  • Covering obesity: 6 tips for dispelling myths and avoiding stigmatizing news coverage

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    When researchers looked at news coverage of obesity in the United States and the United Kingdom a few years ago, they found that images in news articles often portrayed people with larger bodies “in a stigmatizing manner” — they emphasized people’s abdomens, for example, or showed them eating junk food, wearing tight clothes or lounging in front of a TV. 

    When people with larger bodies were featured in photos and videos, nearly half were shown only from their necks down or with part of their heads missing, according to the analysis, published in November 2023. The researchers examined a total of 445 images posted to the websites of four U.S. news outlets and four U.K. news outlets between August 2018 and August 2019.

    The findings underscore the need for dramatic changes in the way journalists report on obesity and people who weigh more than what medical authorities generally consider healthy, Rebecca Puhl, one of the paper’s authors, told The Journalist’s Resource in an email interview.

    “Using images of ‘headless stomachs’ is dehumanizing and stigmatizing, as are images that depict people with larger bodies in stereotypical ways (e.g., eating junk food or being sedentary),” wrote Puhl, deputy director of the Rudd Center for Food Policy and Health at the University of Connecticut and a leading scholar on weight stigma.

    She noted that news images influence how the public views and interacts with people with obesity, a complicated and often misunderstood condition that the American Medical Association considers a disease.

    In the U.S., an estimated 42% of adults aged 20 years and older have obesity, a number researchers predict will rise to 50% over the next six years. While the disease isn’t as common in other parts of the planet, the World Obesity Federation projects that by 2035, more than half the global population will have obesity or overweight.

    Several other studies Puhl has conducted demonstrate that biased new images can have damaging consequences for individuals affected by obesity.

    “Our research has found that seeing the stigmatizing image worsens people’s attitudes and weight bias, leading them to attribute obesity to laziness, increasing their dislike of people with higher weight, and increasing desire for social distance from them,” Puhl explained.

    Dozens of studies spotlight problems in news coverage of obesity in the U.S. and abroad. In addition to stigmatizing images, journalists use stigmatizing language, according to a 2022 research review in eClinicalMedicine, a journal published by The Lancet.

    The research also suggests people with higher weights feel excluded and ridiculed by news outlets.

    “Overt or covert discourses in news media, social media, and public health campaigns included depictions of people with overweight or obesity as being lazy, greedy, undisciplined, unhappy, unattractive, and stupid,” write the authors of the review, which examines 113 academic studies completed before Dec. 2, 2021.

    To help journalists reflect on and improve their work, The Journalist’s Resource asked for advice from experts in obesity, weight stigma, health communication and sociolinguistics. They shared their thoughts and opinions, which we distilled into the six tips that appear below.

    In addition to Puhl, we interviewed these six experts:

    Jamy Ard, a professor of epidemiology and prevention at Wake Forest University School of Medicine and co-director of the Wake Forest Baptist Health Weight Management Center. He’s also president of The Obesity Society, a professional organization of researchers, health care providers and other obesity specialists.

    Leslie Cofie, an assistant professor of health education and promotion at East Carolina University’s College of Health and Human Performance. He has studied obesity among immigrants and military veterans.

    Leslie Heinberg, director of Enterprise Weight Management at the Cleveland Clinic, an academic medical center. She’s also vice chair for psychology in the Cleveland Clinic’s Center for Behavioral Health Department of Psychiatry and Psychology.

    Monu Khanna, a physician in Missouri who is board certified in obesity medicine.

    Jenn Lonzer, manager of the Cleveland Clinic Health Library and the co-author of several academic papers on health communication.

    Cindi SturtzSreetharan, an anthropologist and professor at the Arizona State University School of Human Evolution and Social Change. She studies the language people of different cultures use to describe human bodies.

    1. Familiarize yourself with recent research on what causes obesity and how obesity can affect a person’s health. Many long-held beliefs about the disease are wrong.

    Journalists often report incorrect or misleading information about obesity, possibly because they’re unaware that research published in recent decades dispels many long-held beliefs about the disease, the experts say. Obesity isn’t simply the result of eating too many calories and doing too little exercise. A wide range of factors drive weight gain and prevent weight loss, many of which have nothing to do with willpower or personal choices.

    Scholars have learned that stress, gut health, sleep duration and quality, genetics, medication, personal income, access to healthy foods and even climate can affect weight regulation. Prenatal and early life experiences also play a role. For example, childhood trauma such as child abuse can become “biologically embedded,” altering children’s brain structures and influencing their long-term physical and mental health, according to a 2020 research review published in the journal Physiology & Behavior.

    “The causes of obesity are numerous and each individual with obesity will have a unique set of contributors to their excess weight gain,” Jamy Ard, president of The Obesity Society, wrote to The Journalist’s Resource.

    The experts urge journalists to help dispel myths, correct misinformation and share new research findings. News outlets should examine their own work, which often “ignores the science and sets up situation blaming,” says Leslie Heinberg, director of Enterprise Weight Management at the Cleveland Clinic.

    “So much of the media portrayal is simply ‘This is a person who eats too much and the cure is simply to eat less or cut out that food’ or something overly, overly simplistic,” Heinberg says.

    Journalists need to build their knowledge of the problem before they can explain it to their audiences. Experts point out that educating policymakers, health care providers and the public about obesity is key to eliminating the stigma associated with having a larger body.

    Weight stigma alone is so physically and emotionally damaging that 36 international experts issued a consensus statement in 2020 to raise awareness about it. The document, endorsed by dozens of medical and academic organizations, outlines 13 recommendations for eliminating weight bias and stigma.

    Recommendation No. 5: “We call on the media to produce fair, accurate, and non-stigmatizing portrayals of obesity. A commitment from the media is needed to shift the narrative around obesity.”

    2. Use person-first language — the standard among health and medical professionals for communicating about people with chronic diseases.

    The experts we interviewed encourage journalists to ditch the adjectives “obese” and “overweight” because they are dehumanizing. Use person-first language, which avoids labeling people as their disease by putting the person before the disease.

    Instead of saying “an obese teenager,” say “a teenager who has obesity” or “a teenager affected by obesity.” Instead of writing “overweight men,” write “men who have overweight.”

    Jenn Lonzer, manager of the Cleveland Clinic Health Library, says using “overweight” as a noun might look and sound awkward at first. But it makes sense considering other diseases are treated as nouns, she notes. Journalists would not typically refer to someone in a news story as “a cancerous person,” for example. They would report that the individual has cancer.

    It’s appropriate to refer to people with overweight or obesity using neutral weight terminology. Puhl wrote that she uses “people with higher body weight” or “people with high weight” and, sometimes, “people with larger bodies” in her own writing.

    While the Associated Press stylebook offers no specific guidance on the use of terms such as “obese” or “overweight,” it advises against “general and often dehumanizing ‘the’ labels such as the poor, the mentally ill, the disabled, the college-educated.”

    The Association of Health Care Journalists recommends person-first language when reporting on obesity. But it also advises journalists to ask sources how they would like to be characterized, provided their weight or body size is relevant to the news story.

    Anthropologist Cindi SturtzSreetharan, who studies language and culture, says sources’ responses to that question should be part of the story. Some individuals might prefer to be called “fat,” “thick” or “plus-sized.”

    “I would include that as a sentence in the article — to signal you’ve asked and that’s how they want to be referred to,” SturtzSreetharan says.

    She encourages journalists to read how authors describe themselves in their own writing. Two books she recommends: Thick by Tressie McMillan Cottom and Heavy: An American Memoir by Kiese Laymon.

    3. Carefully plan and choose the images that will accompany news stories about obesity.

    Journalists need to educate themselves about stigma and screen for it when selecting images, Puhl noted. She shared these four questions that journalists should ask themselves when deciding how to show people with higher weights in photos and video.

    • Does the image imply or reinforce negative stereotypes?
    • Does it provide a respectful portrayal of the person?
    • Who might be offended, and why?
    • Can an alternative image convey the same message and eliminate possible bias?

    “Even if your written piece is balanced, accurate, and respectful, a stigmatizing image can undermine your message and promote negative societal attitudes,” Puhl wrote via email.

    Lonzer says newsrooms also need to do a better job incorporating images of people who have different careers, interests, education levels and lifestyles into their coverage of overweight and obesity.

    “We are diverse,” says Lonzer, who has overweight. “We also have diversity in body shape and size. It’s good to have images that reflect what Americans look like.”

    If you’re looking for images and b-roll videos that portray people with obesity in non-stigmatizing ways, check out the Rudd Center Media Gallery. It’s a collection of original images of people from various demographic groups that journalists can use for free in their coverage.

    The Obesity Action Coalition, a nonprofit advocacy organization, also provides images. But journalists must sign up to use the OAC Bias-Free Image Gallery.

    Other places to find free images: The World Obesity Image Bank, a project of the World Obesity Federation, and the Flickr account of Obesity Canada.

    4. Make sure your story does not reinforce stereotypes or insinuate that overcoming obesity is simply a matter of cutting calories and doing more exercise.

    “Think about the kinds of language used in the context of eating habits or physical activity, as some can reinforce shame or stereotypes,” Puhl wrote.

    She suggested journalists avoid phrases such as “resisting temptations,” “cheating on a diet,” “making excuses,” “increasing self-discipline” and “lacking self-control” because they perpetuate the myth that individuals can control their weight and that the key to losing weight is eating less and moving more.

    Lonzer offers this advice: As you work on stories about obesity or weight-related issues, ask yourself if you would use the same language and framing if you were reporting on someone you love.

    Here are other questions for journalists to contemplate:

    “Am I treating this as a complex medical condition or am I treating it as ‘Hey, lay off the French fries?’” Lonzer adds. “Am I treating someone with obesity differently than someone with another disease?”

    It’s important to also keep in mind that having excess body fat does not, by itself, mean a person is unhealthy. And don’t assume everyone who has a higher weight is unhappy about it.

    “Remember, not everyone with obesity is suffering,” physician Monu Khanna wrote to The Journalist’s Resource.

    5. To help audiences understand how difficult it is to prevent and reduce obesity, explain that even the places people live can affect their waistlines.

    When news outlets report on obesity, they often focus on weight-loss programs, surgical procedures and anti-obesity medications. But there are other important issues to cover. Experts stress the need to help the public understand how factors not ordinarily associated with weight gain or loss can influence body size.

    For example, a paper published in 2018 in the American Journal of Preventive Medicine indicates adults who are regularly exposed to loud noise have a higher waist circumference than adults who are not. Research also finds that people who live in neighborhoods with sidewalks and parks are more active.

    “One important suggestion I would offer to journalists is that they need to critically explore environmental factors (e.g., built environment, food deserts, neighborhood safety, etc.) that lead to disproportionately high rates of obesity among certain groups, such as low-income individuals and racial/ethnic minorities,” Leslie Cofie, an assistant professor at East Carolina University, wrote to The Journalist’s Resource.

    Cofie added that moving to a new area can prompt weight changes.

    “We know that immigrants generally have lower rates of obesity when they first migrate to the U.S.,” he wrote. “However, over time, their obesity rates resemble that of their U.S.-born counterparts. Hence, it is critical for journalists to learn about how the sociocultural experiences of immigrants change as they adapt to life in the U.S. For example, cultural perspectives about food, physical activities, gender roles, etc. may provide unique insights into how the pre- and post-migration experiences of immigrants ultimately contribute to the unfavorable trends in their excessive weight gain.”

    Other community characteristics have been linked to larger body sizes for adults or children: air pollution, lower altitudes, higher temperatures, lower neighborhood socioeconomic status, perceived neighborhood safety, an absence of local parks and closer proximity to fast-food restaurants.

    6. Forge relationships with organizations that study obesity and advocate on behalf of people living with the disease.

    Several organizations are working to educate journalists about obesity and help them improve their coverage. Five of the most prominent ones collaborated on a 10-page guide book, “Guidelines for Media Portrayals of Individuals Affected by Obesity.”

    • The Rudd Center for Food Policy and Health, based at the University of Connecticut, “promotes solutions to food insecurity, poor diet quality, and weight bias through research and policy,” according to its website. Research topics include food and beverage marketing, weight-related bullying and taxes on sugary drinks.
    • The Obesity Society helps journalists arrange interviews with obesity specialists. It also offers journalists free access to its academic journal, Obesity, and free registration to ObesityWeek, an international conference of researchers and health care professionals held every fall. This year’s conference is Nov. 2-6 in San Antonio, Texas.
    • The Obesity Medicine Association represents health care providers who specialize in obesity treatment and care. It also helps journalists connect with obesity experts and offers, on an individual basis, free access to its events, including conferences and Obesity Medicine Fundamentals courses.
    • The Obesity Action Coalition offers free access to its magazine, Weight Matters, and guides on weight bias at work and in health care.
    • The American Society for Metabolic and Bariatric Surgery represents surgeons and other health care professionals who work in the field of metabolic and bariatric surgery. It provides the public with resources such as fact sheets and brief explanations of procedures such as the Roux-en-Y Gastric Bypass.

  • Why Some People Get Sick More (And How To Not Be One Of Them)

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Some people have never yet had COVID (so far so good, this writer included); others are on their third bout already; others have not been so lucky and are no longer with us to share their stories.

    Obviously, even the healthiest and/or most careful person can get sick, and it would be folly to be complacent and think “I’m not a person who gets sick; that happens to other people”.

    Nor is COVID the only thing out there to worry about; there’s always the latest outbreak-du-jour of something, and there are always the perennials such as cold and flu—which are also not to be underestimated, because both weaken us to other things, and flu has killed very many, from the 50,000,000+ in the 1918 pandemic, to the 700,000ish that it kills each year nowadays.

    And then there are the combination viruses:

    Move over, COVID and Flu! We Have “Hybrid Viruses” To Contend With Now

    So, why are some people more susceptible?

    Firstly, some people are simply immunocompromised. This means for example that:

    • perhaps they have an inflammatory/autoimmune disease of some kind (e.g. lupus, rheumatoid arthritis, type 1 diabetes), or…
    • perhaps they are taking immunosuppressants for some reason (e.g. because they had an organ transplant), or…
    • perhaps they have a primary infection that leaves them vulnerable to secondary infections. Most infections will do this to some degree or another, but some are worse for it than others; untreated HIV is a clear example. The HIV itself may not kill people, but (if untreated) the resultant AIDS will leave a person open to being killed by almost any passing opportunistic pathogen. Pneumonia of various kinds being high on the list, but it could even be something as simple as the common cold, without a working immune system to fight it.

    See also: How To Prevent (Or Reduce) Inflammation

    And for that matter, since pneumonia is a very common last-nail-in-the-coffin secondary infection (especially: older people going into hospital with one thing, getting a secondary infection and ultimately dying as a result), it’s particularly important to avoid that, so…

    See also: Pneumonia: What We Can & Can’t Do About It

    Secondly, some people are not immunocompromised per the usual definition of the word, but their immune system is, arguably, compromised.

    Cortisol, the stress hormone, is an immunosuppressant. We need cortisol to live, but we only need it in small bursts here and there (such as when we are waking up the morning). When high cortisol levels become chronic, so too does cortisol’s immunosuppressant effect.

    Top things that cause elevated cortisol levels include:

    • Stress
    • Alcohol
    • Smoking

    Thus, the keys here are to 1) not smoke 2) not drink, ideally, or at least keep consumption low, but honestly even one drink will elevate cortisol levels, so it’s better not to, and 3) manage stress.

    See also: Lower Your Cortisol! (Here’s Why & How)

    Other modifiable factors

    Being aware of infection risk and taking steps to reduce it (e.g. avoiding being with many people in confined indoor places, masking as appropriate, handwashing frequently) is a good preventative strategy, along with of course getting any recommended vaccines as they come available.

    What if they fail? How can we boost the immune system?

    We talked about not sabotaging the immune system, but what about actively boosting it? The answer is yes, we certainly can (barring serious medical reasons why not), as there are some very important lifestyle factors too:

    Beyond Supplements: The Real Immune-Boosters!

    One final last-line thing…

    Since if we do get an infection, it’s better to know sooner rather than later… A recent study shows that wearable activity trackers can (if we pay attention to the right things) help predict disease, including highlighting COVID status (positive or negative) about as accurately (88% accuracy) as rapid screening tests. Here’s a pop-science article about it:

    Wearable activity trackers show promise in detecting early signals of disease

  • Dates vs Figs – Which is Healthier?

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Our Verdict

    When comparing dates to figs, we picked the dates.

    Why?

    Dates are higher in sugar, but also have a lower glycemic index than figs, which makes the sugar content much healthier. On the flipside, figs do have around 3x more fiber.

    So far, so balanced.

    When it comes to micronutrients though, dates take the prize much more clearly.

    Dates have slightly more of most vitamins, and a lot more of most minerals.

    In particular, dates are several times higher in copper, iron, magnesium, manganese, phosphorus, selenium, and zinc.

    As for other phytochemical benefits going on:

    • both are good against diabetes for reasons beyond the macros
    • both have anti-inflammatory properties
    • dates have anticancer properties
    • dates have kidney-protecting properties

    So in this last case, another win for dates.

    Both are still great though, so do enjoy both!

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Our “to-do” lists are usually hopelessly tangled:

    To do thing x needs thing y doing first but that can only be done with information that I must get by doing thing z”, and so on.

    Suddenly that two-minute task is looking like half an hour, which is making our overall to-do list look gargantuan. Tackling tiny parts of tasks seems useless; tackling large tasks seems overwhelming. What a headache!

    Getting Things Done (“GTD”, to its friends) shows us how to gather all our to-dos, and then use the quickest ways to break down a task (in reality, often a mini-project) into its constituent parts and which things can be done next, and what order to do them in (or defer, or delegate, or ditch).

    In a nutshell: The GTD system aims to make all your tasks comprehensible and manageable, for stress-free productivity. No need to strategize everything every time; you have a system now, and always know where to begin.

    And by popular accounts, it delivers—many put this book in the “life-changing” category.

  • If Your Adult Kid Calls In Crisis…

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Parent(s) To The Rescue?

    We’ve written before about the very common (yes, really, it is common) phenomenon of estrangement between parents and adult children:

    Family Estrangement & How To Fix It

    We’ve also written about the juggling act that can be…

    Managing Sibling Relationships In Adult Life

    …which includes dealing with such situations as supporting each other through difficult times, while still maintaining healthy boundaries.

    But what about when one’s [adult] child is in crisis?

    When a parent’s job never ends

    Hopefully, we have not been estranged (or worse, bereaved) by our children.

    In which case, when crisis hits, we are likely to be amongst the first to whom our children will reach out for support. Naturally, we will want to help. But how can we do that, and where (if applicable) to draw the line?

    No “helicopter parenting”

    If you’ve not heard the term “helicopter parenting”, it refers to the sort of parents who hover around, waiting to swoop in at a moment’s notice.

    This is most often applied to parents of kids of university age and downwards, but it’s worth keeping it in mind at any age.

    After all, we do want our kids to be able to solve their own problems if possible!

    So, if you’ve ever advised your kid to “take a deep breath and count to 10” (or even if you haven’t), then, consider doing that too, and then…

    Listen first!

    If your first reaction isn’t to join them in panic, it might be to groan and “oh not again”. But for now, quietly shelve that, and listen to whatever it is.

    See also: Active Listening (Without Sounding Like A Furby)

    And certainly, do your best to maintain your own calm while listening. Your kid is in all likelihood looking to you to be the rock in the storm, so let’s be that.

    Empower them, if you can

    Maybe they just needed to vent. If so, the above will probably cover it.

    More likely, they need help.

    Perhaps they need guidance, from your greater life experience. Sometimes things that can seem like overwhelming challenges to one person, are a thing we dealt with 20 or more years ago (it probably felt overwhelming to us at the time, too, but here we are, the other side of it).

    Tip: ask “are you looking for my guidance/advice/etc?” before offering it. Doing so will make it much more likely to be accepted rather than rejected as unsolicited advice.

    Chances are, they will take the life-ring offered.

    It could be that that’s not what they had in mind, and they’re looking for material support. If so…

    When it’s about money or similar

    Tip: it’s worth thinking about this sort of thing in advance (now is great, if you have adult kids), and ask yourself nowwhat you’d be prepared to give in that regard, e.g:

    • if they need money, how much (if any) are you willing and able to provide?
    • if they want/need to come stay with you, how prepared are you for that (including: if they want/need to actually move back in with you for a while, which is increasingly common these days)?

    Having these answers in your head ready will make the conversation a lot less difficult in the moment, and will avoid you giving a knee-jerk response you might regret (in either direction).

    Have a counteroffer up your sleeve if necessary

    Maybe:

    • you can’t solve their life problem for them, but you can help them find a therapist (if applicable, for example)
    • you can’t solve their money problem for them, but you can help them find a free debt advice service (if applicable, for example)
    • you can’t solve their residence problem for them, but you can help them find a service that can help with that (if applicable, for example)

    You don’t need to brainstorm now for every option; you’re a parent, not Batman. But it’s a lot easier to think through such hypothetical thought-experiments now, than it will be with your fraught kid on the phone later.

    Magic words to remember: “Let’s find a way through this for you”

    Don’t forget to look after yourself

    Many of us, as parents, will tend to not think twice before sacrificing something for our kid(s). That’s generally laudable, but we must avoid accidentally becoming “the giving tree” who has nothing left for ourself, and that includes our mental energy and our personal peace.

    That doesn’t mean that when our kid comes in crisis we say “Shh, stop disturbing my personal peace”, but it does mean that we remember to keep at least some boundaries (also figure out now what they are, too!), and to take care of ourselves too.

    The following article was written with a slightly different scenario in mind, but the advice remains just as valid here:

  • Stickers and wristbands aren’t a reliable way to prevent mosquito bites. Here’s why

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Protecting yourself and family from mosquito bites can be challenging, especially in this hot and humid weather. Protests from young children and fears about topical insect repellents drive some to try alternatives such as wristbands, patches and stickers.

    These products are sold online as well as in supermarkets, pharmacies and camping stores. They’re often marketed as providing “natural” protection from mosquitoes.

    But unfortunately, they aren’t a reliable way to prevent mosquito bites. Here’s why – and what you can try instead.

    Why is preventing mosquito bites important?

    Mosquitoes can spread pathogens that make us sick. Japanese encephalitis and Murray Valley encephalitis viruses can have potentially fatal outcomes. While Ross River virus won’t kill you, it can cause potentially debilitating illnesses.

    Health authorities recommend preventing mosquito bites by: avoiding areas and times of the day when mosquitoes are most active; covering up with long sleeved shirts, long pants, and covered shoes; and applying a topical insect repellent (a cream, lotion, or spray).

    I don’t want to put sticky and smelly repellents on my skin!

    While for many people, the “sting” of a biting mosquitoes is enough to prompt a dose of repellent, others are reluctant. Some are deterred by the unpleasant feel or smell of insect repellents. Others believe topical repellents contain chemicals that are dangerous to our health.

    However, many studies have shown that, when used as recommended, these products are safe to use. All products marketed as mosquito repellents in Australia must be registered by the Australian Pesticides and Veterinary Medicines Authority; a process that provides recommendations for safe use.

    How do topical repellents work?

    While there remains some uncertainty about how the chemicals in topical insect repellents actually work, they appear to either block the sensory organs of mosquitoes that drive them to bite, or overpower the smells of our skin that helps mosquitoes find us.

    Diethytolumide (DEET) is a widely recommended ingredient in topical repellents. Picaridin and oil of lemon eucalyptus are also used and have been shown to be effective and safe.

    How do other products work?

    “Physical” insect-repelling products, such as wristbands, coils and candles, often contain a botanically derived chemical and are often marketed as being an alternative to DEET.

    However, studies have shown that devices such as candles containing citronella oil provide lower mosquito-bite prevention than topical repellents.

    A laboratory study in 2011 found wristbands infused with peppermint oil failed to provide full protection from mosquito bites.

    Even as topical repellent formulations applied to the skin, these botanically derived products have lower mosquito bite protection than recommended products such as those containing DEET, picaridin and oil of lemon eucalyptus.

    Wristbands infused with DEET have shown mixed results but may provide some bite protection or bite reduction. DEET-based wristbands or patches are not currently available in Australia.

    There is also a range of mosquito repellent coils, sticks, and other devices that release insecticides (for example, pyrethroids). These chemicals are primarily designed to kill or “knock down” mosquitoes rather than to simply keep them from biting us.

    What about stickers and patches?

    Although insect repellent patches and stickers have been available for many years, there has been a sudden surge in their marketing through social media. But there are very few scientific studies testing their efficacy.

    Our current understanding of the way insect repellents work would suggest these small stickers and patches offer little protection from mosquito bites.

    At best, they may reduce some bites in the way mosquito coils containing botanical products work. However, the passive release of chemicals from the patches and stickers is likely to be substantially lower than those from mosquito coils and other devices actively releasing chemicals.

    One study in 2013 found a sticker infused with oil of lemon eucalyptus “did not provide significant protection to volunteers”.

    Clothing impregnated with insecticides, such as permethrin, will assist in reducing mosquito bites but topical insect repellents are still recommended for exposed areas of skin.

    Take care when using these products

    The idea you can apply a sticker or patch to your clothing to protect you from mosquito bites may sound appealing, but these devices provide a false sense of security. There is no evidence they are an equally effective alternative to the topical repellents recommended by health authorities around the world. It only takes one bite from a mosquito to transmit the pathogens that result in serious disease.

    It is also worth noting that there are some health warnings and recommendations for their use required by Australian Pesticides and Veterinary Medicines Authority. Some of these products warn against application to the skin (recommending application to clothing only) and to keep products “out of reach of children”. This is a challenge if attached to young children’s clothing.

    Similar warnings are associated with most other topical and non-topical mosquito repellents. Always check the labels of these products for safe use recommendations.

    Are there any other practical alternatives?

    Topical insect repellents are safe and effective. Most can be used on children from 12 months of age and pose no health risks. Make sure you apply the repellent as a thin even coat on all exposed areas of skin.

    But you don’t need “tropical strength” repellents for short periods of time outdoors; a range of formulations with lower concentrations of repellent will work well for shorter trips outdoors. There are some repellents that don’t smell as strong (for example, children’s formulations, odourless formulations) or formulations that may be more pleasant to use (for example, pump pack sprays).

    Finally, you can always cover up. Loose-fitting long-sleeved shirts, long pants, and covered shoes will provide a physical barrier between you and mosquitoes on the hunt for your or your family’s blood this summer.The Conversation
