Do any non-drug treatments help back pain? Here’s what the evidence says

<div class="theconversation-article-body"> <p>Jason, a 42-year-old father of two, has been battling back pain for weeks. Scrolling through his phone, he sees ad after ad promising relief: chiropractic alignments, acupuncture, back braces, vibrating massage guns and herbal patches.</p> <p>His GP told him to “stay active”, but what does that even mean when every movement hurts? Jason wants to avoid strong painkillers and surgery, but with so many options (and opinions), it’s hard to know what works and what’s just marketing hype.</p> <p>If Jason’s experience sounds familiar, you’re not alone. Back pain is one of the most common reasons people visit a doctor. It can be challenging to manage, mainly due to widespread <a href="https://theconversation.com/having-good-posture-doesnt-prevent-back-pain-and-bad-posture-doesnt-cause-it-183732">misunderstandings</a> and the <a href="https://ebm.bmj.com/content/early/2025/03/02/bmjebm-2024-112974">overwhelming number</a> of ineffective and uncertain treatments promoted.</p> <p>We assessed the best available evidence of non-drug and non-surgical treatments to alleviate low back pain. <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD014691.pub2/full">Our review</a> – published today by the independent, international group the Cochrane Collaboration – includes 31 Cochrane systematic reviews, covering 97,000 people with back pain.</p> <p>It <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD014691.pub2/full">shows</a> bed rest doesn’t work for back pain. Some of the treatments that do work can depend on how long you’ve been in pain.</p> <h2>Is back pain likely to be serious?</h2> <p>There are different types of low back pain. It can:</p> <ul> <li>be short-lived, lasting less than six weeks (acute back pain)</li> <li>linger for a bit longer, for six to twelve weeks (sub-acute)</li> <li>stick around for months and even years (chronic, defined as more than 12 weeks).</li> </ul> <p>In <a href="https://www.thelancet.com/article/S0140-6736(16)30970-9/abstract">most cases</a> (90-95%), back pain is non-specific and cannot be reliably linked to a specific cause or underlying disease. This includes common structural changes seen in x-rays and MRIs of the spine.</p> <p>For this reason, imaging of the back is <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(09)60172-0/abstract">only</a> recommended in rare situations – typically when there’s a clear suspicion of serious back issues, such as after physical trauma or when there is numbness or loss of sensation in the groin or legs.</p> <p>Many people expect to receive <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD013815.pub2/full">painkillers</a> for their back pain or even surgery, but these are no longer the front-line treatment options due to limited benefits and the high risk of harm.</p> <p>International <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(18)30489-6/fulltext">clinical guidelines</a> recommend people choose non-drug and non-surgical treatments to relieve their pain, improve function and reduce the distress commonly associated with back pain.</p> <p>So what works for different types of pain? Here’s what <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD014691.pub2/full">our review found</a> when researchers compared these treatments with standard care (the typical treatment patients usually receive) or no treatment.</p> <h2>What helps for short-term back pain</h2> <p><strong>1. Stay active – don’t rest in bed</strong></p> <p>If your back pain is new, the best advice is also one of the simplest: keep moving despite the pain.</p> <p>Changing the way you move and use your body to protect it, or resting in bed, can seem like to right way to respond to pain – and may have even been recommended in the past. But we know know this excessive protective behaviour can make it harder to return to meaningful activities.</p> <p>This doesn’t mean pushing through pain or hitting the gym, but instead, trying to maintain your usual routines as much as possible. Evidence suggests that doing so won’t make your pain worse, and may improve it.</p> <p><strong>2. Multidisciplinary care, if pain lingers</strong></p> <p>For pain lasting six to 12 weeks, multidisciplinary treatment is likely to reduce pain compared to standard care.</p> <p>This involves a coordinated team of doctors, physiotherapists and psychologists working together to address the many factors contributing to your back pain persisting:</p> <ul> <li> <p>neurophysiological influences refer to how your nervous system is currently processing pain. It can make you more sensitive to signals from movements, thoughts, feelings and environment</p> </li> <li> <p>psychological factors include how your thoughts, feelings and behaviours affect your pain system and, ultimately, the experience of pain you have</p> </li> <li> <p>occupational factors include the physical demands of your job and how well you can manage them, as well as aspects like low job satisfaction, all of which can contribute to ongoing pain.</p> </li> </ul> <h2>What works for chronic back pain</h2> <p>Once pain has been around for more than 12 weeks, it can become more difficult to treat. But relief is still possible.</p> <p><strong>Exercise therapy</strong></p> <p>Exercise – especially programs tailored to your needs and preferences – is likely to reduce pain and help you move better. This could include aerobic activity, strength training or Pilates-based movements.</p> <p>It doesn’t seem to matter what type of exercise you do – it matters more that you are consistent and have the right level of supervision, especially early on.</p> <p><strong>Multidisciplinary treatment</strong></p> <p>As with short-term pain, coordinated care involving a mix of physical, occupational and psychological approaches likely works better than usual care alone.</p> <p><strong>Psychological therapies</strong></p> <p>Psychological therapies for chronic pain include approaches to help people change thinking, feelings, behaviours and reactions that might sustain persistent pain.</p> <p>These approaches are likely to reduce pain, though they may not be as effective in improving physical function.</p> <p><strong>Acupuncture</strong></p> <p>Acupuncture probably reduces pain and improves how well you can function compared to placebo or no treatment.</p> <p>While some debate remains about how it works, the evidence suggests potential benefits for some people with chronic back pain.</p> <h2>What doesn’t work or still raises uncertainty?</h2> <p>The review found that many commonly advertised treatments still have uncertain benefits or probably do not benefit people with back pain.</p> <p>Spinal manipulation, for example, has uncertain benefits in acute and chronic back pain, and it likely does not improve how well you function if you have acute back pain.</p> <p>Traction, which involves stretching the spine using weights or pulleys, probably doesn’t help with chronic back pain. Despite its popularity in some circles, there’s little evidence that it works.</p> <p>There isn’t enough reliable data to determine whether advertised treatments – such back braces, vibrating massage guns and herbal patches – are effective.</p> <h2>How can you use the findings?</h2> <p>If you have back pain, start by considering how long you’ve had it. Then explore treatment options that research supports and discuss them with your GP, psychologist or physiotherapist.</p> <p>Your health provider should reassure you about the importance of gradually increasing your activity to resume meaningful work, social and life activities. They should also support you in making informed decisions about which treatments are most appropriate for you at this stage.</p> <p><em><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/253122/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" />By <a href="https://theconversation.com/profiles/rodrigo-rossi-nogueira-rizzo-1544189">Rodrigo Rossi Nogueira Rizzo</a>, Postdoctoral Research Fellow, <a href="https://theconversation.com/institutions/neuroscience-research-australia-976">Neuroscience Research Australia</a> and <a href="https://theconversation.com/profiles/aidan-cashin-2355450">Aidan Cashin</a>, NHMRC Emerging Leadership Fellow, <a href="https://theconversation.com/institutions/neuroscience-research-australia-976">Neuroscience Research Australia</a></em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How we diagnose and define obesity is set to change – here’s why, and what it means for treatment

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/louise-baur-5284">Louise Baur</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/john-b-dixon-11630">John B. Dixon</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a>; <a href="https://theconversation.com/profiles/priya-sumithran-1529047">Priya Sumithran</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a>, and <a href="https://theconversation.com/profiles/wendy-a-brown-1665">Wendy A. Brown</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a></em></p> <p>Obesity is <a href="https://www.niddk.nih.gov/health-information/weight-management/adult-overweight-obesity/health-risks#:%7E:text=Having%20overweight%20or%20obesity%20increases,the%20cells%20in%20your%20body">linked to</a> many common diseases, such as type 2 diabetes, heart disease, fatty liver disease and knee osteoarthritis.</p> <p>Obesity is currently defined using a person’s body mass index, or BMI. This is <a href="https://www.who.int/news-room/fact-sheets/detail/obesity-and-overweight">calculated</a> as weight (in kilograms) divided by the square of height (in metres). In people of European descent, the BMI for obesity is 30 kg/m² and over.</p> <p>But the risk to health and wellbeing is not determined by weight – and therefore BMI – alone. We’ve been part of a global collaboration that has spent the past two years discussing how this should change. Today we publish how we think obesity should be defined and why.</p> <p>As we outline in <a href="https://www.thelancet.com/commissions/clinical-obesity">The Lancet</a>, having a larger body shouldn’t mean you’re diagnosed with “clinical obesity”. Such a diagnosis should depend on the level and location of body fat – and whether there are associated health problems.</p> <h2>What’s wrong with BMI?</h2> <p>The risk of ill health depends on the relative percentage of fat, bone and muscle making up a person’s body weight, as well as where the fat is distributed.</p> <p>Athletes with a relatively high muscle mass, for example, may have a higher BMI. Even when that athlete has a BMI over 30 kg/m², their higher weight is due to excess muscle rather than excess fatty tissue.</p> <p>People who carry their excess fatty tissue <a href="https://www.abc.net.au/news/health/2017-09-06/waist-size-why-it-matters-and-when-its-a-risk/8839708">around their waist</a> are at greatest risk of the health problems associated with obesity.</p> <p>Fat stored deep in the abdomen and around the internal organs can release damaging molecules into the blood. These can then <a href="https://theconversation.com/body-fat-deep-below-the-surface-is-a-toxic-risk-especially-for-your-heart-146307">cause problems</a> in other parts of the body.</p> <p>But BMI alone does not tell us whether a person has health problems related to excess body fat. People with excess body fat don’t always have a BMI over 30, meaning they are not investigated for health problems associated with excess body fat. This might occur in a very tall person or in someone who tends to store body fat in the abdomen but who is of a “healthy” weight.</p> <p>On the other hand, others who aren’t athletes but have excess fat may have a high BMI but no associated health problems.</p> <p>BMI is therefore an imperfect tool to help us diagnose obesity.</p> <h2>What is the new definition?</h2> <p>The goal of the <a href="https://pubmed.ncbi.nlm.nih.gov/36878238">Lancet Diabetes & Endocrinology Commission on the Definition and Diagnosis of Clinical Obesity </a> was to develop an approach to this definition and diagnosis. The commission, established in 2022 and led from King’s College London, has brought together 56 experts on aspects of obesity, including people with lived experience.</p> <p>The commission’s <a href="https://www.thelancet.com/commissions/clinical-obesity">definition and new diagnostic criteria</a> shifts the focus from BMI alone. It incorporates other measurements, such as waist circumference, to confirm an excess or unhealthy distribution of body fat.</p> <p>We define two categories of obesity based on objective signs and symptoms of poor health due to excess body fat.</p> <p><strong>1. Clinical obesity</strong></p> <p>A person with clinical obesity has signs and symptoms of ongoing organ dysfunction and/or difficulty with day-to-day activities of daily living (such as bathing, going to the toilet or dressing).</p> <p>There are 18 diagnostic criteria for clinical obesity in adults and 13 in children and adolescents. These include:</p> <ul> <li> <p>breathlessness caused by the effect of obesity on the lungs</p> </li> <li> <p>obesity-induced heart failure</p> </li> <li> <p>raised blood pressure</p> </li> <li> <p>fatty liver disease</p> </li> <li> <p>abnormalities in bones and joints that limit movement in children.</p> </li> </ul> <p><strong>2. Pre-clinical obesity</strong></p> <p>A person with pre-clinical obesity has high levels of body fat that are not causing any illness.</p> <p>People with pre-clinical obesity do not have any evidence of reduced tissue or organ function due to obesity and can complete day-to-day activities unhindered.</p> <p>However, people with pre-clinical obesity are generally at higher risk of developing diseases such as heart disease, some cancers and type 2 diabetes.</p> <h2>What does this mean for obesity treatment?</h2> <p>Clinical obesity is a disease requiring access to effective health care.</p> <p>For those with clinical obesity, the focus of health care should be on improving the health problems caused by obesity. People should be offered evidence-based treatment options after discussion with their health-care practitioner.</p> <p><a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(24)01210-8/abstract">Treatment</a> will <a href="https://www.thelancet.com/journals/landia/article/PIIS2213-8587(22)00047-X/fulltext">include</a> management of obesity-associated complications and may include specific obesity treatment aiming at decreasing fat mass, such as:</p> <ul> <li> <p>support for <a href="https://www.obesityevidencehub.org.au/collections/treatment/behavioural-interventions-for-the-management-of-overweight-and-obesity-in-adults">behaviour change</a> <a href="https://www.obesityevidencehub.org.au/collections/treatment/managing-overweight-and-obesity-in-children-and-adolescents">around</a> diet, physical activity, sleep and screen use</p> </li> <li> <p>obesity-management medications to reduce appetite, lower weight and <a href="https://www.obesityevidencehub.org.au/collections/treatment/medication-and-surgery-for-the-treatment-of-overweight-and-obesity-in-adults">improve health</a> outcomes such as blood glucose (sugar) and blood pressure</p> </li> <li> <p>metabolic <a href="https://theconversation.com/thinking-about-bariatric-surgery-for-weight-loss-heres-what-to-consider-184153">bariatric surgery</a> to treat obesity or reduce weight-related health complications.</p> </li> </ul> <h2>Should pre-clinical obesity be treated?</h2> <p>For those with pre-clinical obesity, health care should be about risk-reduction and prevention of health problems related to obesity.</p> <p>This may require health counselling, including support for health behaviour change, and monitoring over time.</p> <p>Depending on the person’s individual risk – such as a family history of disease, level of body fat and changes over time – they may opt for one of the obesity treatments above.</p> <p>Distinguishing people who don’t have illness from those who already have ongoing illness will enable personalised approaches to obesity prevention, management and treatment with more appropriate and cost-effective allocation of resources.</p> <h2>What happens next?</h2> <p>These new criteria for the diagnosis of clinical obesity will need to be adopted into national and international clinical practice guidelines and a range of obesity strategies.</p> <p>Once adopted, training health professionals and health service managers, and educating the general public, will be vital.</p> <p>Reframing the narrative of obesity may help eradicate misconceptions that contribute to stigma, including making false assumptions about the health status of people in larger bodies. A better understanding of the biology and health effects of obesity should also mean people in larger bodies are not blamed for their condition.</p> <p>People with obesity or who have larger bodies should expect personalised, evidence-based assessments and advice, free of stigma and blame.<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/245164/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/louise-baur-5284"><em>Louise Baur</em></a><em>, Professor, Discipline of Child and Adolescent Health, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/john-b-dixon-11630">John B.

Why do some people’s hair and nails grow quicker than mine?

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/michelle-moscova-310728">Michelle Moscova</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em></p> <p>Throughout recorded history, our hair and nails played an important role in signifying who <a href="https://www.psychiatrictimes.com/view/gender-culture-and-social-constructs-in-body-focused-repetitive-behaviors">we are and our social status</a>. You could say, they separate the caveman from businessman.</p> <p>It was no surprise then that many of us found a new level of appreciation for our hairdressers and nail artists during the COVID lockdowns. Even Taylor Swift reported <a href="https://abcnews.go.com/GMA/Culture/taylor-swift-reveals-shes-cutting-hair-covid-19/story?id=74757540&t">she cut her own hair during lockdown</a>.</p> <p>So, what would happen if all this hair and nail grooming got too much for us and we decided to give it all up. Would our hair and nails just keep on growing?</p> <p>The answer is yes. The hair on our head grows, on average, <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9917549/">1 centimeter per month</a>, while our fingernails grow an average of just <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC11436330/">over 3 millimetres</a>.</p> <p>When left unchecked, our hair and nails can grow to impressive lengths. Aliia Nasyrova, known as the Ukrainian Rapunzel, holds the world record for the longest locks on a living woman, which measure an <a href="https://www.youtube.com/watch?v=1TdlEIQdVwo&t=81s">impressive 257.33 cm</a>.</p> <p>When it comes to record-breaking fingernails, Diana Armstrong from the United States holds that record <a href="https://www.youtube.com/watch?v=nwql937j-7Q">at 1,306.58 cm</a>.</p> <p>Most of us, however, get regular haircuts and trim our nails – some with greater frequency than others. So why do some people’s hair and nails grow more quickly?</p> <h2>Remind me, what are they made out of?</h2> <p>Hair and nails are made mostly from keratin. Both grow from matrix cells below the skin and grow through different patterns of cell division.</p> <p>Nails grow steadily from the matrix cells, which sit under the skin at the base of the nail. These cells divide, pushing the older cells forward. As they grow, <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC5383514/">the new cells slide</a> along the nail bed – the flat area under the fingernail which looks pink because of its rich blood supply.</p> <p>A hair also starts growing from the matrix cells, eventually forming the visible part of the hair – the shaft. The hair shaft grows from a root that sits under the skin and is wrapped in a sac known as the hair follicle.</p> <p>This sac has a nerve supply (which is why it hurts to pull out a hair), oil-producing glands that lubricate the hair and a tiny muscle that <a href="https://www.ncbi.nlm.nih.gov/books/NBK546248/">makes your hair stand up</a> when it’s cold.</p> <p>At the follicle’s base is the hair bulb, which contains the all-important hair papilla that supplies blood to the follicle.</p> <p>Matrix cells near the papilla divide to produce new hair cells, which then harden and form the hair shaft. As the new hair cells are made, the hair is pushed up above the skin <a href="https://www.jidonline.org/article/S0022-202X(15)41553-2/fulltext">and the hair grows</a>.</p> <p>But the papilla also plays an integral part in regulating hair growth cycles, as it sends signals to the stem cells to move to the base of the follicle and form a hair matrix. Matrix cells then get signals to divide and start a new growth phase.</p> <h2>Unlike nails, our hair grows in cycles</h2> <p>Scientists have identified <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9917549/">four phases of hair growth</a>, the:</p> <ol> <li> <p>anagen or growth phase, which lasts between two and eight years</p> </li> <li> <p>catagen or transition phase, when growth slows down, lasting around two weeks</p> </li> <li> <p>telogen or resting phase, when there is no growth at all. This usually lasts two to three months</p> </li> <li> <p>exogen or shedding phase, when the hair falls out and is replaced by the new hair growing from the same follicle. This starts the process all over again.</p> </li> </ol> <figure class="align-center "><img src="https://images.theconversation.com/files/637402/original/file-20241210-15-gtv259.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/637402/original/file-20241210-15-gtv259.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=308&fit=crop&dpr=1 600w, https://images.theconversation.com/files/637402/original/file-20241210-15-gtv259.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=308&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/637402/original/file-20241210-15-gtv259.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=308&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/637402/original/file-20241210-15-gtv259.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=387&fit=crop&dpr=1 754w, https://images.theconversation.com/files/637402/original/file-20241210-15-gtv259.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=387&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/637402/original/file-20241210-15-gtv259.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=387&fit=crop&dpr=3 2262w" alt="Stages of hair growth graphic" /><figcaption><span class="caption">Hair follicles enter these phases at different times so we’re not left bald.</span> <span class="attribution"><a class="source" href="https://www.shutterstock.com/image-vector/stages-hair-growth-cycle-vector-isolated-2433656865">Mosterpiece/Shutterstock</a></span></figcaption></figure> <p>Each follicle goes through this cycle <a href="https://www.longdom.org/open-access/a-note-on-the-human-hair-follicle-from-the-origin-to-the-death-93871.html?t">10–30 times in its lifespan</a>.</p> <p>If all of our hair follicles grew at the same rate and entered the same phases simultaneously, there would be times when we would all be bald. That doesn’t usually happen: at any given time, only one in ten hairs is in the resting phase.</p> <p>While we lose about <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9917549/">100–150 hairs daily</a>, the average person has <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9917549/">100,000 hairs</a> on their head, so we barely notice this natural shedding.</p> <h2>So what affects the speed of growth?</h2> <p>Genetics is the most significant factor. While hair growth rates vary between individuals, they tend to be <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4201279/">consistent among family members</a>.</p> <p>Nails are also influenced by genetics, as siblings, especially identical twins, tend to have <a href="https://link.springer.com/referenceworkentry/10.1007/978-3-319-26594-0_121-1">similar nail growth rates</a>.</p> <p>But there are also other influences.</p> <p><a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9917549/">Age makes a difference</a> to hair and <a href="https://link.springer.com/referenceworkentry/10.1007/978-3-319-26594-0_121-1">nail</a> growth, even in healthy people. Younger people generally have faster growth rates because of the slowing metabolism and cell division that comes with ageing.</p> <p><a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7432488/">Hormonal changes</a> can have an impact.

While hair and nails are made mostly of keratin, they also contain water, fats and various minerals. As hair and nails keep growing, these minerals need to be replaced.</p> <p>That’s why a balanced diet that includes sufficient nutrients to support your hair and nails is essential for maintaining their health.</p> <p>Nutrient deficiencies may contribute to hair loss and nail breakage by disrupting their growth cycle or weakening their structure. Iron and zinc deficiencies, for example, have both been linked to <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6380979/">hair loss</a> and <a href="https://ijdvl.com/nails-in-nutritional-deficiencies/?t">brittle nails</a>.</p> <p>This may explain why thick hair and strong, well-groomed nails have long been associated with perception of good health and high status.</p> <p>However, not all perceptions are true.</p> <h2>No, hair and nails don’t grow after death</h2> <p>A persistent myth that may relate to <a href="https://www.britannica.com/topic/vampire">the legends of vampires</a> is that hair and nails continue to grow after we die.</p> <p>In reality, they only <em>appear</em> to do so.

How do heat protectants for hair work? A chemistry expert explains

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/daniel-eldridge-1494633">Daniel Eldridge</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a></em></p> <p>Heat can do amazing things to change your hairstyle. Whether you’re using a curling wand to get ringlets, a flat iron to straighten or a hair dryer to style, it’s primarily the heat from these tools that delivers results.</p> <p>This comes with casualties. While your hair is surprisingly tolerant to heat compared with many other parts of your body, it can still only withstand so much. Heat treatment hair appliances frequently operate at over 150°C, with some reportedly <a href="https://www.frontiersin.org/journals/bioengineering-and-biotechnology/articles/10.3389/fbioe.2019.00298/full#B13">reaching</a> <a href="https://www.researchgate.net/publication/289291195_Thermal_degradation_of_hair_I_Effect_of_curling_irons">over 200°C</a>. At these temperatures, your hair can end up fried.</p> <p>Many people use heat protectants, often in the form of sprays, to minimise the damage. So how do these protectants work? To answer that, I first have to explain exactly what heat does to your tresses on the molecular level.</p> <h2>What heat does to your hair</h2> <p>A large proportion of your hair is made up of proteins. There are attractive forces between these proteins, known as hydrogen bonds. These bonds play a big role in dictating the shape of your locks.</p> <p>When you heat up your hair, the total attraction of these hydrogen bonds become weaker, allowing you to more easily re-shape your hair. Then, when it cools back down, these attractions between the proteins are re-established, helping your hair hold its new look until the proteins rediscover their normal structure.</p> <p>The cuticle – the outermost protective layer of your hair – contains overlapping layers of cells that lose integrity when they’re heated, damaging this outer protective layer.</p> <p>Inside that outer layer is the cortex, which is rich in a protein called keratin.</p> <p>Many proteins don’t <a href="https://pubmed.ncbi.nlm.nih.gov/21635854/">hold up structurally</a> after intense heating. Think of cooking an egg – the change you see is a result of the heat altering the proteins in that egg, unravelling them into different shapes and sizes.</p> <p>It’s a <a href="https://library.scconline.org/v049n04/33">similar story</a> when it comes to heating your hair. The proteins in your hair are also susceptible to heat damage, reducing the overall strength and integrity of the hair.</p> <p>Heat can also affect substances called melanin and <a href="https://pubmed.ncbi.nlm.nih.gov/21443842/">tryptophan</a> in your hair, resulting in a change in pigmentation. Heat-damaged hair is <a href="https://pubmed.ncbi.nlm.nih.gov/21635854/">harder to brush</a>.</p> <p>The damage is even more devastating if you use heat styling tools such as <a href="https://labmuffin.com/why-you-should-never-straighten-or-curl-wet-hair/">curling irons or straighteners</a> to <a href="https://library.scconline.org/v062n01/23">heat wet hair</a>, as at the high treatment temperatures, the water soaked up by the fibres can violently evaporate.</p> <p>The result of this is succinctly described by science educator and cosmetic chemist Michelle Wong, also known as <a href="https://labmuffin.com/how-do-heat-protectant-hair-products-work/">Lab Muffin</a>.

Is stress turning my hair grey?

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/theresa-larkin-952095">Theresa Larkin</a>, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a></em></p> <p>When we start to go grey depends a lot on <a href="https://pubmed.ncbi.nlm.nih.gov/36631178/">genetics</a>.</p> <p>Your first grey hairs <a href="https://elifesciences.org/articles/67437">usually appear</a> anywhere between your twenties and fifties. For men, grey hairs <a href="https://pubmed.ncbi.nlm.nih.gov/22077870/">normally</a> start at the temples and sideburns. Women tend to start greying on the hairline, especially at the front.</p> <p>The most <a href="https://pubmed.ncbi.nlm.nih.gov/36631178/">rapid greying</a> usually happens between ages 50 and 60. But does anything we do speed up the process? And is there anything we can do to slow it down?</p> <p>You’ve probably heard that plucking, dyeing and stress can make your hair go grey – and that redheads don’t. Here’s what the science says.</p> <h2>What gives hair its colour?</h2> <p>Each strand of hair is produced by a hair follicle, a tunnel-like opening in your skin. Follicles contain two different kinds of <a href="https://www.sciencedirect.com/science/article/pii/S1534580720301040">stem cells</a>:</p> <ul> <li>keratinocytes, which produce <a href="https://my.clevelandclinic.org/health/body/23204-keratin">keratin</a>, the protein that makes and regenerates hair strands</li> <li>melanocytes, which produce <a href="https://my.clevelandclinic.org/health/body/22615-melanin">melanin</a>, the pigment that colours your hair and skin.</li> </ul> <p>There are <a href="https://www.ncbi.nlm.nih.gov/books/NBK459156/">two main types</a> of melanin that <a href="https://pubmed.ncbi.nlm.nih.gov/36631178/">determine hair colour</a>. Eumelanin is a black-brown pigment and pheomelanin is a red-yellow pigment.</p> <p>The <a href="https://theconversation.com/studying-the-complex-genetics-behind-hair-colour-reveals-how-melanin-affects-us-171088#:%7E:text=Eumelanin%20is%20also%20known%20as%20the%20brown-black%20pigment%2C,is%20due%20to%20low%20amounts%20of%20both%20pigments.">amount of the different pigments</a> determines hair colour. Black and brown hair has mostly eumelanin, red hair has the most pheomelanin, and blonde hair has just a small amount of both.</p> <h2>So what makes our hair turn grey?</h2> <p>As we age, it’s normal for cells to become less active. In the hair follicle, this means stem cells produce less melanin – turning our hair grey – and less keratin, causing hair thinning and loss.</p> <p>As less melanin is produced, there is less pigment to give the hair its colour. Grey hair has very little melanin, while white hair has none left.</p> <p>Unpigmented hair <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6290285/">looks grey</a>, white or silver because light reflects off the keratin, which is pale yellow.</p> <p>Grey hair is thicker, coarser and stiffer than hair with pigment. This is because the shape of the hair follicle becomes <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6290285/">irregular</a> as the stem cells change with age.</p> <p>Interestingly, grey hair also grows faster than pigmented hair, but it <a href="https://elifesciences.org/articles/67437">uses more energy</a> in the process.</p> <h2>Can stress turn our hair grey?</h2> <p>Yes, stress can <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6290285/">cause your hair to turn grey</a>. This happens when <a href="https://faseb.onlinelibrary.wiley.com/doi/epdf/10.1096/fj.05-4039fje">oxidative stress</a> damages hair follicles and stem cells and <a href="https://www.frontiersin.org/journals/physiology/articles/10.3389/fphys.2022.839859/full">stops them producing</a> melanin.</p> <p>Oxidative stress is an imbalance of too many damaging free radical chemicals and not enough protective antioxidant chemicals in the body. It can be <a href="https://pubmed.ncbi.nlm.nih.gov/36631178/">caused by</a> psychological or emotional stress as well as autoimmune diseases.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/22077870/">Environmental factors</a> such as exposure to UV and pollution, as well as smoking and some drugs, can also play a role.</p> <p>Melanocytes are <a href="https://elifesciences.org/articles/67437">more susceptible to damage</a> than keratinocytes because of the complex steps in melanin production. This explains why ageing and stress usually cause hair greying before hair loss.</p> <p>Scientists have been able to link less pigmented sections of a hair strand to <a href="https://elifesciences.org/articles/67437">stressful events in a person’s life</a>. In younger people, whose stems cells still produced melanin, colour returned to the hair after the stressful event passed.</p> <h2>4 popular ideas about grey hair – and what science says</h2> <p><strong>1. Does plucking a grey hair make more grow back in its place?</strong></p> <p>No. When you pluck a hair, you might notice a small bulb at the end that was attached to your scalp. This is the <a href="https://my.clevelandclinic.org/health/body/23435-hair-follicle">root</a>. It grows from the hair follicle.</p> <p>Plucking a hair pulls the root out of the follicle. But the follicle itself is the opening in your skin and can’t be plucked out. Each hair follicle can only grow a single hair.</p> <p>It’s possible frequent plucking could make your hair <a href="https://pubmed.ncbi.nlm.nih.gov/18713071/">grey earlier</a>, if the cells that produce melanin are damaged or exhausted from too much regrowth.</p> <p><strong>2. Can my hair can turn grey overnight?</strong></p> <p>Legend says Marie Antoinette’s hair went <a href="https://www.healthline.com/health/marie-antoinette-syndrome">completely white</a> the night before the French queen faced the guillotine – but this is a myth.</p> <p>Melanin in hair strands is chemically stable, meaning it can’t transform instantly.</p> <p>Acute psychological stress does rapidly deplete melanocyte stem cells <a href="https://www.nature.com/articles/s41586-020-1935-3">in mice</a>. But the effect doesn’t show up immediately. Instead, grey hair becomes visible as the strand grows – at a rate of <a href="https://www.medicalnewstoday.com/articles/326764">about 1 cm per month</a>.</p> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7432488/">Not all hair</a> is in the growing phase at any one time, meaning it can’t all go grey at the same time.</p> <p><strong>3. Will dyeing make my hair go grey faster?</strong></p> <p>This <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9953601/">depends on the dye</a>.</p> <p>Temporary and semi-permanent dyes should not cause early greying because they just coat the hair strand without changing its structure. But permanent products cause a chemical reaction with the hair, using an oxidising agent such as hydrogen peroxide.</p> <p>Accumulation of hydrogen peroxide and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10232955/">other hair dye chemicals</a> in the hair follicle <a href="https://pubmed.ncbi.nlm.nih.gov/36631178/">can damage</a> melanocytes and keratinocytes, which can cause greying and hair loss.</p> <p><strong>4. Is it true redheads don’t go grey?</strong></p> <p>People with red hair also lose melanin as they age, but differently to those with black or brown hair.</p> <p>This is because the red-yellow and black-brown pigments are chemically different.</p> <p>Producing the brown-black pigment eumelanin is more complex and <a href="https://onlinelibrary.wiley.com/doi/full/10.1034/j.1600-0749.2002.02017.x">takes more energy</a>, making it more susceptible to damage.</p> <p>Producing the red-yellow pigment (pheomelanin) causes <a href="https://www.sciencedirect.com/science/article/pii/S016953472030375X">less oxidative stress</a>, and is more simple. This means it is easier for stem cells to continue to produce pheomelanin, even as they reduce their activity with ageing.</p> <p>With ageing, red hair tends to fade into strawberry blonde and silvery-white. Grey colour is due to less eumelanin activity, so is more common in those with black and brown hair.</p> <p>Your genetics determine when you’ll start going grey. But you may be able to avoid premature greying by staying healthy, reducing stress and avoiding smoking, too much alcohol and UV exposure.</p> <p>Eating <a href="https://www.healthline.com/health/melanin-in-hair#b-6-and-b-12">a healthy diet</a> may also help because vitamin B12, copper, iron, calcium and zinc all <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6290285/">influence melanin production and hair pigmentation</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/239100/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/theresa-larkin-952095">Theresa Larkin</a>, Associate Professor of Medical Sciences, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How to revive your curls without paying salon prices

<p>Maintaining curly hair takes a lot of time and effort and sometimes no matter what you do, the frizz just cannot be tamed. </p> <p>While getting your hair done at the salon can be a treat, having to pay salon prices to get softness, shine and definition for your curls is just not sustainable in the long run. </p> <p>Enter <a href="https://www.johnfrieda.com/en-au/home/" target="_blank" rel="noopener">John Frieda</a>'s newest Frizz Ease Miraculous Recovery range, which is now infused with repairing ceramides designed to transform frizzy and damaged hair. </p> <p>The Miraculous Recovery Repairing shampoo and conditioner are two of my personal faves, as I could feel the difference in how soft my hair felt after the first use.</p> <p>Not only are the products safe for colour-treated hair, they also made my curls more manageable and easy to style, with the effects lasting for two days, which is amazing considering how quickly my curls can go limp. </p> <p>I also loved how subtle the scent was, and found the most effective way of applying the conditioner was to comb it through my hair with a detangling brush in the shower, as it helps distribute the product evenly. </p> <p>While different curls all need slightly different care, I found the shampoo provided the perfect balance of cleaning build-up on my hair without leaving it dry or flaky. </p> <p>The star of the range was definitely the All-in-1 extra strength serum, which provided extra protection for my colour-treated and chemically treated hair. I love that you can apply this product through wet or dry hair, and it was the perfect way to revive my curls. </p> <p>The Finishing Creme was a bit too thick for my fine, curly hair, but for those with tighter curls or those looking for some extra moisture during more humid days, a light layer of the product would surely tame any flyaways or frizz. </p> <p>With most of their products retailing for around $20 it is an affordable solution to bringing life back into colour-treated and damaged curls. The product can be found in all major supermarkets and pharmacies across <a href="https://www.chemistwarehouse.com.au/shop-online/5571/john-frieda-haircare" target="_blank" rel="noopener">AU</a> and <a href="https://www.chemistwarehouse.co.nz/shop-online/5571/john-frieda-haircare" target="_blank" rel="noopener">NZ</a>. </p> <p><em>Images: Supplied</em></p> <p> </p>

Some organisations, such as <a href="https://obesitycanada.ca/guidelines/nutrition/">Obesity Canada</a>, have included HAES in their <a href="https://pubmed.ncbi.nlm.nih.gov/32753461/">guidelines for obesity treatment</a>.</p> <h2>How does it compare with weight-focused treatments?</h2> <p>We conducted a <a href="https://pubmed.ncbi.nlm.nih.gov/38563692/">systematic review and meta-analysis</a> of all the research studies published until November 2022 that had used HAES-based programs.</p> <p>Across 19 scientific papers, we compared the outcomes of people living in larger bodies who used HAES-based programs <a href="https://pubmed.ncbi.nlm.nih.gov/38563692/">with</a>:</p> <ul> <li>conventional weight loss programs (six studies)</li> <li>people on waiting lists receiving no treatment at all (six studies)</li> <li>groups where people received weekly social support in groups (four studies).</li> </ul> <p>We evaluated the program’s impact on appetite, weight, physical health measurements including cholesterol and blood pressure, and also wellbeing and mental health.</p> <p>Our analysis found HAES interventions were beneficial in reducing susceptibility to hunger more than other approaches, meaning people had less subjective perceptions of hunger or eating in response to emotions.</p> <p>However, compared to control interventions, HAES did not show superior results for improving any other physical health outcome – weight loss, blood cholesterol levels, blood pressure – or wellbeing or mental health outcomes.</p> <p>Given the results to date, the choice about whether to use a HAES-based approach (or not) will depend on each person’s preference, needs and goals.</p> <h2>Don’t get your health advice from influencers</h2> <p>While HAES has been used in clinical practice for many years, some United States and Canadian anti-diet practitioner’s motives have been scrutinised because of their links <a href="https://www.washingtonpost.com/wellness/2024/04/03/diet-culture-nutrition-influencers-general-mills-processed-food/">with processed food companies</a>.</p> <p>The spotlight was put on the <a href="https://nutritionbycarrie.com/2024/04/washington-post-dietitians.html">very small number</a> of dietitian “influencers” (roughly 20 from a membership of more than 80,000 dietitians in the US and Canada) promoting “eat what you feel like” and discouraging people from making weight loss attempts, under the banner of HAES. They failed to mention they were being paid to promote products sold by food, beverage or supplement companies.</p> <p>US <a href="https://nutritionbycarrie.com/2024/04/washington-post-dietitians.html">author and dietitian Carrie Dennet</a> urges people to not look to influencers for health advice. Instead, seek non-judgemental health care from your GP.</p> <h2>What might treatment look like?</h2> <p>When improving your health is a treatment goal, a good place to start your journey is to have a health check-up with your doctor, as well as to assess your relationship with food.</p> <p>A healthy relationship with food means being able to eat appropriate amounts and variety of foods to meet your nutritional, health and wellbeing goals. This might include strategies such as:</p> <ul> <li>keeping a <a href="https://theconversation.com/what-does-having-a-good-relationship-with-food-mean-4-ways-to-know-if-youve-got-one-202622">food mood diary</a></li> <li>reflecting on factors that influence your eating</li> <li>practising <a href="https://theconversation.com/thinking-youre-on-a-diet-is-half-the-problem-heres-how-to-be-a-mindful-eater-99207">mindful eating</a></li> <li>learning about nutrient needs</li> <li>focusing on food enjoyment and the pleasure that comes from preparing, sharing and eating with others.</li> </ul> <p>If you need more help to develop this, ask your doctor to refer you to a health practitioner who can assist.</p> <h2>What if your goal is weight loss?</h2> <p>When it comes to medical nutrition therapy to treat weight-related health conditions, such as high blood pressure and type 2 diabetes, the approach will depend on individual needs and expectations.</p> <p>Broadly, there are three graded energy intake target levels:</p> <ol> <li> <p>a reduced-energy diet where the goal is to lower energy intake by 2,000 to 4,000 kilojoules (kJ) per day by identifying food substitutions, like swapping soft drinks and other sugar-sweetened drinks for zero or diet versions or water.</p> </li> <li> <p>a <a href="https://theconversation.com/health-check-whats-the-best-diet-for-weight-loss-21557">low-energy diet</a>, which uses an energy intake goal in the range of 4,200-5,000 kJ, up to 7,000 kJ per day depending on an individual’s energy expenditure.</p> </li> <li> <p>the most restricted regime is a <a href="https://theconversation.com/health-check-whats-the-best-diet-for-weight-loss-21557">very low-energy diet</a>, has an energy intake target less than 2,500 kJ/day, achieved using formulated meal replacement products.</p> </li> </ol> <p>The aim of a <a href="https://theconversation.com/health-check-whats-the-best-diet-for-weight-loss-21557">very low-energy diet</a> is to facilitate rapid weight loss when this is essential to improve health acutely such as poorly controlled type 2 diabetes. Such a diet should be used under supervision by your doctor and dietitian.</p> <p>When selecting an initial <a href="https://theconversation.com/health-check-whats-the-best-diet-for-weight-loss-21557">strategy</a>, seek a balance between energy intake goals and your ability to stick to it. Your approach may change over time as your health needs change.</p> <p>If you need personalised nutrition advice, ask for a referral to an accredited practising dietitian. The <a href="https://member.dietitiansaustralia.org.au/Portal/Portal/Search-Directories/Find-a-Dietitian.aspx">register of service providers though Dietitians Australia</a> allows you to view their expertise and location.</p> <p>Regardless of whether your practitioner uses a HAES approach or not, your health providers should always treat you with respect and address your personal health and wellbeing.<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/234376/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/clare-collins-7316">Clare Collins</a>, Laureate Professor in Nutrition and Dietetics, <a href="https://theconversation.com/institutions/university-of-newcastle-1060">University of Newcastle</a>; <a href="https://theconversation.com/profiles/erin-clarke-1314081">Erin Clarke</a>, Postdoctoral Researcher, Nutrition and Dietetics, <a href="https://theconversation.com/institutions/university-of-newcastle-1060">University of Newcastle</a>; <a href="https://theconversation.com/profiles/jordan-stanford-1631336">Jordan Stanford</a>, Post Doctorate Fellow, Nutrition and Dietetics, <a href="https://theconversation.com/institutions/university-of-newcastle-1060">University of Newcastle</a>, and <a href="https://theconversation.com/profiles/maria-gomez-martin-1218567">María Gómez Martín</a>, Dietitian and early career researcher, <a href="https://theconversation.com/institutions/university-of-newcastle-1060">University of Newcastle</a></em></p> <p><em>Image </em><em>credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"Shockingly irresponsible": Elle Macpherson slammed for "holistic" cancer treatment

<p>Elle Macpherson has been subjected to widespread backlash online after revealing she opted for a "holistic" cancer treatments. </p> <p>The 60-year-old supermodel has revealed in her book, <em>Elle: Life, Lessons, and Learning to Trust Yourself</em>, that at the age of 53, she was <a href="https://oversixty.com.au/health/caring/elle-macpherson-reveals-secret-battle-with-cancer" target="_blank" rel="noopener">diagnosed</a> with breast cancer following a lumpectomy. </p> <p>She went on to share how she shunned the advice of doctors who recommended a mastectomy with radiation, chemotherapy, hormone therapy, plus reconstruction of her breast to fight the illness, deciding to forge her own path of "holistic wellness" to beat the disease without the use on conventional medicines. </p> <p>Since going public with her decision, Macpherson has been slammed online, with other cancer sufferers saying her comments are irresponsible and dangerous. </p> <p>One person wrote on X, "This is shockingly irresponsible from Elle Macpherson. She was lucky that clearly the lumpectomy removed all the cancerous cells and it hadn't spread, but implying she 'cured' cancer holistically is reckless beyond belief."</p> <p>Another person said, "Going through my own breast cancer battle atm I wish I there was a 'holistic approach' but there’s not... What I do have is different options & I’ll take whatever treatments both my oncologist’s offer me to ensure I live a longer life to be with my husband and kids."</p> <p>A third person added, "A lumpectomy isn't holistic, and she wouldn't have even known about the cancer 'to treat holistically' had she not gone the conventional medical route in the first place."</p> <p>Many took aim at the dangerous rhetoric, with one person saying, "There is real toxic wellness/positivity culture out there at the moment that is both unnerving and dangerous," while another added, "As a survivor, I am absolutely livid. This nonsense costs lives."</p> <p><em>Image credits: Instagram </em></p>

What is type 1.5 diabetes? It’s a bit like type 1 and a bit like type 2 – but it’s often misdiagnosed

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/emily-burch-438717">Emily Burch</a>, <a href="https://theconversation.com/institutions/southern-cross-university-1160">Southern Cross University</a> and <a href="https://theconversation.com/profiles/lauren-ball-14718">Lauren Ball</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a></em></p> <p>While you’re likely familiar with type 1 and type 2 diabetes, you’ve probably heard less about type 1.5 diabetes.</p> <p>Also known as latent autoimmune diabetes in adults (LADA), type 1.5 diabetes has features of <a href="https://diabetesjournals.org/diabetes/article/69/10/2037/16062/Management-of-Latent-Autoimmune-Diabetes-in-Adults">both type 1 and type 2 diabetes</a>.</p> <p>More people became aware of this condition after <a href="https://www.imdb.com/name/nm0004726/">Lance Bass</a>, best known for his role in the iconic American pop band NSYNC, <a href="https://www.foxnews.com/health/pop-singer-lance-bass-type-1-5-diabetes-know-disease">recently revealed</a> he has it.</p> <p>So, what is type 1.5 diabetes? And how is it diagnosed and treated?</p> <h2>There are several types of diabetes</h2> <p>Diabetes mellitus is a group of conditions that arise when the levels of glucose (sugar) in our blood are higher than normal. There are actually <a href="https://diabetesjournals.org/care/article/37/Supplement_1/S81/37753/Diagnosis-and-Classification-of-Diabetes-Mellitus">more than ten types</a> of diabetes, but the <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(23)01301-6/fulltext">most common</a> are type 1 and type 2.</p> <p>Type 1 diabetes is an <a href="https://diabetesjournals.org/care/article/44/11/2589/138492/The-Management-of-Type-1-Diabetes-in-Adults-A">autoimmune condition</a> where the body’s immune system attacks and destroys the cells in the pancreas that make the hormone insulin. This leads to very little or no insulin production.</p> <p>Insulin is important for moving glucose from the blood into our cells to be used for energy, which is why people with type 1 diabetes need <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6995794/">insulin medication daily</a>. Type 1 diabetes usually <a href="https://www.nature.com/articles/s41390-024-03107-5">appears</a> in children or young adults.</p> <p>Type 2 diabetes is not an autoimmune condition. Rather, it happens when the body’s cells become resistant to insulin over time, and the pancreas is no longer able to make enough insulin to <a href="https://diabetesjournals.org/care/article/47/Supplement_1/S20/153954/2-Diagnosis-and-Classification-of-Diabetes">overcome this resistance</a>. Unlike type 1 diabetes, people with type 2 diabetes still produce some insulin.</p> <p>Type 2 is more common in adults but is <a href="https://www.sciencedirect.com/science/article/abs/pii/S1871402121002733">increasingly</a> seen in children and young people. Management <a href="https://www.racgp.org.au/getattachment/41fee8dc-7f97-4f87-9d90-b7af337af778/Management-of-type-2-diabetes-A-handbook-for-general-practice.aspx">can include</a> behavioural changes such as nutrition and physical activity, as well as oral medications and insulin therapy.</p> <h2>How does type 1.5 diabetes differ from types 1 and 2?</h2> <p>Like type 1 diabetes, type 1.5 occurs when the immune system attacks the pancreas cells that make insulin. But people with type 1.5 often don’t need insulin <a href="https://diabetesjournals.org/diabetes/article/69/10/2037/16062/Management-of-Latent-Autoimmune-Diabetes-in-Adults">immediately</a> because their condition develops more slowly. Most people with type 1.5 diabetes will need to use insulin within <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5111528/">five years</a> of diagnosis, while those with type 1 typically require it from diagnosis.</p> <p>Type 1.5 diabetes is usually diagnosed in people <a href="https://diabetesjournals.org/diabetes/article/69/10/2037/16062/Management-of-Latent-Autoimmune-Diabetes-in-Adults">over 30</a>, likely due to the slow progressing nature of the condition. This is older than the typical age for type 1 diabetes but younger than the usual diagnosis age for type 2.</p> <p>Type 1.5 diabetes shares <a href="https://www.nature.com/articles/nrendo.2017.99">genetic and autoimmune risk factors</a> with type 1 diabetes such as specific gene variants. However, evidence has also shown it may be influenced by lifestyle factors such as <a href="https://pubmed.ncbi.nlm.nih.gov/29589073/">obesity</a> and <a href="https://www.frontiersin.org/journals/physiology/articles/10.3389/fphys.2019.00320/full">physical inactivity</a> which are more commonly associated with type 2 diabetes.</p> <h2>What are the symptoms, and how is it treated?</h2> <p>The symptoms of type 1.5 diabetes are highly variable between people. Some have no symptoms at all. But generally, people may experience the following <a href="https://www.ncbi.nlm.nih.gov/books/NBK557897/">symptoms</a>:</p> <ul> <li>increased thirst</li> <li>frequent urination</li> <li>fatigue</li> <li>blurred vision</li> <li>unintentional weight loss.</li> </ul> <p>Typically, type 1.5 diabetes is <a href="https://diabetesjournals.org/diabetes/article/69/10/2037/16062/Management-of-Latent-Autoimmune-Diabetes-in-Adults">initially treated</a> with oral medications to keep blood glucose levels in normal range. Depending on their glucose control and the medication they are using, people with type 1.5 diabetes may need to monitor their blood glucose levels regularly throughout the day.</p> <p>When average blood glucose levels increase beyond normal range even with oral medications, treatment may progress to insulin. However, there are <a href="https://www.frontiersin.org/journals/endocrinology/articles/10.3389/fendo.2022.959011/full">no universally accepted</a> management or treatment strategies for type 1.5 diabetes.</p> <h2>Type 1.5 diabetes is often misdiagnosed</h2> <p>Lance Bass said he was initially diagnosed with <a href="https://www.healthline.com/health-news/lance-bass-misdiagnosed-diabetes">type 2 diabetes</a>, but later learned he actually has type 1.5 diabetes. This is <a href="https://journals.lww.com/jaanp/abstract/2009/03000/latent_autoimmune_diabetes_of_adulthood__lada___an.4.aspx">not entirely uncommon</a>. Estimates suggest type 1.5 diabetes is misdiagnosed as type 2 diabetes <a href="https://www.sciencedirect.com/science/article/abs/pii/S1043276018301292">5–10% of the time</a>.</p> <p>There are a few possible reasons for this.</p> <p>First, accurately diagnosing type 1.5 diabetes, and distinguishing it from other types of diabetes, requires special <a href="https://journals.lww.com/jaanp/abstract/2009/03000/latent_autoimmune_diabetes_of_adulthood__lada___an.4.aspx">antibody tests</a> (a type of blood test) to detect autoimmune markers. Not all health-care professionals necessarily order these tests routinely, either due to cost concerns or because they may not consider them.</p> <p>Second, type 1.5 diabetes is commonly found in adults, so doctors might wrongly assume a person has developed type 2 diabetes, which is more common in this age group (whereas type 1 diabetes usually affects children and young adults).</p> <p>Third, people with <a href="https://diabetesjournals.org/diabetes/article/69/10/2037/16062/Management-of-Latent-Autoimmune-Diabetes-in-Adults">type 1.5 diabetes</a> often initially make enough insulin in the body to manage their blood glucose levels without needing to start insulin medication. This can make their condition appear like type 2 diabetes, where people also produce some insulin.</p> <p>Finally, because type 1.5 diabetes has <a href="https://www.ncbi.nlm.nih.gov/books/NBK557897/">symptoms</a> that are similar to type 2 diabetes, it may initially be treated as type 2.</p> <h2>We’re still learning about type 1.5</h2> <p>Compared with type 1 and type 2 diabetes, there has been much less research on how common type 1.5 diabetes is, especially in <a href="https://www.sciencedirect.com/science/article/abs/pii/S1043276018301292">non-European populations</a>. In 2023, it was estimated type 1.5 diabetes represented <a href="https://pubmed.ncbi.nlm.nih.gov/37428296/">8.9%</a> of all diabetes cases, which is similar to type 1. However, we need more research to get accurate numbers.</p> <p>Overall, there has been a limited awareness of type 1.5 diabetes and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10683931/">unclear diagnostic criteria</a> which have slowed down our understanding of this condition.</p> <p>A misdiagnosis can be stressful and confusing. For people with type 1.5 diabetes, being misdiagnosed with type 2 diabetes might mean they don’t get the insulin they need in a timely manner. This can lead to worsening health and a greater likelihood of complications down the road.</p> <p>Getting the right diagnosis helps people receive the most appropriate treatment, save money, and reduce <a href="https://diabetesjournals.org/diabetes/article/73/Supplement_1/55-OR/155112/55-OR-Diabetes-Distress-among-Persons-Living-with">diabetes distress</a>. If you’re experiencing symptoms you think may indicate diabetes, or feel unsure about a diagnosis you’ve already received, monitor your symptoms and chat with your doctor.<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/237041/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/emily-burch-438717">Emily Burch</a>, Accredited Practising Dietitian and Lecturer, <a href="https://theconversation.com/institutions/southern-cross-university-1160">Southern Cross University</a> and <a href="https://theconversation.com/profiles/lauren-ball-14718">Lauren Ball</a>, Professor of Community Health and Wellbeing, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a></em></p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Why IBD is so hard to treat – and how scientists are making progress

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/falk-hildebrand-1490022">Falk Hildebrand</a>, <a href="https://theconversation.com/institutions/quadram-institute-5557">Quadram Institute</a>; <a href="https://theconversation.com/profiles/katarzyna-sidorczuk-1490026">Katarzyna Sidorczuk</a>, <a href="https://theconversation.com/institutions/quadram-institute-5557">Quadram Institute</a>, and <a href="https://theconversation.com/profiles/wing-koon-1490274">Wing Koon</a>, <a href="https://theconversation.com/institutions/quadram-institute-5557">Quadram Institute</a></em></p> <p>Inflammatory bowel disease (IBD) is a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5478758/">life altering</a> chronic illness that is <a href="https://bmjopen.bmj.com/content/13/3/e065186">rising dramatically globally</a>. It is stubbornly difficult to treat, and many people find the treatments we have just don’t work for them.</p> <p>Over the last 30 years, there has been almost a 50% increase in cases – now affecting around 5 million people. Not to be confused with irritable bowel syndrome (IBS) which is a condition that affects the digestive system, IBD is more serious. It is the term for two severe illnesses called <a href="https://www.nhs.uk/conditions/crohns-disease/">Crohn’s disease</a> and <a href="https://www.nhs.uk/conditions/ulcerative-colitis/">ulcerative colitis</a>. More women are <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9958616/#:%7E:text=Male%20predominance%20in%20IBD.,%2C%202.32%3A1%20in%20CD.">diagnosed with Crohn’s disease</a> while more men are affected by ulcerative colitis.</p> <p>People with IBD can experience a variety of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4106026/">symptoms</a>, ranging from diarrhoea and blood in the stool, to weight loss and belly aches. On paper, this may sound no worse than mild food poisoning, however, this is no normal stomach upset.</p> <p>Experiences are often extreme; people with IBD can suffer excruciating pain and in some cases, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9963331/">require surgery</a> to remove parts of the bowel. This is done by redirecting the bowel to a hole in the abdomen, where faeces are collected in a <a href="https://www.nhs.uk/conditions/colostomy/">colostomy bag</a>.</p> <p>However, we still don’t fully understand the cause of IBD.</p> <h2>The impact of inflammation</h2> <p>The main symptom of IBD is excessive and uncontrolled <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5805548/">inflammation</a> – normally a sign of the body fighting off an infection. Although inflammation is an important aspect of our immune system, in IBD it is happening when the body is not under attack. Since we don’t know what causes this over-the-top reaction, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8720971/">treatments</a> are limited to managing the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3964397/">derailed immune system</a>.</p> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8373857/">Inflammation is controlled</a> by cell signalling. Our cells detect bacteria using receptors that attach to parts of bacteria. This activates the receptor, causing it to send a signal to proteins, and each protein sends on more signals, creating a signal cascade. This is what tells the body it’s under attack.</p> <p>Many treatments follow the strategy of intercepting signals and preventing the signal cascade from starting. However, they are <a href="https://journals.lww.com/co-gastroenterology/abstract/2022/07000/management_of_refractory_inflammatory_bowel.6.aspx">not effective</a> for many people.</p> <p>Scientists are trying to target a different protein network, called <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2924159/">NOD2</a>, that often goes haywire in people with IBD but is not targeted by current treatments. A protein, called <a href="https://www.frontiersin.org/articles/10.3389/fphar.2021.650403/full">RIPK2</a>, seems like a promising target since it is <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6939834/">only found</a> in this network. Researchers from the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10485824/">European Molecular Biology Laboratory</a> are investigating its structure to help scientists design a new medication that will block the signals from this protein.</p> <h2>Importance of the microbiome</h2> <p>Another inspiration for new treatments comes from the bacteria residing in our guts. This community of bacteria, called the gut microbiome, has been associated with <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6314516/">all sorts of health conditions</a> ranging from asthma to obesity.</p> <p>Gut bacteria work closely with our bodies and play a vital role in digesting food and managing our <a href="https://www.nature.com/articles/s41422-020-0332-7">immune system</a>. In a healthy person, there is a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4143175/">fine balance</a> between gut bacteria and the immune system. Disruption of this balance can lead to disease, starting from minor discomfort to more severe, long-term conditions.</p> <p>Scientists are trying to understand how our bodies interact with gut bacteria, and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8102608/">what changes</a> when people develop IBD.</p> <p>The gut microbiome is an ecosystem. Just like a forest has animals eating different things, microbes can form a <a href="https://www.frontiersin.org/articles/10.3389/fevo.2019.00153/full">food web</a>. Some bacteria will use up one type of food, while others feed off other foods. Some rely on the waste of other bacteria after they’ve eaten. It is now believed that disruption to the gut microbiome is a characteristic of IBD and contributes to its development and progression.</p> <p>It’s a chicken and egg situation. Is there a change in the bacteria and food web that alters our bodies? Or does something else in the body, like our immune system, change the food web, subsequently limiting which bacteria can grow? Scientists aren’t sure of the answer.</p> <p>Instead of trying to figure out what happens first, a team at the <a href="https://www.nature.com/articles/s41467-023-42112-w">Hudson Institute of Medical Research</a> in Australia have focused on investigating which interactions in the food web are the most affected in IBD. This could help scientists to prioritise certain gut bacteria, or their food source, to restore the balance in the microbiome and improve patients’ symptoms.</p> <p>Hopefully, this specialised targeting of the microbiome will lead to more effective and longer lasting treatments.</p> <p>Although we have a long way to go before these ideas for treatments can become a reality, it is a step in the right direction. Targeting a new signalling pathway will hopefully control the inflammation in more patients. And studying the microbiome may reveal how we can reverse changes associated with IBD.</p> <p>Since they are key features of IBD, these developments could allow doctors to stop the disease in the early stages and reduce complications.<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/218307/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/falk-hildebrand-1490022">Falk Hildebrand</a>, Researcher in Bioinformatician, <a href="https://theconversation.com/institutions/quadram-institute-5557">Quadram Institute</a>; <a href="https://theconversation.com/profiles/katarzyna-sidorczuk-1490026">Katarzyna Sidorczuk</a>, Research Scientist in Metagenomics, <a href="https://theconversation.com/institutions/quadram-institute-5557">Quadram Institute</a>, and <a href="https://theconversation.com/profiles/wing-koon-1490274">Wing Koon</a>, PhD student in Bioinformatics, <a href="https://theconversation.com/institutions/quadram-institute-5557">Quadram Institute</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Expert reveals why you shouldn’t use hotel hair dryers

<p dir="ltr">An expert has shared why you should avoid using hair dryers that are provided in hotels. </p> <p dir="ltr">Many travellers rely on these handy devices that are often found in bathroom drawers in hotels, instead of packing your own hair dryer that can often take up valuable luggage space. </p> <p dir="ltr">However, trichologist Jacqui McIntosh, who focuses on diseases related to the scalp and hair, said travellers should avoid these appliances at all costs. </p> <p dir="ltr">According to the expert, there's a high chance there are bacteria and germs lurking inside the hair dryer that have been passed between hotel guests.</p> <p dir="ltr">"Using a hairdryer riddled with bacteria and germs does pose health risks and can be detrimental to your hair health," she told <em>The Mirror</em>. </p> <p dir="ltr">McIntosh says when the microorganisms inside a hairdryer make their way onto your hair and scalp, "they can spark infections and irritations, disrupting your hair follicles and slowing down healthy growth."</p> <p dir="ltr">Even without the worry of bacteria and germs, there's a chance of dust and mould lurking inside the appliance, which she says are "troublemakers for your scalp".</p> <p dir="ltr">"Neglected hair dryers are time bombs waiting to go off. Debris buildup inside the device spells overheating, increasing the risk of singeing your hair or scalp," she explained.</p> <p dir="ltr">McIntosh also clarified that, as pointed out in a 2009 study, hairdryers are one of the handful of items that are missed by hotel cleaning staff, so next time you’re staying in a hotel, probably best to bring your own hair dryer. </p> <p dir="ltr"><em>Image credits: Shutterstock </em></p> <p> </p>

Championing confidence at the salon for those facing cancer

<div title="Page 1"> <div> <div> <p>When it comes to facing cancer, it's can often be hard to find support and understanding from people when your physical appearance can be changing. A salon day can do the world of good for anyone, especially for people going through a hard time. But for those dealing with cancer, their wants and needs at the hairdresser can be different than other clientele.</p> <p>Thankfully, <a href="https://lgfb.org.au" target="_blank" rel="noopener">Look Good Feel Better Australia</a> are here to support those on their cancer journey to look their best in the face of their health battle, </p> <p>From August 1st, the team at Look Good Feel better Australia have launched their latest initiative; <a href="https://www.styleforcancer.org.au" target="_blank" rel="noopener">Style For Cancer</a>. Created to unite the beauty, grooming and styling industry as a force for good, the initiative will help raise vital funds for the Look Good Feel BeIer program while giving service providers the opportunity to build their knowledge and position as part of an invaluable support system to those undergoing treatment for cancer.</p> <p>The new initiative caters to both the consumer, or the “Style Seeker”, and the expert, known as the “Style Maker”.</p> <p>Style Makers who sign up to take part in Style For Cancer will be provided with materials to help them better understand the common side effects of cancer treatment, and advice on language to use and avoid, in order to more sensitively and compassionately support their clients as they navigate diagnosis and treatment. </p> <p>The directory of participating Style Makers will be available to all Style Seekers, allowing them to choose salons and service providers who have a better understanding of what they may be experiencing if they are undergoing cancer treatment, while also knowing they are choosing a business who is consciously supporting the important work of the Look Good Feel Better program.</p> <p>General Manager of Look Good Feel Better, Carol Kavurma, shares the passion and excitement around the launch of Style For Cancer which will provide a way for the industry to feel more empowered while further connecting with their local communities.</p> <p>“Having 34 years of incredible knowledge behind us, when looking at the Australian beauty, grooming and style industries, we saw an opportunity to make salon appointments less daunting and more comfortable for those undergoing life altering treatments,” said Carol.</p> <p>“Everybody deserves to feel excited and uplifted after a trip to the hairdresser, nail salon or when sitting in the makeup chair – it’s the whole premise of the Look Good Feel Better program – and those undergoing cancer treatment are no different."</p> <p>“To help service providers – or Style Makers - feel the same excitement and confidence when working with their clients makes the Style for Cancer initiative even more important, and one we hope will be welcomed with open arms within the industry and the broader community,” she said.</p> <p>Look Good Feel Better program participant and Style Seeker, Jodie Strong, who underwent an array of cancer treatments says the physical and mental sensitivities during treatment are challenging, and while there is some support for mental recovery, the information and resources available for physical recovery are far less abundant.</p> <p>“During treatment, particularly chemo, I didn’t have the confidence to book in any services. After my active treatments were complete, while most service providers were sensitive and careful in the way they approached me and their language with me, I was usually the one to share what worked and didn’t work for me in my recovery rather than the salon or styling professional. I think that’s from a lack of awareness in the industry around this area, so as I was never quite sure what the right thing to do or not to do was,” explains Jodie.</p> </div> </div> </div> <div title="Page 2"> <div> <div> <p>“An important part of recovery from cancer is your feelings of self-worth and being able to take care of your body both mentally and physically. There are a lot of resources in the area of mental recovery, however not as much is available on the physical side of things."</p> <p>“Style For Cancer is an important initiative to bring awareness and some education to the physical side of recovery and help patients both during and post-treatment access services to help them feel more comfortable in their recovery.”</p> <p>Michael Kelly, Founder and Creatvve Director at Salon HER believes there is room for industry professionals to improve conversation and bolster skills for listening, empathising and creating a safe environment for clients trying to navigate cancer diagnosis and treatment.</p> <p>“I think language and the wholistic therapy side of the conversation could definitely improve. Not everyone has the resources to be able to hold space for another human in a very vulnerable stage of their life."</p> <p>"Style For Cancer is an obvious cause for me to be part of as I have lost family members I love to cancer, I’ve had family members recover from cancer, and I’ve supported clients who I care for deeply through some of their darkest days. It’s an initiative close to my heart.”</p> <p>Style For Cancer fundraising activities will take place in participating businesses Australia-wide during the month of August, however the Style Maker directory and registration in the initiative are available year-round.</p> <p>All funds <a href="https://donorbox.org/styleforcancerdonations" target="_blank" rel="noopener">raised</a> through the Style For Cancer initiative will directly support the Look Good Feel Better program, with each $100 raised allowing one participant to benefit from the program, free-of-charge.</p> <p><em>Image credits: Shutterstock </em></p> </div> </div> </div>

The ultimate treatment to transform your curls

<p>Every curly-haired girl knows the struggle of having to carry around multiple hair products to manage their curls. </p> <p>Anti-frizz serums, leave-in conditioners, curl cream and heat protection spray, are a few of the essentials that most curly hair girls can't live without, but what if there was a product that could do it all? </p> <p>Revlon's UniqOne Curls treatment is the perfect solution, and as someone who struggles with finding a curl treatment that doesn't leave my curls stringy or puffy, the treatment has become an essential part of my routine. </p> <p>The treatment boasts ten different benefits including:</p> <ol> <li>Deeply nourishes and repairs damaged curls</li> <li>Enhances long-lasting natural curl definition </li> <li>96H frizz control </li> <li>Elasticity and bounce </li> <li>Provides lightweight, clean hold </li> <li>Conditions and detangles</li> <li>Heat protection </li> <li>Boosts shine </li> <li>Helps prevent split ends </li> <li>Softness and manageability</li> </ol> <p>Yes, those are some big statements, but after my first use I could already see some of the benefits, especially as someone with fine, curly hair. </p> <p>I found that my hair was less frizzy and puffy and my curls were a lot more defined, even a few days after I initially applied it. I also loved the slight sweet and fruity scent that wasn't too overpowering. </p> <p>My hair was also easier to manage and style as it wasn't as tangled and despite the gel-like texture of the product, it didn't weigh down my fine hair or leave it feeling greasy. </p> <p>I found that the best way to use the product is to use it on damp hair. </p> <p>I like to pump the product onto the palm of my hand (approx. 5-12 times depending on the thickness and length of your hair) and then rubbing it in my hands, before applying it onto my hair on layered sections to ensure even distribution. </p> <p>I then detangle my hair with a wide tooth comb before scrunching my hair with my hands to ensure even curl clumps. </p> <p>I normally blow dry my hair, but it you have extra time on your hands, you can leave it to air dry. </p> <p>The product retails for $24.95 at <a href="https://www.ozhairandbeauty.com/products/revlon-professional-uniq-one-all-in-one-curls-treatment-230ml?currency=AUD&variant=40267971428424" target="_blank" rel="noopener">Oz Hair and Beauty</a> </p> <p><em>Images: Supplied</em></p>

"A bit grim": Sam Neill shares cancer update

<p>Actor Sam Neill has shared a heartbreaking update on his cancer journey, which he has said he will eventually succumb to. </p> <p>Last year, the 76-year-old revealed that he was battling rare blood cancer, angioimmunoblastic T-cell lymphoma.</p> <p>After undergoing chemotherapy that failed to work, Neill's doctor switched him to an anti-cancer drug which has put him in remission for more than 12 months. </p> <p>The treatment requires him to have infusions every two weeks, and while his condition is currently stable, the drug will eventually stop working. </p> <p>Speaking candidly to the <em>Herald Sun</em> about his condition, he said while he is maintaining a positive outlook, the gruelling treatment is impacting the way he lives his life.</p> <p>“It’s just meant that every second week it was a case of forget about the weekend because that would be a bit grim,” he explained of his treatment schedule. “But other than that, it’s great to be alive and working and in beautiful places, like York.”</p> <p>Last year, Sam insisted while he wasn’t afraid of death after battling the disease, he “would be annoyed” because he still has plenty he wants to achieve.</p> <p>“I’m prepared for that,” Neill said at the time, adding that while dying would be “annoying” he’s not “remotely afraid” of it.</p> <p>“The last thing I want is for people to obsess about the cancer thing because I’m not really interested in cancer," he added. "I’m not really interested in anything other than living.” </p> <p><em>Image credits: Matt Baron/BEI/Shutterstock Editorial </em></p> <p> </p>

Caring

Taking too many medications can pose health risks. Here’s how to avoid them

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/caroline-sirois-1524891">Caroline Sirois</a>, <a href="https://theconversation.com/institutions/universite-laval-1407">Université Laval</a></em></p> <p>When we see an older family member handling a bulky box of medications sorted by day of the week, we might stop and wonder, is it too much? How do all those pills interact?</p> <p>The fact is, as we get older we are more likely to develop different chronic illnesses that require us to take several different medications. This is known as polypharmacy. The concept applies to people taking five or more medications, but there are all sorts of <a href="https://doi.org/10.3390/pharmacy7030126">definitions with different thresholds</a> (for example, four, 10 or 15 medicines).</p> <p>I’m a pharmacist and pharmacoepidemiologist interested in polypharmacy and its impact on the population. The research I carry out with my team at the Faculty of Pharmacy at Université Laval focuses on the appropriate use of medication by older family members. We have published this <a href="https://doi.org/10.1093/ageing/afac244">study</a> on the perceptions of older adults, family carers and clinicians on the use of medication among persons over 65.</p> <h2>Polypharmacy among older adults</h2> <p>Polypharmacy is very common among older adults. In 2021, a quarter of persons over 65 in Canada were prescribed <a href="https://www.cihi.ca/en/drug-use-among-seniors-in-canada">more than ten different classes of medication</a>. In Québec, persons over 65 used an average of <a href="https://www.inspq.qc.ca/sites/default/files/publications/2679_portrait_polypharmacie_aines_quebecois.pdf">8.7 different drugs in 2016</a>, the latest year available for statistics.</p> <p>Is it a good idea to take so many drugs?</p> <p>According to <a href="https://journals.sagepub.com/doi/10.1177/07334648211069553">our study</a>, the vast majority of seniors and family caregivers would be willing to stop taking one or more medications if the doctor said it was possible, even though most are satisfied with their treatments, <a href="https://doi.org/10.1093/ageing/afac244">have confidence in their doctors</a> and feel that their doctors are taking care of them to the best of their ability.</p> <p>In the majority of cases, medicine prescribers are helping the person they are treating. Medications have a positive impact on health and are essential in many cases. But while the treatment of individual illnesses is often adequate, the whole package can sometimes become problematic.</p> <h2>The risks of polypharmacy: 5 points to consider</h2> <p>When we evaluate cases of polypharmacy, we find that the quality of treatment is often compromised when many medications are being taken.</p> <ol> <li> <p>Drug interactions: polypharmacy increases the risk of drugs interacting, which can lead to undesirable effects or reduce the effectiveness of treatments.</p> </li> <li> <p>A drug that has a positive effect on one illness may have a negative effect on another: what should you do if someone has both illnesses?</p> </li> <li> <p>The greater the number of drugs taken, the greater the risk of undesirable effects: for adults over 65, for example, there is an increased risk of confusion or falls, which have significant consequences.</p> </li> <li> <p>The more medications a person takes, the more likely they are to take a <a href="https://www.doi.org/10.1093/fampra/cmz060">potentially inappropriate medication</a>. For seniors, these drugs generally carry more risks than benefits. For example, benzodiazepines, medicine for anxiety or sleep, are the <a href="https://www.inspq.qc.ca/sites/default/files/publications/2575_utilisation_medicaments_potentiellement_inappropries_aines.pdf">most frequently used class</a> of medications. We want to reduce their use as much as possible <a href="https://www.canada.ca/en/health-canada/services/substance-use/controlled-illegal-drugs/benzodiazepines.html">to avoid negative impacts</a> such as confusion and increased risk of falls and car accidents, not to mention the risk of dependence and death.</p> </li> <li> <p>Finally, polypharmacy is associated with various adverse health effects, such as an <a href="https://www.doi.org/10.1007/s41999-021-00479-3">increase in frailty, hospital admissions and emergency room visits</a>. However, studies conducted to date have not always succeeded in isolating the effects specific to polypharmacy. As polypharmacy is more common among people with multiple illnesses, these illnesses may also contribute to the observed risks.</p> </li> </ol> <p>Polypharmacy is also a combination of medicines. There are almost as many as there are people. The risks of these different combinations can vary. For example, the risks associated with a combination of five potentially inappropriate drugs would certainly be different from those associated with blood pressure medication and vitamin supplements.</p> <p>Polypharmacy is therefore complex. <a href="https://doi.org/10.1186/s12911-021-01583-x">Our studies attempt to use artificial intelligence</a> to manage this complexity and identify combinations associated with negative impacts. There is still a lot to learn about polypharmacy and its impact on health.</p> <h2>3 tips to avoid the risks associated with polypharmacy</h2> <p>What can we do as a patient, or as a caregiver?</p> <ol> <li> <p>Ask questions: when you or someone close to you is prescribed a new treatment, be curious. What are the benefits of the medication? What are the possible side effects? Does this fit in with my treatment goals and values? How long should this treatment last? Are there any circumstances in which discontinuing it should be considered ?</p> </li> <li> <p>Keep your medicines up to date: make sure they are all still useful. Are there still any benefits to taking them? Are there any side effects? Are there any drug interactions? Would another treatment be better? Should the dose be reduced?</p> </li> <li> <p>Think about de-prescribing: this is an increasingly common clinical practice that involves stopping or reducing the dose of an inappropriate drug after consulting a health-care professional. It is a shared decision-making process that involves the patient, their family and health-care professionals. The <a href="https://www.deprescribingnetwork.ca">Canadian Medication Appropriateness and Deprescribing Network</a> is a world leader in this practice. It has compiled a number of tools for patients and clinicians. You can find them on their website and subscribe to the newsletter.</p> </li> </ol> <h2>Benefits should outweigh the risks</h2> <p>Medications are very useful for staying healthy. It’s not uncommon for us to have to take more medications as we age, but this shouldn’t be seen as a foregone conclusion.</p> <p>Every medication we take must have direct or future benefits that outweigh the risks associated with them. As with many other issues, when it comes to polypharmacy, the saying, “everything in moderation,” frequently applies.<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/230612/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/caroline-sirois-1524891">Caroline Sirois</a>, Professor in Pharmacy, <a href="https://theconversation.com/institutions/universite-laval-1407">Université Laval</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Body

Exercise, therapy and diet can all improve life during cancer treatment and boost survival. Here’s how

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/rob-newton-12124">Rob Newton</a>, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a></em></p> <p>With so many high-profile people <a href="https://www.theguardian.com/uk-news/2024/mar/23/cancer-charities-princess-of-wales-speaking-about-diagnosis">diagnosed with cancer</a> we are confronted with the stark reality the disease can strike any of us at any time. There are also reports certain cancers are <a href="https://www.cancer.org/research/acs-research-news/facts-and-figures-2024.html">increasing among younger people</a> in their 30s and 40s.</p> <p>On the positive side, medical treatments for cancer are advancing very rapidly. Survival rates are <a href="https://acsjournals.onlinelibrary.wiley.com/doi/10.3322/caac.21763">improving greatly</a> and some cancers are now being managed more as <a href="https://www.cancer.org/cancer/survivorship/long-term-health-concerns/cancer-as-a-chronic-illness.html">long-term chronic diseases</a> rather than illnesses that will rapidly claim a patient’s life.</p> <p>The <a href="https://www.cancer.org/cancer/managing-cancer/treatment-types.html">mainstays of cancer treatment</a> remain surgery, chemotherapy, radiation therapy, immunotherapy, targeted therapy and hormone therapy. But there are other treatments and strategies – “adjunct” or supportive cancer care – that can have a powerful impact on a patient’s quality of life, survival and experience during cancer treatment.</p> <h2>Keep moving if you can</h2> <p>Physical exercise is now recognised as a <a href="https://www.exerciseismedicine.org/">medicine</a>. It can be tailored to the patient and their health issues to stimulate the body and build an internal environment where <a href="https://wchh.onlinelibrary.wiley.com/doi/full/10.1002/tre.884">cancer is less likely to flourish</a>. It does this in a number of ways.</p> <p>Exercise provides a strong stimulus to our immune system, increasing the number of cancer-fighting immune cells in our blood circulation and infusing these into the tumour tissue <a href="https://jitc.bmj.com/content/9/7/e001872">to identify and kill cancer cells</a>.</p> <p>Our skeletal muscles (those attached to bone for movement) release signalling molecules called <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7288608/">myokines</a>. The larger the muscle mass, the more myokines are released – even when a person is at rest. However, during and immediately after bouts of exercise, a further surge of myokines is secreted into the bloodstream. Myokines attach to immune cells, stimulating them to be better “hunter-killers”. Myokines also signal directly to cancer cells <a href="https://www.sciencedirect.com/science/article/pii/S2095254623001175">slowing their growth and causing cell death</a>.</p> <p>Exercise can also greatly <a href="https://wchh.onlinelibrary.wiley.com/doi/full/10.1002/tre.884">reduce the side effects of cancer treatment</a> such as fatigue, muscle and bone loss, and fat gain. And it reduces the risk of <a href="https://doi.org/10.2337/diacare.27.7.1812">developing other chronic diseases</a> such as heart disease and type 2 diabetes. Exercise can maintain or improve quality of life and mental health <a href="https://www.hindawi.com/journals/tbj/2022/9921575/">for patients with cancer</a>.</p> <p>Emerging research evidence indicates exercise might increase the effectiveness of mainstream treatments such as <a href="https://aacrjournals.org/cancerres/article/81/19/4889/670308/Effects-of-Exercise-on-Cancer-Treatment-Efficacy-A">chemotherapy</a> and <a href="https://www.nature.com/articles/s41391-020-0245-z">radiation therapy</a>. Exercise is certainly essential for preparing the patient for any surgery to increase cardio-respiratory fitness, reduce systemic inflammation, and increase muscle mass, strength and physical function, and then <a href="https://www.jsams.org/article/S1440-2440(18)31270-2/fulltext">rehabilitating them after surgery</a>.</p> <p>These mechanisms explain why cancer patients who are physically active have much <a href="https://journals.lww.com/acsm-msse/fulltext/2019/06000/physical_activity_in_cancer_prevention_and.20.aspx">better survival outcomes</a> with the relative risk of death from cancer <a href="https://journals.lww.com/acsm-msse/fulltext/2019/06000/physical_activity_in_cancer_prevention_and.20.aspx">reduced by as much as 40–50%</a>.</p> <h2>Mental health helps</h2> <p>The second “tool” which has a major role in cancer management is <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6016045/">psycho-oncology</a>. It involves the psychological, social, behavioural and emotional aspects of cancer for not only the patient but also their carers and family. The aim is to maintain or improve quality of life and mental health aspects such as emotional distress, anxiety, depression, sexual health, coping strategies, personal identity and relationships.</p> <p>Supporting quality of life and happiness is important on their own, but these barometers <a href="https://www.frontiersin.org/journals/psychology/articles/10.3389/fpsyg.2024.1349880/full">can also impact</a> a patient’s physical health, response to exercise medicine, resilience to disease and to treatments.</p> <p>If a patient is highly distressed or anxious, their body can enter a flight or fight response. This creates an internal environment that is actually supportive of cancer progression <a href="https://www.cancer.gov/about-cancer/coping/feelings/stress-fact-sheet">through hormonal and inflammatory mechanisms</a>. So it’s essential their mental health is supported.</p> <h2>Putting the good things in: diet</h2> <p>A third therapy in the supportive cancer care toolbox is diet. A healthy diet <a href="https://www.cancer.org/cancer/survivorship/coping/nutrition/benefits.html">can support the body</a> to fight cancer and help it tolerate and recover from medical or surgical treatments.</p> <p>Inflammation provides a more fertile environment <a href="https://www.cancer.gov/news-events/cancer-currents-blog/2022/reducing-inflammation-to-treat-cancer">for cancer cells</a>. If a patient is overweight with excessive fat tissue then a diet to reduce fat which is also anti-inflammatory can be very helpful. This <a href="https://www.frontiersin.org/articles/10.3389/fnut.2021.709435/full">generally means</a> avoiding processed foods and eating predominantly fresh food, locally sourced and mostly plant based.</p> <p>Muscle loss is <a href="https://onlinelibrary.wiley.com/doi/10.1002/rco2.56">a side effect of all cancer treatments</a>. Resistance training exercise can help but people may need protein supplements or diet changes to make sure they get enough protein to build muscle. Older age and cancer treatments may reduce both the intake of protein and compromise absorption so <a href="https://www.sciencedirect.com/science/article/pii/S0261561421005422">supplementation may be indicated</a>.</p> <p>Depending on the cancer and treatment, some patients may require highly specialised diet therapy. Some cancers such as pancreatic, stomach, esophageal, and lung cancer can cause rapid and uncontrolled drops in body weight. This is called <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8233663/">cachexia and needs careful management</a>.</p> <p>Other cancers and treatments such as hormone therapy can cause rapid weight gain. This also needs careful monitoring and guidance so that, when a patient is clear of cancer, they are not left with higher risks of other health problems such as cardiovascular disease and metabolic syndrome (a cluster of conditions that boost your risk of heart disease, stroke and type 2 diabetes).</p> <h2>Working as a team</h2> <p>These are three of the most powerful tools in the supportive care toolbox for people with cancer.

Doctor beats cancer using his own treatment

<p>Australian doctor Richard Scolyer has been declared cancer free, thanks to a first-of-its-kind treatment he helped to develop.</p> <p>The 56-year-old professor, who has been recognised around for the world for his pioneering melanoma research, was diagnosed with aglioblastoma, a terminal kind of brain tumour, after suffering a seizure last June.</p> <p>After receiving his devastating diagnosis, the doctor agreed to be a "guinea pig" to undergo a world-first cancer treatment that he had a hand in developing. </p> <p>Now the world-leading pathologist and Australian of the Year has given a remarkable update, stating he is cancer free.</p> <p>“I had brain #MRI scan last Thursday looking for recurrent #glioblastoma (&/or treatment complications). I found out yesterday that there is still no sign of recurrence. I couldn’t be happier!!!!!” the professor shared on X, formerly known as Twitter.</p> <p>Before Dr Scolyer was diagnosed with cancer, he was fit and active, and had been hiking mountains in Poland with his wife.</p> <p>“I felt normal. I didn’t have any symptoms at all,” he told <em>A Current Affair</em> earlier this year.</p> <p>Just days after, he suffered a devastating seizure, and when he returned to Australia, underwent a series of tests which resulted in a diagnosis with glioblastoma – an aggressive and terminal form of brain cancer that would give him a average of 14 months to live. </p> <p>Teaming up with his friend and medical oncologist Georgina Long, Scolyer decided to undergo the new treatment, which came with a long list of risks. </p> <p>“No one knew what it was going to do, people were nervous because it could actually cause my life to end more quickly. But when you’re faced with certain death, it’s a no-brainer for me,” said Professor Scolyer, who also hoped the treatment would make a difference for other cancer patients.</p> <p>Dr Scolyer also underwent surgery to remove as much of his tumour as possible, and in April, he updated his social media followers to share that10 months after his diagnosis, his tumour had not returned. </p> <p>Speaking to ABC’s <em>Australian Story</em> at the time, Professor Scolyer said he was “blown away” by the results.</p> <p>“This is not what I expected. The average time to recurrence for the nasty type of brain cancer I’ve got is six months. So, to be out this far is amazing,” he said. </p> <p><em>Image credits: Instagram</em></p>

8 mistakes that make your hair thin

<p>Despite how many products you put load it up with, hair thins with age and there is scarcely anything that you can do to completely fight nature. What you can do is go into prevention mode as early as possible. There are many simple things that we do to our hair daily that is actually causing it a lot of stress and in many cases causing it to thin.</p> <p>So rather than a trip to the hairdresser every other week or falling for flashy and expensive products on cheap advertisements, follow these 8 simple tips to avoid damaging your hair and losing what you have.</p> <p><strong>1. Hot showers</strong></p> <p>We all know that hot water can dehydrate our skin, but did you know the same rule applies to your hair? Ryan Welter, MD, a Boston-based hair transplant surgeon explains; “Not only are you washing your hair’s protecting oils down the drain, but the heat throws your scalps pores into overdrive to keep up with oil production, which can damage the root and lead to additional shedding.”</p> <p><strong>2. Using too many heat tools</strong></p> <p>Ironic, isn’t it? All that that drying and curling we do to make our hair look fabulous is actually doing it the most damage. Not everyone is a wash-and-wear kind of person, though, so if you really can’t part with your heated tools, make sure you prep your strands with a heat protection spray. Also, they may be more expensive but ceramic plated tools are ten times better for your hair. The ceramic plate has a uniform heating system that makes it impossible for it to overheat and cause damage to the hair from burning. Additionally, you’ll get a better aesthetic result.</p> <p><strong>3. Crash dieting</strong></p> <p>Your diet affects everything, so it’s no surprise it effects your hair. Under eating forces, the body to direct the little energy it has to perform essential functions –like helping your heart pump blood-so generating new hair falls by the wayside. The good news is that you can eat certain foods for positive hair health. Lean protein like fish, chicken, lentil and beans all promote growth. Hair is primarily made of protein so it will make or break your hair. You should aim for about 46 grams per day.</p> <p><strong>4. Styling when wet</strong></p> <p>Our strands are never more fragile, and prone to breakage, than when they’re saturated with H20 – this is because the protective cuticle is slightly raised. Brushing or combing locks in the shower, then following with aggressive towel-drying and prompt styling is a recipe for swift breakages. To avoid this, let your hair dry as naturally as possible when you get out of the shower and wait patiently before styling.</p> <p><strong>5. Let’s talk about the colour</strong></p> <p>If your hair is dyed, and especially if it’s bleached, you will be more prone to breakage. However, there are many ways to avoid this. If you can’t be bothered fussing with various different treatments, simply leave your conditioner on for a few minutes rather than washing straight out. This will act like a hair treatment or mask without the hefty price tag. Alternatively, Moroccan oil is naturally high in fatty acids and vitamin E, making it a good treatment for damaged hair. Use sparingly on the ends, it only takes a few minutes to apply.</p> <p><strong>6. Opting for tight hairstyles</strong></p> <p>If you wear your hair back in a tight hairstyle, like a ponytail or bun, chances are it’s contributing to your thinning hair. Pulling on the hair follicles too tightly puts tension on them, damaging them and creating scars that destroy them permanently. This can lead to alopecia, a condition that permanently weakens the follicle and makes it impossible for hair to grow again. </p> <p><strong>7. Over-shampooing</strong></p> <p>The purpose of shampooing your hair is to cleanse the hair and scalp of oil and product build up. However, there is actually such thing as over-shampooing. This can wash away your hairs natural moisture that helps your hair look healthy and dries it out. This is especially true if you’re using a shampoo that’s more tropical scented foam than nutrition for your hair. So how much should you wash it? Unfortunately, there’s no specific algorithm. See what works best for you, stick to it, and always be gentle.</p> <p><strong>8. Using the wrong brush</strong></p> <p>Something as simple as using the wrong hairbrush could be doing you a world of damage. Unfortunately, the thinner your hair, the more damage brushing in general will do. Stick to coming and wide bristle brushes as to not aggravate delicate hair cells. For slick, slightly damp hair, natural-bristle brushes are best and for those who can get away with it, stick to a comb and nothing but the comb. Just be sure to check the teeth for seams or roughness.</p> <p>Finally, always go by the golden rule; if something is going to harm your skin, it’s going to harm your hair. </p> <p><em>Image credits: Shutterstock</em></p>
