What causes the itch in mozzie bites? And why do some people get such a bad reaction?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/cameron-webb-6736">Cameron Webb</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Are you one of these people who loathes spending time outdoors at dusk as the weather warms and mosquitoes start biting? Female mosquitoes <a href="https://www.annualreviews.org/content/journals/10.1146/annurev-ento-120811-153618">need blood</a> to develop their eggs. Even though they take a tiny amount of our blood, they can leave us with itchy red lumps that can last days. And sometimes something worse. So why does our body react and itch after being bitten by a mosquito? And why are some people more affected than others? <h2>What happens when a mosquito bites?</h2> Mosquitoes are attracted to warm blooded animals, including us. They’re attracted to the <a href="https://www.cambridge.org/core/journals/bulletin-of-entomological-research/article/abs/role-of-carbon-dioxide-in-hostfinding-by-mosquitoes-diptera-culicidae-a-review/2506B86EF63852B2D02EC3FCEE1E3B8B">carbon dioxide</a> we exhale, our body temperatures and, most importantly, <a href="https://www.abc.net.au/news/2024-11-08/mosquitoes-climate-change-skin/104548122">the smell of our skin</a>. The <a href="https://www.cell.com/trends/parasitology/abstract/S1471-4922(21)00237-3">chemical cocktail</a> of odours from bacteria and sweat on our skin <a href="https://www.cell.com/current-biology/fulltext/S0960-9822(23)00532-8">sends out a signal</a> to hungry mosquitoes. <a href="https://www.sciencedirect.com/science/article/pii/S2667114X21000522">Some people’s</a> skin smells more appealing to mosquitoes, and they’re more likely to be bitten than others. Once the mosquito has made its way to your skin, things get a little gross. The mosquito pierces your skin with their “proboscis”, their feeding mouth part. But the proboscis isn’t a single, straight, needle-like tube. There are multiple tubes, <a href="https://www.npr.org/sections/health-shots/2016/06/07/480653821/watch-mosquitoes-use-6-needles-to-suck-your-blood">some designed</a> for sucking and some for spitting. Once their mouth parts have been inserted into your skin, the mosquito will inject some saliva. This contains a mix of chemicals that gets the blood flowing better. There has even been a suggestion that future medicines could be inspired by the <a href="https://www.sydney.edu.au/news-opinion/news/2018/03/29/mosquito-saliva-vital-to-the-discovery-of-future-drugs.html">anti-blood clotting properties</a> of mosquito saliva. It’s not the stabbing of our skin by the mosquito’s mouth parts that hurts, it’s the mozzie spit our bodies don’t like. <h2>Are some people allergic to mosquito spit?</h2> Once a mosquito has injected their saliva into our skin, a variety of reactions can follow. For the lucky few, nothing much happens at all. For most people, and irrespective of the type of mosquito biting, <a href="https://www.frontiersin.org/journals/immunology/articles/10.3389/fimmu.2022.1024559/full">there is some kind of reaction</a>. Typically there is <a href="https://www.sciencedirect.com/science/article/abs/pii/S0161589023002304?via%3Dihub">redness and swelling of the skin</a> that appears within a few hours, but often more quickly, after just a few minutes. Occasionally, the reaction can cause pain or discomfort. Then comes the <a href="https://www.abc.net.au/news/health/2023-01-20/mosquito-bites-itchy-calamine-heat-ice-antihistamine-toothpaste/101652608">itchiness</a>. Some people do suffer severe reactions to mosquito bites. It’s a condition often referred to as “<a href="https://www.webmd.com/allergies/what-is-skeeter-syndrome">skeeter syndrome</a>” and is an allergic reaction caused by the protein in the mosquito’s saliva. This can cause large areas of swelling, blistering and fever. The chemistry of mosquito spit hasn’t really been well studied. But it has been shown that, for those who do suffer allergic reactions to their bites, the <a href="https://www.sciencedirect.com/science/article/abs/pii/S0091674904022183">reactions may differ</a> depending on the type of mosquito biting. We all probably get more tolerant of mosquito bites as we get older. Young children are certainly more likely to suffer more following mosquito bites. But as we get older, the reactions are less severe and may pass quickly without too much notice. <h2>How best to treat the bites?</h2> Research into treating bites <a href="https://linkinghub.elsevier.com/retrieve/pii/S0161589023002304">has yet to provide</a> a single easy solution. There are many <a href="https://www.healthline.com/health/outdoor-health/home-remedies-for-mosquito-bites">myths and home remedies</a> about what works. But there is little scientific evidence supporting their use. The best way to treat mosquito bites is by applying a cold pack to reduce swelling and to keep the skin clean to avoid any secondary infections. Antiseptic creams and lotions may also help. There is some evidence that <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC10309056/">heat may alleviate</a> some of the discomfort. It’s particularly tough to keep young children from scratching at the bite and breaking the skin. This can form a nasty scab that may end up being worse than the bite itself. Applying an anti-itch cream may help. If the reactions are severe, <a href="https://www.healthdirect.gov.au/insect-bites-and-stings">antihistamine medications</a> may be required. <h2>To save the scratching, stop the bites</h2> Of course, it’s better not to be bitten by mosquitoes in the first place. Topical <a href="https://theconversation.com/insect-repellents-work-but-there-are-other-ways-to-beat-mosquitoes-without-getting-sticky-171805">insect repellents</a> are a safe, effective and affordable way to reduce mosquito bites. Covering up with loose fitted long sleeved shirts, long pants and covered shoes also provides a physical barrier. <a href="https://theconversation.com/are-mosquito-coils-good-or-bad-for-our-health-88548">Mosquito coils and other devices</a> can also assist, but should not be entirely relied on to stop bites. There’s another important reason to avoid mosquito bites: millions of people around the world suffer from mosquito-borne diseases. More than <a href="https://www.who.int/news-room/fact-sheets/detail/malaria">half a million people die</a> from malaria each year. In Australia, <a href="https://journals.plos.org/plospathogens/article?id=10.1371/journal.ppat.1005070">Ross River virus</a> infects more than 5,000 people every year.

Aldi boss reveals why their supermarkets are always cheaper

Aldi bosses have revealed why their supermarkets are always cheaper than Coles and Woolworths after being quizzed by the ACCC. As part of the government crackdown on the supermarket duopoly in Australia, Aldi Australia national buying managing director Jordan Lack revealed the key reason why Aldi's prices are always lower. According to Lack, by keeping stores smaller, having fewer staff, and selling fewer items, prices are able to be kept lower than at other major supermarkets. "All of those little things ensure that we can keep our costs down and pass that onto the consumer," Lack said. Aldi says its supermarket shelves carry a range of only 1,800 items while Coles and Woolworths have more like 20,000 or 25,000. For example, a shopper looking for raspberry jam at Coles would have seven brands to choose from, while a Woolies shopper would see eight different brands, as Aldi only offers one brand. The ACCC Inquiry was told that is a big part of how Aldi can be anywhere between 10 per cent and a third less expensive than Coles and Woolworths. "We believe that incremental range adds costs and complexity through our supply chain," Lack said. Retail expert Gary Mortimer agreed, saying "When you're dealing with less choice and fewer items you're dealing with fewer suppliers, fewer wholesalers and you get the economies of scale."

For some people dying alone is not such a bad thing – here’s why

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/glenys-caswell-142188">Glenys Caswell</a>, <a href="https://theconversation.com/institutions/university-of-nottingham-1192">University of Nottingham</a> It seems so obvious that no one should die alone that we never talk about it, but people do often die when they are alone. Sometimes they die in a way that suggests they prefer to be alone as they are coming to the end of their lives. So is it really such a bad thing to be alone when you die? When a person is dying in a hospital or a care home it is common for the nurses caring for them to summon their family. Many people will have the experience of trying to <a href="http://journals.sagepub.com/doi/abs/10.2190/OM.55.3.d">keep vigil beside a family member</a>. It is hard – as everyday life goes on regardless – and it can be emotionally exhausting. Sometimes, the relative will die when their family have gone to make a phone call or get a cup of tea, leaving the family feeling distressed and guilty for not being there when they died. There is plenty of research literature, from many countries, devoted to trying to decide <a href="http://www.sciencedirect.com/science/article/pii/S0885392415001578">what makes a good death</a>. There are differences to be found between countries, but similarities too. One similarity is a belief that <a href="http://www.sciencedirect.com/science/article/pii/S106474811600138X?via%3Dihub">no one should die alone</a>. This idea sits well with the view of dying that can be found in many different places. When interviewed as research participants, health professionals – and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2904589/">nurses in particular</a> – commonly say that no one should die alone. There are also many cultural references that suggest that to die alone is a bad thing. Consider, for example, the death of Ebenezer Scrooge in Dickens’s <a href="https://www.gutenberg.org/files/46/46-h/46-h.htm">A Christmas Carol</a>, or the death of Nemo, the law writer in <a href="http://www.gutenberg.org/files/1023/1023-h/1023-h.htm">Bleak House</a>. These are both sad, dark, lonely deaths of a kind to be avoided. Celebrity deaths, such as those of comedian and actress <a href="https://www.theguardian.com/culture/2016/apr/20/victoria-wood-dies-aged-62-comedian">Victoria Wood</a> or <a href="http://www.bbc.co.uk/news/entertainment-arts-35278872">David Bowie</a>, are described in the news as peaceful or good when they are surrounded by family. Ordinary people who die alone make the news when the person’s body is undiscovered for a long time. When this happens the death is likely to be described in <a href="http://www.sciencedirect.com/science/article/pii/S027795360300577X?via%3Dihub">negative terms</a>, such as shocking, lonely, tragic or as a sad indictment of society. <h2>Some people prefer to be alone</h2> Of course, it may be the case that many people would prefer to have their family around them when they are dying. But there is <a href="http://www.tandfonline.com/doi/full/10.1080/21582041.2015.1114663">evidence</a> that suggests that some people would <a href="http://www.sciencedirect.com/science/article/pii/S0277953615003482?via%3Dihub">prefer to be alone </a> as they are coming to the end of their lives. My own <a href="http://www.tandfonline.com/doi/full/10.1080/13576275.2017.1413542">research</a> found that while hospice-at-home nurses believe that no one should die alone, they had seen cases where a person died after their family members had left the bedside. The nurses believed that some people just want to be on their own when they are dying. They also thought that people may have a measure of control over when they die, and choose to do so when their family are not around. In the same study, I also talked to older people who were living alone to find out their views about dying alone. I was intrigued to learn that dying alone was not seen as something that is automatically bad, and for some of the older people it was to be preferred. For some people in this group, dying was not the worst thing that could happen – being trapped in a care home was considered to be far worse than dying alone. Cultural representations of dying suggest that being alone while dying is a dreadful thing. This view is supported by healthcare policy and the practices of health professionals, such as nurses. But we all know people who prefer to be left alone when they are ill. Is it so surprising then that some might wish to be alone when they are dying? It is time we began to talk about this and to accept that we want different things in our dying as we do in our living. Openness created through discussion might also help to remove some of the guilt that family members feel when they miss the moment of their relative’s death.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/90034/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/glenys-caswell-142188">Glenys Caswell</a>, Senior Research Fellow, <a href="https://theconversation.com/institutions/university-of-nottingham-1192">University of Nottingham</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Borrowing money isn’t always a bad thing – debt can be a sensible way to build wealth

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/bomikazi-zeka-680577">Bomikazi Zeka</a>, <a href="https://theconversation.com/institutions/university-of-canberra-865">University of Canberra</a> Debt, in some form or another, is part of our financial profiles whether we like it or not. And it can be a useful way to build wealth if it is managed carefully and wisely. For example, you may borrow money from the bank to buy an asset – a resource of economic value that generates income from its productive use. Investment property is an example. So investing in an income-producing property can be a good idea. If you are already in the property market, the home equity you’ve accumulated – the share of the property value that’s yours – can help you buy a second property. This time, you may not need a deposit as big as the initial investment. In the event that the rental market is booming and your tenants pay you more than what you repay on the loan, municipal rates and property manager fees, then the wealth-building machine will start to run itself. But debt makes many people uncomfortable. In South Africa, a person earning R20,000 a month commits on average <a href="https://businesstech.co.za/news/finance/585372/south-africas-middle-class-is-in-serious-trouble-right-now/">63% of their salary to repaying unsecured debt</a> – such as credit cards, personal loans, overdrafts or “buy now, pay later” facilities. As a general guideline, it’s suggested that <a href="https://www.investopedia.com/terms/d/dti.asp">no more than 40%</a> of your income should be used to service debt. Financial anxiety has its roots in some misconceptions. The main one is that all debt is bad. This isn’t true. Prudent borrowing to buy an asset can help build wealth in the medium to long term. So fears about debt need to be weighed against a broader understanding of wealth accumulation. Well-managed debt can play a role in that process. Here are the four biggest misconceptions about debt. Recognising them will help you develop a more nuanced approach to debt. <h2>The misconceptions</h2> All debt is bad debt. Indeed, debt is a problem when you can no longer manage it and it starts to manage you. One of the simplest ways to tell whether debt is working for you or against you is through “leveraging”. This refers to the use of debt to acquire an asset that is worth more than the value of the debt. It’s also known as positive or favourable leveraging. People who take out unsecured loans are leveraging unfavourably when the debt is driven by consumption. Often there’s nothing to show for what you’ve spent. Unsecured loans also tend to charge higher interest rates to compensate for the lack of collateral. Only financially reckless people are in debt. This is the next misconception. Second to unsecured loans, most South African consumer debt portfolios are taken up by <a href="https://businesstech.co.za/news/wealth/617685/these-income-levels-in-south-africa-owe-the-most-debt/">home loans</a>. The most realistic way to gain entry into the housing market is through a mortgage. You’re doing the right thing if your mortgage is paid off within a reasonable time. This will mean that, in the long term, the value of the property will surpass the home loan amount that was taken out to buy the property in the first place. But there are two misconceptions related specifically to mortgages. After you’ve paid the mortgage deposit, you won’t have other fees to pay. This isn’t correct. Banks charge a fee to open and close a home loan account. There can also be a penalty when a home loan is repaid prematurely. So be sure to read the fine print about discharge fees or closing costs. If you stick to the repayment amount for your mortgage, you’ll be able to repay the loan quickly. This isn’t true – even if interest rates fall and your mortgage repayments decline, your home loan is most likely tied to a loan term of 20 to 30 years. Many banks will quote a monthly mortgage repayment amount that seems affordable at face value but is in fact based on a 20-year term period. Banks are businesses and it works in their favour if you take longer to repay your mortgage because that translates into more interest repayments. The longer the duration of the home loan, the more interest you pay, the more profit they make. If it takes over 20 years to repay a bond, it’s often the case that the value of the interest repayments exceeds the initial loan amount. Home loan calculators are a useful tool that can help you assess how much you could afford to repay on a home loan depending on the deposit saved, if interest rates change and how long it will take you to repay the mortgage with topped-up contributions. It is essential to have a goal for when you’d like to finish paying off your mortgage and a plan in place to achieve this goal. If you don’t do this you could become a mortgage prisoner. <h2>Keeping your eye on the prize</h2> As we’re about to conclude the year and enter the festive season, it’s a good time to remember your financial goals and not let your guard down by unconsciously swiping or tapping that credit card. “Janu-worry” is around the corner, and so is the financial anxiety that comes with it. But it need not be the case. Debt can either be the cure or the cause of your financial position. Reconsider spending patterns that prompt you to use your credit card. Too much debt over short periods is an irregular spending pattern that is a warning sign. There’s no harm in buying what you can afford or staying in your financial lane if the alternative forces you to sacrifice your hard-earned income on servicing consumption-driven debt. For better or worse, debt is a part of our financial portfolios. But the road to financial empowerment is not always easy – financial planning can help you keep your eye on the prize.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/192630/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/bomikazi-zeka-680577">Bomikazi Zeka</a>, Assistant Professor in Finance and Financial Planning, <a href="https://theconversation.com/institutions/university-of-canberra-865">University of Canberra</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

“Is it really that bad?”: New mum slammed for baby name choice

One woman has taken to social media to explain her dilemma after people around her made her second-guess the name she and her husband chose for their unborn son. The woman shared her situation on Reddit, and explained that the name has a special family significance to her, but so far people around her have absolutely hated it. "My grandpa was my favourite person in the whole world. Growing up, I always loved his name because I thought it was unique and I loved him. I always said if I had a son I would name him after my grandpa," she explained in the post. "Now I'm pregnant, and the very few people I've told the name to HATE IT. The name is Earl. Is it really that bad?" She added that she doesn't want her son to grow up hating his name, but she still wants to use it as it is so special to her. "Few other things: husband is on board and loves it, and it does sound really nice with our last name," she added. Many of the commenters urged her to go with the name if she loves it and to disregard what anyone else says. "This. Is. Your. Baby You don't need to poll the audience or tell anyone the baby's name before he is born. Protect your peace, and Earl's," replied one person. "I love Earl! Easy to say and spell. Uncommon but not made up. The emotional connection is wonderful too!" commented another. "It's a lovely name!!! Don't let other people shame you out of using it because you'll regret listening to them later," a third person assured her. "Earl is dated and country but it's cute and it means something to you and you both love it. It will be fine," another woman said. Some suggested that if she was really struggling with the name after the hate she received, there are other ways to incorporate it. "It's extremely dated but not bad. I personally think it's better as a middle name," replied one person. Image: Shutterstock

Retiring early can be bad for the brain

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/plamen-v-nikolov-1112610">Plamen V Nikolov</a>, <a href="https://theconversation.com/institutions/binghamton-university-state-university-of-new-york-2252">Binghamton University, State University of New York</a> The <a href="https://theconversation.com/us/topics/research-brief-83231">Research Brief</a> is a short take about interesting academic work. <h2>The big idea</h2> People who retire early suffer from accelerated cognitive decline and may even encounter early onset of dementia, according to a I conducted with my doctoral student <a href="https://sites.google.com/binghamton.edu/alan-adelman/home">Alan Adelman</a>. To establish that finding, we examined the effects of a rural pension program China introduced in 2009 that provided people who participated with a stable income if they stopped working after the official retirement age of 60. We found that people who participated in the program and retired within one or two years experienced a cognitive decline equivalent to a drop in general intelligence of 1.7% relative to the general population. This drop is equivalent to about three IQ points and could make it harder for someone to <a href="https://doi.org/10.1017/S0033291700008412">adhere to a medication schedule</a> or <a href="https://doi.org/10.1111/j.1475-%205890.2007.00052.x">conduct financial planning</a>. The largest negative effect was in what is called “delayed recall,” which measures a person’s ability to remember something mentioned several minutes ago. Neurological research <a href="https://doi.org/10.1001/archneur.1991.00530150046016">links problems in this area to an early onset of dementia</a>. <h2>Why it matters</h2> Cognitive decline refers to when a person has trouble remembering, learning new things, concentrating or making decisions that affect their everyday life. Although some cognitive decline appears to be an inevitable byproduct of aging, faster decline can have profound adverse consequences on one’s life. Better understanding of the causes of this has powerful financial consequences. Cognitive skills – the mental processes of gathering and processing information to solve problems, adapt to situations and learn from experiences – are crucial for decision-making. They influence an individual’s ability to process information and <a href="https://www.jstor.org/stable/1818642">are connected to higher earnings</a> and a <a href="https://www.doi.org/10.1257/jep.25.1.159">better quality of life</a>. Retiring early and working less or not at all can generate large benefits, such as reduced stress, better diets and more sleep. But as we found, it also has unintended adverse effects, like fewer social activities and less time spent challenging the mind, that far outweighed the positives. While retirement schemes like the 401(k) and similar programs in other countries <a href="https://www.doi.org/10.1023/B:PUCH.0000035859.20258.e0">are typically introduced to ensure the welfare of aging adults</a>, our research suggests they need to be designed carefully to avoid unintended and significant adverse consequences. When people consider retirement, they should weigh the benefits with the significant downsides of a sudden lack of mental activity. A good way to ameliorate these effects is to stay engaged in social activities and continue to use your brains in the same way you did when you were working. In short, we show that if you rest, you rust. <h2>What still isn’t known</h2> Because we are using data and a program in China, the mechanisms of how retirement induces cognitive decline could be context-specific and may not necessarily apply to people in other countries. For example, cultural differences or other policies that can provide support to individuals in old age can buffer some of the negative effects that we see in rural China due to the increase in social isolation and reduced mental activities. Therefore, we can not definitively say that the findings will extrapolate to other countries. We are looking for data from other countries’ retirement programs, such as India’s, to see if the effects are similar or how they are different. <h2>How I do my research</h2> A big focus of the <a href="https://scholar.harvard.edu/pnikolov/my-research-group-1">economics research lab</a> I run is to <a href="http://www.nber.org/%7Enikolovp/research.html">better understand</a> the causes and consequences of changes in what economists call <a href="https://www.britannica.com/topic/human-capital">“human capital”</a> – especially cognitive skills – in the context of developing countries. Our lab’s mission is to generate research to inform economic policies and empower individuals in low-income countries to rise out of poverty. One of the main ways we do this is through the use of randomized controlled trials to measure the impact of a particular intervention, such as retiring early or access to microcredit, on education outcomes, productivity and health decisions. <a href="https://theconversation.com/profiles/plamen-v-nikolov-1112610">Plamen V Nikolov</a>, Assistant Professor of Economics, <a href="https://theconversation.com/institutions/binghamton-university-state-university-of-new-york-2252">Binghamton University, State University of New York</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Alongside packing and planning, many turn to online reviews to choose the perfect hotel, restaurant, or activity. These reviews, often shared enthusiastically or with a hint of frustration, play a key role in shaping our experiences. But what happens to these reviews once they are posted? Do businesses truly read them, and if so, do they make changes based on customer feedback? The short answer is yes, businesses do read reviews and often act on them. In fact, for many, it’s a crucial part of their <a href="https://www.sciencedirect.com/science/article/abs/pii/S004016252100384X">customer engagement strategy</a>. Reviews offer a treasure trove of insights, from customer satisfaction and service quality to product usability and pricing perceptions. But beyond the numbers and star ratings, reviews provide a story of the customer experience that can highlight strengths and reveal weaknesses. Businesses, particularly in competitive industries like hospitality, often have dedicated teams or <a href="https://broadly.com/blog/reputation-management-tools/">software tools</a> to monitor reviews across platforms like Tripadvisor, Google, and Yelp. These tools can aggregate reviews, analyse sentiments, and even benchmark against competitors. For example, a hotel chain may use these insights to identify common themes in guest feedback, such as complaints about check-in delays or praises for room cleanliness. By doing so, they can prioritise issues and respond effectively. However, reading reviews is just the beginning. The real value lies in how businesses respond to them, and whether they take actionable steps to address the feedback. In many cases, customer reviews have become catalysts for change. For instance, a recurring complaint about outdated decor might prompt a hotel to refurbish its rooms. Similarly, consistent praise for a friendly staff member can lead to rewards or recognition programmes, boosting employee morale and enhancing the overall guest experience. <a href="https://ieeexplore.ieee.org/document/10614398">Some businesses</a> go a step further by engaging directly with reviewers. This engagement can take various forms, from public responses thanking customers for their feedback to private messages addressing specific concerns. <a href="https://www.emerald.com/insight/content/doi/10.1108/ITP-09-2018-0415/full/html">Such interactions</a> not only show that a business values its customers, but also humanises the brand, fostering trust and loyalty. A well-handled response to a negative review can even turn a dissatisfied customer into a loyal advocate. <h2>The role of negative reviews</h2> Negative reviews, while often dreaded by businesses, are an essential component of the feedback process. They provide honest, often blunt insights into what went wrong and where improvements are needed. For instance, during the holiday season, a restaurant might receive complaints about long wait times or underwhelming festive menus. Instead of viewing these reviews as setbacks, savvy businesses see them as opportunities to refine their offerings and enhance customer satisfaction. In some cases, businesses have <a href="https://ieeexplore.ieee.org/document/10614398">used negative reviews</a> as a springboard for innovation. A restaurant receiving feedback about limited vegetarian options might introduce new menu items, attracting a broader clientele and boosting sales. Similarly, a hotel criticised for lack of amenities might invest in additional facilities, improving its appeal and competitiveness. As technology evolves, the landscape of customer reviews and business responses is also changing. The rise of artificial intelligence and machine learning that uses algorithms has made it easier for businesses to analyse vast amounts of feedback and identify trends quickly. This capability allows for more proactive responses, with businesses anticipating issues before they become widespread problems. Moreover, the increasing use of video and photo reviews adds a new dimension to customer feedback. <a href="https://www.emerald.com/insight/content/doi/10.1108/JPBM-01-2019-2194/full/html?casa_token=adZDhhc3f0IAAAAA:7jPn1_y31gfB4BjJjLdl8QnnFixO3XCEOKbtemd0N2vhh_UCEHa1vjisRj3X3K1iw7UIRL1yylJGN6CCqPbW1Bs4CoSto1x0M1ntb_RtD7z-ZXHzj7Q">Visual reviews</a> can provide a more vivid portrayal of experiences, from showcasing a beautifully plated dish to highlighting a less-than-sparkling pool. Businesses are adapting to this trend by incorporating user-generated content into their marketing strategies, showcasing real-life customer experiences to attract new clients. However, the rise of fake reviews is a growing concern. In 2023, the popular travel website Tripadvisor <a href="https://www.tripadvisor.com/TransparencyReport2023#group-section-Fake-Reviews-HZjJZOxSZ4">saw an overwhelming influx</a> of user-generated content, with over 30 million reviews, however, amid this vast pool of feedback, 1.3 million reviews were flagged as fraudulent and subsequently removed. In the end, customer reviews are not just fleeting opinions left in the digital atmosphere. They are valuable conversations between businesses and their customers. For businesses, reviews offer an opportunity to understand their clients’ needs, address concerns, and celebrate successes. That is why businesses like <a href="https://www.aboutamazon.com/news/policy-news-views/how-ai-spots-fake-reviews-amazon">Amazon are using AI</a> to manage the reviews. By reading, responding, and, most importantly, acting on reviews, businesses can foster a loyal customer base and continually improve their offerings. So, the next time you leave a review, remember that someone is listening, and your words may just be the catalyst for positive change.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/236194/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/mina-tajvidi-1192090">Mina Tajvidi</a>, Lecturer in Digital Marketing, <a href="https://theconversation.com/institutions/queen-mary-university-of-london-1745">Queen Mary University of London</a>; <a href="https://theconversation.com/profiles/nick-hajli-1426223">Nick Hajli</a>, AI Strategist and Professor of Digital Strategy, <a href="https://theconversation.com/institutions/loughborough-university-1336">Loughborough University</a>, and <a href="https://theconversation.com/profiles/tahir-m-nisar-1050021">Tahir M.

Travel Trouble

MSG is back. Is the idea it’s bad for us just a myth or food science?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/evangeline-mantzioris-153250">Evangeline Mantzioris</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> MSG is making a comeback. The internet’s favourite cucumber salad recipe includes fish sauce, cucumber, garlic and – as the video’s creator Logan tells us with a generous sprinkle from the bag – “MSG, obviously”. But for many of us, it’s not obvious. Do you have a vague sense MSG is unhealthy but you’re not sure why? Here is the science behind monosodium glutamate, how it got a bad rap, and whether you should add it to your cooking. <h2>What is MSG?</h2> Monosodium glutamate (MSG) is a sodium salt of glutamic acid, one of the amino acids that make up proteins. It occurs naturally in <a href="https://www.tandfonline.com/doi/full/10.1080/10942912.2017.1295260#d1e167">foods</a> such as mature cheeses, fish, beef, mushrooms, tomatoes, onion and garlic. It provides their savoury and “meaty” flavour, known as <a href="https://www.sciencedirect.com/science/article/pii/S0022316622140186">umami</a>. MSG has been used to season food for <a href="https://wjpsonline.com/index.php/wjps/article/view/effects-monosodium-glutamate-human-health-review">more than 100 years</a>. Traditionally it <a href="https://pubs.acs.org/doi/epdf/10.1021/ed081p347?ref=article_openPDF">was extracted</a> from seaweed broth, but now it’s made by fermenting starch in sugar beets, sugar cane and molasses. Today it’s widely used as a flavour enhancer in many dishes and pre-packaged goods, including soups, condiments and processed meats. There is no chemical difference between the MSG found in food and the additive. <h2>Is it safe?</h2> For most people, yes. MSG is a safe and authorised additive, according to the Australian agency that regulates food. This corresponds with food standards in the <a href="https://www.fda.gov/food/food-additives-petitions/questions-and-answers-monosodium-glutamate-msg">United States</a>, <a href="https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX%3A02008R1333-20201223#tocId3">European Union and United Kingdom</a>. Two major <a href="https://www.foodstandards.gov.au/sites/default/files/consumer/additives/msg/Documents/MSG%20Technical%20Report.pdf">safety reviews</a> have been conducted: one in 1987 by a United Nations expert committee and another 1995 by the Federation of American Societies for Experimental Biology. Both concluded MSG was safe for the general population. In 2017 the <a href="https://www.efsa.europa.eu/en/efsajournal/pub/4910">European Food Safety Authority</a> updated its stance and set a recommended limit based on body weight, aimed to prevent headaches and increased blood pressure. That limit is still higher than most people consume. The authority says an 80kg person should not have more than 2.4g of added MSG per day. <a href="https://www.nature.com/articles/1602526">For reference</a>, Europeans average less than a gram per day (0.3-1 gram), while in Asia intake is somewhere between 1.2-1.7 grams a day. Food Standards Australia New Zealand says the European update does not raise any new safety concerns not already assessed. <h2>Isn’t it bad for me?</h2> Despite the evidence, the idea MSG is dangerous persists. Its notorious reputation can be traced back to a <a href="https://news.colgate.edu/magazine/2019/02/06/the-strange-case-of-dr-ho-man-kwok/">hoax letter</a> published in the <a href="https://www.nejm.org/doi/full/10.1056/NEJM196805162782014">New England Journal of Medicine</a> in 1968. A doctor claiming to have experienced palpitations, numbness and fatigue after eating at a Chinese restaurant suggested MSG could be to blame. With a follow-up article in the <a href="https://www.nytimes.com/1968/05/19/archives/-chinese-restaurant-syndrome-puzzles-doctors.html">New York Times</a>, the idea of “Chinese Restaurant Syndrome” took off. Eating MSG was associated with a range of symptoms, including headache, hives, throat swelling, itching and belly pain. However an <a href="https://www.sciencedirect.com/science/article/pii/027869159390012N?via%3Dihub">early randomised control trial</a> showed no difference in these symptoms between people who were given MSG versus a placebo. This has since been confirmed in a <a href="https://ift.onlinelibrary.wiley.com/doi/full/10.1111/1541-4337.12448">review of many studies</a>. <h2>Can MSG cause reactions?</h2> A very small percentage of people may have hypersensitivities to MSG. The reported reaction is now known as MSG symptom complex, rather than so-called Chinese restaurant syndrome, with its <a href="https://www.jandonline.org/article/S2212-2672(21)00068-X/abstract#:%7E:text=A%20New%20York%20Times%20piece,connecting%20MSG%20to%20health%20outcomes.">problematic</a> racial connotations. Symptoms are usually mild, short-term and don’t need treatment. <a href="https://www.sciencedirect.com/science/article/pii/S0091674999703714">One study</a> looked at 100 people with asthma, 30 of whom believed they had hypersensitivities to MSG. However when participants were blinded to whether they were consuming MSG, not one reported a reaction. If you believe you do react to added MSG, it’s relatively easy to avoid. In Australia, it is <a href="https://www.foodstandards.gov.au/consumer/additives/msg">listed</a> in ingredients as either monosodium glutamate or flavour enhancer 621. <h2>Is it better than table salt?</h2> Using MSG instead of regular salt may help <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6893472/">reduce</a> your overall sodium intake, as MSG <a href="https://www.medicalnewstoday.com/articles/msg-what-the-science-says-about-its-safety#Uses-of-MSG">contains</a> about one third the amount of sodium. <a href="https://pubmed.ncbi.nlm.nih.gov/21372742/">One study</a> found people who ate soup seasoned with MSG rather than salt actually liked it more. They still found it salty to taste, but their sodium intake was reduced by 18%. MSG still contains sodium, so high use is associated with increased <a href="https://pubmed.ncbi.nlm.nih.gov/21372742/">blood pressure</a>. If you’re using MSG as a substitute and you have high blood pressure, you should closely monitor it (just as you would with other salt products). <h2>Should I use MSG in my cooking?</h2> If you want to – yes. Unless you are one of the rare people with hypersensitivities, enhancing the flavour of your dish with a sprinkle of MSG will not cause any health problems. It could even help reduce how much salt you use. If you’re <a href="https://www.tandfonline.com/doi/full/10.1080/25765299.2020.1807084#d1e199">vegetarian or vegan</a>, cooking with MSG could help add the umami flavour you may miss from animal products such as meat, fish sauce and cheese. But buying foods with added MSG? Be aware, many of them will also be <a href="https://www.cambridge.org/core/journals/public-health-nutrition/article/un-decade-of-nutrition-the-nova-food-classification-and-the-trouble-with-ultraprocessing/2A9776922A28F8F757BDA32C3266AC2A">ultra-processed</a> and it’s that – not the MSG – that’s associated with poor physical and mental <a href="https://www.mdpi.com/2072-6643/14/1/174">health outcomes</a>.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/237871/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/evangeline-mantzioris-153250">Evangeline Mantzioris</a>, Program Director of Nutrition and Food Sciences, Accredited Practising Dietitian, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"Laughably bad": New sculpture of Queen Elizabeth and Prince Philip divides opinion

A newly unveiled bronze sculpture of the late Queen Elizabeth II and Prince Philip has received somewhat mixed reviews from the public, with many criticising the piece for looking "nothing like" them. The artwork was unveiled at Antrim Castle Gardens in Northern Ireland on Friday, and was commissioned by Antrim and Newtownabbey Borough Council, which said the piece “captures Her Majesty in a dignified pose, reflecting her grace, steadfastness and lifelong dedication to public service”. It also depicts two of her famous corgis at her feet and her husband, Philip standing behind her with his hands behind his back. While the local council told CNN that the bronze statue of the Queen "has been warmly received by most who have seen it in person," many have ridiculed the statue for looking nothing like them. One user wrote on X that it was "laughably bad", adding: "It doesn't even look an iota like her, does it? Am I blind, or is that just nothing like the Queen? Surely they pay a fortune for these commissioned pieces - is there no requirement that there actually be a likeness?" <blockquote class="twitter-tweet"> It doesn't even look an iota like her, does it? Am I blind, or is that just nothing like the Queen? Surely they pay a fortune for these commissioned pieces - is there no requirement that there actually be a likeness? Why is everything so shit, now? — Dr Dani Sulikowski (@DrDaniS) <a href="https://twitter.com/DrDaniS/status/1832347891433927015?ref_src=twsrc%5Etfw">September 7, 2024</a></blockquote> Another user on X wrote: “It is awful...It looks nothing like the Queen or the Prince.. Terrible..Dreadful..Melt it down and start again”. One person commented on the council's announcement of the artwork that while it was "beautiful" the statue didn't "look like our late queen or represent how she always dressed". "Even the corgi is confused," another user wrote. “Would you know this was the late Queen if I didn't tell you?" another wrote on X. Following the wave of criticism, the council acknowledged that at "art can sometimes spark diverse opinions" but said that it "was particularly pleased with how the (Elizabeth) sculpture complements its surroundings, standing adjacent to the statue of Prince Philip, Duke of Edinburgh, and accompanied by two lovingly crafted corgis."

Is white rice bad for me? Can I make it lower GI or healthier?

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/emma-beckett-22673">Emma Beckett</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> Rice is a <a href="http://www.ipni.net/publication/bci.nsf/0/42A2EA40E95CBD1385257BBA006531E9/$FILE/Better%20Crops%20International%202002-3%20p03.pdf">culinary staple</a> in Australia and around the world. It might seem like a given that brown rice is healthier than white and official <a href="https://www.eatforhealth.gov.au/eating-well/healthy-recipes/recipe-modification-tips">public health resources</a> often recommend brown rice instead of white as a “healthy swap”. But <a href="https://pubmed.ncbi.nlm.nih.gov/34441728/">Australians definitely prefer white rice</a> over brown. So, what’s the difference, and what do we need to know when choosing rice? <h2>What makes rice white or brown?</h2> Rice “grains” are technically seeds. A complete, whole rice seed is called a “paddy”, which has <a href="https://www.fao.org/4/t0567e/t0567e07.htm">multiple parts</a>: <ol> <li>the “hull” is the hard outer layer which protects the seed</li> <li>the “bran”, which is a softer protective layer containing the seed coat</li> <li>the “germ” or the embryo, which is the part of the seed that would develop into a new plant if was germinated</li> <li>the “endosperm”, which makes up most of the seed and is essentially the store of nutrients that feeds the developing plant as a seed grows into a plant.</li> </ol> Rice needs to be <a href="https://www.tandfonline.com/doi/pdf/10.1080/87559128509540778">processed</a> for humans to eat it. Along with cleaning and drying, the hard hulls are removed since we can’t digest them. This is how <a href="https://ift.onlinelibrary.wiley.com/doi/abs/10.1111/1541-4337.12449">brown rice is made</a>, with the other three parts of the rice remaining intact. This means brown rice is regarded as a “wholegrain”. White rice, however, is a “refined” grain, as it is <a href="https://ift.onlinelibrary.wiley.com/doi/abs/10.1111/1541-4337.12449">further polished</a> to remove the bran and germ, leaving just the endosperm. This is a mechanical and not a chemical process. <h2>What’s the difference, nutritionally?</h2> Keeping the bran and the germ means <a href="https://onlinelibrary.wiley.com/doi/abs/10.1002/cche.10322">brown rice has more</a> magnesium, phosphorus, potassium B vitamins (niacin, folate, riboflavin and pyridoxine), iron, zinc and fibre. The germ and the bran also contain more bioactives (compounds in foods that aren’t essential nutrients but have health benefits), like <a href="https://www.mdpi.com/1420-3049/28/2/532#:%7E:text=Brown%20rice%20(BR)%20is%20obtained,and%20phenolic%20compounds%20%5B3%5D.">oryzanols and phenolic compounds</a> which have antioxidant effects. But that doesn’t mean white rice is just empty calories. It <a href="https://www.glnc.org.au/wp-content/uploads/2011/04/GLNC_Rice-factsheet_WEB.pdf">still contains</a> vitamins, minerals and some fibre, and is low in fat and salt, and is naturally gluten-free. White and brown rice actually have <a href="https://ift.onlinelibrary.wiley.com/doi/abs/10.1111/1541-4337.12449">similar</a> amounts of calories (or kilojoules) and total carbohydrates. There are studies that show eating more white rice is linked to <a href="https://diabetesjournals.org/care/article/43/11/2625/35820/A-Global-Perspective-on-White-Rice-Consumption-and">a higher risk</a> of type 2 diabetes. But it is difficult to know if this is down to the rice itself, or other related factors such as socioeconomic variables or other dietary patterns. <h2>What about the glycaemic index?</h2> The higher fibre means brown rice has a <a href="https://www.sciencedirect.com/science/article/pii/S0002916523314862">lower glycaemic index</a> (GI), meaning it raises blood sugar levels more slowly. But this is highly variable between different rices within the white and brown categories. The <a href="https://www.betterhealth.vic.gov.au/health/healthyliving/carbohydrates-and-the-glycaemic-index#:%7E:text=The%20glycaemic%20index%20(GI)%20is,simple'%20or%20'complex'.">GI system</a> uses low (less than 55), medium (55–70) and high (above 70) categories. <a href="https://glycemicindex.com/gi-search/?food_name=rice&product_category=&country=&gi=&gi_filter=&serving_size_(g)=&serving_size_(g)_filter=&carbs_per_serve_(g)=&carbs_per_serve_(g)_filter=&gl=&gl_filter=">Brown rices</a> fall into the low and medium categories. <a href="https://glycemicindex.com/gi-search/?food_name=rice&product_category=&country=&gi=&gi_filter=&serving_size_(g)=&serving_size_(g)_filter=&carbs_per_serve_(g)=&carbs_per_serve_(g)_filter=&gl=&gl_filter=">White rices</a> fall in the medium and high. There are specific <a href="https://www.gisymbol.com/low-gi-products/sunrice-doongara-low-gi-white-clever-rice-1kg/">low-GI types available</a> for both white and brown types. You can also lower the GI of rice by <a href="https://pubs.acs.org/doi/abs/10.1021/jf503203r">heating and then cooling it</a>. This process converts some of the “available carbohydrates” into “resistant starch”, which then functions like dietary fibre. <h2>Are there any benefits to white rice?</h2> The <a href="https://www.realsimple.com/brown-rice-vs-white-rice-8417468#:%7E:text=The%20eating%20experience%20between%20these,chewier%20texture%20and%20nuttier%20flavor.">taste and textural qualities</a> of white and brown rices differ. White rice tends to have a softer texture and more mild or neutral flavour. Brown rice has a chewier texture and nuttier flavour. So, while you can technically substitute brown rice into most recipes, the experience will be different. Or other ingredients may need to be added or changed to create the desired texture. Removing more of the outer layers may also reduce the levels of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10375490/">contaminants</a> such as pesticides. <h2>We don’t just eat rice</h2> Comparing white and brown rice seems like an easy way to boost nutritional value. But just because one food (brown rice) is more nutrient-dense doesn’t make the other food (white rice) “bad”. Ultimately, it’s not often that we eat just rice, so we don’t need the rice we choose to be the perfect one. Rice is typically the staple base of a more complex dish. So, it’s probably more important to think about what we eat with rice. Adding vegetables and lean proteins to rice-based dishes can easily add the micronutrients, bioactives and fibre that white rice is comparatively lacking, and this can likely do more to contribute to diet quality than eating brown rice instead.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/236767/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/emma-beckett-22673">Emma Beckett</a>, Adjunct Senior Lecturer, Nutrition, Dietetics & Food Innovation - School of Health Sciences, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

People who are bad with numbers often find it harder to make ends meet – even if they are not poor

That’s according to <a href="https://doi.org/10.1371/journal.pone.0260378">our analyses</a> of the <a href="https://wrp.lrfoundation.org.uk/explore-the-poll">Lloyd’s Register Foundation World Risk Poll</a>. In this World Risk Poll, people from 141 countries were asked if 10% was bigger than, smaller than or the same as 1 out of 10. Participants were said to be bad with numbers if they did not provide the correct answer – which is that 10% is the same as 1 out of 10. <a href="https://doi.org/10.1371/journal.pone.0260378">Our analyses</a> found that people who answered incorrectly are often among the poorest in their country. Prior studies in the <a href="https://doi.org/10.1111/j.1468-0297.2010.02394.x">United States</a>, <a href="https://doi.org/10.1111/j.1475-5890.2007.00052.x">United Kingdom</a>, <a href="https://doi.org/10.1016/j.joep.2016.02.011">the Netherlands</a> and <a href="https://doi.org/10.1111/joca.12294">Peru</a> had also found that people who are bad with numbers are financially worse off. But <a href="https://doi.org/10.1371/journal.pone.0260378">our analyses of the World Risk Poll</a> further showed that people who are bad with numbers find it harder to make ends meet, even if they are not poor. When we say that they found it harder to make ends meet, we mean that they reported on the poll that they found it difficult or very difficult to live on their current income, as opposed to living comfortably or getting by on their current income. <a href="https://doi.org/10.1371/journal.pone.0260378">Our analyses</a> also indicate that staying in school longer is related to better number ability. People with a high school degree tend to be better with numbers than people without a high school degree. And college graduates do even better. But even among college graduates there are people who are bad with numbers – and they struggle more financially. <iframe id="yOIiX" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/yOIiX/3/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe> Of course, being good with numbers is not going to help you stretch your budget if you are very poor. <a href="https://doi.org/10.1371/journal.pone.0260378">We found</a> that the relationship between number ability and struggling to make ends meet holds across the world, except in low-income countries like Ethiopia, Somalia and Rwanda. <iframe id="RejA1" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/RejA1/8/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe> <h2>Why it matters</h2> The ability to understand and use numbers is also called <a href="http://doi.org/10.1093/oso/9780190861094.001.0001">numeracy</a>. Numeracy is <a href="https://doi.org/10.1787/1f029d8f-en">central to modern adult life</a> because numbers are everywhere. A lot of well-paying jobs involve working with numbers. People who are bad with numbers often perform worse in these jobs, including <a href="https://doi.org/10.1111/ecin.12873">banking</a>. It can therefore be hard for people who are bad with numbers to <a href="http://www.doi.org/10.1108/00400919710164125">find employment and progress in their jobs</a>. People who are bad with numbers are less likely <a href="https://www.pnas.org/content/116/39/19386.short">to make good financial decisions</a>. Individuals who can’t compute how interest compounds over time <a href="https://doi.org/10.1111/j.1540-6261.2009.01518.x">save the least and borrow the most</a>. People with poor numerical skills are also more likely <a href="https://doi.org/10.1037/0022-3514.41.3.586">to take on high-cost debt</a>. If you’re bad with numbers, it is hard to <a href="https://doi.org/10.1017/S1474747215000232">recognize</a> that paying the US$30 minimum payment on a credit card with a $3,000 balance and an annual percentage rate of 12% means it will never be paid off. <h2>What still isn’t known</h2> It is clear that people who are bad with numbers also tend to struggle financially. But we still need to explore whether teaching people math will help them to avoid financial problems. <h2>What’s next</h2> In her book “<a href="http://doi.org/10.1093/oso/9780190861094.001.0001">Innumeracy in the Wild</a>,” Ellen Peters, director of the Center for Science Communication Research at the University of Oregon, suggests that it is important for students to take math classes. American high school students who had to <a href="https://doi.org/10.3368/jhr.51.3.0113-5410R1">take more math courses</a> than were previously required had better financial outcomes later in life, such as avoiding bankruptcy and foreclosures. Successfully teaching numeracy also means helping students gain confidence in using numbers. People with <a href="https://doi.org/10.1073/pnas.1903126116">low numerical confidence</a> experience bad financial outcomes, such as a foreclosure notice, independent of their numeric ability. This is because they may not even try to take on complex financial decisions. Numerical confidence can be boosted in different ways. Among American <a href="https://doi.org/10.1037/0022-3514.41.3.586">elementary school children</a> who were bad with numbers, setting achievable goals led to better numerical confidence and performance. Among American <a href="https://doi.org/10.1371/journal.pone.0180674">undergraduate students</a>, a writing exercise that affirmed their positive values improved their numerical confidence and performance. Other important next steps are to find out whether training in numeracy can also be provided to adults, and whether training in numeracy improves the financial outcomes of people who do not live in high-income countries.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/172272/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/wandi-bruine-de-bruin-275600">Wändi Bruine de Bruin</a>, Professor of Public Policy, Psychology and Behavioral Science, USC Sol Price School of Public Policy, <a href="https://theconversation.com/institutions/usc-dornsife-college-of-letters-arts-and-sciences-2669">USC Dornsife College of Letters, Arts and Sciences</a> and <a href="https://theconversation.com/profiles/paul-slovic-359838">Paul Slovic</a>, Professor of Psychology, <a href="https://theconversation.com/institutions/university-of-oregon-811">University of Oregon</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"Bad news": Jimmy Barnes reveals shocking health update

Jimmy Barnes has been taken to hospital after complaining of "unbearable pain" while on the New Zealand leg of his tour. The Aussie rock legend took to Instagram to tell his fans that he would be out of action for six weeks after experiencing pain in his hip that requires surgical intervention. "I’ve got some bad news unfortunately," he started the post. "I had a twinge in my hip when I was leaving Dunedin on Thursday morning and by late last night the pain was unbearable so I went off to hospital." "The doctors have recommended a remedial medical procedure ASAP followed by some physio to address the issue. These doctors don’t muck around! Providing all goes to plan, I’m expected to make a full recovery in six weeks." The 68-year-old then clarified that because of the upcoming surgery, his August and September shows on his Hell of a Time tour would be impacted. "Ticket holders will be contacted with further info in the coming days once we have new plans in place," he said. "As you know, I hate to let anyone down, but I’m also never going to compromise the quality of my gigs. I apologise for the inconvenience this will cause everyone – I HATE moving shows! - but thank you for understanding." Just hours after his post, Jimmy's wife Jane took to his social media accounts to tell his fans that he was out the ICU and "recovering well" while he awaits the procedure. <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-permalink="https://www.instagram.com/p/C-PaHMCT78j/?utm_source=ig_embed&utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"> </div> </div> </div> <div style="padding: 19% 0;"> </div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"> </div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <div style="padding: 12.5% 0;"> </div> <div style="display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;"> <div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);"> </div> <div style="background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;"> </div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);"> </div> </div> <div style="margin-left: 8px;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;"> </div> <div style="width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);"> </div> </div> <div style="margin-left: auto;"> <div style="width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);"> </div> <div style="background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);"> </div> <div style="width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);"> </div> </div> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;"> </div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/p/C-PaHMCT78j/?utm_source=ig_embed&utm_campaign=loading" target="_blank" rel="noopener">A post shared by Jimmy Barnes (@jimmybarnesofficial)</a> </div> </blockquote> "Jimmy is out of ICU and recovering well.

Poor sleep is really bad for your health. But we found exercise can offset some of these harms

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/bo-huei-huang-1243280">Bo-Huei Huang</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> and <a href="https://theconversation.com/profiles/emmanuel-stamatakis-161783">Emmanuel Stamatakis</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Despite the well-known links between poor sleep and poorer health, getting enough good quality sleep has become a luxury in modern society. Many of us struggle to improve our sleep, while amid the COVID pandemic and recurring lock-downs, <a href="https://theconversation.com/were-sleeping-more-in-lockdown-but-the-quality-is-worse-155797">our sleep has deteriorated</a>. But <a href="https://doi.org/10.1136/bjsports-2021-104046">our new study</a>, published today in the British Journal of Sports Medicine, bears some encouraging news. We found doing enough physical activity (including exercise such as running or going to the gym) may counter some of the adverse health effects of unhealthy sleep patterns. Let us explain. <h2>Does poor sleep really harm our health?</h2> Unhealthy sleep patterns include: <ul> <li> not sleeping for long enough (less than seven hours per night for adults) </li> <li> sleeping for too long (more than nine hours per night for adults) </li> <li> snoring </li> <li> insomnia </li> <li> being a night owl, also known as “late chronotype”. This is people who naturally feel most awake and motivated in the evening, and are sluggish in the morning. </li> </ul> They are <a href="https://doi.org/10/ggjqrt">all associated</a> with poorer health. Recent research shows poor sleep may: <ul> <li> cause <a href="https://doi.org/10.1038/s41577-019-0190-z">inflammation</a> </li> <li> impair the metabolism of glucose (also known as blood sugar) and reduce the number of calories burned, thereby increasing the risk of <a href="https://theconversation.com/why-sleep-is-so-important-for-losing-weight-145058">obesity</a> </li> <li> increase the risk of <a href="https://doi.org/10/gg6x87">heart disease</a> and <a href="https://doi.org/10/ggnw5h">premature death</a>. </li> </ul> However, very few studies have examined how sleep and physical activity interact and impact our health. We set out to answer the question: if I have poor sleep but I do quite a lot of physical activity, can that offset some of the harms of my poor sleep in the long-term? Or would this not make any difference? <h2>What did we do?</h2> We analysed the information provided by 380,055 middle-aged adults in the UK Biobank study, recruited between 2006 and 2010. Participants reported their level of physical activity and five aspects of their sleep. We grouped people based on their sleep behaviour into healthy, intermediate or poor. We categorised people’s level of physical activity based on <a href="https://bjsm.bmj.com/content/54/24/1451">the World Health Organization (WHO) guidelines</a>. People who met the upper bounds of the guidelines did 300 minutes of moderate intensity physical activity a week, or 150 minutes of vigorous exercise, or a combination of both. Those who met the lower bound did 150 minutes of moderate intensity exercise a week, or 75 minutes of vigorous exercise, or a combination. Moderate intensity physical activity usually makes you slightly out of breath if sustained for a few minutes and includes brisk walking or cycling at a leisurely pace. Vigorous exercise usually makes you breath hard and can include running, swimming, and playing sports like tennis, netball, soccer or footy. <figure class="align-center "><img src="https://images.theconversation.com/files/408096/original/file-20210624-15-1qfe1ay.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/408096/original/file-20210624-15-1qfe1ay.png?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=409&fit=crop&dpr=1 600w, https://images.theconversation.com/files/408096/original/file-20210624-15-1qfe1ay.png?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=409&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/408096/original/file-20210624-15-1qfe1ay.png?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=409&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/408096/original/file-20210624-15-1qfe1ay.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=515&fit=crop&dpr=1 754w, https://images.theconversation.com/files/408096/original/file-20210624-15-1qfe1ay.png?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=515&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/408096/original/file-20210624-15-1qfe1ay.png?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=515&fit=crop&dpr=3 2262w" alt="" /><figcaption>Doing at least 150 minutes of moderate intensity physical activity a week, or 75 minutes of vigorous exercise, can offset some of the health harms of poor sleep. <a class="source" href="https://apps.who.int/iris/bitstream/handle/10665/336656/9789240015128-eng.pdf?sequence=1&isAllowed=y">World Health Organization, CC BY-NC-SA 3.0 IGO</a></figcaption></figure> <h2>What did we find?</h2> We followed up with the participants after 11 years. By May 2020, 15,503 participants had died, of which 4,095 died from heart disease and 9,064 died from cancer. <a href="https://doi.org/10.1136/bjsports-2021-104046">We found</a> that, compared to healthy sleepers, people with poor sleep had a 23% higher risk of premature death, a 39% higher risk of dying from heart disease, and a 13% higher risk of dying from cancer. We then compared the data of people who slept well with those who slept poorly, and how much they exercised. We found people who had the highest risk of dying from heart disease and cancer were those who had poor sleep and didn’t meet the WHO physical activity guidelines. On the other hand, those who had poor sleep but did enough physical activity to meet the WHO guidelines didn’t have as high a risk of dying from heart disease or cancer, compared to those who slept poorly and didn’t meet the physical activity guidelines. For example, let’s look at the risk of dying from cancer. Those who had poor sleep and did no physical activity had a 45% higher risk of dying from cancer compared to those who had healthy sleep and exercised a lot. But among those who met the physical activity guidelines, despite poor sleep, they didn’t really have a higher risk of dying from cancer any more. We found physical activity levels which met at least the bottom threshold of the WHO guidelines could reduce or eliminate some of the health harms of poor sleep. So people who did at least 150 minutes of moderate intensity or 75 minutes of vigorous intensity exercise per week were to some extent protected against the detrimental health effects of poor sleep. Those who had both poor sleep and did no moderate-to-vigorous intensity physical activity had the highest risks of premature death. Our study wasn’t designed to find out how and why physical activity may counteract some of the bad physiological impacts of poor sleep. But other research provides theories. For example, adequate physical activity may <a href="https://doi.org/10.1249/MSS.0000000000001179">reduce inflammation, help maintain a healthy glucose metabolism</a>, and <a href="https://doi.org/10.1016/j.pcad.2018.07.014">increase the number of calories burned</a>. It’s important to note our study was what’s called an “observational study”. It shows an association between adequate physical activity and reduced harms from poor sleep, but we must be careful in interpreting causation. It can’t conclusively say adequate physical activity causes the reduction of harms from poor sleep, though there’s strong evidence for an association in the right direction. Our study offers a hopeful message, that even if you haven’t been able to improve your sleep, you can still offset some of the health harms by doing enough exercise. <a href="https://www.sciencedirect.com/science/article/abs/pii/S009174352030339X">Our previous research</a> has also shown physical activity may help improve poor sleep patterns, which are a serious health problem across the world. In addition to combating some of the negative outcomes of poor sleep, physical activity can also provide many other health benefits and extend our lives. For example, a 2019 study found people who met WHO’s physical activity target above <a href="https://doi.org/10.1186/s12916-019-1339-0">lived three years longer on average</a> than those who didn’t. During lockdowns, access to parks, gyms, and swimming pools might be limited in many places. But there are still many ways to <a href="https://www.euro.who.int/en/health-topics/health-emergencies/coronavirus-covid-19/publications-and-technical-guidance/noncommunicable-diseases/stay-physically-active-during-self-quarantine">to stay fit and active at home during the coronavirus</a>.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/163270/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/bo-huei-huang-1243280">Bo-Huei Huang</a>, PhD candidate, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> and <a href="https://theconversation.com/profiles/emmanuel-stamatakis-161783">Emmanuel Stamatakis</a>, Professor of Physical Activity, Lifestyle, and Population Health, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Take my (bad) breath away – causes of halitosis and how to check whether you have it

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/dan-baumgardt-1451396">Dan Baumgardt</a>, <a href="https://theconversation.com/institutions/university-of-bristol-1211">University of Bristol</a> In Greek mythology, the many-headed beast <a href="https://mythopedia.com/topics/hydra">Hydra</a> had such severe <a href="https://patient.info/oral-dental-care/bad-breath-halitosis">halitosis</a> that the stench of its breath was deadly to anyone who smelled it. Thankfully, our morning breath might not be that pungent – although eating <a href="https://www.healthline.com/health/get-rid-of-garlic-onion-breath">onions or garlic</a> can put some people in competition with the Hydra. Halitosis has many causes (aside from poor oral hygiene) and can indicate problems with the gut, the sinuses and even the bloodstream. In fact, breath samples can even be tested to make formal diagnoses of health conditions. One condition that can affect the smell of breath is <a href="https://www.diabetes.org.uk/">diabetes mellitus</a>. This is a metabolic disorder where sugar (glucose) is unable to access the body’s cells where it is needed to provide energy, and so rises in the bloodstream. In some instances, such as insufficient insulin dosing, or infection, the body’s response is to break down fats into compounds called ketones to act as a rapid form of fuel. This serious condition is called <a href="https://www.nhs.uk/conditions/diabetic-ketoacidosis/">diabetic ketoacidosis</a>. Ketones have a distinctive scent. <a href="https://www.gov.uk/government/publications/acetone-properties-and-incident-management/acetone-general-information">Acetone</a>, which is also an ingredient in some nail varnish removers, is one of these ketones and has the smell of pear drops. When ketones build up in the bloodstream they easily <a href="https://iopscience.iop.org/article/10.1088/0967-3334/32/8/N01/pdf">diffuse into the breath</a>, giving it a <a href="https://www.medicalnewstoday.com/articles/319683">fruity odour</a>. It’s not just diabetes that can trigger ketone production. <a href="https://pubmed.ncbi.nlm.nih.gov/36033148/">Some diets</a> are based on generating ketones from the breakdown of fats to promote weight loss. These methods, such as the <a href="https://www.healthline.com/nutrition/atkins-diet-101">Atkins diet</a>, force the body to convert fat into energy by restricting carbohydrates. <figure><iframe src="https://www.youtube.com/embed/5U8IDO1fHlU?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> Other diets based on the same principles include the <a href="https://patient.info/healthy-living/weight-loss-weight-reduction/52-diet">5:2</a> intermittent fasting diet. On this diet, followers restrict food intake on two days of the week to significantly reduce calorie consumption – and make the body produce ketones. These diets may help weight loss, but the side-effects can be grim. One of the most notorious side-effects is foul breath, although there are also anecdotal reports of <a href="https://www.forbes.com/sites/brucelee/2019/03/03/is-keto-crotch-really-a-side-effect-of-the-keto-diet/">“keto crotch”</a> where some followers of keto diets complain of strong genital odour. <h2>Bacteria and breath</h2> Another cause of bad breath is an <a href="https://iopscience.iop.org/article/10.1088/1752-7155/4/1/017003/pdf">overgrowth of bacteria</a> that produce foul smells. There are plenty of nooks and crannies in the mouth for bacteria to hide, grow and fester, especially the hard-to-clean areas – in between the teeth, and in and around the gums and tongue – or out-of-reach places, such as right at the back of the mouth and the throat. The throat acts as a passage for food, fluids and air. Some patients can develop a condition called <a href="https://www.entuk.org/patients/conditions/49/pharyngeal_pouch_surgery_new">pharyngeal pouch</a>. This is where a pocket forms at the back of the pharynx (the medical name for the throat) in which food and fluids can accumulate, ferment and give breath a pungent odour. Bacteria can also trigger infections in the mouth, like tonsillitis and tooth abscesses where tissues become inflamed, or develop purulence (production of pus). Pus is a collection of different dead cells, including bacteria, and it too can give off a putrid smell. Also, <a href="https://pubmed.ncbi.nlm.nih.gov/25234037/">sinusitis</a> – which is an infection of the air-filled cavities in the skull – can drip foul-smelling infected secretions into the throat, causing bad breath. <h2>Breath tests</h2> Doctors can test breath for bacteria to diagnose some health conditions. For example, <a href="https://pubmed.ncbi.nlm.nih.gov/28891138/">Helicobacter pylori</a>, bacteria that can irritate the gut and lead to the development of potentially dangerous ulcers, turns the compound urea into carbon dioxide. To test for H pylori, a <a href="https://www.nhs.uk/conditions/stomach-ulcer/diagnosis/">diagnostic breath test</a> is performed before and after dosing a patient with urea. If the patient exhales increased levels of carbon dioxide after being dosed with urea, then the test is positive. Breath can also be tested for an overgrowth of bacteria in the <a href="https://www.healthline.com/health/sibo">small intestine</a> (Sibo), which can lead to symptoms like abdominal pain and bloating. Sibo produces gases like hydrogen and methane that can also be detected with a breath test. If you’re worried about pongy breath and don’t have any medical issues, then you can <a href="https://www.healthline.com/health/dental-and-oral-health/how-to-smell-your-own-breath">test your own breath</a>. The age-old method is to lick the back of your wrist, let it dry and then have a sniff. You can also do the same with a tongue scraper, dental floss or a sample of breath exhaled into a cupped hand. <figure><iframe src="https://www.youtube.com/embed/ak5UEM8FK2s?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> Often, we can become used to the smell of our own breath. We might only notice when it becomes really bad, or when there are other symptoms, like a foul taste in the mouth. Or when someone plucks up the courage to finally tell you that you have a case of the breath pongs. Suppose someone has broken the news – what do you do now? <a href="https://www.nhs.uk/conditions/bad-breath/">Simple measures can work well</a>, including regular fluid intake – <a href="https://www.dentalhealth.org/bad-breath">dry mouth</a> can lead to bad breath so make sure you’re drinking enough water – and good oral hygiene. This involves brushing the teeth, tongue and flossing between your teeth to eliminate any bacterial hot spots, as well as regular checkups at the dentist. Mouthwash can be an effective temporary solution but there’s evidence that a <a href="https://theconversation.com/eating-leafy-greens-could-be-better-for-oral-health-than-using-mouthwash-221181#:%7E:text=But%20research%20has%20indicated%20that,alternative%20for%20treating%20oral%20disease.">diet rich in leafy greens</a> might be even better at countering bad breath. Smoking is another potential underlying <a href="https://www.healthline.com/health/how-to-get-rid-of-cigarette-breath#1-brush-teeth">cause of halitosis</a>. So if you want sweeter breath, pack in the cigarettes – yet another good reason to give up.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/231858/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/dan-baumgardt-1451396">Dan Baumgardt</a>, Senior Lecturer, School of Physiology, Pharmacology and Neuroscience, <a href="https://theconversation.com/institutions/university-of-bristol-1211">University of Bristol</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Not all ultra-processed foods are bad for your health, whatever you might have heard

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/gary-sacks-3957">Gary Sacks</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>; <a href="https://theconversation.com/profiles/kathryn-backholer-10739">Kathryn Backholer</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>; <a href="https://theconversation.com/profiles/kathryn-bradbury-1532662">Kathryn Bradbury</a>, <a href="https://theconversation.com/institutions/university-of-auckland-waipapa-taumata-rau-1305">University of Auckland, Waipapa Taumata Rau</a>, and <a href="https://theconversation.com/profiles/sally-mackay-1532685">Sally Mackay</a>, <a href="https://theconversation.com/institutions/university-of-auckland-waipapa-taumata-rau-1305">University of Auckland, Waipapa Taumata Rau</a> In recent years, there’s been <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11036430/">increasing</a> <a href="https://theconversation.com/ultra-processed-foods-heres-what-the-evidence-actually-says-about-them-220255#:%7E:text=Hype%20around%20ultra%2Dprocessed%20food,or%20worry%20about%20their%20health.">hype</a> about the potential health risks associated with so-called “ultra-processed” foods. But new evidence published <a href="https://www.bmj.com/content/385/bmj-2023-078476">this week</a> found not all “ultra-processed” foods are linked to poor health. That includes the mass-produced wholegrain bread you buy from the supermarket. While this newly published research and associated <a href="https://www.bmj.com/content/385/bmj.q793">editorial</a> are unlikely to end the wrangling about how best to define unhealthy foods and diets, it’s critical those debates don’t delay the implementation of policies that are likely to actually improve our diets. <h2>What are ultra-processed foods?</h2> <a href="https://pubmed.ncbi.nlm.nih.gov/30744710/">Ultra-processed foods</a> are industrially produced using a variety of processing techniques. They typically include ingredients that can’t be found in a home kitchen, such as preservatives, emulsifiers, sweeteners and/or artificial colours. Common examples of ultra-processed foods include packaged chips, flavoured yoghurts, soft drinks, sausages and mass-produced packaged wholegrain bread. In <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7719194/#CR13">many other countries</a>, ultra-processed foods make up a large proportion of what people eat. A <a href="https://pubmed.ncbi.nlm.nih.gov/31676952/">recent study</a> estimated they make up an average of 42% of total energy intake in Australia. <h2>How do ultra-processed foods affect our health?</h2> Previous <a href="https://pubmed.ncbi.nlm.nih.gov/33167080/">studies</a> have linked increased consumption of ultra-processed food with poorer health. High consumption of ultra-processed food, for example, has been associated with a <a href="https://pubmed.ncbi.nlm.nih.gov/38418082/">higher risk</a> of type 2 diabetes, and death from heart disease and stroke. Ultra-processed foods are typically high in energy, added sugars, salt and/or unhealthy fats. These have long been <a href="https://www.who.int/news-room/fact-sheets/detail/healthy-diet">recognised</a> as risk factors for a range of diseases. It has also been suggested that structural changes that happen to ultra-processed foods as part of the manufacturing process <a href="https://pubmed.ncbi.nlm.nih.gov/31105044/">may</a> lead you to eat more than you should. Potential explanations are that, due to the way they’re made, the foods are quicker to eat and more palatable. It’s also <a href="https://pubmed.ncbi.nlm.nih.gov/35952706/">possible</a> certain food additives may impair normal body functions, such as the way our cells reproduce. <h2>Is it harmful? It depends on the food’s nutrients</h2> The <a href="https://www.bmj.com/content/385/bmj-2023-078476">new paper</a> just published used 30 years of data from two large US cohort studies to evaluate the relationship between ultra-processed food consumption and long-term health. The study tried to disentangle the effects of the manufacturing process itself from the nutrient profile of foods. The study found a small increase in the risk of early death with higher ultra-processed food consumption. But importantly, the authors also looked at diet quality. They found that for people who had high quality diets (high in fruit, vegetables, wholegrains, as well as healthy fats, and low in sugary drinks, salt, and red and processed meat), there was no clear association between the amount of ultra-processed food they ate and risk of premature death. This suggests overall diet quality has a stronger influence on long-term health than ultra-processed food consumption. When the researchers analysed ultra-processed foods by sub-category, mass-produced wholegrain products, such as supermarket wholegrain breads and wholegrain breakfast cereals, were not associated with poorer health. This finding matches another recent <a href="https://pubmed.ncbi.nlm.nih.gov/38417577/">study</a> that suggests ultra-processed wholegrain foods are not a driver of poor health. The authors concluded, while there was some support for limiting consumption of certain types of ultra-processed food for long-term health, not all ultra-processed food products should be universally restricted. <h2>Should dietary guidelines advise against ultra-processed foods?</h2> Existing national <a href="https://www.eatforhealth.gov.au/sites/default/files/2022-09/n55_australian_dietary_guidelines.pdf">dietary</a> <a href="https://www.health.govt.nz/system/files/documents/publications/eating-activity-guidelines-new-zealand-adults-updated-2020-oct22.pdf">guidelines</a> have been developed and refined based on decades of nutrition evidence. Much of the recent evidence related to ultra-processed foods tells us what we already knew: that products like soft drinks, alcohol and processed meats are bad for health. Dietary guidelines <a href="https://pubmed.ncbi.nlm.nih.gov/35184508/">generally</a> already advise to eat mostly whole foods and to limit consumption of highly processed foods that are high in refined grains, saturated fat, sugar and salt. But some nutrition researchers have <a href="https://www.bmj.com/content/384/bmj.q439">called</a> for dietary guidelines to be amended to recommend avoiding ultra-processed foods. Based on the available evidence, it would be difficult to justify adding a sweeping statement about avoiding all ultra-processed foods. Advice to avoid all ultra-processed foods would likely unfairly impact people on low-incomes, as many ultra-processed foods, such as supermarket breads, are relatively affordable and convenient. Wholegrain breads also provide important nutrients, such as fibre. In many countries, bread is the <a href="https://www.health.govt.nz/system/files/documents/publications/a-focus-on-nutrition-ch3_0.pdf">biggest contributor</a> to fibre intake. So it would be problematic to recommend avoiding supermarket wholegrain bread just because it’s ultra-processed. <h2>So how can we improve our diets?</h2> There is strong <a href="https://www.foodpolicyindex.org.au/_files/ugd/7ee332_a2fa1694e42f423195caf581044fccf1.pdf">consensus</a> on the need to implement evidence-based policies to improve population diets. This includes legislation to restrict children’s exposure to the marketing of unhealthy foods and brands, mandatory Health Star Rating nutrition labelling and taxes on sugary drinks. These policies are underpinned by <a href="https://pubmed.ncbi.nlm.nih.gov/37659696/">well-established systems</a> for classifying the healthiness of foods. If new evidence unfolds about mechanisms by which ultra-processed foods drive health harms, these classification systems can be updated to reflect such evidence. If specific additives are found to be harmful to health, for example, this evidence can be incorporated into existing nutrient profiling systems, such as the <a href="http://www.healthstarrating.gov.au/internet/healthstarrating/publishing.nsf/content/home">Health Star Rating</a> food labelling scheme. Accordingly, policymakers can confidently progress food policy implementation using the tools for classifying the healthiness of foods that we already have. Unhealthy diets and obesity are among the <a href="https://www.aihw.gov.au/reports/burden-of-disease/burden-of-disease-study-2018-key-findings/contents/key-findings">largest contributors</a> to poor health. We can’t let the hype and academic debate around “ultra-processed” foods delay implementation of globally recommended policies for improving population diets.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/229493/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/gary-sacks-3957">Gary Sacks</a>, Professor of Public Health Policy, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>; <a href="https://theconversation.com/profiles/kathryn-backholer-10739">Kathryn Backholer</a>, Co-Director, Global Centre for Preventive Health and Nutrition, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>; <a href="https://theconversation.com/profiles/kathryn-bradbury-1532662">Kathryn Bradbury</a>, Senior Research Fellow in the School of Population Health, <a href="https://theconversation.com/institutions/university-of-auckland-waipapa-taumata-rau-1305">University of Auckland, Waipapa Taumata Rau</a>, and <a href="https://theconversation.com/profiles/sally-mackay-1532685">Sally Mackay</a>, Senior Lecturer Epidemiology and Biostatistics, <a href="https://theconversation.com/institutions/university-of-auckland-waipapa-taumata-rau-1305">University of Auckland, Waipapa Taumata Rau</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"He's a good kid": Teen fisherman's boss defends young millionaire

The former boss of teenager fisherman Keegan Payne has spoken out in support of the new millionaire, just days after Peter Stefanovic and Sky News were slammed for a "harsh" interview. On Wednesday, Stefanovic made headlines after he used his <a href="https://oversixty.com.au/finance/legal/peter-stefanovic-slammed-for-harsh-question-to-young-million-dollar-winner" target="_blank" rel="noopener">interview</a> with 19-year-old Payne, who had just won a million dollars in a fishing competition in the Northern Territory, to quiz the young man about a petty crime he committed when he was 16. "There is a claim online that you stole a Polaris Ranger and Polaris quad that you and your friends stole and damaged from a business a few years back, first of all, is that true?" Stefanovic asked from his Sydney studio during the live interview. Payne, who was speaking from the Darwin, simply answered, "Yes". Payne explained he and his friends "were young", and "weren't thinking at the time" but having come up with the idea they "went for it". Stefanovic asked Payne if he regretted the act and he said he did "big time". The interview was widely condemned online, with many saying Stefanovic "ripped the carpet from underneath" Payne and chose to focus on a past mistake rather than celebrate his life-changing win. The backlash to the interview prompted both Stefanovic and Sky News to issue an apology to Keegan, saying he "regrets" his line of questioning. “An apology from me, last Wednesday we invited Keegan Payne onto our show to discuss his win in the Million Dollar Fish competition in the Northern Territory,” Stefanovic said during First Edition on Monday. “During that interview I asked him about a theft that had occurred several years earlier. I should not have asked him about those claims and I regret doing so. “I apologise sincerely to Keegan and his family.” Now, the teenage fisherman's former boss, Bob Cavanagh, has spoken out in defence of Keegan, saying "he is a good kid" who had a lapse of better judgement. Cavanagh ran the business that Payne stole the vehicles from a few years ago, but said he does not hold a grudge and holds no ill will to the teenager. “He’s a good kid who made a mistake,” Cavanagh told the <a href="https://www.dailymail.co.uk/news/article-13384033/Keegan-Payne-Peter-Stefanovic-fishing-Bob-Cavanagh.html">Daily Mail</a>. “What was meant to be a celebratory moment was stolen from him. I’m glad he [Stefanovic] apologised to Keegan, he deserved that apology.” Cavanagh said he believes Stefanovic has learnt a lesson. “We all make mistakes and I bet he regrets it,’ he said. ‘The fact that he’s come out and apologised to Keegan and his family, I think he’s realised he’s overstepped the mark.” After his big win, Keegan offered to pay back the stolen vehicles. “Out of the blue this morning, his father rang me and said, ‘Keegan wants to repay you’, and you could have knocked me down with a feather,” Cavanagh said. “He said Keegan has always felt so terrible for what he did.” Image credits: Facebook <p style="box-sizing: inherit; margin: 0px 0px 24px; padding: 0px; border: 0px; font-stretch: inherit; line-height: inherit; font-size-adjust: inherit; font-kerning: inherit; font-variant-alternates: inherit; font-variant-ligatures: inherit; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-variant-position: inherit; font-feature-settings: inherit; font-optical-sizing: inherit; font-variation-settings: inherit; vertical-align: baseline;">

How bad is junk food for you, really?

<div> Consuming more junk foods, such as soft drinks, packaged snacks, and sugary cereals, is associated with a higher risk of more than 30 different health problems – both physical and mental – according to researchers. A study, known as an umbrella review, combined the results of 45 previous meta-analyses published in the last three years, representing about 10 million participants. Thirty-two different poor health outcomes were found to be linked to the consumption of ultra-processed foods (UPFs), with varying levels of evidence supporting the findings. The researchers found the most convincing evidence around higher ultra-processed food intake, which was associated with a 50% increased risk of cardiovascular disease-related death, a 48-53% higher risk of anxiety and common mental disorders, and a 12% greater risk of type 2 diabetes. Evidence marked as ‘highly suggestive’ included a 21% increase in death from any cause, a 40-66% increased risk of a heart disease related death, obesity, type 2 diabetes, and sleep problems, as well as a 22% increased risk of depression. The review also found there may be links between ultra-processed food and asthma; gastrointestinal health; some cancers; and other risk factors such as high blood fats and low levels of ‘good’ cholesterol, but the researchers note this evidence is limited. Dr Daisy Coyle from the George Institute for Global Health in Sydney, who was not involved in the research, says the statistics are “staggering.” “Ultra-processed foods, laden with additives and sometimes lacking in essential nutrients, have become ubiquitous in the Australian diet,” she says. “In fact, they make up almost half of what we buy at the supermarket. While not all ultra-processed foods are linked to poor health outcomes, many are, particularly sugary drinks and processed meats.” <div> </div> While the findings are in line with other research that highlights the health risks associated with UPFs, some experts have pointed out that the study is observational, and therefore can’t prove the ultra-processed foods cause these health issues. It can only show an association. “While these associations are interesting and warrant further high-quality research, they do not and cannot provide evidence of causality,” The University of Sydney’s Dr Alan Barclay told the AusSMC. “By their very nature, observational studies are renowned for being confounded by numerous factors – both known and unknown.” Clare Collins, Laureate Professor at the University of Newcastle agreed, but added that it’s difficult to conduct dietary studies like this in a different way. “The studies are observational, which means cause and effect cannot be proven and that the research evidence gets downgraded, compared to intervention studies,” she says. “The problem is that it is not ethical to do an intervention study lasting for many years where you feed people lots of UPF every day and wait for them to get sick and die.” For now, researchers seem to agree that it can’t be a bad thing to minimise UPF intake. The review suggests a need for policies that pull consumers away from ultra-processed foods, such as advertising restrictions, warning labels, bans in schools and hospitals. It also calls for measures that make healthier foods more accessible and affordable. Dr Charlotte Gupta from Central Queensland University suggests that this is issue of accessibility is particularly relevant for shift workers such as doctors, nurses, firefighters, taxi drivers, miners, and hospitality workers. “There is a lack of availability of fresh foods or time to prepare any food, and so ultra-processed foods have to be relied on (e.g. from the vending machine in the hospital),” she said. “This highlights the need for not only individuals to try reducing ultra-processed foods in our diet, but also for public health actions to improve access to healthier foods.” Image credits: Shutterstock <a href="https://cosmosmagazine.com/health/how-bad-is-junk-food-for-you-really/">This article</a> was originally published on <a href="https://cosmosmagazine.com">Cosmos Magazine</a> and was written by <a href="https://cosmosmagazine.com/contributor/olivia-henry/">Olivia Henry</a>. </div>

Woolies boss' multi-million dollar payout revealed

Chief executive Brad Banducci announced his <a href="https://www.oversixty.com.au/lifestyle/retirement-life/woolies-ceo-quits-after-disaster-interview" target="_blank" rel="noopener">early retirement </a>on Wednesday, following a series of PR disasters for the brand and just days after a <a href="https://www.oversixty.com.au/finance/money-banking/i-think-i-m-done-the-question-that-made-woolies-ceo-leave-interview" target="_blank" rel="noopener">trainwreck interview</a> with ABC Four Corners. Now, the staggering amount he will be paid-out for walking away from the top job has been revealed. According to a report published by The Australian, the supermarket boss will take home a share portfolio worth an estimated $24.4 million. This is in addition to the $6.5 million he would likely be paid-out from his salary. Banducci will step down from his position in September and he will be replaced by former WooliesX leader <a href="https://www.oversixty.com.au/finance/money-banking/new-woolies-ceo-s-huge-salary-revealed" target="_blank" rel="noopener">Amanda Bardwell</a>, who will take over as Chief Executive then. Woolworths Group has denied the suggestion that the resignation was related to the disaster Four Corners interview where Banducci tried to walk away in the middle of being questioned about price gouging. A senate inquiry is also currently investigating whether major supermarkets across the country have engaged in price gouging, as the cost-of-living continues to rise. Banducci has been involved in a series of public controversies before his retirement, including when he came under fire after the supermarket announced it would <a href="https://www.oversixty.com.au/finance/money-banking/woolworths-under-fire-for-dropping-australia-day-merch" target="_blank" rel="noopener">stop selling Australia Day merchandise </a>ahead of the national holiday in January.

Why it’s a bad idea to mix alcohol with some medications

<a href="https://theconversation.com/profiles/nial-wheate-96839">Nial Wheate</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/jasmine-lee-1507733">Jasmine Lee</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/kellie-charles-1309061">Kellie Charles</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/tina-hinton-329706">Tina Hinton</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Anyone who has drunk alcohol will be familiar with how easily it can lower your social inhibitions and let you do things you wouldn’t normally do. But you may not be aware that mixing certain medicines with alcohol can increase the effects and put you at risk. When you mix alcohol with medicines, whether prescription or over-the-counter, the medicines can increase the effects of the alcohol or the alcohol can increase the side-effects of the drug. Sometimes it can also result in all new side-effects. <h2>How alcohol and medicines interact</h2> The chemicals in your brain maintain a delicate balance between excitation and inhibition. Too much excitation can lead to <a href="https://www.medicalnewstoday.com/articles/324330">convulsions</a>. Too much inhibition and you will experience effects like sedation and depression. <iframe id="JCh01" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/JCh01/1/" width="100%" height="400px" frameborder="0"></iframe> Alcohol works by increasing the amount of inhibition in the brain. You might recognise this as a sense of relaxation and a lowering of social inhibitions when you’ve had a couple of alcoholic drinks. With even more alcohol, you will notice you can’t coordinate your muscles as well, you might slur your speech, become dizzy, forget things that have happened, and even fall asleep. Medications can interact with alcohol to <a href="https://awspntest.apa.org/record/2022-33281-033">produce different or increased effects</a>. Alcohol can interfere with the way a medicine works in the body, or it can interfere with the way a medicine is absorbed from the stomach. If your medicine has similar side-effects as being drunk, those <a href="https://www.drugs.com/article/medications-and-alcohol.html#:%7E:text=Additive%20effects%20of%20alcohol%20and,of%20drug%20in%20the%20bloodstream.">effects can be compounded</a>. Not all the side-effects need to be alcohol-like. Mixing alcohol with the ADHD medicine ritalin, for example, can <a href="https://www.healthline.com/health/adhd/ritalin-and-alcohol#side-effects">increase the drug’s effect on the heart</a>, increasing your heart rate and the risk of a heart attack. Combining alcohol with ibuprofen can lead to a higher risk of stomach upsets and stomach bleeds. Alcohol can increase the break-down of certain medicines, such as <a href="https://www.sciencedirect.com/science/article/abs/pii/S0149763421005121?via%3Dihub">opioids, cannabis, seizures, and even ritalin</a>. This can make the medicine less effective. Alcohol can also alter the pathway of how a medicine is broken down, potentially creating toxic chemicals that can cause serious liver complications. This is a particular problem with <a href="https://australianprescriber.tg.org.au/articles/alcohol-and-paracetamol.html">paracetamol</a>. At its worst, the consequences of mixing alcohol and medicines can be fatal. Combining a medicine that acts on the brain with alcohol may make driving a car or operating heavy machinery difficult and lead to a serious accident. <h2>Who is at most risk?</h2> The effects of mixing alcohol and medicine are not the same for everyone. Those most at risk of an interaction are older people, women and people with a smaller body size. Older people do not break down medicines as quickly as younger people, and are often on <a href="https://www.safetyandquality.gov.au/our-work/healthcare-variation/fourth-atlas-2021/medicines-use-older-people/61-polypharmacy-75-years-and-over#:%7E:text=is%20this%20important%3F-,Polypharmacy%20is%20when%20people%20are%20using%20five%20or%20more%20medicines,take%20five%20or%20more%20medicines.">more than one medication</a>. Older people also are more sensitive to the effects of medications acting on the brain and will experience more side-effects, such as dizziness and falls. Women and people with smaller body size tend to have a higher blood alcohol concentration when they consume the same amount of alcohol as someone larger. This is because there is less water in their bodies that can mix with the alcohol. <h2>What drugs can’t you mix with alcohol?</h2> You’ll know if you can’t take alcohol because there will be a prominent warning on the box. Your pharmacist should also counsel you on your medicine when you pick up your script. The most common <a href="https://adf.org.au/insights/prescription-meds-alcohol/">alcohol-interacting prescription medicines</a> are benzodiazepines (for anxiety, insomnia, or seizures), opioids for pain, antidepressants, antipsychotics, and some antibiotics, like metronidazole and tinidazole. It’s not just prescription medicines that shouldn’t be mixed with alcohol. Some over-the-counter medicines that you shouldn’t combine with alcohol include medicines for sleeping, travel sickness, cold and flu, allergy, and pain. Next time you pick up a medicine from your pharmacist or buy one from the local supermarket, check the packaging and ask for advice about whether you can consume alcohol while taking it. If you do want to drink alcohol while being on medication, discuss it with your doctor or pharmacist first.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/223293/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/nial-wheate-96839">Nial Wheate</a>, Associate Professor of the School of Pharmacy, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/jasmine-lee-1507733">Jasmine Lee</a>, Pharmacist and PhD Candidate, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/kellie-charles-1309061">Kellie Charles</a>, Associate Professor in Pharmacology, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/tina-hinton-329706">Tina Hinton</a>, Associate Professor of Pharmacology, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Anger, sadness, boredom, anxiety – emotions that feel bad can be useful

<a href="https://theconversation.com/profiles/heather-lench-1349234">Heather Lench</a>, <a href="https://theconversation.com/institutions/texas-aandm-university-1672">Texas A&M University</a> Remember the sadness that came with the last time you failed miserably at something? Or the last time you were so anxious about an upcoming event that you couldn’t concentrate for days? These types of emotions are unpleasant to experience and can even feel overwhelming. People often try to avoid them, suppress them or ignore them. In fact, in psychology experiments, people will <a href="https://doi.org/10.1007/s10902-012-9394-7">pay money to not feel many negative emotions</a>. But recent research is revealing that emotions can be useful, and even negative emotions can bring benefits. <a href="https://scholar.google.com/citations?user=fzHtrJIAAAAJ&hl=en&oi=ao">In my</a> <a href="https://emotionsciencelab.com">emotion science lab</a> at Texas A&M University, we study how emotions like anger and boredom affect people, and we explore ways that these feelings can be beneficial. We share the results so people can learn how to use their emotions to build the lives they want. Our studies and many others have shown that emotions aren’t uniformly good or bad for people. Instead, different emotions can result in better outcomes in particular types of situations. Emotions seem to function like a Swiss army knife – different emotional tools are helpful in specific situations. <h2>Sadness can help you recover from a failure</h2> Sadness occurs when people perceive that they’ve lost a goal or a desired outcome, and there’s nothing they can do to improve the situation. It could be getting creamed in a game or failing a class or work project, or it can be losing a relationship with a family member. Once evoked, sadness is associated with what psychologists call a deactivation state of doing little, without much behavior or <a href="https://dictionary.apa.org/arousal">physical arousal</a>. Sadness also brings <a href="https://doi.org/10.1111/ap.12232">thinking that is more detailed and analytical</a>. It makes you stop <a href="https://doi.org/10.1177/0963721412474458">and think</a>. The benefit of the stopping and thinking that comes with sadness is that it <a href="https://doi.org/10.1007/978-3-319-77619-4_4">helps people recover from failure</a>. When you fail, that typically means the situation you’re in is not conducive to success. Instead of just charging ahead in this type of scenario, sadness prompts people to step back and <a href="https://doi.org/10.1037/a0016242">evaluate what is happening</a>. When people are sad, they process information in a deliberative, analytical way and want to avoid risk. This mode comes with <a href="https://doi.org/10.1037/0022-3514.75.2.318">more accurate memory</a>, <a href="https://doi.org/10.1080/02699939108411048">judgment that is less influenced</a> <a href="https://doi.org/10.1016/j.jesp.2004.11.005">by irrelevant assumptions or information</a>, and <a href="https://doi.org/10.1016/j.jesp.2008.04.010">better detection of other people lying</a>. These cognitive changes can encourage people to understand past failures and possibly prevent future ones. Sadness can function differently when there’s the possibility that the failure could be avoided if other people help. In these situations, people tend to <a href="https://doi.org/10.1111/j.1469-8986.1994.tb01049.x">cry and can experience</a> <a href="https://doi.org/10.1007/s10286-018-0526-y">increased physiological arousal</a>, such as quicker heart and breathing rates. Expressing sadness, through tears or verbally, has the benefit of <a href="https://doi.org/10.1177/147470491301100114">potentially recruiting other people to help you</a> achieve your goals. This behavior appears to start in infants, with <a href="https://doi.org/10.2307/1127506">tears and cries signaling caregivers to help</a>. <h2>Anger prepares you to overcome an obstacle</h2> Anger occurs when people perceive they’re losing a goal or desired outcome, but that they could improve the situation by removing something that’s in their way. The obstacle could be an injustice committed by another person, or it could be a computer that repeatedly crashes while you’re trying to get work done. Once evoked, <a href="https://doi.org/10.1037/a0024244">anger is associated with a “readiness for action,”</a> and your <a href="https://doi.org/10.1016/S0191-8869(02)00313-6">thinking focuses on the obstacle</a>. The benefit of being prepared for action and focused on what’s in your way is that it motivates you to overcome what’s standing between you and your goal. <a href="https://doi.org/10.1177/1754073913512003">When people are angry</a>, they <a href="https://doi.org/10.1002/ejsp.2420240104">process information and make judgments rapidly</a>, want to take action, and are <a href="https://doi.org/10.1016/j.biopsycho.2010.03.010">physiologically aroused</a>. In experiments, <a href="https://doi.org/10.1016/j.paid.2010.04.017">anger actually increases the force of people’s kicks</a>, which can be helpful in physical encounters. Anger results in better outcomes in situations that involve challenges to goals, including confrontational games, <a href="https://doi.org/10.1037/pspa0000350">tricky puzzles</a>, video games with obstacles, and responding quickly on tasks. Expressing anger, facially or verbally, has the benefit of <a href="http://dx.doi.org/10.1037/pspp0000292">prompting other people to clear the way</a>. People are <a href="https://doi.org/10.1037/0022-3514.86.1.57">more likely to concede in negotiations</a> and <a href="https://doi.org/10.1016/j.jesp.2012.12.015">give in on issues</a> when their adversary looks or says they are angry. <h2>Anxiety helps you prepare for danger</h2> Anxiety occurs when people <a href="https://doi.org/10.1177/070674371105601202">perceive a potential threat</a>. This could be giving a speech to a large audience where failure would put your self-esteem on the line, or it could be a physical threat to yourself or loved ones. Once evoked, anxiety is associated with being prepared to respond to danger, including increased physical arousal and <a href="https://doi.org/10.1111/j.1467-9280.2006.01701.x">attention to threats and risk</a>. Being prepared for danger means that if trouble brews, you can respond quickly to prevent or avoid it. When anxious, people detect threats rapidly, have fast reaction times and <a href="https://doi.org/10.1111/j.1467-9280.2006.01701.x">are on heightened alert</a>. The eye-widening that often comes with fear and anxiety even <a href="https://doi.org/10.1038/nn.2138">gives people a wider field of vision</a> and improves threat detection. Anxiety prepares the body for action, which improves performance on a number of tasks that involve motivation and attention. It motivates people to prepare for upcoming events, such as devoting time to study for an exam. Anxiety also prompts protective behavior, which can help prevent the potential threat from becoming a reality. <h2>Boredom can jolt you out of a rut</h2> There is less research on boredom than many other emotions, so it is not as well understood. Researchers debate <a href="https://doi.org/10.1016/j.tics.2023.02.002">what it is</a> and <a href="https://doi.org/10.3390/bs3030459">what it does</a>. Boredom appears to occur when someone’s current situation is <a href="https://doi.org/10.3390/bs3030459">not causing any other emotional response</a>. There are three situations <a href="https://doi.org/10.1007/s11031-011-9234-9">where this lack can occur</a>: when emotions fade, such as the happiness of a new car fading to neutral; when people don’t care about anything in their current situation, such as being at a large party where nothing interesting is happening; or when people have no goals. Boredom does not necessarily set in just because nothing is happening – someone with a goal of relaxation might feel quite content sitting quietly with no stimulation. Psychology researchers think that the benefit of boredom in situations where people are not responding emotionally is that it <a href="http://dx.doi.org/10.1037/emo0000433">prompts making a change</a>. If nothing in your current situation is worth responding to, the <a href="https://doi.org/10.1002/jocb.154">aversive experience of boredom can motivate you</a> to seek new situations or change the way you’re thinking. Boredom has been related to more risk seeking, a desire for novelty, and creative thinking. It seems to function like an emotional stick, nudging people out of their current situation to explore and create. <h2>Using the toolkit of emotion</h2> People want to be happy. But research is finding that a satisfying and productive life includes a <a href="http://dx.doi.org/10.1037/pspp0000292">mix of positive and negative emotions</a>. Negative emotions, even though they feel bad to experience, can motivate and prepare people for failure, challenges, threats and exploration. Pleasant or not, your emotions can help guide you toward better outcomes. Maybe understanding how they prepare you to handle various situations will help you feel better about feeling bad.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/217654/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/heather-lench-1349234">Heather Lench</a>, Professor of Psychological and Brain Sciences, <a href="https://theconversation.com/institutions/texas-aandm-university-1672">Texas A&M University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.
