Does eating cheese before bed really give you nightmares?

<div class="theconversation-article-body"> Have you heard people say eating cheese before bed will cause you to have vivid dreams or nightmares? It’s a relatively common idea. And this week, a <a href="https://www.frontiersin.org/journals/psychology/articles/10.3389/fpsyg.2025.1544475/full">new study</a> has landed this suggestion <a href="https://www.canberratimes.com.au/story/9005656/are-cheese-dreams-real-new-study-reveals-how-diet-affects-sleep/">back in the spotlight</a>. But is it true? Let’s unpack the evidence. <h2>A gouda night’s sleep?</h2> Canadian researchers recently <a href="https://www.frontiersin.org/journals/psychology/articles/10.3389/fpsyg.2025.1544475/full#h3">investigated this idea</a> in a sample of 1,082 undergraduate psychology students. The students completed a survey, which included questions about how they perceived their diet influenced their sleep and dreams. Some 40% of participants reported certain foods impacted their sleep, with 25% of the whole sample claiming certain foods worsened their sleep, and 20% reporting certain foods improved their sleep. Only 5.5% of respondents believed what they ate affected the nature of their dreams. But many of these people thought sweets or dairy products (such as cheese) made their dreams more strange or disturbing and worsened their sleep. In contrast, participants reported fruits, vegetables and herbal teas led to better sleep. <blockquote class="twitter-tweet"> Snacking on cheese late at night may haunt your dreams, Canadian study finds<a href="https://t.co/ne5poEo7N7">https://t.co/ne5poEo7N7</a> <a href="https://t.co/rMpSbzoGzk">pic.twitter.com/rMpSbzoGzk</a> — Edmonton Journal (@edmontonjournal) <a href="https://twitter.com/edmontonjournal/status/1940531062615990327?ref_src=twsrc%5Etfw">July 2, 2025</a></blockquote> This study used self-reporting, meaning the results rely on the participants recalling and reporting information about their sleep and dreams accurately. This could have affected the results. It’s also possible participants were already familiar with the notion that cheese causes nightmares, especially given they were psychology students, many of whom may have studied sleep and dreaming. This awareness could have made them more likely to notice or perceive their sleep was disrupted after eating dairy. In other words, the idea cheese leads to nightmares may have acted like a self-fulfilling prophecy and results may overestimate the actual likelihood of strange dreams. Nonetheless, these findings show some people perceive a connection between what they eat and how they dream. While there’s no evidence to prove cheese causes nightmares, there is evidence that does explain a link. <h2>The science behind cheese and nightmares</h2> Humans are diurnal creatures, meaning our body is primed to be asleep at night and awake during the day. Eating cheese before bed means we’re challenging the body with food at a time when it really doesn’t want to be eating. At night, our physiological systems <a href="https://doi.org/10.1016/j.smrv.2024.101953">are not primed to digest food</a>. For example, it takes longer for food to move through our <a href="https://doi.org/10.1111/j.1440-1681.2009.05254.x">digestive tract</a> at night compared with during the day. If we eat close to going to sleep, our body has to process and digest the food while we’re sleeping. This is a bit like running through mud – we can do it, but it’s slow and inefficient. Cheese can be particularly challenging to digest at night because of <a href="https://doi.org/10.1016/j.idairyj.2006.11.006">high concentrations of fat and protein</a>, which <a href="https://doi.org/10.1113/jphysiol.1997.sp021881">slows down our digestion</a>. If your body is processing and digesting food instead of focusing all its resources on sleep, this can affect your shut-eye. Research has shown eating close to bedtime <a href="https://doi.org/10.3945/an.116.012336">reduces our sleep quality</a>, particularly our time spent in rapid eye movement (REM) sleep, which is the stage of sleep associated with <a href="https://doi.org/10.1016/j.tics.2009.12.001">vivid dreams</a>. People will have an even harder time digesting cheese at night if they’re lactose intolerant, which might mean they experience even greater impacts on their sleep. This follows what the Canadian researchers found in their study, with lactose intolerant participants reporting poorer sleep quality and more nightmares. It’s important to note we might actually have vivid dreams or nightmares every night – what could change is whether we’re aware of the dreams and can remember them when we wake up. Poor sleep quality often means we wake up more during the night. If we wake up during REM sleep, <a href="https://doi.org/10.1126/science.1063530">research shows</a> we’re more likely to report vivid dreams or nightmares that we mightn’t even remember if we hadn’t woken up during them. This is very relevant for the cheese and nightmares question. Put simply, eating before bed impacts our sleep quality, so we’re more likely to wake up during our nightmares and remember them. <h2>Can I still have brie before bedtime?</h2> Don’t panic – I’m not here to tell you to give up your cheesy evenings. But what we eat before bed can make a real difference to how well we sleep, so timing matters. General <a href="https://www.sleephealthfoundation.org.au/sleep-topics/sleep-hygiene-good-sleep-habits">sleep hygiene guidelines</a> suggest avoiding meals at least two hours before bed. So even if you’re eating a very cheese-heavy meal, you have a window of time before bed to digest the meal and drift off to a nice peaceful sleep. <h2>How about other dairy products?</h2> Cheese isn’t the only dairy product which may influence our sleep. Most of us have heard about the benefits of having a warm glass of milk before bed. Milk can be easier to digest than cheese. In fact, milk is a good choice in the evening, as <a href="https://doi.org/10.3390/nu12040936">it contains tryptophan</a>, an amino acid that helps promote sleep. Nonetheless, we still don’t want to be challenging our body with too much dairy before bed. Participants in the Canadian study did report nightmares after dairy, and milk close to bed might have contributed to this. While it’s wise to steer clear of food (especially cheese) in the two hours before lights out, there’s no need to avoid cheese altogether. Enjoy that cheesy pasta or cheese board, just give your body time to digest before heading off to sleep. If you’re having a late night cheese craving, opt for something small. Your sleep (and your dreams) will thank you.<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/260205/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/charlotte-gupta-347235">Charlotte Gupta</a>, Senior Postdoctoral Research Fellow, Appleton Institute, HealthWise Research Group, <a href="https://theconversation.com/institutions/cquniversity-australia-2140">CQUniversity Australia</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How old are you really? Are the latest ‘biological age’ tests all they’re cracked up to be?

<div class="theconversation-article-body"> We all like to imagine we’re ageing well. Now a simple blood or saliva test promises to tell us by measuring our “<a href="https://www.si.com/soccer/cristiano-ronaldo-shocking-biological-age">biological age</a>”. And then, as many have done, we can <a href="https://nypost.com/2024/07/25/entertainment/khloe-kardashian-40-learns-her-biological-age-is-28/">share</a> how “young” we really are on social media, along with our secrets to success. While chronological age is how long you have been alive, <a href="https://www.medicalnewstoday.com/articles/chronological-aging">measures of biological age</a> aim to indicate how old your body actually is, purporting to measure “wear and tear” at a molecular level. <blockquote class="twitter-tweet"> Cristiano Ronaldo is biologically 29 years old! 😱 CR7’s WHOOP stats put his body at 12 years younger than his actual age! 💪 Cristiano’s dedication to his health and longevity is second to none 👏 (Via <a href="https://twitter.com/Cristiano?ref_src=twsrc%5Etfw">@cristiano</a>/<a href="https://twitter.com/WHOOP?ref_src=twsrc%5Etfw">@WHOOP</a>) <a href="https://t.co/PwKqc77031">pic.twitter.com/PwKqc77031</a> — DAZN Football (@DAZNFootball) <a href="https://twitter.com/DAZNFootball/status/1925894821203321009?ref_src=twsrc%5Etfw">May 23, 2025</a></blockquote> The appeal of these tests is undeniable. Health-conscious consumers may see their results as reinforcing their anti-ageing efforts, or a way to show their journey to better health is paying off. But how good are these tests? Do they actually offer useful insights? Or are they just clever marketing dressed up to look like science? <h2>How do these tests work?</h2> Over time, the chemical processes that allow our body to function, known as our “metabolic activity”, lead to damage and a decline in the activity of our cells, tissues and organs. Biological age tests aim to capture some of these changes, offering a snapshot of how well, or how poorly, we are <a href="https://www.aginganddisease.org/EN/10.14336/AD.2022.1107">ageing on a cellular level</a>. Our DNA is also affected by the ageing process. In particular, chemical tags (methyl groups) attach to our DNA and affect gene expression. These changes occur in predictable ways with age and environmental exposures, in a process called methylation. Research studies have used “epigenetic clocks”, which measure the methylation of our genes, to estimate biological age. By analysing methylation levels at specific sites in the genome from participant samples, researchers apply predictive models to estimate the cumulative wear and tear on the body. <h2>What does the research say about their use?</h2> Although the science is rapidly evolving, the evidence underpinning the use of epigenetic clocks to measure biological ageing in research studies is <a href="https://pubmed.ncbi.nlm.nih.gov/39743988/">strong</a>. Studies have shown epigenetic biological age estimation is a <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC5940111/">better predictor</a> of the risk of death and ageing-related diseases than chronological age. Epigenetic clocks also have been found to <a href="https://www.sciencedirect.com/science/article/pii/S1279770725001277?dgcid=rss_sd_all">correlate strongly</a> with lifestyle and environmental exposures, such as smoking status and diet quality. In addition, they have been found to be able to <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8484046/">predict</a> the risk of conditions such as cardiovascular disease, which can lead to heart attacks and strokes. Taken together, a growing body of research indicates that at a population level, epigenetic clocks are robust measures of biological ageing and are strongly linked to the risk of <a href="https://www.aginganddisease.org/EN/10.14336/AD.2022.1107">disease and death</a> <h2>But how good are these tests for individuals?</h2> While these tests are valuable when studying populations in research settings, using epigenetic clocks to measure the biological age of individuals is a different matter and requires scrutiny. For testing at an individual level, perhaps the most important consideration is the “signal to noise ratio” (or precision) of these tests. This is the question of whether a single sample from an individual may yield widely differing results. A <a href="https://www.nature.com/articles/s43587-022-00248-2">study from 2022</a> found samples deviated by up to nine years. So an identical sample from a 40-year-old may indicate a biological age of as low as 35 years (a cause for celebration) or as high as 44 years (a cause of anxiety). While there have been significant improvements in these tests over the years, there is considerable <a href="https://www.nature.com/articles/s43587-022-00248-2">variability</a> in the precision of these tests between commercial providers. So depending on who you send your sample to, your estimated biological age may vary considerably. <blockquote class="twitter-tweet"> Khloé Kardashian, 40, learns her biological age after confessing bad eating habits <a href="https://t.co/vlipIl9Im2">https://t.co/vlipIl9Im2</a> <a href="https://t.co/s1zRdpht0K">pic.twitter.com/s1zRdpht0K</a> — New York Post (@nypost) <a href="https://twitter.com/nypost/status/1816322940532650399?ref_src=twsrc%5Etfw">July 25, 2024</a></blockquote> Another limitation is there is currently no standardisation of methods for this testing. Commercial providers perform these tests in <a href="https://www.livescience.com/health/ageing/new-biological-aging-test-predicts-your-odds-of-dying-within-the-next-12-months">different ways</a> and have different algorithms for estimating biological age from the data. As you would expect for commercial operators, providers don’t disclose their methods. So it’s difficult to compare companies and determine who provides the most accurate results – and what you’re getting for your money. A third limitation is that while epigenetic clocks correlate well with ageing, they are simply a “<a href="https://frontlinegenomics.com/opinion-direct-to-consumer-epigenetic-tests-are-not-getting-enough-scrutiny/#:%7E:text=Companies%20claim%20that%20epigenetic%20variants,in%20the%20usual%20DTC%20scrutiny">proxy</a>” and are not a diagnostic tool. In other words, they may provide a general indication of ageing at a cellular level. But they don’t offer any specific insights about what the issue may be if someone is found to be “ageing faster” than they would like, or what they’re doing right if they are “ageing well”. So regardless of the result of your test, all you’re likely to get from the commercial provider of an epigenetic test is generic advice about what the science says is healthy behaviour. <h2>Are they worth it? Or what should I do instead?</h2> While companies offering these tests may have good intentions, remember their ultimate goal is to sell you these tests and make a profit. And at a cost of around A$500, they’re not cheap. While the idea of using these tests as a personalised health tool has potential, it is clear that <a href="https://www.theguardian.com/science/2022/jun/13/biological-age-startups-why">we are not there yet</a>. For this to become a reality, tests will need to become more reproducible, standardised across providers, and validated through long-term studies that link changes in biological age to specific behaviours. So while one-off tests of biological age make for impressive social media posts, for most people they represent a significant cost and offer limited real value. The good news is we already know what we need to do to increase our chances of living longer and healthier lives.

"First time I've really cried": Star shares sad family news

Christina Applegate is mourning the loss of her father, Robert "Bob" Applegate, who passed away last week. The 53-year-old actress shared the heartbreaking news during an emotional episode of her podcast MeSsy, which she co-hosts with fellow actress Jamie Lynn Sigler. Applegate broke down in tears as she revealed her father had died just a week earlier, marking the first time she publicly grieved his passing. "You're probably wondering why I'm crying right now, I'm sorry," Applegate said through tears. "My dad just passed away a week ago. This is the first time I've really cried." Struggling to hold back emotion, the Dead to Me star admitted that she had been suppressing her grief. "I think kind of, like, I wasn't allowing myself to have that yet. [I was] too busy with this, too busy with that." Applegate hinted that her father's death followed an illness, though she did not share specific details. “We knew he was going to die," she said. "Is that an excuse for not feeling? Because you know that someone's gonna go, and you've said your goodbyes?” The episode of MeSsy centreed on a conversation about grief with guest JoAnna García Swisher. Sigler, aware of how raw the topic might be, warned that the discussion could be "triggering" for Applegate. At the time, Applegate believed she would be able to handle it – but as the recording unfolded, her sadness surfaced. “I thought I was going to be OK, and I’m not,” she said. “I’m insanely sad.” Christina Applegate, the only child of Bob Applegate and actress Nancy Priddy, has largely kept her family life out of the spotlight. However, she and her father did share a public moment together in 2013 on TLC’s Who Do You Think You Are, exploring their family’s roots. Bob Applegate’s passing comes during an already difficult chapter in Christina’s life. In 2021, she was diagnosed with Multiple Sclerosis (MS). She has spoken candidly about her battle with the illness, revealing on a recent episode of Dax Shepard's Armchair Expert that she has “30 lesions” on her brain. “My biggest one is behind my right eye, so my right eye hurts a lot,” she shared.

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.

Do natural fabrics really keep us cooler in summer? Here’s the science

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/nisa-salim-1442233">Nisa Salim</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a> The Bureau of Meteorology has warned Australia is facing one of the <a href="https://www.abc.net.au/news/2024-10-12/australia-facing-one-of-hottest-summers-on-record-bom/104464014">hottest summers on record</a>. As the weather warms, many of us reach for light-coloured clothes in natural fabrics, such as cotton and linen. But why are natural fabrics like these so much better at keeping us cool when the weather is hot? Here’s what the science says. <h2>Natural fabrics and sweat: a match made in heaven</h2> In hot weather, we sweat. As sweat evaporates, it carries heat away, which helps cool the body down. In hot weather, then, we want clothes that help take moisture away from the body as efficiently as possible. Natural fabrics are made using fibres extracted from plant- or animal-based sources such as cotton, linen, hemp, wool and silk. The primary component of all plant-based fibres is cellulose. Animal-based fibres are made up of proteins such as keratin and silk fibroin. Cellulose molecules are rich in compounds called hydroxyl groups that attract water and moisture. In scientific terms, they are hydrophilic – they love water. So, clothing made of cotton and linen is highly hydrophilic. It tends to absorb moisture and disperse it across the fabric, allowing it to evaporate more easily. This takes the sweat away quickly, making it more comfortable and breathable and allowing us to stay cool in sweltering temperatures. One downside of the natural fabrics is they wrinkle quickly (some people, of course, like that look). And on a really hot, sweaty day, natural fabrics can get heavy and wet. Animal fibres are basically proteins, and their properties vary depending on the source. Wool has been bio-engineered over millions of years to be comfortable to wear. Wool fibres are hydrophilic on the inside and hydrophobic on the outside, meaning they’re both water resistant and good at wicking moisture away. On the other hand, silk fabrics are very good at helping regulate temperature; they keep us cool in hot weather and warm in cold weather. <h2>Synthetic fabrics: less wrinkly, more sweaty</h2> Synthetic fabrics, on the other hand, are lighter and tend to wrinkle less. Common synthetic fabrics (such as polyester, nylon and acrylic) are all made from petroleum-based chemicals. Most synthetic fibres are made of long chains of hydrogen and carbon atoms and do not contain the hydroxyl groups we discussed earlier. Such fibres are therefore hydrophobic – they hate water. This means the water can’t spread evenly across the fabric and evaporate easily. They trap sweat against the skin, making the clothes less breathable and comfortable when the weather is warm and humid. However, some synthetic fabrics used in certain types of active wear can wick sweat away from body. And some semi-synthetic fabrics such as rayon or tencel (which are made from wood pulp or cotton with synthetic fibres) are more breathable than other synthetic fabrics such as polyester or nylon. <h2>Fabric weave makes a difference, too</h2> The colour of the clothing is also a contributing factor to keep you cool during summer. Light colours reflect sunlight away from you and help to keep the body cooler. There is some evidence dark colours absorb the <a href="https://www.sciencedirect.com/science/article/pii/S2214157X23012054">sunlight and associated heat</a>, making the surface of the skin warmer than normal. Another factor affecting breathability and comfort of clothing is the way the fabrics are woven. Fabrics that are loosely woven (sometimes known as “open weave”) with thinner materials naturally have more airflow, which helps you keep cool. For a quick, non-scientific test, hold a fabric up and see how much light passes through it. The more light you can see, the more breathable it likely is. The way the fabric is treated can play a role, too; such as for softening and wrinkle resistance. Using a fabric softener when you do a load of laundry usually doesn’t affect fabric breathability; softeners modify the surface of the fabric but don’t change the internal structure or porous nature of the fabrics. Wrinkle resistance is the ability of the fabric to stay smooth and polished even after washing. Synthetic fabrics are inherently wrinkle resistant. Natural fibres are more prone to wrinkles but can be chemically treated on the fabric surface during manufacturing to make them wrinkle resistant. Such treatments, however, may form layers on top of the fabric blocking the airflow, leading them to be less breathable.<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/240909/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/nisa-salim-1442233">Nisa Salim</a>, Senior Lecturer at the School of Engineering, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

When a casual punt turns into addictive gambling – how to ensure it won’t really cost you

Gambling is a real and growing problem. Left unchecked, the occasional punt can quickly develop into an addiction, with devastating effects on finances and relationships. Debts can spiral and the stress causes marriages to fail and other relationships to splinter. <a href="https://www.monash.edu/medicine/news/latest/2022-articles/gambling-and-homelessness-a-growing-problem-amongst-older-australians">Research published in 2022 by Monash University</a> also found that gambling and homelessness are “interconnected”, singling out senior Australians as most in the firing line. Before things devolve to that level, consider these steps for putting boundaries around your – or your partner’s – gambling. Remember: Big business is big for a reason In 2023, the <a href="https://www.aihw.gov.au/reports/australias-welfare/gambling">Australian Institute of Health and Welfare (AIHW)</a> noted that “Australians lose approximately $25 billion on legal forms of gambling each year, representing the largest per capita losses in the world”. That equates to every single Aussie losing $909 annually. The reality is these companies exist to make money – and skew the odds in their favour, not yours. Keep that in mind the next time you’re tempted to try your “luck”. Stay active For some people, especially retirees, gambling becomes something to pass the time and get them out of the house. However, you needn’t gamble your money away to keep boredom at bay. There are healthier and more productive ways to do this. For example, there are a myriad of social, sporting, and recreational groups for seniors and retirees. A lack of work commitments offers the flexibility to indulge in travel, both within Australia and overseas. Take the opportunity to socialise with friends and family. Turn your hobby or side hustle into a proper business. Or get a dog you can take for long walks. The possibilities are endless… Don’t punt with what you can’t afford to lose Gambling with a bit of money you have specifically put aside for leisure activities is one thing; gambling your life savings or money needed for essentials like food, bills and keeping a roof over your head is quite another. Having lost that essential money, problem gamblers often become desperate to try and win it back – begging, borrowing or even stealing more, with the repercussions quickly spiralling out of control as that money is often lost too. If you must gamble, only gamble what you can afford to lose: have a budgeted amount and stick to it no matter what. Anyone who deep-down knows they aren’t disciplined with their money would be wise to think twice altogether. Never borrow to gamble As a rule of thumb, money that comes with a cost attached to it should only ever be spent on things that will make more money in the long run, like buying a home or investing. When it comes to gambling, always use your free cash. Money you have borrowed, redrawn from your home loan, or racked up on your credit card will have to be repaid eventually – with interest on top. Choose a place and a time “Most people using gambling machines are older Australians,” <a href="https://www.monash.edu/medicine/news/latest/2022-articles/gambling-and-homelessness-a-growing-problem-amongst-older-australians">Monash University’s Associate Professor Charles Livingstone says</a>. This type of gambling is where things can easily turn sinister. To help keep things in check, limit your gambling to special occasions or events. That might be a flutter on the Melbourne Cup, a game of two-up on ANZAC Day, or a Lotto ticket as a birthday treat. It will mean more if it is tied to something special and an experience you can share with loved ones. Which leads into our next point: Avoid gambling alone Gambling by yourself can be a recipe for disaster. You don’t have a second pair of eyes over what you are doing or that trusted person to step in and say, ‘that’s enough’. In fact, I recommend couples always take a joint approach to their finances, regardless of whether gambling is involved. Leaving all the “money stuff” up to one of you means less accountability and opens the door for shared money and assets to be used improperly. Ask for help If you recognise things are getting out of hand, don’t suffer in silence. Talk things through with your partner, adult children or a trusted friend.

The anatomy of a hot flush – and whether it can really make your head steam

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/michelle-spear-172043">Michelle Spear</a>, <a href="https://theconversation.com/institutions/university-of-bristol-1211">University of Bristol</a> A hot flush is a phenomenon as disruptive as it is commonplace. One moment, life proceeds as usual. The next, a wave of heat rises, spreading from the chest to the face – leaving behind flushed skin and beads of sweat. For many, this sudden warmth is accompanied by an <a href="https://www.mayoclinic.org/diseases-conditions/hot-flashes/symptoms-causes/syc-20352790">accelerated heartbeat and a faint sense of unease</a>. Though brief – typically lasting anywhere from 30 seconds to five minutes – its intensity can be startling and made worse by unpredictable timing. A recent viral video has brought attention to just how intense a hot flush can be. The video depicts a woman named Tracey Monique <a href="https://uk.style.yahoo.com/menopause-hot-flush-flash-symptoms-134536113.html?guccounter=1">experiencing a hot flush</a> while at an outdoor event. In the video, her head is literally steaming. The sight of wisps of vapour escaping her head highlighted the dramatic effects of this common <a href="https://www.nhs.uk/conditions/menopause/symptoms/">perimenopausal symptom</a>. Often misunderstood or trivialised, the image of a hot flush brings fresh attention to a phenomenon that affects an estimated <a href="https://www.hopkinsmedicine.org/health/conditions-and-diseases/introduction-to-menopause">75% of people experiencing perimenopause</a>. The video has also sparked debate on social media – reflecting the complexity of hot flushes themselves. Some argue the steam escaping Monique’s head was caused by her removing her hat while being in the cold. But many women have commented, saying the video perfectly encapsulates what a hot flush feels like. Let’s take a look at what’s actually happening during a hot flush and why they can feel so severe. <h2>Hormonal instigators</h2> At the heart of a hot flush lies oestrogen – a hormone critical role in regulating body temperature in women. Oestrogen directly <a href="https://my.clevelandclinic.org/health/body/22566-hypothalamus">influences the hypothalamus</a>, a small but essential structure in the brain often referred to as the <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6397692/">body’s thermostat</a>. The hypothalamus monitors and adjusts body temperature to maintain balance. Under normal circumstances, the hypothalamus keeps the body within a narrow temperature range – adjusting blood flow and sweat production as needed. But during perimenopause, <a href="https://www.rcog.org.uk/for-the-public/browse-our-patient-information/treatment-for-symptoms-of-the-menopause/?utm_source=chatgpt.com">oestrogen levels fluctuate</a> unpredictably and eventually decline. These hormonal shifts disrupt the hypothalamus’s ability to maintain its usual set temperature. Declining oestrogen levels also make the hypothalamus overly sensitive to small changes in body temperature – misinterpreting these as <a href="https://pubmed.ncbi.nlm.nih.gov/31001050/">signs of overheating</a>. This triggers an exaggerated response aimed at cooling the body down: a hot flush. The result is a sudden dilation of blood vessels, particularly in the skin of the upper body, to allow heat to radiate outward. Simultaneously, sweat glands activate – intensifying the sensation of heat. <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC3956631/">Luteinising hormone</a>, which primarily regulates ovulation, also plays a secondary role in hot flushes. As oestrogen levels decline, the pituitary gland (which regulates key hormones that control growth, reproduction and metabolism) <a href="https://academic.oup.com/endo/article/163/2/bqab268/6490154">releases erratic surges</a> of lutenising hormone. These spikes appear to further heighten the hypothalamus’s sensitivity, amplifying its misinterpretation of normal body temperature as overheating. <h2>The cooling response</h2> During a hot flush the hypothalamus sends urgent signals to the autonomic nervous system, which governs involuntary functions such as heart rate, blood pressure and sweating. This prompts blood vessels near the skin to dilate – a <a href="https://www.ncbi.nlm.nih.gov/books/NBK557562/">process called vasodilation</a>. This allows more blood to flow to the surface to release heat. This is why the face, neck and chest can feel intensely warm and look visibly flushed during a hot flush. Almost simultaneously, the hypothalamus activates sweat glands in the upper body. Sweating is meant to <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6773238/">cool the body</a> through evaporation. In cold environments, this sweat may produce visible steam – as seen in Monique’s viral video. But once the hypothalamus realises the body isn’t actually overheated, vasodilation subsides and blood vessels return to their normal state. But the rapid cooling effect from sweating can leave women <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4612529/">feeling chilled</a>. This creates a rollercoaster of sensations during and after the hot flush. This sequence – heat, flush, sweat and chill – reflects the body’s struggle to regain equilibrium in response to a misfiring thermostat. <h2>The debate</h2> While the sensation of heat is undeniable, whether hot flushes significantly raise skin temperature remains debated. <a href="https://www.maturitas.org/article/0378-5122(79)90009-4/abstract">Thermographic studies</a>, which use infrared imaging to measure heat patterns and surface temperature, have demonstrated measurable skin temperature rises – particularly in the face, neck and chest. But other research has found only <a href="https://www.obgproject.com/2019/07/24/are-menopausal-hot-flushes-really-triggered-by-core-temperature/">minor or negligible changes</a> in skin temperature. This raises questions about whether the perception of heat correlates directly with physiological changes. Critics suggest that the sensation of heat stems more from the brain’s altered thermoregulation than from actual warming of the skin. Tools such as thermographic imaging may also miss subtle or transient temperature changes – or these changes may be masked by sweat evaporation. It may also be the case that <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4612529/">skin temperature changes</a>, like other perimenopausal symptoms, vary widely between people. The <a href="https://bmcwomenshealth.biomedcentral.com/articles/10.1186/1472-6874-9-13">variability in oestrogen levels</a> contributes significantly – with those experiencing more erratic hormonal changes often reporting more intense or frequent flushes. Factors such as <a href="https://www.mdpi.com/2072-6643/16/5/655">genetics, lifestyle and environmental triggers</a>, all add to the diversity of experiences and how intense symptoms might be. Hot flushes are a complex interplay of hormonal, neurological and vascular responses. While the scientific debate about skin temperature changes remains unresolved, the lived experience of heat and discomfort is undeniable. For many, these symptoms are disruptive and even debilitating, profoundly affecting daily life. Monique’s viral video, with the striking image of steam rising from her head, has resonated deeply with countless women – offering stark visual evidence of what they’ve felt but often struggled to articulate. Understanding the anatomy of a hot flush not only sheds light on its mechanisms but also underscores the importance of empathy and tailored approaches to managing this multifaceted symptom.<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/244452/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/michelle-spear-172043">Michelle Spear</a>, Professor of Anatomy, <a href="https://theconversation.com/institutions/university-of-bristol-1211">University of Bristol</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"That's really spot on": Robert Irwin's tearful reaction to seeing his dad's wax figure

Robert Irwin has made history as the youngest Australian ever to be immortalised in wax at Madame Tussauds Sydney. The 20-year-old conservationist unveiled his lifelike figure in an emotional ceremony today, which also marked his first encounter with the wax figure of his late father, Steve Irwin. Dressed in his iconic Australia Zoo khakis, Robert’s wax figure radiates his adventurous spirit, holding a Canon DSLR camera while a python drapes over the lens – a fitting tribute to his passion for wildlife photography and conservation. Sharing the milestone on social media, Irwin posted, “Caught up with my new mate today at Madame Tussaud’s Sydney… So SURREAL and such an honour! Grateful 🙏.” Speaking with Sunrise, Robert also reflected on the poignant moment of seeing his father’s wax figure in person for the first time. “It was the first time I’d ever got to see my dad’s wax figure. I’d seen pictures of it, but I’d never seen it in real life, and I was actually, I was overcome with emotion and I didn’t think that was going to happen,” he said. <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/p/DC5Rk1xTC_v/?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/p/DC5Rk1xTC_v/?utm_source=ig_embed&utm_campaign=loading" target="_blank" rel="noopener">A post shared by Robert Irwin (@robertirwinphotography)</a> </div> </blockquote> Steve Irwin, the beloved “Crocodile Hunter” passed away in 2006, leaving behind a legacy of conservation and education.

What does a good death look like when you’re really old and ready to go?

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/naomi-richards-182120">Naomi Richards</a>, <a href="https://theconversation.com/institutions/university-of-glasgow-1269">University of Glasgow</a> <a href="https://www.huffingtonpost.co.uk/entry/hawaii-legalizes-assisted-suicide_us_5ac6c6f5e4b0337ad1e621fb">Hawaii</a> recently joined the growing number of states and countries where doctor-assisted dying is legal. In these jurisdictions, help to die is rarely extended to those who don’t have a terminal illness. Yet, increasingly, very old people, without a terminal illness, who feel that they have lived too long, are arguing that they also have a right to such assistance. Media coverage of <a href="https://www.washingtonpost.com/news/to-your-health/wp/2018/05/09/this-104-year-old-plans-to-die-tomorrow-and-hopes-to-change-views-on-assisted-suicide/?utm_term=.b00a9036f9bc">David Goodall</a>, the 104-year-old Australian scientist who travelled to Switzerland for assisted dying, demonstrates the level of public interest in ethical dilemmas at the <a href="https://www.bmj.com/content/361/bmj.k1891.full">extremities of life</a>. Goodall wanted to die because he no longer enjoyed life. Shortly before his death, he told reporters that he spends most of his day just sitting. “What’s the use of that?” he asked. <a href="https://www.sciencedirect.com/science/article/pii/S0277953615002889?via%3Dihub">Research</a> shows that life can be a constant struggle for the very old, with social connections hard to sustain and health increasingly fragile. <a href="https://www.ncbi.nlm.nih.gov/pubmed/25982088">Studies</a> looking specifically at the motivation for assisted dying among the very old show that many feel a deep sense of loneliness, tiredness, an inability to express their individuality by taking part in activities that are important to them, and a hatred of dependency. Of the jurisdictions where assisted dying is legal, some make suffering the determinant (Canada, for example). Others require a prognosis of six months (California, for example). Mainly, though, the focus is on people who have a terminal illness because it is seen as less of an ethical problem to hasten the death of someone who is already dying than someone who is simply tired of life. <h2>Why give precedence to physical suffering?</h2> Assisted dying for people with psychological or existential reasons for wanting to end their life is unlikely to be supported by doctors because it is not objectively verifiable and also potentially remediable. In the Netherlands, despite the legal power to offer assistance where there is no life-limiting illness, doctors are <a href="https://www.ncbi.nlm.nih.gov/pubmed/25693947">seldom convinced</a> of the unbearable nature of non-physical suffering, and so will rarely administer a lethal dose in such cases. Although doctors may look to a physical diagnosis to give them confidence in their decision to hasten a patient’s death, physical symptoms are often not mentioned by the people they are assisting. Instead, the most common reason given by those who have received help to die is <a href="https://www.nejm.org/doi/full/10.1056/NEJMms1700606">loss of autonomy</a>. Other common reasons are to avoid burdening others and not being able to enjoy one’s life – the exact same reason given by Goodall. This suggests that requests from people with terminal illness, and from those who are just very old and ready to go, are not as different as both the law – and doctors’ interpretation of the law – claim them to be. <h2>Sympathetic coverage</h2> It seems that the general public does not draw a clear distinction either. Most of the media coverage of Goodall’s journey to Switzerland was sympathetic, to the dismay of <a href="http://www.carenotkilling.org.uk/press-releases/centenarians-assisted-suicide/">opponents</a> of assisted dying. Media reports about <a href="https://www.theguardian.com/tv-and-radio/2014/sep/02/mary-berry-great-british-bake-off-centenarian-assisted-dying">ageing celebrities</a> endorsing assisted dying in cases of both terminal illness and very old age, blur the distinction still further. One of the reasons for this categorical confusion is that, at root, this debate is about what a good death looks like, and this doesn’t rely on prognosis; it relies on <a href="https://www.tandfonline.com/doi/full/10.1080/01459740.2016.1255610">personality</a>. And, it’s worth remembering, the personalities of the very old are as diverse as those of the very young. Discussion of assisted suicide often focuses on concerns that some older people may be exposed to coercion by carers or family members. But older people also play another role in this debate. They make up the rank and file <a href="http://www.ep.liu.se/ej/ijal/2012/v7/i1/a01/ijal12v7i1a01.pdf">activists</a> of the global right-to-die movement. In this conflict of rights, protectionist impulses conflict with these older activists’ demands to die on their own terms and at a time of their own choosing. In light of the <a href="https://www.nih.gov/news-events/news-releases/worlds-older-population-grows-dramatically">unprecedented ageing</a> of the world’s population and increasing longevity, it is important to think about what a good death looks like in deep old age. In an era when more jurisdictions are passing laws to permit doctor-assisted dying, the choreographed death of a 104-year-old, who died listening to Ode to Joy after enjoying a last fish supper, starts to look like a socially approved good death.<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/96589/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/naomi-richards-182120">Naomi Richards</a>, Lecturer in Social Science (End of Life Studies), <a href="https://theconversation.com/institutions/university-of-glasgow-1269">University of Glasgow</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How are racehorses really treated in the ‘sport of kings’?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/cathrynne-henshall-572585">Cathrynne Henshall</a>, <a href="https://theconversation.com/institutions/charles-sturt-university-849">Charles Sturt University</a> It’s the time of year when shiny horses and colourful clothing fill our screens – the <a href="https://www.racing.com/spring-racing">Spring Racing Carnival</a>, which includes high profile races like The Everest, Melbourne Cup and Cox Plate. It’s also the time of year when questions are asked about the welfare of racehorses that compete in the so-called “<a href="https://www.amnh.org/exhibitions/horse/how-we-shaped-horses-how-horses-shaped-us/sport/sport-of-kings#:%7E:text=Thoroughbred%20racing%20began%20around%20300,Asia%2C%20and%20the%20Middle%20East.">sport of kings</a>”. Previously, <a href="https://www.news.com.au/sport/superracing/punters-life/how-many-horses-have-died-in-the-melbourne-cup-the-real-numbers/news-story/5f7e29011a7fbf3da9e0611e902d1ee6">high profile deaths during races</a>, the <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0015622">use of whips</a> and <a href="https://www.abc.net.au/news/2015-02-17/making-a-killing/6127124">what happens to horses after racing</a> have been the focus of community concern. But recently, as we’ve come to know more about what makes a <a href="https://www.worldhorsewelfare.org/advice/welfare-wednesdays/how-to-provide-a-good-life-for-horses-friends-freedom-and-forage">good life for a horse</a>, questions are being raised about the daily lives of racehorses. Industry participants will point to the <a href="https://www.mamamia.com.au/dont-tell-me-the-horse-racing-industry-doesnt-care/">high level care</a> that racehorses receive – comfortable stables, specially formulated diets, the latest vet treatments and added extras such as massages and swimming sessions. But does this care translate into good welfare? <h2>The theory of ‘telos’</h2> Firstly, a quick primer on the difference between care and welfare. Care includes all the things that make sure racehorses get fit, stay fit and stay healthy. This care helps maximise the chance a horse will win races. Welfare is the animal’s subjective or individual experience of its life – <a href="https://pubmed.ncbi.nlm.nih.gov/33066335/">how it feels</a> – and there are a number of ways to assess this. One way is the concept of “telos”, originally developed by Ancient Greek philosopher <a href="https://plato.stanford.edu/entries/aristotle-causality/">Aristotle</a>. Telos is a <a href="https://link.springer.com/article/10.1007/s10806-012-9422-y">species’ anatomical, physiological, behavioural and cognitive characteristics</a> that have been shaped by millions of years of evolution. Telos helps us to identify what matters to animals – their behavioural, psychological and physiological needs. So to consider if racehorse care actually translates to good welfare, we can assess how closely it provides the animal with the things that matter to them, based on their telos. Equine telos involves living in groups, forming long-lived social relationships, grazing fibrous plants and being on the move for up to 18 hours a day, as well as staying safe by sensing danger and then moving away. It also involves living in variable environments to solve challenges, learn, engage in curiosity and play. Let’s compare that to the daily life of a racehorse. <h2>Movement and feeding</h2> Firstly, the vast majority of racehorses live in stables – sometimes up to 23 hours a day. <a href="https://pubmed.ncbi.nlm.nih.gov/17970632/">Multiple studies</a> have found continuous stabling harms horse welfare. Stables significantly restrict opportunities for voluntary movement, and studies show stabled horses spend <a href="https://pubmed.ncbi.nlm.nih.gov/37813129/">the majority of the time inactive</a>. Even though stables house horses communally, most designs limit horses’ opportunities for social interaction. Thirdly, there’s little for a horse to do in a stable other than eat, stand, drink or lie, and they often develop <a href="https://pubmed.ncbi.nlm.nih.gov/34670688/">abnormal behaviours</a> that are associated with stress. These are never seen in free-ranging horses. When racehorses do get to move, they have little say over how far, how fast and for how long they move. The kinds of physical exercise racehorses do are both significantly shorter in duration and at much higher speeds than horses voluntarily choose. It’s those speeds that place them at <a href="https://pubmed.ncbi.nlm.nih.gov/17910268/">risk of suffering a serious injury</a>. What about diet? Although a lot of time and effort is spent ensuring racehorses enjoy high quality diets, they are mostly comprised of concentrated energy sources such as grains, rather the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10135103/">fibre horses evolved to eat</a>. Horses are <a href="https://madbarn.com/slow-feeders-for-horses/#:%7E:text=Horses%20are%20trickle%20feeders%20that,to%2025%20miles%20per%20day.">trickle feeders</a> (grazers), with small stomachs that continuously secrete digestive juices. In the wild, grazing keeps those stomachs full, which prevents the stomach lining from being damaged by digestive acids. In comparison, racehorses often consume their food very quickly – instead of spending up to 75% of their day eating, <a href="https://www.sciencedirect.com/science/article/pii/B9780702026348500137">they spend only 33%</a>. This means their stomachs are empty for most of the day, which is why up to <a href="https://pubmed.ncbi.nlm.nih.gov/37048517/">65% will get painful gastric ulcers</a>. And having to wait to be fed rather than eating when hungry, as happens in free-ranging horses, <a href="https://www.mdpi.com/2076-2615/3/3/663">can lead to frustration</a>. <h2>Other difficulties</h2> Racehorses <a href="https://www.theage.com.au/national/does-whipping-hurt-race-horses-20211102-p595br.html">may be whipped</a>, and <a href="https://beva.onlinelibrary.wiley.com/doi/10.1111/j.2042-3306.1982.tb02389.x">more than 50% </a> will experience some form of musculoskeletal injury during racing, of which between <a href="https://www.mdpi.com/2076-2615/11/2/270">7-49% are fatal</a>. Social relationships, in the limited form possible in a racing stable, are also frequently disrupted because horse populations are highly transient due to spelling, <a href="https://theconversation.com/black-caviars-death-has-prompted-uncomfortable-questions-about-how-champion-mares-spend-their-retirement-237039">retirement</a> or even just going to the races. So even if two horses are able to form a relationship of sorts, chances are one will be taken away. <a href="https://pubmed.ncbi.nlm.nih.gov/?term=henshall+stress+repeated&size=200">Separation distress is a significant stressor</a> for horses. Then there’s the gear that’s used to control them. Horses, like most animal species, escape and avoid painful stimuli. However, in racing (and many other equestrian activties) it is <a href="https://www.racingnsw.com.au/wp-content/uploads/NSWRules.pdf">mandatory to use</a> “bits” to control horses’ behaviour during riding and handling. Bits work by causing uncomfortable pressure and pain and may lead to mouth injuries. Studies have shown many people don’t understand how <a href="https://www.tandfonline.com/doi/full/10.1080/08927936.2023.2166713#abstract">to minimise the harm they can cause</a>. In addition, people also vary widely in their ability to read and <a href="https://www.mdpi.com/2076-2615/9/12/1124">interpret behavioural responses to stress</a>. So, racehorses may be repeatedly exposed to pain from bits and perform a range of behaviours to try to escape that pain, like bolting, mouth opening or head tossing. To remedy this, additional items of restrictive equipment, such as <a href="https://pubmed.ncbi.nlm.nih.gov/34056705/">tongue ties</a>, <a href="https://theconversation.com/dressing-up-for-melbourne-cup-day-from-a-racehorse-point-of-view-104771">nosebands, lugging bits or bit burs</a> may be used to control the horse. Racehorses frequently show signs of difficulty coping with the stressors of racing life, including “going off their feed”, aggression towards handlers, becoming hard to control when ridden and a range of stress behaviours and health issues, <a href="https://avmajournals.avma.org/downloadpdf/view/journals/javma/260/15/javma.22.08.0358.pdf">such as bleeding from the lungs</a>. <h2>What about welfare?</h2> Racehorse care is often directed towards managing issues that are the direct result of the demands of the racing environment. Fancy stables and aqua sessions are not important to horses, and may even cause harm. What matters to horses are opportunities to make meaningful choices, such as the freedom to move, form friendships and graze for the majority of the day. Current racing industry practices often deny horses the chance to make these choices. There’s no doubt people in racing care deeply about their horses. But to experience good welfare during racing, racehorses need more than just good care.<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/240998/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/cathrynne-henshall-572585">Cathrynne Henshall</a>, Post-doctoral Fellow, School of Agricultural, Environmental and Veterinary Sciences, <a href="https://theconversation.com/institutions/charles-sturt-university-849">Charles Sturt University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

“Is it really that bad?”: New mum slammed for baby name choice

One woman has taken to social media to explain her dilemma after people around her made her second-guess the name she and her husband chose for their unborn son. The woman shared her situation on Reddit, and explained that the name has a special family significance to her, but so far people around her have absolutely hated it. "My grandpa was my favourite person in the whole world. Growing up, I always loved his name because I thought it was unique and I loved him. I always said if I had a son I would name him after my grandpa," she explained in the post. "Now I'm pregnant, and the very few people I've told the name to HATE IT. The name is Earl. Is it really that bad?" She added that she doesn't want her son to grow up hating his name, but she still wants to use it as it is so special to her. "Few other things: husband is on board and loves it, and it does sound really nice with our last name," she added. Many of the commenters urged her to go with the name if she loves it and to disregard what anyone else says. "This. Is. Your. Baby You don't need to poll the audience or tell anyone the baby's name before he is born. Protect your peace, and Earl's," replied one person. "I love Earl! Easy to say and spell. Uncommon but not made up. The emotional connection is wonderful too!" commented another. "It's a lovely name!!! Don't let other people shame you out of using it because you'll regret listening to them later," a third person assured her. "Earl is dated and country but it's cute and it means something to you and you both love it. It will be fine," another woman said. Some suggested that if she was really struggling with the name after the hate she received, there are other ways to incorporate it. "It's extremely dated but not bad. I personally think it's better as a middle name," replied one person. Image: Shutterstock

Does eating ham, bacon and beef really increase your risk of developing type 2 diabetes?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/duane-mellor-136502">Duane Mellor</a>, <a href="https://theconversation.com/institutions/aston-university-1107">Aston University</a> That lunchtime staple, the humble ham sandwich, has come in for a bashing in the press recently. According to <a href="https://www.theguardian.com/society/article/2024/aug/20/two-slices-of-ham-a-day-can-raise-type-2-diabetes-risk-by-15-research-suggests">many</a> <a href="https://www.dailymail.co.uk/health/article-13761253/Eating-ham-daily-linked-increase-risk-diabetes.html">reports</a>, eating two slices of ham a day can increase your risk of developing type 2 diabetes. But what’s the science behind these headlines? The research offers a more complex picture. <a href="https://www.thelancet.com/journals/landia/article/PIIS2213-8587(24)00179-7/fulltext">A new study</a> from the University of Cambridge highlighted an association between developing type 2 diabetes and eating processed meat like ham and bacon, and red meat such as beef and lamb. This led to headlines suggesting the risk was mainly linked to <a href="https://www.telegraph.co.uk/news/2024/08/21/ham-sandwich-processed-meat-fresh-risk-link-type-2-diabetes/">ham sandwiches</a>. This seems to have come from the <a href="https://www.cam.ac.uk/research/news/red-and-processed-meat-consumption-associated-with-higher-type-2-diabetes-risk">press release</a>, which used ham as the example to quantify the amount of processed meat associated with a 15% increased risk of developing type 2 diabetes over ten years. The research found that this risk was linked to eating an extra 50g of processed meat every day, which happens to equate to two slices of ham. A useful example thus appears to have been taken up by the media as the main cause, perhaps ignoring some of the key messages coming from the study. So, can processed and red meat really increase your risk of developing type 2 diabetes? The <a href="https://www.diabetes.org.uk/diabetes-the-basics/types-of-diabetes/type-2/diabetes-risk-factors">biggest risk factors</a> linked to developing type 2 diabetes are being over 40, having family members with type 2 diabetes, being of South Asian or African descent, or having a higher body weight – and especially a larger waist. <figure><iframe src="https://www.youtube.com/embed/EsOBcx2bJqU?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> The Cambridge study used data from nearly 2 million people from 31 studies. Participants were followed for an average of ten years. During this time, around one in 20 people developed type 2 diabetes. The research suggested that a 10% increase in the probability of developing type 2 diabetes was associated with every 100g of additional red meat eaten daily. Eating half as much extra processed meat every day was linked to an even greater increased risk of developing the disease. This is not the <a href="https://ajcn.nutrition.org/article/S0002-9165(23)66119-2/abstract">first time</a> that both processed and red meats have been linked with an increased risk of developing type 2 diabetes. However, the key strength of the Cambridge study was that it tried to control for many of the other factors linked to the disease, including smoking, having a higher body weight, dietary intake and exercise. However, the size of the increased risk is modest, considering few people included in the study ate 50g or more processed meat per day – meaning moderate ham consumption is likely to have <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9908545/">no meaningful effect</a> on your risk. <h2>What’s the link?</h2> Processed meat has been linked to increased risk of type 2 diabetes because of its nitrate and salt content – additives that are used to cure many processed meats. Nitrates and salt in processed meats have also <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6893523/">been linked to</a> an increased risk of developing colon cancer. In fact, the World Health Organization classifies the additives as <a href="https://www.who.int/news-room/questions-and-answers/item/cancer-carcinogenicity-of-the-consumption-of-red-meat-and-processed-meat">group 1 carcinogens</a>, which means they can cause a range of cancers. The mechanism linking processed meat to cancer seems to be similar to how it might be linked to type 2 diabetes. During digestion, processed meat produces <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6294997/">N-nitroso chemicals</a>, which can damage cells. This can lead to inflammation and affects how insulin, the hormone that controls blood glucose (sugar), works. This in turn can lead to <a href="https://www.niddk.nih.gov/health-information/diabetes/overview/what-is-diabetes/prediabetes-insulin-resistance">insulin resistance</a>, when cells in your muscles, fat and liver don’t respond well to insulin and can’t easily take up glucose from your blood. Red meat, meanwhile, is <a href="https://www.healthline.com/nutrition/healthy-iron-rich-foods">rich in iron</a>. Research suggests that people with <a href="https://www.diabetes.org.uk/diabetes-the-basics/related-conditions/haemochromatosis-diabetes#:%7E:text=So%20a%20rise%20of%20iron,GP%20as%20soon%20as%20possible.">high levels of iron</a> are more likely to develop type 2 diabetes. However, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8744124/#:%7E:text=The%20WHO%20has%20recognised%20iron,being%20affected%20with%20this%20condition.">low levels of iron</a> are more of a health concern for the general population. Another potential link regarding red meat could be the way it is cooked. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5521980/">Previous studies</a> have suggested that charred meat, cooked over an open flame or at high temperature, is also linked to an increased risk of developing <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5911789/">type 2 diabetes</a>. Charring meat leads to formation of toxic chemicals such as <a href="https://www.sciencedirect.com/topics/pharmacology-toxicology-and-pharmaceutical-science/heterocyclic-amine#:%7E:text=Heterocyclic%20amines%20are%20aromatic%20compounds,of%20reactions%20called%20Maillard%20reactions.">heterocyclic aromatic amines</a> and harmful compounds like <a href="https://www.healthline.com/nutrition/advanced-glycation-end-products">advanced glycation end products</a>, both of which have been linked to <a href="https://pubmed.ncbi.nlm.nih.gov/21709297/">insulin resistance and type 2 diabetes</a>. <h2>Bye-bye barbecues and bacon butties?</h2> The key message is reduction, rather than avoidance. The UK government nutritional recommendations offer sound advice: limit your combined intake of red and processed meat to no more than <a href="https://www.nhs.uk/live-well/eat-well/food-types/meat-nutrition/#:%7E:text=Red%20meat%20and%20processed%20meat&text=If%20you%20currently%20eat%20more,%2C%20veal%2C%20venison%20and%20goat.">an average of 70g per day</a>. But these guidelines also suggest that red meat can be a valuable source of iron. So, if you decide to stop eating red meat, you should eat alternative sources of iron such as beans, lentils, dark green vegetables and fortified cereals. This needs to be done as part of a carefully planned diet. Non-meat sources of iron are more difficult for our bodies to absorb so should be eaten with a source of vitamin C, found in green vegetables and citrus fruit. The best advice to reduce your risk of developing type 2 diabetes is to maintain a healthy weight – consider losing weight if you have a higher body weight – and be as physically active as possible. A healthy diet should be based on plenty of vegetables, fruit, beans, peas, lentils, nuts and seeds, along with some wholegrain foods, some dairy products, fish and white meat (or vegetarian alternatives) – plus moderate amounts of red meat and minimal processed meat. This will help reduce your risk of type 2 diabetes, <a href="https://www.bhf.org.uk/informationsupport/support/healthy-living/healthy-eating">heart disease</a>, and <a href="https://www.cancerresearchuk.org/about-cancer/causes-of-cancer/diet-and-cancer/does-having-a-healthy-diet-reduce-my-risk-of-cancer">many cancers</a> – as well being more <a href="https://www.bda.uk.com/static/539e2268-7991-4d24-b9ee867c1b2808fc/a1283104-a0dd-476b-bda723452ae93870/one%20blue%20dot%20reference%20guide.pdf">environmentally sustainable</a>. But if you have a penchant for ham sandwiches, rest assured you can continue to indulge as an occasional treat. It’s your overall lifestyle and diet that really matter for your health and risk of developing type 2 diabetes.<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/237346/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/duane-mellor-136502">Duane Mellor</a>, Visiting Academic, Aston Medical School, <a href="https://theconversation.com/institutions/aston-university-1107">Aston University</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

All the reasons a cup of coffee really can be good for you

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/justin-stebbing-1405462">Justin Stebbing</a>, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a> Consuming too much caffeine is definitely bad for your health, and there may be good reasons why some people want to <a href="https://theconversation.com/caffeine-heres-how-quitting-can-benefit-your-health-220746">quit it altogether</a>. But if you despair at the idea of giving up your morning coffee, fear not. There’s lots of research out there to show that moderate coffee intake is linked with all sorts of benefits. As well as well-known pluses improving heart health, a daily cup of coffee even seems to be good for your brain and may help prevent mental illness. For a start, coffee contains several essential nutrients beneficial to <a href="https://pubmed.ncbi.nlm.nih.gov/37764216/">overall health</a>. A typical eight-ounce cup of coffee provides small amounts of B <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8073624/">vitamins</a> – riboflavin, pantothenic acid, thiamine and niacin – as well as minerals <a href="https://pubmed.ncbi.nlm.nih.gov/25415479/">potassium, manganese, and magnesium</a>. The nutrients in coffee can contribute significantly to daily intake when multiple cups are consumed. It’s also rich in <a href="https://pubmed.ncbi.nlm.nih.gov/36361861/">antioxidants</a>. In fact, many people – especially in the west – will probably get more antioxidants from coffee than from fruit and vegetables. So what does drinking coffee actually mean for the body? One of the most <a href="https://www.ncbi.nlm.nih.gov/books/NBK209050/">well-known</a> potential benefits of coffee is its ability to <a href="https://theconversation.com/nope-coffee-wont-give-you-extra-energy-itll-just-borrow-a-bit-that-youll-pay-for-later-197897">boost energy levels</a> and improve mental <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5608989/">alertness</a>, especially first thing in the morning or during an afternoon slump. This is primarily due to caffeine, a natural stimulant found in coffee, which blocks the brain’s <a href="https://www.news-medical.net/health/What-is-Adenosine.aspx#:%7E:text=In%20the%20brain%20adenosine%20is,the%20brain%20rise%20each%20hour.">inhibitory neurotransmitter adenosine</a>, which promotes sleep and suppresses arousal. This leads to increased neuronal firing and the <a href="https://pubmed.ncbi.nlm.nih.gov/1356551/">release</a> of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4462609/">neurotransmitters</a> like <a href="https://www.ncbi.nlm.nih.gov/books/NBK223808/">dopamine</a> and <a href="https://www.ncbi.nlm.nih.gov/books/NBK537259/">norepinephrine</a>, which enhance mood, reaction time and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8202818/">cognitive function</a>. However, sometimes it’s difficult to work out cause and effect here. People drink coffee at work, for example, and in social settings with friends so research has to tease out the effects of the coffee and those of the social aspect of sharing time with friends and colleagues. <figure><iframe src="https://www.youtube.com/embed/I9xzgV7z1Bg?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <h2>Chronic diseases</h2> In the long term, moderate coffee consumption can help reduce your risk of developing a host of chronic diseases. 1. Cardiovascular diseases Moderate coffee consumption is associated with a reduced risk of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10262944/">heart disease and stroke</a>. Studies indicate that drinking one to two cups of coffee daily may lower the risk of heart failure. Additionally, <a href="https://www.acc.org/About-ACC/Press-Releases/2022/03/23/17/55/Good-News-for-Coffee-Lovers-Daily-Coffee-May-Benefit-the-Heart">coffee consumption</a> has been linked to a lower risk of cardiovascular mortality and disease. Interestingly, even when someone has abnormal heart rhythms, <a href="https://www.heart.org/en/news/2024/03/01/can-people-with-an-irregular-heartbeat-drink-coffee">coffee is not harmful</a> according to <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa2204737">recent</a> data. 2. Type 2 diabetes Coffee may enhance the body’s ability to process glucose, <a href="https://www.sciencedirect.com/science/article/abs/pii/S0939475321002374">reducing the risk</a> of developing type 2 diabetes. Research has shown that people who consume more coffee have a <a href="https://www.healthline.com/health/coffee-s-effect-diabetes">lower likelihood</a> of developing this condition. 3. Liver diseases Coffee seems to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5440772/">help protect</a> the liver appears to have protective. Both regular and decaffeinated coffee have been associated with healthier liver enzyme levels, and coffee drinkers have a <a href="https://britishlivertrust.org.uk/coffee-report/">significantly lower risk</a> of liver cirrhosis and liver cancer. 4. Cancer Coffee consumption has been linked to a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9916720/">reduced risk</a> of several other types of cancer, including colorectal and womb cancers. A systematic review found that high coffee consumption is associated with an 18% lower risk of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5696634/">cancer</a>. 5. Neurodegenerative diseases <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7773776/">Caffeine</a> is associated with a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7353179/">lower risk</a> of developing Parkinson’s disease and may help those with the condition manage their movements better. Additionally, coffee consumption may reduce the risk of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5690364/">Alzheimer’s disease</a> and other forms of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7478584/">dementia</a>. <h2>Mental health</h2> As if the physical benefits aren’t enough, coffee has also been shown to have <a href="https://www.webmd.com/mental-health/news/20230915/moderate-coffee-intake-lowers-risk-of-anxiety--depression">positive</a> effects on <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8467199/">mental health</a>. Studies suggest that coffee drinkers have a lower risk of depression, with some findings indicating a 20% reduced risk of becoming depressed. What’s more, coffee consumption has been associated with a decreased risk of suicide. Research has found that people who drink four or more cups a day are 53% less likely to commit <a href="https://pubmed.ncbi.nlm.nih.gov/23819683/">suicide</a>. <figure><iframe src="https://www.youtube.com/embed/62wEk02YKs0?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <h2>Lifespan</h2> With all these benefits, it’s not surprising that <a href="https://jamanetwork.com/journals/jamainternalmedicine/article-abstract/2686145">research suggests</a> that coffee drinkers tend to live longer than non-drinkers. A large study involving over 400,000 people found that coffee consumption over a period of 12 to 13 years was linked to a lower risk of death – with the strongest effect observed at four to five cups per day. This longevity <a href="https://www.nejm.org/doi/pdf/10.1056/NEJMoa1112010">benefit</a> could be due to the cumulative effects of coffee’s protective properties against various diseases. <h2>Moderation required</h2> While coffee offers numerous <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5696634/">health benefits</a>, it is essential to consume it in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5696634/">moderation</a>. It’s also advisable to limit added sugars and creams to avoid unnecessary calorie intake. <a href="https://www.healthline.com/nutrition/caffeine-side-effects">Excessive caffeine</a> intake can lead to negative side effects such as jitteriness, anxiety and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6292246/">sleep disturbances</a>. Some people who are especially sensitive to caffeine may need to limit their coffee intake or avoid it altogether, as even decaffeinated coffee <a href="https://www.healthline.com/nutrition/caffeine-in-decaf">contains caffeine</a>. As with any dietary component, balance is key. By understanding the potential benefits and limitations of coffee, people can make informed decisions about incorporating it into their daily routine.

Does free-to-air TV really need gambling ads to survive?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/andrew-hughes-2728">Andrew Hughes</a>, <a href="https://theconversation.com/institutions/australian-national-university-877">Australian National University</a> If anything is a sure bet right now, it’s corporate Australia’s willingness to use some variation of the “for society’s good” argument. The most recent example of this is the claim being made, including by federal minister <a href="https://www.theguardian.com/australia-news/article/2024/aug/13/gambling-ad-ban-labor-bill-shorten-tv-media-advertising-revenue">Bill Shorten</a>, that an outright ban on gambling advertising would be disastrous for free-to-air TV. To be clear, Labor still supports new restrictions on gambling advertisements, including hourly caps and bans during kids’ TV and during and around sports broadcasts. But it has rejected the idea of a total ban, prompting a <a href="https://www.smh.com.au/politics/federal/labor-mps-say-total-ban-is-the-only-way-on-gambling-ads-20240812-p5k1q0.html">backlash</a> extending as far as some of its own backbench MPs. Speaking on ABC’s Q&A on Monday night, Shorten said Australia’s free-to-air TV broadcasters were in “diabolical trouble”, with many needing gambling ad revenue “in order just to stay afloat”. “I’m not convinced that complete prohibition works,” he said. So would our commercial TV networks really fall over tomorrow without gambling ad revenue? Or is something else at play? <h2>Who is buying ads in Australia?</h2> Let’s start by building a bigger picture of where advertising spend more broadly comes from in Australia. Global analytics firm Nielsen regularly compiles <a href="https://www.nielsen.com/news-center/2024/top-20-categories-by-ad-spend-for-2023-revealed-in-latest-nielsen-ad-intel-report/#:%7E:text=Retail%20topped%20the%20list%20with,significant%20investment%20of%20%24596m.">top 20</a> lists of both the categories and individual companies spending the most on ads here. In 2023 the top category, retail, accounted for A$2.56 billion in advertising spend. Gambling and gaming, in contrast, represented just $239 million, less than a tenth of this figure. Harvey Norman topped the list of <a href="https://www.nielsen.com/news-center/2024/australias-top-20-highest-spending-advertisers-of-2023-revealed-in-latest-nielsen-ad-intel-report/">individual companies</a> in 2023. The first we see of any gambling brand is Sportsbet, which came in at 16th. For gambling companies, it’s fair to assume the lion’s share of this goes to TV. <a href="https://www.acma.gov.au/publications/2023-10/report/gambling-advertising-australia-placement-and-spending">Research</a> by the Australian Communications and Media Authority (ACMA) found 68% of gambling companies’ ad spend went to free-to-air TV markets. As for the remainder, 9% went to radio, 15% to social media and 8% to other online platforms. <h2>How much is actually getting spent?</h2> But how do we estimate the gambling industry’s total annual advertising spend? There are certainly a lot of numbers getting thrown around. One <a href="https://www.afr.com/companies/media-and-marketing/tv-networks-to-demand-fee-relief-as-40m-wagering-hole-opens-up-20240804-p5jzav">source</a> put it at $300.5 million for 2022. More recently, ACMA published detailed figures for the period between May 2022 and April 2023 which put it at just over <a href="https://www.acma.gov.au/publications/2023-10/report/gambling-advertising-australia-placement-and-spending">$238 million</a>, with $162 million of this going to free-to-air TV networks. But the way advertising is classified – what defines an advertisement – can sometimes differ between agencies. Then there is the <a href="https://www.acma.gov.au/check-if-gambling-operator-legal#register-licensed-gambling">number of brands operating</a>, which is constantly changing. In a market with so many competitors, any new entrant needs to spend big on advertising just to capture enough market share to be viable. This is why I argue that the actual figure for financial year 2023 may be slightly higher than ACMA’s widely quoted figure, accounting for the big ad spend of new entrants that may have fallen outside the time window assessed. Based on average company ad spend as a percentage of revenue and the size of the gambling industry, I estimate it could be higher, in the ballpark of $275 million. <h2>How much is that to the networks?</h2> This exercise is all about putting these figures in context. Channel Seven, for example, brought in <a href="https://www.sevenwestmedia.com.au/assets/Uploads/Final-2023-Annual-Report.pdf">$1.5 billion in revenue in 2023</a>. Even if it had received the gambling industry’s entire ad spend at my higher estimate of $275 million, this would still only account for less than 20% of its annual turnover. If that money all went to TV ads, Channel Seven’s stated 38.5% share of television advertising revenue would put its revenue from the estimated sports betting advertising at about $106 million in this example, around 7% of its total annual revenue. Losing most of that would hurt, but wouldn’t mortally threaten the business. A total ban would most likely be <a href="https://www.abc.net.au/news/2024-08-13/peta-murphy-left-online-gambling-legacy-why-isn-t-labor-adopting/104217328">phased in</a> over a number of years, not enacted overnight. Australia’s free-to-air networks would adapt, restrategise, and find and develop new markets to replace that revenue. Their management teams are far too smart to just shrug their shoulders and take a revenue hit on the corporate chin. <h2>Networks have had plenty of time to adapt</h2> Just a refresher. LinkedIn is now more than 20 years old. Facebook is 20. YouTube is 19. X (formerly known as Twitter) is 18. TikTok is seven. If free-to-air TV’s business model is so glacial it can’t function in the digital age, it probably doesn’t deserve to be operating in the big leagues. Digital is here and has been for a while now. The media industry has borne the brunt of this change, but has also had the most time to adapt to the disruptors, who are now more established oligopolies and duopolies than “cool start-ups” out of Silicon Valley. The argument that we need to protect sports gambling ads to protect the big media brands – has little to no basis. It’s a worn out argument we’ve seen time and time again – <a href="https://theconversation.com/how-the-push-to-end-tobacco-advertising-in-the-1970s-could-be-used-to-curb-gambling-ads-today-200915">big tobacco</a>, I’m looking at you. Protecting the interests of corporate Australia at the cost of society itself is a gamble none of us should be prepared to take.<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/236686/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/andrew-hughes-2728">Andrew Hughes</a>, Lecturer, Research School of Management, <a href="https://theconversation.com/institutions/australian-national-university-877">Australian National University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"Really unexpected": Lisa McCune opens up on Dancing With The Stars win

Lisa McCune has opened up about her journey on Dancing With The Stars following her "unexpected" <a href="https://oversixty.com.au/entertainment/tv/dancing-with-the-stars-champion-crowned" target="_blank" rel="noopener">win</a>. Monday night's finale of the show saw Lisa McCune and her dancing partner Ian Waite took home the mirrorball trophy against finalists Ant Middleton, James Stewart, Nikki Osborne, and Samantha Jade. After the win, McCune told <a href="https://7news.com.au/entertainment/celebrity/lisa-mccune-spills-on-unexpected-dancing-with-the-stars-win-c-15683539" target="_blank" rel="noopener">7News</a> that she was as shocked by the win as viewers were. “It really was unexpected,” McCune said. The actress added that she was extra thrilled for her dancing partner Ian Waite who has now taken out the Mirrorball Trophy for the first time. The win comes weeks after the gruelling DWTS process, which she admitted was more involved than she originally thought. “My agent said to me that somebody else had told them how difficult it was. And I thought, ‘Well, I probably needed a bit of a kick up the bum to do a bit more exercise’,” she says. “So I thought, ‘Well, it’d be good for me’. I started and I pretty quickly realised that the techniques involved and the different disciplines is pretty intense." “I think you underestimate how aerobically fit you actually need to be. But I gave it a red-hot go, and we had a really good time.” While McCune knew she did well through the competition, she said "Watching it back, I couldn’t recall any of the scores that we got because when you’re in the moment your adrenaline is kind of heightened, and (it’s like) watching it fresh.” As part of being crowned the Dancing With The Stars champion, Lisa was awarded $20,000 for her chosen charities: the RCD Foundation and the Harrison Riedel Foundation. <div> </div> “Both the charities I have a personal connection to in my local area, based on Victoria, both of them headed up by two amazing mums. These initiatives are spectacular.” Image credits: Instagram / Seven

"Really upsetting": Man turned away from concert for being in a wheelchair

A man from Melbourne has been left devastated after he was denied entry into a concert due to being a wheelchair. Dylan Taylor and his friends arrived at the Pier Bandroom in the suburb of Frankston to see one of his favourite heavy metal bands Polaris, when he ran into problems getting in the door. “I got to the front of the line, and they were checking IDs like normal, and one of the bouncers wouldn’t even acknowledge that I was there,” Taylor told <a href="https://7news.com.au/news/dylan-was-turned-away-from-seeing-his-favourite-band-because-he-uses-a-wheelchair-experts-say-its-a-common-issue-c-15618393" target="_blank" rel="noopener">7News</a>. “I was holding up my licence, and he wouldn’t look at it or take it, and they had taken everyone else’s licence." “I hadn’t really figured it out at this point ... but then the other bouncer said: ‘Nup, sorry mate, no wheelchairs’.” Taylor’s group of friends called for a manager to discuss the potential for them to “make it work”. The group was asked to wait around the side of the building for the manager, who was unable to offer any solutions. Dylan said he was told it would be a fire safety risk to let him in, and that even though in a scenario where a person injured in the venue would be carried out by bouncers during a fire, that the bouncers would not carry a wheelchair user out in the same scenario. “I’m spewin’ because, at this point, I haven’t even paid my friends back for the ticket, and I’ve ruined their night out,” he said. His friends continued to try to reason with the manager to let Dylan in, even saying they had seen a wheelchair user in the venue two weeks earlier, but to no avail. “Technically, you can have wheelchairs, but you have to be ambulant, that’s what we got out of them, in the end,” Taylor said. According to Dylan, there was no wheelchair access disclaimer on his tickets, nor on the Pier Bandroom’s website or social media, with Google Maps even displaying an accessibility widget which claimed there was a “wheelchair-accessible entrance”. A spokesperson from the Pier Bandroom parent company Endeavour Group told 7News it was sorry for the distress caused by the incident. “The Pier Hotel was originally built in the 1800s and is a historic landmark in Frankston. While the Pier Hotel has various rooms on the ground floor, the Pier Bandroom function space is only accessible by stairs, and is not wheelchair accessible,” it said. “We apologise to any ticket holders who were not given adequate information about our venue’s policies at the time of purchasing tickets to recent concerts. We regret any inconvenience or distress this may have caused. “We are taking action to update the Pier Bandroom’s website with this information and communicate with any show promoters to do the same.” Taylor said the incident at the Pier Bandroom “was the first time I’ve faced, I would say, pretty blatant discrimination”, as he has only required the wheelchair for 18 months after sustaining a permanent spine injury. “You feel pretty empty inside, and I did have a little cry in the car on the way home." “It just really upsets me thinking about people who have maybe been dealing with disability for their whole life. Who maybe haven’t had the other half of life I’ve had, to be able to go and experience these things before being in a wheelchair.” While learning to live with his disability, Taylor was pleased to learn “how many people will go out of their way to help you out” but said it was disappointing to discover just how much his autonomy was curbed by poor accessibility. “It’s been a steep learning curve,” Taylor said. “Melbourne will accept the reputation of being inclusive and accepting, but it’s not necessarily accessible.” Image credits: Google Maps / 7News / Dylan Taylor

Is Paris 2024 really achieving its goals for gender equality?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/rachael-jefferson-297850">Rachael Jefferson</a>, <a href="https://theconversation.com/institutions/charles-sturt-university-849">Charles Sturt University</a> The <a href="https://olympics.com/en/paris-2024">Paris Olympics</a> has proudly proclaimed to be the first games in 128 years to offer gender equality. This has been achieved by the <a href="https://olympics.com/ioc/news/genderequalolympics-paris-2024-making-history-on-the-field-of-play">International Olympic Committee (IOC)</a> providing an equal number of quota places for female and male athletes, while also increasing the number of women in coaching, broadcasting and sport governance roles. However, gender equality in sport is not just about the numbers – it involves dismantling systemic patriarchy piece by piece. <figure><iframe src="https://www.youtube.com/embed/uaCIpFiN6us?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>The Paris games will feature the highest proportion of women in the history of the Olympics.</figcaption></figure> <h2>Female athlete participation</h2> The ratio of female-to-male athlete parity is significant in the Paris Olympics, given <a href="https://www.theguardian.com/commentisfree/2021/jul/28/the-guardian-view-on-women-and-the-olympics-the-athletes-caught-up-now-the-ioc-must">women were banned from the first games in 1896</a> and only permitted to compete in small numbers in “female-appropriate” events four years later. There was a steady increase in female participation as the games became more popular through the 20th century. However, it was not until 1979 that the right of women to participate in sport was formally included in the first international convention (United Nations) on <a href="https://www.ohchr.org/Documents/ProfessionalInterest/cedaw.pdf">the elimination of all forms of discrimination</a> against women. It took another 33 years for women to be allowed to <a href="https://library.olympics.com/default/zoom-femme-et-sport.aspx?_lg=en-GB">compete in all events</a> on the Olympic program in 2012. At the Paris Olympics, <a href="https://www.statista.com/statistics/1090616/olympics-share-athletes-by-gender-since-1896/">50% of competing athletes are women</a>, and the Australian team has its <a href="https://www.health.gov.au/ministers/the-hon-anika-wells-mp/media/australia-supports-unesco-push-for-gender-equality-in-sport?language=en">highest ever proportion of women (55%)</a>. <h2>Women’s visibility</h2> The IOC has been working hard at shaking off its patriarchal reputation for the past three decades or so. Two major milestones were the establishment of the <a href="https://olympics.com/ioc/gender-equality/gender-equality-through-time">Women and Sport Working Group</a> in 1995, and the <a href="https://www.europarl.europa.eu/RegData/etudes/BRIE/2019/635560/EPRS_BRI(2019)635560_EN.pdf">amending of the Olympic Charter</a> a year later to include advancing women in sport as an Olympic principle. Despite this progress, women’s Olympic events have often been <a href="https://revista-apunts.com/en/media-representation-of-women-athletes-at-the-olympic-games-a-systematic-review/">sidelined by the media</a>, enabling male athletes to enjoy greater publicity (and associated sponsorship) than their female counterparts. The long-established scheduling of events <a href="https://www.jou.ufl.edu/insights/gender-based-sports-coverage-a-quarter-century-of-prime-time-summer-olympics/">offers male athletes peak viewing times</a> across the globe, thereby consigning many women to the margins. In Paris, this <a href="https://olympics.com/ioc/news/genderequalolympics-paris-2024-making-history-on-the-field-of-play">gender discrimination</a> has been disrupted to better the balance. Combat and strength sports are now based on weight categories, permitting the women’s and men’s events to alternate instead of having men’s events available in the popular evening slot. The women’s marathon – only introduced to the Olympics in 1984 – will <a href="https://worldathletics.org/news/news/key-information-athletics-paris-2024-olympic-games">also conclude the athletics program</a> instead of the men’s for the first time. <h2>Media representation</h2> Amplifying women’s voices and stories from the games has been a key objective for the Paris Olympics. The IOC has been instrumental in this endeavour via its <a href="https://olympics.com/ioc/gender-equality/portrayal-guidelines">2024 Portrayal Guidelines:</a> gender-equal, fair and inclusive representation in sport. These guidelines have led to a large increase in the number of female staff in broadcast roles and production teams in Paris. And <a href="https://olympics.com/ioc/news/olympic-broadcasting-more-women-in-key-broadcast-roles-at-paris-2024">female-targeted training camps</a> in 2023 provided by the Olympic Broadcasting Services (OBS) have been a timely institutional transformation. Improved media representation of female athletes is also a priority, focusing on how they are visually captured and presented in all forms of media and communication. This helps to reframe persistent patriarchal narratives about how sportswomen must <a href="https://theconversation.com/uniform-discontent-how-women-athletes-are-taking-control-of-their-sporting-outfits-164946">maintain their femininity</a> to be worthy recipients of the <a href="https://vc.bridgew.edu/cgi/viewcontent.cgi?article=1269&context=grad_rev">male gaze</a>. Regrettably, this is still a work in progress for some commentators such as <a href="https://www.skynews.com.au/business/media/you-know-what-women-are-like-eurosport-commentator-bob-ballard-sacked-for-sexist-remark-after-australias-freestyle-relay-win/news-story/739bc7a0efaf9d7007250ab0c4313f15">Bob Bollard, whose recent sexist “makeup” remark</a> went viral when he was reporting on the gold medal win for the Australian women’s 4x100m freestyle relay team. After the Bollard incident, Yiannis Exarchos, the <a href="https://www.scmp.com/yp/discover/news/sports/article/3272286/paris-olympics-camera-operators-told-avoid-filming-women-sexist-way">OBS chief, swiftly reminded</a> mostly male camera operators to refrain from any sexist filming of female athletes. He said the problem was mainly down to “unconscious bias”, with camera operators and TV editors tending to show more close-up shots of women than men. <h2>Leadership and infrastructure</h2> Female under-representation in the IOC is well documented. There were <a href="https://www.europarl.europa.eu/RegData/etudes/BRIE/2019/635560/EPRS_BRI(2019)635560_EN.pdf">no women in the IOC from 1896 to 1981</a> before Flor Isava Fonseca (Venezuela) and Pirjo Häggman (Finland) were co-opted as the <a href="https://stillmed.olympics.com/media/Documents/Olympic-Movement/Factsheets/Women-in-the-Olympic-Movement.pdf">first two female IOC members in 1981</a>. In the IOC’s most recent election in July, the number of <a href="https://olympics.com/ioc/news/ioc-session-in-paris-elects-two-new-vice-presidents-and-eight-ioc-members">female members rose to 42.3%</a> – more than a 100% increase in the past decade. Following a long overdue <a href="https://unwomen.org.au/paris-2024-olympics-a-new-era-for-women-in-sport/">IOC rule change in 2020</a>, the traditional male flag bearer in the Olympics Opening Ceremony was accompanied by a female. Gender issues arise with elite sport coaches too – <a href="https://olympics.com/ioc/female-coaches">only 13% of coaches</a> at the 2020 Tokyo Olympics were women. In Paris, it is estimated <a href="https://www.telegraph.co.uk/olympics/2024/07/27/female-coaches-misogyny-olympics-paris-2024-equality-wish/#:%7E:text=At%20the%20Tokyo%20Olympics%20in,10%20coaches%20will%20be%20female.">one in ten coaches are female</a>. Outrage about <a href="https://abcnews.go.com/GMA/Culture/nikes-olympic-track-womens-uniforms-criticized-athletes-sexism/story?id=109267006">sexist Nike uniforms</a> and the <a href="https://theconversation.com/the-olympics-and-fifa-are-trying-to-better-support-mum-aletes-what-are-australian-sports-doing-233218">lack of facilities for “mum-aletes”</a> until the 2024 games both highlight the incessant institutional hurdles elite sportswomen encounter. <h2>A new era for female athletes</h2> The Paris games are a springboard for much needed systemic change in the minutiae of Olympic policies and practices. Female athletes are no longer victims of vast patriarchal conspiracies to lock them out of this male-dominated arena. They’ve gained ground and are kicking sexism to the touchline with relish. We all need to welcome in this new era.<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/235665/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/rachael-jefferson-297850">Rachael Jefferson</a>, Lecturer in Human Movement Studies (Health and PE) and Creative Arts, <a href="https://theconversation.com/institutions/charles-sturt-university-849">Charles Sturt University</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

A few ancient writers, such as the historian <a href="https://quod.lib.umich.edu/m/moa/acl3129.0001.001/320">Aristodemus of Elis</a> (who lived in the 2nd century AD or earlier), <a href="https://www.attalus.org/translate/eusebius2.html#:%7E:text=Aristodemus%20of%20Elis,in%20between%20them.">believed</a> there had been as many as 27 Olympic contests prior to 776 BC, but the results had never been recorded because people before that time did not care about recording the names of the winners. The games were held every four years at <a href="https://www.britannica.com/place/Olympia-ancient-site-Greece">Olympia</a>, a site in Western Greece that had a famous temple to the god <a href="https://www.britannica.com/topic/Zeus">Zeus</a>. The games started in mid-August and were part of a religious festival dedicated to Zeus. <figure><iframe src="https://www.youtube.com/embed/VdHHus8IgYA?wmode=transparent&start=25" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>The Olympics began as part of a religious festival honouring the Greek god Zeus.</figcaption></figure> <h2>Competing for glory</h2> In the early days of the Olympics, there was only one event (the “<a href="https://www.britannica.com/sports/stade-footrace#:%7E:text=ancient%20Olympic%20Games&text=The%20race%2C%20known%20as%20the,the%20diaulos%2C%20roughly%20similar%20to%E2%80%A6">stadion</a>”) and one victor. Over the centuries, other events were added, like chariot races, wrestling, long-distance running and boxing. The Roman emperor <a href="https://www.britannica.com/biography/Nero-Roman-emperor">Nero</a> (37-68 AD) even “introduced a musical competition at Olympia”, as the biographer <a href="https://www.oxfordreference.com/display/10.1093/acref/9780198606413.001.0001/acref-9780198606413-e-6117">Suetonius</a> (1st/2nd century AD) <a href="https://www.loebclassics.com/view/LCL038/1914/volume.xml">informs</a> us. Victors at Olympia won a wreath of wild olive. Unlike today, there were no prizes for second or third. The athlete <a href="http://www.perseus.tufts.edu/hopper/text?doc=Perseus%3Atext%3A1999.04.0104%3Aalphabetic+letter%3DI%3Aentry+group%3D2%3Aentry%3Diccus-bio-1">Iccus of Tarentum</a>, who lived in the 5th century BC and won victory in the pentathlon at the Olympics of 476 BC, apparently <a href="https://www.loebclassics.com/view/LCL448/1959/volume.xml">said</a> that for him “the prizes meant glory, admiration in his lifetime, and after death an honoured name”. Mostly men competed for the prizes but some women took part. <a href="https://www.jstor.org/stable/43610326">Cynisca</a>, daughter of King <a href="https://www.britannica.com/biography/Archidamus-II">Archidamus II of Sparta</a>, was the first woman to achieve an Olympic victory. She got the prize because the horses she trained won the chariot racing event in the year 396 BC, as the traveller <a href="https://www.britannica.com/biography/Pausanias-Greek-geographer">Pausanias</a> (2nd century AD) <a href="https://www.loebclassics.com/view/LCL188/1926/volume.xml">writes</a>: <blockquote> Cynisca was exceedingly ambitious to succeed at the Olympic games and was the first woman to breed horses and the first to win an Olympic victory. After Cynisca, other women have won Olympic victories but none of them was more distinguished for their victories than her. </blockquote> But competing in the games could be dangerous. <a href="https://www.oxfordreference.com/display/10.1093/oi/authority.20110803100454522">Lucius Annaeus Seneca</a> (c. 50 BC-c. 40 AD) <a href="https://www.loebclassics.com/view/LCL463/1974/volume.xml">describes</a> how a father lost both sons in the “<a href="https://www.britannica.com/sports/pankration">pancration</a>”, a type of combat sport that was a violent mixture of boxing and wrestling: <blockquote> A man trained his two sons as pancratists, and presented them to compete at the Olympic games. They were paired off to fight each other. The youths were both killed together and had divine honours decreed to them. </blockquote> <h2>Going to the games</h2> People travelled far to see the athletes competing in the famous games. The rhetorician <a href="https://www.oxfordreference.com/display/10.1093/acref/9780198606413.001.0001/acref-9780198606413-e-4094">Menander</a> (3rd/4th century AD) <a href="https://www.loebclassics.com/view/LCL539/2019/volume.xml">said</a> of the Olympic games: “the journey there is very difficult but nevertheless people take the risk”. In 44 BC, the Roman statesman <a href="https://www.britannica.com/biography/Cicero">Cicero</a> (106-43 BC) <a href="https://books.google.com.au/books?id=BzJsGtpNTwMC&pg=PA125&dq=%22A+winter+voyage+is+disagreeable,+and+that+is+why+I+asked+you%22&hl=en&newbks=1&newbks_redir=0&sa=X&ved=2ahUKEwjd5ca9m62HAxXKSWwGHf13DPEQ6AF6BAgKEAI#v=onepage&q=%22A%20winter%20voyage%20is%20disagreeable%2C%20and%20that%20is%20why%20I%20asked%20you%22&f=false">wrote</a> a letter to his friend Atticus about planning a trip to Greece to see the games: <blockquote> I should like to know the date of the Olympic games […] of course, as you say, the plan of my trip will depend on chance. </blockquote> Cicero never made it to the Olympics – he was interrupted by other business. If he had gone, the trip would have involved a voyage by sea from Italy to Greece, then a carriage ride to Olympia. Once at Olympia, travellers stayed at lodging houses with other travellers. There they mixed with strangers and made new friends. There is a famous story about what happened when the philosopher <a href="https://www.britannica.com/biography/Plato">Plato</a> (428/427-348/347 BC) stayed at Olympia for the games. Plato lived there with others who did not realise he was the celebrated philosopher and he made a good impression on them, as the Roman writer <a href="https://www.britannica.com/biography/Aelian#:%7E:text=Aelian%20(born%20c.,%22Honey%2Dtongued%22).">Claudius Aelian</a> (2nd/3rd century AD) <a href="https://www.loebclassics.com/view/LCL486/1997/volume.xml">recalled</a>: <blockquote> The strangers were delighted by their chance encounter […] he had behaved towards them with modesty and simplicity and had proved himself able to win the confidence of anyone in his company. </blockquote> Later on, Plato invited his new friends to Athens and they were amazed to find out he was in fact the famous philosopher who was the student of <a href="https://www.britannica.com/biography/Socrates">Socrates</a>. It’s unclear how many people actually visited the ancient games each time they were held, although some modern scholars <a href="https://olympics.com/ioc/ancient-olympic-games/spectators">think</a> the number could have been as high as 50,000 in some years. <h2>Watching the games</h2> The Greek writer <a href="https://www.britannica.com/biography/Chariton-Greek-author">Chariton</a> (1st century AD) in his novel Callirhoe <a href="https://www.loebclassics.com/view/LCL481/1995/volume.xml">wrote</a> how athletes – who had often also made a long journey to get to the games – arrived at Olympia “with an escort of their supporters”. Athletes competed naked, and women were usually not permitted to watch. But there were some exceptions. For example a woman called Pherenice, who lived in the 4th century BC, was permitted to attend the Olympics as a spectator. As Claudius Aelian <a href="https://www.loebclassics.com/view/LCL486/1997/volume.xml">explains</a>: <blockquote> Pherenice brought her son to the Olympic festival to compete. The presiding officials refused to admit her as a spectator but she spoke in public and justified her request by pointing out that her father and three brothers were Olympic victors, and she was bringing a son who was a competitor. She won over the assembly and she attended the Olympic festival. </blockquote> As the contest was held in the middle of summer, it was usually extremely hot. According to Claudius Aelian, some people <a href="https://www.loebclassics.com/view/LCL486/1997/volume.xml">thought</a> watching the Olympics under “the baking heat of the sun” was a “much more severe penalty” than having to do manual labour such as grinding grain. The site at Olympia also had problems with freshwater supply. According to the writer <a href="https://www.britannica.com/biography/Lucian">Lucian of Samosata</a> (2nd century AD), visitors to the games sometimes <a href="https://www.tertullian.org/rpearse/lucian/peregrinus.htm#:%7E:text=Coming%20at%20last,that%20same%20water!">died of thirst</a>. This problem was fixed when <a href="https://www.britannica.com/biography/Herodes-Atticus">Herodes Atticus</a> built an <a href="http://www.perseus.tufts.edu/hopper/artifact?name=Olympia%2C+Nymphaeum&object=Building">aqueduct</a> to the site in the middle of the 2nd century AD. The atmosphere of the crowd was electric. The Athenian general and politician <a href="https://penelope.uchicago.edu/Thayer/E/Roman/Texts/Plutarch/Lives/Themistocles*.html">Themistocles</a> (6th/5th century BC) apparently <a href="https://www.loebclassics.com/view/LCL486/1997/volume.xml">said</a> the most enjoyable moment of his life was “to see the public at Olympia turning to look at me as I entered the stadium”. They praised him when he visited the games at Olympia because of his recent victory against the Persians at the <a href="https://www.britannica.com/event/Battle-of-Salamis">battle of Salamis</a> (480 BC). When the games were over, winning athletes returned home to a hero’s welcome. According to Claudius Aelian, when the athlete <a href="https://ia801308.us.archive.org/18/items/PWRE09-10/Pauly-Wissowa_V1_1151.png">Dioxippus</a> (4th century BC) <a href="https://www.loebclassics.com/view/LCL486/1997/volume.xml">returned to Athens</a> after being victorious in the pancration at Olympia, “a crowd collected from all directions” in the city to celebrate him. <h2>The end of the ancient games</h2> The Roman historian <a href="https://www.oxfordreference.com/display/10.1093/oi/authority.20110803115406219">Velleius Paterculus</a> (born 20/19 BC) <a href="https://www.loebclassics.com/view/LCL152/1924/volume.xml">called</a> the Olympic games “the most celebrated of all contests in sports”. Current research <a href="https://www.cambridge.org/core/books/end-of-greek-athletics-in-late-antiquity/DF60B2B859B4F1A7FE7549B17B61E9A1">suggests</a> the ancient games probably ended in the reign of the Roman emperor Theodosius II (reigned 408-450 AD). There may have been a number of reasons for the demise but some ancient sources specifically <a href="http://ancientolympics.arts.kuleuven.be/sourceEN/D219EN.html#:%7E:text=Scholia%20in%20Lucianum%2041.9.42%2D46%3A%0AThe%20Olympic%20games%20%C3%AF%C2%BF%C2%BD%20existed%20for%20a%20long%20time%20until%20Theodosius%20the%20younger%2C%20who%20was%20the%20son%20of%20Arcadius.%20After%20the%20temple%20of%20Olympian%20Zeus%20had%20been%20burnt%20down%2C%20the%20festival%20of%20the%20Eleans%20and%20Olympic%20contest%20were%20abandoned.">say</a> it was caused by a fire that destroyed the temple of Zeus at Olympia during Theodosius II’s reign: <blockquote> After the temple of Olympian Zeus had been burnt down, the festival of the Eleans and the Olympic contest were abandoned. </blockquote> The Olympics were not revived again until 1896, the year of the first <a href="https://olympics.com/en/olympic-games/athens-1896">modern Olympics</a>.<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/234912/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/konstantine-panegyres-1528527">Konstantine Panegyres</a>, McKenzie Postdoctoral Fellow, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> Image: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Cranberry juice really can help with UTIs – and reduce reliance on antibiotics

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/christian-moro-121754">Christian Moro</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> and <a href="https://theconversation.com/profiles/charlotte-phelps-1187658">Charlotte Phelps</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> Cranberry juice has been <a href="https://www.ncbi.nlm.nih.gov/books/NBK92762/">used medicinally for centuries</a>. Our new research indicates it should be a normal aspect of urinary tract infection (UTI) management today. While some benefits of cranberry compounds for the prevention of UTIs have been suspected for <a href="https://theconversation.com/cranberry-juice-can-prevent-recurrent-utis-but-only-for-some-people-203926">some time</a>, it hasn’t been clear whether the benefits from cranberry juice were simply from drinking <a href="https://bjgp.org/content/70/692/e200">more fluid</a>, or something in the fruit itself. For our <a href="https://www.sciencedirect.com/science/article/pii/S2405456924001226">study</a>, published this week, we combined and collectively assessed 3,091 participants across more than 20 clinical trials. Our analysis indicates that increasing liquids reduces the rate of UTIs compared with no treatment, but cranberry in liquid form is even better at reducing UTIs and antibiotic use. <h2>Are UTIs really that bad?</h2> Urinary tract infections affect more than <a href="https://journals.sagepub.com/doi/pdf/10.1177/1756287219832172">50% of women</a> and <a href="https://bjgpopen.org/content/bjgpoa/5/2/bjgpopen20X101140.full.pdf">20% of men</a> in their lifetime. Most commonly, UTIs are caused from the bug called Escherichia coli (E.coli). This bug lives harmlessly in our <a href="https://www.ncbi.nlm.nih.gov/books/NBK562895/">intestines</a>, but can cause infection in the <a href="http://doi.org/10.33235/anzcj.30.1.4-10">urinary tract</a>. This is why, particularly for women, it is recommended people wipe from front to back after using the toilet. An untreated UTI can move up to the kidneys and cause even more serious illness. Even when not managing infection, many people are anxious about contracting a UTI. Sexually active women, pregnant women and older women may all be at <a href="https://www.ncbi.nlm.nih.gov/books/NBK436013/">increased risk</a>. <h2>Why cranberries?</h2> To cause a UTI, the bacteria need to attach to the wall of the <a href="https://www.nature.com/articles/s41598-023-44916-8">urinary bladder</a>. Increasing fluids helps to flush out bacteria before it attaches (or makes its way up into the bladder). Some beneficial compounds in cranberry, such as <a href="https://www.cochrane.org/CD001321/RENAL_cranberries-preventing-urinary-tract-infections">proanthocyanidins</a> (also called condensed tannins), prevent the bacteria from attaching to the wall itself. While there are treatments, over 90% of the bugs that cause UTIs exhibit some form of <a href="https://www.who.int/news-room/fact-sheets/detail/antimicrobial-resistance">microbial resistance</a>. This suggests that they are rapidly changing and some cases of UTI might be left <a href="https://www.scientificamerican.com/article/antibiotic-resistant-utis-are-common-and-other-infections-may-soon-be-resistant-too/">untreatable</a>. <h2>What we found</h2> Our analysis <a href="https://www.sciencedirect.com/science/article/pii/S2405456924001226">showed</a> a 54% lower rate of UTIs from cranberry juice consumption compared to no treatment. This means that significantly fewer participants who regularly consumed cranberry juice (most commonly around 200 millilitres each day) reported having a UTI during the periods assessed in the studies we analysed. Cranberry juice was also linked to a 49% lower rate of antibiotic use than placebo liquid and a 59% lower rate than no treatment, based on analysis of indirect and direct effects across six studies. The use of cranberry compounds, whether in drinks or tablet form, also reduced the prevalence of symptoms associated with UTIs. While some studies we included presented conflicts of interest (such as receiving funding from cranberry companies), we took this “high risk of bias” into account when analysing the data. <h2>So, when can cranberry juice help?</h2> We found three main benefits of cranberry juice for UTIs. 1. Reduced rates of infections Increasing fluids (for example, drinking more water) reduced the prevalence of UTIs, and taking cranberry compounds (such as tablets) was also beneficial. But the most benefits were identified from increasing fluids and taking cranberry compounds at the same time, such as with cranberry juice. 2. Reduced use of antibiotics The data shows cranberry juice lowers the need to use antibiotics by 59%. This was identified as fewer participants in randomised cranberry juice groups required antibiotics. Increasing fluid intake also helped reduce antibiotic use (by 25%). But this was not as useful as increasing fluids at the same time as using cranberry compounds. Cranberry compounds alone (such as tablets without associated increases in fluid intake) did not affect antibiotic use. 3. Reducing symptoms Taking cranberry compounds (in any form, liquid or tablet) reduced the symptoms of UTIs, as measured in the overall data, by more than five times. <h2>Take home advice</h2> While cranberry juice cannot treat a UTI, it can certainly be part of UTI management. If you suspect that you have a UTI, see your GP as soon as possible.<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/235314/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/christian-moro-121754">Christian Moro</a>, Associate Professor of Science & Medicine, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> and <a href="https://theconversation.com/profiles/charlotte-phelps-1187658">Charlotte Phelps</a>, Senior Teaching Fellow, Medical Program, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.
