5 items you’re cleaning too much

<p>Cleaning the house is no easy feat. To make life a little easier for you, here are five items you are probably cleaning more than you need to. </p> <p><strong>1. Clothes worn once</strong></p> <p>For particular items of clothing such as gym gear, shirts and tights it is fine to wash clothes after every wear. However, most other items can be worn up to three times advises Carolyn Forte, the director of the Cleaning Lab at the Good Housekeeping Institute.</p> <p>"Over-washing and over-drying fabrics can cause fading and wear,” she said. Studies have also shown that it is ideal to wash bath towels after three uses.</p> <p><strong>2. Dinner plates</strong></p> <p>Instead of spending time rinsing your plates before putting them in the dishwasher, just make sure all the food is scrapped off. "Pre-washing dishes is a waste of time and energy,” said Carolyn. "If you aren't running it right away, let the dishwasher rinse them with a 'rinse only' cycle."</p> <p><strong>3. Light Fixtures</strong></p> <p>It can be tempting to dust your light fixtures every week but Carolyn advises saving your strength from a different household task. She advises that you can get away with cleaning light fixtures once a month.</p> <p><strong>4. Jackets</strong></p> <p>In the cooler months jackets are worn every day. However, this necessity only needs to be washed every three months. Jackets don’t usually come into contact with skin cells or natural oils, which allows them to go longer between washes than other clothes.</p> <p><strong>5. Curtains</strong></p> <p>Curtains need to be washed if you get any marks on them but if they are in pristine condition, according to Carolyn they only need to be cleaned once a year.</p> <p><em>Image credits: Shutterstock </em></p>

"Not much of me left": Elton John's grim health confession

<p>Elton John has made a blunt admission about his health battles. </p> <p>The 77-year-old singer opened up about his many health issues in a speech at the screening of his new documentary<em> Elton John: Never Too Late</em>, at the New York Film Festival on Tuesday. </p> <p>“To be honest with you, there’s not much of me left,” Elton told the audience. </p> <p>“I don’t have tonsils, adenoids or an appendix,” he continued, according to <a href="https://people.com/elton-john-jokes-not-much-of-me-left-listing-missing-organs-documentary-premiere-8721741" target="_blank" rel="noopener"><em>People</em></a> magazine. </p> <p>“I don’t have a prostate. I don’t have a right hip or a left knee or a right knee. In fact, the only thing left to me is my left hip.</p> <p>“But I’m still here,” Elton continued. “And I can’t thank you [enough], you’re the people that made me.”</p> <p>The documentary is directed by his husband David Furnish, and American filmmaker R.J. Cutler.</p> <p>Throughout the years Elton has struggled with his health, and just last month he revealed he was recovering from a "severe eye infection" that affected his vision. </p> <p>This occured after he underwent knee and hip replacement surgery. </p> <p>The<em> I'm Still Standing </em>singer also got a pacemaker fitted in back in the 90s, and was hospitalised for influenza and a bacterial infection in 2009. </p> <p>In 2013 he had an abscess on his appendix, and three years later he had suffered from "gastric flu". </p> <p>In addition to all of these health woes he has dealt with hearing loss caused by years of touring. </p> <p>The singer also talked about his retirement from touring at the premiere of his new documentary, following a successful five years of performances and more than 300 shows worldwide. </p> <p>“As you know, I decided to stop touring because I’m 77 years of age,” he said.</p> <p>“I’ve done all there is to do, to play. I’ve succeeded. I’ve been there and I’ve done it.”</p> <p>The documentary explores his 50-year career leading up to his final North American show at Dodger Stadium in 2022. It is set to stream on Disney+ in the US on December 13. </p> <p><em>ADAM VAUGHAN/EPA-EFE/ Shutterstock Editorial</em></p> <p> </p>

Revealed: How much regular sex each generation is having

<p>While it's often seen as a taboo subject, researchers from Kinsey Institute at Indiana University, have just revealed their report on the sex lives of thousands of people around the world and across different generations. </p> <p>The report, titled<em> The State of Dating: How Gen Z is Redefining Sexuality and Relationships</em> is based on data from over 3,310 people of the dating app, Feeld.</p> <p>The participants, who came from 71 different countries and  between 18-75 years old, were surveyed about their sex lives and results are not what you'd expect. </p> <p>Gen Z is having less sex, fewer partners and fewer relationships than other generations, reporting that on average they had had sex three times in the last month. </p> <p>"Gen Z and Boomers exhibited nearly identical sexual frequencies, suggesting that both the youngest and oldest adults are having the least sex," the researchers, led by Dr Justin Lehmiller, wrote in the report.</p> <p>Millennials and Gen X reported slightly higher figures, with both groups having sex five times in the last month. </p> <p>"Also, nearly half of Gen Z reported that they were single, compared to only one-fifth of Millennials, Gen X, and Boomers." </p> <p>Despite having the least sex, Gen Z appears to be the most adventurous group in the bedroom, with 55 per cent of them saying they'd discovered a new kink since joining the app compared to 49 per cent of Millennials, 39 per cent of Gen X, and 33 per cent of Boomers.</p> <p>Researchers said there are two possible explanations for this. </p> <p>"One is simply that older adults have had more time to learn and discover what they enjoy about sex, so they may have already uncovered their kinks.</p> <p>"However, the other is that it also appears to be the case that younger adults today have a greater overall interest in kink than older adults, which may create greater openness to exploring and learning about one's kinks."</p> <p>The researchers hope that their findings will help shed new light on the evolution of sex, gender, sexuality and relationships. </p> <p>"Despite the longstanding tendency of humans to narrowly categorize sexuality and relationships, they have always existed on a continuum, and that continuum will only evolve and expand further as Gen Z and future generations continue their pursuit of sexual and relational self-discovery," they wrote. </p> <p>"The more that we can understand and embrace this simple fact of human life, the better suited we will all be to pursuing pleasure and happiness." </p> <p><em>Images: Shutterstock</em></p> <p> </p>

From maxing out to slowing down, how much do heart rates vary across sports?

Fighting for change: how much cash Olympic medallists actually win at Paris 2024

<p>As the world soaks up the glitz and glamour of Paris 2024, athletes are not just eyeing the podium – they're also thinking about the cash they might pocket. Or, in some cases, the cash they might not pocket. Because while the Olympics is a billion-dollar spectacle, the earnings for athletes can range from princely sums to pocket change.</p> <p><strong>Australia: A Gold Medal and a Discount Coupon</strong></p> <p>Let’s start with the Aussies. Winning gold at the Olympics might be the pinnacle of an athlete's career, but for Australian athletes, it also means... $20,000. Yes, you heard that right. In a land where a house deposit will likely cost you a LOT more, Aussie Olympians are basically getting paid in Monopoly money. Silver and bronze medalists get $15,000 and $10,000 respectively. That's enough for a decent holiday, but you might still need a GoFundMe for the flights.</p> <p><strong>Singapore: the million-dollar carrot</strong></p> <p>On the other end of the spectrum, athletes from Singapore are practically diving into pools of gold – like Scrooge McDuck, but in real life. A gold medal will earn them a staggering AU$1.13 million. That’s the kind of money that makes you forget about the gruelling four-year training cycle and instead think about which colour Lamborghini matches your national flag.</p> <p><strong>Hong Kong: fencing your way to riches</strong></p> <p>Hong Kong, not to be outdone, will reward its fencing champion Vivian Kong with AU$1.17 million for her gold. That’s enough to make you consider taking up fencing, even if you’re as coordinated as a baby giraffe.</p> <p><strong>Malaysia and Kazakhstan: cars and apartments</strong></p> <p>In Malaysia, winning athletes might not get cold hard cash, but they do get a new car. And in Kazakhstan, you can literally earn a place to call home – with more rooms depending on the colour of your medal. A gold gets you a penthouse, a silver a two-bedroom, and a bronze... well, maybe a studio with a view of the parking lot.</p> <p><strong>France: host with the most (ish)</strong></p> <p>The host nation, France, offers a more modest reward of $108,000 for a gold medal. That’s enough to cover a year's rent in Paris, or a really good wine collection. But let’s face it, in the land of fine dining, they might just spend it all on cheese.</p> <p><strong>New Zealand, Norway and the UK: the love of the game</strong></p> <p>Athletes from New Zealand, Norway and the UK? Well, they’ll have to make do with a pat on the back and a hearty “well done”, because there’s no financial incentive for winning a medal in these countries. Just the satisfaction of representing your nation, which, as any athlete will tell you, doesn't pay the bills.</p> <p><strong>The United States: the great divide</strong></p> <p>The US offers $37,500 for a gold medal, but that's chump change compared to the endorsement deals top athletes like swimmer Katie Ledecky pull in. She's reportedly earning $1 million a year from swimwear endorsements. Meanwhile, many other American athletes are scraping by, with some earning less than $15,000 a year. That's barely enough for a year's supply of Weet-Bix, let alone world-class training.</p> <p><strong>Jamaica: sharing the love</strong></p> <p>Jamaica’s Olympic team will share a pot of about AU$3,500 each, regardless of their results. It's the ultimate participation trophy – except it’s not enough to buy a trophy, or even a decent pair of running shoes.</p> <p><strong>World Athletics: the global jackpot</strong></p> <p>World Athletics is offering a $3.6 million prize pool for track and field events, with $76,000 per gold medalist. It's a model that some athletes, like Australia’s Arianne Titmus, think other sports should follow. After all, nothing says “thank you for your hard work” like a big, fat cheque.</p> <p>So, whether they’re racing for millions or just a modest thank you, athletes at Paris 2024 will be giving it their all. Because at the end of the day, it's not just about the money. It's about the glory, the honour, and ... well, okay, it’s mostly about the money.</p> <p><em>Images: Instagram \ Shutterstock</em></p>

3 signs your diet is causing too much muscle loss – and what to do about it

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/nick-fuller-219993">Nick Fuller</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>When trying to lose weight, it’s natural to want to see quick results. So when the number on the scales drops rapidly, it seems like we’re on the right track.</p> <p>But as with many things related to weight loss, there’s a flip side: rapid weight loss can result in a significant loss of muscle mass, as well as fat.</p> <p>So how you can tell if you’re losing too much muscle and what can you do to prevent it?</p> <h2>Why does muscle mass matter?</h2> <p>Muscle is an important factor in determining our metabolic rate: how much energy we burn at rest. This is determined by how much muscle and fat we have. Muscle is more metabolically active than fat, meaning it burns more calories.</p> <p>When we diet to lose weight, we create a calorie deficit, where our bodies don’t get enough energy from the food we eat to meet our energy needs. Our bodies start breaking down our fat and muscle tissue for fuel.</p> <p>A decrease in calorie-burning muscle mass slows our metabolism. This quickly slows the rate at which we lose weight and impacts our ability to maintain our weight long term.</p> <h2>How to tell you’re losing too much muscle</h2> <p>Unfortunately, measuring changes in muscle mass is not easy.</p> <p>The most accurate tool is an enhanced form of X-ray called a dual-energy X-ray absorptiometry (DXA) scan. The scan is primarily used in medicine and research to capture data on weight, body fat, muscle mass and bone density.</p> <p>But while DEXA is becoming more readily available at weight-loss clinics and gyms, it’s not cheap.</p> <p>There are also many “smart” scales available for at home use that promise to provide an accurate reading of muscle mass percentage.</p> <p>However, the accuracy of these scales is questionable. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8122302/">Researchers found</a> the scales tested massively over- or under-estimated fat and muscle mass.</p> <p>Fortunately, there are three free but scientifically backed signs you may be losing too much muscle mass when you’re dieting.</p> <h2>1. You’re losing much more weight than expected each week</h2> <p>Losing a lot of weight rapidly is one of the early signs that your diet is too extreme and you’re losing too much muscle.</p> <p>Rapid weight loss (of more than 1 kilogram per week) results in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5702468/">greater muscle mass loss</a> than slow weight loss.</p> <p>Slow weight loss better preserves muscle mass and often has the added benefit of <a href="https://www.sciencedirect.com/science/article/pii/S0195666312000153">greater fat mass loss</a>.</p> <p>One study compared people in the obese weight category who followed either a very low-calorie diet (500 calories per day) for five weeks or a low-calorie diet (1,250 calories per day) for 12 weeks. While both groups lost similar amounts of weight, participants following the very low-calorie diet (500 calories per day) for five weeks lost <a href="https://pubmed.ncbi.nlm.nih.gov/26813524/">significantly more muscle mass</a>.</p> <h2>2. You’re feeling tired and things feel more difficult</h2> <p>It sounds obvious, but feeling tired, sluggish and finding it hard to complete physical activities, such as working out or doing jobs around the house, is another strong signal you’re losing muscle.</p> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3648712/">Research</a> shows a decrease in muscle mass may negatively impact your body’s physical performance.</p> <h2>3. You’re feeling moody</h2> <p>Mood swings and feeling anxious, stressed or depressed may also be signs you’re losing muscle mass.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/26228522/">Research</a> on muscle loss due to ageing suggests low levels of muscle mass can negatively impact mental health and mood. This seems to stem from the relationship between low muscle mass and proteins called neurotrophins, which help regulate mood and feelings of wellbeing.</p> <h2>So how you can do to maintain muscle during weight loss?</h2> <p>Fortunately, there are also three actions you can take to maintain muscle mass when you’re following a calorie-restricted diet to lose weight.</p> <h2>1. Incorporate strength training into your exercise plan</h2> <p>While a broad exercise program is important to support overall weight loss, strength-building exercises are a surefire way to help prevent the loss of muscle mass. A <a href="https://pubmed.ncbi.nlm.nih.gov/29596307/">meta-analysis of studies</a> of older people with obesity found resistance training was able to prevent almost 100% of muscle loss from calorie restriction.</p> <p>Relying on diet alone to lose weight will reduce muscle along with body fat, slowing your metabolism. So it’s essential to make sure you’ve incorporated sufficient and appropriate exercise into your weight-loss plan to hold onto your muscle mass stores.</p> <p>But you don’t need to hit the gym. Exercises using body weight – such as push-ups, pull-ups, planks and air squats – are just as effective as lifting weights and using strength-building equipment.</p> <p>Encouragingly, moderate-volume resistance training (three sets of ten repetitions for eight exercises) <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/sms.14237">can be as effective</a> as high-volume training (five sets of ten repetitions for eight exercises) for maintaining muscle when you’re following a calorie-restricted diet.</p> <h2>2. Eat more protein</h2> <p>Foods high in protein play an essential role in building and maintaining muscle mass, but <a href="https://europepmc.org/article/MED/19927027">research</a> also shows these foods help prevent muscle loss when you’re following a calorie-restricted diet.</p> <p>But this doesn’t mean <em>just</em> eating foods with protein. Meals need to be balanced and include a source of protein, wholegrain carb and healthy fat to meet our dietary needs. For example, eggs on wholegrain toast with avocado.</p> <h2>3. Slow your weight loss plan down</h2> <p>When we change our diet to lose weight, we take our body out of its comfort zone and trigger its survival response.

How much do you need to know about how your spouse spends money? Maybe less than you think

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/scott-rick-1534612">Scott Rick</a>, <a href="https://theconversation.com/institutions/university-of-michigan-1290">University of Michigan</a></em></p> <p>Love is in the air, and wedding season is upon us.</p> <p>Like many elder millennials, I grew up watching sitcoms in the 1980s and ‘90s. Whenever those series needed a ratings boost, they would feature a wedding. Those special episodes taught me that weddings usually involve young lovebirds: think Elvin and Sondra from “The Cosby Show,” Cory and Topanga from “Boy Meets World,” or David and Darlene from “Roseanne.”</p> <p>But those were different times. People are getting married later in life than they used to: In the United States, <a href="https://www.census.gov/content/dam/Census/library/visualizations/time-series/demo/families-and-households/ms-2.pdf">the median age of newlyweds</a> has grown to 28 for women and 30 for men.</p> <p>This trend means that many Americans now enter marriage after being self-reliant for several years, including managing their own money. Will they be eager to change that once they get married? Don’t count on it. A 2017 <a href="https://bettermoneyhabits.bankofamerica.com/content/dam/bmh/pdf/ar6vnln9-boa-bmh-millennial-report-winter-2018-final2.pdf">Bank of America survey</a> suggests that millennial married couples are around 15 percentage points more likely than their predecessors to keep their finances separate.</p> <p>This is not necessarily a good development. As a behavioral scientist <a href="https://michiganross.umich.edu/faculty-research/faculty/scott-rick">who studies money and relationships</a>, I find that joint accounts <a href="https://doi.org/10.1093/jcr/ucad020">can bring partners closer</a>.</p> <p>There are some risks, however. Joint accounts create transparency, and intuitively, transparency feels like a good thing in relationships. But I argue that some privacy is important even for highly committed couples – <a href="https://us.macmillan.com/books/9781250280077/tightwadsandspendthrifts">and money is no exception</a>.</p> <h2>The newlywed game</h2> <p>Behavioral scientists <a href="https://kelley.iu.edu/faculty-research/faculty-directory/profile.html?id=jgolson">Jenny Olson</a>, <a href="https://som.yale.edu/faculty-research/faculty-directory/deborah-small">Deb Small</a>, <a href="https://www.kellogg.northwestern.edu/faculty/directory/finkel_eli.aspx">Eli Finkel</a> and I recently conducted <a href="https://academic.oup.com/jcr/article-abstract/50/4/704/7077142">an experiment with engaged and newlywed couples</a>. Each of the pairs had entirely separate accounts, but they were undecided about how they wanted to manage their money moving forward.</p> <p>We randomly assigned each of the 230 couples to one of three groups. One group kept their money in separate accounts; one merged their cash into a joint account and stopped using separate accounts; and one managed their money however they liked.</p> <p>We followed couples for two years, periodically asking them to complete surveys assessing their relationship dynamics and satisfaction. Our relationship quality measure included items such as “I cannot imagine another person making me as happy as my partner does” and “Within the last three months, I shouted or yelled at my partner.”</p> <p>Among the couples who could do whatever they wanted, most kept things separate. They and the couples assigned to keep separate accounts experienced a steady decline in relationship quality over time.</p> <p>This is a fairly typical pattern. For instance, in <a href="https://academic.oup.com/sf/article-abstract/79/4/1313/2234046">a large study that tracked U.S. couples’ marital happiness for 17 years</a>, <a href="https://www.unk.edu/academics/social-work/faculty_staff/van_laningham.php">sociologist Jody Van Laningham</a> and colleagues found that “marital happiness either declines continuously or flattens after a long period of decline.”</p> <p>Declines during the first two years of marriage are particularly important. Social scientist <a href="https://liberalarts.utexas.edu/prc/faculty/hustontl">Ted Huston</a> and colleagues call those first two years <a href="https://doi.org/10.1037/0022-3514.80.2.237">the “connubial crucible</a>.” They find that relationship dynamics that develop during that crucial period can foreshadow relationship quality for many years to come.</p> <p>Couples in our study who were prompted to take the plunge into a joint account, however, maintained their initial level of relationship satisfaction over the course of the two-year experiment.</p> <h2>Tit-for-tat</h2> <p>Our survey results suggest that, by turning “my money” and “your money” into “our money,” a joint account can help to reduce scorekeeping within a relationship. For example, we found that couples with joint accounts were more likely to agree with statements such as “When one person does something for the other, the other should not owe the giver anything.”</p> <p>Relationships usually don’t start with a scorekeeping orientation. In the 1980s and ‘90s, psychologist <a href="https://psychology.yale.edu/people/margaret-clark">Margaret Clark</a> and colleagues conducted experiments where partners had the option of keeping track of each other’s contributions to a shared task. <a href="https://clarkrelationshiplab.yale.edu/sites/default/files/files/Resource%20allocation%20in%20intimate%20relationships.pdf">They observed</a> that intimate relationships often begin with a “communal” orientation, where partners help one another without keeping careful track of who’s doing what.</p> <p>Eventually, however, they take on more of an “exchange” orientation – where inputs are tracked and timely reciprocity is expected. Couples that manage to stave off a tit-for-tat mindset <a href="https://doi.org/10.1177/0956797610373882">tend to be happier</a>.</p> <h2>Too much of a good thing?</h2> <p>The data from our experiment with young couples clearly suggests that using only a joint account is better than using only separate accounts. However, I argue in my new book, “<a href="https://us.macmillan.com/books/9781250280077/">Tightwads and Spendthrifts</a>,” that just a joint account is probably not optimal.</p> <p>When partners use only a joint account, they get an up-close-and-personal view of how the other person is spending money. This kind of transparency is <a href="https://www.businessinsider.com/money-habits-successful-married-couples-avoid-2016-11">normally viewed</a> as a good thing.</p> <p>Some commentators argue that a healthy marriage should have no secrets whatsoever. For example, Willard Harley, Jr., a clinical psychologist who primarily writes for Christian audiences, argues that you should “reveal to your spouse <a href="https://www.marriagebuilders.com/the-policy-of-radical-honesty.htm">as much information about yourself as you know</a>: your thoughts, feelings, habits, likes, dislikes, personal history, daily activities, and plans for the future.”</p> <p>In addition, if your goal is to minimize optional spending, <a href="https://doi.org/10.1002/jcpy.1083">research suggests</a> that the transparency that comes with a joint account can be helpful. We spend less when someone is looking over our shoulder.</p> <p>Still, there are reasons to believe that <a href="https://doi.org/10.1177/0265407500172005">complete transparency can be harmful for couples</a>.</p> <p>Many people have become convinced that if they could just stop buying lattes and avocado toast, they could invest that money and become rich. Unfortunately, the underlying math is highly dubious, as journalist Helaine Olen points out in <a href="https://www.penguinrandomhouse.com/books/308568/pound-foolish-by-helaine-olen/">her book “Pound Foolish</a>.” Still, many people view small indulgences as their primary obstacle to wealth. Complete transparency around these financially inconsequential “treats” <a href="https://slate.com/business/2021/09/partner-hates-retail-therapy-money-advice.html">can lead to unnecessary arguments</a>.</p> <p>Also, spouses may have different passions that their partner does not fully understand. Expenses that seem perfectly reasonable to another hobbyist may seem outrageous <a href="https://academic.oup.com/jcr/article-abstract/19/2/256/1929895">to someone without the proper context</a> – another source of <a href="https://www.sciencedirect.com/science/article/abs/pii/S2352250X21000750">avoidable disagreements</a>.</p> <h2>'Translucent,’ not transparent</h2> <p>I propose that many couples may benefit from a combination of joint and separate accounts.</p> <p>A joint account is essential for ensuring that both partners have immediate and equal access to “our money.” Ideally, all income would be direct-deposited into the joint account, which would help to blur the gap between partners’ earnings. Conspicuous income differences <a href="https://doi.org/10.1086/432228">can jeopardize relationship quality</a>.</p> <p>Separate accounts attached to the joint account can allow some privacy for individual purchases and help partners maintain a sense of autonomy and individuality. Each person gets to spend some of “our money” without their partner looking over their shoulder. Spouses would have a high-level understanding of how much their partner is spending per week or per month, but avoid the occasionally irritating details.</p> <p>This kind of partial financial transparency – <a href="https://us.macmillan.com/books/9781250280077/tightwadsandspendthrifts">what I call “financial translucency</a>” – could help couples strike the right balance between financial and psychological well-being.</p> <p>Of course, this approach requires a lot of trust. If the relationship is already on thin ice, complete financial transparency may be necessary. However, if the relationship is generally in the “good, but could be even better” category, I would argue that financial translucency is worth considering.<!-- Below is The Conversation's page counter tag.

Spending too much time on social media and doomscrolling? The problem might be FOMO

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/kim-m-caudwell-1258935">Kim M Caudwell</a>, <a href="https://theconversation.com/institutions/charles-darwin-university-1066">Charles Darwin University</a></em></p> <p>For as long as we have used the internet to <a href="https://www.theguardian.com/technology/2016/mar/07/email-ray-tomlinson-history">communicate and connect with each other</a>, it has influenced how we think, feel and behave.</p> <p>During the COVID pandemic, many of us were <a href="https://www.sciencedirect.com/science/article/pii/S0277953622007985">“cut off” from our social worlds</a> through restrictions, lockdowns and mandates. Understandably, many of us tried to <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0258344">find ways to connect online</a>.</p> <p>Now, as pandemic restrictions have lifted, some of the ways we use the internet have become concerning. Part of what drives problematic internet use may be something most of us are familiar with – the fear of missing out, or FOMO.</p> <p>In <a href="https://link.springer.com/article/10.1186/s12888-024-05834-9">our latest research</a>, my colleagues and I investigated the role FOMO plays in two kinds of internet use: problematic social media use and “doomscrolling”.</p> <h2>What are FOMO, problematic social media use and doomscrolling?</h2> <p>FOMO is the fear some of us experience when we get a sense of “missing out” on things happening in our social scene. Psychology researchers have been studying FOMO for <a href="https://doi.org/10.1016/j.chb.2013.02.014">more than a decade</a>, and it has consistently been linked to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8283615/">mental health and wellbeing</a>, <a href="https://www.sciencedirect.com/science/article/pii/S0376871624001947">alcohol use</a> and <a href="https://doi.org/10.1016/j.chb.2021.106839">problematic social media use</a>.</p> <p>Social media use becomes a problem for people when they have difficulty controlling urges to use social media, have difficulty cutting back on use, and where the use has a negative impact on their everyday life.</p> <p>Doomscrolling is characterised by a need to constantly look at and <a href="https://www.bbc.com/worklife/article/20210226-the-darkly-soothing-compulsion-of-doomscrolling">seek out “bad” news</a>. Doomscrollers may constantly refresh their news feeds or stay up late to read bad news.</p> <p>While problematic social media use has been around for a while, doomscrolling seems to be a more recent phenomenon – <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7735659/">attracting research attention</a> during and following the pandemic.</p> <h2>What we tried to find out</h2> <p>In our study, we wanted to test the idea that FOMO leads individuals to engage in problematic use behaviours due to their difficulty in managing the “fear” in FOMO.</p> <p>The key factor, we thought, was <a href="https://link.springer.com/article/10.1023/b:joba.0000007455.08539.94">emotion regulation</a> – our ability to deal with our emotions. We know some people tend to be good at this, while others find it difficult. In fact, greater difficulties with emotion regulation was linked to experiencing <a href="https://www.sciencedirect.com/science/article/pii/S088761852100058X">greater acute stress related to COVID</a>.</p> <p>However, an idea that has been gaining attention recently is <a href="https://www.frontiersin.org/journals/psychology/articles/10.3389/fpsyg.2021.636919/full">interpersonal emotion regulation</a>. This means looking to others to help us regulate our emotions.</p> <p>Interpersonal emotion regulation can be helpful (such as “<a href="https://link.springer.com/article/10.1007/s11031-016-9569-3">affective engagement</a>”, where someone might listen and talk about your feelings) or unhelpful (such as “<a href="https://psycnet.apa.org/doiLanding?doi=10.1037%2F0012-1649.43.4.1019">co-rumination</a>” or rehashing problems together), depending on the context.</p> <p>In our analyses, we sought to uncover how both <em>intrapersonal</em> emotion regulation (ability to self-manage our own emotional states) and <em>interpersonal</em> emotion regulation (relying on others to help manage our emotions) accounted for the link between FOMO and problematic social media use, and FOMO and doomscrolling, respectively.</p> <h2>What we found – and what it might mean for the future of internet use</h2> <p>Our findings indicated that people who report stronger FOMO engage in problematic social media use because of difficulty regulating their emotions (intrapersonally), and they look to others for help (interpersonally).</p> <p>Similarly, people who report stronger FOMO are drawn to doomscrolling because of difficulty regulating their emotions intrapersonally (within themselves). However, we found no link between FOMO and doomscrolling through interpersonal emotion regulation.</p> <p>We suspect this difference may be due to doomscrolling being more of a solitary activity, occurring outside more social contexts that facilitate interpersonal regulation. For instance, there are probably fewer people with whom to share your emotions while staying up trawling through bad news.</p> <p>While links between FOMO and doomscrolling have been observed before, our study is among the first to try and account for this theoretically.</p> <p>We suspect the link between FOMO and doomscrolling may be more about having more of an online presence <em>while things are happening</em>. This would account for intrapersonal emotion regulation failing to help manage our reactions to “bad news” stories as they unfold, leading to doomscrolling.</p> <p>Problematic social media use, on the other hand, involves a more complex interpersonal context. If someone is feeling the fear of being “left out” and has difficulty managing that feeling, they may be drawn to social media platforms in part to try and elicit help from others in their network.</p> <h2>Getting the balance right</h2> <p>Our findings suggest the current discussions around <a href="https://www.nbcnews.com/news/us-news/psychology-group-says-infinite-scrolling-social-media-features-are-par-rcna147876">restricting social media use for young people</a>, while controversial, are important. We need to balance our need for social connection – which is happening increasingly online – with the <a href="https://www.biomedcentral.com/collections/spia#tab-3">detrimental consequences </a> associated with problematic internet use behaviours.</p> <p>It is important to also consider the nature of social media platforms and how they have changed over time. For example, adolescent social media use patterns across various platforms are <a href="https://link.springer.com/article/10.1007/s10964-019-01060-9">associated with</a> different mental health and socialisation outcomes.</p> <p>Public health policy experts and legislators have quite the challenge ahead of them here. Recent work has shown how loneliness is <a href="https://doi.org/10.1371/journal.pone.0190033">a contributing factor</a> to all-cause mortality (death from any cause).</p> <p>We have long known, too, that social connectedness is <a href="https://doi.org/10.1371/journal.pone.0190033">good for our mental health</a>. In fact, last year, the World Health Organization established a <a href="https://www.who.int/news/item/15-11-2023-who-launches-commission-to-foster-social-connection">Commission on Social Connection</a> to help promote the importance of socialisation to our lives.</p> <p>The recent controversy in the United States around the ownership of TikTok illustrates how central social media platforms are to our lives and ways of interacting with one another. We need to <a href="https://www.theguardian.com/commentisfree/article/2024/may/27/dominic-andre-tiktok-ban">consider the rights of individuals</a> to use them as they please, but understand that governments carry the responsibility of <a href="https://www.theguardian.com/technology/2023/apr/04/what-does-tiktoks-ban-on-australian-government-devices-mean-for-its-future">protecting users from harm</a> and safeguarding their privacy.</p> <hr /> <p><em>If you feel concerned about problematic social media use or doomscrolling, you can speak to a healthcare or mental health professional.

Cost of living: if you can’t afford as much fresh produce, are canned veggies or frozen fruit just as good?

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/evangeline-mantzioris-153250">Evangeline Mantzioris</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180"><em>University of South Australia</em></a></em></p> <p>The cost of living crisis is affecting how we spend our money. For many people, this means tightening the budget on the weekly supermarket shop.</p> <p>One victim may be fresh fruit and vegetables. Data from the <a href="https://www.abs.gov.au/media-centre/media-releases/australians-consuming-fewer-vegetables-fruit-and-less-milk#:%7E:text=Paul%20Atyeo%2C%20ABS%20health%20statistics,278%20to%20267%20to%20grams.%E2%80%9D">Australian Bureau of Statistics</a> (ABS) suggests Australians were consuming fewer fruit and vegetables in 2022–23 than the year before.</p> <p>The cost of living is likely compounding a problem that exists already – on the whole, Australians don’t eat enough fruit and vegetables. <a href="https://www.eatforhealth.gov.au/guidelines/australian-guide-healthy-eating">Australian dietary guidelines</a> recommend people aged nine and older should consume <a href="https://www.eatforhealth.gov.au/food-essentials/five-food-groups/fruit">two</a> serves of fruit and <a href="https://www.eatforhealth.gov.au/food-essentials/five-food-groups/vegetables-and-legumes-beans">five</a> serves of vegetables each day for optimal health. But in 2022 the <a href="https://www.abs.gov.au/statistics/health/health-conditions-and-risks/dietary-behaviour/latest-release">ABS reported</a> only 4% of Australians met the recommendations for both fruit and vegetable consumption.</p> <p>Fruit and vegetables are crucial for a healthy, balanced diet, providing a range of <a href="https://theconversation.com/were-told-to-eat-a-rainbow-of-fruit-and-vegetables-heres-what-each-colour-does-in-our-body-191337">vitamins</a> and minerals as well as fibre.</p> <p>If you can’t afford as much fresh produce at the moment, there are other ways to ensure you still get the benefits of these food groups. You might even be able to increase your intake of fruit and vegetables.</p> <h2>Frozen</h2> <p>Fresh produce is often touted as being the most nutritious (think of the old adage “fresh is best”). But this is not necessarily true.</p> <p>Nutrients can decline in transit from the paddock to your kitchen, and while the produce is stored in your fridge. Frozen vegetables may actually be higher in some nutrients such as <a href="https://pubmed.ncbi.nlm.nih.gov/25526594/">vitamin C and E</a> as they are snap frozen very close to the time of harvest. Variations in transport and storage can affect this slightly.</p> <p><a href="https://pubs.acs.org/doi/10.1021/jf504890k">Minerals</a> such as calcium, iron and magnesium stay at similar levels in frozen produce compared to fresh.</p> <p>Another advantage to frozen vegetables and fruit is the potential to reduce food waste, as you can use only what you need at the time.</p> <p>As well as buying frozen fruit and vegetables from the supermarket, you can freeze produce yourself at home if you have an oversupply from the garden, or when produce may be cheaper.</p> <p>A <a href="https://www.growveg.com.au/guides/freezing-vegetables-and-herbs-the-garden-foodie-version/">quick blanching</a> prior to freezing can improve the safety and quality of the produce. This is when food is briefly submerged in boiling water or steamed for a short time.</p> <p>Frozen vegetables won’t be suitable for salads but can be eaten roasted or steamed and used for soups, stews, casseroles, curries, pies and quiches. Frozen fruits can be added to breakfast dishes (with cereal or youghurt) or used in cooking for fruit pies and cakes, for example.</p> <h2>Canned</h2> <p>Canned vegetables and fruit similarly often offer a cheaper alternative to fresh produce. They’re also very convenient to have on hand. The <a href="https://nchfp.uga.edu/how/can#gsc.tab=0">canning process</a> is the preservation technique, so there’s no need to add any additional preservatives, including salt.</p> <p>Due to the cooking process, levels of heat-sensitive nutrients <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/jsfa.2825">such as vitamin C</a> will decline a little compared to fresh produce. When you’re using canned vegetables in a hot dish, you can add them later in the cooking process to reduce the amount of nutrient loss.</p> <p>To minimise waste, you can freeze the portion you don’t need.</p> <h2>Fermented</h2> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6723656/">Fermentation</a> has recently come into fashion, but it’s actually one of the oldest food processing and preservation techniques.</p> <p>Fermentation largely retains the vitamins and minerals in fresh vegetables. But fermentation may also enhance the food’s nutritional profile by creating new nutrients and allowing existing ones to be <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9352655/">absorbed more easily</a>.</p> <p>Further, fermented foods contain probiotics, which are beneficial for our <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10051273/">gut microbiome</a>.</p> <h2>5 other tips to get your fresh fix</h2> <p>Although alternatives to fresh such as canned or frozen fruit and vegetables are good substitutes, if you’re looking to get more fresh produce into your diet on a tight budget, here are some things you can do.</p> <p><strong>1. Buy in season</strong></p> <p>Based on supply and demand principles, buying local seasonal vegetables and fruit will always be cheaper than those that are imported out of season from other countries.</p> <p><strong>2. Don’t shun the ugly fruit and vegetables</strong></p> <p>Most supermarkets now sell “ugly” fruit and vegetables, that are not physically perfect in some way. This does not affect the levels of nutrients in them at all, or their taste.</p> <p><strong>3. Reduce waste</strong></p> <p>On average, an Australian household throws out <a href="https://www.ozharvest.org/food-waste-facts/">A$2,000–$2,500</a> worth of food every year. Fruit, vegetables and bagged salad are the <a href="https://www.ozharvest.org/food-waste-facts/">three of the top five foods</a> thrown out in our homes. So properly managing fresh produce could help you save money (and benefit <a href="https://endfoodwaste.com.au/why-end-food-waste/">the environment</a>).</p> <p>To minimise waste, plan your meals and shopping ahead of time. And if you don’t think you’re going to get to eat the fruit and vegetables you have before they go off, freeze them.</p> <p><strong>4. Swap and share</strong></p> <p>There are many websites and apps which offer the opportunity to swap or even pick up free fresh produce if people have more than they need. Some <a href="https://www.charlessturt.sa.gov.au/environment/sustainable-lifestyles/community-fruit-and-vege-swaps">local councils are also encouraging</a> swaps on their websites, so dig around and see what you can find in your local area.</p> <p><strong>5. Gardening</strong></p> <p>Regardless of how small your garden is you can always <a href="https://www.gardeningaustraliamag.com.au/best-vegies-grow-pots/">plant produce in pots</a>. Herbs, rocket, cherry tomatoes, chillies and strawberries all grow well. In the long run, these will offset some of your cost on fresh produce.</p> <p>Plus, when you have put the effort in to grow your own produce, <a href="https://mdpi-res.com/sustainability/sustainability-07-02695/article_deploy/sustainability-07-02695.pdf?version=1425549154">you are less likely to waste it</a>.<!-- Below is The Conversation's page counter tag.

Air travel exposes you to radiation – how much health risk comes with it?

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/timothy-j-jorgensen-239253">Timothy J. Jorgensen</a>, <a href="https://theconversation.com/institutions/georgetown-university-1239">Georgetown University</a></em></p> <p>In 2017, <a href="http://www.independent.ie/business/world/18-million-miles-and-counting-the-globes-top-business-traveller-35666790.html">business traveler Tom Stuker</a> was hailed as the world’s most frequent flyer, logging 18,000,000 miles of air travel on United Airlines over 14 years.</p> <p>That’s a lot of time up in the air. If Stuker’s traveling behaviors are typical of other business flyers, he may have eaten 6,500 <a href="http://www.airliners.net/forum/viewtopic.php?t=689041">inflight meals</a>, drunk 5,250 <a href="https://doi.org/10.1111/j.1708-8305.2009.00339.x">alcoholic beverages</a>, watched thousands of <a href="http://www.iata.org/publications/store/Pages/global-passenger-survey.aspx">inflight movies</a> and made around 10,000 visits to <a href="http://blog.thetravelinsider.info/2012/11/how-many-restrooms-are-enough-on-a-plane.html">airplane toilets</a>.</p> <p>He would also have accumulated a radiation dose equivalent to about 1,000 <a href="https://www.radiologyinfo.org/en/info.cfm?pg=safety-xray">chest x-rays</a>. But what kind of health risk does all that radiation actually pose?</p> <h2>Cosmic rays coming at you</h2> <p>You might guess that a frequent flyer’s radiation dose is coming from the airport security checkpoints, with their whole-body scanners and baggage x-ray machines, but you’d be wrong. The <a href="http://www.aapm.org/publicgeneral/AirportScannersPressRelease.asp">radiation doses to passengers from these security procedures</a> are trivial.</p> <p>The major source of radiation exposure from air travel comes from the flight itself. This is because at high altitude the <a href="http://www.altitude.org/why_less_oxygen.php">air gets thinner</a>. The farther you go from the Earth’s surface, the fewer molecules of gas there are per volume of space. Thinner air thus means fewer molecules to deflect incoming <a href="http://www.space.com/32644-cosmic-rays.html">cosmic rays</a> – radiation from outer space. With less <a href="http://www.bbc.co.uk/science/earth/atmosphere_and_climate/atmosphere">atmospheric shielding</a>, there is more exposure to radiation.</p> <p>The most extreme situation is for astronauts who travel entirely outside of the Earth’s atmosphere and enjoy none of its protective shielding. Consequently, they receive high radiation doses. In fact, it is the accumulation of radiation dose that is the limiting factor for the maximum length of manned space flights. Too long in space and <a href="https://www.nasa.gov/hrp/bodyinspace">astronauts risk cataracts, cancer and potential heart ailments</a> when they get back home.</p> <p>Indeed, it’s the radiation dose problem that is a major spoiler for <a href="http://www.space.com/34210-elon-musk-unveils-spacex-mars-colony-ship.html">Elon Musk’s goal of inhabiting Mars</a>. An extended stay on Mars, with its <a href="http://www.space.com/16903-mars-atmosphere-climate-weather.html">extremely thin atmosphere</a>, would be lethal due to the high radiation doses, notwithstanding Matt Damon’s successful Mars colonization in the movie <a href="https://www.youtube.com/watch?v=ej3ioOneTy8">“The Martian</a>.”</p> <h2>Radiation risks of ultra frequent flying</h2> <p>What would be Stuker’s cumulative radiation dose and what are his health risks?</p> <p>It depends entirely on how much time he has spent in the air. Assuming an <a href="http://hypertextbook.com/facts/2002/JobyJosekutty.shtml">average flight speed</a> (550 mph), Stuker’s 18,000,000 miles would translate into 32,727 hours (3.7 years) of flight time. The radiation dose rate at typical <a href="http://www.telegraph.co.uk/travel/travel-truths/why-do-planes-fly-so-high-feet/">commercial airline flight altitude</a> (35,000 feet) is about <a href="https://hps.org/publicinformation/ate/faqs/commercialflights.html">0.003 millisieverts per hour</a>. (As I explain in my book <a href="http://press.princeton.edu/titles/10691.html">“Strange Glow: The Story of Radiation</a>,” a millisievert or mSv is a unit of radiation dose that can be used to estimate cancer risk.) By multiplying the dose rate by the hours of flight time, we can see that Stuker has earned himself about 100 mSv of radiation dose, in addition to a lot of free airline tickets. But what does that mean for his health?</p> <p>The primary health threat at this dose level is an increased risk of some type of cancer later in life. Studies of atomic bomb victims, nuclear workers and medical radiation patients have <a href="https://doi.org/10.17226/11340">allowed scientists to estimate the cancer risk</a> for any particular radiation dose.</p> <p>All else being equal and assuming that low doses have risk levels proportionate to high doses, then an overall cancer risk rate of <a href="http://www.imagewisely.org/imaging-modalities/computed-tomography/medical-physicists/articles/how-to-understand-and-communicate-radiation-risk">0.005 percent per mSv</a> is a reasonable and commonly used estimate. Thus, Stuker’s 100-mSv dose would increase his lifetime risk of contracting a potentially fatal cancer by about 0.5 percent.</p> <h2>Contextualizing the risk</h2> <p>The question then becomes whether that’s a high level of risk. Your own feeling might depend on how you see your background cancer risk.</p> <p>Most people <a href="http://www.who.int/whr/2002/chapter3/en/index4.html">underestimate their personal risk of dying from cancer</a>. Although the exact number is debatable, it’s fair to say that <a href="https://www.cancer.org/cancer/cancer-basics/lifetime-probability-of-developing-or-dying-from-cancer.html">about 25 percent of men ultimately contract a potentially fatal cancer</a>. Stuker’s 0.5 percent cancer risk from radiation should be added to his baseline risk – so it would go from 25 percent to 25.5 percent. A cancer risk increase of that size is too small to actually measure in any scientific way, so it must remain a theoretical increase in risk.</p> <p>A 0.5 percent increase in risk is the same as one chance in 200 of getting cancer. In other words, if 200 male travelers logged 18,000,000 miles of air travel, like Stuker did, we might expect just one of them to contract a cancer thanks to his flight time. The other 199 travelers would suffer no health effects. So the chances that Stuker is the specific 18-million-mile traveler who would be so unlucky is quite small.</p> <p>Stuker was logging more air hours per year (greater than 2,000) than most pilots typically log (<a href="http://work.chron.com/duty-limitations-faa-pilot-17646.html">under 1,000</a>). So these airline workers would have risk levels proportionately lower than Stuker’s. But what about you?</p> <p>If you want to know your personal cancer risk from flying, estimate all of your commercial airline miles over the years. Assuming that the values and parameters for speed, radiation dose and risk stated above for Stuker are also true for you, dividing your total miles by 3,700,000,000 will give your approximate odds of getting cancer from your flying time.</p> <p>For example, let’s pretend that you have a mathematically convenient 370,000 total flying miles. That would mean 370,000 miles divided by 3,700,000,000, which comes out to be 1/10,000 odds of contracting cancer (or a 0.01 percent increase in risk). Most people do not fly 370,000 miles (equal to 150 flights from Los Angeles to New York) within their lifetimes. So for the average flyer, the increased risk is far less than 0.01 percent.</p> <p>To make your exercise complete, make a list of all the benefits that you’ve derived from your air travel over your lifetime (job opportunities, vacation travel, family visits and so on) and go back and look at your increased cancer risk again. If you think your benefits have been meager compared to your elevated cancer risk, maybe its time to rethink flying. But for many people today, flying is a necessity of life, and the small elevated cancer risk is worth the price.<!-- Below is The Conversation's page counter tag.

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

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

Stamp duty is holding us back from moving homes – we’ve worked out how much

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/nick-garvin-1453835">Nick Garvin</a>, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a></em></p> <p>If just one state of Australia, New South Wales, scrapped its stamp duty on real-estate transactions, about 100,000 more Australians would move homes each year, according to our <a href="https://e61.in/wp-content/uploads/2024/02/Stamp-duty-effects-on-purchases-and-moves.pdf">best estimates</a>.</p> <p>Stamp duty is an unquestioned part of buying a home in Australia – you put your details in an online mortgage calculator, and stamp duty is automatically deducted from the amount you have to contribute.</p> <p>It’s easy to overlook how much more affordable a home would be without it.</p> <p>That means it’s also easy to overlook how much more Australians would buy and move if stamp duty wasn’t there.</p> <p>The 2010 Henry Tax Review found stamp duty was <a href="https://treasury.gov.au/sites/default/files/2019-10/afts_final_report_part_2_vol_1_consolidated.pdf">inequitable</a>. It taxes most the people who most need to or want to move.</p> <p>The review reported: "Ideally, there would be no role for any stamp duties, including conveyancing stamp duties, in a modern Australian tax system. Recognising the revenue needs of the States, the removal of stamp duty should be achieved through a switch to more efficient taxes, such as those levied on broad consumption or land bases."</p> <p>But does stamp duty actually stop anyone moving? It’s a claim more often made than assessed, which is what our team at the <a href="https://e61.in/wp-content/uploads/2024/02/Stamp-duty-effects-on-purchases-and-moves.pdf">e61 Institute</a> set out to do.</p> <p>We used real-estate transaction data and a natural experiment.</p> <h2>What happened when Queensland hiked stamp duty</h2> <p>In 2011, Queensland hiked stamp duty for most buyers by removing some concessions for owner-occupiers at short notice.</p> <p>For owner-occupiers it increased stamp duty by about one percentage point, lifting the average rate from 1.26% of the purchase price to 2.27%.</p> <p>What we found gives us the best estimate to date of what stamp duty does to home purchases.</p> <p>A one percentage point increase in stamp duty causes the number of home purchases to decline by 7.2%.</p> <p>The number of moves (changes of address) falls by about as much.</p> <p>The effect appears to be indiscriminate. Purchases of houses fell about as much as purchases of apartments, and purchases in cities fell about as much as purchases in regions.</p> <p>Moves between suburbs and moves interstate dropped by similar rates.</p> <p>With NSW stamp duty currently averaging about <a href="https://conveyancing.com.au/need-to-know/stamp-duty-nsw">3.5%</a> of the purchase price, our estimates suggest there would be about 25% more purchases and moves by home owners if it were scrapped completely. That’s 100,000 moves.</p> <p>Victoria’s higher rate of stamp duty, about <a href="https://www.sro.vic.gov.au/rates-taxes-duties-and-levies/general-land-transfer-duty-property-current-rates">4.2%</a>, means if it was scrapped there would be about 30% more purchases. That’s another 90,000 moves.</p> <h2>Even low headline rates have big effects</h2> <p>The big effect from small-looking headline rates ought not to be surprising.</p> <p>When someone buys a home, they typically front up much less cash than the purchase price. While stamp duty seems low as a percentage of the purchase price, it is high as a percentage of the cash the buyer needs to find.</p> <p>Here’s an example. If stamp duty is 4% of the purchase price, and a purchaser pays $800,000 for a property with a mortgage deposit of $160,000, the $32,000 stamp duty adds 20%, not 4%, to what’s needed.</p> <p>If the deposit takes five years to save, stamp duty makes it six.</p> <p>A similar thing happens when an owner-occupier changes address. If the buyer sells a fully owned home for $700,000 and buys a new home for $800,000, the upgrade ought to cost them $100,000. A 4% stamp duty lifts that to $132,000.</p> <p>Averaged across all Australian cities, stamp duty costs about <a href="https://e61.in/wp-content/uploads/2024/02/Stepped-on-by-Stamp-Duty.pdf">five months</a> of after-tax earnings. In Sydney and Melbourne, it’s six.</p> <h2>Stamp duty has bracket creep</h2> <p>This cost has steadily climbed from around <a href="https://e61.in/wp-content/uploads/2024/02/Stepped-on-by-Stamp-Duty.pdf">six weeks</a> of total earnings in the 1990s. It has happened because home prices have climbed faster than incomes and because stamp duty has brackets, meaning more buyers have been pushed into higher ones.</p> <p>Replacing the stamp duty revenue that states have come to rely on would not be easy, but a switch would almost certainly help the economy function better.</p> <p>The more that people are able to move, the more they will move to jobs to which they are better suited, boosting productivity.</p> <p>The more that people downsize when they want to, the more housing will be made available for others.</p> <p>Our findings suggest the costs are far from trivial, making a switch away from stamp duty worthwhile, even if it is disruptive and takes time.<!-- Below is The Conversation's page counter tag.

How much sport will you be able to watch for free under proposed new Australian broadcast rules?

<p><em><a href="https://theconversation.com/profiles/hunter-fujak-290599">Hunter Fujak</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> and <a href="https://theconversation.com/profiles/david-rowe-16403">David Rowe</a>, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a></em></p> <p>Watching sport on television and other screens is integral to the <a href="https://researchdirect.westernsydney.edu.au/islandora/object/uws%3A57259">cultural lives of many Australians</a>.</p> <p>This is why, in 1995, the anti-siphoning scheme was introduced to ensure sport “<a href="http://www.tandfebooks.com/isbn/9780203758397">events of national importance and cultural significance</a>” would not be captured exclusively by pay TV at the expense of free-to-air coverage.</p> <p>There have been enormous <a href="https://www.taylorfrancis.com/chapters/edit/10.4324/9780429402265-5/television-tony-bennett-modesto-gayo-david-rowe-graeme-turner">changes in television</a> since and this analogue-era legislation is increasingly out of step with the modern digital media landscape.</p> <p>Critically, under current definitions, streaming services such as Netflix and Amazon fall outside a scheme restricting subscription broadcasters like Foxtel.</p> <p>The federal government <a href="https://anthonyalbanese.com.au/media-centre/labor-will-support-local-tv-free-sport-in-the-streaming-age">promised</a> before its election in 2022 to review the anti-siphoning scheme. Its subsequent <a href="https://www.aph.gov.au/Parliamentary_Business/Bills_Legislation/Bills_Search_Results/Result?bId=r7132">Communications Legislation Amendment (Prominence and Anti-siphoning) Bill 2023</a> is designed to close the “<a href="https://theconversation.com/streaming-platforms-will-soon-be-required-to-invest-more-in-australian-tv-and-films-which-could-be-good-news-for-our-screen-sector-198757">regulatory gap</a>” that has emerged within media law since Netflix’s launch in Australia in 2015.</p> <p>The Senate referred the bill to its Environment and Communications Legislation Committee. Its report has just been released and will help shape Australians’ access to sport media content.</p> <h2>The importance of prominence</h2> <p>“Prominence” refers to the discoverability of individual media applications, such as Netflix or 9Now, on the user homepage of smart televisions.</p> <p>The federal government is troubled by overseas services like YouTube and Amazon being immediately visible on smart televisions through commercial licensing agreements, effectively “burying” Australian free-to-air TV.</p> <p>Public service broadcaster SBS, for example, <a href="https://www.9news.com.au/national/anti-siphoning-prominence-laws-australia-free-to-air-tv-channels/87bc8ddd-4120-4542-864e-2c84a781411e">claimed</a> during Senate hearings that one television manufacturer demanded both a placement fee and a 15% share of revenue to feature on the television’s homepage.</p> <p>Prominence is crucial in sport because anti-siphoning legislation is based on the principle that, although in <a href="https://www.thenewdaily.com.au/finance/finance-news/2023/03/06/tv-habits-australia">general decline</a>, free-to-air TV is still the most effective, <a href="https://accan.org.au/files/Reports/ACCAN%20Research%20Snapshot%20How%20Australians%20Watch%20TV.pdf">low-cost, readily-accessed</a> vehicle for delivering premium sport to a majority of Australian households.</p> <h2>Anti-siphoning</h2> <p>While often criticised by <a href="https://www.infrastructure.gov.au/have-your-say/anti-siphoning-scheme-review">subscription media companies and many sports</a> as anti-competitive, anti-siphoning legislation is significantly responsible for the continued abundance of free major sport on our televisions.</p> <p>In a portent of the risks ahead, <a href="https://www.cricket.com.au/news/3807634/amazon-prime-video-secures-icc-broadcast-rights-in-australia-t20-odi-world-cup-world-test-championship-2024-27">International Cricket Council</a> World Cups will disappear from free-to-air television between 2024 and 2027, after the world governing body signed an exclusive four-year deal with streaming platform Amazon.</p> <p>The <a href="https://www.theage.com.au/sport/afl/afl-boss-flies-to-us-for-talks-with-media-companies-20220425-p5ag16.html">AFL</a> also reportedly met Amazon in 2022 as part of its media rights negotiations.</p> <p><a href="https://theconversation.com/regardless-of-the-rules-sport-is-fleeing-free-tv-for-pay-and-it-might-be-an-avalanche-154640">Loopholes</a> in the scheme are also being increasingly exploited. This problem was exposed in 2018 when <a href="https://www.cricket.com.au/news/3296093/tvs-antisiphon-list-and-cricket-explained">Australian one-day international cricket matches</a> went behind a paywall, despite being listed as free-to-air events.</p> <p>As <a href="https://www.news.com.au/entertainment/tv/streaming/nrl-calls-for-technologically-neutral-overhaul-to-sport-broadcasting/news-story/31fc06ab986e12c7e6f720df33d23ad1">Foxtel</a> told the Senate hearing, both Nine (Stan) and Ten (Paramount+) are now hybrid networks, able to move acquired sports from free-to-air broadcast to behind a streaming paywall.</p> <p>At present, free-to-air networks cannot be compelled to acquire the rights to any sport, broadcast them if they do, or refrain from on-selling them to a pay platform.</p> <h2>What are the implications for sport and other viewers?</h2> <p>The majority Senate report broadly supported the federal government’s existing <a href="https://minister.infrastructure.gov.au/rowland/media-release/exposure-draft-prominence-regulations-released">exposure draft</a>.</p> <p>Regarding prominence, this means free-to-air channel “tiles” will be highly visible when you turn on a new smart TV. A 12-month phased implementation of a prominence framework was recommended by the committee – and would only apply to new televisions.</p> <p>The committee also broadly accepted the draft bill’s anti-siphoning provisions, which will affect what and where sport is viewed by fans.</p> <p>First, the listed events will be expanded by 30% and incorporate more women’s and parasports. They include the AFLW and NRLW finals, NRLW State of Origin, and the Summer Paralympic Games.</p> <p>To provide counterbalancing benefits to subscription broadcasters, sport events not acquired by a free-to-air broadcaster will become more quickly available to subscription platforms (12 months before an event starts, rather than six months before). This provides subscription platforms with greater lead-in times to plan, organise and promote their content schedules.</p> <p>The most controversial recommendation related to the scope of anti-siphoning laws, affecting how Australian viewers can access sport in the medium term.</p> <p>It supported the government’s position, on grounds of excessive competitive advantage, that anti-siphoning should only apply to terrestrial broadcasting. This excludes digital rights for live streaming through broadcast video on demand apps such as 9Now, Seven+, iView and SBS On Demand.</p> <p>Commercial free-to-air broadcasters called this a “<a href="https://www.mediaweek.com.au/industry-reacts-to-prominence-and-anti-siphoning-findings/">nightmare scenario</a>”, as they <a href="https://www.freetv.com.au/access-to-local-tv-services-and-free-sport-under-threat-unless-laws-are-strengthened/">estimate</a> 50% of households will be watching TV online by 2027.</p> <p>For viewers without televisions connected to aerials, this could make major sport events on free-to-air TV unavailable. Although terrestrial TV is still the most <a href="https://intellectdiscover.com/content/journals/10.1386/jdmp_00098_1">universally available screen sport vehicle</a>, aerials are no longer routinely installed in new housing developments.</p> <p>Research by the <a href="https://www.acma.gov.au/television-research">Australian Communications and Media Authority</a>, though, indicates that free-to-air network claims about disappearing TV aerials are somewhat exaggerated. Nonetheless, as modernisation was a central justification for the anti-siphoning reforms, the strategic compromise over broadcast video on demand apps will inevitably be scrutinised.</p> <p>Notably, in a dissenting minority report, the Greens were unhappy the bill did not go far enough in either prominence or anti-siphoning. They reserved their right to reject it unless suitably amended to guarantee global corporations could not capture Australian sports rights.</p> <h2>What happens next?</h2> <p>The amended bill must pass through Parliament to become law, and its final shape and the fate of any amendments are as yet unknown.</p> <p>While it is widely, though not universally, acknowledged action is needed to protect free screen sport viewing, intense disagreement remains among competing interest groups over what is to be done now and in the future.</p> <p>To safeguard their viewing interests, Australian sport fans will need to watch these formidably technical debates as closely as their favourite sport contests.<!-- Below is The Conversation's page counter tag.

Think $5.50 is too much for a flat white? Actually it’s too cheap, and our world-famous cafes are paying the price

<p><em><a href="https://theconversation.com/profiles/emma-felton-143029">Emma Felton</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p>Even in a stubborn cost-of-living crisis, it seems there’s one luxury most Australians <a href="https://www.comparethemarket.com.au/news/what-australians-wont-give-up-cost-of-living-crisis-report/">won’t sacrifice</a> – their daily cup of coffee.</p> <p>Coffee sales have largely <a href="https://www.statista.com/statistics/866543/australia-domestic-consumption-of-coffee/">remained stable</a>, even as financial pressures have bitten over the past few years.</p> <p>So too have prices. Though many of us became upset when prices began to creep up last year, they’ve since largely settled in the range between $4.00 and $5.50 for a basic drink.</p> <p>But this could soon have to change. By international standards, Australian coffee prices are low.</p> <p>No one wants to pay more for essentials, least of all right now. But our independent cafes are struggling.</p> <p>By not valuing coffee properly, we risk losing the <a href="https://bizcup.com.au/australian-coffee-culture/">internationally renowned</a> coffee culture we’ve worked so hard to create, and the phenomenal quality of cup we enjoy.</p> <h2>Coffee is relatively cheap in Australia</h2> <p>Our recent survey of Australian capital cities found the average price of a small takeaway flat white at speciality venues is A$4.78.</p> <p>But in <a href="https://pabloandrustys.com.au/blogs/drinkbettercoffee/global-coffee-prices">some international capitals</a>, it’s almost double this, even after adjusting for local <a href="https://www.investopedia.com/updates/purchasing-power-parity-ppp/">purchasing power parity</a>.</p> <p><iframe id="gaplH" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/gaplH/" width="100%" height="400px" frameborder="0"></iframe></p> <p>In London, a small flat white costs about A$6.96. Singapore, A$8.42. In Athens, as much as A$9.95.</p> <h2>The cafe business is getting harder</h2> <p>Over the past few decades, coffee prices haven’t kept pace with input costs. In the early 2000s, after wages, food costs, utilities and rent, many cafes <a href="https://www.coffeecommune.com.au/blog-why-are-cafes-so-expensive/">earned healthy profit margins</a> as high as 20%.</p> <p>The <a href="https://www.ibisworld.com/au/industry/cafes-coffee-shops/2015/">most recent data from IBISWorld</a> show that while Australian cafe net profits have recovered from a drop in 2020, at 7.6%, they remain much lower than the Australian <a href="https://www.money.com.au/research/australian-business-statistics">average business profit margin of 13.3%</a>.</p> <p>For an independent owner operating a cafe with the <a href="https://www.ibisworld.com/au/industry/cafes-coffee-shops/2015/">average turnover of A$300,000</a>, this would amount to a meagre A$22,800 annual net profit after all the bills are paid.</p> <h2>What goes into a cup?</h2> <p>Just looking at the cost of raw inputs – milk, beans, a cup and a lid – might make the margin seem lucrative.

Green coffee price</strong></p> <p>Increasingly <a href="https://www.aa.com.tr/en/environment/brewing-crisis-how-climate-change-is-reshaping-coffee-production/3113886">subject to the effects</a> of climate change, the baseline commodity price of green (unroasted) coffee is <a href="https://perfectdailygrind.com/2024/02/demand-for-robusta-prices-record-high/">going up</a>.</p> <p>Arabica – the higher quality bean you’re most likely drinking at specialty cafes – is a more expensive raw product. Despite levelling off from post-pandemic highs, its price is still trending up. In 2018, it <a href="https://www.statista.com/statistics/675807/average-prices-arabica-and-robusta-coffee-worldwide/">sold</a> for US$2.93 per kilogram, which is projected to increase to US$4.38 dollars in 2025.</p> <p>Robusta coffee is cheaper, and is the type <a href="https://www.lavazza.com.au/en/coffee-secrets/difference-type-arabica-robusta-coffee">typically used to make instant coffee</a>. But serious drought in Vietnam has just pushed the price of robusta to an <a href="https://www.barchart.com/story/news/25094367/coffee-rallies-with-robusta-at-a-record-high-on-shrinking-coffee-output-in-vietnam">all-time high</a>, putting pressure on the cost of coffee more broadly.</p> <p><strong>2. Milk prices</strong></p> <p>The price of fresh milk has risen by <a href="https://cdn-prod.dairyaustralia.com.au/-/media/project/dairy-australia-sites/national-home/resources/reports/situation-and-outlook/situation-and-outlook-report-march-2024.pdf?rev=b0222df4b01b40d0ae36cf8ac7b01bc0">more than 20%</a> over the past two years, and remains at a peak.

Wages and utilities</strong></p> <p>Over the past year, Australian wages have grown at their <a href="https://ministers.treasury.gov.au/ministers/jim-chalmers-2022/media-releases/real-wages-growth-back">fastest rate</a> since 2009, which is welcome news for cafe staff, but tough on operators in a sector with low margins.</p> <p>Electricity prices remain elevated after significant inflation, but could <a href="https://www.sbs.com.au/news/article/heres-how-much-your-energy-bills-might-go-down-by-and-when/k8g00jheg">begin to fall mid-year</a>.</p> <h2>Specialty vs. commodity coffee: why price expectations create an industry divide</h2> <p>One of the key factors keeping prices low in Australia is consumer expectation.</p> <p>For many people coffee is a fundamental part of everyday life, a marker of livability. Unlike wine or other alcohol, coffee is not considered a luxury or even a treat, where one might expect to pay a little more, or reduce consumption when times are economically tough. We anchor on familiar prices.</p> <p><iframe id="oDbah" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/oDbah/" width="100%" height="400px" frameborder="0"></iframe></p> <p>Because of this, it really hurts cafe owners to put their prices up. In touch with their customer base almost every day, they’re acutely aware of how much inflation can hurt.</p> <p>But in Australia, a huge proportion of coffee companies are also passionate about creating a world-class product by only using “<a href="https://medium.com/@samandsunrise/why-is-specialty-coffee-so-expensive-6cf298935e4b#:%7E:text=Specialty%20Shops%20Feature%20High%20Grade%20Coffees&amp;text=Their%20coffees%20are%20hand%2Dpicked,even%20on%20the%20same%20tree.">specialty coffee</a>”. Ranked at least 80 on a quality scale, specialty beans cost significant more than commodity grade, but their production offers better working conditions for farmers and encourages more sustainable growing practices.</p> <p>Although not commensurate with the wine industry, there are similarities. Single origin, high quality beans are often sourced from one farm and demand higher prices than commodity grade coffee, where cheaper sourced beans are often combined in a blend.</p> <p>Running a specialty cafe can also mean roasting your own beans, which requires a big investment in expertise and equipment.</p> <p>It’s an obvious example of doing the right thing by your suppliers and customers. But specialty cafes face much higher operating costs, and when they’re next to a commodity-grade competitor, customers are typically unwillingly to pay the difference.</p> <h2>Approach price rises with curiosity, not defensiveness</h2> <p>When cafe owners put up their prices, we often rush to accuse them of selfishness or profiteering. But they’re often just trying to survive.</p> <p>Given the quality of our coffee and its global reputation, it shouldn’t surprise us if we’re soon asked to pay a little bit more for our daily brew.</p> <p>If we are, we should afford the people who create one of our most important “<a href="https://theconversation.com/how-cafes-bars-gyms-barbershops-and-other-third-places-create-our-social-fabric-135530">third spaces</a>” kindness and curiosity as to why. <!-- Below is The Conversation's page counter tag.

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

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

Why do airlines charge so much for checked bags? This obscure rule helps explain why

<p><em><a href="https://theconversation.com/profiles/jay-l-zagorsky-152952">Jay L. Zagorsky</a>, <a href="https://theconversation.com/institutions/boston-university-898">Boston University</a></em></p> <p>Five out of the six <a href="https://www.oag.com/blog/biggest-airlines-in-the-us">biggest U.S. airlines</a> have <a href="https://www.cnbc.com/2024/03/05/delta-is-the-latest-airline-to-raise-its-checked-bag-fee.html">raised their checked bag fees</a> since January 2024.</p> <p>Take American Airlines. In 2023, it cost US$30 to check a standard bag in with the airline; <a href="https://www.usatoday.com/story/travel/airline-news/2024/02/20/american-airlines-bag-fees-mileage-earning/72669245007/">today, as of March 2024, it costs $40</a> at a U.S. airport – a whopping 33% increase.</p> <p>As a <a href="https://www.bu.edu/questrom/">business school</a> <a href="https://www.bu.edu/questrom/profile/jay-zagorsky/">professor who studies travel</a>, I’m often asked why airlines alienate their customers with baggage fees instead of bundling all charges together. <a href="https://www.vox.com/2015/4/16/8431465/airlines-carry-on-bags">There are</a> <a href="https://www.usatoday.com/story/travel/columnist/2023/06/21/bag-fees-will-stay-a-while-cruising-altitude/70338849007/">many reasons</a>, but an important, often overlooked cause is buried in the U.S. tax code.</p> <h2>A tax-law loophole</h2> <p>Airlines pay the federal government <a href="https://www.ecfr.gov/current/title-26/chapter-I/subchapter-D/part-49/subpart-D">7.5% of the ticket price</a> when <a href="https://www.pwc.com/us/en/services/tax/library/aircraft-club-nov-2023-air-transport-excise-tax-rates-for-2024.html">flying people domestically, alongside other fees</a>. The airlines dislike these charges, with their <a href="https://www.airlines.org/dataset/government-imposed-taxes-on-air-transportation/">trade association arguing</a> that they boost the cost to the consumer of a typical air ticket by around one-fifth.</p> <p>However, the U.S. Code of Federal Regulations <a href="https://www.ecfr.gov/current/title-26/chapter-I/subchapter-D/part-49/subpart-D/section-49.4261-8">specifically excludes baggage</a> from the 7.5% transportation tax as long as “the charge is separable from the payment for the transportation of a person and is shown in the exact amount.”</p> <p>This means if an airline charges a combined $300 to fly you and a bag round-trip within the U.S., it owes $22.50 in tax. If the airline charges $220 to fly you plus separately charges $40 each way for the bag, then your total cost is the same — but the airline only owes the government $16.50 in taxes. Splitting out baggage charges saves the airline $6.</p> <p>Now $6 might not seem like much, but it can add up. Last year, passengers took <a href="https://www.transtats.bts.gov/Data_Elements.aspx?Data=1">more than 800 million trips on major airlines</a>. Even if only a fraction of them check their bags, that means large savings for the industry.</p> <p>How large? The government has <a href="https://www.bts.dot.gov/topics/airlines-and-airports/baggage-fees-airline-2023">tracked revenue from bag fees</a> for decades. In 2002, airlines charged passengers a total of $180 million to check bags, which worked out to around 33 cents per passenger.</p> <p>Today, as any flyer can attest, bag fees are a lot higher. Airlines collected over 40 times more money in bag fees last year than they did in 2002.</p> <p>When the full data is in for 2023, <a href="https://www.bts.dot.gov/baggage-fees">total bag fees</a> will likely top $7 billion, which is about $9 for the average domestic passenger. <a href="https://viewfromthewing.com/the-real-reason-airlines-charge-checked-bag-fees-and-its-not-what-you-think">By splitting out the cost of bags</a>, airlines avoided paying about half a billion dollars in taxes just last year.</p> <p>In the two decades since 2002, flyers paid a total of about $70 billion in bag fees. This means separately charging for bags saved airlines about $5 billion in taxes.</p> <p><iframe id="88MYD" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/88MYD/2/" width="100%" height="400px" frameborder="0"></iframe></p> <p>It seems clear to me that tax savings are one driver of the unbundling of baggage fees because of a quirk in the law.</p> <p>The U.S. government doesn’t apply the 7.5% tax to <a href="https://www.ecfr.gov/current/title-26/chapter-I/subchapter-D/part-49/subpart-D/section-49.4261-3">international flights that go more than 225 miles</a> beyond the nation’s borders. Instead, there are fixed <a href="https://www.airlines.org/dataset/government-imposed-taxes-on-air-transportation">international departure and arrival taxes</a>. This is why major airlines charge $35 to $40 <a href="https://www.aa.com/i18n/travel-info/baggage/checked-baggage-policy.jsp">for bags if you’re flying domestically</a>, but don’t charge a bag fee when you’re flying to Europe or Asia.</p> <h2>Do travelers get anything for that money?</h2> <p>This system raises an interesting question: Do baggage fees force airlines to be more careful with bags, since customers who pay more expect better service? To find out, I checked with the Bureau of Transportation Statistics, which has been <a href="https://www.bts.gov/content/mishandled-baggage-reports-filed-passengers-largest-us-air-carriersa">tracking lost luggage for decades</a>.</p> <p>For many years, it calculated the number of mishandled-baggage reports per thousand airline passengers. The government’s data showed mishandled bags peaked in 2007 with about seven reports of lost or damaged luggage for every thousand passengers. That means you could expect your luggage to go on a different trip than the one you are taking about once every 140 or so flights. By 2018, that estimate had fallen to once every 350 flights.</p> <p>In 2019, the government <a href="https://www.bts.gov/topics/airlines-and-airports/number-30a-technical-directive-mishandled-baggage-amended-effective-jan">changed how it tracks</a> mishandled bags, calculating figures based on the total number of bags checked, rather than the total number of passengers. The new data show about six bags per thousand checked get lost or damaged, which is less than 1% of checked bags. Unfortunately, the data doesn’t show improvement since 2019.</p> <p>Is there anything that you can do about higher bag fees? Complaining to politicians probably won’t help. In 2010, two senators <a href="https://www.nj.com/business/2010/04/us_senators_present_bill_to_ba.html">tried to ban bag fees</a>, and their bill went nowhere.</p> <p>Given that congressional action failed, there’s a simple way to avoid higher bag fees: <a href="https://www.cnn.com/travel/article/packing-expert-travel-world-handbag/index.html">travel light</a> and <a href="https://www.nytimes.com/2023/07/08/opinion/carry-on-packing-airlines-lost-luggage.html">don’t check any luggage</a>. It may sound tough not to have all your belongings when traveling, but it might be the best option as bag fees take off.<!-- Below is The Conversation's page counter tag.

Travel Trouble

Summer’s over, so how much sun can (and should) I get?

<p><em><a href="https://theconversation.com/profiles/katie-lee-228942">Katie Lee</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> and <a href="https://theconversation.com/profiles/rachel-neale-891731">Rachel Neale</a>, <a href="https://theconversation.com/institutions/qimr-berghofer-medical-research-institute-1811">QIMR Berghofer Medical Research Institute</a></em></p> <p>As we slide of out summer, you might be wondering how careful you need to be about sun exposure. Excessive exposure causes <a href="https://www.cancer.org.au/about-us/policy-and-advocacy/prevention-policy/national-cancer-prevention-policy/skin-cancer-statistics-and-issues/uv-radiation">skin cancer</a>, but sun exposure also has <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9976694/">benefits</a>. How do you balance the two?</p> <p>A new <a href="https://www.sciencedirect.com/science/article/pii/S1326020023052949?via%3Dihub">position statement</a> from cancer, bone health and other experts <a href="https://www.assc.org.au/wp-content/uploads/2023/01/Sun-Exposure-Summit-PositionStatement_V1.9.pdf">aims to help</a> Australians balance the good and bad effects of sun exposure by taking into account their skin colour, risk of skin cancer, and where they live.</p> <h2>What are the benefits of sunlight?</h2> <p>Ultraviolet (UV) radiation (the wavelengths in sunlight that cause skin cancer) also leads to vitamin D production. <a href="https://dermnetnz.org/topics/vitamin-d">Vitamin D</a> is very important for maintaining strong bones, and is likely to have <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9976694/">multiple other health benefits</a>.</p> <p>But vitamin D probably isn’t the whole story. Sunshine, including UV radiation, is thought to affect health in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9976694/">other ways</a> such as improving our mood and reducing the risk of autoimmune diseases and infections. So for many people, avoiding the sun and taking a vitamin D supplement may not be the best approach.</p> <h2>How much time does it take to make vitamin D?</h2> <p>It’s complicated, but for most people and most of the year across most of Australia, it’s a lot less than you think.</p> <p>The <a href="https://onlinelibrary.wiley.com/doi/10.1111/php.13854">amount of time needed</a> depends on the amount of skin covered by clothing and the intensity of UV radiation (indicated by the UV index). More skin exposed and higher UV index equate to less time needed.</p> <p>Both the UV index and the amount of the year that UV radiation is high increase as you get closer to the equator. In summer, all of Australia is bathed in sunshine. But in winter, opposite ends of the country have <a href="https://onlinelibrary.wiley.com/doi/10.1111/php.13854">very different exposures</a>.</p> <p>In summer, everybody except those with deeply pigmented skin can make enough vitamin D in <a href="https://www.sciencedirect.com/science/article/pii/S1326020023052949?via%3Dihub">just five minutes</a> between 9am and 3pm, anywhere in Australia, provided they are wearing shorts and a T-shirt.</p> <p>In winter it’s a different story. In <a href="https://www.sciencedirect.com/science/article/pii/S1326020023052949?via%3Dihub">Darwin and Brisbane</a>, 5–10 minutes between 10am and 3pm will do the trick, but in <a href="https://www.sciencedirect.com/science/article/pii/S1326020023052949?via%3Dihub">Hobart</a>, factoring in winter clothing, it will take nearly an hour in the middle of the day.</p> <p>Hover your mouse over the lines below to see the length of exposure needed at specific times of day.</p> <p><iframe id="X5szQ" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/X5szQ/" width="100%" height="400px" frameborder="0"></iframe></p> <p>Staying out for longer than needed doesn’t necessarily make more vitamin D, but it <a href="https://www.sciencedirect.com/science/article/pii/S1326020023052949?via%3Dihub#bib25">does cause skin damage</a>.</p> <h2>Hang on, what about those with darker skin?</h2> <p>People with deeply pigmented, brown to black skin accumulate both vitamin D and DNA damage at a much slower rate than people with lighter skin tones.</p> <p>When UV radiation hits a DNA strand, it causes the DNA to become distorted. If the distortion isn’t fixed, it will cause a mistake when the DNA is copied for a new cell, causing a permanent mutation that sometimes leads to cancer.</p> <p>Melanin, the brown pigment in the skin, absorbs UV photons before that can happen, and the high melanin content in the darkest skin tones provides <a href="https://faseb.onlinelibrary.wiley.com/doi/full/10.1096/fj.201701472R">60 times</a> as much UV protection as the small amount in very fair skin.</p> <p>The flip side is the risk of vitamin D deficiency is much higher than the risk of skin cancer.</p> <p>The new statement accounts for this by putting people into <a href="https://www.sciencedirect.com/science/article/pii/S1326020023052949?via%3Dihub">three groups</a> based on their risk of skin cancer, with specialised advice for each group.</p> <h2>Highest skin cancer risk</h2> <p>This includes people with very pale skin that burns easily and tans minimally, but also people with darker white or olive skin who can tan easily but have extra skin cancer risk factors because they:</p> <ul> <li>have had <strong>skin cancer</strong> before</li> <li>have a <strong>family history</strong> of melanomas</li> <li>have many <strong>moles</strong></li> <li>are taking <strong>immunosuppressant</strong> medications.</li> </ul> <p>For these people, the harms of sun exposure almost certainly <a href="https://www.sciencedirect.com/science/article/pii/S1326020023052949?via%3Dihub">outweigh the benefits</a>.</p> <p>These people should wear sunscreen every day the <a href="https://www.arpansa.gov.au/our-services/monitoring/ultraviolet-radiation-monitoring/ultraviolet-radiation-index">UV index</a> is forecast to get to <a href="https://www.assc.org.au/peak-health-bodies-recommend-new-approach-to-sunscreen-use/">three or more</a>, and use the <a href="https://www.cancer.org.au/cancer-information/causes-and-prevention/sun-safety/be-sunsmart">five sunsmart steps</a> whenever the UV index is above three:</p> <ul> <li><strong>slip</strong> on clothing covering as much of the body as possible</li> <li><strong>slop</strong> on SPF30+ sunscreen on areas that can’t be covered up</li> <li><strong>slap</strong> on a hat</li> <li><strong>seek</strong> shade</li> <li><strong>slide</strong> on sunglasses.</li> </ul> <p>They shouldn’t spend time outdoors deliberately to make vitamin D, but should discuss vitamin D supplements with their doctor.</p> <h2>Intermediate skin cancer risk</h2> <p>This means people with dark white/olive skin that sometimes burns but tans easily, and who don’t have other skin cancer risk factors.</p> <p>These people should still apply sunscreen as part of their usual routine on all days when the UV index is forecast to get to <a href="https://www.assc.org.au/peak-health-bodies-recommend-new-approach-to-sunscreen-use/">three or more</a>, but they can spend enough time outdoors to get a “dose” of vitamin D on most days of the week.</p> <p>Once the time needed for their vitamin D dose is up, they should also use the <a href="https://www.cancer.org.au/cancer-information/causes-and-prevention/sun-safety/be-sunsmart">slip-slop-slap-seek-slide</a> steps to avoid accumulating DNA damage.</p> <p>If they’re unable to do this because of health or lifestyle factors, like being housebound, working night shifts, or always covering up with clothing, they should see their doctor about whether they need vitamin D supplements.</p> <h2>Lowest skin cancer risk</h2> <p>This covers people with deeply pigmented brown to black skin that rarely or never burns.</p> <p>These people can <a href="https://www.sciencedirect.com/science/article/pii/S1326020023052949?via%3Dihub#bib14">safely spend enough time outdoors</a> to make vitamin D and get the other benefits of sunshine. But because more time is needed, it can be difficult, particularly when the weather is cold.

How much weight do you actually need to lose? It might be a lot less than you think

<p><em><a href="https://theconversation.com/profiles/nick-fuller-219993">Nick Fuller</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>If you’re one of the <a href="https://www.finder.com.au/new-years-resolutions-statistics">one in three</a> Australians whose New Year’s resolution involved losing weight, it’s likely you’re now contemplating what weight-loss goal you should actually be working towards.</p> <p>But type “setting a weight loss goal” into any online search engine and you’ll likely be left with more questions than answers.</p> <p>Sure, the many weight-loss apps and calculators available will make setting this goal seem easy. They’ll typically use a body mass index (BMI) calculator to confirm a “healthy” weight and provide a goal weight based on this range.</p> <p>Your screen will fill with trim-looking influencers touting diets that will help you drop ten kilos in a month, or ads for diets, pills and exercise regimens promising to help you effortlessly and rapidly lose weight.</p> <p>Most sales pitches will suggest you need to lose substantial amounts of weight to be healthy – making weight loss seem an impossible task. But the research shows you don’t need to lose a lot of weight to achieve health benefits.</p> <h2>Using BMI to define our target weight is flawed</h2> <p>We’re a society fixated on numbers. So it’s no surprise we use measurements and equations to score our weight. The most popular is BMI, a measure of our body weight-to-height ratio.</p> <p>BMI classifies bodies as underweight, normal (healthy) weight, overweight or obese and can be a useful tool for weight and health screening.</p> <p>But it shouldn’t be used as the single measure of what it means to be a healthy weight when we set our weight-loss goals. This is <a href="https://theconversation.com/using-bmi-to-measure-your-health-is-nonsense-heres-why-180412">because</a> it:</p> <ul> <li> <p>fails to consider two critical factors related to body weight and health – body fat percentage and distribution</p> </li> <li> <p>does not account for significant differences in body composition based on gender, ethnicity and age.</p> </li> </ul> <h2>How does losing weight benefit our health?</h2> <p>Losing just 5–10% of our body weight – between 6 and 12kg for someone weighing 120kg – can significantly improve our health in four key ways.</p> <p><strong>1. Reducing cholesterol</strong></p> <p>Obesity increases the chances of having too much low-density lipoprotein (LDL) cholesterol – also known as bad cholesterol – because carrying excess weight changes how our bodies produce and manage lipoproteins and triglycerides, another fat molecule we use for energy.</p> <p>Having too much bad cholesterol and high triglyceride levels is not good, narrowing our arteries and limiting blood flow, which increases the risk of heart disease, heart attack and stroke.</p> <p>But <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4987606/">research</a> shows improvements in total cholesterol, LDL cholesterol and triglyceride levels are evident with just 5% weight loss.</p> <p><strong>2. Lowering blood pressure</strong></p> <p>Our blood pressure is considered high if it reads more than 140/90 on at least two occasions.</p> <p>Excess weight is <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7082272/">linked to</a> high blood pressure in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7082272/">several ways</a>, including changing how our sympathetic nervous system, blood vessels and hormones regulate our blood pressure.</p> <p>Essentially, high blood pressure makes our heart and blood vessels work harder and less efficiently, damaging our arteries over time and increasing our risk of heart disease, heart attack and stroke.</p> <p>Like the improvements in cholesterol, a 5% weight loss <a href="https://onlinelibrary.wiley.com/doi/10.1002/oby.21358">improves</a> both systolic blood pressure (the first number in the reading) and diastolic blood pressure (the second number).</p> <p>A <a href="https://www.ahajournals.org/doi/10.1161/01.hyp.0000094221.86888.ae">meta-analysis of 25 trials</a> on the influence of weight reduction on blood pressure also found every kilo of weight loss improved blood pressure by one point.</p> <p><strong>3. Reducing risk for type 2 diabetes</strong></p> <p>Excess body weight is the primary manageable risk factor for type 2 diabetes, particularly for people carrying a lot of visceral fat around the abdomen (belly fat).</p> <p>Carrying this excess weight can cause fat cells to release pro-inflammatory chemicals that disrupt how our bodies regulate and use the insulin produced by our pancreas, leading to high blood sugar levels.</p> <p>Type 2 diabetes can lead to serious medical conditions if it’s not carefully managed, including damaging our heart, blood vessels, major organs, eyes and nervous system.</p> <p><a href="https://www.nejm.org/doi/full/10.1056/nejmoa012512">Research</a> shows just 7% weight loss reduces risk of developing type 2 diabetes by 58%.</p> <p><strong>4. Reducing joint pain and the risk of osteoarthritis</strong></p> <p>Carrying excess weight can cause our joints to become inflamed and damaged, making us more prone to osteoarthritis.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/21425246/">Observational studies</a> show being overweight doubles a person’s risk of developing osteoarthritis, while obesity increases the risk fourfold.</p> <p>Small amounts of weight loss alleviate this stress on our joints. <a href="https://pubmed.ncbi.nlm.nih.gov/15986358/">In one study</a> each kilogram of weight loss resulted in a fourfold decrease in the load exerted on the knee in each step taken during daily activities.</p> <h2>Focus on long-term habits</h2> <p>If you’ve ever tried to lose weight but found the kilos return almost as quickly as they left, you’re not alone.</p> <p>An <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5764193/">analysis</a> of 29 long-term weight-loss studies found participants regained more than half of the weight lost within two years. Within five years, they regained more than 80%.</p> <p>When we lose weight, we take our body out of its comfort zone and trigger its survival response. It then counteracts weight loss, triggering several <a href="https://pubmed.ncbi.nlm.nih.gov/25896063/">physiological responses</a> to defend our body weight and “survive” starvation.</p> <p>Just as the problem is evolutionary, the solution is evolutionary too. Successfully losing weight long-term comes down to:</p> <ul> <li> <p>losing weight in small manageable chunks you can sustain, specifically periods of weight loss, followed by periods of weight maintenance, and so on, until you achieve your goal weight</p> </li> <li> <p>making gradual changes to your lifestyle to ensure you form habits that last a lifetime.</p> </li> </ul> <p>Setting a goal to reach a healthy weight can feel daunting. But it doesn’t have to be a pre-defined weight according to a “healthy” BMI range. Losing 5–10% of our body weight will result in immediate health benefits.</p> <p><em>At the Boden Group, Charles Perkins Centre, we are studying the science of obesity and running clinical trials for weight loss.

15 hacks that make running errands so much better

<p><strong>Run errands during the week</strong></p> <p>More than 90 per cent of people do errands on the weekends, meaning shops will be packed and traffic will be a nightmare. Running errands on a weeknight will get you in and out in half the time. Once the kids are in bed, have one parent stay home while the other drives to the shops. You’ll miss the crowds and keep your weekend free for fun and family.</p> <p><strong>Turn on a podcast</strong></p> <p>Radio music – and its deejays and commercials – can get intense. Switch off the FM and plug in your phone so you can listen to a podcast or audiobook. You’ll be more relaxed, and the time will fly as you get engrossed in the story.</p> <p><strong>Make the most of your time</strong></p> <p>Never run out for just one task. Save time, petrol, and stress by getting more than one thing done when you’re out of the house. After dropping your child off at soccer practice, drop off your dry cleaning or pick up the milk from the supermarket.</p> <p><strong>Set up an errand centre in your home</strong></p> <p>Keeping all the objects you’ll need to complete your errands – packages to be mailed, dry cleaning to be delivered, library books to be returned – in one place will make it easy to get out the door when you get the chance. Designate a space by the door or in your car as a visual reminder of what needs to get done.</p> <p><strong>Buy in bulk</strong></p> <p>Picking up big batches of items like toilet paper, dog food, and tampons means fewer trips to the supermarket and less time running errands. Plus, you save money by buying bulk packages or stocking up while the items are on sale.</p> <p><strong>Use long lines for "me time"</strong></p> <p>Instead of griping about how long your wait to the cash register is, think of it as a few peaceful moments to yourself. Close your eyes (don’t be self-conscious!) and imagine yourself sitting on a quiet beach or getting a massage. Take several deep breaths while you mentally escape to that place. You’ll be much more relaxed, and you can wait in line with less frustration.</p> <p><strong>Practice mindfulness</strong></p> <p>Performing a ‘walking meditation’ while you shop will keep you engaged with your task instead of letting your mind wander to other stressors. By the end of your trip, you’ll have more energy and less frustration. Pay attention to the bright colours of the produce, the scents wafting from the bakery, and the feeling of each step you take.</p> <p><strong>Do someone else's errands</strong></p> <p>If you have an elderly neighbour or know a mother with young kids, offer to add some of their tasks to your to-do list. Studies have shown that helping others can reduce stress.</p> <p><strong>Tune out</strong></p> <p>Instead of drowning out your thoughts with music, keep the radio off when you’re driving and allow your own thoughts to come to you. The stimuli of everyday life can be overwhelming, so this is your chance to recharge your energy in the silence.</p> <p><strong>Keep a grocery list on your phone</strong></p> <p>You probably buy the same things on most of your grocery runs. Instead of writing a new list every week, keep an ongoing list on your phone, which makes it easy to add and remove items. Organise your list in the order you’ll find them at the supermarket. For instance, if you start near the produce section, write the fruits and vegetables first.</p> <p><strong>Reward yourself </strong></p> <p>To keep yourself motivated while you’re out, add a little luxury to your shopping list. Treat yourself with nice bath soap, a bouquet of flowers, or your favourite craft beer.</p> <p><strong>Keep an ongoing errands list</strong></p> <p>Write down your usual tasks, along with the ones you keep forgetting to do, like buying socks for your child or making a vet appointment for the dog, in a notepad. Carry it with you so you don’t miss anything when you’re out. When you’re home, stash it where the rest of your family can access it and jot down their needs.</p> <p><strong>Buy online as much as possible </strong></p> <p>The possibilities are endless: order groceries, buy stamps, cash checks, and renew library books online. Giving your credit card number over a secured server is safer than stating your number over the phone, and sometimes safer than handing your card over at a store.</p> <p><strong>Alternate tasks with your neighbours </strong></p> <p>Make a deal with your neighbours in which you do the grocery shopping one week, and they take care of it the next. You can watch each other’s kids when it’s your turn to stay home, and both of you will make fewer trips to the supermarket. Or plan to go grocery shopping with a friend. You’ll have more fun with the social support, and your kids might behave better with someone else present.</p> <p><strong>Have dad run errands with the kids</strong></p> <p>Kids who cook, clean, and run errands with their dads have more friends and are better behaved, according to a University of California study. Make sure your partner (or you, if you’re a dad) takes the kids along every now and then. As a bonus, wives of men who do chores with their kids find their husbands more attractive.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/culture/15-hacks-that-make-running-errands-so-much-better?pages=1" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>
