5 questions to ask before becoming a carer

<p>Thinking about becoming a caregiver? Deciding to step up and provide care for a loved one is a huge responsibility. Make sure you’re prepared and ask these five vital questions first.</p> <p><strong>Do I need to hire help?</strong></p> <p>Just because you’re taking on caregiving duties doesn’t mean you have to be super human. It’s perfectly okay to ask for help, whether it’s in the form of a cleaner or someone to take on tasks that you would prefer to outsource. According to Health.com, 40 per cent of caregivers say dealing with incontinence is one of their most difficult task, while 30 per cent say helping relatives bathe is hard as well.</p> <p><strong>What is my Plan B?</strong></p> <p>If something should happen to you and your schedule or demands change, it’s important to discuss a back-up plan. As the primary carer, a lot of responsibility will rest on you so make sure you have a Plan B before you need one.</p> <p><strong>Should I be compensated?</strong></p> <p>A survey found that 60 per cent of careers adjust their work schedule to look after others, which means either cutting back hours or taking a leave of absence. While you might not want to accept money to care for loved ones, it’s a good idea to have an open discussion with close friends and family about how the responsibilities might impact your life and earning capacity, so that all parties agree on a fair solution.</p> <p><strong>What is Power of Attorney?</strong></p> <p>If you are looking after someone with memory loss, you may need to look into a legal document called power of attorney. Talk to family about who should have this responsibilities, and how you will navigate legal issues that could arise.</p> <p><strong>Who is my support group?</strong></p> <p>Roughly one in three carers don’t receive any help. Having a strong support network of people you can turn to, even just for a chat, can make a huge difference. You might be surprised by how many people you know are also caregivers.</p> <p><em>Image credits: Getty Images </em></p>

7 things you need to know about fear

<p>Fear is an emotion that can be debilitating and unsettling. But it is a natural part of life and we are hardwired to experience it.</p> <p><strong>1. Fear can protect you</strong></p> <p>Experiencing fear elicits responses from your brain to your limbs. It is the body’s natural way of protecting itself. For our ancestors the fear was often more physical – such as being chased by a lion. Modern fear can range from physical danger (such as a spider or an intruder) or even from perceived danger (such as the worry that something will happen to our partner or child). Feeling fear doesn’t make you a weak person. In fact, not feeling any fear could mean that there are neurological issues present.</p> <p><strong>2. There are many levels of fear</strong></p> <p>Not everything that we fear is intense and paralysing. It can range from low levels of fear (such as worry about being robbed), to medium levels of fear (say if a loved one is in hospital) to high levels of fear (you are being chased by an attacker). Fear can also become stronger when we hear about events such as a terrorist attack or a natural disaster. It all relates back to how much the scary event will impact our lives.</p> <p><strong>3. Fear is not just instinctive</strong></p> <p>We become fearful due to three main factors: instinct, learning, and teaching. An example of instinctual fear is pain – we learn to be fearful of things that hurt us. Learned fear comes from being exposed to unpleasant or uncomfortable things and wanting to avoid them in the future. For instance, having a relative die in a car crash could make you fearful of driving in the future. Other fears are taught to us by our family, friends and even society. For example, some religions teach us to be fearful of other religions or customs.</p> <p><strong>4. Fear can arise without a real threat of danger</strong></p> <p>Fear can also be imagined, so it can be felt even when there is no danger present. If we feel this all the time it can lead to anxiety and depression. It’s important to think about whether the thing you are fearful of is real or likely to happen before you give it too much airtime.</p> <p><strong>5. Fear produces fear</strong></p> <p>If you are already in a state of fear, your response to more fear is heightened. For instance if you are watching a scary movie, a small noise from the next room could make you jump and scream. Your senses are on red alert, primed to act if the need arises.</p> <p><strong>6. Fear leads to action</strong></p> <p>Depending on the individual and the level of fear they are experiencing, there tend to be four main types of action as a result of fear: freeze, </p> <p>fight, flight, or fright. </p> <p>When you freeze it means you don’t move while you decide what to do (for instance you see a snake in your garden). From there you choose either fight (grab a shovel) or flight mode (walk away). If the fear is too much you might experience fright, where you do nothing and take no action (stand there screaming or worrying).</p> <p><strong>7. Real threats can lead to heroic actions</strong></p> <p>Imagined threats can cause us to live in a permanent state of fear and stress. But often we will do nothing about it (for instance being worried about sharks attacking us in the ocean). Compare this to the threat from a real and identifiable source, which will make you spring into action almost immediately. Often we don’t even make the decision to act, it just happens automatically (such as moving a child out of the way of an approaching car). </p> <p><em>Image credits: Getty Images</em> </p>

How much time should you spend sitting versus standing? New research reveals the perfect mix for optimal health

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/christian-brakenridge-1295221">Christian Brakenridge</a>, <a href="https://theconversation.com/institutions/baker-heart-and-diabetes-institute-974">Baker Heart and Diabetes Institute</a></em></p> <p>People have a pretty intuitive sense of what is healthy – standing is better than sitting, exercise is great for overall health and getting <a href="https://theconversation.com/could-not-getting-enough-sleep-increase-your-risk-of-type-2-diabetes-225179">good sleep is imperative</a>.</p> <p>However, if exercise in the evening may disrupt our sleep, or make us feel the need to be more sedentary to recover, a key question emerges – what is the best way to balance our 24 hours to optimise our health?</p> <p><a href="https://link.springer.com/article/10.1007/s00125-024-06145-0">Our research</a> attempted to answer this for risk factors for heart disease, stroke and diabetes. We found the optimal amount of sleep was 8.3 hours, while for light activity and moderate to vigorous activity, it was best to get 2.2 hours each.</p> <p><iframe id="dw4bx" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/dw4bx/" width="100%" height="400px" frameborder="0"></iframe></p> <h2>Finding the right balance</h2> <p>Current health guidelines recommend you stick to a <a href="https://www.health.gov.au/topics/physical-activity-and-exercise/physical-activity-and-exercise-guidelines-for-all-australians/for-adults-18-to-64-years">sensible regime</a> of moderate-to vigorous-intensity physical activity 2.5–5 hours per week.</p> <p>However <a href="https://doi.org/10.1016/j.jacc.2019.02.031">mounting evidence</a> now <a href="https://doi.org/10.2337/dc14-2073">suggests</a> how you spend your day can have meaningful ramifications for your health. In addition to moderate-to vigorous-intensity physical activity, this means the time you spend sitting, standing, doing light physical activity (such as walking around your house or office) and sleeping.</p> <p>Our research looked at more than 2,000 adults who wore body sensors that could interpret their physical behaviours, for seven days. This gave us a sense of how they spent their average 24 hours.</p> <p>At the start of the study participants had their waist circumference, blood sugar and insulin sensitivity measured. The body sensor and assessment data was matched and analysed then tested against health risk markers — such as a heart disease and stroke risk score — to create a model.</p> <p>Using this model, we fed through thousands of permutations of 24 hours and found the ones with the estimated lowest associations with heart disease risk and blood-glucose levels. This created many optimal mixes of sitting, standing, light and moderate intensity activity.</p> <p>When we looked at waist circumference, blood sugar, insulin sensitivity and a heart disease and stroke risk score, we noted differing optimal time zones. Where those zones mutually overlapped was ascribed the optimal zone for heart disease and diabetes risk.</p> <h2>You’re doing more physical activity than you think</h2> <p>We found light-intensity physical activity (defined as walking less than 100 steps per minute) – such as walking to the water cooler, the bathroom, or strolling casually with friends – had strong associations with glucose control, and especially in people with type 2 diabetes. This light-intensity physical activity is likely accumulated intermittently throughout the day rather than being a purposeful bout of light exercise.</p> <p>Our experimental evidence shows that <a href="https://diabetesjournals.org/care/article/39/6/964/29532/Benefits-for-Type-2-Diabetes-of-Interrupting">interrupting our sitting</a> regularly with light-physical activity (such as taking a 3–5 minute walk every hour) can improve our metabolism, especially so after lunch.</p> <p>While the moderate-to-vigorous physical activity time might seem a quite high, at more than 2 hours a day, we defined it as more than 100 steps per minute. This equates to a brisk walk.</p> <p>It should be noted that these findings are preliminary. This is the first study of heart disease and diabetes risk and the “optimal” 24 hours, and the results will need further confirmation with longer prospective studies.</p> <p>The data is also cross-sectional. This means that the estimates of time use are correlated with the disease risk factors, meaning it’s unclear whether how participants spent their time influences their risk factors or whether those risk factors influence how someone spends their time.</p> <h2>Australia’s adult physical activity guidelines need updating</h2> <p>Australia’s <a href="https://www.health.gov.au/topics/physical-activity-and-exercise/physical-activity-and-exercise-guidelines-for-all-australians/for-adults-18-to-64-years">physical activity guidelines</a> currently only recommend exercise intensity and time. A <a href="https://www.uow.edu.au/media/2023/why-adults-need-to-move-more-stop-sitting-and-sleep-better-.php">new set of guidelines</a> are being developed to incorporate 24-hour movement. Soon Australians will be able to use these guidelines to examine their 24 hours and understand where they can make improvements.</p> <p>While our new research can inform the upcoming guidelines, we should keep in mind that the recommendations are like a north star: something to head towards to improve your health. In principle this means reducing sitting time where possible, increasing standing and light-intensity physical activity, increasing more vigorous intensity physical activity, and aiming for a healthy sleep of 7.5–9 hours per night.</p> <p>Beneficial changes could come in the form of reducing screen time in the evening or opting for an active commute over driving commute, or prioritising an earlier bed time over watching television in the evening.</p> <p>It’s also important to acknowledge these are recommendations for an able adult. We all have different considerations, and above all, movement should be fun.<!-- Below is The Conversation's page counter tag.

How extreme dieting can affect bone health

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/adam-taylor-283950">Adam Taylor</a>, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a></em></p> <p>In a recent Instagram post, the actor Jameela Jamil revealed she has poor bone density, despite only being in her 30s. Jamil blamed this finding on 20 years of dieting – urging her followers to be aware of the harms diet culture can do to your health.</p> <p>Bone density is important for many reasons, primarily because it acts as a reservoir for many of the important minerals our bones need to function well. Many factors can affect your bone density – and as Jamil has pointed out, diet is one component that has a significant effect on bone health.</p> <p>Bone is a living tissue. This means our skeleton <a href="https://www.sciencedirect.com/science/article/abs/pii/S1521690X08000869">grows and remodels itself</a> according to the stresses and strains it’s put under. Everything from fractures to exercise require our bones to change their shape or density. This is why a weightlifter’s skeleton is <a href="https://link.springer.com/article/10.1007/BF00298721">much denser</a> than a marathon runner’s.</p> <p>The biggest skeletal changes we experience happen in our younger years. But bones keep changing throughout our lives depending on how active we are, what our diet consists of, and if we’ve suffered an injury or disease.</p> <p>Bones are <a href="https://www.niams.nih.gov/health-topics/what-bone">made of proteins</a>, such as collagen, as well as minerals – largely calcium. This is a <a href="https://www.ncbi.nlm.nih.gov/books/NBK430714/">key mineral</a> for us, as it keeps our bones and teeth strong and helps repair and rebuild any injured bones.</p> <p>But other minerals and vitamins are also important. For example, vitamin D supports calcium, playing a key role in <a href="https://jamanetwork.com/journals/jamapediatrics/fullarticle/2761808">bone mineralisation</a>. This is where calcium <a href="https://www.ncbi.nlm.nih.gov/books/NBK279023/">combines with phosphate</a> in our bones to create the mineral crystal <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7264100/">hydroxyapatite</a>. This crystal is crucial to our bone mineral density (also known as “bone mass”), as it helps bones remodel and maintain their structural strength.</p> <p><a href="https://www.nhs.uk/conditions/dexa-scan/">Dexa scans</a> – the type of scan Jamil referred to in her post – can measure the density of these crystals in bones. The <a href="https://theros.org.uk/information-and-support/osteoporosis/scans-tests-and-results/bone-density-scan-dxa/">more hydroxyapatite crystals</a> detected, the healthier the bones are.</p> <figure class="align-center "><img src="https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=338&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=338&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=338&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=424&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=424&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=424&amp;fit=crop&amp;dpr=3 2262w" alt="The interior of bones, showing four depictions of bone density – from healthy to severe osteoporosis." /><figcaption><span class="caption">The more crystals detected, the better your bone density.</span> <span class="attribution"><a class="source" href="https://www.shutterstock.com/image-illustration/osteoporosis-4-stages-one-picture-3d-524364046">Crevis/ Shutterstock</a></span></figcaption></figure> <p>We hit peak bone mineral density in our <a href="https://pubmed.ncbi.nlm.nih.gov/35869910/">late teens and early 20s</a>, when our body has grown to full size and our metabolism is working its best. From here, it’s possible to maintain <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5684300/">stable bone mass</a> into your late 30s for women and early 40s for men, with the right diet and activity. But after this point, it begins to decline.</p> <h2>Bone density</h2> <p>We accrue calcium over many years. It initially comes from our mother, then later from our diet. Our body accrues calcium so it can adapt to times when calcium demand is greater than what we can get from our diet – such as during pregnancy, when the foetus needs calcium to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3355895/">build its own bones</a>.</p> <p>However, relying solely on this skeletal calcium reserve can’t be sustained for lengthy or repeated periods, because of how long it takes to be replenished. This is why diet is so important for bone density – and why a poor diet can cause extreme damage, especially when certain food groups or minerals are consistently left out.</p> <p>For instance, studies have shown consuming soft drinks, (<a href="https://pubmed.ncbi.nlm.nih.gov/17023723/">particularly cola</a>), more than four times a week is linked with <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7071508/">lower bone density</a> and increased fracture risk. This is true even after adjusting for many other variables that affect bone density.</p> <p>These carbonated and energy drinks contain <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2966367/">varying levels of vitamins</a> – often with none of the minerals, including calcium, that the body needs to function optimally. This causes the body to draw on its reserves if calcium isn’t being delivered elsewhere in the diet.</p> <p>Diets high in added sugar can also have a detrimental affect on the skeleton. Excess sugar causes inflammation and other physiological changes, such as <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9471313/">obesity</a>. Consuming high amounts of sugar is linked with <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2748414/">reduced calcium intake</a>, especially in children who substitute milk for sugary drinks. Excess sugar consumption also causes the body to <a href="https://jps.biomedcentral.com/articles/10.1007/s12576-016-0487-7">excrete excess calcium</a>, instead of reabsorbing it in the kidney as the body normally would.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/25491765/">Low- and high-fat diets</a> have also been associated with increased risk of <a href="https://www.nhs.uk/conditions/osteoporosis/">osteoporosis</a> (a condition that weakens bones) in women – though larger studies are needed to better understand the effects of removing whole food groups on bone health.</p> <p><a href="https://www.nhs.uk/mental-health/conditions/anorexia/overview/">Anorexia nervosa</a> also has a significant affect on <a href="https://pubmed.ncbi.nlm.nih.gov/30817009">bone density</a> – affecting a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6959847/">majority of people</a> with the condition.</p> <p>Low bone mineral density – especially in the spine – puts people with anorexia at <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6959847/">increased risk of fractures</a> because their bone thickness is reduced, increasing the likelihood of developing osteoporosis, which is associated with increased fractures.</p> <p>Anorexia in young adulthood is particularly challenging. This is the stage where the skeleton is building itself to reach peak <a href="https://pubmed.ncbi.nlm.nih.gov/15574617/">bone mass</a>, so it’s depositing calcium at a record pace. When diet is insufficient and the body already starts drawing on its mineral reserves, there’s a potential that the bone density or calcium reserves in the body will never be optimal – increasing fracture risk for the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6746661/">rest of that person’s life</a>.</p> <h2>Can bone health be fixed?</h2> <p>Optimal bone health starts in utero, but our prepubescent years are key to <a href="https://pubmed.ncbi.nlm.nih.gov/26884506/">setting our skeleton up</a> for later life. People who are behind the curve in early life may have difficulty achieving their peak, as poor bone mineral density can affect everything from our appetite to how efficient our gastrointestinal tract is at absorbing <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6971894/">important nutrients</a> (including calcium). Supplements have a limited effect because our body can only absorb a set amount of any <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8746734/">vitamin or mineral at a time</a>.</p> <p>While it’s possible to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5684300/">limit some of the decline</a> in bone density that naturally happens as we age, some of the choices we make – such as not consuming enough calcium – can accelerate the decline. Biological sex also has a significant impact on our bone health in old age – with post-menopausal women at greater risk of osteoporosis because they <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5643776/">produce less oestrogen</a>, which helps keep the cells that <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3424385">degrade bone</a> in check.<!-- Below is The Conversation's page counter tag.

King Charles returns to public duties for the first time since diagnosis

<p>King Charles has made his first official public appearance since being diagnosed with cancer in February. </p> <p>In a symbolic appearance on Tuesday morning, the royal visited the Macmillan Cancer Centre at the University College Hospital donning a navy pinstripe suit with a light blue shirt and a pink dinosaur tie.</p> <p>The monarch was joined by his wife, Queen Camilla, with the couple sporting huge smiles as they waved to the crowd outside of the London hospital. </p> <p>The royal couple met with clinicians, patients and families of patients during the visit, and when asked by one patient how his treatment was going, Charles replied: "I'm alright, thank you".</p> <p>In one photo Charles can be seen tenderly placing his hand on the arms of a patient as he spoke with them. </p> <p>One patient discussed her chemotherapy with Charles, who who told her: “I’ve got to have my treatment this afternoon as well,” according to the <em>Mirror</em>.</p> <p>He also shared his reaction to finding out about his diagnosis for the first time, telling one patient: “It’s always a bit of a shock, isn’t it, when they tell you?”</p> <p>The King's hospital visit comes just days after the Palace released a statement confirming that he was showing progress with his treatment and would be resuming official duties. </p> <p>“His Majesty The King will shortly return to public-facing duties after a period of treatment and recuperation following his recent cancer diagnosis,”  it read, before announcing the visit to the cancer centre. </p> <p>“This visit will be the first in a number of external engagements His Majesty will undertake in the weeks ahead.”</p> <p>Despite this, his upcoming summer schedule would not be a full one, with events like the King's Birthday parade, known as Trooping the Colour, and the Royal Ascot, being undertaken on a case-by-case basis. </p> <p>He also plans to host the Emperor and Empress of Japan in late June. </p> <p>“As the first anniversary of the Coronation approaches, Their Majesties remain deeply grateful for the many kindnesses and good wishes they have received from around the world throughout the joys and challenges of the past year,” the statement concluded. </p> <p><em>Image: Getty</em></p>

Christina Applegate details bout of Covid and Sapovirus amid MS battle

<p>Christina Applegate has detailed her latest health battle amid her multiple sclerosis (MS).</p> <p>Speaking on her <em>MesSy</em> podcast with co-host Jamie-Lynn Sigler, the actress revealed her rough experience after contracting Covid for the first time, which then turned into long Covid, and to make matters worse, she then contracted Sapovirus from contaminated food. </p> <p>Sapoviruses can cause acute gastroenteritis, and the actress candidly shared that she had been wearing diapers in recent weeks because of how often she has had to go to the bathroom. </p> <p>"I finally got the Covies.. someone real close to me dropped the ball and came home with the stuff and it spread all over the house," she began.</p> <p>"I had one day when I had a headache and chills and I thought I was making it through this."</p> <p>"It turned into long covid and it turned into a chest infection and then my heart was doing weird stuff, where it just speeds up... so I was like mother f--ker!"</p> <p>She then continued, saying that after contracting the virus she was "p---ing out of her a** for a few days".</p> <p>"I was so dizzy. I was so sick. I couldn't eat... Someone else's poop went into my mouth and I ate it."</p> <p>The actress recently revealed that she has 30 lesions on her brain from her MS,  a condition where the body's own immune system mistakenly attacks and damages the fatty material around the nerves, which can cause a range of symptoms. </p> <p>It is the most common acquired chronic neurological disease affecting young adults, according to MS Australia. </p> <p><em>Image: Getty</em></p>

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/andree-ann-baril-1494268">Andrée-Ann Baril</a>, <a href="https://theconversation.com/institutions/universite-de-montreal-1743">Université de Montréal</a> and <a href="https://theconversation.com/profiles/matthew-pase-1494296">Matthew Pase</a>, <a href="https://theconversation.com/institutions/monash-university-1065"><em>Monash University</em></a></em></p> <p>Dementia is a progressive loss of cognitive abilities, such as memory, that is significant enough to have an impact on a person’s daily activities.</p> <p>It can be caused by a number of different diseases, including <a href="https://alzheimer.ca/en/about-dementia/what-alzheimers-disease">Alzheimer’s</a>, which is the most common form. Dementia is caused by a loss of neurons over a long period of time. Since, by the time symptoms appear, many changes in the brain have already occurred, many scientists are focusing on studying the risk and protective factors for dementia.</p> <p>A risk factor, or conversely, a protective factor, is a condition or behaviour that increases or reduces the risk of developing a disease, but does not guarantee either outcome. Some risk factors for Alzheimer’s disease and dementia, such as age or genetics, are not modifiable, but there are several other factors we can influence, <a href="https://www.thelancet.com/article/S0140-6736(20)30367-6/fulltext">specifically lifestyle habits and their impact on our overall health</a>.</p> <p>These risk factors include depression, lack of physical activity, social isolation, high blood pressure, obesity, diabetes, excessive alcohol consumption and smoking, as well as poor sleep.</p> <p>We have been focusing our research on the question of sleep for over 10 years, particularly in the context of the <a href="https://www.nhlbi.nih.gov/science/framingham-heart-study-fhs">Framingham Heart Study</a>. In this large community-based cohort study, ongoing since the 1940s, the health of surviving participants has been monitored to the present day. As researchers in sleep medicine and epidemiology, we have expertise in researching the role of sleep and sleep disorders in cognitive and psychiatric brain aging.</p> <p>As part of our research, we monitored and analyzed the sleep of people aged 60 and over to see who did — or did not — develop dementia.</p> <h2>Sleep as a risk or protective factor against dementia</h2> <p>Sleep appears to play an essential role in a number of brain functions, such as memory. Good quality sleep <a href="https://jamanetwork.com/journals/jamaneurology/fullarticle/2793873">could therefore play a vital role in preventing dementia</a>.</p> <p>Sleep is important for maintaining <a href="https://www.science.org/doi/10.1126/science.1241224">good connections in the brain</a>. Recently, research has revealed that sleep seems to have a function similar to that of a garbage truck for the brain: <a href="https://doi.org/10.1016/j.mad.2023.111899">deep sleep could be crucial for eliminating metabolic waste from the brain</a>, including clearing certain proteins, such as those known to accumulate in the brains of people with Alzheimer’s disease.</p> <p>However, the links between deep sleep and dementia still have to be clarified.</p> <h2>What is deep sleep?</h2> <p>During a night’s sleep, we go through several <a href="http://ceams-carsm.ca/en/a-propos-du-sommeil/">sleep stages</a> that succeed one another and are repeated.</p> <p>NREM sleep (non-rapid eye movement sleep) is divided into light NREM sleep (NREM1 stage), NREM sleep (NREM2 stage) and deep NREM sleep, also called slow-wave sleep (NREM3 stage). The latter is associated with several restorative functions. Next, REM sleep (rapid eye movement sleep) is the stage generally associated with the most vivid dreams. An adult generally spends around 15 to 20 per cent of each night in deep sleep, if we add up all the periods of NREM3 sleep.</p> <p>Several sleep changes are common in adults, such as going to bed and waking up earlier, sleeping for shorter periods of time and less deeply, and waking up more frequently during the night.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=279&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=279&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=279&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=350&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=350&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=350&amp;fit=crop&amp;dpr=3 2262w" alt="" /></a><figcaption><span class="caption">Sleep stages, and the role of deep sleep for brain health.</span> <span class="attribution"><span class="source">(Andrée-Ann Baril)</span></span></figcaption></figure> <h2>Loss of deep sleep linked to dementia</h2> <p>Participants in the <a href="https://jamanetwork.com/journals/jamaneurology/fullarticle/2810957">Framingham Heart Study</a> were assessed using a sleep recording — known as polysomnography — on two occasions, approximately five years apart, in 1995-1998 and again in 2001-2003.</p> <p>Many people showed a reduction in their deep slow-wave sleep over the years, as is to be expected with aging. Conversely, the amount of deep sleep in some people remained stable or even increased.</p> <p>Our team of researchers from the Framingham Heart Study followed 346 participants aged 60 and over for a further 17 years to observe who developed dementia and who did not.</p> <p>Progressive loss of deep sleep over time was associated with an increased risk of dementia, whatever the cause, and particularly Alzheimer’s type dementia. These results were independent of many other risk factors for dementia.</p> <p>Although our results do not prove that loss of deep sleep causes dementia, they do suggest that it could be a risk factor in the elderly. Other aspects of sleep may also be important, such as its duration and quality.</p> <h2>Strategies to improve deep sleep</h2> <p>Knowing the impact of a lack of deep sleep on cognitive health, what strategies can be used to improve it?</p> <p>First and foremost, if you’re experiencing sleep problems, it’s worth talking to your doctor. Many sleep disorders are underdiagnosed and treatable, particularly through behavioural (i.e. non-medicinal) approaches.</p> <p>Adopting good sleep habits can help, such as going to bed and getting up at consistent times or avoiding bright or blue light in bed, like that of screens.</p> <p>You can also avoid caffeine, limit your alcohol intake, maintain a healthy weight, be physically active during the day, and sleep in a comfortable, dark and quiet environment.</p> <p>The role of deep sleep in preventing dementia remains to be explored and studied. Encouraging sleep with good lifestyle habits could have the potential to help us age in a healthier way.<!-- Below is The Conversation's page counter tag.

How tracking menopause symptoms can give women more control over their health

<p><a href="https://theconversation.com/profiles/deborah-lancastle-1452267">Deborah Lancastle</a>, <em><a href="https://theconversation.com/institutions/university-of-south-wales-1586">University of South Wales</a></em></p> <p>Menopause can cause more symptoms than hot flushes alone. And some of your symptoms and reactions might be due to the menopause, even if you are still having periods. Research shows that keeping track of those symptoms can help to alleviate them.</p> <p>People sometimes talk about the menopause as though it were a single event that happens when you are in your early 50s, which is <a href="https://www.mayoclinic.org/diseases-conditions/menopause/symptoms-causes/syc-20353397#:%7E:text=Menopause%20is%20the%20time%20that,is%20a%20natural%20biological%20process.">the average time</a> to have your last period. But the menopause generally stretches between the ages of 45 and 55. And some women will experience an earlier “medical” menopause because of surgery to remove the womb or ovaries.</p> <p>The menopause often happens at one of the busiest times of life. You might have teenagers at home or be supporting grown-up children, have elderly parents, be employed and have a great social life. If you feel exhausted, hot and bothered, irritable and can’t sleep well, you might be tempted to think that it is because you never get a minute’s peace. But that is why monitoring symptoms is important.</p> <p><a href="https://journals.lww.com/menopausejournal/Abstract/2023/03000/Symptom_monitoring_improves_physical_and_emotional.7.aspx">My team recently tested</a> the effects of tracking symptoms and emotions during the menopause. We asked women to rate 30 physical and 20 emotional symptoms of the menopause.</p> <p>The physical and psychological symptoms included poor concentration, problems with digesting food, stress and itchy skin, as well as the obvious symptoms like hot flushes and night sweats. Women tracked positive emotions like happiness and contentment, and negative emotions like feeling sad, isolated and angry.</p> <p>There were two groups of women in this study. One group recorded their symptoms and emotions every day for two weeks. The other group recorded their symptoms and emotions once at the beginning of the fortnight and once at the end.</p> <p>The results showed that the women who monitored their symptoms and emotions every day reported much lower negative emotions, physical symptoms and loneliness at the end of two weeks than at the beginning, compared to the other group.</p> <p>As well as this, although the loneliness scores of the group who monitored every day were lower than the other group, women in both groups said that being in the study and thinking about symptoms helped them feel less lonely. Simply knowing that other women were having similar experiences seemed to help.</p> <p>One participant said: “I feel more normal that other women are doing the same survey and are probably experiencing similar issues, especially the emotional and mental ones.”</p> <h2>Why does monitoring symptoms help?</h2> <p>One reason why tracking might help is that rating symptoms can help you notice changes and patterns in how you feel. This could encourage you to seek help.</p> <p>Another reason is that noticing changes in symptoms might help you link the change to what you have been doing. For example, looking at whether symptoms spike after eating certain foods or are better after exercise. This could mean that you change your behaviour in ways that improve your symptoms.</p> <p>Many menopause symptoms are known as “non-specific” symptoms. This is because they can also be symptoms of mental health, thyroid or heart problems. It is important not to think your symptoms are “just” the menopause. You should always speak to your doctor if you are worried about your health.</p> <p>Another good thing about monitoring symptoms is that you can take information about how often you experience symptoms and how bad they are to your GP appointment. This can help the doctor decide what might be the problem.</p> <p>Websites such as <a href="https://healthandher.com">Health and Her</a> and <a href="https://www.balance-menopause.com">Balance</a> offer symptom monitoring tools that can help you track what is happening to your physical and emotional health. There are several apps you can use on your phone, too. Or you might prefer to note symptoms and how bad they are in a notebook every day.<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/209004/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/deborah-lancastle-1452267">Deborah Lancastle</a>, Associate Professor of Psychology, <a href="https://theconversation.com/institutions/university-of-south-wales-1586">University of South Wales</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Good news: midlife health is about more than a waist measurement. Here’s why

<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>You’re not in your 20s or 30s anymore and you know regular health checks are important. So you go to your GP. During the appointment they measure your waist. They might also check your weight. Looking concerned, they recommend some lifestyle changes.</p> <p>GPs and health professionals commonly <a href="https://theconversation.com/the-body-mass-index-cant-tell-us-if-were-healthy-heres-what-we-should-use-instead-211190">measure waist circumference</a> as a vital sign for health. This is a better indicator than body mass index (BMI) of the amount of intra-abdominal fat. This is the really risky fat around and within the organs that can drive heart disease and metabolic disorders such as type 2 diabetes.</p> <p>Men are at greatly increased risk of health issues if their waist circumference is <a href="https://www.bmj.com/content/311/7017/1401">greater than 102 centimetres</a>. Women are considered to be at greater risk with a waist circumference of <a href="https://www.bmj.com/content/311/7017/1401">88 centimetres or more</a>. More than <a href="https://www.abs.gov.au/statistics/health/health-conditions-and-risks/waist-circumference-and-bmi/latest-release">two-thirds of Australian adults</a> have waist measurements that put them at an increased risk of disease. An even better indicator is waist circumference divided by height or <a href="https://www.baker.edu.au/news/in-the-media/waist-height-ratio#:%7E:text=According%20to%20research%2C%20a%20healthy,the%20highest%20risk%20of%20disease.">waist-to-height ratio</a>.</p> <p>But we know people (especially women) have a propensity to <a href="https://www.ajog.org/article/S0002-9378(19)30588-5/abstract">gain weight around their middle during midlife</a>, which can be very hard to control. Are they doomed to ill health? It turns out that, although such measurements are important, they are not the whole story when it comes to your risk of disease and death.</p> <h2>How much is too much?</h2> <p>Having a waist circumference to height ratio larger than 0.5 is associated with greater risk of chronic disease as well as premature death and this applies in adults of any age. A healthy waist-to-height ratio is between 0.4 to 0.49. A ratio of 0.6 or more <a href="https://www.baker.edu.au/news/in-the-media/waist-height-ratio#:%7E:text=According%20to%20research%2C%20a%20healthy,the%20highest%20risk%20of%20disease">places a person at the highest risk of disease</a>.</p> <p>Some experts recommend <a href="https://www.nature.com/articles/s41574-019-0310-7">waist circumference be routinely measured in patients during health appointments</a>. This can kick off a discussion about their risk of chronic diseases and how they might address this.</p> <p>Excessive body fat and the associated health problems manifest more strongly during midlife. A range of social, personal and physiological factors come together to make it more difficult to control waist circumference as we age. Metabolism tends to slow down mainly due to decreasing muscle mass because people do <a href="https://onlinelibrary.wiley.com/doi/10.1002/jcb.25077">less vigorous physical activity, in particular resistance exercise</a>.</p> <p>For women, hormone levels begin changing in mid-life and this also <a href="https://www.tandfonline.com/doi/full/10.3109/13697137.2012.707385">stimulates increased fat levels particularly around the abdomen</a>. At the same time, this life phase (often involving job responsibilities, parenting and caring for ageing parents) is when elevated stress can lead to <a href="https://journals.lww.com/psychosomaticmedicine/abstract/2000/09000/stress_and_body_shape__stress_induced_cortisol.5.aspx">increased cortisol which causes fat gain in the abdominal region</a>.</p> <p>Midlife can also bring poorer sleep patterns. These contribute to fat gain with <a href="https://journals.plos.org/plosmedicine/article?id=10.1371/journal.pmed.0010062">disruption to the hormones that control appetite</a>.</p> <p>Finally, your family history and genetics can <a href="https://journals.plos.org/plosgenetics/article?id=10.1371/journal.pgen.1002695">make you predisposed to gaining more abdominal fat</a>.</p> <h2>Why the waist?</h2> <p>This intra-abdominal or visceral fat is much more metabolically active (it has a greater impact on body organs and systems) than the fat under the skin (subcutaneous fat).</p> <p>Visceral fat surrounds and infiltrates major organs such as the liver, pancreas and intestines, releasing a variety of chemicals (hormones, inflammatory signals, and fatty acids). These affect inflammation, lipid metabolism, cholesterol levels and insulin resistance, <a href="https://academic.oup.com/eurheartjsupp/article/8/suppl_B/B4/461962">contributing to the development of chronic illnesses</a>.</p> <p>The issue is particularly evident <a href="https://www.ajog.org/article/S0002-9378(19)30588-5/abstract">during menopause</a>. In addition to the direct effects of hormone changes, <a href="https://www.sciencedirect.com/science/article/pii/S0960076013001118?via%3Dihub">declining levels of oestrogen change brain function, mood and motivation</a>. These psychological alterations can result in reduced physical activity and increased eating – often of comfort foods high in sugar and fat.</p> <p>But these outcomes are not inevitable. Diet, exercise and managing mental health can limit visceral fat gains in mid-life. And importantly, the waist circumference (and ratio to height) is just one measure of human health. There are so many other aspects of body composition, exercise and diet. These can have much larger influence on a person’s health.</p> <h2>Muscle matters</h2> <p>The quantity and quality of skeletal muscle (attached to bones to produce movement) a person has makes a <a href="https://www.nature.com/articles/nrendo.2012.49">big difference</a> to their heart, lung, metabolic, immune, neurological and mental health as well as their physical function.</p> <p>On current evidence, it is equally or more important for health and longevity to <a href="https://www.bmj.com/content/345/bmj.e7279">have</a> higher muscle mass and better cardiorespiratory (aerobic) fitness than waist circumference within the healthy range.</p> <p>So, if a person does have an excessive waist circumference, but they are also sedentary and have less muscle mass and aerobic fitness, then the recommendation would be to focus on an appropriate exercise program. The fitness deficits should be addressed as priority rather than worry about fat loss.</p> <p>Conversely, a person with low visceral fat levels is not necessarily fit and healthy and may have quite poor aerobic fitness, muscle mass, and strength. <a href="https://bjsm.bmj.com/content/45/6/504">The research evidence</a> is that these vital signs of health – how strong a person is, the quality of their diet and how well their heart, circulation and lungs are working – are more predictive of risk of disease and death than how thin or fat a person is.</p> <p>For example, a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5510687/">2017 Dutch study</a> followed overweight and obese people for 15 years and found people who were very physically active had no increased heart disease risk than “normal weight” participants.</p> <h2>Getting moving is important advice</h2> <p>Physical activity has many benefits. Exercise can counter a lot of the negative behavioural and physiological changes that are occurring during midlife including for people going through menopause.</p> <p>And regular exercise reduces the tendency to use food and drink to help manage what can be a <a href="https://journals.lww.com/acsm-msse/fulltext/2008/05000/physical_activity,_sedentary_index,_and_mental.7.aspx">quite difficult time in life</a>.</p> <p>Measuring your waist circumference and monitoring your weight remains important. If the measures exceed the values listed above, then it is certainly a good idea to make some changes. Exercise is effective for fat loss and in particular <a href="https://bjsm.bmj.com/content/57/16/1035">decreasing visceral fat</a> with greater effectiveness when <a href="https://bmcwomenshealth.biomedcentral.com/articles/10.1186/s12905-019-0864-5">combined with dietary restriction of energy intake</a>. Importantly, any fat loss program – whether through drugs, diet or surgery – is also a muscle loss program unless resistance exercise is part of the program. Talking about your overall health with a doctor is a great place to start.</p> <p><a href="https://www.essa.org.au/Public/Public/Searches/find-aep-withdistance.aspx">Accredited exercise physiologists</a> and <a href="https://member.dietitiansaustralia.org.au/Portal/Portal/Search-Directories/Find-a-Dietitian.aspx">accredited practising dietitians</a> are the most appropriate allied health professionals to assess your physical structure, fitness and diet and work with you to get a plan in place to improve your health, fitness and reduce your current and future health risks.<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/226019/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/rob-newton-12124"><em>Rob Newton</em></a><em>, Professor of Exercise Medicine, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Could not getting enough sleep increase your risk of type 2 diabetes?

<p><em><a href="https://theconversation.com/profiles/giuliana-murfet-1517219">Giuliana Murfet</a>, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a> and <a href="https://theconversation.com/profiles/shanshan-lin-1005236">ShanShan Lin</a>, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936"><em>University of Technology Sydney</em></a></em></p> <p>Not getting enough sleep is a common affliction in the modern age. If you don’t always get as many hours of shut-eye as you’d like, perhaps you were concerned by news of a <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2815684">recent study</a> that found people who sleep less than six hours a night are at higher risk of type 2 diabetes.</p> <p>So what can we make of these findings? It turns out the relationship between sleep and diabetes is complex.</p> <h2>The study</h2> <p>Researchers analysed data from the <a href="https://www.ukbiobank.ac.uk/">UK Biobank</a>, a large biomedical database which serves as a global resource for health and medical research. They looked at information from 247,867 adults, following their health outcomes for more than a decade.</p> <p>The researchers wanted to understand the associations between sleep duration and type 2 diabetes, and whether a healthy diet reduced the effects of short sleep on diabetes risk.</p> <p>As part of their involvement in the UK Biobank, participants had been asked roughly how much sleep they get in 24 hours. Seven to eight hours was the average and considered normal sleep. Short sleep duration was broken up into three categories: mild (six hours), moderate (five hours) and extreme (three to four hours). The researchers analysed sleep data alongside information about people’s diets.</p> <p>Some 3.2% of participants were diagnosed with type 2 diabetes during the follow-up period. Although healthy eating habits were associated with a lower overall risk of diabetes, when people ate healthily but slept less than six hours a day, their risk of type 2 diabetes increased compared to people in the normal sleep category.</p> <p>The researchers found sleep duration of five hours was linked with a 16% higher risk of developing type 2 diabetes, while the risk for people who slept three to four hours was 41% higher, compared to people who slept seven to eight hours.</p> <p>One limitation is the study defined a healthy diet based on the number of servings of fruit, vegetables, red meat and fish a person consumed over a day or a week. In doing so, it didn’t consider how dietary patterns such as time-restricted eating or the Mediterranean diet may modify the risk of diabetes among those who slept less.</p> <p>Also, information on participants’ sleep quantity and diet was only captured at recruitment and may have changed over the course of the study. The authors acknowledge these limitations.</p> <h2>Why might short sleep increase diabetes risk?</h2> <p>In people with <a href="https://www.diabetesaustralia.com.au/about-diabetes/type-2-diabetes/">type 2 diabetes</a>, the body becomes resistant to the effects of a hormone called insulin, and slowly loses the capacity to produce enough of it in the pancreas. Insulin is important because it regulates glucose (sugar) in our blood that comes from the food we eat by helping move it to cells throughout the body.</p> <p>We don’t know the precise reasons why people who sleep less may be at higher risk of type 2 diabetes. But <a href="https://doi.org/10.7759/cureus.23501">previous research</a> has shown sleep-deprived people often have increased <a href="https://doi.org/10.1186/1476-511X-9-125">inflammatory markers</a> and <a href="https://doi.org/10.1007/s00125-015-3500-4">free fatty acids</a> in their blood, which <a href="https://doi.org/10.1007/s11892-018-1055-8">impair insulin sensitivity</a>, leading to <a href="https://doi.org/10.7759/cureus.23501">insulin resistance</a>. This means the body struggles to use insulin properly to regulate blood glucose levels, and therefore increases the risk of type 2 diabetes.</p> <p>Further, people who don’t sleep enough, as well as people who sleep in irregular patterns (such as shift workers), experience disruptions to their body’s natural rhythm, known as the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5995632/">circadian rhythm</a>.</p> <p>This can interfere with the release of hormones like <a href="https://doi.org/10.1210/edrv.18.5.0317">cortisol, glucagon and growth hormones</a>. These hormones are released through the day to meet the body’s changing energy needs, and normally keep blood glucose levels nicely balanced. If they’re compromised, this may reduce the body’s ability to handle glucose as the day progresses.</p> <p>These factors, and <a href="https://www.science.org/doi/10.1126/sciadv.aar8590">others</a>, may contribute to the increased risk of type 2 diabetes seen among people sleeping less than six hours.</p> <p>While this study primarily focused on people who sleep eight hours or less, it’s possible longer sleepers may also face an increased risk of type 2 diabetes.</p> <p>Research has previously shown a U-shaped correlation between sleep duration and type 2 diabetes risk. A <a href="https://doi.org/10.2337/dc14-2073">review</a> of multiple studies found getting between seven to eight hours of sleep daily was associated with the lowest risk. When people got less than seven hours sleep, or more than eight hours, the risk began to increase.</p> <p>The reason sleeping longer is associated with increased risk of type 2 diabetes may be linked to <a href="https://doi.org/10.2337/dc15-0186">weight gain</a>, which is also correlated with longer sleep. Likewise, people who don’t sleep enough are more likely to be <a href="https://doi.org/10.1016/j.sleh.2017.07.013">overweight or obese</a>.</p> <h2>Good sleep, healthy diet</h2> <p>Getting enough sleep is an important part of a healthy lifestyle and may reduce the risk of type 2 diabetes.</p> <p>Based on this study and other evidence, it seems that when it comes to diabetes risk, seven to eight hours of sleep may be the sweet spot. However, other factors could influence the relationship between sleep duration and diabetes risk, such as individual differences in sleep quality and lifestyle.</p> <p>While this study’s findings question whether a healthy diet can mitigate the effects of a lack of sleep on diabetes risk, a wide range of evidence points to the benefits of <a href="https://www.who.int/initiatives/behealthy/healthy-diet">healthy eating</a> for overall health.</p> <p>The <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2815684">authors of the study</a> acknowledge it’s not always possible to get enough sleep, and suggest doing <a href="https://pubmed.ncbi.nlm.nih.gov/33137489/">high-intensity interval exercise</a> during the day may offset some of the potential effects of short sleep on diabetes risk.</p> <p>In fact, exercise <a href="https://doi.org/10.1016/j.jshs.2023.03.001">at any intensity</a> can improve blood glucose levels.<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/225179/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/giuliana-murfet-1517219">Giuliana Murfet</a>, Casual Academic, Faculty of Health, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a> and <a href="https://theconversation.com/profiles/shanshan-lin-1005236">ShanShan Lin</a>, Senior Lecturer, School of Public Health, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

The unique travel hack that is guaranteed to help beat jet lag

<p dir="ltr">Experts have revealed how to beat jet lag on your next overseas holiday, and it all comes down to your modes of transport. </p> <p dir="ltr">Sleep researchers said it's good news for cruise lovers, as exposure to sea air and bright natural light improves sleep to cure the annoying condition quickly.</p> <p dir="ltr">Some experts say to avoid travelling by plane all together, and always opt for cruising holidays instead. </p> <p dir="ltr">However, if you have to travel to your cruise by plane, being on board is a great way to tackle the dreadful feeling, compared with holidaying on land, Panache Cruises said.</p> <p dir="ltr">Dr Lindsay Browning, expert at Trouble Sleeping said exposing yourself to bright lights at the right time after a long-haul flight is one of the most powerful things we can do to boost and help shift circadian rhythm, and being on a ship is the perfect place for that.</p> <p dir="ltr">"As a general rule, you want to get lots of bright light exposure during the daytime and avoid light at night," Browning said.</p> <p dir="ltr">"When travelling on a cruise ship, you will naturally get a lot of bright light exposure during the day, helping your circadian rhythm.”</p> <p dir="ltr">"Further, when travelling by ship you will have a cabin with a proper bed and curtain, enabling you to sleep at night when you want to."</p> <p dir="ltr">The company claimed research showed how prolonged exposure to sea air can improve blood oxygen levels, boost vitamin D, and improve breathing leading to higher-quality sleep, helping to rid travellers of pesky jet lag so they can enjoy their holidays. </p> <p dir="ltr"><em>Image credits: Getty Images</em></p>

Asking ChatGPT a health-related question? Better keep it simple

<p>It’s tempting to <a href="https://cosmosmagazine.com/news/chatgpt-and-dr-google/">turn to search engines</a> to seek out health information, but with the rise of large language models, like ChatGPT, people are becoming more and more likely to depend on AI for answers too.</p> <div class="copy"> <p>Concerningly, an Australian study has now found that the more evidence given to <a href="https://cosmosmagazine.com/technology/chatgpt-an-intimate-companion/">ChatGPT</a> when asked a health-related question, the less reliable it becomes.</p> <p>Large language models (LLM) and artificial intelligence use in health care is still developing, creating a  a critical gap when providing incorrect answers can have serious consequences for people’s health.</p> <p>To address this, scientists from Australia’s national science agency, CSIRO, and the University of Queensland (UQ) explored a hypothetical scenario: an average person asking ChatGPT if ‘X’ treatment has a positive effect on condition ‘Y’.</p> <p>They presented ChatGPT with 100 questions sourced from the <a href="https://trec-health-misinfo.github.io/" target="_blank" rel="noopener">TREC Health Misinformation track</a> – ranging from ‘Can zinc help treat the common cold?’ to ‘Will drinking vinegar dissolve a stuck fish bone?’</p> <p>Because queries to search engines are typically shorter, while prompts to a LLM can be far longer, they posed the questions in 2 different formats: the first as a simple question and the second as a question biased with supporting or contrary evidence.</p> <p>By comparing ChatGPT’s response to the known correct response based on existing medical knowledge, they found that ChatGPT was 80% accurate at giving accurate answers in a question-only format. However, when given an evidence-biased prompt, this accuracy reduced to 63%, which was reduced again to 28% when an “unsure” answer was allowed. </p> <p>“We’re not sure why this happens,” says CSIRO Principal Research Scientist and Associate Professor at UQ, Dr Bevan Koopman, who is co-author of the paper.</p> <p>“But given this occurs whether the evidence given is correct or not, perhaps the evidence adds too much noise, thus lowering accuracy.”</p> <p>Study co-author Guido Zuccon, Director of AI for the Queensland Digital Health Centre at UQ says that major search engines are now integrating LLMs and search technologies in a process called Retrieval Augmented Generation.</p> <p>“We demonstrate that the interaction between the LLM and the search component is still poorly understood, resulting in the generation of inaccurate health information,” says Zuccon.</p> <p>Given the widespread popularity of using LLMs online for answers on people’s health, Koopman adds, we need continued research to inform the public about risks and to help them optimise the accuracy of their answers.</p> <p>“While LLMs have the potential to greatly improve the way people access information, we need more research to understand where they are effective and where they are not.”</p> <p><em>Image credits: Getty Images</em></p> <div> <p align="center"> </p> </div> <p><em><img id="cosmos-post-tracker" style="opacity: 0; height: 1px!important; width: 1px!important; border: 0!important; position: absolute!important; z-index: -1!important;" src="https://syndication.cosmosmagazine.com/?id=301406&amp;title=Asking+ChatGPT+a+health-related+question%3F+Better+keep+it+simple" width="1" height="1" loading="lazy" aria-label="Syndication Tracker" data-spai-target="src" data-spai-orig="" data-spai-exclude="nocdn" /></em><em><a href="https://cosmosmagazine.com/technology/ai/asking-chatgpt-a-health-related-question-better-keep-it-simple/">This article</a> was originally published on <a href="https://cosmosmagazine.com">Cosmos Magazine</a> and was written by <a href="https://cosmosmagazine.com/contributor/imma-perfetto/">Imma Perfetto</a>. </em></div>

Christina Applegate's devastating health update

<p>Christina Applegate has shared a heart-wrenching health update, sharing that she is currently unable to walk or use her shower. </p> <p>The actress, who has been battling multiple sclerosis (MS) since 2021, spoke candidly on her <em>MeSsy</em> podcast that she is going through a difficult relapse of her chronic illness, which is getting in the way of being able to complete basic tasks. </p> <p>“I’m gonna be honest with you, I need to buy stock in Cottonelle because I haven’t taken a shower in three weeks,” Applegate told podcast co-host Jamie Lynn-Sigler, who also suffers from MS.</p> <p>She continued, “Because I can’t stand in my shower. There’s no f****** way I can use my shower.”</p> <p>“I have such a small bench and my a** is so huge these days that I can’t sit on it, it’s like I slip right off of it,” she added. “So, I’ve been Cottonelle-ing my body.”</p> <p>At the beginning of the episode, Applegate detailed the severity of her symptoms and how they were impacting different areas of her body.</p> <p>"Intense pain in my legs, not being able to walk to the bathroom without feeling like I'm going to fall, insane tingling, spurts of tingles," she said of the pain she's currently experiencing.</p> <p>"I haven't slept for 24 hours because my eye is doing something weird, where every time I close my eye to go to sleep, my right eye starts to shift like this."</p> <p>Applegate noted how unusual the symptoms in her legs were, saying, "My legs have never been this bad... so I don't know what's going on, like, no energy."</p> <p>"[My] Legs are just done. I can't get circulation, I can't get them to stop hurting."</p> <p dir="ltr">Christina first revealed her diagnosis in August 2021, sharing the news on Twitter and thanking everyone for their support. </p> <p dir="ltr">“Hi friends. A few months ago I was diagnosed with MS. It’s been a strange journey. But I have been so supported by people that I know who also have this condition. It’s been a tough road. But as we all know, the road keeps going. Unless some a**hole blocks it,” her tweet reads.</p> <p dir="ltr">According to MS Australia, MS is the most common acquired chronic neurological disease in young adults with diagnosis occurring between the ages of 20 to 40.</p> <p dir="ltr"><em>Image credits: Getty Images </em></p>

Silent cancers: here’s what you need to know when there are no obvious symptoms

<p><em><a href="https://theconversation.com/profiles/justin-stebbing-1405462">Justin Stebbing</a>, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a></em></p> <p>The recent revelations about the Princess of Wales’s <a href="https://www.bbc.com/news/uk-68640917">cancer diagnosis</a> highlight a crucial aspect of cancer detection – the disease’s sometimes silent nature.</p> <p>Silent cancers are those without noticeable symptoms. They pose a unique challenge in early detection and treatment.</p> <p>Contrary to common perception, cancer does not always announce its presence through overt symptoms or obvious signs. Many people receive a <a href="https://academic.oup.com/clinchem/article-abstract/70/1/179/7283928">cancer diagnosis incidentally</a>, when it’s found during routine medical examinations or investigations for unrelated health concerns – as seems to be the case for both <a href="https://www.wsj.com/health/kate-middleton-catherine-cancer-what-is-preventative-chemotherapy-9625370d">the princess</a> and <a href="https://www.bbc.co.uk/news/health-68171163">King Charles III</a>.</p> <p>While even silent cancers can sometimes be <a href="https://pubmed.ncbi.nlm.nih.gov/22584215/">aggressive and advance rapidly</a>, they can also remain <a href="https://pubmed.ncbi.nlm.nih.gov/20363069/">dormant</a> for years or <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8819710/">even decades</a>. Some <a href="https://ascopubs.org/doi/10.14694/EdBook_AM.2012.32.98">prostate</a>, <a href="https://ascopubs.org/doi/10.14694/EdBook_AM.2012.32.301">breast</a> and <a href="https://www.frontiersin.org/journals/endocrinology/articles/10.3389/fendo.2020.571421/full">thyroid</a> cancers, for example, <a href="https://www.tmlep.com/clinical-learning/2023-01-23-when-did-this-tumour-start-the-need-for-a-gompertzian-understanding-of-tumour-growth-kinetics">often evolve slowly</a> without obvious symptoms or spreading beyond the original area.</p> <p>Research suggests that some of these cancers are <a href="https://www.frontiersin.org/journals/endocrinology/articles/10.3389/fendo.2020.571421/full">overtreated</a>. Sometimes patients are best left alone or treated much more gently, perhaps even without medical intervention, using a <a href="https://www.nejm.org/doi/full/10.1056/nejmoa1311593">“watch and wait”</a> strategy. This approach may be taken with prostate cancer in the elderly, for example.</p> <h2>The importance of early diagnosis</h2> <p>Whatever the cancer, it’s always important to get an early diagnosis though – and for silent cancers, this is obviously a challenge.</p> <p>Some cancer symptoms <a href="https://pubmed.ncbi.nlm.nih.gov/36702593/">can be vague</a> and easily mistaken for benign ailments. Fatigue, unexplained weight loss and persistent pain are among the nonspecific symptoms that may signal an underlying malignancy. But such symptoms can be misinterpreted or easily dismissed, which contributes to delayed diagnosis and treatment.</p> <figure><iframe src="https://www.youtube.com/embed/MGMy6BzBvp0?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>Fortunately, in many countries including the UK, we have <a href="https://www.england.nhs.uk/cancer/early-diagnosis/screening-and-earlier-diagnosis/">screening</a> tests for diseases like breast or colon cancer, to increase early diagnoses.</p> <p>Early diagnosis is a <a href="https://acsjournals.onlinelibrary.wiley.com/doi/full/10.1002/cncr.32887">key factor</a> for successful cancer treatment. Detecting cancer in its silent phase offers a window of opportunity for early intervention and improved outcomes. The discovery of asymptomatic cancers through diagnostic imaging or screening tests underscores the importance of these proactive healthcare measures.</p> <p>Identifying cancer at an early stage means the disease is confined to its site of origin, smaller and potentially easier to cure. Diagnosing a smaller cancer often means that if an operation is needed, it may be a less invasive surgery. There may also be a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6825992/">lower chance</a> of needing post-operative preventative chemotherapy, to mop up any residual cells.</p> <p>Colorectal cancer (CRC) is a good example to show the critical importance of screening. Studies show that patients who participate in CRC <a href="https://www.nice.org.uk/guidance/dg56/chapter/1-Recommendations">screening</a>, such as colonoscopies or tests that look for blood in the stool, are more likely to be diagnosed while asymptomatic and have more positive prognoses after treatment. Those diagnosed with CRC after showing symptoms, such as rectal bleeding or changes in bowel habits, tend to have more <a href="https://bmjopengastro.bmj.com/content/4/1/e000146%20">advanced tumors and poorer outcomes</a>.</p> <figure><iframe src="https://www.youtube.com/embed/nA9_Io3LDpA?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>Public health initiatives aimed at raising awareness about the importance of both cancer screening and symptom recognition play a pivotal role in reducing diagnostic delays. Empowering people to engage in <a href="https://healthcaredelivery.cancer.gov/prevention/#:%7E:text=Cancer%20can%20be%20prevented%20through,they%20are%20more%20easily%20treated.">preventive healthcare measures</a> such as HPV vaccinations and lifestyle changes that decrease risk can facilitate early detection and intervention, potentially altering the trajectory of the disease.</p> <h2>Biomarker discovery</h2> <p>The latest advances in diagnostic technologies, often known as <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8012218/#:%7E:text=During%20biomarker%20discovery%2C%20evaluation%20of,design%20of%20future%20validation%20studies.">“biomarker discovery”</a>, hold promise for improving early detection rates and refining treatment strategies for silent cancers. From <a href="https://www.cancer.gov/publications/dictionaries/cancer-terms/def/molecular-profiling">molecular profiling</a> to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9922467/">liquid biopsy techniques</a> (blood tests to diagnose cancer), innovative approaches are reshaping the landscape of cancer diagnosis, offering new avenues for personalised and precision medicine.</p> <p>For example, I worked with a team using blood tests to identify cancers in more than <a href="https://www.nature.com/articles/s41388-023-02591-z">1,000 women recalled after screening for mammography</a>. We looked at the DNA that tumour cells release – so-called <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10496721/">cell-free DNA</a> – and also metabolomics (rare markers related to metabolism in the blood). From this information, we found healthy patients, benign disease, pre-cancer and breast cancer. Although there’s increasing awareness and use of this <a href="https://www.sciencedirect.com/science/article/abs/pii/S1769721218307110">approach in Europe</a>, it isn’t standard in the UK.</p> <p>Asymptomatic cancers represent a formidable challenge for patient care. But, by encouraging patients to adopt preventive lifestyles and engage with screenings and tests, asymptomatic cancers don’t have to be a hidden threat to health.<!-- Below is The Conversation's page counter tag.

12 best yoga poses to strengthen bones

<p><strong>A bone-health doctor lists the 12 best yoga poses to strengthen bones</strong></p> <p>If you’re like many yoga lovers, you appreciate how this one physical activity can be so beneficial, while simultaneously so gentle. Few other practises stretch your body, calm your mind or help regulate vitals, such as your heart rate and blood pressure, in quite the way a regular yoga session can do.</p> <p>Researcher and rehabilitation doctor, Dr Loren Fishman has also been a practitioner of yoga for 50 years and is the creator of ‘the Fishman method’ of yoga for osteoporosis. In a conversation with Reader’s Digest, Dr Fishman points out that for all its advantages, yoga can also provide a powerful boost to your long-term bone density. In particular, Dr Fishman published 12 yoga poses in Orthopedic Nursing that are particularly great for strengthening your bones.</p> <p>Of these 12 poses Dr Fishman says: “They all work by putting pressure on the bones of sufficient magnitude and duration.” He says this can “stimulate the osteoblasts to make more bone”, thanks to their placement of “maximum torque, compression or pressure” on particular body parts, as outlined below.</p> <p>So, while a good yoga session is a helpful tool to help you get through the week, its effects are longer-lasting than you realised.</p> <p>Keep reading for the 12 best yoga poses to strengthen your bones. (“With all poses, remember not to round the spine as you go into and out of the poses, and within the poses themselves,” Dr Fishman advises.)</p> <p><strong>1. Tree pose (Vriksasana)</strong></p> <p>Tree pose has a special way of calling you to stillness. Dr Fishman says tree pose also adds pressure that can strengthen the upper femur and hip. He adds that a study at the University of Southern California (USC) showed a 60 per cent increase in pressure, even with the foot placed three-quarters down the calf.</p> <p>Dr Fishman says tree pose is “also extremely valuable for improving balance and avoiding falls,” although he reminds us that the raised foot should always go above or below the knee – never directly on the knee joint.</p> <p><strong>2. Triangle pose (Trikonasana)</strong></p> <p>Triangle pose “puts torque on the lumbar spine, the neck of the femur, the hips and ribs,” Dr Fishman says, adding that this is another pose that will help improve balance.</p> <p><strong>3. Reverse Triangle Pose (Parivrtta Trikonasan) </strong></p> <p>Dr Fishman says great pressures develop on the proximal femurs (very top of the femur bone that connects with the hip joint) in this pose, as well as the hip and lower back. Reverse triangle also puts helpful pressure in the ribs and wrists and is “a very powerful balance-improver.”</p> <p><strong>4. Warrior 2 (Virabhadrasana II)</strong></p> <p>“Fabulous mechanical disadvantage means great pressure on the entire forward (bent leg) femur,” Dr Fishman says of full warrior pose. He explains that “the straight leg’s rotation works on the head of femur and hip,” helping to strengthen the upper leg and hip. This is yet another pose that he says helps with balance.</p> <p><strong>5. Side angle pose (Parsvakonasana)</strong></p> <p>Another boon for balance, Dr Fishman says side angle pose torques the lower back and the top of the femur – all good things – and stimulates the bone-making cells of the hip, too.</p> <p><strong>6. Locust pose (Salabhasana)</strong></p> <p>Locust pose “raises pressures, which stimulate bone-making in the posterior elements of the spine,” Dr Fishman says, while it also helps balance some the forward focus on the ribs of the earlier poses. Locust pose also strengthens extensor muscles of the back to improve posture and reverse curvature of the spine in the upper back, which can lead to fractures.</p> <p><strong>7. Bridge pose (Setu Bandhasana)</strong></p> <p>Dr Fishman says bridge pose can help strengthen the ribs and lower regions of the spine.</p> <p><strong>8. Reclining hand to big toe (Supta Padangusthasana I)</strong></p> <p>Also known to be a good hamstring stretch, this pose facilitates “extreme pressure brought to bear on relevant sections” of the femur, hip, pelvis (specifically the sitz bones) and spine.</p> <p>Seated versions of this and the following pose offer less intensity, but Dr Fishman cautions for both: “The seated versions have the potential to be dangerous. Keep the spine straight and against the back of the chair. Do not round the back.”</p> <p><strong>9. Supine hand to big toe 2 (Supta Padangusthasana II)</strong></p> <p>In the side extension variation of this pose, there is “extreme pressure brought to bear” on the upper femur, hip, pubis, ribs, and spine, he says.</p> <p><strong>10. Straight-legged twist (Marichyasana)</strong></p> <p>This “puts great pressure” on the sitz bones and pelvis, as well as “great but safe pressure” on the spine.</p> <p><strong>11. Bent-leg twist (Matsyendrasana)</strong></p> <p>The bent-leg twist “puts great pressure” on the upper femur and pelvis, plus “great but safe pressure” on the vertebra. Dr Fishman suggests you should hug the leg to ensure a straight spine.</p> <p><strong>12. Corpse pose (Savasana)</strong></p> <p>Truthfully, Dr Fishman says, Savasana is “of little value for the bones per se, but truly important at the end of the session for mental and general physiological health.” That’s good enough for us.</p> <p><em><span id="docs-internal-guid-68140ce3-7fff-bd62-dea6-7b47a6dfe42b">Written by Jennifer Huizen and Kristine Gasbarre.

How to fall asleep without sleeping pills: 7 natural sleep aids that actually work

<p>It’s 3am and you’re suddenly wide awake. Try these seven science-backed strategies to fall back to sleep fast.</p> <p><strong>Give meditation a try </strong></p> <p>As a mindfulness coach, I’m very aware of the day-to-day anxieties and worries that can interfere with a good night’s sleep. One of the most effective natural sleep aids is a quick meditation session to ease yourself out of those stresses. If you’ve never meditated before, you’ll likely find the meditation interrupted by thoughts flashing through your mind.</p> <p>It’s important for you to know that this isn’t a failure on your part, and that you aren’t doing anything wrong. Thinking is just what the brain does, as naturally as lungs take in air. The point is to be non-judgmental yet aware of your thoughts, bodily experiences and breath, moment by moment.</p> <p><strong>Stop wanting to fall asleep</strong></p> <p>It’s counterintuitive, isn’t it? Sometimes trying too hard to do something is the very thing that prevents us from achieving it – and that’s never more true than when it comes to falling asleep. Desperately wanting to sleep will only stoke anxieties that will further stress your brain, essentially feeding it the message that it’s not safe to sleep.</p> <p>Throw in those worries about your to-do list at work the following day, and the whole thing can snowball into a panic attack. Try letting go of that feeling that you absolutely must sleep now, and observe your own anxieties for what they are without judgment. When you stop looking at sleep as a goal, you’ll find it easier to fall asleep.</p> <p><strong>Start a journal </strong></p> <p>If you find yourself struggling to fall asleep, pick up a pen and paper (not your phone!), and start writing: simply scribble down an account of what’s going on inside your head. Although there’s no “right” way to journal, you might start by listing the events of your day, and from there, how those events and encounters made you feel.</p> <p>Building this structured picture of your thoughts may help you see that the problem that’s keeping you up at night, and is likely less overwhelming than you thought. Why my insistence on a pen and paper? First off, studies show the simple motor action that’s involved in the act of handwriting has a calming effect. Secondly, the light emitted by laptops and phones isn’t conducive to falling asleep.</p> <p><strong>Find yourself a "3am friend"</strong></p> <p>Some of us are lucky to have a ‘3am friend’, that close confidant you can call up in the wee hours knowing that they won’t hold it against you in the morning. Although it’s great to have someone to talk to when you want to fall asleep, it’s important that the conversation doesn’t just rehash the anxieties that are preventing you from catching shut-eye in the first place.</p> <p>Rather than using the call to seek solutions for those issues, talk about things that calm your nerves, or even have them assist you in deep breathing. It may sound silly, but doing a series of deep, relaxing breaths can help you let go of the troubles that are keeping you wide awake.</p> <p><strong>Take a warm shower</strong></p> <p>Taking a warm shower not only relaxes your muscles and soothes minor aches and pains, but it also raises your core body temperature. As soon as you step out of the shower, your body starts working at lowering that temperature, which is something that normally happens when you’re falling asleep naturally.</p> <p>(That’s why we always feel the need for a blanket when we sleep, no matter how warm it is!) By kick-starting that temperature-lowering process, you’re tricking your body into falling asleep fast.</p> <p><strong>Stretch yourself to sleep </strong></p> <p>Anxiety keeping you up? Research suggests mild stretching can help take the edge off and relax muscles that have become stiff and sore after a long day. We’re not talking intricate yoga poses or acrobatics here, either: Simple stretches like an overhead arm stretch and bending over to touch your toes should do the trick. Ramp up the relaxation potential with a soundtrack of ambient noise at a volume that’s just barely audible.</p> <p>There are plenty of white noise apps that are free to download, but soft music can work as well (so long as there are no lyrics). Just remember, if you’re using an electronic device to play these sleep-promoting sounds, make sure it’s placed screen-down so you’re not distracted by the light it emits.</p> <p><strong>Read (or listen!) to something new</strong></p> <p>When you’re struggling with insomnia, it might be tempting to pull an old favourite off the bookshelf. In reality, it’s better to read or listen to an audio book that covers a topic on which you know absolutely nothing. New information, while taking attention away from the stressors that are keeping you up at night, gives your brain enough of a workout to make it tire more quickly than when it’s engaged with familiar subjects and concepts.</p> <p>Again, if it’s an audio book or podcast you’re listening to, make sure the light-emitting side of the device is face down to keep the room as dark as possible. Darkness and warmth play an essential part in the production and maintenance of melatonin, the hormone that plays the central role falling asleep.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article by Deepak Kashyap </em><em>originally appeared on <a href="https://www.readersdigest.co.nz/healthsmart/conditions/sleep/how-to-fall-asleep-without-sleeping-pills-7-natural-sleep-aids-that-actually-work" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

How to look after your mental health while packing up Mum or Dad’s home

<p><em><a href="https://theconversation.com/profiles/erika-penney-1416241">Erika Penney</a>, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a>; <a href="https://theconversation.com/profiles/alice-norton-1516505">Alice Norton</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/avalon-tissue-1515840">Avalon Tissue</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>So Mum or Dad has died, or moved to aged care, and now you’ve got to pack up their house. It’s a huge job and you’re dreading it.</p> <p>It’s normal to feel grief, loss, guilt, exhaustion or even resentment at being left with this job.</p> <p>So how can you look after your mental health while tackling the task?</p> <h2>It’s OK to feel a lot of feelings</h2> <p>Research has documented how this task can exert an intense <a href="https://www.tandfonline.com/doi/full/10.1080/15267431.2021.1943399">physical and emotional toll</a>.</p> <p>This can be more intense for those who had strained – or even <a href="https://journals.sagepub.com/doi/epub/10.1177/0030222819868107">traumatic</a> – relationships with the person whose house they’re packing up.</p> <p>Decisions around distributing or discarding items can, in some families, bring up painful reminders of the past or end up <a href="https://journals.sagepub.com/doi/10.1177/1074840711428451">replaying strained dynamics</a>.</p> <p>Family members who were carers for the deceased may feel exhaustion, overwhelm, <a href="https://onlinelibrary.wiley.com/doi/abs/10.1002/hec.1512?sid=vendor%3Adatabase">burnout</a> or a sense of injustice they must now continue to be responsible for their loved one’s affairs. Grief can be compounded by the practical challenges of deciding how to <a href="https://doi.org/10.1016/0148-2963(94)00054-I">store or discard belongings</a>, <a href="https://www.jstor.org/stable/30000385">arrange the funeral</a>, execute the will, deal with the aged care place or, in some cases, navigate legal disputes.</p> <p>But packing up the house may also be cathartic or helpful. <a href="https://www.tandfonline.com/doi/full/10.1080/15267431.2021.1943399">Research</a> has shown how the task of cleaning out a loved one’s belongings can provide an opportunity for family and friends to talk, share memories, and make sense of what has just happened.</p> <p>It’s also normal to grieve before someone dies. What psychologists call “<a href="https://pubmed.ncbi.nlm.nih.gov/29206700/">anticipatory</a> grief” can happen to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1615888/">relatives packing up the house</a> of a parent who has moved to aged care or palliative care.</p> <h2>What to do with all this stuff?</h2> <p><a href="https://doi.org/10.1016/0148-2963(94)00054-I">Some</a> treat their loved one’s items with sanctity, holding onto as many of their belongings as possible and creating “shrines” in their honour.</p> <p>Others alleviate the weight of grief by clearing out a loved one’s house as soon as possible, giving away, selling or discarding as much as they can.</p> <p>But if you experience a mix of these – enthusiastically getting rid of some stuff, while desperately wanting to hold onto other things – that’s OK too.</p> <p>One <a href="https://www.tandfonline.com/doi/abs/10.1080/10253866.2017.1367677">study</a> identified a process punctuated by four key periods:</p> <ol> <li> <p>numbness and overwhelm at the task of packing the house</p> </li> <li> <p>yearning to maintain a link to the loved through their belongings</p> </li> <li> <p>working through grief, anger and guilt regarding the loved one and the task of managing their belongings, and</p> </li> <li> <p>healing and making sense of the relationship with the deceased and their belongings.</p> </li> </ol> <p>However, it is important to note everyone’s approach is different and there is no “right” way to do the clean out, or “right” way to feel.</p> <h2>Caring for your mental health during the clean out</h2> <p>To care for your mental health during these difficult times, you might try to:</p> <ul> <li> <p>make space for your feelings, whether it’s sadness, loss, resentment, anger, relief or all the above. There is no right or wrong way to feel. <a href="https://guilfordjournals.com/doi/abs/10.1521/jscp.2011.30.2.163">Accepting</a> your emotions is healthier than suppressing them</p> </li> <li> <p>share the load. <a href="https://onlinelibrary.wiley.com/doi/abs/10.1046/j.1365-2648.1999.01220.x">Research</a> has shown practical support from close friends and family can help a lot with grief. Accept help with packing, planning, dealing with removalists, selling or donating items and cleaning. Don’t be afraid to reduce your mental load by delegating tasks to friends, who are likely wondering how they can help</p> </li> <li> <p>take a systematic approach. Break tasks into their smallest component. For example, aim to clean out a drawer instead of an entire bedroom. This can help the mental and physical task feel more manageable</p> </li> <li> <p>reflect on what’s meaningful to you. Some belongings will have <a href="https://doi.org/10.1016/0148-2963(94)00054-I">meaning</a>, while others will not. What was valuable to the deceased may not be valuable to you. Things they probably saw as pretty worthless (a handwritten shopping list, an old sewing kit) may be very meaningful to you. Ask yourself whether retaining a small number of meaningful possessions would allow you to maintain a connection with your loved one, or if clearing out the space and discarding the items is what you need</p> </li> <li> <p>share your story. When you feel ready, share your “<a href="https://www.tandfonline.com/doi/full/10.1080/15267431.2021.1943399">cleaning out the closet</a>” story with trusted friends and family. Storytelling allows the deceased to live on in memory. <a href="https://onlinelibrary.wiley.com/doi/abs/10.1046/j.1365-2648.1999.01220.x">Research</a> also suggests we cope better with bereavement when friends and relatives make time to hear our feelings</p> </li> <li> <p>remember that professional help is available. Just as a solicitor can help with legal disputes, a mental health professional can help you process your feelings.</p> </li> </ul> <p>The home of your loved one is not merely a place where they lived, but a space filled with meaning and stories.</p> <p>Packing up the house of a loved one can be incredibly daunting and challenging, but it can also be an important part of your grieving process.</p> <p><em>If this article has raised issues for you, or if you’re concerned about someone you know, call Lifeline on 13 11 14.</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/223956/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/erika-penney-1416241">E<em>rika Penney</em></a><em>, Lecturer in Clinical Psychology, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a>; <a href="https://theconversation.com/profiles/alice-norton-1516505">Alice Norton</a>, Lecturer in Psychology, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/avalon-tissue-1515840">Avalon Tissue</a>, Associate Lecturer in Clinical Psychology, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How much stress is too much? A psychiatrist explains the links between toxic stress and poor health − and how to get help

<p><a href="https://theconversation.com/profiles/lawson-r-wulsin-1493655">La<em>wson R. Wulsin</em></a><em>, <a href="https://theconversation.com/institutions/university-of-cincinnati-1717">University of Cincinnati </a></em></p> <p>COVID-19 taught most people that the line between tolerable and toxic stress – defined as persistent demands that lead to disease – varies widely. But some people will age faster and die younger from toxic stressors than others.</p> <p>So how much stress is too much, and what can you do about it?</p> <p>I’m a <a href="https://researchdirectory.uc.edu/p/wulsinlr">psychiatrist specializing in psychosomatic medicine</a>, which is the study and treatment of people who have physical and mental illnesses. My research is focused on people who have psychological conditions and medical illnesses as well as those whose stress exacerbates their health issues.</p> <p>I’ve spent my career studying mind-body questions and training physicians to treat mental illness in primary care settings. My <a href="https://www.cambridge.org/core/books/toxic-stress/677FA62B741540DBDB53E2F0A52A74B1">forthcoming book</a> is titled “Toxic Stress: How Stress is Killing Us and What We Can Do About It.”</p> <p>A 2023 study of stress and aging over the life span – one of the first studies to confirm this piece of common wisdom – found that four measures of stress all speed up the pace of biological aging in midlife. It also found that persistent high stress ages people in a comparable way to the <a href="https://doi.org/10.1097/PSY.0000000000001197">effects of smoking and low socioeconomic status</a>, two well-established risk factors for accelerated aging.</p> <figure><iframe src="https://www.youtube.com/embed/yiglpsqv5ik?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">Children with alcoholic or drug-addicted parents have a greater risk of developing toxic stress.</span></figcaption></figure> <h2>The difference between good stress and the toxic kind</h2> <p>Good stress – a demand or challenge you readily cope with – is good for your health. In fact, the rhythm of these daily challenges, including feeding yourself, cleaning up messes, communicating with one another and carrying out your job, helps to regulate your stress response system and keep you fit.</p> <p>Toxic stress, on the other hand, wears down your stress response system in ways that have lasting effects, as psychiatrist and trauma expert Bessel van der Kolk explains in his bestselling book “<a href="https://www.penguinrandomhouse.com/books/313183/the-body-%20keeps-the-score-by-bessel-van-der-kolk-md/">The Body Keeps the Score</a>.”</p> <p>The earliest effects of toxic stress are often persistent symptoms such as headache, fatigue or abdominal pain that interfere with overall functioning. After months of initial symptoms, a full-blown illness with a life of its own – such as migraine headaches, asthma, diabetes or ulcerative colitis – may surface.</p> <p>When we are healthy, our stress response systems are like an orchestra of organs that miraculously tune themselves and play in unison without our conscious effort – a process called self-regulation. But when we are sick, some parts of this orchestra struggle to regulate themselves, which causes a cascade of stress-related dysregulation that contributes to other conditions.</p> <p>For instance, in the case of diabetes, the hormonal system struggles to regulate sugar. With obesity, the metabolic system has a difficult time regulating energy intake and consumption. With depression, the central nervous system develops an imbalance in its circuits and neurotransmitters that makes it difficult to regulate mood, thoughts and behaviors.</p> <h2>‘Treating’ stress</h2> <p>Though stress neuroscience in recent years has given researchers like me <a href="https://doi.org/10.1097/PSY.0000000000001051">new ways to measure and understand stress</a>, you may have noticed that in your doctor’s office, the management of stress isn’t typically part of your treatment plan.</p> <p>Most doctors don’t assess the contribution of stress to a patient’s common chronic diseases such as diabetes, heart disease and obesity, partly because stress is complicated to measure and partly because it is difficult to treat. In general, doctors don’t treat what they can’t measure.</p> <p>Stress neuroscience and epidemiology have also taught researchers recently that the chances of developing serious mental and physical illnesses in midlife rise dramatically when people are exposed to trauma or adverse events, especially during <a href="https://www.cdc.gov/violenceprevention/aces/ace-brfss.html">vulnerable periods such as childhood</a>.</p> <p>Over the past 40 years in the U.S., the alarming rise in <a href="https://www.cdc.gov/diabetes/health-equity/diabetes-by-the-numbers.html">rates of diabetes</a>, <a href="https://www.cdc.gov/nchs/data/hestat/obesity-child-17-18/overweight-obesity-child-H.pdf">obesity</a>, depression, PTSD, <a href="https://www.cdc.gov/nchs/products/databriefs/db433.htm">suicide</a> and addictions points to one contributing factor that these different illnesses share: toxic stress.</p> <p>Toxic stress increases the risk for the onset, progression, complications or early death from these illnesses.</p> <h2>Suffering from toxic stress</h2> <p>Because the definition of toxic stress varies from one person to another, it’s hard to know how many people struggle with it. One starting point is the fact that about 16% of adults report having been exposed to <a href="https://www.cdc.gov/violenceprevention/aces/fastfact.html">four or more adverse events in childhood</a>. This is the threshold for higher risk for illnesses in adulthood.</p> <p>Research dating back to before the COVID-19 pandemic also shows that about 19% of adults in the U.S. have <a href="https://doi.org/10.7249/TL221">four or more chronic illnesses</a>. If you have even one chronic illness, you can imagine how stressful four must be.</p> <p>And about 12% of the U.S. population <a href="https://blogs.worldbank.org/opendata/introducing-second-edition-world-banks-global-subnational-atlas-poverty">lives in poverty</a>, the epitome of a life in which demands exceed resources every day. For instance, if a person doesn’t know how they will get to work each day, or doesn’t have a way to fix a leaking water pipe or resolve a conflict with their partner, their stress response system can never rest. One or any combination of threats may keep them on high alert or shut them down in a way that prevents them from trying to cope at all.</p> <p>Add to these overlapping groups all those who struggle with harassing relationships, homelessness, captivity, severe loneliness, living in high-crime neighborhoods or working in or around noise or air pollution. It seems conservative to estimate that about 20% of people in the U.S. live with the effects of toxic stress.</p> <figure><iframe src="https://www.youtube.com/embed/WuyPuH9ojCE?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">Exercise, meditation and a healthy diet help fight toxic stress.</span></figcaption></figure> <h2>Recognizing and managing stress and its associated conditions</h2> <p>The first step to managing stress is to recognize it and talk to your primary care clinician about it. The clinician may do an assessment involving a <a href="https://doi.org/10.1097/PSY.0000000000001051">self-reported measure of stress</a>.</p> <p>The next step is treatment. Research shows that it is possible to retrain a dysregulated stress response system. This approach, <a href="https://lifestylemedicine.org/">called “lifestyle medicine</a>,” focuses on improving health outcomes through changing high-risk health behaviors and adopting daily habits that help the stress response system self-regulate.</p> <p>Adopting these lifestyle changes is not quick or easy, but it works.</p> <p>The <a href="https://www.cdc.gov/diabetes/prevention/index.html">National Diabetes Prevention Program</a>, the <a href="https://www.ornish.com/">Ornish “UnDo” heart disease program</a> and the <a href="https://www.ptsd.va.gov/understand_tx/tx_basics.asp">U.S. Department of Veterans Affairs PTSD program</a>, for example, all achieve a slowing or reversal of stress-related chronic conditions through weekly support groups and guided daily practice over six to nine months. These programs help teach people how to practice personal regimens of stress management, diet and exercise in ways that build and sustain their new habits.</p> <p>There is now strong evidence that it is possible to treat toxic stress in ways that improve health outcomes for people with stress-related conditions. The next steps include finding ways to expand the recognition of toxic stress and, for those affected, to expand access to these new and effective approaches to treatment.<!-- Below is The Conversation's page counter tag.

Vitamin D supplements can keep bones strong – but they may also have other benefits to your health

<p><em><a href="https://theconversation.com/profiles/martin-hewison-1494746">Martin Hewison</a>, <a href="https://theconversation.com/institutions/university-of-birmingham-1138">University of Birmingham</a></em></p> <p>Most of us don’t worry about getting vitamin D when the weather’s warm and the sun is shining. But as winter approaches, accompanied by overcast days and long nights, you may be wondering if it could be useful to take a vitamin D supplement – and what benefit it might have.</p> <p>During the summer, the best way to get vitamin D is by getting a bit of sunshine. Ultraviolet rays (specifically UVB, which have a shorter wavelength) interact with a form of cholesterol called <a href="https://www.ncbi.nlm.nih.gov/books/NBK278935/">7-dehydrocholesterol</a> in the skin, which is then converted into vitamin D.</p> <p>Because vitamin D production is dependent on UVB, this means our ability to make it <a href="https://www.nhs.uk/conditions/vitamins-and-minerals/vitamin-d/#:%7E:text=From%20about%20late%20March%2Fearly,enough%20vitamin%20D%20from%20sunlight.">declines in the winter months</a>. Vitamin D production also <a href="https://pubmed.ncbi.nlm.nih.gov/24494042/">depends on where you live</a>, with people living nearer to the equator making more vitamin D than those living nearer the poles.</p> <p>Vitamin D deficiency is a <a href="https://assets.publishing.service.gov.uk/media/5a804e36ed915d74e622dafa/SACN_Vitamin_D_and_Health_report.pdf">problem in the UK</a> during the winter months. This is due to its northerly position and cloudy weather, and lack of time spent outdoors.</p> <p>One study of over 440,000 people in the UK found that <a href="https://pubmed.ncbi.nlm.nih.gov/33309415/">18% were vitamin D deficient</a> during the winter months. Vitamin D deficiency was even higher in certain ethnic groups – with the data showing 57% of Asian participants and 38% of black participants were vitamin D deficient. This is because the melanin content of skin determines a person’s ability to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5946242/#:%7E:text=Skin%20pigmentation%2C%20i.e.%2C%20melanin%2C,%5B7%5D%20and%20more%20generally.">make UVB into vitamin D</a>.</p> <p>Given the prevalence of vitamin D deficiency in the UK, and the importance it has for our health, in 2016 the UK’s Science Advisory Council on Nutrition outlined recommendations for the <a href="https://www.gov.uk/government/publications/sacn-vitamin-d-and-health-report#:%7E:text=In%20a%20change%20to%20previous,aged%204%20years%20and%20older">amount of vitamin D</a> people should aim to get in the winter.</p> <p>They recommend people aim to get ten micrograms (or 400 IU – international units) of vitamin D per day. This would help people avoid severe deficiency. This can be achieved either by taking a supplement, or eating <a href="https://www.bhf.org.uk/informationsupport/heart-matters-magazine/nutrition/ask-the-expert/foods-high-in-vitamin-d">certain foods</a> that are rich in vitamin D – including fatty fish such as herring, mackerel and wild salmon. A 100 gram serving of fresh herring, for example, would have approximately five micrograms of vitamin D.</p> <p>The clearest benefit of taking a vitamin D supplement is for <a href="https://www.nhs.uk/conditions/vitamins-and-minerals/vitamin-d/">bone health</a>. In fact, vitamin D was <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3899558/">first discovered</a> 100 years ago because of its ability to prevent the disease rickets, which causes weak bones that bend.</p> <p>Although rickets <a href="https://www.nhs.uk/conditions/rickets-and-osteomalacia/#:%7E:text=The%20number%20of%20rickets%20cases,from%20sunlight%2C%20can%20develop%20rickets.">isn’t very common</a> in the UK today, it can still occur in children if they lack vitamin D. In adults, vitamin D deficiency can cause bone pain, tenderness and muscles weakness, as well as increased risk of osteomalacia – often called “soft bone disease” – which leads to weakening or softening bones.</p> <p>The reason a lack of vitamin D can have such an effect on bone health is due to the vitamin’s relationship with <a href="https://pubmed.ncbi.nlm.nih.gov/18844850/">calcium and phosphate</a>. Both of these minerals help keep our bones strong – but they require vitamin D in order to be able to reinforce and strengthen bones.</p> <h2>Other health benefits</h2> <p>In addition to its effects on the skeleton, a growing body of research is beginning to indicate that vitamin D supplements may have additional benefits to our health.</p> <p>For example, <a href="https://ar.iiarjournals.org/content/42/10/5009.long">research shows</a> there’s a link between vitamin D deficiency and increased risk of catching certain viral illnesses, including the <a href="https://pubmed.ncbi.nlm.nih.gov/19237723/">common cold</a>, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7231123/">flu</a> and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7385774/">COVID</a>.</p> <p>Similarly, several studies – <a href="https://pubmed.ncbi.nlm.nih.gov/32904944/">including my own</a> – have demonstrated in cell models that vitamin D promotes immunity against microbes, such as the bacteria which causes tuberculosis. This means vitamin D may potentially prevent some types of infections.</p> <p>Vitamin D may also dampen inflammatory immune responses, which could potentially protect against autoimmune diseases, such as <a href="https://pubmed.ncbi.nlm.nih.gov/29243029/">multiple sclerosis</a> and <a href="https://www.frontiersin.org/articles/10.3389/fmed.2020.596007/full">rheumatoid arthritis</a>.</p> <p>One 2022 trial, which looked at over 25,000 people over the age of 50, found taking a 2,000 IU (50 micrograms) vitamin D supplement each day was associated with an <a href="https://www.bmj.com/content/376/bmj-2021-066452">18% lower risk</a> of autoimmune disease – notably rheumatoid arthritis.</p> <p>Vitamin D supplements may also be linked with lower risk of cardiovascular disease. A <a href="https://www.bmj.com/content/381/bmj-2023-075230">major Australian study</a>, which looked at over 21,000 people aged 60-84, found that participants who took a 2,000 IU vitamin D supplement a day for five years had a lower risk of suffering a major cardiovascular event (such as stroke or heart attack) compared to those who didn’t take a supplement.</p> <p>It’s currently not known why vitamin D may have these benefits on these other areas of our health. It’s also worth noting that in many of these trials, very few of the participants were actually vitamin D deficient. While we might speculate the observed health benefits may be even greater in people with vitamin D deficiency, it will be important for future research to study these factors.</p> <p>While it’s too early to say whether vitamin D supplements have broad health benefits, it’s clear it’s beneficial for bone health. It may be worthwhile to take a supplement in the winter months, especially if you’re over 65, have darker skin or spent a lot of time indoors as these factors can put you at <a href="https://www.mayoclinic.org/healthy-lifestyle/nutrition-and-healthy-eating/expert-answers/vitamin-d-deficiency/faq-20058397#:%7E:text=However%2C%20some%20groups%20%E2%80%94%20particularly%20people,sun%20exposure%20or%20other%20factors.">increased risk of vitamin D deficiency</a>.</p> <p>The research also shows us that we should be rethinking vitamin D supplementation advice. While in the UK it’s recommended people get 400 IU of vitamin D a day, many trials have shown 2,000 IU a day is associated with health benefits.<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/219521/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/martin-hewison-1494746"><em>Martin Hewison</em></a><em>, Professor of Molecular Endocrinology, <a href="https://theconversation.com/institutions/university-of-birmingham-1138">University of Birmingham</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.
