Ozempic, Wegovy, Rybelsus: Are we losing sight of overall health? Here’s what the science says

<p><em><a href="https://theconversation.com/profiles/aude-bandini-1488512">Aude Bandini</a>, <a href="https://theconversation.com/institutions/universite-de-montreal-1743">Université de Montréal</a>; <a href="https://theconversation.com/profiles/jean-philippe-drouin-chartier-1533338">Jean-Philippe Drouin-Chartier</a>, <a href="https://theconversation.com/institutions/universite-laval-1407">Université Laval</a>; <a href="https://theconversation.com/profiles/pierre-marie-david-1375228">Pierre-Marie David</a>, <a href="https://theconversation.com/institutions/universite-de-montreal-1743">Université de Montréal</a>, and <a href="https://theconversation.com/profiles/remi-rabasa-lhoret-1533515">Rémi Rabasa-Lhoret</a>, <a href="https://theconversation.com/institutions/universite-de-montreal-1743">Université de Montréal</a></em></p> <p>The craze for new drugs in the GLP-1 (Glucagon-like peptide 1) and GIP (Gastric inhibitory polypeptide) analogue class, better known under the trade names Ozempic and Wegovy, is remarkable, but it’s not totally unprecedented in the history of pharmaceutical blockbusters.</p> <p>The volume of prescriptions and the budget allocated to them by public health insurance schemes are exploding, as are the <a href="https://www.forbes.com/sites/roberthart/2024/05/02/ozempic-maker-novo-nordisk-beats-profit-forecasts-amid-weight-loss-drug-frenzy/">profits of the companies that manufacture them</a>.</p> <p>Part of the popularity of these drugs owes to social networks, but these are not always the best source for health information. When it comes to the subject of weight loss, both fantasy and prejudice come into play. This works to the detriment of everyone’s well-being, but particularly those who are already stigmatized.</p> <p>As specialists in the philosophy of medicine (Université de Montréal), nutrition and food science (Université Laval), the sociology of medication (Université de Montréal) and endocrinology (Institut de recherches cliniques de Montréal), we feel it’s necessary to step back and take stock of both the promises and the limitations of these new treatments.</p> <h2>The best of both worlds</h2> <p>GLP-1/GIP analogues were originally developed to regulate glycemia (blood sugar levels) in people with Type 2 diabetes, thereby preventing the complications associated with this disease. When studies were carried out to assess their safety and efficacy, it was discovered that these drugs also led to weight loss. This prompted new research which showed that at higher doses, the drugs could lead to <a href="https://pubmed.ncbi.nlm.nih.gov/38078870/">very significant weight loss</a>, from 15 to 25 per cent of the starting weight.</p> <p>The mode of action of these drugs on blood sugar regulation is clear: they simulate incretin hormones which, in turn, increase insulin secretion. Weight loss, on the other hand, was only explained after the fact: in addition to the pancreas, these molecules also act on the brain by regulating the sensation of satiety and, indirectly, on the stomach by slowing gastric emptying. These two combined effects reduce appetite and lead to weight reduction.</p> <p>This is how a new use for the drug appeared, at which point the company Novo Nordisk began marketing the same drug under two different names: Ozempic to treat Type 2 diabetes, and <a href="https://theconversation.com/considering-taking-wegovy-to-lose-weight-here-are-the-risks-and-benefits-and-how-it-differs-from-ozempic-237308">Wegovy to manage obesity</a>.</p> <h2>A new era</h2> <p>GLP-1/GIP analogues are a welcome therapeutic breakthrough at a time when the <a href="https://www.diabetes.ca/advocacy---policies/advocacy-reports/national-and-provincial-backgrounders/diabetes-in-canada">prevalence of Type 2 diabetes</a> and <a href="https://www.statcan.gc.ca/o1/en/plus/5742-overview-weight-and-height-measurements-world-obesity-day">obesity</a> is exploding and affecting people younger and younger.</p> <p>These diseases particularly affect women, members of racialized groups and socio-economically disadvantaged populations. The physical and mental suffering these cause and the costs associated with treating them are both considerable. So the arrival of new weapons in the therapeutic arsenal is a source of hope.</p> <p>Draconian changes in lifestyle are certainly effective. But they are very difficult to implement and maintain over time for reasons that go beyond the individual sphere; on the one hand, genetic predisposition plays a major role in the development of Type 2 diabetes and obesity; on the other, because these conditions are <a href="https://obesitycanada.ca/managing-obesity/">multifactorial</a>, management of them must be comprehensive to be effective and long lasting: it must combine medical interventions but also nutritional, functional, psycho-social, environmental and even institutional interventions.</p> <p>Support services of this kind do exist, but only in large university hospital centres to which many people do not have access. Nor do many people have easy access to <a href="https://health-infobase.canada.ca/health-inequalities/index">healthy and varied food options</a>, sports facilities or social and psychological support.</p> <h2><strong>Treating the effects but not the causes</strong></h2> <p>To be effective over the long term, GLP-1/GIP analogues must be taken continuously: without drastic lifestyle changes, the <a href="https://pubmed.ncbi.nlm.nih.gov/35441470/">weight that was lost is regained within a year of stopping</a>, and glycemic control is compromised once again.</p> <p>In other words, the drugs treat the effects of Type 2 diabetes and obesity but not their causes. And yet some of these causes are modifiable: for example, according to <a href="https://www150.statcan.gc.ca/n1/pub/75-006-x/2023001/article/00013-eng.htm">Statistics Canada</a>, less than half the Canadian population (49.2 per cent for adults; 43.9 per cent for young people and children) achieves the recommended amount of weekly physical activity. According to the same source, <a href="https://www150.statcan.gc.ca/n1/pub/75-006-x/2023001/article/00013-eng.htm">food insecurity</a> affects around 14 per cent of the Québec population (22 per cent in Alberta).</p> <p>Pharmacological treatment, even if it allows an individual to eat less, does not necessarily mean that person will <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10837702/">eat better</a>. Similarly, losing weight does not mean one will become more active or healthier. So these new drugs do not cure Type 2 diabetes or obesity. Nor do they prevent these diseases from developing, although they do help to limit the many complications to which they give rise.</p> <h2><strong>Prescribe and treat</strong></h2> <p>A drug such as Mounjaro is as effective at weight loss as bariatric surgery. Much easier to administer and much less risky, it could be a real game changer in the treatment of obesity. Prescribed directly by family doctors and dispensed in pharmacies, it would also be much more accessible and easier to administer for those who need it.</p> <p>This raises the question of costs and reimbursement, but not only that: prescribing is not the same as treating. Here, the manufacturers are following the recommendations of the health authorities: this treatment must be preceded by a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10748770/">careful assessment</a>, then management, and above all a close and regular monitoring of diet, physical activity, mental health, and if necessary, socio-economic assistance.</p> <p>This requires not only time that GPs do not have, but also co-ordination with other players in the health-care network. The problem is not whether the treatment will be effective, but what can happen if it is. Losing 25 per cent of your body weight in just a few months has serious consequences, which are not always beneficial: it involves a loss of body fat, but also of muscle mass, which is associated with intense fatigue. Nor should we underestimate the <a href="https://pubmed.ncbi.nlm.nih.gov/37990685/">challenge of adapting physically and psychologically</a> to a body transformation of this scale. Losing weight doesn’t solve everything, and expectations must remain realistic.</p> <h2>What lessons can we learn?</h2> <p>The clinical effectiveness of GLP-1/GIP analogues in reducing the complications associated with Type 2 diabetes and obesity is indisputable. However, these drugs are not suitable for everyone, and they are certainly not miracle cures that will make it possible for one to regain health without making any changes to lifestyle or environment.</p> <p>We must bear in mind that their success, both commercial and medical, is also the result of a failure: that of our societies to prevent these diseases, to promote healthy lifestyles and to develop environments conducive to the health of all.<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/238484/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/aude-bandini-1488512"><em>Aude Bandini</em></a><em>, Professeure agrégée, Philosophie (épistémologie et philosophie de la médecine), <a href="https://theconversation.com/institutions/universite-de-montreal-1743">Université de Montréal</a>; <a href="https://theconversation.com/profiles/jean-philippe-drouin-chartier-1533338">Jean-Philippe Drouin-Chartier</a>, Professeur agrégé, Faculté de pharmacie, <a href="https://theconversation.com/institutions/universite-laval-1407">Université Laval</a>; <a href="https://theconversation.com/profiles/pierre-marie-david-1375228">Pierre-Marie David</a>, Professeur adjoint à la faculté de pharmacie, <a href="https://theconversation.com/institutions/universite-de-montreal-1743">Université de Montréal</a>, and <a href="https://theconversation.com/profiles/remi-rabasa-lhoret-1533515">Rémi Rabasa-Lhoret</a>, Professeur de médecine et de nutrition, <a href="https://theconversation.com/institutions/universite-de-montreal-1743">Université de Montréal</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Anti-cellulite products are big business – but here’s what the science says

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/rebecca-shepherd-423135">Rebecca Shepherd</a>, <em><a href="https://theconversation.com/institutions/university-of-bristol-1211">University of Bristol</a></em></p> <p>Although <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/jocd.14815">90% of women have cellulite</a>, we’re yet to see it represented as a normal anatomical characteristic in popular culture. In Greta Gerwig’s 2023 Hollywood blockbuster, for instance, Stereotypical Barbie, played by Margot Robbie, develops dimples on her upper thigh as part of her existential crisis – along with other human faults such as halitosis, flat feet and irrepressible thoughts of death.</p> <p>When Stereotypical Barbie asks doll sage Weird Barbie what the dimples are, she explains: “That’s cellulite. That’s going to spread everywhere. Then you’re going to start getting sad and mushy and complicated.” Barbie’s perfect smooth plastic perfection is marred.</p> <p>Despite its prevalence, then, cellulite has been constructed as a flaw in need of correction. Consumers, it seems, agree, especially when fed a diet of the <a href="https://www.tandfonline.com/doi/full/10.1080/21604851.2021.1913827">photoshop smoothed skin</a> of models, social media influencers – and Hollywood stars.</p> <figure><iframe src="https://www.youtube.com/embed/rmThigh1i8s?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">“NO!” Barbie shouts when Weird Barbie tells her she has cellulite.</span></figcaption></figure> <p>Cellulite’s usually found in areas that have greater amounts of subcutaneous fat, when fat deposits push through the connective tissue beneath the skin, leading to a lumpy appearance. It is common, <a href="https://www.sciencedirect.com/science/article/pii/S0738081X1300076X?via%3Dihub">usually painless</a> and harmless.</p> <p>The human skin is the <a href="https://theconversation.com/the-skin-is-a-very-important-and-our-largest-organ-what-does-it-do-91515">body’s largest organ</a>, made up of three layers. At the surface, the epidermis acts as our first line of defence against the environment. This outermost, impermeable layer is made up of cells that are constantly renewed and shed, protecting our body from external elements.</p> <p>Beneath the epidermis lies the dermis, a robust layer containing fibroblasts, the cells responsible for producing essential proteins such as collagen and elastin. These proteins provide structure and elasticity, contributing to the skin’s strength and flexibility.</p> <p>Deeper still is the hypodermis, also known as the subcutaneous layer. This layer is rich in adipose tissue – mostly made up of fat, which plays a crucial role in cushioning and insulating the body, as well as storing fat that can be used when needed. Beneath these three layers of skin, there is muscle. Running from the muscle to the dermis are <a href="https://journals.lww.com/amjdermatopathology/fulltext/2000/02000/cellulite__from_standing_fat_herniation_to.7.aspx">bands of connective tissue</a>, that holds the adipose tissue in “pockets”.</p> <p>Cellulite does not affect health, although some people report that it affects their <a href="https://www.tandfonline.com/doi/abs/10.1080/07853890.2018.1561731">self-esteem and body image</a> but that’s more to do with the social pressure on women to be physically perfect – or spend money, time and energy trying to be as close to perfect as possible.</p> <p>Cellulite, then, has become big business for the beauty industry. In the lead up to summer especially, companies will promote <a href="https://www.asa.org.uk/advice-online/weight-control-cellulite.html">all manner of products</a> from creams and serums to gadgets and pills, all aimed at creating perfectly smooth limbs. The most popular question seems to be, “Do these treatments work?” but as an anatomist I think the more pressing question is, “Why are healthy women’s bodies considered something to treat, cure or correct?”</p> <p>The beauty and wellness industry has long capitalised on societal standards of beauty. The idea that cellulite is undesirable and <a href="https://journals.lww.com/dermatologicsurgery/abstract/1978/03000/So_Called_Cellulite.9.aspx">should be corrected</a> has been perpetuated since Vogue magazine was the <a href="https://archive.vogue.com/article/1968/4/cellulite-the-new-word-for-fat-you-couldnt-lose-before">first English language magazine</a> to use the term “cellulite”, introducing the concept to thousands of women. This marketing strategy taps into the insecurities of consumers, particularly women, and promotes an endless pursuit of “perfection” for bodies that have normal anatomical variation.</p> <p>By framing cellulite as a condition that needs treatment, companies can sell a wide range of products and services, bolstered by celebrity endorsements, which lend credibility and aspirational value to pseudo-medical “smoothing” products. However, there is limited scientific evidence supporting the effectiveness of these supplements in treating cellulite. In fact, the <a href="https://onlinelibrary.wiley.com/doi/10.1111/j.1524-4725.1978.tb00416.x">first scientific paper</a> on cellulite, published in 1978, referred to it as “so called cellulite: the invented disease”.</p> <p>Recent product launches include, <a href="https://lemmelive.com/en-gb/products/lemme-smooth-capsules?variant=45597048111318">Lemme Smooth</a>, Kourtney Kardashian-Barker’s latest addition to her vitamin and supplement range. The product’s promotional materials claim that the capsule “visibly reduces cellulite in 28 days”. But what does the science tell us?</p> <p>Supplements like Lemme Smooth claim to improve skin texture and reduce cellulite from within. Kardashian-Barker’s supplement contains a mixture of <a href="https://link.springer.com/article/10.1007/s10298-015-0977-4">french cantaloupe melon</a>, hyaluronic acid, chromium and vitamin C among other ingredients. The body’s ability to absorb and utilise these ingredients in a way that would impact cellulite is still a subject of debate.</p> <p>There is evidence that <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4110621/#:%7E:text=In%20a%20randomized%2C%20double%2Dblind,in%20part%2C%20to%20the%20skin.">ingested hyaluronic acid</a> can migrate into the skin, stimulating the production of collagens within the dermis – and vitamin C has been shown to <a href="https://www.nature.com/articles/s41598-020-72704-1">thicken the surface layer</a> of the skin. However, the lack of standardisation in testing for the use of these ingredients in the treatment of cellulite means it’s still not clear if they will have a <a href="https://onlinelibrary.wiley.com/doi/10.1111/j.1467-2494.2006.00318.x">significant effect</a>.</p> <p>Other products marketed to reduce the appearance of cellulite include topical creams and lotions, containing ingredients like <a href="https://karger.com/books/book/763/chapter-abstract/5600478/Specific-Use-Cosmeceuticals-for-Body-Skin-Texture?redirectedFrom=fulltext">caffeine, retinol, and herbal extracts</a>. Cosmetic products are not able to penetrate the epidermis enough to significantly affect the underlying fat deposits and connective tissue.</p> <p>Some invasive treatments, such as <a href="https://www.aad.org/public/cosmetic/fat-removal/cellulite-treatments-what-really-works">laser therapy, subcision, and acoustic wave therapy</a> can offer more promising results. These procedures work by breaking down the connective tissue bands that cause dimpling and stimulating collagen production in the dermis to improve skin elasticity. While these methods <a href="https://www.aad.org/public/cosmetic/fat-removal/cellulite-treatments-what-really-works">may be more effective</a>, they are often expensive, require multiple sessions to achieve results – and aren’t without risk.</p> <p>Maintaining a healthy diet, drinking lots of water, and regular physical activity can help improve the overall appearance of the skin and reduce the visibility of cellulite. Losing weight and strengthening the muscles in the legs, buttocks and abdomen may make cellulite less noticeable, but it won’t make it <a href="https://jndc-chemistryarticles.info/ijn/article/318">disappear altogether</a>.</p> <p>The bottom line, though, is that cellulite does not need to be treated. It’s a normal anatomical variation that’s been transformed into a condition driving a lucrative market for cures <a href="https://link.springer.com/article/10.1007/s40257-015-0129-5">that don’t exist</a>.</p> <p>My top expert advice in the run up to summer?

Want to reduce your dementia risk? Eat these 4 foods, says new study

<p>If you are what you eat, this might make you hungrier for foods that are bright in every sense. Research has shown that living, vibrant foods can slow down aging at a cellular level; while fruit and vegetables in particular have been associated with lower incidence of cognitive decline as individuals age.</p> <p>However, research has been relatively lacking on just how much of these brain-healthy foods you really need and which fruit and vegetables are best for the job.</p> <p>In collaboration with public health experts at Harvard University, medical researchers at China’s Zhejiang University School of Medicine conducted a meta-analysis that’s slated to be published in the June 2024 issue of <em>The Journal of Nutrition, Health, and Aging</em>. They combined data from two large-scale population-representative studies that analysed the diets and cognitive function of more than 10,000 participants ages 55 and older from China and the US.</p> <h2>What daily diets revealed</h2> <p>The data included diet questionnaires that honed in on the average of participants’ total daily intake of several different types of foods, including fruit and vegetables, and also broke them down into sub-types like green leafy vegetables and berries. Over a period of five years, the participants also took part in activities designed to assess their cognitive function and the average rate of cognitive decline.</p> <p>Overall, participants who included the most fruit and vegetables in their daily diets performed best on the brain tests and maintained those results over time. This suggested that both fruit and vegetables had protective elements that slowed cognitive decline.</p> <h2>Vegetables that help protect cognition</h2> <p>Interestingly, certain types of vegetables appeared to be more beneficial than others—say the researchers: “Our findings support the potential beneficial roles of VF, especially cruciferous vegetables, green leafy vegetables, and red and yellow vegetables, in maintaining cognitive function and slowing cognitive decline in middle-aged and older adults.”</p> <p>The researchers pointed to several reasons these particular vegetables might have shown a substantial impact, including anti-inflammatory and antioxidation nutrients like flavonoids and various vitamins or even gut improvements that have been shown to help improve or protect cognition.</p> <p>While beans didn’t figure prominently in both studies, they showed a protective element in the US study, so they are also worth keeping on your plate. (Beans are also thought to be one of the top foods for longevity.)</p> <h2>Fruit that pack a punch</h2> <p>As for fruit, while some didn’t show as much of a protective effect across the board, berries and apples are two examples of fruit that experts have previously said provide major polyphenol and antioxidant effect.</p> <p>Participants whose brains maintained performance were shown to have eaten three or more servings of vegetables and two or more servings of fruit per day. This is on par with the five servings of vegetables and two servings of fruit recommended we eat every day.</p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.co.nz/healthsmart/want-to-reduce-your-dementia-risk-eat-these-4-foods-says-new-study" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

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

<p><em><a href="https://theconversation.com/profiles/fuschia-sirois-331254">Fuschia Sirois</a>, <a href="https://theconversation.com/institutions/durham-university-867">Durham University</a></em></p> <p>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.</p> <p>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.</p> <p>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.</p> <p>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.</p> <p>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.</p> <p>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.</p> <h2>The fountain of youth?</h2> <p>So why is it that optimists live longer? At first glance it would seem that it may have to do with their healthier lifestyle.</p> <p>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.</p> <p>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.</p> <p>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.</p> <p>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.</p> <h2>Looking on the bright side</h2> <p>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>.</p> <p>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.</p> <p>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.</p> <p>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" /></p> <p><em><a href="https://theconversation.com/profiles/fuschia-sirois-331254">Fuschia Sirois</a>, Professor in Social &amp; Health Psychology, <a href="https://theconversation.com/institutions/durham-university-867">Durham University</a></em></p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

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

<p><em><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></em></p> <p>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.</p> <p>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?</p> <p>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.</p> <p>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.</p> <p>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.</p> <p>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.</p> <p>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.</p> <figure><iframe src="https://www.youtube.com/embed/HloqayQdR6M?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>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.</p> <p>Some noted the feeling of guilt, which is perhaps something we’ve all felt after one too many Dairy Milks.</p> <h2>Health benefits of cocoa</h2> <p>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.</p> <p>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.</p> <p>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.</p> <figure><iframe src="https://www.youtube.com/embed/8VUcPCbSSCY?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>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.</p> <p>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>.</p> <h2>Chocolate toxicity</h2> <p>As much as chocolate might be considered a medicine for some, it can be a poison for others.</p> <p>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.</p> <p>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.</p> <p>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>.</p> <p>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.</p> <p>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.</p> <p>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.</p> <p>But whatever chocolate you go for, please don’t share it with the dog.<!-- Below is The Conversation's page counter tag.

Does the royal family have a right to privacy? What the law says

<p><em><a href="https://theconversation.com/profiles/gemma-horton-1515949">Gemma Horton</a>, <a href="https://theconversation.com/institutions/university-of-sheffield-1147">University of Sheffield</a></em></p> <p>From court cases to conspiracy theories, the royal family’s right to privacy is, somewhat ironically, nearly always in the spotlight. The latest focus is Kate Middleton, Princess of Wales, whose whereabouts have been the subject of <a href="https://www.townandcountrymag.com/society/tradition/a60008117/kate-middleton-health-speculation-conspiracy-theories-online/">online speculation</a> after it was announced she was undergoing abdominal surgery and would be away from public duties until after Easter.</p> <p>This comes just weeks after King Charles <a href="https://www.bbc.co.uk/news/uk-68208157">revealed that he is undergoing treatment for cancer</a>, and a legal settlement between Prince Harry and Mirror Group Newspapers over <a href="https://www.bbc.co.uk/news/uk-68249009">illegal phone hacking</a>.</p> <p>Interest in the personal lives of the royals and other celebrities <a href="https://www.tandfonline.com/doi/full/10.1080/1461670X.2016.1150193">is a constant</a>, driving newspaper sales and online clicks for decades. You only needs to consider the media frenzy that followed Princess Diana to <a href="https://www.tandfonline.com/doi/full/10.1080/17512786.2013.833678">see this</a>, and its potentially devastating consequences.</p> <p>From a legal perspective, the British courts have ruled that everyone – the royal family included – is entitled to a right to privacy. The Human Rights Act incorporates into British law the rights set out by the European Convention on Human Rights. This includes article 8, which focuses on the right to privacy.</p> <p>In the years after the Human Rights Act came into force, courts ruled on a string of cases from celebrities claiming that the press invaded their privacy. Courts had to balance article 8 of the convention against article 10, the right to freedom of expression.</p> <p>Rulings repeatedly stated that, despite being in and sometimes seeking the limelight, celebrities should still be afforded a right to privacy. Some disagree with this position, such as prominent journalist <a href="https://www.independent.co.uk/news/uk/home-news/prince-harry-hacking-piers-morgan-b2336442.html">Piers Morgan, who has criticised</a> the Duke and Duchess of Sussex asking for privacy when they have also released a Netflix documentary, a broadcast interview with Oprah Winfrey and published a memoir.</p> <p>But the courts have made the position clear, as in the case concerning Catherine Zeta-Jones and Michael Douglas after Hello! Magazine published unauthorised photographs from their wedding. The <a href="https://eprints.whiterose.ac.uk/190559/3/Final%20Edited%20Version%20-%20Celebrity%20Privacy%20and%20Celebrity%20Journalism-%20Has%20anything%20changed%20since%20the%20Leveson%20Inquiry_.pdf">court stated</a> that: “To hold that those who have sought any publicity lose all protection would be to repeal article 8’s application to very many of those who are likely to need it.”</p> <p>There is no universal definition of privacy, but scholars have identified key concepts encompassing what privacy can entail. In my own research, I have argued that the <a href="https://eprints.whiterose.ac.uk/190559/3/Final%20Edited%20Version%20-%20Celebrity%20Privacy%20and%20Celebrity%20Journalism-%20Has%20anything%20changed%20since%20the%20Leveson%20Inquiry_.pdf">notion of choice</a> is one of these. Privacy allows us to control the spread of information about ourselves and disclose information to whom we want.</p> <h2>Privacy and the public interest</h2> <p>There are exceptions to these protections if the person involved had no reasonable expectation of privacy, or if it was in the public interest for this information to be revealed. There is no solid, legal definition of the “public interest”, so this is decided on a case-by-case basis.</p> <p><a href="https://www.tandfonline.com/doi/full/10.1080/17577632.2021.1889866">In the past</a>, the public interest defence has been applied because a public figure or official has acted hypocritically and the courts have stated there is a right for a publisher to set the record straight.</p> <p>When it comes to medical records and information concerning health, case law and journalistic <a href="https://www.ipso.co.uk/editors-code-of-practice/">editorial codes of conduct</a> are clear that this information is afforded the utmost protection.</p> <p>Model Naomi Campbell was pictured leaving a Narcotics Anonymous meeting and these images were published by the Daily Mirror. The court found that there had been a public interest in revealing the fact she was attending these meetings, as she had previously denied substance abuse.</p> <p>The House of Lords accepted that there was a public interest in the press “setting the record straight”. Nonetheless, the publication of additional, confidential details, and the photographs of her leaving the meeting were a <a href="https://www.theguardian.com/media/2004/may/06/mirror.pressandpublishing1">step too far</a>. The House of Lords highlighted the importance of being able to keep medical records and information private.</p> <h2>Royal health</h2> <p>When it comes to the royals, the history of <a href="https://www.townandcountrymag.com/society/tradition/a23798094/lindo-wing-st-marys-hospital-facts-photos/">publicity</a> around royal births, often posing with the newborn royal baby outside of the hospital, has set a precedent for what the public can expect about the royals’ medical information. When they choose to go against this tradition, it can frustrate both royal-watchers and publishers.</p> <p>King Charles made the choice to openly speak about his enlarged prostate to “assist public understanding”. And, as Prostate Cancer UK noted, this has worked – they noted a <a href="https://www.independent.co.uk/news/uk/home-news/king-charles-cancer-statement-treatment-b2494190.html">500% increase in people visiting their website</a>. However, he has chosen to not to divulge information about his cancer diagnosis beyond the fact that he is receiving treatment. This is his right.</p> <p>While revealing further information might stop speculation and rumours about his health, it is not the king’s duty to divulge private, medical information. However, if his health begins to impact his ability to act as monarch, the situation could change.</p> <p>It might be that the press finds more information about his health without his knowledge, but unless they have a genuine public interest in publishing this information, privacy should prevail.</p> <p>You would no doubt want your private medical information kept secret, not shared around your workplace and speculated on unless it was absolutely necessary. It is thanks to these laws and court precedent that you don’t have to worry about this. The royal family, regardless of their position, should expect the same standard.</p> <p><a href="https://theconversation.com/profiles/gemma-horton-1515949"><em>Gemma Horton</em></a><em>, Impact Fellow for Centre for Freedom of the Media, <a href="https://theconversation.com/institutions/university-of-sheffield-1147">University of Sheffield</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Should Taylor Swift be taught alongside Shakespeare? A professor of literature says yes

<p><em><a href="https://theconversation.com/profiles/liam-e-semler-1507004">Liam E Semler</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>Does Taylor Swift’s music belong in the English classroom? No, obviously. We should teach the classics, like <a href="https://www.folger.edu/explore/shakespeares-works/shakespeares-sonnets/">Shakespeare’s Sonnets</a>. After all, they have stood the test of time. It’s 2024 and he was born in 1564, and she’s only 34. What’s more, she is a pop singer, not a poet. Sliding her into the classroom would be yet another example of a dumbed-down curriculum. It’s ridiculous. It makes everyone look bad.</p> <p>I’ve heard all that. And plenty more like it. But none of it is right. Well, the dates might be, but not the assumptions – about Shakespeare, about English, about teaching, and about Swift.</p> <p>Swift is, by the way, a poet. She sees herself this way and her songs bear her out. In Sweet Nothing, on the <a href="https://pitchfork.com/reviews/albums/taylor-swift-midnights/">Midnights</a> album, she sings:</p> <blockquote> <p>On the way home<br />I wrote a poem<br />You say “What a mind”<br />This happens all the time.</p> </blockquote> <p>I’m sure it does. Swift is relentlessly productive as a songwriter. With Midnights, she picked up <a href="https://edition.cnn.com/2024/02/04/entertainment/taylor-swift-album-of-the-year-grammys/index.html">her fourth Grammy for Album of the Year</a>. And here we are, on the brink of another studio album, <a href="https://en.wikipedia.org/wiki/The_Tortured_Poets_Department">The Tortured Poets Department</a>, somehow written and produced amid the gargantuan success of Midnights and the Eras World Tour.</p> <h2>An ally of literature</h2> <p>Regardless of what The Tortured Poets Department ends up being about, Swift is already a firm ally of literature and reading. She is <a href="https://www.cbsnews.com/news/taylor-swift-donates-6000-books-to-library/">a donor of thousands of books</a> to public libraries in the United States, an advocate to schoolchildren of the importance of reading and songwriting, and a lover of the process of crafting lyrics.</p> <p>In a <a href="https://www.youtube.com/watch?v=XnbCSboujF4">2016 Vogue interview</a>, Swift declared with glee that, if she were a teacher, she would teach English. The literary references in her songs are endlessly noted. “I love Shakespeare as much as the next girl,” she wrote in a <a href="https://www.elle.com/uk/life-and-culture/a26546099/taylor-swift-pop-music/">2019 article for Elle</a>.</p> <figure><iframe src="https://www.youtube.com/embed/mdgKhdcQrNw?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>Her interview Read Every Day gives a good sense of this. Swift speaks about her writing process in ways that make it accessible. She explains how songs come to her anywhere and everywhere, like an idea randomly appearing “on a cloud” that becomes the first piece in a “puzzle” that will be assembled into a song. She furtively whisper-sings song ideas into her phone when out with friends.</p> <p>In her <a href="https://www.thelineofbestfit.com/news/read-taylor-swifts-full-nsai-songwriter-artist-of-the-decade-award-speech">acceptance speech for the Nashville Songwriter-Artist of the Decade Award</a> in 2022, Swift explained how she writes in three broad styles, imagining she is holding either a “quill”, a “fountain pen”, or a “glitter gel pen”. Songcraft is a joyous challenge for her.</p> <p>If, as teachers of literature, we are too proud to credit Swift’s plainly expressed love of English (regardless of whether we like her songs or not), we are likely missing something. To bluntly rule her out of the English classroom feels more absurd than allowing her in.</p> <p>Clio Doyle, a lecturer in early modern literature, has <a href="https://theconversation.com/why-taylor-swift-belongs-on-english-literature-degree-courses-219660">summarised</a> Swift’s suitability for English in a recent article which concludes:</p> <blockquote> <p>The important thing isn’t whether or not Swift might be the new Shakespeare. It’s that the discipline of English literature is flexible, capacious and open-minded. A class on reading Swift’s work as literature is just another English class, because every English class requires grappling with the idea of reading anything as literature. Even Shakespeare.</p> </blockquote> <p>Doyle reminds us Swift’s work has been taught at universities for a while now and, inevitably, the singer’s name keeps cropping up in relation to Shakespeare. This isn’t just a case of fandom gone wild or Shakespeare professors, like <a href="https://www.smh.com.au/culture/music/why-taylor-swift-is-a-literary-giant-by-a-shakespeare-professor-20230518-p5d9cn.html">Jonathan Bate</a>, gone rogue.</p> <p>The global interest in the world-first academic <a href="https://swiftposium2024.com/">Swiftposium</a> is a good measure of how things are trending. Moreover, it is wrong to think Swift’s songs are included in units of study purely to be adored. Her wide appeal is part of her appeal to educators, but that doesn’t mean her art is uncritically included.</p> <p>The reverse is true. Claire Hansen <a href="https://www.smh.com.au/national/pop-star-philosopher-poet-taylor-swift-is-shaking-up-how-we-think-20240207-p5f342.html">taught Swift in one of her literature units at the Australian National University</a> last year precisely because this influential singer-songwriter prompts students to explore the boundaries of the canon.</p> <p>I will be teaching Midnights and Shakespeare’s Sonnets together in a literature unit at the University of Sydney this semester. Why? Not because I think Swift is as good as Shakespeare, or because I think she is not as good as Shakespeare. These statements are fine as personal opinions, but unhelpful as blanket declarations without context. The nature of English as a discipline is far more complex, interesting and valuable than a labelling and ranking exercise.</p> <h2>Teaching Midnights and Shakespeare’s Sonnets</h2> <p>I teach Shakespeare’s sonnets as exquisite poems, reflective of their time and culture. I also teach three modern artworks that shed contemporary light on the sonnets.</p> <p>The first is Jen Bervin’s 2004 book <a href="https://www.jenbervin.com/projects/nets">Nets</a>. Bervin prints a selection of the sonnets, one per page, in grey text. In each of these grey sonnets, some of Shakespeare’s words and phrases are printed in black and thus stand out boldly.</p> <p>The result is a <a href="https://dictionary.cambridge.org/dictionary/english/palimpsest">palimpsest</a>. The Shakespearean sonnet appears lying, like fertile soil, beneath the briefer poem that emerges from it. Bervin describes this technique as a stripping down of the sonnets to “nets” in order “to make the space of the poems open, porous, possible – a divergent elsewhere”. The creative relationship between the Shakespearean base and Bervin’s proverb-like poems proves that, as Bervin says, “when we write poems, the history of poetry is with us”.</p> <p>The second text is Luke Kennard’s prizewinning 2021 collection <a href="https://www.pennedinthemargins.co.uk/index.php/2021/04/notes-on-the-sonnets/">Notes on the Sonnets</a>. Kennard recasts the sonnets as a series of entertaining prose poems. Each poem responds to a specific Shakespearean sonnet, recasting it as the freewheeling thought bubble of a fictional attendee at an unappealing house party. In an interview with C.D. Rose, Kennard <a href="https://thequietus.com/articles/30078-luke-kennard-interview-the-answer-to-everything-notes-on-the-sonnets">explains</a> how his house party design puts the reader</p> <blockquote> <p>in between a public and private space, you’re at home and you’re out, you’re free, you’re enclosed. And that’s similar in the sonnets.</p> </blockquote> <p>The third text is Swift’s Midnights. Unlike Bervin’s and Kennard’s collections, in which individual pieces relate to specific sonnets, there is no explicit adaptation. Instead, Midnights raises broader themes.</p> <h2>Deep connection</h2> <p>In her Elle article, Swift describes songwriting as akin to photography. She strives to capture moments of lived experience:</p> <blockquote> <p>The fun challenge of writing a pop song is squeezing those evocative details into the catchiest melody you can possibly think of. I thrive on the challenge of sprinkling personal mementos and shreds of reality into a genre of music that is universally known for being, well, universal.</p> </blockquote> <p>Her point is that the pop songs that “cut through the most are actually the most detailed” in their snippets of reality and biography. She says “people are reaching out for connection and comfort” and “music lovers want some biographical glimpse into the world of our narrator, a hole in the emotional walls people put up around themselves to survive”.</p> <p>Midnights exemplifies this. It is a concept album built on the idea that midnight is a time for pursuit of and confrontation with the self – or better, the selves. Swift says the songs form “the full picture of the intensities of that mystifying, mad hour”.</p> <p>The album, she says, is “a journey through terrors and sweet dreams” for those “who have tossed and turned and decided to keep the lanterns lit and go searching – hoping that just maybe, when the clock strikes twelve […] we’ll meet ourselves”.<br />Swift claims that Midnights lets listeners in through her protective walls to enable deep connection:</p> <blockquote> <p>I really don’t think I’ve delved this far into my insecurities in this detail before. I struggle with the idea that my life has become unmanageably sized and […] I just struggle with the idea of not feeling like a person.</p> </blockquote> <p>Midnights is not a sonnet collection, but it has fascinating parallels. There is no firm narrative through-line. Nor is there a through-line in early modern sonnet collections such as Shakespeare’s. Instead, both gather songs and poems that let us see aspects of the singing or speaking persona’s thoughts, emotions and experiences. Shakespeare’s speaker is also troubled through the night in sonnets 27, 43 and 61.</p> <p>The sonnets come in thematic clusters, pairs and mini-sequences. It can be interesting to ask students if they can see something similar in the order of songs on the Midnights album – or the “3am” edition with its seven extra tracks, or the “Til Dawn” edition with another three songs.</p> <p>Paul Edmondson and Stanley Wells, in their edition of <a href="https://www.cambridge.org/core/books/all-the-sonnets-of-shakespeare/AE1912C43BE4F50391B25B83C0C03B1F">All the Sonnets of Shakespeare</a>, say Shakespeare’s collection is “the most idiosyncratic gathering of sonnets in the period” because he “uses the sonnet form to work out his intimate thoughts and feelings”.</p> <p>This connects very well with the agenda of Midnights. Both collections are piecemeal psychic landscapes. The singing or speaking voice sometimes feels autobiographical – compare, for example, sonnets 23, 129, 135-6 and 145 to Swift’s songs Anti-hero, You’re On Your Own, Kid, Sweet Nothing, and Would’ve, Could’ve, Should’ve. At other times the voices feel less autobiographical. Often there is no way to distinguish one from the other.</p> <p>Swift’s songs and Shakespeare’s Sonnets are meditations on deeply personal aspects of their narrators’ experiences. They present us with encounters, memories, relationships, values and claims. Swift’s persona is that of a self-reflective singer, just as Shakespeare’s is that of a self-reflective sonneteer. Both focus on love in all its shades. Both present themselves as vulnerable to industry rivals and pressures. Both dwell on issues of power.</p> <h2>Close reading</h2> <p>Shakespeare’s sonnets are rewarding texts for close reading because of their poetic intricacy. Students can look at end rhymes and internal rhymes, the way the argument progresses through <a href="https://www.poetryfoundation.org/learn/glossary-terms/quatrain">quatrains</a>, the positioning of the “turn”, which is often in line 9 or 13, and the way the final couplet wraps things up (or doesn’t).</p> <p>The songs on Midnights are also rewarding because Swift has a great vocabulary, a love of metaphor, terrific turns of phrase, and a strong sense of symmetry and balance in wording. More complex songs like Maroon and Question…? are great for detailed analysis.</p> <p>Karma and Mastermind are simpler, yet contain plenty of metaphoric language to be unpacked for meaning and aesthetic effectiveness. Shakespeare’s controlled use of metaphor in Sonnet 73 makes for a telling contrast.</p> <p>The Great War, Glitch and Snow on the Beach are good for exploring how well a single extended metaphor can function to carry the meaning of a song. Sonnets 8, 18, 143 and 147 can be explored in similar terms.</p> <p>Just as students can analyse the “turn” or concluding couplet in a Shakespearean sonnet to see how it reshapes the poem, they can do the same with songs on Midnights. Swift is known for writing effective bridges that contribute fresh, important content towards the end of a song: Sweet Nothing, Mastermind and Dear Reader are excellent examples.</p> <p>Such unexpected pairings are valuable because they require close attention and careful articulation of what is similar and what is not. Shakespeare’s Sonnet 129, for example (the famous one on lust), and Swift’s Bigger than the Whole Sky (a powerful expression of loss) make for a gripping comparison of how intense feeling can be expressed poetically.</p> <p>Or consider Sonnet 29 (“When in disgrace with fortune and men’s eyes”) and Sweet Nothing: both celebrate intimacy as a defence against the pressures of the public world. How about High Infidelity and Sonnet 138 (where love and self-deception coexist), considered in terms of truth in relationships?</p> <p>There is nothing to lose and plenty to gain in teaching Swift’s Midnights and Shakespeare’s Sonnets together. There’s no dumbing-down involved. And there’s no need for reductive assertions about who is “better”.<!-- Below is The Conversation's page counter tag.

Your skin is a mirror of your health – here’s what yours might be saying

<p><em><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></em></p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/12095893/">Skin accounts for around 15% of our body mass</a>. It is the largest and most visible organ in the human body.</p> <p>Yet many of the skin’s functions are often overlooked. It’s a sunscreen, a shield from germs, a reservoir of <a href="https://pubmed.ncbi.nlm.nih.gov/28994020/">vitamin D</a> and a means of tightly regulating our body temperature.</p> <p>Being the most visible of our organs, the skin also offers us a view into the body tissues that it protects. So don’t think of your skin merely aesthetically – think of it as a reflection of your health. Disorders of the gut, blood, hormones and even the heart might first be seen on the skin in the form of a rash.</p> <p>Here are a few to look out for.</p> <h2>Bullseye</h2> <p>Ticks are pesky creatures that no one will want to return home from a country walk with.</p> <p>But while the vast majority of tick bites <a href="https://pubmed.ncbi.nlm.nih.gov/36116831/">won’t make you ill</a>, there is one rash that should prompt a visit to your doctor if you spot it.</p> <p>Erythema migrans, a rash named for its ability to rapidly expand across the skin, is a hallmark of <a href="https://www.bmj.com/content/369/bmj.m1041.long">Lyme disease</a>, a potentially severe bacterial illness. This rash forms a classic target pattern, like a bullseye on a dartboard.</p> <p>Be vigilant for a few weeks after being bitten to check this rash doesn’t make an appearance – especially if you noticed a red lump that wasn’t there before or if you had to remove a tick from your skin. You should also keep an eye out for other associated symptoms of Lyme disease – such as swinging temperatures, muscle and joint pains and headache.</p> <p>The condition is treated with antibiotics, which can prevent long-term complications, including chronic fatigue symptoms.</p> <h2>Purpura</h2> <p>Some rashes are given a <a href="https://linkinghub.elsevier.com/retrieve/pii/S1538-7836(22)01880-3">colourful namesake</a> – purpura is one such example. This rash’s name is derived from a mollusc which was used to make purple dye.</p> <p>Purpura refers to a rash of small purple or red dots. The cause is pooling of blood into a deeper layer of the skin (dermis). When pressed with a finger – or even better, the side of a glass – it refuses to blanch away.</p> <p>Purpura signals an issue with either the walls of the tiny blood vessels that feed the skin or the blood within them. This might be from a deficiency in platelets, the tiny cell fragments that allow blood to clot – perhaps from bone marrow failure, or an autoimmune condition where the body turns on itself and attacks its own cells.</p> <p>At worst, purpura may signal the life-threatening condition <a href="https://www.magonlinelibrary.com/doi/full/10.12968/hmed.2017.78.8.468">septicaemia</a>, where an infection has spread into the bloodstream – perhaps from the lungs, kidneys or even from the skin itself.</p> <h2>Skin spiders</h2> <p>Skin rashes can also take on <a href="https://pubmed.ncbi.nlm.nih.gov/32513406/">recognisable shapes</a>.</p> <p>Spider naevi represent an issue within skin arterioles (small arteries which supply the skin with blood). Arterioles open and close to control the loss of heat from the body’s surface. But sometimes they can get stuck open – and a spider-like pattern will appear.</p> <p>The open arteriole is the spider’s body, and the even tinier capillaries fanning out in all directions are the thready legs. Crush the body under a fingertip and the whole thing disappears, as your touch temporarily stops the blood flow.</p> <p>Often, these are benign and not associated with any specific condition – especially if you only have one or two. However, more than three suggest higher circulating levels of the <a href="https://dermnetnz.org/topics/spider-telangiectasis">hormone oestrogen</a>, often due to liver disease or from the hormonal changes seen in pregnancy. Treat the underlying cause, and the spiders often vanish with time – though they may persist or reappear later.</p> <h2>Black velvet</h2> <p>Changes to the folds of your skin (usually around the armpits or neck) – especially if it becomes thickened and velveteen to the touch – may suggest a condition known as <a href="https://onlinelibrary.wiley.com/doi/10.1111/jocd.13544">acanthosis nigricans</a>. This “black velvet” skin appearance is more commonly seen in darker skins.</p> <p>Usually, the condition is associated with <a href="https://pubmed.ncbi.nlm.nih.gov/29241752/">disorders of the metabolism</a> – namely type 2 diabetes and polycystic ovary syndrome. If either of these conditions are successfully treated, the rash may fade. In rare cases, it can also be a sign of <a href="https://www.hkmj.org/abstracts/v29n4/355.htm">stomach cancer</a>, which should be considered in patients with few or none of the key signs of metabolic disease (obesity and high blood pressure).</p> <h2>Butterfly rashes</h2> <p>Even disorders of the heart can be visible on the skin.</p> <p>Cardiac valves have the important role of correctly directing the journey of blood through the heart and preventing backflow. The valve between the chambers on the left side of the heart (the mitral valve – so called because of its resemblance to a bishop’s hat, or mitre) can sometimes become narrowed, causing the heart’s function to deteriorate. The body’s natural response is to preserve core blood volume, shutting off flow towards the skin.</p> <p>The net effect can produce a purple-red rash, high across the cheeks and the bridge of the nose, like the outstretched wings of a butterfly. We call this <a href="https://journals.sagepub.com/doi/10.1177/2050313X231200965?url_ver=Z39.88-2003&amp;rfr_id=ori:rid:crossref.org&amp;rfr_dat=cr_pub%20%200pubmed">mitral facies</a> which, depending on the extent of damage to the heart and great vessels, may persist despite treatment.</p> <p>It’s important to pay heed to your skin. It’s constantly talking to you, and any changes in its texture, colour or if new marks or patterns appear, may indicate something is going on beneath the surface.<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/221937/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><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></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

7 things you should never say at a funeral

<p><strong>What not to say at a funeral </strong></p> <p>Struggling to find the right words to convey sympathy at a funeral? Even the most well-intentioned comments can come across as hurtful instead of helpful. Here are some common phrases you should never say at a funeral –and what to say instead.</p> <p><strong>Never say "I know how you feel" at a funeral </strong></p> <p><span style="text-decoration: underline;"><em>Instead, say:</em></span> “I can’t imagine how you feel.”</p> <p>By the time we’re adults, most of us will have experienced the loss of a family member, friend or colleague. What’s important to note, however, is that although the phases of grief are similar, we don’t necessarily know how another grieving individual truly feels. “Everyone’s experience is unique,” says Jaime Bickerton, executive director of Bereaved Families of Ontario in Canada. “Everyone’s loss is the worst, because it’s theirs.”</p> <p>It can help to think of yourself in a helper role, says author and grief counsellor, Dr Alan Wolfelt. “Walk ‘with,’ not ‘behind’ or ‘in front of’ the person who is mourning.”</p> <p><strong>"Time heals all wounds" is something you should never say at a funeral </strong></p> <p><span style="text-decoration: underline;"><em>Instead, say:</em></span> “Take the time you need and be gentle with yourself.”</p> <p>“There’s no formula when it comes to grief,” says Asya Hadzismajlovic, bereavement expert. “It comes in waves.” The grieving process takes time and important dates like anniversaries and birthdays can trigger an emotional tsunami. Allow the bereaved to move through that process at his or her own pace, advises Wolfelt. “Don’t force your timetable for healing. Allow them to experience all the hurt, sorrow and pain he or she is feeling at the time.”</p> <p><strong>Never say “At least he didn’t suffer,” “At least she made it to her birthday,” or “At least she died doing what she loved” at a funeral</strong></p> <p><span style="text-decoration: underline;"><em>Instead, say:</em></span> “I am here for you.”</p> <p>It’s best to avoid any statements that begin with “at least,” notes Bickerton. These sentiments are often an attempt to make dark days more bearable, but they won’t diminish the pain of losing a loved one. What the person grieving really needs is your quiet presence, says Hadzismajlovic. Check in during the day of the funeral and beyond. “People just want to be heard; to be listened to,” she says. “We say that grief shared is grief lessened.”</p> <p><strong>“Let me know what I can do” is something you should never say at a funeral</strong></p> <p><span style="text-decoration: underline;"><em>Instead, say:</em></span> “Here’s what I can do for you…”</p> <p>This comment places the burden on the bereaved to reach out for help at a time when they likely don’t know what they need, explains Bickerton. Running a few loads of their laundry, tidying their house or yard and preparing meals are just a few ways to genuinely show you care as opposed to merely saying you care. “If they have 38 casseroles, make the 39th,” says Wolfelt. “Deliver it in your best dish and say you will be over in a week to pick it up. This provides you with an opportunity to check in.”</p> <p><strong>Never say “She’s in a better place” at a funeral</strong></p> <p><span style="text-decoration: underline;"><em>Instead, say:</em></span> “She will be missed.”</p> <p>“Most likely, the person grieving is thinking the best place for [the deceased] to be is with them,” says Bickerton. “There’s also a danger of assuming the person ascribes to certain beliefs, which may not be the case.” Simply show your support for your grieving friend, colleague or family member, advises Wolfelt. “At the funeral, a touch of your hand, a look in your eye or even a hug often communicates more than words can say.”</p> <p><strong>Never say “It was his time” at a funeral</strong></p> <p><span style="text-decoration: underline;"><em>Instead, say:</em></span> “I am so sorry for the loss of your precious [person’s name].”</p> <p>“This platitude can be particularly upsetting for the grieving person to hear as it implies a reason for the death when they may be feeling the death was senseless or irrational,” says Bickerton. Even if the loved one lived a long, full life, the person grieving would likely have been wishing for many more years together. When expressing your condolence be sure to say the person’s name, advises Wolfelt. “That way the person grieving knows you are genuinely concerned.”</p> <p><strong>Never say “You need to say goodbye” or “Life must go on” at a funeral</strong></p> <p><span style="text-decoration: underline;"><em>Instead, say:</em></span> “He will always be remembered for his generosity/love for his family…”</p> <p>Statements like these tend to minimise the grief journey, says Bickerton. “Life will go on but it will look very different for the person grieving as they adjust to their new normal.” A note that shares a favourite memory or relates the special qualities you valued in the person who has passed is a thoughtful way to express your condolences before or after the funeral, says Wolfelt. “These words will often be a loving gift to the grieving person.”</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.co.nz/true-stories-lifestyle/relationships/7-things-you-should-never-say-at-a-funeral" target="_blank" rel="noopener">Reader's Digest</a>.</em></p>

"It is hard to say": News anchor announces health news during broadcast

Can coffee help you avoid weight gain? Here’s what the science says

<p><em><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></em></p> <p>Coffee is well recognised as having a positive impact on long-term health. Drinking the equivalent of three to four cups of instant coffee a day <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5696634/">reduces the risk</a> of many health conditions including heart disease, type 2 diabetes and some cancers.</p> <p>Most people gain <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4984841/">small amounts of weight</a> each year as they age. But can coffee help prevent this gradual weight gain?</p> <p>A group of researchers examined whether drinking an extra cup of coffee a day – or adding sugar, cream or a non-dairy alternative – resulted in more or less weight gain than those who didn’t adjust their intake.</p> <p>Their <a href="https://www.sciencedirect.com/science/article/abs/pii/S0002916523661702">research</a> (currently a pre-proof, which means it has been peer reviewed but is yet to undergo the final formatting and copyediting) found a modest link between coffee and gaining less weight than expected.</p> <p>People who drank an extra cup of coffee a day gained 0.12 kg less weight than expected over four years. Adding sugar resulted in a fraction more (0.09 kg) weight gain than expected over four years.</p> <h2>How was the study conducted? What did it find?</h2> <p>Researchers combined data from three large studies from the United States: two <a href="https://nurseshealthstudy.org">Nurses’ Health Studies</a> from 1986 to 2010, and from 1991 to 2015, and a <a href="https://www.hsph.harvard.edu/hpfs/about-the-study/">Health Professional Follow-up study</a> from 1991 to 2014.</p> <p>The Nurses’ Health Studies are two of the largest cohort studies, with more 230,000 participants, and investigates chronic disease risks for women. The Health Professional Follow-up study involves more than 50,000 male health professionals and investigates the relationship between diet and health outcomes.</p> <p>Participants in all three studies completed a baseline questionnaire, and another questionnaire every four years to assess their food and drink intake. Using the combined datasets, researchers analysed changes in coffee intake and changes in the participants’ self-reported weight at four-year intervals.</p> <p>The average four year weight-gains for the nurses’ studies were 1.2kg and 1.7kg, while participants in the health professionals study gained an average of 0.8kg.</p> <p>The researchers found that increasing unsweetened caffeinated or decaffeinated coffee intake by one cup a day was associated with a weight gain that was 0.12 kg less than expected over four years.</p> <p>Adding creamer (milk) or a non-dairy alternative did not significantly affect this weight change.</p> <p>However, adding sugar (one teaspoon) to coffee was associated with a weight gain that was 0.09 kg more than expected over four years.</p> <p>These associations were stronger in participants who were younger and had a higher body mass index at the beginning of the studies.</p> <h2>What are the pros and cons of the study?</h2> <p>This study is unique in two ways. It had a very large sample size and followed participants for many years. This adds confidence that the associations were real and can likely be applied to other populations.</p> <p>However, there are three reasons to be cautious.</p> <p>First, the findings represent an <em>association</em>, not <em>causation</em>. This means the study does not prove that coffee intake is the true reason for the weight change. Rather, it shows the two changes were observed together over time.</p> <p>Second, the findings around weight were very modest. The average four-year weight gain averted, based on one cup of coffee, was 0.12 kilograms, which is about 30 grams per year. This amount may not be a meaningful change for most people looking to manage weight.</p> <p>Finally, this analysis did not consider the variability in the amount of caffeine in coffee (which we <a href="https://pubmed.ncbi.nlm.nih.gov/17412475/">know can be high</a>), it just assumed a standard amount of caffeine per cup.</p> <h2>How could coffee help with weight management?</h2> <p>Caffeine is a natural stimulant which has been <a href="https://www.sciencedirect.com/science/article/pii/S0149763416300690">shown to</a> temporarily reduce appetite and increase alertness. This may help to feel less hungry for a short period, potentially leading to reduced energy intake.</p> <p>Some people consume coffee before exercise as a stimulant to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7777221/">improve their workout performance</a> – if a workout is more effective, more energy may be expended. However, the benefit is largely thought to be short-lived, rather than long-term.</p> <p>Caffeine has also been <a href="https://www.sciencedirect.com/science/article/pii/S0271531720304449">shown to</a> speed up our metabolism, causing more energy to be burned while resting. However, this effect is relatively small and is not a suitable substitute for regular physical activity and a healthy diet.</p> <p>Finally, coffee has a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4725310/">mild diuretic effect</a>, which can lead to temporary water weight loss. This is water loss, not fat loss, and the weight is quickly regained when you re-hydrate.</p> <h2>Is it worth trying coffee for weight loss?</h2> <p>Losing weight can be influenced by various factors, so don’t get too enthusiastic about the coffee-weight link highlighted in this new study, or increase your coffee intake to unreasonable levels.</p> <p>Most adults can safely consume around <a href="https://www.healthdirect.gov.au/caffeine">400mg</a> of caffeine a day. That’s the equivalent of two espressos or four cups of instant coffee or eight cups of tea.</p> <p>If you are pregnant or breastfeeding, it is important to talk to your doctor before increasing your caffeine intake, because caffeine can be passed through to your growing baby.</p> <p>If you need individualised weight guidance, talk to your GP or visit an <a href="https://member.dietitiansaustralia.org.au/Portal/Portal/Search-Directories/Find-a-Dietitian.aspx">accredited practising dietitian</a>. <img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/214954/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><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>, Dietitian, Researcher &amp; Lecturer, <a href="https://theconversation.com/institutions/southern-cross-university-1160">Southern Cross University</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

What your family history says about your eyesight

<p>Eye disorders can be caused by many things such as infection and injury but did you know it can also be genetic? We know looking up our family history is important for our health but it’s also vitally important to do so for our eyes. Genetics do play a role in determining your family’s susceptibility to certain eye diseases so it’s a good idea to check your family history as well as record any eye issues you have for future generations. </p> <p>Here are some of the most common hereditary eye conditions. </p> <p><strong>Glaucoma</strong></p> <p>Not all glaucoma is inherited but the most common type, primary open-angle glaucoma, is hereditary. According to the Glaucoma Research Foundation, a family history of glaucoma increases your risk around four to nine times. </p> <p>Coupled with the fact glaucoma is much more common as you age, it’s a good idea to get your eyes checked regularly. Glaucoma can lead to the reduction in peripheral vision and even blindness. Signs include bulging eyes, excessive tearing and abnormal sensitivity to light.</p> <p><strong>Age-related macular degeneration</strong></p> <p>Scientist have found that genetics may contribute to the risk of having macular degeneration but it’s not always the case. Some people never develop it even though both parents may have it while others get it even though there is no family history. The current research shows that genetics contribute to macular degeneration anywhere from 40 to 70 percent. </p> <p>However, whether you have a family history or not it’s important to get your eyes checked as age-related macular degeneration is the leading cause of vision loss in people aged 50 and over. </p> <p><strong>Colour blindness</strong></p> <p>A misnomer as people are not ‘blind’ but colour vision deficient. People who are colour blind usually cannot distinguish between certain colours such as red and green. Inherited colour blindness is common in men with women rarely affected. There is no treatment and most people adjust to the condition.</p> <p><strong>Retinitis pigmentosa</strong></p> <p>A mutated gene causes the retina to degenerate which can lead to night blindness and vision loss. Most cases are inherited and it usually appears in childhood but vision loss doesn’t occur until later in life. There is unfortunately no cure and no treatments but researchers are making significant progress in identifying the genes that cause retinitis pigmentosa.</p> <p><strong>Achromatopsia</strong></p> <p>An inherited condition (only if both parents have the recessive gene) that affects 1 in 33,000 people. The condition is associated with decreased vision, sensitivity to light and colour blindness.</p> <p><strong>Optic atrophy</strong></p> <p>Optic atrophy may be inherited or caused by brain trauma, inflammation, degenerative disorders, haemorrhage or tumour. The breakdown of the optic nerve causes vision loss. </p> <p><em>Image credits: Getty Images </em></p>

Kids dressing up as older people is harmless fun, right? No, it’s ageist, whatever Bluey says

<p><em><a href="https://theconversation.com/profiles/lisa-mitchell-1143692">Lisa Mitchell</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a></em></p> <p>A child once approached me, hunched over, carrying a vacuum cleaner like a walking stick. In a wobbly voice, he asked: "Do you want to play grannies?"</p> <p>The idea came from the children’s TV show Bluey, which <a href="https://www.facebook.com/ABCKidsCommunity/videos/bluey-grannies/468144817266668/">has</a> <a href="https://www.facebook.com/ABCKidsCommunity/videos/new-bluey-episodes-the-grannies-are-back-abc-kids/371436135028190/">episodes</a>, <a href="https://www.bluey.tv/products/grannies-book/">a book</a>, <a href="https://www.discountmags.com/magazine/bluey-september-1-2023-digital">magazine</a> editions and an <a href="https://www.facebook.com/OfficialBlueyTV/videos/grannies-filter-bluey/5728362390510269/">image filter</a> about dressing up as “grannies”.</p> <p>Children are also dressing up as 100-year-olds to mark their first “100 days of school”, an idea <a href="https://www.theage.com.au/national/victoria/old-people-s-home-for-five-year-olds-prep-students-don-senior-citizen-attire-20230801-p5dszb.html">gaining popularity</a> <a href="https://www.smh.com.au/education/cardigans-wigs-and-canes-why-kindy-students-are-dressing-up-as-100-year-olds-20230720-p5dpu8.html">in Australia</a>.</p> <p>Is this all just harmless fun?</p> <h2>How stereotypes take hold</h2> <p>When I look at the older people in my life, or the patients I see as a geriatrician, I cannot imagine how to suck out the individual to formulate a “look”.</p> <p>But Google “older person dress-ups” and you will find <a href="https://www.pinterest.com.au/pin/dress-up-like-youre-100-years-old-100thdayofschool--15199717464361356/">Pinterests</a> and <a href="https://www.wikihow.com/Dress-Up-Like-an-Old-Person#:%7E:text=Dress%20in%20comfortable%2C%20loose%2Dfitting,older%20people%20may%20wear%20include%3A&amp;text=Oversized%20sweatshirts">Wikihow pages</a> doing just that.</p> <p>Waistcoats, walking sticks, glasses and hunched backs are the key.

And if dressing up as an older person is an example, such stereotypes are all around us.</p> <h2>What’s the harm?</h2> <p>There is <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/hypa.12170">some debate</a> about whether stereotyping is intrinsically wrong, and if it is, why. But there is plenty of research about the harms of <em>age</em> stereotypes or ageism. That’s harm to current older people and harm to future older people.</p> <p>The World Health Organization <a href="https://www.who.int/health-topics/ageism#tab=tab_1">defines ageism</a> as: "the stereotypes (how we think), prejudice (how we feel) and discrimination (how we act) towards others or ourselves based on age."</p> <p>Ageism <a href="https://www.who.int/health-topics/ageism#tab=tab_1">contributes to</a> social isolation, reduced health and life expectancy and costs economies <a href="https://academic.oup.com/gerontologist/article/60/1/174/5166947">billions of dollars</a> globally.</p> <p>When it comes to health, the impact of negative stereotypes and beliefs about ageing may be even <a href="https://academic.oup.com/gerontologist/article/60/1/174/5166947">more harmful</a> than the discrimination itself.</p> <p>In laboratory studies, older people perform <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4360754/">worse</a> than expected on tasks such as memory or thinking after being shown negative stereotypes about ageing. This may be due to a “<a href="https://www.simplypsychology.org/stereotype-threat.html">stereotype threat</a>”. This is when a person’s performance is impaired because they are worried about confirming a negative stereotype about the group they belong to. In other words, they perform less well because they’re worried about acting “old”.</p> <p>Another theory is “stereotype embodiment”. This is where people absorb negative stereotypes throughout their life and come to believe decline is an inevitable consequence of ageing. This leads to biological, psychological and physiological changes that <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2927354/">create</a> a self-fulfilling prophecy.</p> <p>I have seen this in my clinic with people who do well, until they realise they’re an older person – a birthday, a fall, a revelation when they look in the mirror. Then, they stop going out, stop exercising, stop seeing their friends.</p> <p>Evidence for “stereotype embodiment” comes from studies that show people with more negative views about ageing are more likely to have higher levels of stress hormones (such as cortisol and C-reactive protein) and are <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7182003/">less likely</a> to engage in health behaviours, such as exercising and eating healthy foods.</p> <p>Younger adults with negative views about ageing are <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2666386/">more likely</a> to have a heart attack up to about 40 years later. People with the most negative attitudes towards ageing have a lower life expectancy by as much as <a href="https://pubmed.ncbi.nlm.nih.gov/12150226/">7.5 years</a>.</p> <p>Children are particularly susceptible to absorbing stereotypes, a process <a href="https://psycnet.apa.org/record/2007-09385-010">that starts</a> in early childhood.</p> <h2>Ageism is all around us</h2> <p><a href="https://www.who.int/health-topics/ageism#tab=tab_1">One in two people</a> have ageist views, so tackling ageism is complicated given it is socially acceptable and normalised.</p> <p>Think of all the birthday cards and jokes about ageing or phrases like “geezer” and “old duck”. Assuming a person (including yourself) is “too old” for something. Older people say it is harder to <a href="https://www.abc.net.au/news/2023-07-06/senior-job-seekers-struggle-to-get-a-foot-in-the-door/102563144">find work</a> and they face discrimination in <a href="https://www.hcnsw.org.au/wp-content/uploads/2021/03/Ageism-in-Health-Care_final.pdf">health care</a>.</p> <h2>How can we reduce ageism?</h2> <p>We can reduce ageism through laws, policies and education. But we can also reduce it via <a href="https://www.who.int/health-topics/ageism#tab=tab_1">intergenerational contact</a>, where older people and younger people come together. This helps break down the segregation that allows stereotypes to fester. Think of the TV series <a href="https://iview.abc.net.au/show/old-people-s-home-for-4-year-olds">Old People’s Home for 4 Year Olds</a> or the follow-up <a href="https://iview.abc.net.au/show/old-people-s-home-for-teenagers">Old People’s Home for Teenagers</a>. More simply, children can hang out with their older relatives, neighbours and friends.</p> <p>We can also challenge a negative view of ageing. What if we allowed kids to imagine their lives as grandparents and 100-year-olds as freely as they view their current selves? What would be the harm in that?<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/212607/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/lisa-mitchell-1143692"><em>Lisa Mitchell</em></a><em>, Geriatrician working in clinical practice.

What not to say when someone comes out as LGBTQ+ (and what to say instead)

<p><strong>"Are you sure?"</strong></p> <p>People who identify as LGBTQ+ often struggle a great deal with their own feelings before they make the nerve-wracking decision to come out. Despite your best intentions, responding to this by asking, “Are you sure?” may be seen as calling into question the emotional journey that brought them to that point. </p> <p>Instead of expressing what might be interpreted as doubt, you could perhaps say, “It’s always good to know what you like and want. Thanks for coming out to me.”</p> <p><strong>"It must have been tough for your parents"</strong></p> <p>Yes, it could have been tough for the parents. But guess what? It was harder on the individual for even longer – and in more intense ways than you can imagine. Staying in the closet is not a very comfortable position for a self-accepting person, but it’s an even harder journey to get to that point of self-acceptance. LGBTQ+ individuals have battled real fears of being attacked, abandoned, discriminated against and disadvantaged. </p> <p>In fact, LGBTQ+ youth are three times more likely to commit suicide than their heterosexual counterparts. Although it’s reasonable to show empathy for their parents, it’s poorly-timed here. Instead, try, “I hope you are coping well with your parents’ response. I am here to talk if you need to. Thanks for coming out me.”</p> <p><strong>"Why didn't you tell me before?"</strong></p> <p>Well, it’s likely because they were afraid. It’s not because you are a monster, but because they love you and feared losing you as a result of coming out. The important thing is to not take it personally. When a loved one comes out, you are being called on to show targeted and urgent empathy. While your pain of being “left out” is real, it can wait a day or two. </p> <p>Right now, your focus should be how to celebrate your loved one’s life and the choices they’ve made, including the one of having just come out to you. Kick off the celebration by saying, “I am so proud that you have chosen to live your truth in front of me. Thanks for being authentic with me.”</p> <p><strong>"Are you the man or the woman in the relationship?"</strong></p> <p>More than anything, this question demonstrates a fundamental ignorance of the concept of same-sex love. It also misplaces the focus on the sexual act (rather than on identity) at a time when they’re in a vulnerable state. When a person comes out, they’re opening their hearts to you and sharing the emotional reality of who they are as individuals. </p> <p>Instead of asking this question, reinforce how grateful you are that the person has had the courage to come out to you, and say, “I accept you for who you are. Thank you for coming out to me.”</p> <p><strong>"Would you be my gay bestie?"</strong></p> <p>People who identify as LGBTQ+ can be good (or insufferable) company just like any other human being, but the point is, they are human beings and not objects or accessories as the pop culture depiction of the “gay bestie” might have you believe. </p> <p>Instead of this response, take this opportunity to reaffirm your loving, supportive relationship: “You are brave and honest, and this makes me respect you even more. Thanks for coming out to me.”</p> <p><strong>"I knew it!"</strong></p> <p>This particularly hurtful response is generally remarked when a “feminine” man or “butch” woman comes out. Many gender non-conforming individuals try very hard to either tone-down or manage their sexuality in public for fear of homophobia. </p> <p>By saying “I knew it!,” you’re inadvertently suggesting that their sexuality or gender non-conformity was being gossiped about behind their back in a sneaky, judgmental manner, which could, in turn, lead the person to feel that staying in the closet was a safer option than coming out. To avoid this situation, stick with a response of, “I’m honoured you chose to come out to me. Thank you.”</p> <p><strong>"But you're so masculine!"</strong></p> <p>On the opposite end of the spectrum lies this response, indicating disbelief that a “manly” man could be gay, or that a “feminine” woman could be lesbian. Being in the closet is an alienating experience; responding to an individual’s coming-out with a comment that suggests they don’t conform to their “new” sexual identity either can be just as alienating. </p> <p>A better response could be, simply, “I didn’t know, but I’m so grateful you came out to me. Thank you.”</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.co.nz/true-stories-lifestyle/relationships/what-not-to-say-when-someone-comes-out-as-lgbtq-and-what-to-say-instead" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

What your hands say about your health

<p><em><a href="https://theconversation.com/profiles/adam-taylor-283950">Adam Taylor</a>, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a></em></p> <p>Your hands reveal a lot about the state of your health. This is something that has been recognised since at least the time of Hippocrates – the father of modern medicine.</p> <p>The ancient Greek physician <a href="https://jamanetwork.com/journals/jama/fullarticle/1150736">first described “clubbing”</a> in a patient with empyema (where pus fills the space between the lungs and the membrane around it) in the fifth century BC. Clubbing is where the nail looks like an upside-down spoon, and it is still recognised as a sign of disease. Although nowadays, clubbing is linked to more than just empyema. It is also <a href="https://my.clevelandclinic.org/health/symptoms/24474-nail-clubbing">linked to</a> cystic fibrosis, cirrhosis of the liver and thyroid conditions.</p> <p>Another nail change that can signal disease is Lindsay’s nails. This is where one or more nails are half white and half reddish brown. Around <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/ccr3.4426#ccr34426-bib-0007">50%</a> of people with <a href="https://www.nejm.org/doi/full/10.1056/nejmicm1406572">chronic kidney disease</a> have nails like this. But it can also be a sign of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8183706/">cirrhosis of the liver</a> and <a href="https://journal.chestnet.org/article/S0012-3692(15)41065-7/fulltext">Behcet’s disease</a>, a rare condition that causes inflammation of the blood vessels.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/13153107/">Terry’s nails</a>, where <a href="https://www.ccjm.org/content/ccjom/81/10/603.full.pdf">one or more fingernails</a> have a ground-glass appearance, can also be a sign of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6025669/">cirrhosis of the liver</a>, but they are also associated with type 2 diabetes, kidney failure and HIV.</p> <p>And sounding a bit more medical and a bit less like a high street nail bar is <a href="https://www.ncbi.nlm.nih.gov/books/NBK559136/">Muehrcke’s nails</a>, which is where one or more horizontal lines run across the fingernails. This nail pattern indicates a decrease in the most abundant protein in the blood: <a href="https://www.ncbi.nlm.nih.gov/books/NBK459198/">albumin</a>. These nail markings can be an indicator of <a href="https://www.amjmed.com/article/S0002-9343(10)00297-4/fulltext">kidney disease</a>.</p> <p>But sometimes changes in nail colour and pattern are not sinister and are merely signs of ageing. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3038811/">Neapolitan nails</a>, so called because of their three distinct colour zones, are often seen in people over the age of 70 and are nothing to worry about.</p> <h2>Palms</h2> <p>Nails aren’t the only part of the hand that can reveal ill health, though. The palms can tell a story too.</p> <p>If you find your palms are becoming sweaty in the absence of nervousness, hot temperatures or exercise, it could be down to faulty nerve signals causing the sweat glands to become active. This can be benign, in which case it is called primary hyperhidrosis. But unexplained sweaty palms – and face, neck and armpits – can be a sign of thyroid problems.</p> <p><a href="https://www.ncbi.nlm.nih.gov/books/NBK279480/">Hyperthyroidism</a> is where the thyroid gland in the neck produces too much <a href="https://www.ncbi.nlm.nih.gov/books/NBK500006/">thyroxine</a>. Excess of this hormone causes bodily processes to speed up and can be the cause of sweaty palms. Thankfully, this condition is easily treated with the right drugs.</p> <p>A more concerning palm change is the appearance of small areas of red or purple discolouration on the palms of the hands and fingers. This can be a sign of bacterial <a href="https://www.nhs.uk/conditions/endocarditis/">endocarditis</a> (inflammation of the inside lining of the heart), which has a high <a href="https://bmccardiovascdisord.biomedcentral.com/articles/10.1186/s12872-021-01853-6">mortality rate</a>.</p> <p>These discolourations come in two forms: <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3603816/">Osler’s nodes</a> and <a href="https://www.ahajournals.org/doi/10.1161/CIRCULATIONAHA.112.127787">Janeway lesions</a>. Osler’s nodes are typically painful <a href="https://link.springer.com/article/10.1007/s11739-014-1063-x">red 1mm-10mm</a> coloured nodules on the fingers appearing for hours to days, whereas Janeway lesions are <a href="https://heart.bmj.com/content/91/4/516">irregular shaped with varying sizes</a> and typically seen on the palms and are not painful, lasting few days up to a few weeks.</p> <p>Both these palm patterns are very serious and urgent medical attention should be sought.</p> <h2>Pins and needles</h2> <p>If you experience pins and needles in your hand that you can’t shake off, it might be a sign that you have <a href="https://www.nhs.uk/conditions/carpal-tunnel-syndrome/">carpal tunnel syndrome</a>. This is where a major nerve (the median nerve) in the wrist is being compressed, causing numbness, tingling or pain.</p> <p>It usually gets better without treatment, but a wrist splint can help to relieve pressure on the nerve. People who are overweight or pregnant are at greater risk of carpal tunnel syndrome.</p> <p>Pins and needles in the hand can also be a sign of diabetes. Raised blood sugar in diabetes causes <a href="https://www.webmd.com/diabetes/peripheral-neuropathy-risk-factors-symptoms">nerve damage</a> that manifests as <a href="https://www.nature.com/articles/s41572-019-0092-1">tingling or numbness</a> in the extremities, such as the hands.

Ballet flats are back. Here’s what the research says about how they affect your feet

<p><a href="https://theconversation.com/profiles/kristin-graham-1427672">Kristin Graham</a>, <em><a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em>; <a href="https://theconversation.com/profiles/helen-banwell-305575">Helen Banwell</a>, <em><a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em>, and <a href="https://theconversation.com/profiles/saravana-kumar-181105">Saravana Kumar</a>, <em><a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p>Ballet flat shoes – those thin-heeled lightweight slip-on shoes – are making a fashion <a href="https://www.vogue.com/slideshow/ballet-flats">comeback</a>. And it’s not hard to see why: they’re versatile, easy to wear, soft, flexible and often worn by celebrities.</p> <p>We have often been warned of the dangers of high-heeled shoes, so you might think ballet flats are problem-free.</p> <p>When you look at the research, however, a complicated picture emerges. There’s no definitive evidence to show ballet flats are generally harmful to foot health in the long-term. But ill-fitting ballet flats can be a problem.</p> <h2>Make sure it fits, especially in the toe box</h2> <p>An estimated <a href="https://pubmed.ncbi.nlm.nih.gov/30065787/">70%</a> of the population are wearing ill-fitting shoes. This mismatch between foot and shoe shape can increase foot pain, <a href="https://pubmed.ncbi.nlm.nih.gov/17507530/">reduce stability</a>, and can mean more blisters, corns and calluses. And habitual wearing of tight shoes has been <a href="https://www.sciencedirect.com/science/article/pii/S0958259207000533">associated</a> with bone changes in the toes and feet over time.</p> <p>Many flats feature a shallow and narrow toe box (the part of the shoe where the toes go). A too-small toe box often doesn’t align with the shape of a foot and ends up squishing the toes. It can also <a href="https://www.sciencedirect.com/science/article/pii/S0958259206000770">increase</a> pressure on top of and under the foot, and <a href="https://jfootankleres.biomedcentral.com/articles/10.1186/1757-1146-6-28">restrict</a> the movement of the forefoot during walking.</p> <p>But a too-big toe box is also a problem. Too much foot movement within the shoe can cause pressure and friction on the skin, which can also lead to calluses, corns, blisters, and wounds.</p> <p>A poorly fitting toe box can also cause micro trauma to toenails which, ultimately, can change <a href="https://www.researchgate.net/profile/Anuva-Bansal/publication/347522694_Traumatic_Nail_Disorders/links/60d6135592851ca94487df7e/Traumatic-Nail-Disorders.pdf">their look and thickness</a>.</p> <p>So if you’re wearing flats, make sure you choose a shoe with the right sized toe box.</p> <h2>What about the heel?</h2> <p>Health professionals often recommend a small heel over a completely flat shoe. Very flat shoes can <a href="https://pubmed.ncbi.nlm.nih.gov/27498844/">place</a> <a href="https://www.sciencedirect.com/science/article/pii/S0268003307002082">more</a> strain on the soft tissues that support the foot arch – specifically, the plantar fascia.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/27498844/">Research</a> has shown moving from a completely flat shoe to a small, raised heel reduces the tension force on the plantar fascia during standing activities.</p> <p>On the other hand, other <a href="https://journals.lww.com/jpojournal/Fulltext/2009/01000/Effects_of_Shoe_Heel_Height_on_the_Roll_Over.7.aspx#:%7E:text=The%20roll%2Dover%20shapes%20seem,without%20a%20change%20in%20alignment.&amp;text=Photographs%20of%20the%20prosthetic%20feet,shapes%20of%20these%20feet%20superimposed">research</a> has shown most people will adapt their ankle and knee motion to accommodate shoes of different heel heights.</p> <h2>What about support?</h2> <p>Ballet flats tend to have very flexible, thin soles and heel counters (the part, coloured red in this picture, that hugs the heel and the back part of the foot).</p> <p>These thin and flexible structures mean flats are often accused of lacking support. But debate rages among foot and shoe experts about how important support is in the first place.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/27729290/">Research</a> on barefoot-style shoes has shown walking in these types of shoes significantly reduces some loads on the knee compared to more stable supportive shoes.</p> <p>Minimalist shoes have also been found to <a href="https://pubmed.ncbi.nlm.nih.gov/30102872/">increase strength</a> in certain foot muscles used when we push off during walking, running or jumping.</p> <p>However, other research found stable supportive shoes can <a href="https://pubmed.ncbi.nlm.nih.gov/33428439/">improve knee pain</a> when walking more than flat flexible shoes.</p> <p>The thin soles in flats mean there is little cushioning under the foot. While more cushioning can improve comfort, and reduce stress and strain on your foot sole <a href="https://www.sciencedirect.com/science/article/abs/pii/S0021929011001758?casa_token=gecXFCMi0LcAAAAA:TazyTd8TRaAl_bG0jprifYIUIlWRDwEH6bVeymBYTWups2iDGMuUjLs2gaNqsiNGHVJhHC3J9AdB">skin</a>, there is no evidence it reduces loads across the lower leg.</p> <p>In fact, walking in cushioned shoes has been shown to <a href="https://pubmed.ncbi.nlm.nih.gov/20191571/">increase</a> the load on the knee compared to flat, flexible shoes.</p> <h2>So, what’s the verdict?</h2> <p>The verdict is mixed. Yes, there’s evidence poorly fitting shoes and a flat heel can be detrimental, with consequences seen in the <a href="https://www.sciencedirect.com/science/article/pii/S0966636221000199">rearfoot</a> (around the ankle) and <a href="https://www.sciencedirect.com/science/article/pii/S0966636218300687">knee</a>.</p> <p>But there’s also no hard evidence ballet flats cause long-term foot health problems.</p> <p>What matters is choosing a well-fitted shoe to suit your foot shape and needs.</p> <p>If you’re shopping for ballet flats, try to:</p> <ul> <li> <p>choose a pair with a toe box that does not cramp your toes and has a sole at least as wide as your foot</p> </li> <li> <p>choose flats that offer at least some structure and support</p> </li> <li> <p>choose a pair with a small heel rather being than completely flat.<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/207806/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> </li> </ul> <p><em><a href="https://theconversation.com/profiles/kristin-graham-1427672">Kristin Graham</a>, Lecturer in Podiatry, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a>; <a href="https://theconversation.com/profiles/helen-banwell-305575">Helen Banwell</a>, Lecturer in Podiatry, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a>, and <a href="https://theconversation.com/profiles/saravana-kumar-181105">Saravana Kumar</a>, Professor in Allied Health and Health Services Research, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Does it matter what time of day I eat? And can intermittent fasting improve my health? Here’s what the science says

<p><em><a href="https://theconversation.com/profiles/frederic-gachon-1379094">Frederic Gachon</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> and <a href="https://theconversation.com/profiles/meltem-weger-1408599">Meltem Weger</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a></em></p> <p>Early hunter-gatherers faced long periods of fasting. Their <a href="https://pubmed.ncbi.nlm.nih.gov/35834774/">access to food</a> relied on successful hunting, fishing, and the availability of wild plants.</p> <p>Over time, the development of modern agriculture and the transition to industrialised societies <a href="https://pubmed.ncbi.nlm.nih.gov/35834774/">changed our regular eating patterns</a>, shifting our dinner time to later in the day to accommodate work schedules.</p> <p>Today, with access to an abundance of food, we rarely experience prolonged periods of fasting, except for weight loss or religious practices. It’s <a href="https://pubmed.ncbi.nlm.nih.gov/26411343/">now common</a> to have four or more meals a day, with the most calories consumed later in the day. Frequent snacking is also common, over a window of around 15 hours.</p> <p>However, research increasingly shows our health is not only affected by what and how much we eat, but also <em>when</em> we eat. So what does this mean for meal scheduling? And can intermittent fasting help?</p> <h2>Our body clock controls more than our sleep</h2> <p>Our internal biological timekeeper, or circadian clock, regulates many aspects of our physiology and behaviour. It tells us to be awake and active during the day, and <a href="https://theconversation.com/does-it-matter-what-time-i-go-to-bed-198146">rest and sleep</a> during the night. It can also tell us the best time to eat.</p> <p>Our body is biologically prepared to have food during the day. Food digestion, nutrient uptake and energy metabolism is optimised to occur when we’re supposed to be active and eating.</p> <p>Working against this default stage, by regularly eating when we’re supposed to sleep and fast, can compromise these processes and impact our health. <a href="https://pubmed.ncbi.nlm.nih.gov/31813351/">Erratic eating patterns</a>, including late-night meals, have been linked to <a href="https://pubmed.ncbi.nlm.nih.gov/36198293/">weight gain</a> and a greater risk of metabolic disease.</p> <p>Shift-workers, for example, and people who work evening, night or rotating shifts, have a <a href="https://theconversation.com/why-does-night-shift-increase-the-risk-of-cancer-diabetes-and-heart-disease-heres-what-we-know-so-far-190652">higher risk</a> of obesity, heart disease and diabetes.</p> <p>But adopting an eating pattern that aligns with our circadian rhythm can reduce these risks.</p> <h2>So can intermittent fasting help?</h2> <p>Nutritional interventions are increasingly focused not only on “what” we eat but also “when”. Intermittent fasting is one way to restrict the timing, rather than the content, of what we eat.</p> <p>There are <a href="https://pubmed.ncbi.nlm.nih.gov/35834774/">several types</a> of intermittent fasting, one of which is time-restricted eating. This means eating all our calories in a consistent 8-12 hour, or even shorter, interval each day.</p> <p>But is it backed by evidence?</p> <p>Most of what we know today about intermittent fasting and time-restricted eating is from <a href="https://pubmed.ncbi.nlm.nih.gov/35834774/">mouse studies</a>, which demonstrate remarkable weight loss and overall health benefits associated with these types of dietary interventions.</p> <p>However, some aspects of mouse physiology can be different to humans. Mice need to eat more frequently than humans and even a short period of fasting has a more significant physiological impact on mice. One day of fasting in mice leads to a 10% <a href="https://www.sciencedirect.com/science/article/pii/S2212877820301320">loss of body weight</a>, whereas humans would need to fast for 14 days to achieve <a href="https://pubmed.ncbi.nlm.nih.gov/30881957/">similar results</a>. This makes a direct translation from mice to humans more complicated.</p> <p>While health benefits of <a href="https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2623528">intermittent fasting</a> and <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa2114833">time-restricted eating</a> have also been observed in humans, the findings in respect of weight loss are less clear. Current data suggest only modest, if any, weight loss in human participants who undergo these diet regimens when compared to calorie-restricted diets.</p> <p>Drawing <a href="https://pubmed.ncbi.nlm.nih.gov/35834774/">definitive conclusions</a> in humans may be more <a href="https://pubmed.ncbi.nlm.nih.gov/32480126/">difficult</a> because of the small sample sizes and individual differences in metabolism, variations in study design (such as the use of different protocols with varying times and duration of food restriction), and participants not complying with their instructions.</p> <h2>Health benefits could be due to eating fewer calories</h2> <p>Most studies describing the health benefits of <a href="https://pubmed.ncbi.nlm.nih.gov/33466692/#:%7E:text=and%20Future%20Perspectives-,Time%2DRestricted%20Eating%20and%20Metabolic%20Syndrome%3A%20Current%20Status%20and%20Future,doi%3A%2010.3390%2Fnu13010221.">time restricted eating</a> or <a href="https://pubmed.ncbi.nlm.nih.gov/27569118/">intermittent fasting</a> also found these diets were accompanied by calorie restriction: reducing the time of food access implicitly leads people to eat less.</p> <p>Studies that controlled calorie intake did not detect any more benefits of intermittent fasting than <a href="https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2623528">calorie restriction</a> alone.</p> <p>The weight loss and health benefits observed with intermittent fasting is likely attributed due to the resultant reduction in <a href="https://pubmed.ncbi.nlm.nih.gov/34135111/">calorie intake</a>. <a href="https://pubmed.ncbi.nlm.nih.gov/32986097/">Similar findings</a> have been reported for time-restricted eating.</p> <h2>Benefit of following our body clock</h2> <p>Nevertheless, time-restricted eating offers additional health benefits in humans, such as improved glucose metabolism and blood pressure, even without differences in calorie intake, in particular when restricted to the <a href="https://pubmed.ncbi.nlm.nih.gov/29754952/">earlier part of the day</a> (that is, when having a six-hour eating window with dinner before 3pm).</p> <p>Restricting food intake to the daytime for shift-workers <a href="https://pubmed.ncbi.nlm.nih.gov/28635334/">can alleviate</a> metabolic differences caused by shift-work, whereas this effect is not observed when food intake is restricted to <a href="https://www.science.org/doi/10.1126/sciadv.abg9910">nighttime</a>.</p> <p>One idea is that consuming food early, in alignment with our circadian rhythm, helps to <a href="https://pubmed.ncbi.nlm.nih.gov/28578930/">synchronise our circadian clock</a>. This restores the rhythm of our autonomous nervous system, which regulates essential functions such as breathing and heart rate, to keep our physiology “tuned”, as it was shown <a href="https://www.pnas.org/doi/10.1073/pnas.2015873118">in mice</a>.</p> <p>While there’s much still to learn from research in this field, the evidence suggests that to maintain a healthy weight and overall wellbeing, aim for regular, nutritious meals during the day, while avoiding late-night eating and frequent snacking.<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/203762/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/frederic-gachon-1379094">Frederic Gachon</a>, Associate Professor, Physiology of Circadian Rhythms, Institute for Molecular Bioscience, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> and <a href="https://theconversation.com/profiles/meltem-weger-1408599">Meltem Weger</a>, Postdoctoral Research Fellow, Institute for Molecular Bioscience, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Does a woman’s menstrual cycle affect her athletic performance? Here’s what the science says

<p><em><a href="https://theconversation.com/profiles/sara-chica-latorre-1443479">Sara Chica-Latorre</a>, <a href="https://theconversation.com/institutions/university-of-canberra-865">University of Canberra</a> and <a href="https://theconversation.com/profiles/michael-pengelly-1443674">Michael Pengelly</a>, <a href="https://theconversation.com/institutions/university-of-canberra-865">University of Canberra</a></em></p> <p>During the Women’s FIFA World Cup, it has been wonderful to see the spotlight turn to female athletes.</p> <p>There’s always been <a href="https://pubmed.ncbi.nlm.nih.gov/24766579/">more research on male athletes</a> compared to female athletes, but the gap is narrowing.</p> <p>One thing we still don’t know enough about is the effect of the menstrual cycle on athletic performance.</p> <h2>What does the menstrual cycle do to a woman’s body?</h2> <p>The menstrual cycle is a complex cascade of events typically lasting 28 days. The primary female sex hormones oestrogen and progesterone rise and fall as the body cycles through four phases, beginning at menstruation, maturation and releasing of an egg (ovulation), preparation for pregnancy, and restarting the cycle if the egg is not fertilised.</p> <p>Fluctuations in female sex hormones have been associated with changes in inflammation, metabolism, muscle activation and body composition, which <a href="https://pubmed.ncbi.nlm.nih.gov/33572406/">can influence athletic performance</a>.</p> <p>For instance, <a href="https://pubmed.ncbi.nlm.nih.gov/22306563/">inflammation decreases</a> when the body is preparing to ovulate, reaching its lowest point around ovulation. It then increases following ovulation and peaks during menstruation.</p> <p>This peak coincides with lower perceived performance among many female athletes.</p> <p>The menstrual cycle can also give rise to symptoms including pain, cramps, weakness, and poor sleep and focus, <a href="https://pubmed.ncbi.nlm.nih.gov/35911030/">challenging performance</a> during training and competition.</p> <p>For example, <a href="https://doi.org/10.1080/24733938.2021.2020330">research</a> conducted in elite female soccer players found over 87% of players perceived reduced power and increased fatigue during menstruation, while over 66% perceived their reaction time and recovery to be affected.</p> <p>Considering the approximate maximum career length of soccer players (21 years) and a woman’s fertile life, that adds up to about 250 times throughout a woman’s soccer career that performance may be compromised.</p> <p>Trends observed among female soccer players closely mirror the experiences of other female athletes, with over <a href="https://pubmed.ncbi.nlm.nih.gov/37389782/#:%7E:text=Results%3A%20Sixty%20studies%20involving%206380,the%20most%20prevalent%20MC%20disorder">74% reporting</a> negative effects mainly during the first days of menstruation.</p> <p>For some, this may lead to reduced training participation, potentially compromising skill development, fitness levels, and even their chances of being selected for competition.</p> <p>But the menstrual cycle is complex, and its effects can vary between athletes and sports. Consequently there is disagreement regarding whether the menstrual cycle universally affects athletic performance, with <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10076834/#:%7E:text=Findings%20suggest%20that%20strength%2Drelated,cause%20variations%20in%20strength%20performance">some research</a> <a href="https://pubmed.ncbi.nlm.nih.gov/32661839/">indicating</a> no influence of the menstrual cycle on certain performance measures. But these studies are few and had various logistical limitations, including a small number of participants.</p> <p>Also important to note is that most studies to-date have excluded women using hormonal contraceptives, which is about <a href="https://pubmed.ncbi.nlm.nih.gov/29283683/">50% of female athletes</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/35475746/#:%7E:text=Conclusion%3A%20Most%20WSL%20players%20do,minimise%20discomfort%20and%20maximise%20performance.">28% of female soccer players</a>. The use of hormonal contraceptives suppresses natural hormonal fluctuations and replaces them with external synthetic versions of female sex hormones, affecting the athlete differently.</p> <p>Clearly the extent and severity to which the menstrual cycle impacts athletic performance is highly variable and complex, with more research needed. So for now it’s sensible to consider the effects of the menstrual cycle on an individual basis.</p> <h2>How to support athletic performance at all cycle stages</h2> <p>It’s essential for players to familiarise themselves with their own cycles to understand how they’re affected throughout, as well as communicate any menstrual cycle-related issues to support staff (physicians and coaches). This awareness can guide adjustments in training and nutrition when required.</p> <p>For example, oestrogen has an important influence on iron levels in females, such as chronic oestrogen deficiency is <a href="https://pubmed.ncbi.nlm.nih.gov/23041085/">linked to iron deficiency</a>. Iron status can also be compromised by blood loss during menstruation, depending on the heaviness and duration of bleeding.</p> <p>Iron is essential for human function, facilitating energy production and the transportation of oxygen around the body. In soccer, about <a href="https://pubmed.ncbi.nlm.nih.gov/16521852/#:%7E:text=Of%20the%20investigated%20female%20soccer,at%20the%20top%20international%20level">60% of elite female players</a> present as iron deficient, compared to <a href="https://pubmed.ncbi.nlm.nih.gov/18384395/">less than 12% of their male counterparts</a>. For an iron deficient midfielder, this might translate into covering less distance at lower speeds.</p> <p>It’s therefore important female athletes have their iron levels regularly checked by qualified practitioners. Addressing deficiencies through diet, supplementation, or iron transfusions, will ensure athletic performance during training and competition is not compromised.</p> <p>Individual athletes’ training loads can also be strategically managed to accommodate severe menstrual symptoms.</p> <p>Football clubs around the world have been <a href="https://www.tandfonline.com/doi/full/10.1080/24733938.2020.1828615">experimenting with this strategy</a> since it gained popularity during the 2019 Women’s FIFA World Cup. But how does it look in practice?</p> <p>For team sport athletes, such as soccer players, this can be a demanding logistical task. It’s not easy to track the menstrual cycles of more than 25 players concurrently, and hold training sessions at convenient times for all of them. The complexities are heightened when training and game days cannot be avoided.</p> <p>But performance coaches must consider athletes’ needs and ensure they’re prepared for competition, while minimising the risk of injury and menstrual discomfort. Coaches should also ensure athletes maintain adequate nutrition for both competition and to support their menstrual cycle.</p> <p>For an athlete who reports severe menstrual symptoms during the first days of menstruation (such as increased pain and weakness), this might translate into reduced training intensity, additional recovery days, and an anti-inflammatory diet that also supports the restoration of iron levels (increased intake of nuts, seeds, berries, lean red meats, and fibre and Omega-3 rich foods).</p> <p>And it’s important to keep in mind some athletes might experience menstrual cycle issues in phases other than menstruation. So, training and nutrition should be flexible and individualised across the cycle.</p> <p>Using this approach, athletes can mitigate the influence of the menstrual cycle on their performance, giving them the best opportunity to achieve their athletic potential and success during competition.<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/206700/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/sara-chica-latorre-1443479">Sara Chica-Latorre</a>, Phd Candidate and Research Assistant, Research Institute for Sport and Exercise, <a href="https://theconversation.com/institutions/university-of-canberra-865">University of Canberra</a> and <a href="https://theconversation.com/profiles/michael-pengelly-1443674">Michael Pengelly</a>, PhD Candidate, Research Institute for Sport and Exercise, <a href="https://theconversation.com/institutions/university-of-canberra-865">University of Canberra</a></em></p> <p><em>Image credits: Getty Images </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Do psychedelics really work to treat depression and PTSD? Here’s what the evidence says

<p><em><a href="https://theconversation.com/profiles/sam-moreton-194043">Sam Moreton</a>, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a></em></p> <p>As of July 1, authorised psychiatrists have been allowed to prescribe MDMA (the chemical found in “ecstasy”) to treat post-traumatic stress disorder (PTSD), and psilocybin (found in “magic mushrooms”) to treat depression that hasn’t responded to other treatment.</p> <p>Psychedelic therapies have researchers excited because evidence suggests they might have lasting beneficial effects on factors that cause psychological distress beyond the treatment period. These include <a href="https://link.springer.com/article/10.1007/s00213-017-4701-y">feeling disconnected from other people</a>, <a href="https://link.springer.com/article/10.1007/s00213-019-05391-0">fear of death</a>, and <a href="https://www.sciencedirect.com/science/article/pii/S2212144719301140?casa_token=OP6tKGxjPHAAAAAA:NTQ4khgsOY5wmsQ5HzCMcZ4eZ43wQV-sdhUbf5LXFiIeKWNwdonhfCxo77k7QbNk4G69EfX-">rigid ways of thinking</a>.</p> <p>This stands in contrast to most medications for psychological issues, which only directly help while people keep taking them regularly.</p> <p>But how strong is the evidence for psychedelic therapy?</p> <h2>Early promise</h2> <p>Early results from studies around the world have found psychedelic therapy <a href="https://www.ranzcp.org/getmedia/0cf57ea2-0bd7-4883-9155-d2ba1958df86/cm-therapeutic-use-of-mdma-for-ptsd-and-psilocybin-for-treatment-resistant-depression.pdf">might be effective</a> for treating a range of psychological issues.</p> <p>For instance, most studies (<a href="https://www.nejm.org/doi/full/10.1056/NEJMoa2032994">but not all</a>) have found patients tend to report <a href="https://pubmed.ncbi.nlm.nih.gov/37357767/">fewer depression symptoms</a> for periods ranging from several weeks to several months after psilocybin therapy.</p> <p>Similarly, studies have found <a href="https://journals.sagepub.com/doi/10.1177/0269881120965915">reductions in PTSD symptoms</a> three weeks after MDMA therapy.</p> <h2>Not so fast</h2> <p>However, as psychedelic research has grown, <a href="https://pubmed.ncbi.nlm.nih.gov/35243919/">limitations</a> of the research have been identified by researchers both <a href="https://psyarxiv.com/ak6gx/">within</a> and <a href="https://www.sciencefictions.org/p/psychedelics">outside</a> the psychedelic field.</p> <p>One issue is that we aren’t sure whether findings might be due to a <a href="https://www.betterhealth.vic.gov.au/health/conditionsandtreatments/placebo-effect">placebo effect</a>, which occurs when a treatment works because people expect it to work.</p> <p>In clinical trials, participants are often given either a medication or a placebo (inactive) drug – and it’s important they don’t know which they have been given. However, due to the strong effects, it is difficult to prevent participants from knowing whether they have been given a psychedelic drug.</p> <p>Researchers have tried to use a range of different drugs (such as Ritalin) as a placebo in order to “trick” those participants not given a psychedelic into thinking they have received one. But this can be difficult to achieve.</p> <p>In 2021, researchers <a href="https://www.tandfonline.com/doi/full/10.1080/17512433.2021.1933434?casa_token=Dovn7x_rkdUAAAAA%3AsPzBTYNTPnNwqj9NvwN0m9ptrP4x4-c83gp3tGcshs30dWHNnmB_Vx-X5H5Y3pZJdG02IWW6X2E">reviewed</a> clinical trials involving psychedelics such as LSD, psilocybin, and dimethyltryptamine (found in animals and plants) for mood and anxiety disorders. They found trials either had not assessed whether participants guessed correctly which drug they had been given, or that this had been tested and participants tended to guess correctly.</p> <p>More recent trials <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa2032994">either don’t measure this</a> or find participants have a <a href="https://journals.sagepub.com/doi/full/10.1177/02698811231154852?casa_token=VsPt344fVGwAAAAA%3AA-i1VPBE1EWyFITWNncZEt876lWMiC7rtTOLJBQnb2pHI2775imUJhrzeSZW6r9doaBeDaj61D0">pretty good idea</a> of whether they’ve had a placebo or a psychedelic drug.</p> <p>Given the publicity and excitement around psychedelic research in recent years, it is likely most participants have <a href="https://culanth.org/fieldsights/the-pollan-effect-psychedelic-research-between-world-and-word">strong beliefs</a> such therapies work. This could lead to a significant placebo effect for participants given a psychedelic dose. Additionally, participants who realise they have received a placebo could experience <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10184717/">disappointment and frustration</a>, resulting in worse symptoms. The benefits of a psychedelic may seem even greater when they are compared to the experiences of disappointed participants.</p> <h2>Translating trials to practice</h2> <p>Anecdotally, patients might be motivated to report they have gotten better, even when they haven’t.</p> <p>On a 2021 podcast, one clinical trial participant <a href="https://www.psymposia.com/powertrip/">described</a> how, in hindsight, the information they provided to the trial did not accurately capture the worsening of their symptoms. Trial participants are likely aware their results might affect whether treatments are legalised. They may not want to “ruin” the research by admitting the treatment didn’t work for them.</p> <p>There is also uncertainty about whether the findings from clinical trials mean treatments will work in private practice. There may be a lack of clarity around <a href="https://psyarxiv.com/ak6gx/">how trial participants</a> are recruited and selected. Therefore participants may not represent the typical person with PTSD or treatment-resistant depression.</p> <p>And while <a href="https://journals.sagepub.com/doi/full/10.1177/02698811211069100">the safety of psychedelics</a> within controlled contexts is often emphasised by advocates, less is known about safety of psychedelic therapy <a href="https://www.frontiersin.org/articles/10.3389/fpsyt.2021.737738/full">outside</a> clinical trials.</p> <h2>Resolving issues</h2> <p>These issues do not mean the promising psychedelic research conducted over the past several decades is worthless. Nevertheless, a <a href="https://pubmed.ncbi.nlm.nih.gov/35285280/#full-view-affiliation-1">recent review</a> of the effects of MDMA and psilocybin on mental, behavioural or developmental disorders by Australian researchers concluded the “overall certainty of evidence was low or very low”.</p> <p>Dutch researchers recently drafted a <a href="https://psyarxiv.com/ak6gx/">roadmap for psychedelic science</a> with a checklist for future research to help avoid these pitfalls. When more research is done, it might turn out psychedelic treatments help patients and don’t come with unacceptable harms – we simply don’t know that yet.<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/208857/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/sam-moreton-194043">Sa<em>m Moreton</em></a><em>, Associate Lecturer, School of Psychology, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

What your hugs say about your relationships

<p>When you go in for a hug with a loved one (or a not-so-loved one), chances are you aren’t thinking too much about it. It’s a sort of natural, automatic response, right? Well, it turns out your hugs actually say a lot about your relationship with the person you’re embracing.</p> <p><a href="https://link.springer.com/article/10.1007/s00426-018-0985-8" target="_blank" rel="noopener">A study</a><strong> </strong>has found that the side we lean to when hugging someone speaks volumes about how we feel towards them.</p> <p>German researchers analysed more than 2,000 hugs in departures and arrivals at an airport and compared them to 500 embraces between strangers.</p> <p>What they found was that during more intense, emotional hugs we lean to the left with our left arm reaching out first to our partner’s right arm, while in less emotionally-charged embraces we turn to the right, extending our right arm to our partner’s left arm.</p> <p>“This is because of the influence of the right hemisphere, which controls the left side of the body and processes both positive and negative emotions,” lead author, Julian Packheiser of Germany’s Ruhr University Bochum, said.</p> <p>“When people hug, emotional and motor networks in the brain interact and cause a stronger drift to the left in emotional contexts.”</p> <p>However, the rules change when it comes to two men embracing. In this case, researchers noticed a strong inclination towards the typically more emotionally-charged left-side hugs even when in neutral situations.</p> <p>“Our interpretation is that many men consider embraces between men to be something negative; therefore, they tend to perceive hugs as negative even in a neutral situation, such as saying hello,” the study’s co-author Sebastian Ocklenburg explained.</p> <p>However, some are sceptical as to the accuracy of the study, which assumed that people hugging in airport departures were feeling negative emotions while those hugging in arrivals were experiencing positive emotions.</p> <p>“I personally don’t buy that,” body language and communication expert Dr Lillian Glass told <em><a href="http://www.newsweek.com/show-me-how-you-really-feel-hugging-left-right-reveals-your-true-emotions-says-791417" target="_blank" rel="noopener"><strong><span style="text-decoration: underline;">Newsweek</span></strong></a>.</em> “When you hug someone there’s a great deal of various emotions that are involved. Also, most people are statistically right-handed, so you’re going to go to the right side.”</p> <p>So, the next time you give someone a hug, try and notice which side you’re leaning towards and see if these findings apply to your relationships.</p> <p><em>Image credit: Shutterstock</em></p>
