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

<a href="https://theconversation.com/profiles/giuliana-murfet-1517219">Giuliana Murfet</a>, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a> and <a href="https://theconversation.com/profiles/shanshan-lin-1005236">ShanShan Lin</a>, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a> Not getting enough sleep is a common affliction in the modern age. If you don’t always get as many hours of shut-eye as you’d like, perhaps you were concerned by news of a <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2815684">recent study</a> that found people who sleep less than six hours a night are at higher risk of type 2 diabetes. So what can we make of these findings? It turns out the relationship between sleep and diabetes is complex. <h2>The study</h2> Researchers analysed data from the <a href="https://www.ukbiobank.ac.uk/">UK Biobank</a>, a large biomedical database which serves as a global resource for health and medical research. They looked at information from 247,867 adults, following their health outcomes for more than a decade. The researchers wanted to understand the associations between sleep duration and type 2 diabetes, and whether a healthy diet reduced the effects of short sleep on diabetes risk. As part of their involvement in the UK Biobank, participants had been asked roughly how much sleep they get in 24 hours. Seven to eight hours was the average and considered normal sleep. Short sleep duration was broken up into three categories: mild (six hours), moderate (five hours) and extreme (three to four hours). The researchers analysed sleep data alongside information about people’s diets. Some 3.2% of participants were diagnosed with type 2 diabetes during the follow-up period. Although healthy eating habits were associated with a lower overall risk of diabetes, when people ate healthily but slept less than six hours a day, their risk of type 2 diabetes increased compared to people in the normal sleep category. The researchers found sleep duration of five hours was linked with a 16% higher risk of developing type 2 diabetes, while the risk for people who slept three to four hours was 41% higher, compared to people who slept seven to eight hours. One limitation is the study defined a healthy diet based on the number of servings of fruit, vegetables, red meat and fish a person consumed over a day or a week. In doing so, it didn’t consider how dietary patterns such as time-restricted eating or the Mediterranean diet may modify the risk of diabetes among those who slept less. Also, information on participants’ sleep quantity and diet was only captured at recruitment and may have changed over the course of the study. The authors acknowledge these limitations. <h2>Why might short sleep increase diabetes risk?</h2> In people with <a href="https://www.diabetesaustralia.com.au/about-diabetes/type-2-diabetes/">type 2 diabetes</a>, the body becomes resistant to the effects of a hormone called insulin, and slowly loses the capacity to produce enough of it in the pancreas. Insulin is important because it regulates glucose (sugar) in our blood that comes from the food we eat by helping move it to cells throughout the body. We don’t know the precise reasons why people who sleep less may be at higher risk of type 2 diabetes. But <a href="https://doi.org/10.7759/cureus.23501">previous research</a> has shown sleep-deprived people often have increased <a href="https://doi.org/10.1186/1476-511X-9-125">inflammatory markers</a> and <a href="https://doi.org/10.1007/s00125-015-3500-4">free fatty acids</a> in their blood, which <a href="https://doi.org/10.1007/s11892-018-1055-8">impair insulin sensitivity</a>, leading to <a href="https://doi.org/10.7759/cureus.23501">insulin resistance</a>. This means the body struggles to use insulin properly to regulate blood glucose levels, and therefore increases the risk of type 2 diabetes. Further, people who don’t sleep enough, as well as people who sleep in irregular patterns (such as shift workers), experience disruptions to their body’s natural rhythm, known as the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5995632/">circadian rhythm</a>. This can interfere with the release of hormones like <a href="https://doi.org/10.1210/edrv.18.5.0317">cortisol, glucagon and growth hormones</a>. These hormones are released through the day to meet the body’s changing energy needs, and normally keep blood glucose levels nicely balanced. If they’re compromised, this may reduce the body’s ability to handle glucose as the day progresses. These factors, and <a href="https://www.science.org/doi/10.1126/sciadv.aar8590">others</a>, may contribute to the increased risk of type 2 diabetes seen among people sleeping less than six hours. While this study primarily focused on people who sleep eight hours or less, it’s possible longer sleepers may also face an increased risk of type 2 diabetes. Research has previously shown a U-shaped correlation between sleep duration and type 2 diabetes risk. A <a href="https://doi.org/10.2337/dc14-2073">review</a> of multiple studies found getting between seven to eight hours of sleep daily was associated with the lowest risk. When people got less than seven hours sleep, or more than eight hours, the risk began to increase. The reason sleeping longer is associated with increased risk of type 2 diabetes may be linked to <a href="https://doi.org/10.2337/dc15-0186">weight gain</a>, which is also correlated with longer sleep. Likewise, people who don’t sleep enough are more likely to be <a href="https://doi.org/10.1016/j.sleh.2017.07.013">overweight or obese</a>. <h2>Good sleep, healthy diet</h2> Getting enough sleep is an important part of a healthy lifestyle and may reduce the risk of type 2 diabetes. Based on this study and other evidence, it seems that when it comes to diabetes risk, seven to eight hours of sleep may be the sweet spot. However, other factors could influence the relationship between sleep duration and diabetes risk, such as individual differences in sleep quality and lifestyle. While this study’s findings question whether a healthy diet can mitigate the effects of a lack of sleep on diabetes risk, a wide range of evidence points to the benefits of <a href="https://www.who.int/initiatives/behealthy/healthy-diet">healthy eating</a> for overall health. The <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2815684">authors of the study</a> acknowledge it’s not always possible to get enough sleep, and suggest doing <a href="https://pubmed.ncbi.nlm.nih.gov/33137489/">high-intensity interval exercise</a> during the day may offset some of the potential effects of short sleep on diabetes risk. In fact, exercise <a href="https://doi.org/10.1016/j.jshs.2023.03.001">at any intensity</a> can improve blood glucose levels.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/225179/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/giuliana-murfet-1517219">Giuliana Murfet</a>, Casual Academic, Faculty of Health, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a> and <a href="https://theconversation.com/profiles/shanshan-lin-1005236">ShanShan Lin</a>, Senior Lecturer, School of Public Health, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How long does back pain last? And how can learning about pain increase the chance of recovery?

<a href="https://theconversation.com/profiles/sarah-wallwork-1361569">Sarah Wallwork</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> and <a href="https://theconversation.com/profiles/lorimer-moseley-1552">Lorimer Moseley</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> Back pain is common. One in thirteen people have it right now and worldwide a staggering 619 million people will <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7186678/">have it this year</a>. Chronic pain, of which back pain is the most common, is the world’s <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7186678/">most disabling</a> health problem. Its economic impact <a href="https://www.ncbi.nlm.nih.gov/books/NBK92510/">dwarfs other health conditions</a>. If you get back pain, how long will it take to go away? We scoured the scientific literature to <a href="https://www.cmaj.ca/content/cmaj/196/2/E29.full.pdf">find out</a>. We found data on almost 20,000 people, from 95 different studies and split them into three groups: <ul> <li>acute – those with back pain that started less than six weeks ago</li> <li>subacute – where it started between six and 12 weeks ago</li> <li>chronic – where it started between three months and one year ago.</li> </ul> We found 70%–95% of people with acute back pain were likely to recover within six months. This dropped to 40%–70% for subacute back pain and to 12%–16% for chronic back pain. Clinical guidelines point to graded return to activity and pain education under the guidance of a health professional as the best ways to promote recovery. Yet these effective interventions are underfunded and hard to access. <h2>More pain doesn’t mean a more serious injury</h2> Most acute back pain episodes are <a href="https://www.racgp.org.au/getattachment/75af0cfd-6182-4328-ad23-04ad8618920f/attachment.aspx">not caused</a> by serious injury or disease. There are rare exceptions, which is why it’s wise to see your doctor or physio, who can check for signs and symptoms that warrant further investigation. But unless you have been in a significant accident or sustained a large blow, you are unlikely to have caused much damage to your spine. Even very minor back injuries can be brutally painful. This is, in part, because of how we are made. If you think of your spinal cord as a very precious asset (which it is), worthy of great protection (which it is), a bit like the crown jewels, then what would be the best way to keep it safe? Lots of protection and a highly sensitive alarm system. The spinal cord is protected by strong bones, thick ligaments, powerful muscles and a highly effective alarm system (your nervous system). This alarm system can trigger pain that is so unpleasant that you cannot possibly think of, let alone do, anything other than seek care or avoid movement. The messy truth is that when pain persists, the pain system becomes more sensitive, so a widening array of things contribute to pain. This pain system hypersensitivity is a result of neuroplasticity – your nervous system is becoming better at making pain. <h2>Reduce your chance of lasting pain</h2> Whether or not your pain resolves is not determined by the extent of injury to your back. We don’t know all the factors involved, but we do know there are things that you can do to reduce chronic back pain: <ul> <li> understand how pain really works. This will involve intentionally learning about modern pain science and care. It will be difficult but rewarding. It will help you work out what you can do to change your pain </li> <li> reduce your pain system sensitivity. With guidance, patience and persistence, you can learn how to gradually retrain your pain system back towards normal. </li> </ul> <h2>How to reduce your pain sensitivity and learn about pain</h2> Learning about “how pain works” provides the most sustainable <a href="https://www.bmj.com/content/376/bmj-2021-067718">improvements in chronic back pain</a>. Programs that combine pain education with graded brain and body exercises (gradual increases in movement) can reduce pain system sensitivity and help you return to the life you want. These programs have been in development for years, but high-quality clinical trials <a href="https://jamanetwork.com/journals/jama/fullarticle/2794765">are now emerging</a> and it’s good news: they show most people with chronic back pain improve and many completely recover. But most clinicians aren’t equipped to deliver these effective programs – <a href="https://www.jpain.org/article/S1526-5900(23)00618-1/fulltext">good pain education</a> is not taught in most medical and health training degrees. Many patients still receive ineffective and often risky and expensive treatments, or keep seeking temporary pain relief, hoping for a cure. When health professionals don’t have adequate pain education training, they can deliver bad pain education, which leaves patients feeling like they’ve just <a href="https://www.jpain.org/article/S1526-5900(23)00618-1/fulltext">been told it’s all in their head</a>. Community-driven not-for-profit organisations such as <a href="https://www.painrevolution.org/">Pain Revolution</a> are training health professionals to be good pain educators and raising awareness among the general public about the modern science of pain and the best treatments. Pain Revolution has partnered with dozens of health services and community agencies to train more than <a href="https://www.painrevolution.org/find-a-lpe">80 local pain educators</a> and supported them to bring greater understanding and improved care to their colleagues and community. But a broader system-wide approach, with government, industry and philanthropic support, is needed to expand these programs and fund good pain education. To solve the massive problem of chronic back pain, effective interventions need to be part of standard care, not as a last resort after years of increasing pain, suffering and disability.<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/222513/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/sarah-wallwork-1361569">Sarah Wallwork</a>, Post-doctoral Researcher, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> and <a href="https://theconversation.com/profiles/lorimer-moseley-1552">Lorimer Moseley</a>, Professor of Clinical Neurosciences and Foundation Chair in Physiotherapy, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Do stress and depression increase the risk of Alzheimer’s disease? Here’s why there might be a link

<a href="https://theconversation.com/profiles/yen-ying-lim-355185">Yen Ying Lim</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> and <a href="https://theconversation.com/profiles/ivana-chan-1477100">Ivana Chan</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> Dementia affects more than <a href="https://www.who.int/news-room/fact-sheets/detail/dementia">55 million people</a> around the world. A number of factors can increase a person’s risk of developing dementia, <a href="https://link.springer.com/article/10.14283/jpad.2023.119">including</a> high blood pressure, poor sleep, and physical inactivity. Meanwhile, keeping cognitively, physically, and socially active, and limiting alcohol consumption, can <a href="https://www.thelancet.com/article/S0140-6736(20)30367-6/fulltext">reduce the risk</a>. Recently, a <a href="https://alzres.biomedcentral.com/articles/10.1186/s13195-023-01308-4">large Swedish study</a> observed that chronic stress and depression were linked to a higher risk of developing <a href="https://alz-journals.onlinelibrary.wiley.com/doi/10.1002/alz.12638">Alzheimer’s disease</a>, the most common form of dementia. The researchers found people with a history of both chronic stress and depression had an even greater risk of the disease. Globally, around <a href="https://www.who.int/news-room/fact-sheets/detail/depression">280 million people</a> have depression, while roughly <a href="https://www.who.int/news-room/fact-sheets/detail/anxiety-disorders">300 million people</a> experience anxiety. With so many people facing mental health challenges at some stage in their lives, what can we make of this apparent link? <h2>What the study did and found</h2> This study examined the health-care records of more than 1.3 million people in Sweden aged between 18 and 65. Researchers looked at people diagnosed with chronic stress (technically chronic stress-induced exhaustion disorder), depression, or both, between 2012 and 2013. They compared them with people not diagnosed with chronic stress or depression in the same period. Participants were then followed between 2014 and 2022 to determine whether they received a diagnosis of mild cognitive impairment or dementia, in particular Alzheimer’s disease. <a href="https://alz-journals.onlinelibrary.wiley.com/doi/10.1016/j.jalz.2016.07.151">Mild cognitive impairment</a> is often seen as the precursor to dementia, although not everyone who has mild cognitive impairment will progress to dementia. During the study period, people with a history of either chronic stress or depression were around twice as likely to be diagnosed with mild cognitive impairment or Alzheimer’s disease. Notably, people with both chronic stress and depression were up to four times more likely to be diagnosed with mild cognitive impairment or Alzheimer’s disease. <h2>Important considerations</h2> In interpreting the results of this study, there are some key things to consider. First, the diagnosis of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9438479/">chronic stress-induced exhaustion disorder</a> is unique to the Swedish medical system. It is characterised by at least six months of intensive stress without adequate recovery. Symptoms include exhaustion, sleep disturbance and concentration difficulties, with a considerable reduction in ability to function. Mild stress may not have the same effect on dementia risk. Second, the number of people diagnosed with dementia in this study (the absolute risk) was very low. Of the 1.3 million people studied, 4,346 were diagnosed with chronic stress, 40,101 with depression, and 1,898 with both. Of these, the number who went on to develop Alzheimer’s disease was 14 (0.32%), 148 (0.37%) and 9 (0.47%) respectively. These small numbers may be due to a relatively young age profile. When the study began in 2012–2013, the average age of participants was around 40. This means the average age in 2022 was around 50. Dementia is typically diagnosed in <a href="https://www.health.gov.au/topics/dementia/about-dementia">people aged over 65</a> and diagnosis <a href="https://karger.com/dem/article-abstract/34/5-6/292/99009/Overdiagnosis-of-Dementia-in-Young-Patients-A?redirectedFrom=fulltext">in younger ages</a> may be less reliable. Finally, it’s possible that in some cases stress and depressive symptoms may reflect an awareness of an already declining memory ability, rather than these symptoms constituting a risk factor in themselves. This last consideration speaks to a broader point: the study is observational. This means it can’t tell us one thing caused the other – only that there is an association. <h2>What does other evidence say?</h2> <a href="https://link.springer.com/article/10.14283/jpad.2023.119">Many studies</a> indicate that significant symptoms of depression, anxiety and stress are related to higher dementia risk. However, the nature of this relationship is unclear. For example, are depressive and anxiety symptoms a risk factor for dementia, or are they consequences of a declining cognition? It’s likely to be a bit of both. High <a href="https://pubmed.ncbi.nlm.nih.gov/32082139/">depressive and anxiety symptoms</a> are commonly reported in people with mild cognitive impairment. However, studies in middle-aged or younger adults suggest they’re important dementia risk factors too. For example, similar to the Swedish study, other <a href="https://www.sciencedirect.com/science/article/pii/S0165032719323031">studies</a> have suggested people with a history of depression are twice as likely to develop dementia than those without this history. In addition, in middle-aged adults, high anxiety symptoms are associated with <a href="https://pubmed.ncbi.nlm.nih.gov/34648818/">poorer cognitive function</a> and <a href="https://bmjopen.bmj.com/content/8/4/e019399">greater dementia risk</a> in later life. <h2>Why the link?</h2> There are several potential pathways through which stress, anxiety and depression could increase the risk of dementia. Animal studies suggest cortisol (a hormone produced when we’re stressed) can increase risk of Alzheimer’s disease by causing the accumulation of key proteins, <a href="https://pubmed.ncbi.nlm.nih.gov/34159699/">amyloid and tau</a>, in the brain. The accumulation of these proteins can result in increased <a href="https://www.mdpi.com/1422-0067/23/18/10572">brain inflammation</a>, which affects the brain’s nerves and supporting cells, and can ultimately lead to brain volume loss and memory decline. Another potential pathway is through <a href="https://www.sciencedirect.com/science/article/pii/S1087079217300114?via%3Dihub">impaired sleep</a>. Sleep disturbances are common in people with chronic stress and depression. Similarly, people with Alzheimer’s disease commonly report sleep disturbances. Even in people with <a href="https://pubmed.ncbi.nlm.nih.gov/34668959/">early Alzheimer’s disease</a>, disturbed sleep is related to poorer memory performance. Animal studies suggest poor sleep can also enhance accumulation of <a href="https://pubmed.ncbi.nlm.nih.gov/31408876/">amyloid and tau</a>. We still have a lot to learn about why this link might exist. But evidence-based strategies which target chronic stress, anxiety and depression may also play a role in reducing the risk of dementia.<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/215065/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/yen-ying-lim-355185">Yen Ying Lim</a>, Associate Professor, Turner Institute for Brain and Mental Health, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> and <a href="https://theconversation.com/profiles/ivana-chan-1477100">Ivana Chan</a>, PhD candidate, clinical psychology, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Don’t believe the hype. Menopausal women don’t all need to check – or increase – their testosterone levels

<a href="https://theconversation.com/profiles/susan-davis-10376">Susan Davis</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> Ever heard “low testosterone” blamed for low mood, brain fog and loss of vitality? Despite all evidence to the contrary, social media influencers are increasingly promoting testosterone therapy as an elixir for women experiencing troubling symptoms of menopause. In a series of documentaries and <a href="https://www.dailymail.co.uk/health/article-11792553/Davina-McCall-effect-sparks-menopause-testosterone-treatment-rush-putting-women-risk.html">social media posts</a> about menopause in 2021 and 2022, British TV presenter Davina McCall promoted the use of testosterone therapy in addition to standard <a href="https://www.menopause.org.au/hp/information-sheets/combined-menopausal-hormone-therapy-mht">menopausal hormone therapy</a>. The “<a href="https://www.telegraph.co.uk/news/2023/02/17/davina-effect-fuels-surge-menopausal-women-using-testosterone/#:%7E:text=Chelsea%20Magazine%20Company-,'Davina%20effect'%20fuels%20surge%20in%20menopausal%20women%20using%20testosterone,NHS%20prescriptions%20for%20the%20hormone">Davina effect</a>” has helped fuel a <a href="https://pharmaceutical-journal.com/article/news/nhs-testosterone-prescribing-in-women-rises-ten-fold-in-seven-years#:%7E:text=The%20number%20of%20women%20in,The%20Pharmaceutical%20Journal%20has%20revealed">ten-fold increase</a> in prescribing of testosterone for women in the United Kingdom since 2015. Data isn’t available for Australia, but in my clinical practice, women are increasingly asking to have their testosterone level checked, and seeking testosterone to treat fatigue and brain fog. But while testosterone continues to be an important hormone before and after menopause, this doesn’t mean women should be having a blood test to get their testosterone levels checked – or taking testosterone therapy. <h2>What does testosterone do?</h2> Testosterone is an important hormone in women’s bodies, affecting the blood vessels, skin, muscle and bone, breast tissue and the brain. In both women and men, testosterone can act on its own or be converted into estrogen. Before menopause, testosterone is made in the ovaries, where it helps developing eggs grow and aids in estrogen production. The ovaries release both testosterone and estrogen into the bloodstream, and the levels of the two hormones in the blood peak around ovulation. Some of the testosterone measured in blood is also produced outside the ovaries, such as in fat, where it is made from “pre-hormones” secreted by the adrenal glands. This source of production of testosterone takes over after menopause. <h2>Do we have more testosterone before menopause?</h2> The claim is often made that pre-menopausal women have more testosterone in their bloodstream than estrogen, to justify the need for testosterone replacement after menopause. But, when sex hormones have been measured with precision, studies have shown this is not true. <a href="https://pubmed.ncbi.nlm.nih.gov/31390028/">Our research</a> found estrogen levels are higher than testosterone levels at all stages of the menstrual cycle. Blood testosterone levels <a href="https://pubmed.ncbi.nlm.nih.gov/31390028/">fall</a> by about 25% between the ages of 18 and 40 years in healthy women. The fall in testosterone coincides with the decline in eggs in the ovaries but whether this is a marker of the decline, a consequence, or a cause of the decline is not known. From around 40, the rate of decline slows and blood testosterone levels don’t change when <a href="https://www.menopause.org.au/hp/information-sheets/what-is-menopause">menopause</a> occurs naturally. Studies have not shown testosterone levels change meaningfully during the menopause transition. <h2>Can blood tests detect ‘low testosterone’?</h2> Some influencers claim to have a condition called “testosterone deficiency syndrome” or low levels of testosterone detected in blood tests. But there is no “normal” blood level below which a woman can be diagnosed as having “testosterone deficiency”. So there’s no such thing as having a testosterone deficiency or testosterone deficiency syndrome. This is also in part, because women have very low testosterone concentrations compared with men, and most commercial methods used to measure testosterone cannot separate normal from low levels in women with any certainty. Pre-menopausal women might also be told they have “low” testosterone if blood is drawn early in the menstrual cycle when it is normal for testosterone to be low. (However, it would only be clinically necessary to do this type of blood test to look for high testosterone, in someone with with excessive hair growth or severe acne, for example, not for low testosterone.) In post-menopausal women, much of the action of testosterone occurs in the tissues where it is made, after which testosterone is either converted to estrogen or broken down before it leaks back into the circulation. So blood testosterone concentrations are not a true reflection of tissue concentrations. Further complicating the picture is the enormous variability in the effects of testosterone. At a given blood level of testosterone, some women might have oily skin, acne, increased body hair growth or balding, while others will have no such effects. So, looking for a “low” blood testosterone in women is not helpful. <h2>Can testosterone improve sexual desire? What about other conditions?</h2> There is sound evidence that testosterone therapy may improve sexual desire in post-menopausal women who have developed low sexual desire that bothers them. This was <a href="https://www.tandfonline.com/doi/full/10.1080/13697137.2019.1637079">confirmed by</a> a <a href="https://pubmed.ncbi.nlm.nih.gov/31353194/">systematic review</a> of clinical trials comparing testosterone with a placebo or an alternative. These trials, all of which involved a treatment time of at least 12 weeks, showed testosterone therapy, overall, improved desire, arousal, orgasm and sexual satisfaction in post-menopausal women with low desire that caused them distress. Treatment is only indicated for women who want an improvement in sexual desire (after excluding other factors such as depression or medication side effects) and its success can only be determined by each woman’s personal self-reported response. But there is <a href="https://www.tandfonline.com/doi/full/10.1080/13697137.2019.1637079">not enough evidence</a> to show testosterone is beneficial for any other symptom or medical condition. The overall available data has shown no effect of testosterone on mood or cognition. As such, testosterone therapy <a href="https://www.tandfonline.com/doi/full/10.1080/13697137.2019.1637079">should not be used</a> to treat symptoms such as fatigue, low mood, muscle weakness and poor memory, or to prevent bone loss, dementia or breast cancer. However research continues to investigate these potential uses, including from my <a href="https://www.monash.edu/medicine/sphpm/units/womenshealth">research team</a>, which is investigating whether testosterone therapy can <a href="https://asbmr.onlinelibrary.wiley.com/doi/10.1002/jbmr.534">protect against bone density loss and muscle loss after menopause</a>.

How to increase the value of your home in one weekend

Increasing the value of your property pre-sale doesn’t have to require a team of professionals. Just one weekend dedicated to cleaning, refreshing, tidying and upgrading can put you in great stead for sales success. We asked the experts to reveal the best value-adding DIY projects to suit a short time frame and shoestring budget. 1. Refresh an old paint job There is no easier way to boost a property’s value than a new paint job, which can range from a one-room refresh, to an extensive repaint of the entire home. For homeowners low on budget and time, focus on painting the main living areas with Dulux’s Wash&Wear to disguise mismatched old paint, cracks and imperfections. “It’s great for interiors, especially in the matt finish. Even if the colours don’t entirely match, you can get away with it,” says Andrea Lucena-Orr, colour planning and communications manager at Dulux Australia. In terms of colour, white remains popular for appealing to a broad base of buyers. If painting an older property, opt for warmer whites such as Dulux Natural White or Antique White U.S.A ® Contemporary homes are more suited to cooler whites, with a grey or beige base, such as Dulux Lexicon ® or White on White. 2. Create a feature wall Painting a feature wall can be a valuable method for creating a point of difference on a minimal timeframe. This might be a dark single shade in the main bedroom or a bold dual-colour wall. “Feature walls, nooks and colour-blocking with tape are all ways to add interest,” says Lucena-Orr. When selecting colours for a feature wall, look for shades that will complement the room’s existing furniture and décor items. “Try using colours to highlight an artwork, a piece of furniture, or tie into the bed linen,” Lucena-Orr says. 3. Tidy the exterior If there is one area of the home you should focus on before a sale, it’s the exterior. While some homes will benefit from an entire façade repaint, updating this area can be achieved in a few quick jobs. Start by removing any cobwebs, cleaning the walls and filling in visible cracks. For added aesthetic appeal, paint some pots and place them near the front door, or spray paint a bench seat for the front porch. Painting the front door a colour such as cobalt or teal blue is another powerful tool for creating colour memories and attracting interest. “A teal door will help buyers remember the house. Even if buyers don’t like it, it’s quick and easy for them to change,” Lucena-Orr says. 4. Install storage shelves Installing open shelves in the kitchen, bathroom, laundry and study is a simple way to integrate more storage into a property, which never goes unappreciated. “Installing hooks, rails or racks to your doors will spruce things up without being too dramatic or involve any structural changes,” says Bunnings category manager – decorator, Sharyn Petrzela. “Pull-out baskets and base-mount slide-out baskets are also a great way to add storage and can be installed in a day.” 5. Outsource odd jobs Selling a home is stressful and time consuming. If budget allows, don’t be afraid to outsource tasks where you can. Websites such as Airtasker make it affordable to hire individuals for even the smallest household jobs, from removing weeds, to assembling furniture, collecting hard rubbish and hanging pictures. You might just want someone to focus on cleaning those detailed areas of the home such as the skirting boards, architraves, light fittings and door handles. 6. Add the finishing touches If you can’t afford a professional property stylist to decorate your home pre-sale, try these expert tips. “As a stylist, I think having decorative items (vases, candle holders and similar) that have a colour theme and style that is carried through the house gives a sense of flow that makes a house feel like a whole, instead of a series of different rooms,” says Sophie Kost, director and lead designer of My Beautiful Abode. Even small updates like replacing the feather inserts in your couch cushions can have a big impact on the feeling of a home. Remember to declutter surfaces and remove personal possessions in this process, as this allows buyers to better imagine themselves in the space. Image credits: Getty Images

Crypto scams will increase over the holidays – here’s what you need to know to not fall victim

Each year, as the festive season arrives, we must also keep an eye out for potential scammers trying to ruin the fun. This is because scammers become more active <a href="https://www.scamwatch.gov.au/scam-statistics?scamid=all&date=2021" target="_blank" rel="noopener">during the holidays</a>, targeting us while we have our guard down. So far in 2022, Australians have lost around <a href="https://www.scamwatch.gov.au/scam-statistics?scamid=all&date=2022" target="_blank" rel="noopener">half a billion dollars to scams</a>, which is already significantly more than had been lost by this time last year. The majority of these losses – <a href="https://www.scamwatch.gov.au/scam-statistics?scamid=26&date=2022" target="_blank" rel="noopener">around $300 million</a> – have involved investment or cryptocurrency scams. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/494108/original/file-20221108-14-vbvqlj.png?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/494108/original/file-20221108-14-vbvqlj.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/494108/original/file-20221108-14-vbvqlj.png?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=370&fit=crop&dpr=1 600w, https://images.theconversation.com/files/494108/original/file-20221108-14-vbvqlj.png?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=370&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/494108/original/file-20221108-14-vbvqlj.png?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=370&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/494108/original/file-20221108-14-vbvqlj.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=465&fit=crop&dpr=1 754w, https://images.theconversation.com/files/494108/original/file-20221108-14-vbvqlj.png?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=465&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/494108/original/file-20221108-14-vbvqlj.png?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=465&fit=crop&dpr=3 2262w" alt="A chart showing a steady rise of crypto scams, with a spike in April 2022" /></a><figcaption>Investment scams 2019-2022. scamwatch.gov.au</figcaption></figure> Researchers from <a href="https://cybercentre.org.au/" target="_blank" rel="noopener">Deakin University’s Centre for Cyber Security Research and Innovation</a> had a opportunity to interview recent victims of these scams.

If it sounds too good to be true, it might just be a scam <blockquote> I was dumbfounded, to say that ground shattered under my feet would be an understatement, it will take me a very long time to recover from it, financially and mentally. – (36-year-old female, legal practitioner from Victoria) </blockquote> Most crypto scams involve getting the victim to buy and send cryptocurrency to the perpetrator’s account for what appears to be a legitimate investment opportunity. Cryptocurrency is the currency of choice for this type of crime, because it’s unregulated, untraceable and transactions cannot be reversed. Victims of such scams are targeted using a number of different methods, which include: Investment scams: scammers pretend to be investment managers claiming high returns on crypto investments. They get the victim to transfer over funds and escape with them. “Pump and dump”: scammers usually hype up a new cryptocurrency or an <a href="https://www.kaspersky.com/resource-center/preemptive-safety/how-to-avoid-nft-scams" target="_blank" rel="noopener">NFT project</a> and artificially increase its value. Once enough victims invest, the scammers sell their stake, leaving the victims with worthless cryptocurrency or NFT. Romance scams: involves scammers using dating platforms, social media or direct messaging to engage with you, gain your trust and pitch an amazing investment opportunity promising high returns, or ask for cryptocurrency to cover medical or travel expenses. Phishing scams: an old but still effective scam involving malicious emails or messages with links to fake websites promising huge returns on investment or just outright stealing credentials to access users’ digital currency wallets. Ponzi schemes: a type of investment scam where the scammers use cryptocurrency gathered from multiple victims to repay high interest to some of them; when victims invest more funds, the scammers escape with all the investments. Mining scams: scammers try and convince victims to buy cryptocurrency to use in mining more of it, while in reality there is no mining happening – the scammers just make transfers that look like returns on the investment. Over time, the victim invests more, and the scammers keep taking it all. Although methods evolve and change, the telltale signs of a potential scam remain relatively similar: <ul> <li>very high returns with promises of little or no risk</li> <li>proprietary or secretive strategies to gain an advantage</li> <li>lack of liquidity, requiring a minimum accumulation amount before funds are released.</li> </ul> Where to seek help if you’ve been scammed <blockquote> I felt helpless, I didn’t know what to do, who to reach out to, I was too embarrassed and just kept blaming myself. – (72-year-old male, accountant from Victoria) </blockquote> If you think you have fallen victim to one of these scams, here is what you need to do next: <ul> <li> inform the Australian Competition and Consumer Commission (ACCC) <a href="https://www.scamwatch.gov.au/report-a-scam" target="_blank" rel="noopener">here</a> or reach out to relevant authorities <a href="https://www.scamwatch.gov.au/get-help/where-to-get-help" target="_blank" rel="noopener">as per advice on the ScamWatch website</a> </li> <li> reach out to your friends and family members and inform them of the scam; they can also be a source of help and support during such times </li> <li> as these events can have a psychological impact, it’s recommended you talk to your GP, a health professional, or someone you trust </li> <li> you can also reach out to counselling services such as <a href="http://www.lifeline.org.au/" target="_blank" rel="noopener">LifeLine</a>, <a href="https://www.beyondblue.org.au/" target="_blank" rel="noopener">beyond blue</a>, <a href="http://www.suicidecallbackservice.org.au/" target="_blank" rel="noopener">Sucide Call Back Service</a>, <a href="http://www.mensline.org.au/" target="_blank" rel="noopener">Mens Line</a>, and <a href="https://www.scamwatch.gov.au/get-help/where-to-get-help" target="_blank" rel="noopener">more</a> for help and support. </li> </ul> If you ever find yourself in a difficult situation, please remember help and support is available.

Does picking your nose really increase your risk of dementia?

No matter your age, we all pick our nose. However, if gripping headlines around the world are a sign, this habit could increase your risk of Alzheimer’s disease, the most common form of dementia. One international news report <a href="https://www.the-sun.com/health/6565520/common-habit-increase-risk-alzheimers-dementia/">said</a>: <blockquote> ‘SCARY EVIDENCE’ How a common habit could increase your risk of Alzheimer’s and dementia </blockquote> Another <a href="https://www.mirror.co.uk/news/health/alzheimers-disease-risk-increased-picking-28378042">ran with</a>: <blockquote> Alzheimer’s disease risk increased by picking your nose and plucking hair, warns study </blockquote> An Australian news article <a href="https://www.sbs.com.au/news/article/could-picking-your-nose-lead-to-dementia-australian-researchers-are-digging-into-it/rn7xqef2w">couldn’t resist a pun</a>: <blockquote> Could picking your nose lead to dementia? Australian researchers are digging into it. </blockquote> Yet if we look at the research study behind these news reports, we may not need to be so concerned. The evidence connecting nose picking with the risk of dementia is still rather inconclusive. What prompted these headlines? Queensland researchers published <a href="https://www.nature.com/articles/s41598-022-06749-9">their study</a> back in February 2022 in the journal Scientific Reports. However, the results were not widely reported in the media until about eight months later, following a <a href="https://news.griffith.edu.au/2022/10/28/new-research-suggests-nose-picking-could-increase-risk-for-alzheimers-and-dementia/">media release</a> from Griffith University in late October. The media release had a similar headline to the multiple news articles that followed: <blockquote> New research suggests nose picking could increase risk for Alzheimer’s and dementia </blockquote> The media release clearly stated the research was conducted in mice, not humans. But it did quote a researcher who described the evidence as “potentially scary” for humans too. What the study did The researchers wanted to learn more about the role of Chlamydia pneumoniae bacteria and Alzheimer’s disease. These bacteria have been found in brains of people with Alzheimer’s, although <a href="https://academic.oup.com/femspd/article/48/3/355/506227?login=true">the studies</a> were completed more than <a href="https://doi.org/10.1007/s004300050071">15 years ago</a>. This bacteria species can cause respiratory infections such as pneumonia. It’s not to be confused with the chlamydia species that causes sexually transmitted infections (that’s C. trachomatis). The researchers were interested in where C. pneumoniae went, how quickly it travelled from the nose to the brain, and whether the bacteria would create a hallmark of Alzheimer’s disease found in brain tissue, the amyloid β protein. So they conducted a small study in mice. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/493175/original/file-20221103-22-znvia5.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/493175/original/file-20221103-22-znvia5.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/493175/original/file-20221103-22-znvia5.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=432&fit=crop&dpr=1 600w, https://images.theconversation.com/files/493175/original/file-20221103-22-znvia5.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=432&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/493175/original/file-20221103-22-znvia5.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=432&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/493175/original/file-20221103-22-znvia5.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=543&fit=crop&dpr=1 754w, https://images.theconversation.com/files/493175/original/file-20221103-22-znvia5.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=543&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/493175/original/file-20221103-22-znvia5.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=543&fit=crop&dpr=3 2262w" alt="White mouse in open cage with raised nose" /></a><figcaption>The study, which was conducted in mice, didn’t mention nose picking. <a class="source" href="https://www.shutterstock.com/image-photo/funny-curious-white-rat-looking-out-402796495">Shutterstock</a></figcaption></figure> The researchers injected C. pneumoniae into the noses of some mice and compared their results to other mice that received a dose of salty water instead. They then waited one, three, seven or 28 days before euthanising the animals and examined what was going on in their brains. What the study found Not surprisingly, the researchers detected more bacteria in the part of the brain closest to the nose in mice that received the infectious dose. This was the olfactory brain region (involved in the sense of smell). Mice that had the bacteria injected into their noses also had clusters of the amyloid β protein around the bacteria. Mice that didn’t receive the dose also had the protein present in their brains, but it was more spread out. The researchers didn’t compare which mice had more or less of the protein. Finally, the researchers found that gene profiles related to Alzheimer’s disease were more abundant in mice 28 days after infection compared with seven days after infection. How should we interpret the results? The study doesn’t actually mention nose-picking or plucking nose hairs. But the media release quoted one of the researchers <a href="https://news.griffith.edu.au/2022/10/28/new-research-suggests-nose-picking-could-increase-risk-for-alzheimers-and-dementia/">saying</a> this was not a good idea as this could damage the nose: <blockquote> If you damage the lining of the nose, you can increase how many bacteria can go up into your brain. </blockquote> The media release suggested you could protect your nose (by not picking) and so lower your risk of Alzheimer’s disease. Again, this was not mentioned in the study itself. At best the study results suggest infection with C. pneuomoniae can spread rapidly to the brain – in mice. Until we have more definitive, robust studies in humans, I’d say the link between nose picking and dementia risk remains low. – Joyce Siette <hr /> Blind peer review Nose picking is a life-long common human practice. <a href="https://pubmed.ncbi.nlm.nih.gov/7852253/">Nine in ten people</a> admit doing it. By the age of 20, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6345537/">some 50% of people</a> have evidence of C. pneumoniae in their blood. That rises to 80% in people aged 60-70. But are these factors connected? Does one cause the other? The study behind these media reports raises some interesting points about C. pneumoniae in the nasal cavity and its association with deposits of amyloid β protein (plaques) in the brain of mice – not humans. We cannot assume what happens in mice also applies to humans, for a number of reasons. While C. pneumoniae bacteria may be <a href="https://academic.oup.com/femspd/article/48/3/355/506227?login=true">more common</a> in people with late-onset Alzheimer’s disease, association with the hallmark amyloid plaques in the mouse study does not necessarily mean one causes the other. The mice were also euthanised at a maximum of 28 days after exposure, long before they had time to develop any resultant disease. This is not likely anyway, because mice do not naturally get Alzheimer’s. Even though mice can accumulate the plaques associated with Alzheimer’s, they <a href="https://www.nature.com/articles/d41586-018-07484-w#:%7E:text=Alzheimer's%20is%20marked%20by%20cognitive,not%20occur%20naturally%20in%20mice">do not display</a> the memory problems seen in people. Some researchers have also argued that amyloid β protein deposits in animals are different to humans, and therefore <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2813509/">might not be suitable</a> for comparison. So what’s the verdict? Looking into risk factors for developing Alzheimer’s is worthwhile. But to suggest picking your nose, which introduces C. pneumoniae into the body, may raise the risk of Alzheimer’s in humans – based on this study – is overreach. – Mark Patrick Taylor<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/193463/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> Writen by Joyce Siette.

Cold homes increase the risk of severe mental health problems – new study

Concerns about <a href="https://theconversation.com/energy-crisis-the-uk-is-still-heading-for-widespread-fuel-poverty-despite-the-governments-price-cap-190290" target="_blank" rel="noopener">fuel poverty</a> and people not being able to heat their homes adequately are not new in the UK, but these worries have been <a href="https://www.theguardian.com/uk-news/2022/oct/26/warm-banks-open-wolverhampton-cost-of-living-crisis" target="_blank" rel="noopener">heightened</a> by significant increases in energy costs and the <a href="https://theconversation.com/the-cost-of-living-crisis-has-been-many-years-in-the-making-but-politicians-on-both-sides-ignore-this-189483" target="_blank" rel="noopener">cost-of-living crisis</a>. And as winter approaches, things are about to get a lot worse. Despite a relatively mild climate, the UK has higher levels of excess winter deaths – deaths associated with cold weather – than <a href="https://linkinghub.elsevier.com/retrieve/pii/S0140673614621140" target="_blank" rel="noopener">many colder countries</a>. This greater exposure to cold, despite milder weather, is related to poor housing quality, the high cost of heating homes and poverty. We know quite a lot about how living in a home that you can’t keep warm enough affects your physical health. Colder temperatures <a href="https://www.instituteofhealthequity.org/resources-reports/the-health-impacts-of-cold-homes-and-fuel-poverty/the-health-impacts-of-cold-homes-and-fuel-poverty.pdf" target="_blank" rel="noopener">suppress the immune system</a>, for example. But we know relatively little about the effects on mental health. <a href="https://doi.org/10.1016/j.socscimed.2022.115461" target="_blank" rel="noopener">Our new research</a> shows that living in a cold home is a significant mental health risk. Living in a cold home can affect your mental health in several ways. For many, heating costs are a source of stress and financial strain. Not being able to keep your home and family comfortably warm reduces feelings of control and autonomy over your environment. People who are unable to heat their home often adopt coping mechanisms that <a href="https://onlinelibrary.wiley.com/doi/10.1111/j.1365-2524.2005.00558.x" target="_blank" rel="noopener">limit socialising</a> – for example, not inviting friends over and going to bed early to keep warm. And many people are just worn down by the drudgery of a whole winter of being uncomfortably cold. Using <a href="https://www.understandingsociety.ac.uk/" target="_blank" rel="noopener">data</a> from a large representative sample of adults in the UK, we followed people over many years and tracked the effect of being unable to keep your home warm on mental health. When people’s homes became cold, their risk of severe mental distress significantly increased. For people who previously had no mental health problems, the odds of severe mental distress doubled when they had a cold home, while for those who had some (but not severe) mental health symptoms, the risk tripled (see chart below). We found these effects even after taking into account many other factors associated with mental health, including income. Odds of reporting severe mental distress following transition into cold housing compared to those who remained in warm homes <figure class="align-center "><img src="https://images.theconversation.com/files/492381/original/file-20221028-61968-sxkqgr.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/492381/original/file-20221028-61968-sxkqgr.png?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=483&fit=crop&dpr=1 600w, https://images.theconversation.com/files/492381/original/file-20221028-61968-sxkqgr.png?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=483&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/492381/original/file-20221028-61968-sxkqgr.png?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=483&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/492381/original/file-20221028-61968-sxkqgr.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=607&fit=crop&dpr=1 754w, https://images.theconversation.com/files/492381/original/file-20221028-61968-sxkqgr.png?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=607&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/492381/original/file-20221028-61968-sxkqgr.png?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=607&fit=crop&dpr=3 2262w" alt="" /><figcaption>author provided</figcaption></figure> Sadly, the risk of living in a cold home differs greatly across the UK population. Lone parents and people who are unemployed or long-term sick are much more likely to live in cold homes. There is also significant inequality across ethnic groups – more than 12% of black people live in cold homes compared with under 6% of white British people, for example. Those who rent rather than own their home are also far more likely to live in cold homes, for social renters this is despite the, on average, <a href="https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/1088447/EHS_Housing_quality_and_condition_report_2020.pdf" target="_blank" rel="noopener">higher quality and</a><a href="https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/1091144/Energy_Report_2020_revised.pdf" target="_blank" rel="noopener">efficiency</a> of social rented homes. Putting on another jumper won’t be enough to get many in the UK through the coming winter. And mental health distress is just one consequence. Cold homes cause issues with significant personal and societal costs – from individual health effects to the increased pressure on the NHS, as well as broader economic loss due to missed work. Rishi Sunak’s new government needs to help people live in adequately warm homes this winter. But how? The older age of housing in the UK is <a href="http://www.instituteofhealthequity.org/projects/the-health-impacts-of-cold-homes-and-fuel-poverty" target="_blank" rel="noopener">heavily implicated</a> in the UK’s high levels of cold. Support for energy efficiency improvements is therefore a possible means of reducing cold homes. This will also mean tackling the so-called “split incentive” in the private rented sector, which houses a significant proportion of households. The split incentive refers to the challenge of the benefits of improvements not being experienced by the property owners but by tenants, reducing the incentive for owners to invest. This results in poorer quality and more expensive homes for renters. Heat or eat? Most can’t afford either The high proportion of cold homes in the social housing sector – despite having the best average energy efficiency due to insulation and building types (flats) – shows that energy efficiency improvements alone will not eliminate cold. <a href="https://www.resolutionfoundation.org/publications/the-living-standards-outlook-2022/" target="_blank" rel="noopener">Incomes in the UK are falling</a>. Benefit levels are <a href="https://theconversation.com/raising-benefits-in-line-with-earnings-will-make-the-poor-worse-off-heres-why-192880" target="_blank" rel="noopener">painfully low</a> and worsened by policies including the benefit cap, two-child limit and sanctions. Years of cuts and <a href="https://www.jrf.org.uk/file/59072/download?token=acsEgZp7&filetype=briefing" target="_blank" rel="noopener">below inflation rises</a> mean that the term “heat or eat”, used to describe difficult spending decisions for low-income households, is now out of date, as <a href="https://www.jrf.org.uk/file/59191/download?token=PCFIM8W9&filetype=briefing" target="_blank" rel="noopener">many can afford neither</a>. The combination of low household incomes with surging energy costs has created devastating pressure on household budgets. While the energy cap has limited energy cost increases below the worst estimates, energy bills have still <a href="https://theconversation.com/energy-crisis-the-uk-is-still-heading-for-widespread-fuel-poverty-despite-the-governments-price-cap-190290" target="_blank" rel="noopener">more than doubled in the past year</a>. And prepayment meters mean that those the with the least end up paying the most. There are, therefore, many areas for potential government intervention, and clear evidence that failing to intervene will cause harm to health.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/193125/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> Writen by Amy Clair.

Being stressed out before you get COVID increases your chances of long COVID. Here’s why

Stress is part and parcel of modern life. When we’re on the verge of a new challenge or a significant event, we can experience stress mixed with excitement and a sense of challenge. This form of “good” stress, or <a href="https://www.verywellmind.com/what-you-need-to-know-about-eustress-3145109" target="_blank" rel="noopener">eustress</a>, is important for growth, development, and achievement. However, prolonged stress and overwhelming or traumatic events can negatively impact our health. These forms of “bad” stress – or distress – can make us sick, depressed, anxious and over the long term, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3341916/" target="_blank" rel="noopener">increase our risk</a> of heart disease, stroke, type 2 diabetes, dementia and even <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6877941" target="_blank" rel="noopener">cancer</a>. Distress can also affect our ability to <a href="https://medlineplus.gov/postcovidconditionslongcovid.html" target="_blank" rel="noopener">fully recover</a> from COVID. Ongoing symptoms for a month or more is referred to as long COVID. Those affected can experience fatigue, brain fog, shortness of breath, loss of taste and smell, difficulty sleeping, anxiety and/or depression. For some, these symptoms can last for many months or even years, making it impossible to return to pre-COVID life. In a <a href="https://jamanetwork.com/journals/jamapsychiatry/fullarticle/2796097" target="_blank" rel="noopener">Harvard University study</a> published last month, people suffering psychological distress in the lead up to their COVID infection had a greater chance of experiencing long COVID. The researchers found those with two types of distress (depression, probable anxiety, perceived stress, worry about COVID, and loneliness) had an almost 50% greater risk of long COVID than other participants. So how might distress impact the body’s ability to fight infection? First, we need to look at inflammation <a href="https://stories.uq.edu.au/imb/the-edge/inflammation/what-is-inflammation/index.html" target="_blank" rel="noopener">Inflammation</a> is the body’s way of responding to an infection or injury. When the <a href="https://medlineplus.gov/ency/article/000821.htm" target="_blank" rel="noopener">immune system</a> encounters a virus, for example, it launches an attack to neutralise infected cells and store a memory of that virus so it can respond faster and more effectively the next time. Many things can cause inflammation, including bacteria and viruses, injuries, toxins and chronic stress. The body has many different responses to inflammation, including redness, heat, swelling and pain. Some inflammatory responses can occur silently within the body, without any of these typical symptoms. At other times, inflammation can mobilise energy resources to cause exhaustion and fever. During inflammation, immune cells release substances known as inflammatory mediators. These chemical messengers cause small blood vessels to become wider (dilate), allowing more blood to reach injured or infected tissue to help with the healing process. This process can also irritate nerves and cause pain signals to be sent to the brain. What does distress have to do with inflammation? In the short term, stress <a href="https://newsinhealth.nih.gov/2021/01/feeling-stressed" target="_blank" rel="noopener">causes</a> the release of hormones that suppress inflammation, ensuring the body has enough energy resources available to respond an immediate threat. However, when experienced over an extended period of time, stress itself can cause low grade “silent” inflammation. Chronic distress and related mental health conditions such as anxiety and depression, are all associated with elevated levels of inflammatory mediators. In fact, the repeated exposure to mild, unpredictable stress is enough to elicit an inflammatory response. <figure class="align-center "><img src="https://images.theconversation.com/files/490261/original/file-20221018-15212-eoxhg1.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/490261/original/file-20221018-15212-eoxhg1.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=400&fit=crop&dpr=1 600w, https://images.theconversation.com/files/490261/original/file-20221018-15212-eoxhg1.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=400&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/490261/original/file-20221018-15212-eoxhg1.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=400&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/490261/original/file-20221018-15212-eoxhg1.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=503&fit=crop&dpr=1 754w, https://images.theconversation.com/files/490261/original/file-20221018-15212-eoxhg1.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=503&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/490261/original/file-20221018-15212-eoxhg1.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=503&fit=crop&dpr=3 2262w" alt="Fatigued woman rests her head against a wall" /><figcaption>Repeated exposure to stress can produce an inflammatory response. <a class="source" href="https://unsplash.com/photos/pV_ixbLn4QU" target="_blank" rel="noopener">Stacey Garrielle Koenitz Rozells/Unsplash</a></figcaption></figure> Pre-clinical (lab-based) <a href="https://www.nature.com/articles/mp2013155" target="_blank" rel="noopener">studies</a> have shown chronic mild stress can cause depression-like behaviour by promoting inflammation, including activating immune cells in the brain (microglia). When anti-inflammatories were given during the mild stress exposure they prevented depression-like behaviour. However if given after the event, the anti-inflammatories were ineffective. When inflammation is ongoing, such as with extended periods of distress, the immune system changes the way it responds by reprogramming the immune cells. Effectively, it switches to “low surveillance mode”. In this way, it remains active throughout the body, but downgrades its responsiveness to new threats. Because of this, the response may be slower and less effective. Consequently, the process of recovery can take longer. For a virus like COVID, it’s possible that prior exposure to distress may similarly impair the body’s ability to fight the infection and increase the risk of long COVID. How might distress affect recovery from COVID? There is still much to learn about how COVID infection affects the body and how psychological factors can impact clinical outcomes in the short and long term. COVID has far-reaching effects across multiple body systems, affecting the lungs and heart to the greatest degree, and increasing the risk of blood clotting and stroke. Because the virus resides within human cells, an immune system switched to “low surveillance mode” as a result of psychological distress may miss early opportunities to destroy infected tissues. The virus can then gain an advantage over the defence (immune) system. Conversely, distress can suppress the early response, tipping the balance in favour of the invader. <figure class="align-center "><img src="https://images.theconversation.com/files/490269/original/file-20221018-23-yyoxhq.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/490269/original/file-20221018-23-yyoxhq.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=411&fit=crop&dpr=1 600w, https://images.theconversation.com/files/490269/original/file-20221018-23-yyoxhq.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=411&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/490269/original/file-20221018-23-yyoxhq.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=411&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/490269/original/file-20221018-23-yyoxhq.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=516&fit=crop&dpr=1 754w, https://images.theconversation.com/files/490269/original/file-20221018-23-yyoxhq.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=516&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/490269/original/file-20221018-23-yyoxhq.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=516&fit=crop&dpr=3 2262w" alt="Man sits on a ledge over a busy street" /><figcaption>An immune system already switched to low surveillance mode might miss early opportunities to destroy the virus. <a class="source" href="https://unsplash.com/photos/kFVmYjK6hZ8" target="_blank" rel="noopener">Whoislimos/Unsplash</a></figcaption></figure> So what can we do about it?

Knowledge of this two-directional link is the first critical step to improving clinical outcomes. A lifestyle medicine approach that helps to reduce levels of distress and address mental health symptoms has important downstream benefits for physical health. This is likely to not only be the result of direct effects on the immune system itself, but also through related <a href="https://journals.sagepub.com/doi/10.1177/15598276221084250" target="_blank" rel="noopener">improvements in health behaviours</a> such as diet, exercise and/or sleep. Further research is needed to better understand the impact of distress on the immune system, mental health and COVID outcomes, and to highlight ways to intervene to prevent long COVID and support recovery.

Leaked email advises landlords to increase rent amid housing crisis

A real estate agency in Brisbane has come under fire over a leaked email in which landlords were advised to consider raising rents by more than 20 percent amid Australia’s worsening rental crisis. The email, sent by Ray White East End, asked landlords to consider whether their properties were being “under-rented” and advised them to increase rents by “above 20 percent” - more than double the rate of inflation - with potential earnings of an extra $10,000 a year. “Our property managers have been reviewing all our lease renewals and on average recommending a 17% rent increase on the leases renewed in October & November this year,” the email said, per <a href="https://www.theguardian.com/australia-news/2022/oct/17/brisbane-real-estate-agency-advises-landlords-to-increase-rents-by-over-20-amid-housing-crisis" target="_blank" rel="noopener">The Guardian</a>. “As we are planning December lease renewals, the average lease renewal recommendation is above 20%. This can be as much as $10,000 per year in additional rental income.” The agency said that “many landlords are not being provided with the information to make an informed decision” about rent increases, claiming that landlords were being advised to sign long-term leases with increases of $5 to $20 a week. The email also said that most tenants “are agreeable” to the increases and would understand that it is “fair and reasonable” based on what is available on the market. “On average, apartments in West End/Highgate Hill/South Brisbane/Brisbane CBD are renting for one bedroom $480 to $520+ [a week and for] two bedrooms $675 to $850+ [a week],” the email said. “If you are not achieving these rents (at a minimum), you should be asking why?” It comes as the Queenlsand government prepares to hold a housing summit to address rising homlessness and rental stress across the state. Penny Carr, the chief executive at advocacy organisation Tenants Queensland, said the email was an example of “opportunistic price-gouging” that is happening across Australia at the moment. “Rents are unaffordable for people at the moment and tenants are having to absorb increases because of fear of not finding another property or becoming homeless,” she said. “We should only allow rent increases above CPI if they’re justifiable and there’s been major work to the property or something’s had to be replaced.” Ms Carr said rent increases have been due to vacancy rates and supply and demand, and that the email dispels the myth that a land tax proposed by the government last year for interstate investors is to blame. Meanwhile, Ray White East End principal realtor Luke O’Kelly said rental affordability relies on investors. “Over the past 12 months, Brisbane has had some of the strongest population growth in the country and this has most clearly shown up in rental growth,” Mr O’Kelly said. “Right now, Brisbane doesn’t have enough homes for those that want to live here … with rents rising so quickly, Brisbane needs more property investors.” Fiona Caniglia, executive director of not-for-profit housing and homelessness organisation Q Shelter, said the timing of the email couldn’t be worse. “It is disappointing to hear this the week of the emergency housing summit to be honest,” she told <a href="https://www.news.com.au/finance/real-estate/renting/dont-have-enough-homes-rental-agency-ray-white-tries-to-increase-rent-by-20-per-cent/news-story/e4ff2ab4807fffe3b50b90fe81069156" target="_blank" rel="noopener">news.com.au</a>. “We already know that many vulnerable Queenslanders are struggling to secure a rental property in the first place.” “There are record numbers of people showing up for the small number of properties listed right across Queensland. Such an increase will only benefit those on higher incomes and will of course again negatively affect vulnerable Queenslanders, forcing more people into homelessness.” Ray White’s chief economist Nerida Conisbee defended the email in a statement shared with the outlet, saying that the market is currently ideal for investors. “Right now, Brisbane doesn’t have enough homes for those that want to live here,” she said. “This is making it tough for renters but does make it a good place to invest. While red hot house price growth is unlikely to start up again in the near future, yields are increasing as rents rise.” With Australians paying an extra $7.1 billion in rent over the past year and the average renter spending $62 more a week than this time last year, Greens housing and homelessness spokesperson Max Chandler-Mather said the email showed that urgent action is needed. “It’s this sort of flagrant price-gouging that demonstrates exactly why we need a national two-year freeze on rent increases,” he said.

Rent crisis? Average rents are increasing less than you might think

You wouldn’t know it from the pages of our daily newspapers, but the rate of growth in rents has been pretty modest. Not everywhere, not for everyone, but for most Australians who rent. According to the most recent count used by the Bureau of Statistics to compile the consumer price index, rents increased by only <a href="https://www.abs.gov.au/statistics/economy/price-indexes-and-inflation/consumer-price-index-australia/latest-release#overview" target="_blank" rel="noopener">1.6%</a> in the year to June. By comparison, wages climbed <a href="https://www.abs.gov.au/statistics/economy/price-indexes-and-inflation/wage-price-index-australia/latest-release" target="_blank" rel="noopener">2.6%</a>. Higher increases in other prices pushed the overall consumer price index up <a href="https://www.abs.gov.au/statistics/economy/price-indexes-and-inflation/consumer-price-index-australia/latest-release" target="_blank" rel="noopener">6.1%</a>. Rent decreases during COVID mean that over the past five years the total increase has been just 1.5%. Average rents are barely any higher than they were at the start of COVID. <hr /> <iframe id="GnFV0" class="tc-infographic-datawrapper" style="border: initial none initial;" src="https://datawrapper.dwcdn.net/GnFV0/2/" width="100%" height="400px" frameborder="0"></iframe> <hr /> The Bureau gets its data direct from the computers of real estate agents, state housing authorities and the Department of Defence (for Darwin). It covers rent actually paid, for a “<a href="https://www.abs.gov.au/statistics/detailed-methodology-information/concepts-sources-methods/consumer-price-index-concepts-sources-and-methods/2018/price-collection" target="_blank" rel="noopener">matched sample</a>” of dwellings, meaning it refers to the same dwellings each quarter so as to record genuine price changes. Actual versus advertised rents In contrast, the media (and some <a href="https://everybodyshome.com.au/resources/housing-criticalthe-role-of-housing-in-solving-critical-skill-shortages-across-the-regions/" target="_blank" rel="noopener">interest groups</a>) prefer to focus on the data for “advertised” or asking rents. These have been growing more strongly than the overall mass of rents paid. Nationwide, advertised rents climbed <a href="https://www.corelogic.com.au/news-research/news/2022/residential-rents-hit-record-highs-as-national-vacancy-rates-plummet" target="_blank" rel="noopener">8.2%</a> in the year to June, and by almost 18% over the five years to June on CoreLogic’s data. But advertised rents are only a tiny fraction of the rents actually paid. Not all properties get advertised. Advertised rents don’t always match up with the agreed rent. Most renters remain on existing contracts. Although advertised rents might be expected to relate to overall rents over time, they are not necessarily representative of the entire market. Our main concern ought to be what has happened to low-income renters. Low increases for low-income renters Australia’s lowest-income renters receive rent assistance, which is pretty frugal. Single renters get no more than <a href="https://www.servicesaustralia.gov.au/how-much-rent-assistance-you-can-get?context=22206" target="_blank" rel="noopener">$73 a week</a>, and very large families up to $97. But the typical rent paid by Australians on rent assistance hasn’t increased much. Over the year to June, the median rent for rent assistance recipients climbed by 1% – roughly $5 per week. Over the past five years it has increased 9% – somewhat less than the increase in the consumer price index of 10.7%. Over the longer term, low-income rents have increased more sharply. Households in the bottom 40% of income distribution used to spend around 22% of their after-tax income on rent, and now spend about 30%, down from a peak of 32%. <hr /> <iframe id="pRiMR" class="tc-infographic-datawrapper" style="border: initial none initial;" src="https://datawrapper.dwcdn.net/pRiMR/2/" width="100%" height="400px" frameborder="0"></iframe> <hr /> If there is a crisis in rents, the figures suggest it is not widespread. Rents in locations including Perth and Darwin are climbing much more strongly than others as they come off long periods of negative rent growth. The growth in asking rents is most pronounced away from the cities, in particular in holiday and tree-change destinations such as Richmond-Tweed (including Byron Bay), Gold Coast, Sunshine Coast and Wide Bay. Some were experiencing strong growth in asking rents before COVID, which accelerated through COVID. <hr /> <iframe id="JMbb7" class="tc-infographic-datawrapper" style="border: initial none initial;" src="https://datawrapper.dwcdn.net/JMbb7/2/" width="100%" height="400px" frameborder="0"></iframe> <hr /> Other regions, including parts of Sydney and Melbourne, have experienced subdued or <a href="https://www.abs.gov.au/statistics/economy/price-indexes-and-inflation/consumer-price-index-australia/latest-release#overview" target="_blank" rel="noopener">negative</a> growth. Across all renting households we are yet to see any serious growth. To date, the “rent crisis” has been felt mainly in a few specific locations and among people looking for new rental properties.<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/189154/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/ben-phillips-98866" target="_blank" rel="noopener">Ben Phillips</a>, Associate Professor, Centre for Social Research and Methods, Director, Centre for Economic Policy Research (CEPR), <a href="https://theconversation.com/institutions/australian-national-university-877" target="_blank" rel="noopener">Australian National University</a> This article is republished from <a href="https://theconversation.com" target="_blank" rel="noopener">The Conversation</a> under a Creative Commons license.

REX airline set to increase its fares

The soaring petrol prices will now affect our travel plans with one airline increasing its fares to keep up with the operational demand. Regional airline REX will put their fares up by $10 with some lower priced fares being slapped with a higher rate. REX’s general manager of network strategy Warrick Lodge said the price hike will begin from March 25. “With fuel prices shooting up by over 30 per cent in recent weeks and with supply chains being severely disrupted, the existing ticket prices are no longer tenable,” he said. Mr Lodge did assure customers that flights will remain affordable. “Rex’s Business class starts from $299 and is often even cheaper than Qantas’ economy class which can well exceed $500, particularly during periods not competing directly with Rex,” he said. “We will be bringing in additional aircraft shortly and more major cities in Australia will be able to benefit from Rex’s reliable and affordable air travel.” The inflation is the first one in almost three years for the airline.

Rapidly increasing climate change poses a rising threat to mental health

Climate change poses serious risks to mental well-being. For the first time, a <a href="https://www.ipcc.ch/report/sixth-assessment-report-working-group-ii/">new climate report</a> by the Intergovernmental Panel on Climate Change (IPCC) has assessed how climate change is having widespread and cumulative effects on mental health globally. Over the past decade, research and public interest on the effects of climate change on mental health have been increasing, as the number of individuals and communities exposed and vulnerable to climate change hazards grows. Weather and climate extremes such as storms, floods, droughts, heat events and wildfires can be traumatic and have immediate impacts on mental health. Slow onset events like changing seasonal and environmental norms, sea level rise and ice patterns can also affect people’s mental well-being. Growing evidence confirms that the consequences of rapid, widespread and pervasive climate events may include <a href="https://doi.org/10.1016/j.janxdis.2020.102263">anxiety</a>, <a href="https://changingclimate.ca/health-in-a-changing-climate/chapter/4-0/">PTSD</a>, <a href="https://doi.org/10.1038/s41558-018-0222-x">higher rates of suicide</a>, <a href="https://doi.org/10.1016/j.janxdis.2020.102237">a diminished sense of well-being (stress, sadness)</a>, <a href="https://doi.org/10.1016/S2542-5196(20)30144-3">ecological grief</a>, a rise in domestic violence, <a href="https://doi.org/10.1186/s12889-015-1874-3">cultural erosion</a> and diminished social capital and social relations. As scientists who contributed to the latest IPCC report <a href="https://www.ipcc.ch/report/sixth-assessment-report-working-group-ii/">Climate Change 2022: Impacts, Adaptation and Vulnerability</a>, we are pleased that this Sixth Assessment Report (AR6) assesses climate change impacts on mental health for the first time in detail, representing a major advancement and new contribution. <h2>Significant threats</h2> The Earth will <a href="https://www.ipcc.ch/report/sixth-assessment-report-working-group-i/">likely reach 1.5 C of warming above pre-industrial levels by 2040</a>under intermediate and high greenhouse gas emissions scenarios, bringing with it <a href="https://www.ipcc.ch/sr15/chapter/spm/">higher temperatures on land and in the ocean, declining sea ice, more heat waves, more rainfall in some regions and a greater chance of drought in others</a>. With increasing exposures to these hazards comes greater incidences of negative mental health outcomes. The findings outlined in the report confirm the depth, breadth and significance of the ways climate change impacts mental health. This synthesis of global research indicates that these negative mental health outcomes are on the rise and unequally distributed due to climate change. Here are three things that the latest IPCC report tells us about climate change and mental health in North America. 1. There is greater scientific understanding about the ways that climate change negatively impacts mental health. When the <a href="https://www.ipcc.ch/report/ar5/wg2/">IPCC Fifth Assessment Report</a> (AR5) was published in 2014, there was emerging yet limited research on mental health outcomes. The report mentioned that climate change could affect mental health, but there wasn’t enough published research available then to fully assess its impacts. As the volume of research on <a href="https://doi.org/10.1016/j.envres.2021.111205">climate change and mental health has grown</a>, this new report is now able to assess its impact. Researchers have been able to examine how both climate and weather extremes such as storms, floods, droughts and fires and slower-onset climate changes such as warming temperatures and changing environmental norms interact with people’s vulnerabilities such as socio-economic inequities, age, gender, identity, occupation and health and lead to a diverse range of negative mental health outcomes. For example, a <a href="https://doi.org/10.1371/journal.pone.0119929">synthesis of global literature</a> found that those exposed to flooding events — such as the floods in southern British Columbia in 2021, in Ottawa in 2019 and Alberta in 2013 — experience PTSD, depression and anxiety in the short term and have elevated risks for these mental health outcomes in the long term. Similar mental health outcomes were found for those <a href="https://doi.org/10.17269/s41997-018-0070-5">exposed to wildfires and related smoke</a>, such as the wildfires in the Northwest Territories in 2014, Fort McMurray, Alta., in 2016 and Lytton, B.C., in 2021. Our <a href="https://doi.org/10.1016/j.socscimed.2012.03.043">own work</a> with Inuit in Nunatsiavut, Labrador, demonstrates the ways in which slower, cumulative impacts from rising temperatures, declining sea ice and changing seasonal, animal and plant patterns disrupt land-based activities and livelihoods, <a href="https://doi.org/10.1007/s10584-013-0875-4">leading to negative consequences for mental and emotional well-being</a>. This includes <a href="https://doi.org/10.1016/j.emospa.2011.08.005">strong emotional reactions</a> (stress, anger, fear and distress), <a href="https://doi.org/10.1038/s41558-018-0092-2">ecological grief</a> and loss, expressions of anxiety and depression and <a href="http://www.lamentfortheland.ca/">loss of cultural knowledge and place-based identities and connections</a>. 2. The mental health impacts of climate change are unequally distributed. Climate change works across intersecting social determinants of health — factors such as age or gender that influence health and how people live — to disproportionately affect certain groups. For example, AR6 demonstrates that some people and communities are most at risk for increasingly worsening mental health outcomes, due to their proximity to the hazard, their reliance on the environment for livelihood and culture and their socio-economic status: <ul> <li><a href="https://doi.org/10.1016/j.socscimed.2017.01.009">Agricultural communities</a> already experiencing drought or changing environmental conditions. </li> <li>People living in areas exposed to <a href="https://doi.org/10.17269/s41997-018-0070-5">wildfires</a> and <a href="https://doi.org/10.1371/journal.pone.0119929">floods</a>.</li> <li><a href="https://doi.org/10.1088/1748-9326/ab68a9">Indigenous Peoples</a> and those closely dependent on the natural environment for livelihoods and culture </li> <li><a href="https://changingclimate.ca/health-in-a-changing-climate/">Women, the elderly</a>, <a href="https://dx.doi.org/10.2139/ssrn.3918955">children and young people</a> and those already experiencing <a href="https://www.apa.org/news/press/releases/2017/03/mental-health-climate.pdf">chronic physical and mental health issues</a>.</li> </ul> 3. It’s not too late to promote resilience. Climate change is not a distant threat. It’s a growing reality. Urgent action is needed to protect the mental health of individuals, communities and health systems under rapid climate change and support individual and community resilience and well-being. Resilience can be enhanced through climate-specific mental health outcomes training and policy action, which support health systems to enhance individual and community mental health and well-being. For example, the American Psychological Association outlines strategies to build personal resilience, including building belief in one’s own reslience, fostering optimism, cultivating coping strategies, finding sources of personal meaning, finding social support networks (family, friends, organized groups), fostering and upholding a connection to place and maintaining connections to one’s culture. Incorporating climate-specific training in education and for physicians, nurses, psychologists, psychiatrists, counsellors and allied health professionals, is essential for building climate-literate health professionals capable of supporting individual and community resilience and for preparing health systems to better serve those experiencing climate-sensitive mental health challenges. Finally, <a href="https://changingclimate.ca/health-in-a-changing-climate/chapter/10-0/">health systems and health authorities</a> must take measures to assess and enhance health system readiness to deal with growing mental health needs and increase disaster planning and training, to further support individual and community resilience to climate change. <h2>Moving forward</h2> Based on the available evidence, the mental health impacts from climate change are already widespread and likely to worsen. Even with immediate and strong action towards mitigation and adaptation, climate change will continue to be a serious threat. It is critical that we understand the serious risks that climate change poses to mental well-being and take urgent action to support health systems and enhance individual and community mental health and resilience within a changing climate. Although more evidence is needed to determine the most effective programs and policies to reduce negative mental health outcomes from climate change, the effectiveness of individual and group therapy, place-specific and culturally responsive mental health infrastructure and <a href="https://doi.org/10.1186/s12199-019-0822-8">nature-based therapies</a> have been well-proven in other areas, and show promise. Protecting individual and community mental health and well-being requires action from all levels of government and health authorities and integrating a mental health lens and a “<a href="https://www.cmaj.ca/content/192/3/E61">Health in All Policies</a>” approach. Major <a href="https://changingclimate.ca/health-in-a-changing-climate/chapter/10-0/">co-benefits for health and well-being </a>in general, and mental health in particular, can arise when decision-makers in all sectors consider and promote health and health equity through adaptation strategies, while taking urgent measures to mitigate greenhouse gas emissions and limit global warming to 1.5 C.

Vaginal birth after caesarean increases the risk of serious perineal tear by 20%, our large-scale review shows

Pregnant women who previously birthed by caesarean section are presented with a choice: whether to try for a vaginal birth, or book in for a repeat caesar. Those mulling over a vaginal birth are counselled at length about the risk of a rare but nasty outcome – the uterus rupturing while labour is in full flight. But new research looking at 130,000 births over five years has uncovered an increased risk of another outcome women deserve information about: extensive tearing around the vaginal region during birth. Our new study, <a href="https://pubmed.ncbi.nlm.nih.gov/34913246/">published</a> in the British Journal of Obstetrics and Gynaecology, hones in on the risk of vaginal trauma for those who birth vaginally after a prior caesarean. This kind of birth trauma relates to significant injury to a woman’s perineum, the important region between the vagina and anus. The perineum anchors many pelvic floor muscles that help control the bladder and bowels. We defined serious birth injury as a tear in the perineum that <a href="https://www.thewomens.org.au/images/uploads/fact-sheets/Perineal-tears-third-and-fourth-degree.pdf">extends</a> into the anal sphincter – the delicate ring of muscle that helps us control our bowels. Damage to this muscle is called a third-degree perineal tear. <h2>What we studied</h2> The study looked at 130,000 births in Victoria and compared the risk of a third-degree perinatal tear among first-time mums with those who birth vaginally after a prior caesarean (sometimes referred to as a <a href="https://www.acog.org/womens-health/faqs/vaginal-birth-after-cesarean-delivery">VBAC</a>). In our study, vaginal birth included women birthed without any medical assistance, and births by forceps or the ventouse (vacuum birth). Anything but birth by caesarean. The results were clear: a vaginal birth after a previous caesarean increases the chance of significant vaginal trauma (third-degree tear) by 21% (albeit from a low baseline rate). A potential reason for this increased risk might include a mismatch between a uterus that has birthed before and a perineum that has not. If this is the case, the labour progresses quickly, which does not allow enough time for the perineum to stretch naturally. However, the real reason for this risk is unknown and further research is needed. <h2>Lifelong impacts</h2> Once a vaginal birth injury occurs, the tears are immediately repaired by obstetricians. Many women heal fully – but some who sustain a third-degree tear during birth develop distressing issues that never disappear, despite expert care, including from specialist physiotherapists. Symptoms can include an ongoing dragging sensation in the pelvic floor, or true prolapse of the vaginal walls. Sometimes, coughing or sneezing can cause urine leakage. And for some, jogging becomes too hard due to leaking of urine and pelvic discomfort. Others might suffer from reduced faecal control and even the odd episode of faecal soiling. Sex can be painful. <a href="https://images.theconversation.com/files/442177/original/file-20220124-13-zzb927.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/442177/original/file-20220124-13-zzb927.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" alt="woman with caesar scar holds baby" /></a> Women who had a caesarean birth the first time around are at greater risk of serious birth injury from a subsequent vaginal birth. <a href="https://image.shutterstock.com/image-photo/closeup-woman-belly-scar-cesarean-600w-1883782888.jpg" class="source">Shutterstock</a> <h2>This doesn’t mean women shouldn’t consider VBAC</h2> This increased risk of injury does not make it unsafe for women who have had a caesarean before to try for a vaginal birth. But our results should be incorporated into counselling of these women about their choices. Since the risk of vaginal birth injury including the anal sphincter sits at <a href="https://www.safetyandquality.gov.au/sites/default/files/2021-04/perineal_tears_ccs_v3.pdf">around 5-7%</a> in Victoria for first-time mothers, the increase of 21% raises the overall likelihood to around 6–8.5%. It’s a modest rise that will bother some, but not others. Still, women deserve to be given this information so they can judge for themselves whether it worries them enough to ask for a repeat caesarean, or try for a vaginal birth. <a href="https://images.theconversation.com/files/442432/original/file-20220125-23-f3cuam.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/442432/original/file-20220125-23-f3cuam.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" alt="pregnant woman in waiting room" /></a> Birth counselling should fully explain the risks. <a href="https://www.shutterstock.com/image-photo/pregnant-woman-courses-expectant-mothers-1185645562" class="source">Shutterstock</a> Counselling is not just about cautioning women of the risks. As midwives and obstetricians, we talk with these women about what will happen when they go into labour, when to come into hospital, and what their chance (and definition) of “successful” vaginal birth might be. We also mention the most enticing advantage for those whose destiny is an uncomplicated vaginal birth – they sidestep another caesar. Often, this means a <a href="https://pubmed.ncbi.nlm.nih.gov/17181678/">shorter recovery time</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/23186385/">improved likelihood of breastfeeding</a>. After these discussions, some women will feel the very small risk of serious vaginal trauma (or <a href="https://doi.org/10.1371/journal.pmed.1001184">uterine rupture</a>) is one well worth taking and opt to try for a vaginal birth. Others will opt for the certainty of a repeat caesarean. Women deserve full support in their birth choices. And they deserve to be fully informed about possible risks. It’s time we broaden our discussions with women planning a vaginal birth after caesarean section to include the increased risk of vaginal birth trauma.<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; text-shadow: none !important;" src="https://counter.theconversation.com/content/173249/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/anthea-lindquist-1296574">Anthea Lindquist</a>, Obstetrician and Perinatal Epidemiologist, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> and <a href="https://theconversation.com/profiles/stephen-tong-1310350">Stephen Tong</a>, Professor of Obstetrics and Gynaecology, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Four ways having a pet increases your lifespan

Pet owners will often swear their beloved pooch or moggie does wonders for their wellbeing, and now we have empirical proof. A <a href="https://www.nature.com/articles/s41598-017-16118-6">new study</a> has found dog ownership is linked to improved heart health for humans. This is an important finding, given heart disease is the <a href="http://www.who.int/mediacentre/factsheets/fs310/en/">leading cause of death</a> globally. While the new study focuses on dogs and heart disease, it raises the broader question of how pet ownership affects human longevity. Can pets create health in humans? A study known as the “blue zone” study has focused on factors affecting <a href="http://www.sciencedirect.com/science/article/pii/S0531556504002141">longevity</a> for over a decade. <a href="http://journals.sagepub.com/doi/abs/10.1177/1559827616637066#articleCitation">Nine factors</a> have been identified as increasing lifespan in the communities studied, and many of these factors are increased by pets. <h2>1. Natural everyday movement</h2> Much of the focus on pets providing health has been on dog walking. But anyone who owns a pet knows there are numerous incidental physical activities associated with pet ownership – like getting up to feed their pet; ensuring the pet’s food and water is available; and looking after pet “accommodation”. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5491133/">Reducing prolonged sitting</a> and <a href="https://bmcpublichealth.biomedcentral.com/articles/10.1186/1471-2458-11-762">increasing incidental domestic activity</a> have both been shown to be protective with regard to health risks. Pets provide <a href="https://www.researchgate.net/profile/Marc_Suhrcke/publication/49784905_Judging_Nudging_Can_Nudging_Improve_Population_Health/links/0c96052bcb6a2b31d6000000.pdf">nudges</a> to everyday movement. <a href="https://images.theconversation.com/files/202223/original/file-20180117-53295-isgsvi.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/202223/original/file-20180117-53295-isgsvi.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" alt="" /></a> You must get out of bed so you can feed me. <a href="https://unsplash.com/photos/gAAtlPqweaU" class="source">Unsplash/anthony de kroon</a>, <a href="http://creativecommons.org/licenses/by/4.0/" class="license">CC BY</a> <h2>2. Having a sense of purpose</h2> At the very simplest level, pets can provide “<a href="https://lemosandcrane.co.uk/resources/RISE%20Pet%20ownership%20and%20mental%20illness.pdf">a reason to get up in the morning</a>”. This has been shown to be particularly important for groups at risk of, or experiencing, poorer health – including <a href="https://www.hindawi.com/journals/cggr/2014/623203/">the aged</a>, people with <a href="https://bmcpsychiatry.biomedcentral.com/articles/10.1186/s12888-016-1111-3?utm_campaign=BMC40562B&utm_medium=BMCemail&utm_source=Teradata">long-term mental illness</a> and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3785224/">chronic diseases</a> (including <a href="http://onlinelibrary.wiley.com/doi/10.1111/j.1442-2018.2004.00207.x/full">youth</a>). Our (as-yet-unpublished) research interviewing older people about the impact of their pets on health has found pets could be protective against suicide. Pets are seen as reliant on their owners functionally (“need me to feed them or they will die”) and emotionally (“he would pine for me terribly”). Feeling unneeded and of no use has been identified as a key <a href="http://www.apa.org/science/about/psa/2009/06/sci-brief.aspx">risk factor</a> in suicide. <h2>3. Regular destressing activities</h2> Interaction with pets can reduce stress.

Extreme heat increases health risk for everyone

<div class="copy"> Extreme heat is a <a rel="noreferrer noopener" href="https://cosmosmagazine.com/earth/climate/understanding-killer-heat/" target="_blank">killer</a>. It’s responsible for thousands of deaths around the world every year, with a huge proportion of those already <a rel="noreferrer noopener" href="https://cosmosmagazine.com/earth/climate/climate-change-causes-one-third-of-heat-related-deaths/" target="_blank">attributed to rising global temperatures</a>. Studies have long shown that people over the age of 65 face an increased risk of hospital admission and death during extreme heat days, but US and Canadian researchers have now found that young and middle-aged people are at risk, too. “By looking at emergency department visits for different causes and for several age groups, we were able to characterise with accuracy the varying impact on health on different populations,” says study co-author Francesca Dominici, from the Harvard T.H. Chan School of Public Health. “An important goal of this study is to provide actionable information to clinicians and public health experts regarding how to prevent these emergency department visits, also considering that we can anticipate when these extreme heat events are likely to occur.” Published in the BMJ, <a rel="noreferrer noopener" href="https://dx.doi.org/10.1136/BMJ-2021-065653" target="_blank">the study</a> found that extremely hot days – with an average temperature of 34.4°C – are associated with a higher risk of emergency department (ED) presentation for adults of all ages. The strongest association was for adults between the ages of 18 and 64. The study was large, spanning more than 74 million adults and 22 million ED visits across 2939 US counties during the months of May to September from 2010 to 2019. It used medical insurance claims data to investigate links between hot days and rates of ED visits for any cause as well as specific causes (namely heat-related illness, kidney disease, cardiovascular disease, respiratory disease and mental disorders). Extreme heat days increased people’s risk of an ED visit by 66% for a heat-related illness, as well as by 30% for renal disease. But the risk varied with age – there was a 10.3% higher risk of ED visits in people ages 45 to 54 years old, compared to a 3.6% higher risk in those older than 75. “Younger adults may be at greater risk of exposure to extreme heat, particularly among workers that spend substantial time outdoors,” says lead author Shengzhi Sun, from the Department of Environmental Health at Boston University School of Public Health (BUSPH). “Younger adults may also not realise that they too can be at risk on days of extreme heat.” Gregory Wellenius, professor of environmental health at BUSPH, says the researchers chose to look at ED visits instead of hospital admissions for a reason. “Many illnesses that lead to utilisation of the emergency department do not lead to hospitalisation because they can be treated in a short amount of time, particularly among the younger adult population,” he explains. “By looking at emergency room visits, we aimed to obtain a more comprehensive picture of the true burden of disease that might be attributed to the days of high heat.” The study also found differences in risk across regions – there was a higher risk of ED visits on extreme heat days in the US’s northwest, midwest and northwest, as opposed to the hotter southeast. The researchers say this shows heat is especially dangerous in cooler climates, where people may be less adapted to, or less aware of, heat. This is crucial to recognise as global temperatures rise, particularly as countries, states and regions are deciding how to adapt. “Although climate change is a global problem and heat threatens the health of everybody across the world, the impacts are felt locally, and the solutions have to be tailored to local needs,” says Wellenius. “What works for heatwave preparedness in the Pacific Northwest is really different from what works in the southeastern US, so the solutions have to be localised to accommodate the needs of the local community.” Extreme heat is a particular problem in cities. Exposure to deadly urban heat has <a rel="noreferrer noopener" href="https://cosmosmagazine.com/earth/climate/scorching-cities-deadly-urban-heat-has-tripled/" target="_blank">tripled</a> since the 1980s, and with more than 50% of the world’s population currently living in urban areas, this signals an urgent need to <a rel="noreferrer noopener" href="https://cosmosmagazine.com/cosmos-briefing/cities-of-the-future/" target="_blank">redesign our future cities</a> to keep us healthy as the world warms.

Traffic noise could increase your risk of dementia

The amount of noise a person is exposed to from road and railway traffic could affect their risk of developing dementia, according to international research. A team from Denmark has investigated the connection between long-term residential exposure to road traffic and railway noise and dementia risk among two million adults over the age of 60 living in Denmark between 2004 and 2017. To do this, they estimated the level of road traffic and railway noise at the most and least exposed sides of every residential address in Denmark. Then, they analysed national health registers in search of all cases of all-cause dementia and different types, including Alzheimer’s disease, vascular dementia, and Parkinson’s disease related dementia. After taking other potentially influential factors into account, the team found that an average of 10 years exposure to noise was associated with a higher risk of dementia. They also found that both road and railway noise were associated with a higher risk of Alzheimer’s, with a 27 percent increase for exposure to road traffic noise of 55 decibels and a 24 percent increase for exposure to railway noise of 50 decibels. But, they found that the increased risk of vascular dementia was only associated with road traffic noise. The researchers note that the study is observational and doesn’t include information about how lifestyle habits could have played a part in participants’ risks of developing dementia. They conclude: “If these findings are confirmed in future studies, they might have a large effect on the estimation of the burden of disease and healthcare costs attributed to transportation noise. “Expanding our knowledge of the harmful effects of noise on health is essential for setting priorities and implementing effective policies and public health strategies focused on the prevention and control of diseases, including dementia.” The researchers estimate that as many as 14 percent of the 8,475 cases of dementia in Denmark in 2017 could be attributed to transportation noise exposure. Transportation noise has been previously linked to several other health conditions, including coronary heart disease, obesity, and diabetes. The study was published in the journal <a rel="noopener" href="https://www.bmj.com/content/374/bmj.n1954" target="_blank">The BMJ</a>. Image: Getty Images

Sharp increase in whale shark injuries might be due to boat encounters

Almost one-fifth of the whale sharks in Western Australia’s Ningaloo Reef Marine Park are showing signs of major scarring or fin amputations, with the number of injured animals increasing in recent years. New research has shown that due to the distinctive scar patterns, it’s being strongly suggested that many of the injuries are due to boat collisions. Whale shark scientist Emily Lester from the Australian Institute of Marine Science (AIMS) is horrified by the latest findings. “Some of the major scars were probably bite marks from predators, but most were the marks of blunt trauma, lacerations or amputations arising from encounters with ships, particularly propellers,” Ms Lester said. To make the finding, Lester and colleagues from AIMS and the Department of Biodiversity, Conservation and Attractions (DBCA) reviewed moving and still images of 913 whale sharks taken by Ningaloo tour boat operators between 2008 and 2013. Of these, 146 or 16 per cent of the whale sharks suffered from serious injuries. Due to the whale sharks migration patterns, it is difficult to tell where the injuries happened as whale sharks migrate thousands of kilometres beyond the boundaries of the marine park. “Mitigating the impact of scarring from vessel collisions is challenging, particularly outside of our jurisdiction of State waters,” said DBCA research scientist and co-author Dr Holly Raudino. <blockquote style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" class="instagram-media" data-instgrm-captioned="" data-instgrm-permalink="https://www.instagram.com/p/B63AFyvB-GV/?utm_source=ig_embed&utm_campaign=loading" data-instgrm-version="12"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"></div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"></div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"></div> </div> </div> <div style="padding: 19% 0;"></div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"></div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <a style="color: #000; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none; word-wrap: break-word;" rel="noopener" href="https://www.instagram.com/p/B63AFyvB-GV/?utm_source=ig_embed&utm_campaign=loading" target="_blank">Whaleshark hanging out at Ningaloo Reef😁🐋🦈 .

The data is unable to reveal the amount of fatal ship collisions as the whale shark is “negatively buoyant”, which means that when they die, they sink to the ocean floor. “A collision between a large ocean-going vessel and a whale shark wouldn’t be felt by the ship, as a result, it’s likely that we’re underestimating the number of mortalities from ship strike, since our study could only document sharks that survived their injuries,” Ms Lester said.

Why your risks of breast cancer increase as the oceans rise

It is encouraging to see greater attention in the media to the issue of climate change and its effects on the life-support systems of the planet. The link between breast cancer and the environment, however, is being overlooked. Premenopausal women exposed to high levels of air pollution have a 30 per cent increased risk for breast cancer, according to <a href="https://journals.lww.com/environepidem/Fulltext/2018/09000/Residential_exposure_to_fine_particulate_matter.2.aspx">a paper in Environmental Epidemiology</a> published by Paul Villeneuve, a professor of occupational and environmental health at Carleton University, and his research team last year. This should trigger a wake-up call given that we tend to think of breast cancer as a disease of aging women. In fact, the science of breast cancer tells us that “<a href="https://www.tandfonline.com/doi/abs/10.1179/107735209799449761">genetic susceptibility makes only a small to moderate contribution</a>” to breast cancer. The known risk factors — such as family history, age, gender, ethnicity and hormones — account for <a href="https://www.ncbi.nlm.nih.gov/pubmed/22129067">only around three in 10 cases</a>. The other 70 per cent are likely related mostly to environment — including the air, water and soil, the places we live and work in and the products we consume — according to current research. In Canada, <a href="http://www.cancer.ca/en/cancer-information/cancer-type/breast/statistics/?region=on">over 26,300 women were diagnosed with breast cancer in 2017</a> so that 70 per cent represents a lot of women. Carcinogens in the workplace <a href="https://doi.org/10.1186/1476-069X-11-87">Our work environments</a> are part of this story. A paper published last November in New Solutions Journal <a href="https://doi.org/10.1177/1048291118810900">points to workplace exposures as the cause for one woman’s breast cancer</a>. Using the evidence presented at a worker’s compensation hearing, Michael Gilbertson, a former federal government biologist who studied the health effects of toxic chemicals, and Jim Brophy, an occupational health researcher, found that they could infer a causal relationship between the woman’s diagnosis of breast cancer and her high exposure to air pollution — as a border guard at the bridge connecting Windsor, Ont. to Detroit, Mich. Despite the scientific evidence highlighting environmental factors and the important role they likely play in contributing to breast cancer, the woman at the bridge was denied compensation. She was denied even though breast cancers were occurring in this region at a rate up to 16 times higher than the rest of the county, and in an environment with <a href="https://doi.org/10.1002/cncr.22653">pollutants containing known breast carcinogens</a> such as benzene and polycyclic aromatic hydrocarbons. It is not surprising, given that environment is regularly ignored when we talk about breast cancer. A disease of our communities When researchers study what women know about breast cancer they find a focus on cures, detection and treatments. What’s often missing from their list is prevention, and <a href="https://doi.org/10.1080/10410236.2010.496836">prevention is often confused with early detection</a>. Primary prevention means stopping cancer before it starts — not finding it and treating it early, although that too is important. Women’s knowledge of breast cancer is importantly <a href="https://doi.org/10.1111/1467-9566.00274">connected to media and medical practitioner’s messages</a>. Forecasts of the future of cancer tell us that <a href="https://www.canada.ca/en/public-health/services/chronic-diseases/cancer/canadian-cancer-statistics.html">one in two Canadians</a> will likely be diagnosed with cancer in their lifetime. Projections show rising rates of many cancers, including breast cancer. Dr. Ted Schettler, who wrote <a href="https://www.healthandenvironment.org/docs/EcologyOfBreastCancer_Schettler.pdf">The Ecology of Breast Cancer</a> argues: <blockquote> “breast cancer is not only a disease of abnormal cells, but also of communities we create and live in.” </blockquote> If we apply his argument, it means we can create conditions for fewer future breast cancers. The question then becomes how? We cannot blame women To start, we need to make prevention at least as much a priority as early detection, better treatments and the search for cures. We also have to take a good look at all suspected causes. Conversations about prevention often stir debate about what is to blame for the breast cancer rates we are seeing. But an aging population of women who make bad lifestyle choices doesn’t explain increases in breast cancers in more and younger women. It doesn’t explain why women who migrate from countries with lower rates of breast cancer develop the same rates within 10 years of living in their new homes. It also doesn’t explain the clusters of breast cancers in regions with high levels of air pollution containing definitive breast carcinogens. We need confidence in what the science is already showing us about the role of <a href="https://ehjournal.biomedcentral.com/articles/10.1186/s12940-017-0287-4#Sec49">environmental and workplace hazards</a> in breast cancer causation. Indeed, the evidence points to <a href="https://www.eurekalert.org/pub_releases/2017-10/ssi-ete101017.php">associations between numerous environmental pollutants</a> and an increased risk for breast cancer — <a href="https://www.ncbi.nlm.nih.gov/pubmed/17503434">including pesticides, herbicides, synthetic chemicals, endocrine disrupting chemicals and vehicle emissions</a>. <a href="https://journals.lww.com/joem/Abstract/2011/05000/Breast_Cancer_Risk_Associated_With_Residential.10.aspx">Living and working in proximity to these exposures</a>, especially during vulnerable windows of development, is <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1240618/">putting women</a> at <a href="https://www.ncbi.nlm.nih.gov/pubmed/22129067">high risk</a>. <a href="https://doi.org/10.1186/1476-069X-11-87">Some occupations</a>, including radiology, pharmacy, health care, hairdressing, working with plastics, manufacturing, agriculture, working as airline crew and firefighting, also <a href="https://doi.org/10.1177/1048291118758460">carry a higher risk</a>. These <a href="https://d124kohvtzl951.cloudfront.net/wp-content/uploads/2017/03/02025357/Report_Working-Women-and-Breast-Cancer_August_2015.pdf">occupational sectors employ thousands of thousands of women</a> worldwide. We need greater awareness and extended programmes that focus on these environmental and workplace causes. And we need to create and enforce policies and put regulations in place that prevent such exposures. The climate change link The women in Paul Villeneuve’s study are not unlike the female border guard. These cases are all linked to high levels of air pollution. Their stories are those of countless other women who face exposures to breast carcinogens in many Canadian urban environments and workplaces with high levels of traffic and industrial pollution. We also have evidence that these exposures are increasing, as our climate is changing. This link is complex, as is so much about cancer generally. Air pollution is <a href="https://www.who.int/sustainable-development/AirPollution_Climate_Health_Factsheet.pdf">one of the many causes of climate change</a> as well as <a href="https://journals.lww.com/environepidem/Fulltext/2018/09000/Residential_exposure_to_fine_particulate_matter.2.aspx">breast cancer</a>. It is also believed that increased ambient air temperatures may change the effects of chemical contaminants on humans and that increased precipitation and flooding will <a href="https://setac.onlinelibrary.wiley.com/doi/full/10.1002/etc.2046">move contaminants to places where greater exposure by humans is possible</a>. Finally, as the incidence of fires increase with climate change, exposures to chemicals associated with the development of breast cancer often found in fires also increase. Studies are now investigating <a href="http://womenfirefighterstudy.com/about/">possible elevated incidence of breast cancer among women firefighters</a>. They are clearly a highly exposed group and may be just one example of women bearing an elevated breast cancer risk. Prevention a priority At this important moment in history, as we debate the poor state of the environment and the adverse outcomes associated with it, we have the opportunity to make prevention of the many diseases — including breast cancer — a priority. Many stories report on the numerous health problems connected to climate change including other cancers, cardiovascular disease, fertility problems, asthma, adverse birth outcomes, disabilities, diabetes and stroke. And yet, despite increasing evidence of an association between breast cancer and environmental exposures, the media does not cover this piece of the story. We must do the work now to create a future where we won’t have to surrender our good health to unregulated exposure to known and suspected breast carcinogens. Instead we must <a href="https://deainfo.nci.nih.gov/ADVISORY/pcp/annualReports/pcp08-09rpt/PCP_Report_08-09_508.pdf">implement the precautionary principle</a> — in our communities, our workplaces and across our planet.<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; text-shadow: none !important;" src="https://counter.theconversation.com/content/108420/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/jane-e-mcarthur-613732">Jane E.

How to increase the curb appeal of your home in a weekend

Whether your goal is to add value to your home to sell, or you’re just looking to get your home entertainment-ready for summer, there are three DIY projects you can complete in a weekend that will greatly increase the curb appeal of your home. 1. Repaint concrete exteriors Painting an unsightly or worn concrete pathway, landing or wall is one of the most dramatic (and easy) home improvements you can make. With a little prep and some specialty concrete paint you can avoid the pricey task of having to replace the concrete and have it looking like new again. Remember <ul> <li>PREPARATION IS KEY. Remove any lose concrete with a scraper, wire brush or sandpaper then scrub the surface clean with a strong detergent and stiff bristle broom and hose off with clean water. This will stop your paint from lifting and ensure long lasting results. Don’t skip this step!  </li> <li>ROUGHT IT UP. In order for your surface to really grip the paint, you need to make sure the surface is rough (it should feel like 180 grit sandpaper). If the surface is smooth, prep with White Knight Ultra Pave Concrete Etcher. If your surface is already fairly rough you can skip this step.  </li> <li>TIME TO PAINT. Using a roller and tray, first start on the large areas. Using White Knight Ultra Pave Quick Dry, start by painting the far corner and then work backwards so you don’t paint yourself into a corner. If you didn’t use a concrete etcher, I recommend thinning the first coat of paint with 20% water to help with adhesion. Your concrete area will be touch-dry in 30 minutes and ready to be recoated in two hours.</li> </ul> 2. Paint the front door Painting your front door and even your shutters is another easy way to improve the exterior of your home and help to leave a lasting impression. Remember <ul> <li>KNOW YOUR ENVIRONMENT. Select a hardwearing concrete paint such as Ultra Pave which is designed to withstand Australia’s harsh climate.  </li> <li>DARE TO BE DIFFERENT. Remember, paint isn’t permanent so have fun with it. Try a strong contrast colour for maximum visual impact. Think red against a white frame and brick wall, bright yellow against navy, or deep blue on white.  </li> </ul> 3. Landscape Last but certainly not least, a little bit of landscaping can do wonders to improve the curb appeal of your home. Remember <ul> <li>ADD SOME COLOUR A vibrant flower bed can lift the feel of any home.</li> </ul> This is a guest post by Dale Vine, former Block contestant and <a href="http://www.whiteknightpaints.com.au/">White Knight </a>Ambassador.
