucial for synchronising our circadian clock and bodily functions. As well as setting us up for a good night’s sleep, increased morning light exposure benefits our <a href="https://www.sciencedirect.com/science/article/pii/S0165032721008612?via%3Dihub">mental health</a> and <a href="https://academic.oup.com/jcem/article/101/9/3539/2806883">reduces the risk of obesity</a>. So boosting our exposure to morning light – for example, by going for a walk, or having breakfast outside – can directly benefit our mental and metabolic health. However, there are other aspects about which we have less control, including <a href="https://www.sciencedirect.com/science/article/pii/S0168952524001100">the genes</a> that control our body clock.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/236780/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/frederic-gachon-1379094">Frederic Gachon</a>, Associate Professor, Physiology of Circadian Rhythms, Institute for Molecular Bioscience, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> and <a href="https://theconversation.com/profiles/benjamin-weger-1646210">Benjamin Weger</a>, NHMRC Emerging Leadership Fellow Institute for Molecular Bioscience, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Eight simple changes to our neighbourhoods can help us age well

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/jerome-n-rachele-251972">Jerome N Rachele</a>, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a>; <a href="https://theconversation.com/profiles/james-f-sallis-407885">James F Sallis</a>, <a href="https://theconversation.com/institutions/university-of-california-san-diego-1314">University of California, San Diego</a>, and <a href="https://theconversation.com/profiles/venurs-loh-118864">Venurs Loh</a>, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a> Where we live can play a big part in ageing well, largely because of the links between physical activity and wellbeing. <a href="https://www.ahuri.edu.au/__data/assets/pdf_file/0012/2181/AHURI_Final_Report_No214_Downsizing-amongst-older-Australians.pdf">Research shows</a> that two-thirds of Australians prefer to age in place. That is, we want to live independently in our homes for as long as we can. Our neighbourhoods and their design can then improve or hinder our ability to get out of the house and be physically active. The rapid ageing of Australia’s population only adds to the importance of neighbourhood design. In 2016, 15% of Australians were aged 65 or older. That proportion is <a href="https://www.aihw.gov.au/reports-statistics/population-groups/older-people/overview">projected to double</a> by 2056. These trends present several <a href="https://www.aihw.gov.au/reports-statistics/population-groups/older-people/reports">social and economic challenges</a>, particularly for the health sector. Designing neighbourhoods in ways that promote physical activity can help overcome these challenges. <h2>Eight simple steps</h2> The following is a short list of <a href="https://ijbnpa.biomedcentral.com/articles/10.1186/s12966-017-0471-5">evidence-based steps</a> local and state governments can take to assist older people to be physically active. These involve minor but effective changes to neighbourhood design. Improve footpaths: Research indicates that older people have a <a href="https://theconversation.com/why-older-people-get-osteoporosis-and-have-falls-68145">higher risk of falls</a>. Ensuring footpaths are level and crack-free, and free from obstructions, will encourage walking among older people – especially those with a disability. Connected pedestrian networks: Introducing footpaths at the end of no-through-roads and across long street blocks reduces walking distances to destinations. This makes walking a more viable option. Slowing traffic in high-pedestrian areas: Slowing traffic <a href="https://www.heartfoundation.org.au/images/uploads/publications/Safe-Speed-Evidence-Report.pdf">improves safety</a> by reducing the risk of a collision. It also reduces the risk of <a href="https://www.ncbi.nlm.nih.gov/pubmed/28557669">death and serious injury</a> in the event of a collision. Age-friendly street crossings: Installing longer pedestrian crossing light sequences gives older pedestrians <a href="https://academic.oup.com/ageing/article/41/5/690/47318/Most-older-pedestrians-are-unable-to-cross-the">more time to cross</a>, and installing refuge islands means those who walk more slowly can cross the street in two stages. Disabled access at public transport: Although a form of motorised transport, public transport users undertake more incidental physical activity compared with car users. This is because they walk between transit stops and their origins and destinations. Improving disabled access helps make public transport a viable option for more older people. Places to rest: <a href="https://bmcpublichealth.biomedcentral.com/articles/10.1186/1471-2458-13-1054">Providing rest spots</a> such as benches enables older people to break up their walk and rest when needed. Planting trees: Planting trees <a href="http://www.sciencedirect.com/science/article/pii/S0277953614004109?via%3Dihub">creates more pleasant scenery</a> to enjoy on a walk. It also provides shade on hot days. Improving safety: Ensuring that streets are well-lit and reducing graffiti and signs of decay are likely to <a href="https://www.ncbi.nlm.nih.gov/pubmed/24552845">improve perceptions of safety</a> among older people. <h2>Why physical activity matters</h2> Physical function – the ability to undertake everyday activities such as walking, bathing and climbing stairs – often declines as people age. The reason for this is that ageing is often accompanied by a reduction in muscle strength, flexibility and cardiorespiratory reserves. Regular physical activity can <a href="https://www.ncbi.nlm.nih.gov/pubmed/14552936">prevent or slow the decline</a> in physical function, even among those with existing health conditions. Middle-to-older aged adults can reduce their risk of physical function decline <a href="https://ijbnpa.biomedcentral.com/articles/10.1186/1479-5868-7-38">by 30%</a> with regular physical activity (at least 150 minutes per week). This includes recreational physical activity, like walking the dog, or incidental physical activity, such as walking to the shops or to visit friends. By making minor changes as outlined above, the health and longevity of our elderly population can be extended. Such changes will help our elderly age well in place. <a href="https://theconversation.com/profiles/jerome-n-rachele-251972">Jerome N Rachele</a>, Research Fellow in Social Epidemiology, Institute for Health and Ageing, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a>; <a href="https://theconversation.com/profiles/james-f-sallis-407885">James F Sallis</a>, Professorial Fellow, Institute for Health and Ageing, Australian Catholic University, and Emeritus Professor, Department of Family Medicine and Public Health, <a href="https://theconversation.com/institutions/university-of-california-san-diego-1314">University of California, San Diego</a>, and <a href="https://theconversation.com/profiles/venurs-loh-118864">Venurs Loh</a>, PhD Candidate, Institute for Health and Ageing, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Often when people come into our sleep clinic seeking treatment, they share ideas about healthy sleep. Many think when their head hits the pillow, they should fall into a deep and restorative sleep, and emerge after about eight hours feeling refreshed. They’re in good company – many Australians hold <a href="https://doi.org/10.1016/j.jpsychores.2014.09.011">the same belief</a>. In reality, healthy sleep is cyclic across the night, as you move in and out of the different stages of sleep, often waking up several times. Some people remember one or more of these awakenings, others do not. Let’s consider what a healthy night’s sleep looks like. <h2>Sleep cycles are a roller-coaster</h2> As an adult, our sleep moves through <a href="https://www.sleepfoundation.org/stages-of-sleep">different cycles</a> and brief awakenings during the night. Sleep cycles last roughly 90 minutes each. We typically start the night with lighter sleep, before moving into deeper sleep stages, and rising again into rapid eye movement (REM) sleep – the stage of sleep often linked to vivid dreaming. If sleeping well, we get most of our deep sleep in the first half of the night, with <a href="https://www.nhlbi.nih.gov/health/sleep/stages-of-sleep#:%7E:text=During%20REM%20sleep%2C%20your%20eyes,from%20acting%20out%20your%20dreams">REM sleep</a> more common in the second half of the night. Adults usually move through five or six sleep cycles in a night, and it is entirely <a href="https://doi.org/10.1016/j.jpsychores.2014.09.011">normal</a> to wake up briefly at the end of each one. That means we might be waking up five times during the night. This can increase with older age and still be healthy. If you’re not remembering these awakenings that’s OK – they can be quite brief. <h2>What does getting a ‘good’ sleep actually mean?</h2> You’ll often hear that adults <a href="https://www.sleephealthfoundation.org.au/sleep-topics/how-much-sleep-do-you-really-need#:%7E:text=Sleep%20requirements%20stabilise%20in%20early,their%20best%20the%20next%20day">need between seven and nine hours</a> of sleep per night. But good sleep is about more than the number of hours – it’s also about the quality. For most people, sleeping well means being able to fall asleep soon after getting into bed (within around 30 minutes), sleeping without waking up for long periods, and waking feeling rested and ready for the day. You shouldn’t be feeling excessively sleepy during the day, especially if you’re regularly getting at least seven hours of refreshing sleep a night (this is a rough rule of thumb). But are you noticing you’re feeling physically tired, needing to nap regularly and still not feeling refreshed? It may be worthwhile touching base with your general practitioner, as there a range of possible reasons. <h2>Common issues</h2> Sleep disorders are common. Up to <a href="https://pubmed.ncbi.nlm.nih.gov/35478719/">25% of adults</a> have insomnia, a sleep disorder where it may be hard to fall or stay asleep, or you may wake earlier in the morning than you’d like. Rates of common sleep disorders such as insomnia and <a href="https://www.mayoclinic.org/diseases-conditions/sleep-apnea/symptoms-causes/syc-20377631">sleep apnoea</a> – where your breathing can partially or completely stop many times during the night – also increase with age, affecting <a href="https://pubmed.ncbi.nlm.nih.gov/32280974/">20% of early adults</a> and 40% of people in <a href="https://pubmed.ncbi.nlm.nih.gov/35082023/">middle age</a>. There are effective treatments, so asking for help is important. Beyond sleep disorders, our sleep can also be disrupted by chronic health conditions – such as <a href="https://www.sciencedirect.com/science/article/abs/pii/S0012369218311139">pain</a> – and by <a href="https://onlinelibrary.wiley.com/doi/10.1111/jsr.13075">certain medications</a>. There can also be other reasons we’re not sleeping well. Some of us are woken by children, pets or traffic noise during the night. These “<a href="https://www.tandfonline.com/doi/full/10.1080/07420528.2021.2003375">forced awakenings</a>” mean we may find it harder to get up in the morning, take longer to leave bed and feel less satisfied with our sleep. For some people, night awakenings may have no clear cause. A good way to tell if these awakenings are a problem for you is by thinking about how they affect you. When they cause feelings of frustration or worry, or are impacting how we feel and function during the day, it might be a sign to seek some help. We also may struggle to get up in the morning. This could be for a range of reasons, including not sleeping long enough, going to bed or waking up at irregular times – or even your own <a href="https://www.sleephealthfoundation.org.au/sleep-categories/circadian-rhythm-disorders#:%7E:text=The%20circadian%20rhythms%20throughout%20the,regulation%20of%20our%20sleeping%20patterns">internal clock</a>, which can influence the time your body prefers to sleep. If you’re regularly struggling to get up for work or family needs, it can be an indication you may need to seek help. Some of these factors can be explored with a sleep psychologist if they are causing concern. <h2>Can my smart watch help?</h2> It is important to remember sleep-tracking devices can <a href="https://www.nature.com/articles/s41746-024-01016-9">vary in accuracy</a> for looking at the different sleep stages. While they can give a rough estimate, they are not a perfect measure. In-laboratory <a href="https://pubmed.ncbi.nlm.nih.gov/31277862/">polysomnography</a>, or PSG, is the best standard measure to examine your sleep stages. A PSG examines breathing, oxygen saturation, brain waves and heart rate during sleep. Rather than closely examining nightly data (including sleep stages) from a sleep tracker, it may be more helpful to look at the patterns of your sleep (bed and wake times) over time. <a href="https://jcsm.aasm.org/doi/10.5664/jcsm.8356">Understanding your sleep patterns</a> may help identify and adjust behaviours that negatively impact your sleep, such as your bedtime routine and sleeping environment. And if you find viewing your sleep data is making you feel worried about your sleep, this may not be useful for you. Most importantly, if you are concerned it is important to discuss it with your GP who can refer you to the appropriate specialist sleep health provider.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/238069/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/amy-reynolds-424346">Amy Reynolds</a>, Associate Professor in Clinical Sleep Health, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a>; <a href="https://theconversation.com/profiles/claire-dunbar-1651340">Claire Dunbar</a>, Research Associate, Sleep Health, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a>; <a href="https://theconversation.com/profiles/gorica-micic-187159">Gorica Micic</a>, Postdoctoral Research Fellow, Clinical Psychologist, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a>; <a href="https://theconversation.com/profiles/hannah-scott-424633">Hannah Scott</a>, Research Fellow in Sleep Health, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a>, and <a href="https://theconversation.com/profiles/nicole-lovato-60684">Nicole Lovato</a>, Associate Professor, Adelaide Institute for Sleep Health, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"Can you sleep at night?" Frustrated shopper confronts Woolies CEO over price gouging

A frustrated Woolworths shopper has called out the supermarket's CEO in store to demand answers about Woolies' record-breaking profits during the cost of living crisis. Chief executive Amanda Bardwell was walking around a Woolworths store in Wollongong when the heated exchange took place, with the whole thing captured on camera. The customer fired off hard-hitting questions to the CEO and other senior staff members, asking, "What do you have to say to the fact that your company is profiting off price gouging during the cost of living crisis?" Ms Bardwell, looking visibly shocked by the confrontation, replied, "Thank you for reaching out to us, we're doing everything we can to recognise that customers are doing it tough to make sure that they're able to get great prices." The woman didn't accept her answer, firing back, "I really don't believe that. Millions of people in Australia right now have to skip meals in order to survive, while you continue to make big bucks and working class people suffer. Can you sleep at night knowing that?" Ms Bardwell replied, "Our team are doing everything that we can to support our customers. We understand that it is an incredibly difficult time right now." A staff member then intervened, adding, "We have lowered prices and you see that right throughout our store… that's great value for our customers." Ms Bardwell thanked the customer for sharing her views and said Woolworths was doing "everything we can" to keep prices low for customers, before another staff member chimed in to say "It's actually illegal to film people in NSW without permission, with the CEO walking away. Social media users were quick to praise the woman for confronting Miss Bardwell, while sharing their own stories of being stung by hefty supermarket prices. "I'm sick of paying nearly $300 a week on groceries. That's choosing the cheapest products. My fridge still looks half empty when I unpack," one said. "I'm sure Coles and Woolworth management don't have cost of living crisis as they are getting bigger and bigger bonus year after year," a second wrote. Others took aim at one particular comment in the video, pointing out, "'It’s illegal to film in NSW without permission', yet Woolworths has how many cameras in every store? Cameras in people’s faces in self serve on every screen. Did they get our permission?" Another added, "If only their empathy was as big as their prices." Image credits: TikTok

New study finds epilepsy drug could reduce sleep apnoea symptoms

New research has found that a drug used for epilepsy could be used to reduce the symptoms of sleep apnoea. Obstructive sleep apnoea, which affects about one in 20 people, according to the National Institute for Health and Care Excellence in England, includes symptoms like snoring and it causes a person's breathing to start and stop during the night, with many requiring an aid to help keep their airways open. An international study has identified that taking sulthiame, a drug sold under the brand name Ospolot in Europe, may help prevent patients' breathing from temporarily stopping. This provides an additional option for those unable to use mechanical breathing aids like the Cpap machines. “The standard treatment for obstructive sleep apnoea is sleeping with a machine that blows air through a face mask to keep the airways open. Unfortunately, many people find these machines hard to use over the long term, so there is a need to find alternative treatments,” Prof Jan Hedner from Sahlgrenska university hospital and the University of Gothenburg in Sweden said. Researchers conducted a randomised controlled trial of almost 300 obstructive sleep apnoea patients across Europe, who did not use Cpap machines. They were divided into four groups and given either a placebo or different strengths of sulthiame. The study measured patients’ breathing, oxygen levels, heart rhythm, eye movements, as well as brain and muscle activity while asleep. It found after 12 weeks, those taking sulthiame had up to 50% fewer occasions where their breathing stopped, and higher levels of oxygen in their blood. However, a bigger study needs to be done to confirm the beneficial effects on a larger group. The findings, were presented at the European Respiratory Society Congress in Vienna, Austria. Erika Radford, the head of health advice at Asthma + Lung UK said the findings were a positive step forward in moving away from having to rely on mechanical breathing equipment. “This potential alternative to the current main treatment would make it easier for people to manage their condition,” she said.

Air traffic controller found asleep on the job

An air traffic controller has been found asleep on the job, with the incident prompting calls for better fatigue management, according to Australia's transport watchdog. The report by the Australian Transport Safety Bureau (ATSB) dates back to December 2022, when the Airservices Australia controller was found lying across two chairs with a blanket covering them at 5am. The controller had worked multiple night shifts with reduced extended rest periods, "which likely reduced their ability to obtain restorative sleep", the report claimed. ATSB chief commissioner Angus Mitchell said the controller had increased their chances of falling asleep "by lying across two chairs, not moving, and not undertaking activities to maintain mental alertness". When a colleague discovered the snoozing worker, there was no traffic in the Cairns airspace they were responsible for managing, which was usual for that time of day, and there were no scheduled flights until after their shift. However, the report highlighted the possible problems the incident pay have caused, saying if the traffic controller was woken up by a radio broadcast, they may have experienced "sleep inertia", with the risk of delayed communications, or incorrect instructions or actions. "There were no negative consequences from this occurrence, but it does highlight areas for improvement in work scheduling and fatigue risk management," said Mitchell . Since the incident, Airservices Australia has increased its overall number of air traffic controllers, and has also drawn up new guidelines and training about fatigue risk assessment. "Fatigue remains one of the most relevant ongoing concerns for safe transport, despite increased awareness across the transport sector," said Mitchell. Image credits: Shutterstock

Passenger sparks debate over travellers sleeping in aisle seats

A heated debate has erupted online after a passenger suggested those sitting in an aisle seat should remain alert and awake for the entire flight, with the only exception being if it's a long-flight of seven hours or more. “A person sitting in an aisle seat on a plane should not be allowed to sleep," they wrote on Reddit. The reason behind it, according to the passenger, is to ensure that middle and window seat passengers can access the toilet, get served by flight attendants, and evacuate quickly in an emergency. “There are some exceptions and those would probably be on any flight longer than seven hours. “But anything shorter than that, you should not be sleeping. What if the middle or window passenger needs the bathroom, or if the flight attendant needs to hand them something – You’ll be in the way.” They added that a snoozing aisle seat passenger could potentially slow down evacuation during an emergency and put everyone at risk. “Now you would be risking people’s lives because you fell asleep,” they wrote. Social media users flocked to the Reddit thread to share their thoughts. “Nah, just poke me and wake me up if you need me to get up or do something," one wrote. “I’m well aware that I’m in the way, believe me. I’m certainly not there because I wanted to be in the aisle seat.” “If you sleep in an aisle seat, you deal with people getting up. That’s the unwritten rule," another added. A few others supported the idea, but shared their own take on plane etiquette. “My take on this: if you sleep in the aisle seat, you must be okay with being woken up multiple times to let the folks in your row get up. “Other flight rules: middle seat gets the armrest, and window seat must raise the window shade during taxi, takeoff, and landing so the rest of us in the row can watch.” Image: Shutterstock

Food and exercise can treat depression as well as a psychologist, our study found. And it’s cheaper

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/adrienne-oneil-268324">Adrienne O'Neil</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> and <a href="https://theconversation.com/profiles/sophie-mahoney-1557294">Sophie Mahoney</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> Around <a href="https://www.aihw.gov.au/getmedia/6b19e493-0ebe-420f-a9a3-e48b26aace9f/aihw-aus-249-ib.pdf?v=20240628145747&inline=true">3.2 million</a> Australians live with depression. At the same time, <a href="https://www.aihw.gov.au/getmedia/6b19e493-0ebe-420f-a9a3-e48b26aace9f/aihw-aus-249-ib.pdf?v=20240628145747&inline=true">few</a> Australians meet recommended dietary or physical activity guidelines. What has one got to do with the other? Our world-first trial, <a href="https://www.thelancet.com/journals/lanwpc/article/PIIS2666-6065%2824%2900136-6/fulltext">published this week</a>, shows improving diet and doing more physical activity can be as effective as therapy with a psychologist for treating low-grade depression. Previous studies (including <a href="https://link.springer.com/article/10.1186/s12916-017-0791-y">our own</a>) have found “lifestyle” therapies are effective for depression. But they have never been directly compared with psychological therapies – until now. Amid a nation-wide <a href="https://www.health.gov.au/sites/default/files/2023-10/national-mental-health-workforce-strategy-2022-2032.pdf">shortage</a> of mental health professionals, our research points to a potential solution. As we found lifestyle counselling was as effective as psychological therapy, our findings suggest dietitians and exercise physiologists may one day play a role in managing depression. <h2>What did our study measure?</h2> During the prolonged COVID lockdowns, Victorians’ distress levels were <a href="https://onlinelibrary.wiley.com/doi/full/10.5694/mja2.50831">high and widespread</a>. Face-to-face mental health services were limited. Our trial targeted people living in Victoria with elevated distress, meaning at least mild depression but not necessarily a diagnosed mental disorder. Typical symptoms included feeling down, hopeless, irritable or tearful. We partnered with our <a href="https://www.barwonhealth.org.au/mhdas/">local mental health service</a> to recruit 182 adults and provided group-based sessions on Zoom. All participants took part in up to six sessions over eight weeks, facilitated by health professionals. Half were randomly assigned to participate in a program co-facilitated by an accredited practising dietitian and an exercise physiologist. That group – called the lifestyle program – developed nutrition and movement goals: <ul> <li>eating a wide variety of foods</li> <li>choosing high-fibre plant foods</li> <li>including high quality fats</li> <li>limiting discretionary foods, such as those high in saturated fats and added sugars</li> <li>doing enjoyable physical activity.</li> </ul> The second group took part in psychotherapy sessions convened by two psychologists. The psychotherapy program used cognitive behavioural therapy (CBT), the gold standard for treating depression in <a href="https://jamanetwork.com/journals/jamapsychiatry/article-abstract/2730724">groups and when delivered remotely</a>. In both groups, participants could continue existing treatments (such as taking antidepressant medication). We gave both groups <a href="https://link.springer.com/article/10.1186/s12888-022-03840-3">workbooks and hampers</a>. The lifestyle group received a food hamper, while the psychotherapy group received items such as a colouring book, stress ball and head massager. <h2>Lifestyle therapies just as effective</h2> We found similar results in each program. At the trial’s beginning we gave each participant a score based on their self-reported mental health. We measured them again at the end of the program. Over eight weeks, those scores showed symptoms of depression reduced for participants in the lifestyle program (42%) and the psychotherapy program (37%). That difference was not statistically or clinically meaningful so we could conclude both treatments were as good as each other. There were some differences between groups. People in the lifestyle program improved their diet, while those in the psychotherapy program felt they had increased their social support – meaning how connected they felt to other people – compared to at the start of the treatment. Participants in both programs increased their physical activity. While this was expected for those in the lifestyle program, it was less expected for those in the psychotherapy program. It may be because they knew they were enrolled in a research study about lifestyle and subconsciously changed their activity patterns, or it could be a positive by-product of doing psychotherapy. There was also not much difference in cost. The lifestyle program was slightly cheaper to deliver: A$482 per participant, versus $503 for psychotherapy. That’s because hourly rates differ between dietitians and exercise physiologists, and psychologists. <h2>What does this mean for mental health workforce shortages?</h2> Demand for mental health services is increasing in Australia, while at the same time the workforce <a href="https://www.health.gov.au/sites/default/files/2023-10/national-mental-health-workforce-strategy-2022-2032.pdf">faces worsening nation-wide shortages</a>. Psychologists, who provide <a href="https://www.aihw.gov.au/getmedia/6b19e493-0ebe-420f-a9a3-e48b26aace9f/aihw-aus-249-ib.pdf?v=20240628145747&inline=true">about half</a> of all mental health services, can have long wait times. Our results suggest that, with the appropriate training and guidelines, allied health professionals who specialise in diet and exercise could help address this gap. Lifestyle therapies can be combined with psychology sessions for multi-disciplinary care. But diet and exercise therapies could prove particularly effective for those on waitlists to see a psychologists, who may be receiving no other professional support while they wait. Many dietitians and exercise physiologists already have advanced skills and expertise in motivating behaviour change. Most accredited practising dietitians are trained in managing <a href="https://link.springer.com/content/pdf/10.1007/978-3-030-67929-3_38-1.pdf">eating disorders</a> or <a href="https://www.nature.com/articles/s41572-020-0200-2">gastrointestinal conditions</a>, which commonly overlap with depression. There is also a cost argument. It is <a href="https://journals.sagepub.com/doi/full/10.1177/1355819616668202">overall cheaper</a> to train a dietitian ($153,039) than a psychologist ($189,063) – and it takes less time. <h2>Potential barriers</h2> Australians with chronic conditions (such as diabetes) can access subsidised dietitian and exercise physiologist appointments under various Medicare treatment plans. Those with eating disorders can also access subsidised dietitian appointments. But mental health care plans for people with depression do not support subsidised sessions with dietitians or exercise physiologists, despite <a href="https://dietitiansaustralia.org.au/sites/default/files/2024-04/Dietitians%20Australia%20Mental%20Health%20Evidence%20Brief%202024.pdf">peak bodies</a> urging them to do so. Increased training, upskilling and Medicare subsidies would be needed to support dietitians and exercise physiologists to be involved in treating mental health issues. <a href="https://foodandmoodcentre.com.au/academy">Our training</a> and clinical <a href="https://www.tandfonline.com/doi/full/10.1080/15622975.2022.2112074">guidelines</a> are intended to help clinicians practising lifestyle-based mental health care within their scope of practice (activities a health care provider can undertake). <h2>Future directions</h2> Our trial took place during COVID lockdowns and examined people with at least mild symptoms of depression who did not necessarily have a mental disorder. We are seeking to replicate these findings and are now running <a href="https://foodandmoodcentre.com.au/projects/the-harmone-trial/">a study</a> open to Australians with mental health conditions such as major depression or bipolar disorder.
