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

<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> 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. 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. 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>. 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. <h2>How much is too much?</h2> 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>. 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. 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>. 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>. 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>. 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>. <h2>Why the waist?</h2> 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). 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>. 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. 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. <h2>Muscle matters</h2> 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. 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. 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. 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. 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. <h2>Getting moving is important advice</h2> 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. 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>. 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. <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" /> <a href="https://theconversation.com/profiles/rob-newton-12124">Rob Newton</a>, Professor of Exercise Medicine, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Elephant tourism often involves cruelty – here are steps toward more humane, animal-friendly excursions

<a href="https://theconversation.com/profiles/michelle-szydlowski-1495781">Michelle Szydlowski</a>, <a href="https://theconversation.com/institutions/miami-university-1934">Miami University</a> Suju Kali is a 50-year-old elephant in Nepal who has been carrying tourists for over 30 years. Like many elephants I encounter through my <a href="https://doi.org/10.1080/10888705.2022.2028628">research</a>, Suju Kali exhibits anxiety and can be aggressive toward strangers. She suffers from emotional trauma as a result of prolonged, commercial human contact. Like Suju Kali, many animals are trapped within the tourism industry. Some venues have no oversight and little concern for animal or tourist safety. Between 120,000 and 340,000 animals are used globally in a variety of wildlife tourism attractions, including <a href="https://doi.org/10.1371/journal.pone.0138939">endangered species</a> like elephants. Over a quarter of the world’s <a href="https://www.iucnredlist.org/species/7140/45818198">endangered elephants</a> reside in captivity with little oversight. Wildlife tourism – which involves viewing wildlife such as primates or birds in conservation areas, feeding or touching captive or “rehabilitated” wildlife in facilities, and bathing or riding animals like elephants – is <a href="https://doi.org/10.1080/14724049.2022.2156523">tricky business</a>. I know this because I am <a href="https://scholar.google.com/citations?user=YbweA2MAAAAJ&hl=en">a researcher studying human relationships with elephants</a> in both tourism and conservation settings within Southeast Asia. These types of experiences have long been an <a href="https://kathmandupost.com/money/2021/06/17/tourism-is-nepal-s-fourth-largest-industry-by-employment-study">extremely popular and profitable</a> part of the <a href="https://journals.plos.org/plosbiology/article?id=10.1371/journal.pbio.1002074">tourism market</a>. But now, many travel-related organizations are urging people not to participate in, or <a href="https://www.usatoday.com/story/travel/destinations/2018/04/27/animal-welfare-travelers-how-enjoy-wildlife-without-harming/544938002/">calling for an outright ban on, interactive wildlife experiences</a>. Tourism vendors have started marketing more “ethical options” for consumers. Some are attempting to truly improve the health and welfare of wildlife, and some are transitioning captive wildlife into touch-free, non-riding or lower-stress environments. In other places, organizations are attempting to <a href="https://www.fao.org/documents/card/es/c/b2c5dad0-b9b9-5a3d-a720-20bf3b9f0dc2/">implement standards of care</a> or create manuals that outline good practices for animal husbandry. This marketing, academics argue, is often simply “<a href="https://doi.org/10.1016/j.gecco.2017.11.007">greenwashing</a>,” <a href="http://dx.doi.org/10.1080/13683500.2023.2280704">applying marketing labels to make consumers feel better</a> about their choices without making any real changes. Worse, research shows that some programs marketing themselves as ethical tourism may instead be widening economic gaps and harming both humans and other species that they are meant to protect. <h2>No quick fix</h2> For example, rather than tourist dollars trickling down to local struggling families as intended by local governments, many tourism venues are owned by nonresidents, <a href="http://dx.doi.org/10.3126/japfcsc.v2i1.26746">meaning the profits do not stay in the area</a>. Likewise, only a small number of residents can afford to own tourism venues, and venues do not provide employment for locals from lower income groups. This economic gap is especially obvious in Nepalese elephant stables: Venue owners continue to make money off elephants, while elephant caregivers continue to work 17 hours a day for about US$21 a month; tourists are led to believe they are “<a href="https://www.cabidigitallibrary.org/doi/book/10.1079/9781800624498.0000">promoting sustainability</a>.” Yet, there are no easy answers, especially for elephants working in tourism. Moving them to sanctuaries is difficult because with no governmental or global welfare oversight, elephants may end up in worse conditions. Many kindhearted souls who want to “help” elephants know little about their biology and mental health needs, or what it takes to keep them healthy. Also, feeding large animals like Suju Kali is pricey, <a href="https://doi.org/10.3390/ani14010171">costing around $19,000 yearly</a>. So without profits from riding or other income, owners – or would-be rescuers – can’t maintain elephants. Releasing captive elephants to the jungle is not a choice – many have never learned to live in the wild, so they cannot survive on their own. <h2>Hurting local people</h2> Part of the problem lies with governments, as many have marketed tourism as a way to fund conservation projects. For example in Nepal, a percentage of ticket sales from elephant rides are given to community groups to use for forest preservation and support for local families. Increasing demand for <a href="https://www.routledge.com/Tourism-and-Animal-Ethics/Fennell/p/book/9781032431826">wildlife-based tourism</a> may increase traffic in the area and thus put pressure on local governments to further limit local people’s access to forest resources. This may also lead to <a href="https://www.worldanimalprotection.org/latest/news/un-world-tourism-organisation-urged-create-better-future-animals/">increased demands on local communities</a>, as was the case in Nepal. In the 1970s, the Nepalese government removed local people from their lands in what is now Chitwan National Park as part of increasing “conservation efforts” and changed the protected area’s boundaries. Indigenous “Tharu,” or people of the forest, were forced to abandon their villages and land. While some were offered access to “buffer zones” in the 1990s, many remain poor and landless today. In addition, more and more desirable land surrounding conservation areas in Nepal is being developed for tourist-based businesses such as hotels, restaurants and shops, <a href="http://dx.doi.org/10.3126/japfcsc.v2i1.26746">pushing local poor people farther away</a> from central village areas and the associated tourism income. Some activists would like humans to simply release all wildlife back into the wild, but <a href="https://www.cabidigitallibrary.org/doi/book/10.1079/9781800624498.0000">there are multiple issues</a> with that. Elephant habitats throughout Southeast Asia have been transformed into croplands, cities or train tracks for human use. Other problems arise from the fact that tourism elephants have <a href="https://doi.org/10.4324/9781315457413">never learned</a> how to be elephants in their natural elements, as they were <a href="https://www.pugetsound.edu/sites/default/files/file/8342_Journal%20of%20Tourism%20%282009%29_0.pdf">separated from their herds</a> at an early age. So tourism may be vital to providing food, care and shelter to captive elephants for the rest of their lives and providing jobs for those who really need them. Because elephants can live beyond 60 years, this can be a large commitment. <h2>How to be an ethical tourist</h2> To protect elephants, tourists should check out reviews and photos from any venue they want to visit, and look for clues that animal welfare might be impacted, such as tourists allowed to feed, hold or ride captive wildlife animals. Look for healthy animals, which means doing research on what “healthy” animals of that species should look like. If a venue lists no-touch demonstrations – “unnatural” behaviors that don’t mimic what an elephant might do of their own accord, such as sitting on a ball or riding a bike, or other performances – remember that the behind-the-scenes training used to achieve these behaviors can be <a href="https://doi.org/10.21832/9781845415051-014">violent, traumatic or coercive</a>. Another way to help people and elephant is to to use small, local companies to book your adventures in your area of interest, rather than paying large, international tourism agencies. Look for locally owned hotels, and wait to book excursions until you arrive so you can use local service providers. Book homestay programs and attend cultural events led by community members; talk to tourists and locals you meet in the target town to get their opinions, and use local guides who provide wildlife viewing opportunities <a href="https://nepaldynamicecotours.com/">while maintaining distance from animals</a>. Or tourists can ask to visit <a href="https://www.americanhumane.org/press-release/global-humane-launches-humane-tourism-certification-program/">venues that are certified</a> by international humane animal organizations and that <a href="https://www.su4e.org/">do not allow contact</a> with wildlife. Or they can opt for guided hikes, canoe or kayak experiences, and other environmentally friendly options. While these suggestions will not guarantee that your excursion is animal-friendly, they will help decrease your impact on wildlife, support local families and encourage venues to stop using elephants as entertainment. Those are good first steps.<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/219792/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/michelle-szydlowski-1495781">Michelle Szydlowski</a>, Visiting Assistant Professor, Department of Biology, Project Dragonfly, <a href="https://theconversation.com/institutions/miami-university-1934">Miami University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Travel Tips

Do optimists really live longer? Here’s what the research says

<a href="https://theconversation.com/profiles/fuschia-sirois-331254">Fuschia Sirois</a>, <a href="https://theconversation.com/institutions/durham-university-867">Durham University</a> Do you tend to see the glass as half full, rather than half empty? Are you always looking on the bright side of life? If so, you may be surprised to learn that this tendency could actually be good for your health. A <a href="https://content.apa.org/record/2020-71981-001">number of studies</a> have shown that optimists enjoy higher levels of wellbeing, better sleep, lower stress and even better cardiovascular health and immune function. And now, <a href="https://pubmed.ncbi.nlm.nih.gov/35674052/">a recent study</a> has shown that being an optimist is linked to longer life. To conduct their study, researchers tracked the lifespan of nearly 160,000 women aged between 50 to 79 for a period of 26 years. At the beginning of the study, the women completed a <a href="https://local.psy.miami.edu/people/faculty/ccarver/availbale-self-report-instruments/lot-r/">self-report measure of optimism</a>. Women with the highest scores on the measure were categorised as optimists. Those with the lowest scores were considered pessimists. Then, in 2019, the researchers followed up with the participants who were still living. They also looked at the lifespan of participants who had died. What they found was that those who had the highest levels of optimism were more likely to live longer. More importantly, the optimists were also more likely than those who were pessimists to live into their nineties. Researchers refer to this as “exceptional longevity”, considering the average lifespan for women is about 83 years in developed countries. What makes these findings especially impressive is that the results remained even after accounting for other factors known to predict a long life – including education level and economic status, ethnicity, and whether a person suffered from depression or other chronic health conditions. But given this study only looked at women, it’s uncertain whether the same would be true for men. However, <a href="https://www.pnas.org/doi/abs/10.1073/pnas.1900712116">another study</a> which looked at both men and women also found that people with the highest levels of optimism enjoyed a lifespan that was between 11% and 15% longer than those who were the least optimistic. <h2>The fountain of youth?</h2> So why is it that optimists live longer? At first glance it would seem that it may have to do with their healthier lifestyle. For example, <a href="https://www.ahajournals.org/doi/10.1161/CIRCRESAHA.117.310828">research from several studies</a> has found that optimism is linked to eating a healthy diet, staying physically active, and being less likely to smoke cigarettes. These healthy behaviours are well known to improve heart health and <a href="https://www.who.int/news-room/fact-sheets/detail/noncommunicable-diseases">reduce the risk</a> for cardiovascular disease, which is a <a href="https://www.who.int/news-room/fact-sheets/detail/cardiovascular-diseases-(cvds)">leading cause of death</a> globally. Adopting a healthy lifestyle is also <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3857242/">important for reducing the risk</a> of other potentially deadly diseases, such as diabetes and cancer. But having a healthy lifestyle may only be part of the reason optimists live a longer than average life. This latest study found that lifestyle only accounted for 24% of the link between optimism and longevity. This suggests a number of other factors affect longevity for optimists. Another possible reason could be due to the way optimists manage stress. When faced with a stressful situation, optimists tend to deal with it head-on. They <a href="https://pubmed.ncbi.nlm.nih.gov/16859439/">use adaptive coping strategies</a> that help them resolve the source of the stress, or view the situation in a less stressful way. For example, optimists will problem-solve and plan ways to deal with the stressor, call on others for support, or try to find a “silver lining” in the stressful situation. All of these approaches are well-known to reduce feelings of stress, as well as the biological reactions that occur when we feel stressed. It’s these <a href="https://www.apa.org/topics/stress/body">biological reactions to stress</a> –- such as elevated cortisol (sometimes called the “stress hormone”), increased heart rate and blood pressure, and impaired immune system functioning –- that can take a toll on health over time and increase the risk for developing <a href="https://www.sciencedirect.com/science/article/pii/S0889159115004316?via%3Dihub">life-threatening diseases</a>, such as cardiovascular disease. In short, the way optimists cope with stress may help protect them somewhat against its harmful effects. <h2>Looking on the bright side</h2> Optimism is typically viewed by researchers as a relatively stable personality trait that is determined by both <a href="https://www.cambridge.org/core/journals/twin-research-and-human-genetics/article/sex-differences-in-the-genetic-architecture-of-optimism-and-health-and-their-interrelation-a-study-of-australian-and-swedish-twins/58F21AA11943D44B4BA4C63A966E6AC7">genetic</a> and early childhood influences (such as having a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6541423/">secure and warm relationship</a> with your parents or caregivers). But if you’re not naturally prone to seeing the glass as half full, there are some ways you can increase your <a href="https://www.tandfonline.com/doi/abs/10.1080/17439760.2016.1221122?journalCode=rpos20">capacity to be optimistic</a>. Research shows optimism can change over time, and can be cultivated by engaging in simple exercises. For example, visualising and then writing about your “<a href="https://www.psychologytoday.com/us/blog/what-matters-most/201303/what-is-your-best-possible-self">best possible self</a>” (a future version of yourself who has accomplished your goals) is a technique that studies have found can <a href="https://www.tandfonline.com/doi/full/10.1080/17439760.2016.1221122">significantly increase optimism</a>, at least temporarily. But for best results, the goals need to be both positive and reasonable, rather than just wishful thinking. Similarly, simply <a href="https://www.tandfonline.com/doi/abs/10.3200/SOCP.149.3.349-364">thinking about positive future events</a> can also be effective for boosting optimism. It’s also crucial to temper any expectations for success with an accurate view of what you can and can’t control. Optimism is reinforced when we experience the positive outcomes that we expect, and <a href="https://psycnet.apa.org/record/1970-20680-001">can decrease</a> when these outcomes aren’t as we want them to be. Although more research is needed, it’s possible that regularly envisioning yourself as having the best possible outcomes, and taking realistic steps towards achieving them, can help develop an optimistic mindset. Of course, this might be easier said than done for some. If you’re someone who isn’t naturally optimistic, the best chances to improve your longevity is by <a href="https://journals.plos.org/plosmedicine/article?id=10.1371/journal.pmed.1003332">living a healthy lifestyle</a> by staying physically active, eating a healthy diet, managing stress, and getting a good night’s sleep. Add to this cultivating a more optimistic mindset and you might further increase your chances for a long life.<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/184785/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/fuschia-sirois-331254">Fuschia Sirois</a>, Professor in Social & Health Psychology, <a href="https://theconversation.com/institutions/durham-university-867">Durham University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Hospice nurse explains why we shouldn't be afraid to die

A hospice nurse has shared why we shouldn't be afraid to die, explaining all the ways in which our bodies "shut off" to make for a "peaceful" death. Julie McFadden, a nurse based in Los Angeles, has long been sharing videos and explanations about end of life care in an attempt to destigmatise the conversations and fear around death and dying. In her latest YouTube video, McFadden got candid with her followers as she confessed she isn't afraid to die and why no one else should be either. She went on to explain all the ways in which our bodies are supposed to "shut off" in our final moments, making for a "peaceful" and "natural" death. " "I'm not afraid of death and here's the science behind it, our body biologically helps us die, so here is what I've seen and learned as a hospice nurse over the years - our body is literally built to die," she said. The hospice nurse revealed that bodies began to slowly shut down in the six months leading up to death, explaining that a person nearing the end of their life would start "eating less, drinking less, and sleeping more." "Why is that happening? Because calcium levels in the body are going up and because calcium levels are going up the person is getting sleepier," Julie said. "Our brains have built in mechanisms to make us hungry and thirsty. Biologically, when the body knows it's getting towards the end of life those mechanisms shut off, so the person does not usually feel hungry and does not usually feel thirsty, which is helping the body slowly shut down." <iframe title="YouTube video player" src="https://www.youtube.com/embed/CJEkzA0gt6s?si=CIzcf3xchddKtf1D" width="560" height="315" frameborder="0" allowfullscreen="allowfullscreen"></iframe> She put minds at ease by debunking a common concern, saying that while certain diseases could make death more uncomfortable, dying in itself wasn't painful. "There are times when the disease that the person is experiencing can cause symptoms and it's more difficult because they're dying from a certain disease, but the actual process that the body is going through to help it die is actually helping that person," Julie added. "There have been many times as a hospice nurse that I have watched someone slowly die on hospice and I have not needed to give them any medication because their disease was not causing any symptoms - no pain, no shortness of breath, they were just more tired and weren't eating or drinking." "They still did all of the things any other person on hospice would be doing, like they slowly go unconscious, they slowly stop eating and drinking. I didn't have to give them any medications. They were perfectly comfortable and died a very peaceful death." Julie explained that death was even "comforting" in a way because when you're about to take your last breath, your body released endorphins, making you feel euphoric in your final moments. "The body slowly goes into something called ketosis, which releases endorphins. In that person's body those endorphins dull pain, dull nerves, and they also give that person a euphoric sense, so they feel good," she said. "There are many reasons why I don't fear death. Yes, I have had some pretty crazy spiritual experiences as a hospice nurse that led me to not fear death, but there are also biological, metabolical, and physiological things that happen in the body that truly, truly comforted me." She concluded, "Our bodies are built to die. The less we mess with that, the more peaceful it will be." Image credits: YouTube / Instagram

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

<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> 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. Silent cancers are those without noticeable symptoms. They pose a unique challenge in early detection and treatment. 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>. 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. 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. <h2>The importance of early diagnosis</h2> Whatever the cancer, it’s always important to get an early diagnosis though – and for silent cancers, this is obviously a challenge. 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. <figure><iframe src="https://www.youtube.com/embed/MGMy6BzBvp0?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> 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. 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. 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. 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>. <figure><iframe src="https://www.youtube.com/embed/nA9_Io3LDpA?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> 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. <h2>Biomarker discovery</h2> 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. 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. 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.<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/226536/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/justin-stebbing-1405462">Justin Stebbing</a>, Professor of Biomedical Sciences, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Considering taking a weight-loss drug like Ozempic? Here are some potential risks and benefits

<a href="https://theconversation.com/profiles/lauren-ball-14718">Lauren Ball</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> and <a href="https://theconversation.com/profiles/emily-burch-438717">Emily Burch</a>, <a href="https://theconversation.com/institutions/southern-cross-university-1160">Southern Cross University</a> After weight-loss drugs like Ozempic exploded onto the market, celebrities and social media influencers were quick to spruik their benefits, leading to their rapid rise in use. In the last three months of 2022, clinicians in the United States alone wrote <a href="https://www.washingtonpost.com/business/2023/09/27/ozempic-prescriptions-data-analysis/">more than nine million prescriptions</a> for these drugs. As they’ve grown in popularity, we’ve also heard more about the potential side effects – from common gastrointestinal discomforts, to more serious mental health concerns. But what does the science say about how well Ozempic and Wegovy (which are both brand names of the drug semaglutide) work for weight loss? And what are the potential side effects? Here’s what to consider if you or a loved one are thinking of taking the drug. <h2>Potential benefits</h2> 1) It’s likely to help you lose weight The largest, well-conducted <a href="https://pubmed.ncbi.nlm.nih.gov/33567185/">research study</a> of semaglutide was from United Kingdom in 2021. Some 1,961 people who were classified as “overweight” or “obese” were randomly assigned to have either semaglutide or a placebo and followed for 68 weeks (about 1.3 years). All participants also had free access to advice about healthy eating and physical activity. The study found those taking semaglutide lost weight – significantly more than people who had the placebo (-14.9% of their body weight compared with -2.4% of body weight). In another <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9486455/">study</a> in the United States, one health-care clinic gave 408 people weekly injections of semaglutide. Over the first three months, those included in the final analysis (175 people) lost an average of 6.7kg. Over the first six months, they lost an average of 12.3kg. Large weight losses have been found in a more <a href="https://www.nature.com/articles/s41591-022-02026-4">recent trial</a> of semaglutide, suggesting weight loss is a very likely outcome of ongoing use of the medication. 2) It may reduce your chronic disease risk factors When people in the overweight or obese weight categories lose <a href="https://www.sciencedirect.com/science/article/pii/S1550413116300535">at least 5%</a> of their body weight, physiological changes often occur beyond a change in weight or shape. This <a href="https://www.nih.gov/news-events/nih-research-matters/research-context-obesity-metabolic-health">might include</a> lowered cholesterol levels, lowered blood pressure and lowered blood glucose levels, which all reduce the risk of chronic diseases. In one of the semaglutide <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9486455/">trials</a>, most people (87.3%) lost at least 5% of their body weight. Although most of the large studies of semaglutide excluded people with metabolic health conditions such as type 2 diabetes, metabolic health gains were <a href="https://pubmed.ncbi.nlm.nih.gov/33567185/">observed</a>, including lowered blood pressure, blood glucose levels and fasting blood lipid (fat) levels. In the UK <a href="https://pubmed.ncbi.nlm.nih.gov/33567185/">study</a> from 2021, people taking semaglutide had greater improvements in physical capabilities and risk factors for heart disease and diabetes, including reductions in waist circumference, markers of inflammation, blood pressure and blood glucose levels. 3) It might improve your quality of life, emotional wellbeing or sense of achievement The original trial of semaglutide did not focus on this bundle of benefits, but further follow-ups show additional benefits associated with the medication. Compared to the placebo, people taking semaglutide saw significant <a href="https://www.tandfonline.com/doi/full/10.1080/00325481.2022.2150006">improvements</a> in their physical functioning and perceptions of their general health, social functioning and mental health. Anecdotally (not based on scientific research), people using semaglutide, such as <a href="https://people.com/oprah-winfrey-reveals-weight-loss-medication-exclusive-8414552">Oprah Winfrey</a>, report a reclaiming or turning point of their life, social situation and body image. <h2>What about the risks?</h2> 1) You may experience gastrointestinal symptoms In the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9486455/">US clinical trial</a>, nearly half (48.6%) of people taking semaglutide reported experiencing adverse effects. Nausea and vomiting were the most frequently experienced (36.6%) followed by diarrhea (8.6%), fatigue (6.3%) and constipation (5.7%). In the UK study, nausea and diarrhoea were also commonly reported. In <a href="https://www.nejm.org/doi/10.1056/NEJMoa2032183?url_ver=Z39.88-2003&rfr_id=ori:rid:crossref.org&rfr_dat=cr_pub%20%200pubmed">another trial</a>, many participants (74.2%) using semaglutide reported gastrointestinal symptoms. However, nearly half (47.9%) using the placebo also reported gastrointestinal symptoms, indicating that symptoms may be similar to those experienced during normal daily living. Most gastrointestinal symptoms were mild to moderate in severity, and resolved for most people without the need to stop participating in the study. 2) You might feel fatigued Fatigue was the second most common side effect for participants in the US <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9486455/">clinical trial</a>, affecting 6.3% of participants. 3) You might be among the minority who don’t tolerate the drug Australia’s Therapeutic Goods Administration (TGA) has <a href="https://www.tga.gov.au/news/safety-alerts/compounding-safety-information-semaglutide-products">approved</a> Ozempic as safe to use, for the treatment of type 2 diabetes but it has not yet been approved for weight loss. The TGA has also <a href="https://www.tga.gov.au/resources/prescription-medicines-registrations/wegovy-novo-nordisk-pharmaceuticals-pty-ltd">approved Wegovy</a> (a higher dose of semagtlutide) for weight loss, however it’s not yet available in Australia. In the US <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9486455/">clinical trial</a>, no unexpected safety issues were reported. However, five patients (2.9%) had to stop taking the medication because they could not tolerate the adverse effects. Fifteen (8.6%) had to either reduce the dose or remain on the same dose to avoid the adverse effects. In <a href="https://www.nejm.org/doi/10.1056/NEJMoa2032183?url_ver=Z39.88-2003&rfr_id=ori:rid:crossref.org&rfr_dat=cr_pub%20%200pubmed">other studies</a>, some patients stopped the trial due to gastrointestinal symptoms being so severe they could not tolerate continuing. More severe safety concerns reported in <a href="https://www.nejm.org/doi/10.1056/NEJMoa2032183?url_ver=Z39.88-2003&rfr_id=ori:rid:crossref.org&rfr_dat=cr_pub%20%200pubmed">studies</a> include gallbladder-related disorders (mostly cholelithiasis, also known as gallstones) in 34 patients (2.6%) and mild acute pancreatitis in three patients (0.2%). All people recovered during the trial period. A 2024 European <a href="https://link.springer.com/article/10.1007/s11096-023-01694-7">study</a> analysed psychiatric adverse events associated with semaglutide, liraglutide and tirzepatide (which work in a similar way to semaglutide). Between January 2021 and May 2023, the drug database recorded 481 psychiatric events (about 1.2% of the total reported) associated with these drugs. About half of these events were reported as depression, followed by anxiety (39%) and suicidal ideation (19.6%). Nine deaths and 11 life-threatening outcomes were reported during the study period. Due to the severity and fatal outcomes of some of these reports, <a href="https://www.fda.gov/drugs/drug-safety-and-availability/update-fdas-ongoing-evaluation-reports-suicidal-thoughts-or-actions-patients-taking-certain-type">the US Food and Drug Administration</a> investigated further but did not find evidence that use of these medicines caused suicidal thoughts or actions. 4) It might be difficult to access Despite being considered safe, the TGA has <a href="https://www.tga.gov.au/safety/shortages/medicine-shortage-alerts/update-prescribers-advised-not-start-new-patients-ozempic#:%7E:text=Ozempic%27s%20TGA%2Dapproved%20indication%20is,consult%20the%20appropriate%20prescribing%20guidelines.">warned</a> significant Ozempic access barriers are likely to continue throughout 2024. To manage the shortage, pharmacists are instructed to give preference to people with type 2 diabetes who are seeking the medication. 5) You might not always get clear information from vested interests Given the popularity of Ozempic and Wegovy, health organisations such as the World Obesity Federation have expressed <a href="https://www.theguardian.com/society/2023/mar/12/orchestrated-pr-campaign-how-skinny-jab-drug-firm-sought-to-shape-obesity-debate">concern</a> about the medication’s marketing, PR and strong <a href="https://www.theguardian.com/australia-news/2023/jan/06/tga-investigates-influencers-after-diabetes-drug-ozempic-promoted-as-weight-loss-treatment">social media presence</a>. Some journalists have <a href="https://www.theguardian.com/society/2023/mar/12/orchestrated-pr-campaign-how-skinny-jab-drug-firm-sought-to-shape-obesity-debate">raised conflict of interest concerns</a> about the relationship between some obesity researchers and Novo Nordrisk, Ozempic and Wegovy’s manufacturer. The worry is that researchers might be influenced by their relationship with Novo Nordrisk to produce study results that are more favourable to the medications. <h2>Bottom line</h2> Ozempic is a medication that should be used in conjunction with your health care provider. But remember, weight is only one aspect of your health and wellbeing. It’s important to take a holistic view of your health and prioritise eating well, moving more and getting enough sleep. <hr /> Read the other articles in The Conversation’s <a href="https://theconversation.com/au/topics/ozempic-132745">Ozempic series</a> here.<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/219312/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/lauren-ball-14718">Lauren Ball</a>, Professor of Community Health and Wellbeing, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> and <a href="https://theconversation.com/profiles/emily-burch-438717">Emily Burch</a>, Lecturer, <a href="https://theconversation.com/institutions/southern-cross-university-1160">Southern Cross University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Eating some chocolate really might be good for you – here’s what the research says

<a href="https://theconversation.com/profiles/dan-baumgardt-1451396">Dan Baumgardt</a>, <a href="https://theconversation.com/institutions/university-of-bristol-1211">University of Bristol</a> Although it always makes me scoff slightly to see Easter eggs making their first appearance in supermarkets at the end of December, there are few people who aren’t delighted to receive a bit of chocolate every year. It makes sense that too much chocolate would be bad for you because of the high fat and sugar content in most products. But what should we make of common claims that eating some chocolate is actually good for you? Happily, there is a fair amount of evidence that shows, in the right circumstances, chocolate may be both beneficial for your heart and good for your mental state. In fact, chocolate – or more specifically cacao, the raw, unrefined bean – is a medicinal wonder. It contains many different active compounds which can evoke pharmacological effects within the body, like medicines or drugs. Compounds that lead to neurological effects in the brain have to be able to cross the <a href="https://link.springer.com/chapter/10.1007/978-3-642-13443-2_7">blood-brain barrier</a>, the protective shield which prevents harmful substances – like toxins and bacteria – entering the delicate nervous tissue. One of these is the compound <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3672386/">theobromine</a>, which is also found in tea and contributes towards its bitter taste. Tea and chocolate also contain caffeine, which theobromine is related to as part of the purine family of chemicals. These chemicals, among others, contribute to chocolate’s addictive nature. They have the ability to cross the blood-brain barrier, where they can influence the nervous system. They are therefore known as <a href="https://pubmed.ncbi.nlm.nih.gov/15549276/">psychoactive</a> chemicals. <figure><iframe src="https://www.youtube.com/embed/HloqayQdR6M?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> What effects can chocolate have on mood? Well, <a href="https://academic.oup.com/nutritionreviews/article/71/10/665/1931144?login=false">a systematic review</a> looked at a group of studies which examined the feelings and emotions associated with consuming chocolate. Most demonstrated improvements in mood, anxiety, energy and states of arousal. Some noted the feeling of guilt, which is perhaps something we’ve all felt after one too many Dairy Milks. <h2>Health benefits of cocoa</h2> There are other organs, aside from the brain, that might benefit from the medicinal effects of cocoa. For centuries, chocolate has been used as a medicine to treat a <a href="https://pubmed.ncbi.nlm.nih.gov/10917925/">long list of diseases</a> including anaemia, tuberculosis, gout and even low libido. These might be spurious claims but there is evidence to suggest that eating cacao has a positive effect on the cardiovascular system. First, it can prevent <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8068178/">endothelial dysfunction</a>. This is the process through which arteries harden and get laden down with fatty plaques, which can in turn lead to heart attacks and strokes. Eating dark chocolate may also reduce <a href="https://www.sciencedirect.com/science/article/pii/S1537189115001135?via%3Dihub">blood pressure</a>, which is another risk factor for developing arterial disease, and prevent formation of clots which block up blood vessels. <figure><iframe src="https://www.youtube.com/embed/8VUcPCbSSCY?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> Some studies have suggested that dark chocolate might be useful in adjusting ratios of <a href="https://pubmed.ncbi.nlm.nih.gov/20968113/">high-density lipoprotein cholesterol</a>, which can help protect the heart. Others have examined insulin resistance, the phenomenon associated with Type 2 diabetes and weight gain. They suggest that the <a href="https://www.sciencedirect.com/science/article/pii/S0963996900000697#:%7E:text=Cocoa%20is%20rich%20in%20polyphenols%20particularly%20in%20catechins,and%20cocoa%20powder%20have%20been%20published%20only%20recently.">polyphenols</a> – chemical compounds present in plants – found in foodstuffs like chocolate may also lead to <a href="https://pubmed.ncbi.nlm.nih.gov/29993262/">improved control of blood sugars</a>. <h2>Chocolate toxicity</h2> As much as chocolate might be considered a medicine for some, it can be a poison for others. It’s well documented that the ingestion of caffeine and theobromine is highly toxic for domestic animals. Dogs are <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4801869/">particularly affected</a> because of their often voracious appetites and generally unfussy natures. The culprit is often dark chocolate, which can provoke symptoms of agitation, rigid muscles and even seizures. In certain cases, if ingested in high enough quantities, it can lead to comas and abnormal, even fatal heart rhythms. Some of the compounds found in chocolate have also been found to have potentially negative effects in humans. Chocolate is a source of oxalate which, along with calcium, is one of the main components of <a href="https://pubmed.ncbi.nlm.nih.gov/20301742/">kidney stones</a>. Some clinical groups have advised against consuming oxalate rich foods, such as spinach and rhubarb – and chocolate, for those who suffer from recurrent kidney stones. So, what should all this mean for our chocolate consumption habits? Science points in the direction of chocolate that has as high a cocoa solid content as possible, and the minimum of extras. The potentially harmful effects of chocolate are more related to fat and sugar, and may counteract any possible benefits. A daily dose of 20g-30g of plain or dark chocolate with cocoa solids above 70% – rather than milk chocolate, which contains fewer solids and white chocolate, which contains none – could lead to a greater health benefit, as well as a greater high. But whatever chocolate you go for, please don’t share it with the dog.<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/226759/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/dan-baumgardt-1451396">Dan Baumgardt</a>, Senior Lecturer, School of Physiology, Pharmacology and Neuroscience, <a href="https://theconversation.com/institutions/university-of-bristol-1211">University of Bristol</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Here’s why having chocolate can make you feel great or a bit sick – plus 4 tips for better eating

<a href="https://theconversation.com/profiles/saman-khalesi-366871">Saman Khalesi</a>, <a href="https://theconversation.com/institutions/cquniversity-australia-2140">CQUniversity Australia</a> Australians are <a href="https://www.retail.org.au/media/sweet-spending-boon-predicted-for-easter-retail">predicted</a> to spend around A$1.7 billion on chocolates, hot cross buns and other special foods this Easter season. Chocolate has a long history of production and consumption. It is made from cacao beans that go through processes including fermentation, drying, roasting and grounding. What is left is a rich and fatty liquor that is pressed to remove the fat (cocoa butter) and the cacao (or “cocoa”) powder which will then be mixed with different ingredients to produce dark, milk, white and other types of chocolates. There are several health benefits and potential problems that come in these sweet chocolatey packages. <h2>The good news</h2> Cacao beans contain <a href="https://foodstruct.com/food/cocoa-bean">minerals</a> like iron, potassium, magnesium, zinc and phosphorus and some vitamins. They are also rich in beneficial chemicals called <a href="https://pubmed.ncbi.nlm.nih.gov/23150750/">polyphenols</a>. These are great antioxidants, with the potential to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5465250/">improve heart health</a>, increase <a href="https://pubmed.ncbi.nlm.nih.gov/25164923/">nitric oxide</a> (which dilates blood vessels) and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3488419/">reduce blood pressure</a>, provide food for gut microbiota and <a href="https://www.mdpi.com/2072-6643/12/7/1908">promote gut health</a>, boost the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5465250/">immune system</a> and reduce inflammation. However, the concentration of polyphenols in the chocolate we eat depends largely on the cocoa solid amounts used in the final product. In general terms, the darker the chocolate, the more cocoa solids, minerals and polyphenols it has. For example, dark chocolates may have around <a href="https://www.tandfonline.com/doi/full/10.1080/10942912.2011.614984">seven times more polyphenols</a> compared to white chocolates and <a href="https://www.tandfonline.com/doi/full/10.1080/10942912.2011.614984">three times more polyphenols</a> compared to milk chocolates. <h2>But also some bad news</h2> Unfortunately, the <a href="https://theconversation.com/treat-or-treatment-chocolate-is-good-but-cocoa-is-better-for-your-heart-3084">health benefits of cocoa solids</a> are easily offset by the high sugar and fat content of modern-day chocolates. For example, milk and white chocolate eggs are on average 50% sugar, 40% fat (mostly saturated fats) – which means a lot of added kilojoules (calories). Also, there may be some side effects that come with ingesting chocolate. Cocoa beans include a compound called theobromine. While it has the anti-inflammatory properties responsible for some of the health benefits of chocolate, it is also a mild brain stimulant that acts in a similar way to caffeine. The mood boost it offers may also be partly responsible for how much we <a href="https://www.frontiersin.org/articles/10.3389/fphar.2015.00030/full?crsi=662496658&cicada_org_src=healthwebmagazine.com&cicada_org_mdm=direct">like chocolate</a>. Dark chocolate has higher theobromine compared to milk and white chocolate. But accordingly, overindulging in chocolate (and therefore theobromine) may lead to feeling restless, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3672386/">headaches</a> and nausea. <h2>What else is in your chocolate?</h2> Milk and dairy-based chocolates may also cause stomach upset, abdominal pain and bloating in people with <a href="https://dietitiansaustralia.org.au/health-advice/lactose-intolerance">lactose intolerance</a>. This happens when we don’t produce enough lactase enzymes to digest milk sugar (lactose). People with lactose intolerance can usually tolerate up to 6 grams of lactose without showing symptoms. Milk chocolate can have around <a href="https://www.ncbi.nlm.nih.gov/books/NBK310258/">3 grams of lactose</a> per 40 grams (the size of a standard chocolate bar). So two chocolate bars (or the equivalent in milk chocolate eggs or bunnies) may be enough to cause symptoms. It’s worth noting that lactase enzyme activity dramatically declines as we age, with the highest activity in newborns and children. So lactose sensitivity or intolerance may not be such an issue for your kids and your symptoms may increase over time. Genetics also plays a major role in how sensitive people are to lactose. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6815241/">Allergic reactions</a> to chocolate are usually due to the added ingredients or cross-contamination with potential allergens such as nuts, milk, soy, and some sweeteners used in the production of chocolate. Symptoms can be mild (acne, rashes and stomach pain) or more severe (swelling of the throat and tongue and shortness of breath). If you or your family members have known allergic reactions, make sure you read the label before indulging – especially in a whole block or basket of the stuff. And if you or your family members do experience symptoms of an allergic reaction after eating chocolate, <a href="https://www.betterhealth.vic.gov.au/health/conditionsandtreatments/allergic-reactions-emergency-first-aid">seek medical attention</a> immediately. <h2>4 take home tips</h2> So, if you are like me and have a weakness for chocolate there are a few things you can do to make the experience a good one.<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/202848/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <ol> <li>keep an eye out for the darker chocolate varieties with higher cocoa solids. You may notice a percentage on labelling, which refers to how much of its weight is from cocoa beans. In general, the higher this percentage, the lower the sugar. White chocolate has almost no cocoa solid, and mostly cocoa butter, sugar and other ingredients. Dark chocolate has 50–100% cocoa beans, and less sugar. Aim for at least 70% cocoa</li> <li>read the fine print for additives and possible cross-contamination, especially if allergies might be an issue</li> <li>the ingredients list and nutrition information panel should tell you all about the chocolate you choosing. Go for varieties with lower sugar and less saturated fat. Nuts, seeds and dried fruits are better ingredients to have in your chocolate than sugar, creme, syrup, and caramel</li> <li>finally, treat yourself – but keep the amount you have within sensible limits!</li> </ol> <a href="https://theconversation.com/profiles/saman-khalesi-366871">Saman Khalesi</a>, Postdoctoral Fellow of the National Heart Foundation & Senior Lecturer and Discipline Lead in Nutrition, School of Health, Medical and Applied Sciences, <a href="https://theconversation.com/institutions/cquniversity-australia-2140">CQUniversity Australia</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Only walking for exercise? Here’s how to get the most out of it

<a href="https://theconversation.com/profiles/ken-nosaka-169021">Ken Nosaka</a>, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a> We’re living longer than in previous generations, with <a href="https://www.aihw.gov.au/reports/older-people/older-australians/contents/demographic-profile">one in eight</a> elderly Australians now aged over 85. But the current <a href="https://pubmed.ncbi.nlm.nih.gov/26561272/">gap</a> between life expectancy (“lifespan”) and health-adjusted life expectancy (“healthspan”) is about ten years. This means many of us live with significant health problems in our later years. To increase our healthspan, we need planned, structured and regular physical activity (or exercise). The <a href="https://www.who.int/news-room/fact-sheets/detail/physical-activity">World Health Organization recommends</a> 150–300 minutes of moderate-intensity exercise – such as brisk walking, cycling and swimming – per week and muscle strengthening twice a week. Yet few of us meet these recommendations. <a href="https://doi.org/10.1186/s12966-019-0797-2">Only 10%</a> meet the strength-training recommendations. <a href="https://pubmed.ncbi.nlm.nih.gov/32488898/">Lack of time</a> is one of the most common reasons. Walking is cost-effective, doesn’t require any special equipment or training, and can be done with small pockets of time. <a href="https://link.springer.com/epdf/10.1007/s00421-024-05453-y?sharing_token=1vDsDJTN5WzPxi5YmSEkOfe4RwlQNchNByi7wbcMAY5hnPeFvF3FY4v2z1P9M2M0oiR78kXv1Yzj0ODMgckqhKOGHUABEd9UOPOfV5kPAj1jf1IYMIYkdIBv-DUEcKCOiDdNyj6MFypeDhSyeYQrWu_bvlAYtPUmOSaldFpmycA%3D">Our preliminary research</a>, published this week, shows there are ways to incorporate strength-training components into walking to improve your muscle strength and balance. <h2>Why walking isn’t usually enough</h2> Regular walking <a href="http://theconversation.com/health-check-in-terms-of-exercise-is-walking-enough-78604">does not appear</a> to work as muscle-strengthening exercise. In contrast, exercises consisting of “eccentric” or muscle-lengthening contractions <a href="http://theconversation.com/its-ok-to-aim%20lower-with-your-new-years-exercise-resolutions-a-few-minutes-a-day-can-improve-your-muscle-strength-193713">improve</a> muscle strength, <a href="https://pubmed.ncbi.nlm.nih.gov/31130877/">prevent muscle wasting</a> and improve other functions such as balance and flexibility. Typical eccentric contractions are seen, for example, when we sit on a chair slowly. The front thigh muscles lengthen with force generation. <h2>Our research</h2> Our <a href="https://pubmed.ncbi.nlm.nih.gov/31055678/">previous research</a> found body-weight-based eccentric exercise training, such as sitting down on a chair slowly, improved lower limb muscle strength and balance in healthy older adults. We also <a href="https://pubmed.ncbi.nlm.nih.gov/28291022/">showed</a> walking down stairs, with the front thigh muscles undergoing eccentric contractions, increased leg muscle strength and balance in older women more than walking up stairs. When climbing stairs, the front thigh muscles undergo “concentric” contractions, with the muscles shortening. It can be difficult to find stairs or slopes suitable for eccentric exercises. But if they could be incorporated into daily walking, lower limb muscle strength and balance function could be improved. This is where the idea of “eccentric walking” comes into play. This means inserting lunges in conventional walking, in addition to downstairs and downhill walking. <figure><iframe src="https://www.youtube.com/embed/wAI7z3XdY9o?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>Eccentric walking means incorporating deep lunges into your movement.</figcaption></figure> In our <a href="https://link.springer.com/epdf/10.1007/s00421-024-05453-y?sharing_token=1vDsDJTN5WzPxi5YmSEkOfe4RwlQNchNByi7wbcMAY5hnPeFvF3FY4v2z1P9M2M0oiR78kXv1Yzj0ODMgckqhKOGHUABEd9UOPOfV5kPAj1jf1IYMIYkdIBv-DUEcKCOiDdNyj6MFypeDhSyeYQrWu_bvlAYtPUmOSaldFpmycA%3D">new research</a>, published in the European Journal of Applied Physiology, we investigated the effects of eccentric walking on lower limb muscle strength and balance in 11 regular walkers aged 54 to 88 years. The intervention period was 12 weeks. It consisted of four weeks of normal walking followed by eight weeks of eccentric walking. The number of eccentric steps in the eccentric walking period gradually increased over eight weeks from 100 to 1,000 steps (including lunges, downhill and downstairs steps). Participants took a total of 3,900 eccentric steps over the eight-week eccentric walking period while the total number of steps was the same as the previous four weeks. We measured the thickness of the participants’ front thigh muscles, muscle strength in their knee, their balance and endurance, including how many times they could go from a sitting position to standing in 30 seconds without using their arms. We took these measurements before the study started, at four weeks, after the conventional walking period, and at four and eight weeks into the eccentric walking period. We also tested their cognitive function using a digit symbol-substitution test at the same time points of other tests. And we asked participants to complete a questionnaire relating to their activities of daily living, such as dressing and moving around at home. Finally, we tested participants’ blood sugar, cholesterol levels and complement component 1q (C1q) concentrations, a potential <a href="https://faseb.onlinelibrary.wiley.com/doi/abs/10.1096/fj.14-262154">marker of sarcopenia</a> (muscle wasting with ageing). <h2>What did we find?</h2> We found no significant changes in any of the outcomes in the first four weeks when participants walked conventionally. From week four to 12, we found significant improvements in muscle strength (19%), chair-stand ability (24%), balance (45%) and a cognitive function test (21%). Serum C1q concentration decreased by 10% after the eccentric walking intervention, indicating participants’ muscles were effectively stimulated. The sample size of the study was small, so we need larger and more comprehensive studies to verify our findings and investigate whether eccentric walking is effective for sedentary people, older people, how the different types of eccentric exercise compare and the potential cognitive and mental health benefits. But, in the meantime, “eccentric walking” appears to be a beneficial exercise that will extend your healthspan. It may look a bit eccentric if we insert lunges while walking on the street, but the more people do it and benefit from it, the less eccentric it will become. <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/224159/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/ken-nosaka-169021">Ken Nosaka</a>, Professor of Exercise and Sports Science, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Image editing is extremely common these days, and not all of it is for nefarious purposes. However, in an age of rampant misinformation, how can we stay vigilant around suspicious images? <h2>What happened with the royal photo?</h2> A close look reveals at least eight inconsistencies with the image. Two of these relate to unnatural blur. Catherine’s right hand is unnaturally blurred, even though her left hand is sharp and at the same distance from the camera. The left side of Catherine’s hair is also unnaturally blurred, while the right side of her hair is sharp. These types of edits are usually made with a blur tool that softens pixels. It is often used to make the background of an image less distracting or to smooth rough patches of texture. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/581145/original/file-20240312-26-rhmkk1.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/581145/original/file-20240312-26-rhmkk1.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/581145/original/file-20240312-26-rhmkk1.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=358&fit=crop&dpr=1 600w, https://images.theconversation.com/files/581145/original/file-20240312-26-rhmkk1.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=358&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/581145/original/file-20240312-26-rhmkk1.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=358&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/581145/original/file-20240312-26-rhmkk1.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=450&fit=crop&dpr=1 754w, https://images.theconversation.com/files/581145/original/file-20240312-26-rhmkk1.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=450&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/581145/original/file-20240312-26-rhmkk1.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=450&fit=crop&dpr=3 2262w" alt="" /></a><figcaption>At least eight logical inconsistencies exist in the doctored image the Prince and Princess of Wales posted on social media. <a class="source" href="https://www.instagram.com/p/C4U_IqTNaqU/">Photo by the Prince of Wales/Chart by T.J.

You can see this with the repeated pattern on Louis’s (on the left) sweater and the tile on the ground. You can also see it with the step behind Louis’s legs and on Charlotte’s hair and sleeve. The zipper on Catherine’s jacket also doesn’t line up. The most charitable interpretation is that the princess was trying to remove distracting or unflattering elements. But the artefacts could also point to multiple images being blended together. This could either be to try to show the best version of each person (for example, with a smiling face and open eyes), or for another purpose. <blockquote class="twitter-tweet"> Like many amateur photographers, I do occasionally experiment with editing.

This sometimes happens without you even knowing. Take HDR (high dynamic range) images, for example. Point your iPhone or equivalent at a beautiful sunset and watch it capture the scene from the brightest highlights to the darkest shadows. What happens here is your camera makes multiple images and automatically stitches them together to make an image <a href="https://www.adobe.com/creativecloud/photography/hub/guides/what-is-hdr-photography.html">with a wider range of contrast</a>. While face-smoothing or teeth-whitening filters are nothing new, some smartphone camera apps apply them without being prompted. Newer technology like Google’s “Best Take” <a href="https://blog.google/products/photos/how-google-photos-best-take-works/">feature</a> can even combine the best attributes of multiple images to ensure everyone’s eyes are open and faces are smiling in group shots. On social media, it seems everyone tries to show themselves in their best light, which is partially why so few of the photos on our <a href="https://www.tandfonline.com/doi/abs/10.1080/15551393.2020.1862663">camera rolls</a> make it onto our social media feeds. It is also why we often edit our photos to show our best sides. But in other contexts, such as press photography, the <a href="https://www.ap.org/about/news-values-and-principles/telling-the-story/visuals">rules are much stricter</a>. The Associated Press, for example, bans all edits beyond simple crops, colour adjustments, and “minor adjustments” that “restore the authentic nature of the photograph”. Professional photojournalists haven’t always gotten it right, though. While the majority of lens-based news workers adhere to ethical guidelines like those published by the <a href="https://nppa.org/resources/code-ethics">National Press Photographers Association</a>, others have let deadline pressures, competition and the desire for exceptional imagery cloud their judgement. One such example was in 2017, when British photojournalist Souvid Datta admitted to <a href="https://time.com/4766312/souvid-datta/">visually plagiarising</a> another photographer’s work within his own composition. <blockquote class="twitter-tweet"> Photographer Souvid Datta appears to have plagiarized Mary Ellen Mark: <a href="https://t.co/iO1Lm8CowU">https://t.co/iO1Lm8CowU</a> <a href="https://t.co/jswHyApGNj">pic.twitter.com/jswHyApGNj</a> — PetaPixel (@petapixel) <a href="https://twitter.com/petapixel/status/859824132258537472?ref_src=twsrc%5Etfw">May 3, 2017</a></blockquote> Concerns around false or misleading visual information are at an all-time high, given advances in <a href="https://theconversation.com/nine-was-slammed-for-ai-editing-a-victorian-mps-dress-how-can-news-media-use-ai-responsibly-222382">generative artificial intelligence (AI)</a>.

It placed this above armed conflict and natural disasters. <h2>What to do if you’re unsure about an image you’ve found online</h2> It can be hard to keep up with the more than <a href="https://theconversation.com/3-2-billion-images-and-720-000-hours-of-video-are-shared-online-daily-can-you-sort-real-from-fake-148630">3 billion photos</a> that are shared each day.

Why our voices change as we get older

<a href="https://theconversation.com/profiles/adam-taylor-283950">Adam Taylor</a>, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a> Sir Elton John set a record at this year’s Glastonbury, becoming the <a href="https://www.independent.co.uk/arts-entertainment/music/news/elton-john-glastonbury-viewing-record-b2364260.html">most-watched headliner</a> in the festival’s history, with more than 7 million people tuning in live to the BBC to watch his last ever UK performance. The 76-year-old singer certainly delivered all his characteristic showmanship. But many who have followed his music over the decades will have noticed how much his voice has changed during his career – and not only because of the <a href="https://www.billboard.com/music/music-news/a-qa-with-elton-john-65620/">surgery he had</a> in the 1980s to <a href="https://ultimateclassicrock.com/elton-john-throat-surgery/">remove polyps</a> from his vocal cords. Equally, it’s not all down to the process of ageing. While it’s no mystery that this affects every part of our body, it isn’t the only reason that a person’s voice – even a professional singer like Sir Elton – can sound quite different over the years. <h2>The sound of your voice</h2> The vocal cords are what produce the sound of your voice. They are located in the <a href="https://www.ncbi.nlm.nih.gov/books/NBK538202/">larynx</a>, a part of the respiratory system that allows air to pass from your throat to your lungs. When air passes out of the lungs and through the larynx, it causes the vocal cords to vibrate – <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5412481/">producing sound</a>. The vocal cords are composed of <a href="https://www.kenhub.com/en/library/anatomy/vocal-cords">three main parts</a>: the vocalis muscle, vocal ligament, and a mucous membrane (containing glands) to cover them. This keeps the surface moist and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2810851/">protects them from damage</a>. There are also approximately <a href="https://radiopaedia.org/articles/intrinsic-muscles-of-the-larynx?lang=gb">17 other muscles</a> in the larynx that can alter vocal cord position and tension – thus changing the sound produced. Pre-puberty, there’s very little difference in the sound the vocal cords produce. But during puberty, hormones begin exerting their effects. This changes the structure of the larynx – making the “Adam’s apple” more prominent in men – and the <a href="https://www.sciencedirect.com/science/article/abs/pii/S0018506X16301271?via%3Dihub">length of the vocal cords</a>. After puberty, they’re around 16mm in length in men, and 10mm in women. Women’s vocal cords are also <a href="https://pubs.aip.org/asa/jasa/article/82/S1/S90/719336/Physiology-of-the-female-larynx">20-30%</a> thinner after puberty. These shorter, thinner vocal cords are the reason why women typically have <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3306615">higher voices</a> than men. Even after puberty, hormones can affect the voice. For instance, a woman’s voice may sound different depending on the stage of her menstrual cycle – with the <a href="https://www.jvoice.org/article/S0892-1997(08)00169-0/fulltext">best voice quality</a> being in the ovulatory phase. This is because the glands produce most mucous during this phase, giving the vocal cords their best functional ability. Research also shows that women taking the contraceptive pill show <a href="https://www.sciencedirect.com/science/article/abs/pii/S0892199717304940">less variation in voice quality</a> because the pill halts ovulation. On the other hand, hormonal changes during the premenstrual phase impede the vocal cords, making them stiffer. This may explain why opera singers would be offered “<a href="https://www.sciencedirect.com/science/article/abs/pii/S0892199717301133">grace days</a>” in the 1960s to ensure they didn’t damage their vocal cords. And, because <a href="https://www.asha.org/practice-portal/clinical-topics/voice-disorders/#collapse_1">women’s vocal cords</a> are thinner, they may also be more likely to <a href="https://pubmed.ncbi.nlm.nih.gov/15157130/">suffer damage</a> from overuse. <h2>Everything ages</h2> As with almost every other part of the body, vocal cords age. But these changes might not be as <a href="https://www.sciencedirect.com/science/article/pii/S0892199721000011">noticeable for everyone</a>. As we get older, the larynx begins increasing its <a href="https://www.sciencedirect.com/science/article/abs/pii/S1752928X21001840">mineral content</a>, making it stiffer and more like bone than cartilage. This change can begin happening as early as <a href="https://meridian.allenpress.com/angle-orthodontist/article/75/2/196/57743/Ossification-of-Laryngeal-Cartilages-on-Lateral">your thirties</a> – especially in men. This makes the vocal cords less flexible. The muscles that allow the vocal cords to move also <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6166195/">begin wasting</a> (as do our other muscles) as we age. The ligaments and tissues that support the vocal cords also <a href="https://pubmed.ncbi.nlm.nih.gov/11800365/">lose elasticity</a>, becoming <a href="https://pubmed.ncbi.nlm.nih.gov/25645525/">less flexible</a>. There’s also a decrease in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2695176/">pulmonary muscle function</a>, reducing the power of the air expelled from the lungs to create the sound. The number of glands that produce the protective mucus also decrease, alongside a reduction in the ability to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10156980/">control the larynx</a>. <h2>Lifestyle is a factor</h2> While vocal cords age at largely the same rate in most people, many lifestyle factors can increase the risk of damage to them – and so can change the way your voice sounds. Smoking, for example, causes <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3918293/">localised inflammation</a>, increased <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4824943/">mucous production</a>, but can also <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4557797/">dry out</a> the mucosal surfaces. Alcohol has a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6166195/">similar effect</a>. Over time, these factors can damage the vocal cords and alter the voice’s sound. Some over-the-counter and prescription drugs can also alter the voice – such as <a href="https://jamanetwork.com/journals/jamaotolaryngology/fullarticle/482932">steroid inhalers used for laryngitis</a>. Blood thinners may also <a href="https://pubmed.ncbi.nlm.nih.gov/10875579/">damage the vocal cords</a> and can cause polyps to form, making the voice sound raspy or hoarse. <a href="https://pubmed.ncbi.nlm.nih.gov/7395839/">Muscle relaxants</a>, too, can lead to irritation and vocal cord damage due to the drug allowing stomach acid to wash back into the larynx. Thankfully, the irritation and changes caused by these medications typically disappears after stopping use. One other lifestyle factor can be overuse, which is typically seen in singers and other people who use their voice a lot <a href="https://pubmed.ncbi.nlm.nih.gov/15157130/">during work</a>, such as teachers and fitness instructors. This can lead to an uncommon condition called <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9392404/">Reinke’s oedema</a>, which can also be caused by smoking. Reinke’s oedema causes fluid to swell in the vocal cords, changing the pitch of the voice – often <a href="https://www.cuh.nhs.uk/patient-information/reinkes-oedema/">making it deeper</a>. In extreme cases of Reinke’s oedema, <a href="https://link.springer.com/article/10.1007/s00405-022-07377-9">surgery is needed</a> to drain the fluid. But in most cases, rest and avoiding irritants (smoking and alcohol) is beneficial, while speech and language therapy can also address the <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1460-6984.1995.tb01660.x">change in sound</a>. <h2>Maintaining our vocal quality</h2> While we can’t help some of the age-related changes that happen to our vocal cords, we can maintain some of our vocal quality and ability through continued use. This may explain why, in many cases, singers show <a href="https://pubmed.ncbi.nlm.nih.gov/27049451/">significantly less vocal change</a> with age than their non-singing counterparts. Singing or <a href="https://www.aarp.org/health/healthy-living/info-2014/improve-aging-voice.html">reading out</a> loud daily can give the vocal cords sufficient exercise to slow their decline. <a href="https://www.nidcd.nih.gov/health/taking-care-your-voice">Looking after</a> your vocal cords is also important. Staying hydrated and limiting intake of <a href="https://www.cuh.nhs.uk/patient-information/presbyphonia/">alcohol</a> and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7069957/">tobacco</a> can help prevent high rates of decline and damage.<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/208640/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/adam-taylor-283950">Adam Taylor</a>, Professor and Director of the Clinical Anatomy Learning Centre, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"Flower grannies" at their grandkids' wedding go viral

Two grandmothers have stolen the show at their grandkids' wedding as they walked down the aisle as flower girls. The heartwarming moment was captured by wedding photographer Joshua Hugget, who was taking photos at the picturesque wedding in South Australia. The video shows the two grandmothers arm-in-arm, dropping flower petals down the aisle in lieu of the standard young flower girls. The bride, Michaela Treloar, shared with the <a href="https://www.abc.net.au/news/2024-03-03/grandmothers-who-were-flower-girls-become-viral-sensation/103519006?sf271999625=1&fbclid=IwAR21H0d9_RfQkyBfP6SuyI1L_3KN8a4CdTXqqmx8tEfN8SyIp3FXY_ryqbg_aem_AZyZ59VDrmi0hZ-kcRd9Yncw5hZywZzo313-pUSnNYZJ-K_2Z4fXcOVlFcvX0Gn-E40">ABC</a> how she and her partner both “wanted to include our grandmothers into our wedding somehow”, which resulted in the adorable moment. <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-permalink="https://www.instagram.com/reel/C3hCIP9PgsG/?utm_source=ig_embed&utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"> </div> </div> </div> <div style="padding: 19% 0;"> </div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"> </div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <div style="padding: 12.5% 0;"> </div> <div style="display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;"> <div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);"> </div> <div style="background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;"> </div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);"> </div> </div> <div style="margin-left: 8px;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;"> </div> <div style="width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);"> </div> </div> <div style="margin-left: auto;"> <div style="width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);"> </div> <div style="background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);"> </div> <div style="width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);"> </div> </div> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;"> </div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/reel/C3hCIP9PgsG/?utm_source=ig_embed&utm_campaign=loading" target="_blank" rel="noopener">A post shared by Joshua Huggett Media (@joshuahuggettmedia)</a> </div> </blockquote> “They took it on with pride, smashed it, and now they’ve gone viral,” exclaimed Treloar. “It was really cute … each nonna was helping each other get to the end of the aisle, chatting all the way.” The photographer who captured the moment shared that he believes something about the video is relatable to everyone in some way, and that is the secret to its success. “It hits that heart string straight away … it’s the perfect concoction of people saying they want to do that with their grandma, teamed with people saying they wish they could do that with their grandma now that they’d passed,” Joshua shared.

MH370 disappearance 10 years on: can we still find it

<a href="https://theconversation.com/profiles/charitha-pattiaratchi-110101">Charitha Pattiaratchi</a>, <a href="https://theconversation.com/institutions/the-university-of-western-australia-1067">The University of Western Australia</a> It has been ten years since Malaysia Airlines passenger flight MH370 <a href="https://theconversation.com/lessons-to-learn-despite-another-report-on-missing-flight-mh370-and-still-no-explanation-100764">disappeared on March 8 2014</a>. To this day it remains one of the biggest aviation mysteries globally. It’s unthinkable that a modern Boeing 777-200ER jetliner with 239 people on board can simply vanish without any explanation. Yet multiple searches in the past decade have still not yielded the main wreckage or the bodies of the victims. At a remembrance event held earlier this week, the Malaysian transport minister announced <a href="https://www.reuters.com/world/asia-pacific/malaysia-says-mh370-search-must-go-10-years-after-plane-vanished-2024-03-03/">a renewed push for another search</a>. If approved by the Malaysian government, the survey will be conducted by United States seabed exploration firm Ocean Infinity, whose efforts were unsuccessful in 2018. <h2>What happened to MH370?</h2> The flight was scheduled to fly from Kuala Lumpur to Beijing. Air traffic control lost contact with the aircraft within 60 minutes into the flight over the South China Sea. Subsequently, it was tracked by military radar crossing the Malay Peninsula and was last located by radar over the Andaman Sea in the northeastern Indian Ocean. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/579774/original/file-20240305-18-vdbysn.png?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/579774/original/file-20240305-18-vdbysn.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/579774/original/file-20240305-18-vdbysn.png?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=375&fit=crop&dpr=1 600w, https://images.theconversation.com/files/579774/original/file-20240305-18-vdbysn.png?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=375&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/579774/original/file-20240305-18-vdbysn.png?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=375&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/579774/original/file-20240305-18-vdbysn.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=471&fit=crop&dpr=1 754w, https://images.theconversation.com/files/579774/original/file-20240305-18-vdbysn.png?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=471&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/579774/original/file-20240305-18-vdbysn.png?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=471&fit=crop&dpr=3 2262w" alt="A map of the region showing the initial search areas on 8-16 March." /></a><figcaption>The planned route, final route and initial search area for MH370 in Southeast Asia. <a class="source" href="https://en.wikipedia.org/wiki/Timeline_of_Malaysia_Airlines_Flight_370#/media/File:MH370_initial_search_Southeast_Asia.svg">Andrew Heenen/Wikimedia Commons</a>, <a class="license" href="http://creativecommons.org/licenses/by/4.0/">CC BY</a></figcaption></figure> Later, automated satellite communications between the aircraft and British firm’s Inmarsat telecommunications satellite indicated that the plane ended up in the southeast Indian Ocean <a href="https://hub.arcgis.com/datasets/4c94d33cfc144f7d8b78943dee56e29b/explore">along the 7th arc</a> (an arc is a series of coordinates).

Google Earth/Author provided</figcaption></figure> <h2>What have searches for MH370 found so far?</h2> On March 18 2014, ten days after the disappearance of MH370, a search in the southern Indian Ocean <a href="https://www.atsb.gov.au/publications/2014/considerations-on-defining-the-search-area-mh370">was led by Australia</a>, with participation of aircraft from several countries. This search continued until April 28 and covered an area of 4,500,000 square kilometres of ocean. No debris was found. Two underwater searches of the Indian Ocean, 2,800km off the coast of Western Australia, have also failed to find any evidence of the main crash site. The initial seabed search, led by Australia, covered 120,000 square kilometres and extended 50 nautical miles across the 7th arc. It took 1,046 days and was suspended on January 17 2017. A second search by Ocean Infinity in 2018 <a href="https://oceaninfinity.com/conclusion-of-current-search-for-malaysian-airlines-flight-mh370/">covered over 112,000 square kilometres</a>. It was completed in just over three months but also didn’t locate the wreckage. <h2>What about debris?</h2> While the main crash site still hasn’t been found, several pieces of debris have washed up in the years since the flight’s disappearance. In fact, in June 2015 officials from the Australian Air Transport Safety Bureau determined that debris might arrive in Sumatra, contrary to the ocean currents in the region. The strongest current in the Indian Ocean is the South Equatorial Current. It flows east to west between northern Australia and Madagascar, and debris would be able to cross it. Indeed, on July 30 2015 a large piece of debris – a <a href="https://en.wikipedia.org/wiki/Flaperon">flaperon</a> (moving part of a plane wing) – washed up on Reunion Island in the western Indian Ocean. It was later confirmed to belong to MH370. Twelve months earlier, using an oceanographic drift model, our University of Western Australia (UWA) modelling team had predicted that any debris originating from the 7th arc would end up in the western Indian Ocean. In subsequent months, additional aircraft debris was found in the western Indian Ocean in Mauritius, Tanzania, Rodrigues, Madagascar, Mozambique and South Africa. The UWA drift analysis accurately predicted where floating debris from MH370 would beach in the western Indian Ocean. It also guided American adventurer Blaine Gibson and others to directly recover several dozen pieces of debris, three of which <a href="https://www.newsweek.com/where-blaine-gibson-now-malaysia-airlines-mh370-debris-hunter-1787369">have been confirmed</a> to be from MH370, while several others <a href="https://www.airlineratings.com/news/mh370-debris-now-for-the-facts/">are deemed likely</a>. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/579756/original/file-20240305-22-q62h9n.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/579756/original/file-20240305-22-q62h9n.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/579756/original/file-20240305-22-q62h9n.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=602&fit=crop&dpr=1 600w, https://images.theconversation.com/files/579756/original/file-20240305-22-q62h9n.jpeg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=602&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/579756/original/file-20240305-22-q62h9n.jpeg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=602&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/579756/original/file-20240305-22-q62h9n.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=757&fit=crop&dpr=1 754w, https://images.theconversation.com/files/579756/original/file-20240305-22-q62h9n.jpeg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=757&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/579756/original/file-20240305-22-q62h9n.jpeg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=757&fit=crop&dpr=3 2262w" alt="A detailed satellite map showing locations of debris found on the shores of Africa and Madagascar." /></a><figcaption>Predicted locations of landfall from results of University of Western Australia drift modelling.

Charitha Pattiaratchi/UWA, Author provided</figcaption></figure> To date, these debris finds in the western Indian ocean are the only physical evidence found related to MH370. It is also independent verification that the crash occurred close to the 7th arc, as any debris would initially flow northwards and then to the west, transported by the prevailing ocean currents. These results are consistent with other drift studies undertaken by independent researchers globally. <h2>Why a new search for MH370 now?</h2> Unfortunately, the ocean is a chaotic place, and even oceanographic drift models cannot pinpoint the exact location of the crash site. The proposed new search by Ocean Infinity has significantly narrowed down the target area within latitudes 36°S and 33°S. This is approximately 50km to the south of the locations where UWA modelling indicated the release of debris along the 7th arc. If the search does not locate the wreckage, it could be extended north. Since the initial underwater searches, technology has tremendously improved. Ocean Infinity is using a fleet of autonomous underwater vehicles with improved resolution. The proposed search will also use remotely controlled surface vessels. In the area where the search is to take place, the ocean is around 4,000 metres deep. The water temperatures are 1–2°C, with low currents. This means that even after ten years, the debris field would be relatively intact. Therefore, there is a high probability that the wreckage can still be found. If a future search is successful, this would bring closure not just to the families of those who perished, but also the thousands of people who have been involved in the search efforts.<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/224954/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/charitha-pattiaratchi-110101">Charitha Pattiaratchi</a>, Professor of Coastal Oceanography, <a href="https://theconversation.com/institutions/the-university-of-western-australia-1067">The University of Western Australia</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Travel Trouble

How to be kind to yourself (without going to a day spa)

<a href="https://theconversation.com/profiles/lydia-brown-179583">Lydia Brown</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> “I have to be hard on myself,” Sarah told me in a recent telehealth psychology session. “I would never reach my potential if I was kind and let myself off the hook.” I could empathise with this fear of self-compassion from clients such as Sarah (not her real name). From a young age, we are taught to be kind to others, but self-kindness is never mentioned. Instead, we are taught success hinges on self-sacrifice. And we need a healthy inner critic to bully us forward into becoming increasingly better versions of ourselves. But <a href="https://journals.sagepub.com/doi/abs/10.1177/0146167212445599">research shows</a> there doesn’t have to be a trade-off between self-compassion and success. Self-compassion can help you reach your potential, while supporting you to face the inevitable stumbles and setbacks along the way. <h2>What is self-compassion?</h2> <a href="https://self-compassion.org/">Self-compassion</a> has <a href="https://www.tandfonline.com/doi/abs/10.1080/15298860309027">three</a> key ingredients. 1. Self-kindness This involves treating yourself with the same kindness you would extend towards a good friend – via your thoughts, feelings and actions – especially during life’s difficult moments. For instance, if you find yourself fixating on a minor mistake you made at work, self-kindness might involve taking a ten-minute walk to shift focus, and reminding yourself it is OK to make mistakes sometimes, before moving on with your day. 2. Mindfulness In this context, mindfulness involves being aware of your own experience of stress or suffering, rather than repressing or avoiding your feelings, or over-identifying with them. Basically, you must see your stress with a clear (mindful) perspective before you can respond with kindness. If we avoid or are consumed by our suffering, we lose perspective. 3. Common humanity Common humanity involves recognising our own experience of suffering as something that unites us as being human. For instance, a sleep-deprived parent waking up (for the fourth time) to feed their newborn might choose to think about all the other parents around the world doing exactly the same thing – as opposed to feeling isolated and alone. <h2>It’s not about day spas, or booking a manicure</h2> When Sarah voiced her fear that self-compassion would prevent her success, I explained self-compassion is distinct from self-indulgence. “So is self-compassion just about booking in more mani/pedis?” Sarah asked. Not really, I explained. A one-off trip to a day spa is unlikely to transform your mental health. Instead, self-compassion is a flexible <a href="https://link.springer.com/chapter/10.1007/978-3-031-22348-8_7">psychological resilience factor</a> that shapes our thoughts, feelings and actions. It’s associated with a suite of benefits to our <a href="https://iaap-journals.onlinelibrary.wiley.com/doi/abs/10.1111/aphw.12051">wellbeing</a>, <a href="https://www.tandfonline.com/doi/abs/10.1080/15298868.2011.639548">relationships</a> and <a href="https://www.tandfonline.com/doi/abs/10.1080/17437199.2019.1705872">health</a>. <h2>What does the science say?</h2> Over the past 20 years, we’ve learned self-compassionate people enjoy a wide range of benefits. They tend to be <a href="https://iaap-journals.onlinelibrary.wiley.com/doi/abs/10.1111/aphw.12051">happier</a> and have <a href="https://doi.org/10.1016/j.cpr.2012.06.003">fewer psychological symptoms</a> of distress. Those high on self-compassion <a href="https://journals.sagepub.com/doi/abs/10.1177/0146167212445599">persevere</a> following a failure. They say they are more motivated to overcome a personal weakness than those low on self-compassion, who are more likely to give up. So rather than feeling trapped by your inadequacies, self-compassion encourages a <a href="https://hbr.org/2018/09/give-yourself-a-break-the-power-of-self-compassion">growth mindset</a>, helping you reach your potential. However, self-compassion is not a panacea. It will not change your life circumstances or somehow make life “easy”. It is based on the premise that life is hard, and provides practical tools to cope. <h2>It’s a factor in healthy ageing</h2> I research menopause and healthy ageing and am especially interested in the value of self-compassion through menopause and in the second half of life. Because self-compassion becomes important during life’s challenges, it can help people navigate physical symptoms (for instance, <a href="https://www.sciencedirect.com/science/article/pii/S0378512214001649?via%3Dihub">menopausal hot flushes</a>), life transitions such as <a href="https://journals.sagepub.com/doi/10.1177/0956797611429466">divorce</a>, and <a href="https://link.springer.com/chapter/10.1007/978-3-031-22348-8_7">promote healthy ageing</a>. I’ve also teamed up with researchers at <a href="https://www.autismspectrum.org.au/">Autism Spectrum Australia</a> to explore self-compassion in autistic adults. We found autistic adults report significantly <a href="https://link.springer.com/article/10.1007/s10803-022-05668-y">lower levels</a> of self-compassion than neurotypical adults. So we developed an online <a href="https://www.autismspectrum.org.au/blog/new-online-self-compassion-program-for-autistic-adults">self-compassion training program</a> for this at-risk population. <h2>Three tips for self-compassion</h2> You <a href="https://onlinelibrary.wiley.com/doi/abs/10.1002/jclp.21923">can learn</a> self-compassion with these three exercises. 1. What would you say to a friend? Think back to the last time you made a mistake. What did you say to yourself? If you notice you’re treating yourself more like an enemy than a friend, don’t beat yourself up about it. Instead, try to think about what you might tell a friend, and direct that same friendly language towards yourself. 2. Harness the power of touch Soothing human touch <a href="https://www.frontiersin.org/journals/psychiatry/articles/10.3389/fpsyt.2020.555058/full">activates</a> the parasympathetic “relaxation” branch of our nervous system and counteracts the fight or flight response. Specifically, self-soothing touch (for instance, by placing both hands on your heart, stroking your forearm or giving yourself a hug) <a href="https://www.sciencedirect.com/science/article/pii/S2666497621000655">reduces</a> cortisol responses to psychosocial stress. 3. What do I need right now? Sometimes, it can be hard to figure out exactly what self-compassion looks like in a given moment. The question “what do I need right now” helps clarify your true needs. For example, when I was 37 weeks pregnant, I woke up bolt awake one morning at 3am. Rather than beating myself up about it, or fretting about not getting enough sleep, I gently placed my hands on my heart and took a few deep breaths. By asking myself “what do I need right now?” it became clear that listening to a gentle podcast/meditation fitted the bill (even though I wanted to addictively scroll my phone).<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/223194/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/lydia-brown-179583">Lydia Brown</a>, Senior Lecturer in Psychology, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Caring

We talked to dozens of people about their experience of grief. Here’s what we learned (and how it’s different from what you might think)

<a href="https://theconversation.com/profiles/michelle-peterie-564209">Michelle Peterie</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> and <a href="https://theconversation.com/profiles/alex-broom-121063">Alex Broom</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Have you ever felt a sudden pang of sadness? A bird seems to stop and look you in the eye. A photo drops out of a messy drawer from long ago, in the mundanity of a weekend spring clean. Your day is immediately derailed, unsettled. You are pulled into something you thought was past. And yet, in being pulled back, you are grateful, reconnected, and grief-stricken all over again. “You’ll get over it”. “Give it time”. “You need time to move on”. These are common cultural refrains in the face of loss. But what if grief doesn’t play by the rules? What if grief is a different thing altogether? We talked to 95 people about their experiences of grief surrounding the loss of a loved one, and <a href="https://journals.sagepub.com/doi/10.1177/00380261241228412">their stories</a> provided a fundamentally different account of grief to the one often presented to us culturally. <h2>Disordered grief?</h2> Grief is often imagined as a time-bound period in which one processes the pain of loss – that is, adjusts to absence and works toward “moving on”. The bereaved are expected to process their pain within the confines of what society deems “normal”. The <a href="https://theconversation.com/explainer-what-is-the-dsm-and-how-are-mental-disorders-diagnosed-9568">DSM-5 psychiatric manual</a> says if grief drags on too long, in fact, it becomes a pathology (a condition with a medical diagnosis). “Prolonged grief disorder” is the name given to “persistent difficulties associated with bereavement that exceeded expected social, cultural, or religious expectations”. While there can be <a href="https://theconversation.com/why-prolonged-grief-should-be-listed-as-a-mental-disorder-4262">value</a> in clinical diagnostic categories such as this, the danger is they put artificial boundaries around emotions. The pathologisation of grief can be deeply alienating to those experiencing it, for whom the pressure to “move on” can be hurtful and counterproductive. The stories we gathered in our research were raw, complex and often fraught. They did not sit comfortably with commonsense understandings of how grief “should” progress. As bereaved daughter Barbara told us: "Grief is not in the little box, it doesn’t even come close to a little box." <h2>Grief starts early</h2> The tendency is to think of grief as something that happens post death. The person we love dies, we have a funeral, and the grief sets in. Then it slowly subsides with the steady march of time. In fact, grief often begins earlier, often in a clinical consultation where the words “terminal” or “nothing more we can do” are used. Or when a loved one is told “go home and get your life in order”. Grief can begin months or even years before bereavement. As the people we interviewed experienced it, loss was also cumulative. The gradual deterioration of a loved one’s health in the years or months before their death imposed other painful losses: the loss of chosen lifestyles, the loss of longstanding relational rhythms, the loss of shared hopes and anticipated futures. Many participants felt their loved ones – and, indeed, the lives they shared with them – slipping away long before their physical deaths. <h2>Living with the dead</h2> Yet the dead do not simply leave us. They remain with us, in memories, rituals and cultural events. From <a href="https://theconversation.com/what-ancient-cultures-teach-us-about-grief-mourning-and-continuity-of-life-86199">Mexico’s Dia de los Muertos</a> to <a href="https://theconversation.com/japans-obon-festival-how-family-commemoration-and-ancestral-worship-shapes-daily-life-179890">Japan’s Opon</a>, festivals of the dead play a key role in cultures around the world. In that way, remembering the dead remains a critical aspect of living. So too does <a href="https://theconversation.com/theres-not-always-closure-in-the-never-ending-story-of-grief-3096">the ongoing experience of grief</a>. Events of this kind are not merely celebratory. They are critical forms through which life and death, joy and grief, are brought together and integrated. The absence of remembering can hold its own trouble, as our participants’ accounts revealed. As bereaved wife Anna explained: "I just find it really frustrating and I do get quite angry and upset sometimes. I know that life goes on. I’d be talking to girlfriends and stuff like that and it’s like they’ve forgotten that I’ve lost my husband. They haven’t, but nothing really changed in their life. But for me, and my family, it has." Part of the problem, here, is the ambivalent role grief plays in advanced industrialised societies like ours. Many of our participants felt pressure to perform resilience or (in clinical terms) to <a href="https://journals.sagepub.com/doi/full/10.1177/1363459317724854">“recover” quickly after loss</a>. But whose interests does a swift recovery serve? An employer’s? Friends who just want to get on with a death-free life? And, even more importantly, mightn’t ongoing connections with the dead enable better living? Might bringing the dead along with us actually make for better deaths and better lives? Many of our participants felt their loved ones remained with them, and experienced their “absent presence” as a source of comfort. Grieving, in this context, involved spending time “with” the dead. Anna described her practice as follows: "I had a diary, so I just write stuff in it about how I’m feeling or something happened and I’ll say to [my deceased husband], it’s all to [my deceased husband], “Do you remember, blah, blah, blah.” I’ll just talk about that memory that I have of that particular time and I find that that helps." <h2>Caring for those who grieve</h2> Grief does not begin at death, but neither do relationships end there. To rush the bereaved through grief – to usher them towards “recovery” and the more comfortable territories of happiness and productivity – is to do them a disservice. And, perhaps more critically, ridding our lives of the dead and grief may, in the end, make for more limited and muted emotional lives.<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/223848/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/michelle-peterie-564209">Michelle Peterie</a>, Research Fellow, Sydney Centre for Healthy Societies, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> and <a href="https://theconversation.com/profiles/alex-broom-121063">Alex Broom</a>, Professor of Sociology & Director, Sydney Centre for Healthy Societies, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

We looked at 700 plant-based foods to see how healthy they really are. Here’s what we found

<a href="https://theconversation.com/profiles/laura-marchese-1271636">Laura Marchese</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> and <a href="https://theconversation.com/profiles/katherine-livingstone-324808">Katherine Livingstone</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> If you’re thinking about buying plant-based foods, a trip to the supermarket can leave you bewildered. There are plant-based burgers, sausages and mince. The fridges are loaded with non-dairy milk, cheese and yoghurt. Then there are the tins of beans and packets of tofu. But how much is actually healthy? Our nutritional audit of more than 700 plant-based foods for sale in Australian supermarkets has just been <a href="https://www.sciencedirect.com/science/article/pii/S0889157524000516">published</a>. We found some products are so high in salt or saturated fat, we’d struggle to call them “healthy”. <h2>We took (several) trips to the supermarket</h2> In 2022, we visited two of each of four major supermarket retailers across Melbourne to collect information on the available range of plant-based alternatives to meat and dairy products. We took pictures of the products and their nutrition labels. We then analysed the nutrition information on the packaging of more than 700 of these products. This included 236 meat substitutes, 169 legumes and pulses, 50 baked beans, 157 dairy milk substitutes, 52 cheese substitutes and 40 non-dairy yoghurts. <h2>Plant-based meats were surprisingly salty</h2> We found a wide range of plant-based meats for sale. So, it’s not surprising we found large variations in their nutrition content. Sodium, found in added salt and which contributes to <a href="https://www.heartfoundation.org.au/bundles/healthy-living-and-eating/salt-and-heart-health">high blood pressure</a>, was our greatest concern. The sodium content varied from 1 milligram per 100 grams in products such as tofu, to 2,000mg per 100g in items such as plant-based mince products. This means we could eat our entire <a href="https://www.betterhealth.vic.gov.au/health/healthyliving/salt">daily recommended sodium intake</a> in just one bowl of plant-based mince. An <a href="https://www.tandfonline.com/doi/full/10.1080/09637486.2022.2137786">audit</a> of 66 plant-based meat products in Australian supermarkets conducted in 2014 found sodium ranged from 316mg in legume-based products to 640mg in tofu products, per 100g. In a <a href="https://www.mdpi.com/2072-6643/11/11/2603">2019 audit</a> of 137 products, the range was up to 1,200mg per 100g. In other words, the results of our audit seems to show a consistent trend of plant-based meats <a href="https://www.tandfonline.com/doi/full/10.1080/09637486.2022.2137786">getting saltier</a>. <h2>What about plant-based milks?</h2> Some 70% of the plant-based milks we audited were fortified with calcium, a nutrient important for <a href="https://www.betterhealth.vic.gov.au/health/healthyliving/calcium">bone health</a>. This is good news as a <a href="https://www.mdpi.com/2072-6643/12/5/1254">2019-2020 audit</a> of 115 plant-based milks from Melbourne and Sydney found only 43% of plant-based milks were fortified with calcium. Of the fortified milks in our audit, almost three-quarters (73%) contained the <a href="https://www.eatforhealth.gov.au/food-essentials/five-food-groups/milk-yoghurt-cheese-andor-their-alternatives-mostly-reduced-fat">recommended amount of calcium</a> – at least 100mg per 100mL. We also looked at the saturated fat content of plant-based milks. Coconut-based milks had on average up to six times higher saturated fat content than almond, oat or soy milks. <a href="https://www.mdpi.com/2072-6643/12/5/1254">Previous audits</a> also found coconut-based milks were much higher in saturated fat than all other categories of milks. <h2>A first look at cheese and yoghurt alternatives</h2> Our audit is the first study to identify the range of cheese and yoghurt alternatives available in Australian supermarkets. Calcium was only labelled on a third of plant-based yoghurts, and only 20% of supermarket options met the recommended 100mg of calcium per 100g. For plant-based cheeses, most (92%) were not fortified with calcium. Their sodium content varied from 390mg to 1,400mg per 100g, and saturated fat ranged from 0g to 28g per 100g. <h2>So, what should we consider when shopping?</h2> As a general principle, try to choose whole plant foods, such as unprocessed legumes, beans or tofu. These foods are packed with vitamins and minerals. They’re also high in dietary fibre, which is good for your gut health and keeps you fuller for longer. If opting for a processed plant-based food, here are five tips for choosing a healthier option. 1. Watch the sodium Plant-based meat alternatives can be high in sodium, so look for products that have <a href="https://www.eatforhealth.gov.au/eating-well/how-understand-food-labels/food-labels-what-look">around</a> 150-250mg sodium per 100g. 2. Pick canned beans and legumes Canned chickpeas, lentils and beans can be healthy and low-cost <a href="https://www.heartfoundation.org.au/getmedia/71522940-decf-436a-ba44-cd890dc18036/Meat-Free-Recipe-Booklet.pdf">additions to many meals</a>. Where you can, choose canned varieties with no added salt, especially when buying baked beans. 3. Add herbs and spices to your tofu Tofu can be a great alternative to meat. Check the label and pick the option with the highest calcium content. We found flavoured tofu was higher in salt and sugar content than minimally processed tofu. So it’s best to pick an unflavoured option and add your own flavours with spices and herbs. 4. Check the calcium When choosing a non-dairy alternative to milk, such as those made from soy, oat, or rice, check it is fortified with calcium. A good alternative to traditional dairy will have at least 100mg of calcium per 100g. 5. Watch for saturated fat If looking for a lower saturated fat option, almond, soy, rice and oat varieties of milk and yoghurt alternatives have much lower saturated fat content than coconut options. Pick those with less than 3g per 100g.<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/222991/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/laura-marchese-1271636">Laura Marchese</a>, PhD Student at the Institute for Physical Activity and Nutrition, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> and <a href="https://theconversation.com/profiles/katherine-livingstone-324808">Katherine Livingstone</a>, NHMRC Emerging Leadership Fellow and Senior Research Fellow at the Institute for Physical Activity and Nutrition, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"Go enjoy your life": Young woman announces her own death

A young woman has announced the news of her own death after a gruelling battle with cancer, while sharing her wishes for her grieving loved ones. Daniella Thackray, a 25-year-old from Leeds, took to social media to share the her heart-breaking final words, after an eight-month battle with the rare disease. The young digital marketing specialist had pre-written the message for her family to post on her behalf after dying of cholangiocarcinoma, a type of cancer that forms in the bile ducts. The emotional message paid tribute to her family, fiancé Tom, and dog Leo, as she encouraged her loved ones to “enjoy the little things” in life and “cherish every moment” after she had “gone”. She wrote: “If you’re reading this then it means I have died from my battle with cancer and my family are posting my final message on my behalf. “Firstly, I just want to say that not all cancers are caused by lifestyle choices, in some cases it’s genetics or unfortunately it just happens." “In my case, despite me being very healthy and active, a cancer started in my bile ducts which was not caused by anything in my control and my life was never the same again." “Cholangiocarinoma is a rare aggressive cancer with often no obvious causes and no cure’.. I really really do hope that in the years to come more research is done about this horrid cruel disease so that more lives can be saved.” Despite her devastating diagnosis, she chose “not to mourn life” and make the most of her time. Daniella added: “So with that being said, although we can’t control what happens to us, we can control how we react. I chose not to mourn the life I was losing despite being so devastated, but to instead enjoy every moment I had left." “As I have always said and believed, you should enjoy the little things in life and cherish every moment! Romanticise your life! Do whatever makes you happy and don’t let anyone take the joy of life away from you." “I LOVED my life. Everything I had achieved was what I wanted. I loved my job, my fiancé, my family, my friends and my dog, and the house we were going to buy and the future we were making for ourselves." “Leo my fur baby was definitely brought into my life to help brighten my darkest days." “And lastly to my dear, beautiful Tom, I love you and always will. Thank you for supporting me and bringing so much love and happiness into my life. Go enjoy your life now, you deserve it.” Her message has already gained more than 30,000 likes, while hundreds of people rushed to leave their condolences to her loved ones. One person wrote, "Such courageous words from someone that I’ve never met. What a wonderful message to leave us with, may you rest in paradise.” Image credits: Facebook

Run out of butter or eggs? Here’s the science behind substitute ingredients

<a href="https://theconversation.com/profiles/paulomi-polly-burey-404695">Paulomi (Polly) Burey</a>, <a href="https://theconversation.com/institutions/university-of-southern-queensland-1069">University of Southern Queensland</a> It’s an all too common situation – you’re busy cooking or baking to a recipe when you open the cupboard and suddenly realise you are missing an ingredient. Unless you can immediately run to the shops, this can leave you scrambling for a substitute that can perform a similar function. Thankfully, such substitutes can be more successful than you’d expect. There are a few reasons why certain ingredient substitutions work so well. This is usually to do with the chemistry and the physical features having enough similarity to the original ingredient to still do the job appropriately. Let’s delve into some common ingredient substitutions and why they work – or need to be tweaked. <iframe id="IitfH" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/IitfH/1/" width="100%" height="400px" frameborder="0"></iframe> <h2>Oils versus butter</h2> Both butter and oils belong to a chemical class called <a href="https://chem.libretexts.org/Bookshelves/Introductory_Chemistry/Map%3A_Fundamentals_of_General_Organic_and_Biological_Chemistry_(McMurry_et_al.)/23%3A_Lipids/23.01%3A_Structure_and_Classification_of_Lipids">lipids</a>. It encompasses solid, semi-solid and liquid fats. In a baked product the “job” of these ingredients is to provide flavour and influence the structure and texture of the finished item. In cake batters, lipids contribute to creating an emulsion structure – this means combining two liquids that wouldn’t usually mix. In the baking process, this helps to create a light, fluffy crumb. One of the primary differences between butter and oil is that butter is only about 80% lipid (the rest being water), while <a href="https://www.nutritionadvance.com/types-of-cooking-fats-and-oils/">oil is almost 100% lipid</a>. Oil creates a softer crumb but is still a great fat to bake with. You can use a wide range of oils from different sources, such as olive oil, rice bran, avocado, peanut, coconut, macadamia and many more. Each of these may impart different flavours. Other “butters”, such as peanut and cashew butter, aren’t strictly butters but pastes. They impart different characteristics and can’t easily replace dairy butter, unless you also add extra oil. <h2>Aquafaba or flaxseed versus eggs</h2> Aquafaba is the liquid you drain from a can of legumes – such as chickpeas or lentils. It contains proteins, kind of how egg white also contains proteins. The proteins in egg white include albumins, and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5912395/">aquafaba also contains albumins</a>. This is why it is possible to make meringue from egg whites, or from aquafaba if you’re after a vegan version. The proteins act as a foam stabiliser – they hold the light, airy texture in the product. The concentration of protein in egg white is a bit higher, so it doesn’t take long to create a stable foam. Aquafaba requires more whipping to create a meringue-like foam, but it will bake in a similar way. Another albumin-containing alternative for eggs is <a href="https://foodstruct.com/compare/seeds-flaxseed-vs-egg">flaxseed</a>. These seeds form a thick gel texture when mixed with a little water. The texture is similar to raw egg and can provide structure and emulsification in baked recipes that call for a small amount of egg white. <h2>Lemon plus dairy versus buttermilk</h2> Buttermilk is the liquid left over after churning butter – it can be made from sweet cream, cultured/sour cream or whey-based cream. Buttermilk mostly <a href="https://www.journalofdairyscience.org/article/S0022-0302(06)72115-4/fulltext">contains proteins and fats</a>. Cultured buttermilk has a somewhat tangy flavour. Slightly soured milk can be a good substitute as it contains similar components and isn’t too different from “real” buttermilk, chemically speaking. One way to achieve slightly soured milk is by adding some lemon juice or cream of tartar to milk. Buttermilk is used in pancakes and baked goods to give extra height or volume. This is because the acidic (sour) components of buttermilk interact with baking soda, producing a light and airy texture. Buttermilk can also influence flavour, imparting a slightly tangy taste to pancakes and baked goods. It can also be used in sauces and dressings if you’re looking for a lightly acidic touch. <h2>Honey versus sugar</h2> Honey is a <a href="https://resources.perkinelmer.com/lab-solutions/resources/docs/APP_Analysis-of-Sugars-in-Honey-012101_01.pdf">complex sugar-based syrup</a> that includes floral or botanical flavours and aromas. Honey can be used in cooking and baking, adding both flavour and texture (viscosity, softness) to a wide range of products. If you add honey instead of regular sugar in baked goods, keep in mind that honey imparts a softer, moister texture. This is because it contains more moisture and is a humectant (that is, it likes to hold on to water). It is also less crystalline than sugar, unless you leave it to crystallise. The intensity of sweetness can also be different – some people find honey is sweeter than its granular counterpart, so you will want to adjust your recipes accordingly. <h2>Gluten-free versus regular flour</h2> Sometimes you need to make substitutions to avoid allergens, such as gluten – the protein found in cereal grains such as wheat, rye, barley and others. Unfortunately, gluten is also the component that gives a nice, stretchy, squishy quality to bread. To build this characteristic in a gluten-free product, it’s necessary to have a mixture of ingredients that work together to mimic this texture. Common ingredients used are corn or rice flour, xanthan gum, which acts as a binder and moisture holder, and tapioca starch, which is a good water absorbent and can aid with binding the dough. <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/202036/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/paulomi-polly-burey-404695">Paulomi (Polly) Burey</a>, Associate Professor (Food Science), <a href="https://theconversation.com/institutions/university-of-southern-queensland-1069">University of Southern Queensland</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Mother bans in-laws from seeing her baby after they go against her wishes

A woman has banned her in-laws from seeing her newborn daughter after they “betrayed her trust” and directly went against her wishes. The new mum shared the story to Reddit, as she explained why she was cutting contact with her husband’s parents after they pierced her child’s ears without their knowledge or consent. “My husband is from a culture where it's not uncommon to pierce baby girls' ears and his mother started pestering me about getting my daughter's ears pierced a few days after she was born,” the 32-year-old mum began. “I made it clear that I would not be doing that, and that I'd be waiting until she's old enough to ask for it herself. We live in my country where piercing a baby's ears isn't common at all.” The new mum's world soon came crashing down after the baby spent a weekend with her grandparents, before she went back to her parents red in the face and screaming. “My mother-in-law was looking after her over the weekend and decided to pierce her ears without my knowledge or consent.” “When I saw this I threw a fit. My baby was crying in pain, and I actually took her to the doctor to get their advice on whether or not to take them out.” The doctor advised the parent to take the earrings out as they were irritating the baby, but the issue didn’t end there. “I decided at that moment that my mother-in-law and everyone else on that side of the family (except for my sister-in-law, who's on my side about this) is going to have no alone contact with my daughter ever again - or at least until she's a teenager.” “My worry is that she'll do the same thing again, and to be frank, she's lost my trust entirely. I told her that if she had a problem with that, I'd report what she did to the police.” The husband of the baby girl reluctantly sided with his wife over the issue, despite saying it wasn’t a big deal and suggesting everyone move on from the incident. The story prompted a mixed response online, with some people saying the woman was overreacting and should work towards rebuilding trust with her in-laws. Others, however, had the opposite opinion, with one person saying, “Forget rebuilding trust, I'd be having them charged with assault.” Another person said, “They mutilated a child and they knew it was against the parents wishes. These people have serious problems. Not that I'd press charges, but getting holes poked in someone else's kid is a huge thing.” Image credits: Getty Images

Is Valentine’s Day worth the romantic investment? Here’s what we can learn from economics

<a href="https://theconversation.com/profiles/selma-wather-1510222">Selma Wather</a>, <a href="https://theconversation.com/institutions/university-of-sussex-1218">University of Sussex</a> Expressing affection can be expensive. Spending on heart-shaped gifts, romantic cards, chocolates and flowers (other gifts are available) to celebrate Valentine’s Day has reached <a href="https://www.statista.com/statistics/510981/valentines-day-total-spending-great-britain/#:%7E:text=In%20the%20United%20Kingdom%20%28UK%29%20alone%2C%20Valentine%E2%80%99s%20Day,increased%20by%20just%20over%20300%20million%20British%20pounds.">close to £1 billion</a> in the UK. So the value of Valentine’s to retailers seems clear enough. But just how valuable is the annual ritual to consumers? What return can you expect for the money you invest in that bouquet of roses or candle lit meal? Broadly speaking, and depending on your relationship status, buying into Valentine’s Day traditions suggests two possible scenarios. You might be sending a card or gift to a potential partner to inform them of your interest; or you might be giving something to your current partner to remind them of your continuing love. Research suggests that both options have intrinsic economic value. For those seeking to express interest, sending a card is like dipping your toe into what economists might refer to as the “marriage market” – the search for someone you like, who likes what you have to offer in return. This search can happen smoothly, with plenty of information about your potential match, or it can be paved with obstacles, where you may not know much about who is available, and <a href="https://papers.ssrn.com/sol3/papers.cfm?abstract_id=1703310">learning about potential partners</a> takes time. So suppose you are searching for a partner, and comprehensive information about potential matches is not freely available. What do you do? One option might be to put all your hopes into meeting someone on your daily journey to work. You pray that one day, just like in the movies, you will simply bump into “the one”. A second option might be to focus your search on single work colleagues, or people you know socially, and send Valentine’s Day cards to those you are attracted to. The option with the highest chance of success is the second one. You are using reliable information – knowledge of who is single. And sending a card to them can provide them with important information about you – that you’re also single, and that you’re interested. This is why research suggests that sending a Valentine’s Day card can be a <a href="https://www.jstor.org/stable/2938374?origin=crossref">logical investment</a> of time and money. <h2>‘Match quality’</h2> Fast forward five years or so and imagine you are happily married to the recipient of one of those cards. Is it worth repeating the gesture now that you’re settled down together? Economists think of marriages or partnerships as having an inherent “<a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1468-2354.2006.00385.x">match quality</a>”, which reflects how good (or bad) your relationship is – and the likelihood of you breaking up. If match quality falls below the level of happiness you might expect to have if you were to leave, a <a href="https://papers.ssrn.com/sol3/papers.cfm?abstract_id=2759255">separation may well follow</a>. But many studies also show that <a href="https://www.jstor.org/stable/2535409">match quality is malleable</a> – that it can change, for better and indeed for worse, over time. You can invest in trying to improve match quality in various ways. It might be starting a family, sharing hobbies and interests, or gestures such as cooking a special meal or exchanging gifts on the 14th day of February. Improving your match quality <a href="https://www.researchgate.net/publication/228431914_How_Does_the_Change_of_Marriage_Quality_Affect_Divorce_Decisions">directly reduces the probability</a> of a separation. Then there’s the question of commitment – the willingness to stay in a relationship rather than walking away. And again, gestures can make a difference. Imagine you have just started a new job, and your employer asks you to complete an intensive training session in your free time, for a skill that would only be useful for that particular role. If you expect to hold the job for a long period, you might happily invest your time. But if your employer is struggling financially and redundancy is on the cards, you are much less likely to agree to perform the task. Relationships work in a similar way. People are more prepared to invest in things like having children or buying a house together if they expect the relationship to last. Given that commitment is not guaranteed by a marriage certificate, people <a href="https://papers.ssrn.com/sol3/papers.cfm?abstract_id=950688">need to find other ways</a> to signal their continued devotion. Celebrating Valentine’s Day is one way of making such a signal. It can show faith in your shared commitment, signify that you wish to continue investing in the relationship and improve match quality, further stabilising the partnership. So even if deep down you think that Valentine’s Day has become over commercialised and meaningless, research suggests it makes good economic sense to send that card.<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/223128/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/selma-wather-1510222">Selma Wather</a>, Senior Lecturer in Economics, <a href="https://theconversation.com/institutions/university-of-sussex-1218">University of Sussex</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.
