Doctors expose TikTok's mouth taping fad as unproven, risky, and medically unsafe
Popular among self-styled 'looksmaxxing' communities and wellness influencers, the practice involves sealing the lips shut during sleep to encourage nasal breathing.
Claims range from improved sleep and better oral health to enhanced jawline definition and anti-aging effects.
But researchers from the Lawson Research Institute, London Health Sciences Centre Research Institute (LHSCRI), and Western University's Schulich School of Medicine & Dentistry say these claims have no strong scientific basis.
They reviewed 86 studies on the subject and performed an in-depth analysis of 10 that included 213 patient experiences.
The conclusion: mouth taping does not deliver the health benefits influencers promise, and may actually worsen sleep-related breathing issues.
While social media content promotes mouth taping as a simple solution for a variety of sleep and cosmetic issues, the researchers found no robust evidence supporting any of these benefits.
The trend is being driven largely by non-experts, many of whom lack medical training. Dr. Brian Rotenberg, a researcher at Lawson, LHSCRI, and Schulich Medicine & Dentistry, noted that it was concerning to see celebrities and influencers endorsing mouth taping without scientific evidence.
He said, 'In the language of social media influencers, it seemed a bit 'sus,' so we examined what science is telling us about this trend and whether or not it is safe.'
The review found no meaningful improvements in sleep quality, oral hygiene, or physical appearance that could be directly linked to mouth taping.
In fact, most studies either showed no impact or highlighted potential complications.
The biggest concern from the researchers is the risk posed to people with undiagnosed sleep apnea, a condition where breathing repeatedly stops and starts during sleep.
Taping the mouth can block a crucial airway route, especially if the nose becomes congested. Rotenberg, who is also an otolaryngologist and sleep surgeon, emphasized that taping the mouth shut during sleep is dangerous, especially among those who may not be aware they have sleep apnea.
He said these individuals are unknowingly making their symptoms worse and putting themselves at greater risk for serious health complications like heart disease.
The rise of mouth taping is closely tied to online beauty and 'optimization' trends, where users chase physical perfection through extreme or unproven techniques.
Within the looksmaxxing community, a space focused on enhancing perceived attractiveness, mouth taping has been promoted as a way to fix the so-called 'mouth breather face' and sculpt a more defined jawline.
It's often discussed alongside practices like 'mewing,' which involves tongue posture exercises, and 'mogging,' which describes outshining others in looks or dominance.

These aesthetic claims have spread rapidly across platforms like TikTok and Reddit, even though they lack credible scientific validation.
The influence of viral trends often outpaces scientific scrutiny, creating a gap that misinformation easily fills.
People trying these hacks are often unaware of the physiological dangers involved, particularly when they interfere with something as critical as breathing.
The study's authors stressed the importance of making health decisions based on scientific research rather than social media fads.
The message from the medical community is clear: wellness trends should not come at the cost of breathing safely through the night.
The study is published in the journal PLOS One.

Is cereal good or bad for you? 11 best 'healthy' brands in Canada, ranked on sugar, fibre, protein and more
A dietitian says that regardless of healthiness, it's necessary to start your day by fuelling your body with food. If in the mad-dash morning rush you're managing to put any food in your stomach at all, registered dietitian Janine LaForte wants you to know you're doing all right. She knows breakfast is a challenge for those facing the consequences of the snooze button or racing against the arrival of the school bus. This stress, LaForte says, is particularly felt for families facing food insecurity, an interlocking barrier mounting up on top of regular morning hurley-burley. LaForte, who also owns Real Life Nutrition in Winnipeg, notes her personal ideal morning meal isn't breakfast cereal: 'It would be something like just an oatmeal, right? There's that one ingredient [and] you add in what you'd like.' This article is for informational purposes only and is not a substitute for professional medical advice, diagnosis or treatment. Contact a qualified medical professional before engaging in any physical activity, or making any changes to your diet, medication or lifestyle. However, she notes that cereal is an affordable, dependable choice to start the day for many: 'There are a lot of families who are struggling. And there's a lot of kids who don't want to eat breakfast. And cereal — and I will tell you, from my own personal experience — has been the go-to breakfast because it's quick. Kids are often rushing in the morning, and parents [are] as well.' Cereal, she says, is typically an easy, quick meal. 'If it's a matter of eating a bowl of cereal, even if it's something that you may deem not so 'healthy,' it's at least something that they're getting in before they go out the door. Or even as an adult goes out the door.' But with some cereals so laden with sugar that they border on candy, how can you make sure you're pouring yourself a bowl of goodness in those snatched A.M. moments? Here, LaForte guides us through what makes some cereals stack up better than others. Plus, keep scrolling for a nutritional comparison of some of the most popular 'healthy' cereal brands you can find in Canadian grocery stores. Fibre, sugar, balance: What to look for when shopping for cereal 'I think breakfast is a really good opportunity to get fibre in your diet,' LaForte says, adding that choosing higher-fibre cereal is an excellent starting point for a nutritious breakfast. Whole grains, of course, pack more fibre than their refined counterparts, so LaForte suggests checking ingredient lists to ensure what your cereal is made of. A 2015 study (the most recent stats available) from the American Journal of Clinical Nutrition shares LaForte's focus on fibre. It indicates that less than 25 per cent of Canadians age 19 and older get enough of the digestion-and-satiety-aiding nutrient daily. Making a bowl of cereal into a balanced meal with staying power also means topping the cereal with things like fruit, seeds, nuts or yogurt, LaForte adds. Think classic options like sliced bananas and blueberries, or even pumpkin seeds and Greek yogurt. She also adds that variety is the key to good nutrition, so switching up the toppings and the cereals themselves — say, trying one made from corn and then one made from wheat — helps ensure you're getting different nutrients into your overall diet. Then there's sugar, an ingredient LaForte says 'people tend to eat more [of] than they need to.' Comparing nutritional labels and going for the lower-sugar option is an effective method to make sure you're pouring a healthier bowl of cereal. But LaForte does note that since cereals are 'fortified with vitamins and minerals in Canada,' the sugary treats could be a source of nutrients for picky eaters and those facing food insecurity. While reducing added sugar where you can in your diet is an important part of healthy eating, so is ensuring that you're getting enough of key nutrients. Are popular 'healthy' cereal brands in Canada actually healthy? In the breakdown below, we've rounded up a variety of healthy cereals to see which ones are your best A.M. bet in terms of nutritional information per a one-cup serving — not including milk. It's worth mentioning that all of the cereals are sources of nutrients like potassium, calcium and iron, with a majority also having several vitamins. It turns out that Shredded Wheat is tough to beat with no sugar and a mere gram of fat alongside a high fibre and protein content. Müslix, meanwhile, packs more sugar and fat than you might expect. Fibre One, on the other hand, lives up to its name with a whopping 27 grams of fibre — just five grams less than an average adult woman needs daily. Shredded Wheat Original Calories: 180 Fat: 1 g Fibre: 6 g Sugar: 0 g Sodium: 0 g Protein: 5 g Fibre One Crunchy Original Calories: 140 Fat: 1 g Fibre: 27 g Sugar: 1 g Sodium: 220 mg Protein: 4 g Multi Grain Cheerios Calories: 120 Fat: 1 g Fibre: 2 g Sugar: 6 g Sodium: 160 mg Protein: 2 g Kellogg's Two Scoops Raisin Bran Calories: 180 Fat: 1 g Fibre: 7 g Sugar: 14 g Sodium: 170 mg Protein: 5 g Nature's Path Smart Bran Calories: 140 Fat: 2 g Fibre: 23 g Sugar: 11 g Sodium: 230 mg Protein: 5 g Nature's Path Multigrain Flakes Calories: 210 Fat: 2 g Fibre: 10 g Sugar: 8 g Sodium: 210 mg Protein: 6 g Kellogg's All-Bran Original Calories: 180 Fat: 3 g Fibre: 18 g Sugar: 10 g Sodium: 320 mg Protein: 8 g Kellogg's Vector Maple Flavour Calories: 160 Fat: 1 g Fibre: 3 g Sugar: 12 g Sodium: 160 mg Protein: 10 g Kashi GoActive Mixed Berry Crunch Calories: 290 Fat: 4.5 g Fibre: 14 g Sugar: 15 g Sodium: 85 mg Protein: 14 g Kashi GoActive Honey Almond Flax Crunch Calories: 300 Fat: 8 g Fibre: 15 g Sugar: 17 g Sodium: 230 mg Protein: 15 g Kellogg's Müslix Almond Raisin Calories: 240 Fat: 2.5 g Fibre: 7 g Sugar: 17 g Sodium: 150 mg Protein: 6 g In the end, no matter if you're eating Shredded Wheat or Coco Puffs, LaForte touts the importance of starting your day with breakfast: 'Food is the fuel for our bodies. If you want to be able to function and do your best during your day, you need to fuel your brain. 'Some people don't like eating breakfast. However, if you can get something in, anything — a yogurt, some fruit, a balanced breakfast is the best. But if you can just get something in within an hour of waking up, that's going to be the best for your body.'

Weighted Vests Are Now A Fitness Trend. Here's What You Need To Know
Should you get this on your chest as opposed to off it? You may have seen people wearing what are called 'weighted vests' while walking on hiking trails, treadmills or TikTok for that matter. These weighted vests kind of look like space-age versions of sweater vests but instead of ridicule they hold weights. The argument is that wearing such a vest can help build muscle and bone strength and endurance as well as help you burn more calories. In fact, some social media influencers have acted as if wearing weighted vests while walking is 'rucking' amazing. But before I weighed in on the matter, I decided to try a weighted vest workout myself. How Weighted Vests Are Being Incorporated Into Workouts I went to an Equinox Club in New York City to experience their 'Fully Vested' workout. You may have heard of the term 'rucking,' which as I indicated in Forbes a couple years ago has become quite popular on social media. If you are wondering where the ruck this term came from, it originated from a 'ruck march,' which is military term for a very brisk walk over rough terrain while wearing a rucksack. A rucksack is a backpack but larger with more compartments. Well, people have been using the word 'rucking' to represent any type of walk while wearing any type of weights. David Silk, who is the program and content director of Precision Running at Equinox and the author of the Ultimate Treadmill Workout, has developed a treadmill workouts with a weighted vest that fulfills this popular definition of rucking but is hesitant to use this term to describe this workout. He told me that he wants to respect the original military term. Instead, he calls his program 'Fully Vested' in part because it involves you wearing a weighted vest fully on your chest while walking on a treadmill. He told me that, 'Wearing the vest can result in a 10 to 15 percent increase in calories burned.' The first step was to put on what's called a Precision Vest, precisely because it can be adjusted to match your size, shape and desired weight. To adjust the last thing, the vest included a number of weight pockets. Each weight pocket allowed you to insert a 2.5 pound weight brick (a Micro Kettle Bell) and thus control how heavy you want to make the vest. Each pocket had a magnet that could keep the pocket closed so that you wouldn't throwing your weights around, so to speak. The vest also was comprised partly of memory foam for comfort and adjustable for different body sizes and shapes. Silk walked me through—or rather I walked through while he explained—a 25-minute segment of the workout on a treadmill. This included changes in the speed of my walking and the incline that I faced. He said that the workout could also include 'Fly segments,' where you'd strip off the vest and then start running, more like what you would do in his standard Precision Run class. Silk talked about how, 'You then feel very light and fast. It decompresses your body after it's been loaded.' I sort of went fly bye for this particular workout and stuck with wearing the weighted vest throughout. The Fly segment doesn't have to be part of the Fully Vested workout for anyone. In fact, the speeds and inclines that you go through and the weights that you carry or don't carry can be tailored to your needs, hence the concept of a precision workout. Silk described how the Fully Vested workout was being soft-launched at certain Equinox clubs to gather info to then adjust the program before a full launch. He said then regarding weighted vest use in general, 'I am seeing more posts and stories of people sharing their experience.' He said, 'What has been an emerging trend is now an accelerating trend.' Weighted Vests Could Help You Burn More Calories And Build Endurance One of the potential benefits of wearing a weighted vest while walking or doing other activities is what Silk mentioned, burning more calories. In theory, if you are increasing the effort needed, your body will need to expend more energy. Of course, the calories you burn will depend on the activity that you are doing, your own metabolism, the amount of weight you are carrying and other conditions. So, fittingly, there can't be a one-size-fits-all expectation when it comes to weighted vests and calorie burning. A similar situation applies to endurance. Since carrying more weight could make your walking or workouts harder, it could also help further build the endurance that you are trying to build. Again, how much more endurance you build depends on a many different factors. Weighted Vests Could Potential Help Build More Muscle Strength When you think lifting and carrying weight, you must think muscles as well. A weighted vest in theory should increase the work that your muscles do when walking. This should include the muscles that help you walk, including all those in your lower extremities, and the ones that keep you upright, such as you abs and glutes. If you are still harboring hopes of winning those Mr. or Ms. Olympia body-building contest, keep in mind that you start progressively losing muscle mass in your 30s, which means you have to progressively work harder at keeping up your muscles. Your muscles also play important roles in protecting your joints and in the case of your core muscles your spine from injury. To date, there have'n't been enough good quality scientific studies to tell exactly how much muscle strength a weighted vest will help build. Plus, the impact of the weighted vest likely depends on a number of factors such as your current muscle mass, the size and shape of your body, the type and intensity of the workout, the weight of the vest and the surrounding conditions like whether they are playing the Karate Kid movie song 'You're the Best' in the background. So, it is difficult to tell how a weighted vest workout might compare to other muscle building workouts. The answer may be different for different people, hence the 'p' word, meaning precision. Weighted Vests Could Potentially Help With Bone Health Then there are the skele-ton of other possibilities, that using weighted vests could help strengthen your bones or at least keep them strong. The evidence, though, for this is not yet super strong. But more on that later. To understand how weight-bearing could help your bones, you have to understand how your bones work. They aren't just static entities but instead are continuously undergoing bone formation and bone breakdown. In the earlier part of your life up to your mid-20s, the rate of bone formation typically exceeds the rate of bone breakdown, so that your bone density continues to increase over time. All of this changes around the age that you are finally able to join the Pony Club in the U.K., meaning when you are 25 years of age. After then, the rates of bone formation and breakdown tend to stay relatively equal so that your bone density remains relatively the same for a couple decades. Things change again around age 50, though, when the rate bone breakdown usually begins to exceed that of bone formation. This can mean a progressive loss in bone density over time. When your bone density drops below what's considered normal for your age, it's classified as osteopenia. Consider this a step before having osteoporosis. The lower your bone density in general, the more at risk you are for fractures throughout your body. If you start off with smaller and less dense bones, you may have less reserve when you start to lose bone density. Plus, going through menopause and the corresponding drop in estrogen levels can further accelerate bone loss as estrogen has a protective effect on your bones. All of this is why many training programs encourage weight-bearing and resistance exercises at any age. Such exercises can put appropriate amounts of stress on the bones—tolerable stress that will lead to some bone material breakdown that's followed by the bone material being built back up so that it's stronger and not intolerable stress that leads to fractures or your bones curling up in the corner and saying, 'I'm not worthy.' Therefore, in theory, a weighted vest could provide such 'good stress' to your bones like those comprising your spine, hips and lower extremities. A number of studies have supported the use of weight-bearing and resistance training in general to prevent bone loss and promote bone health. However, one may have a bone to pick about the studies on weighted vests specifically. For example, one study published in the Journal of Orthopaedic & Sports Physical Therapy and another published in the The Journals of Gerontology: Series A did show promising results among post-menopausal women, suggesting that incorporating weighted vests into exercise programs was associated with less bone loss. However, these studies had relatively small numbers of participants. Another relatively small study of women from 30 to 60 years of age published in the Journal of the Medical Association of Thailand found no difference among those who wore weighted vests while walking versus those who didn't. The Risks Of Weighted Vests Ultimately, your choice of workouts should be a balance between what the potential benefits may be, whether you will actually do the workout and hwo risky the workout may be specifically for you. A weighted vest isn't the type of thing that will get others to say, 'OMG, how brave of you to try that.' You should be careful if you do have some kind of injury in any part of your body that may be affected by the vest, particularly your neck, shoulders or back. It's also better to play it safe and check with your doctor first if you lower bone density or some kind of muscle problem. Of course, the risks can depend heavily on the type of weighted vest that you are using. You don't want to just strap a bunch of barbells to a cashmere sweater vest and call it a weighted vest. Stick to a vest that's been specifically designed and tested for the workout that you will be engaging in and make sure that the vest truly fits you. Make sure that the weight in the vest is properly balanced as well. You shouldn't feel like the Leaning Tower of Pisa while walking. Should you want to try the weighted vest thing, think of the Eagles song and take it easy from the start. Be conservative about how much weight you want to carry. Remember what may seem like no big deal at the beginning of a workout may not be that way in the middle of or even later in the workout. You can always gradually up your weight over the next bunch of workouts if you are aiming to weighted vest trash talk at your next cocktail party. Stick to activities that are already part of an established and recommended weighted vest workout program. That certainly includes walking and walking on a treadmill. But you may not want to be playing weighted vest basketball or dancing weighted vest Oppan Gangnam Style just yet without proper guidance from a health professional. Keep in mind that while a properly fitting weighted should give you a fair amount of freedom of movement, you can't just do anything that you would do without wearing a weighted vest. Be particularly mindful of maintain balance of your body. Be very careful when bending or leaning over. Use the same precautions that would if you were carrying something such as bending your knees and firing your abs. Weighted vests do give you an other way to vary and enhance your workout. They certainly seem increasing in popualrity right now. One market report estimated the size of weighted vest market to be $205 Million in 2024 and expects this to grow to $350 million by 2033. However, when deciding how you should work out, remember to 'p'— meaning use precision. You've got to do what works for you specifically. That includes choosing a workouts that you are more likely to complete, ones that your are fully-vested-in to continue. And that may or may not include a weighted vest.

I'm in my 60s — I put this $13 'Botox in a bottle' from a Canadian brand to the test
Shoppers are obsessed with this affordable anti-aging product. But does it live up to the hype? Aging is a natural part of life, but if you're not so into fine lines and wrinkles, you might want to check out The Ordinary's Argireline Solution 10% Serum for Facial Wrinkles. The Canadian company's serum has been dubbed "Botox in a bottle" by shoppers, and the best part? It's super affordable, ringing in at under $15. The brand's website categorizes it as a "non-injective solution for dynamic lines" specifically designed to target signs of aging. The serum almost seems too good to be true, so both my mom — who's in her 60s — and I decided to put it to the test to see if it lives up to the claims. Scroll down for our honest review. The Ordinary Argireline Solution 10% Serum for Facial Wrinkles review: What is it and what are the claims? The Ordinary's Argireline Solution serum is formulated to target skincare concerns such as fine lines and wrinkles, thanks to an Argireline Peptide Complex. As outlined on Sephora, this complex allegedly helps improve the overall appearance of the eye area and forehead, which are two prominent spots on the face that are most prone to creasing or developing folds in the skin. This affordable serum also features a lightweight texture. For best results, it's recommended to apply a few drops to the forehead and around the eye area twice a day. As The Ordinary's website suggests, you can incorporate this product into your routine after cleansing and before applying any anhydrous serums, oils, suspensions, or creams. also recommends avoiding the use of products featuring Direct acids, Direct/Ethylated Vitamin C, and Resveratrol 3% + Ferulic Acid 3% in the same skincare regimen as The Ordinary's Argireline Solution contains Peptides. First impressions As someone in her 60s, my mom is always on the hunt for new products to help target fine lines and wrinkles, so she was excited to give The Ordinary's Argireline Solution a go. This was her skin in the morning before she applied the serum — right after cleansing. She then applied a few drops of the Argireline Solution to her forehead and around the eye area, as recommended. Although she didn't notice a drastic physical change, my mom did note that the product felt tightening upon application, firming her skin after use. Best of beauty: I'm a dermatologist — 3 'universal' skincare staples I always recommend for anti-aging Cheekbone Beauty is Canadian, Indigenous-owned and sustainable — and these celebrities are 'adamant' about using it I'm a celebrity esthetician — this is the 'gold standard' for anti-aging Then, it was my turn. As a 27-year-old, I have always been curious about elevating my skincare routine and have become increasingly interested in finding preventative products that can reduce the look of fine lines as I age. As a result, I was eager to put The Ordinary's Argireline Solution to the test to see if it would actually work on both young and mature skin. Similarly to my mom, I applied a few drops of the lightweight serum to my forehead and eye area after cleansing. I, too, immediately noticed a tightening sensation after application but no immediate physical results- except for my skin appearing to look slightly smoother. It's important to note that it is recommended to use this product twice daily, so we will likely see improved results through more consistent use. What shoppers are saying This affordable serum has a 4-star rating on Sephora, based on more than 400 customer reviews. "Love this product," raved one shopper who deemed it "a staple" for them. "I'm on my third bottle," they added. One 72-year-old customer who has "spent thousands on expensive products" said, "I believe I found the holy [grail with] this stuff!" They said that after "a few weeks," their "fine lines have lessened," and their "deeper lines have softened" — even their "neck wrinkles." However, other shoppers claimed to have not seen any "noticeable improvements" after use, alleging that the product does not minimize the appearance of wrinkles as claimed. Is it worth it? It's worth noting that some skincare solutions take a couple of weeks to perform, so we decided to consistently use this product day and night, as recommended, to see if it garners any notable results. Consistency seems to be key when it comes to The Ordinary's Argireline Solution, as verified by other Sephora shoppers who have used and loved the product. Here's what we noticed after diligently using The Ordinary's Argireline Solution day and night for the past two weeks: Although my mom didn't notice a significant physical difference in her appearance, she did note that her skin felt smoother. For the price, she found that The Ordinary's Argireline Solution was definitely worth a try, and she will continue to use the product to monitor how her skin looks over time. After two weeks of consistent use, I, too, didn't notice a huge difference in the way my skin looked. However, I don't have excessive fine lines or wrinkles, so I may consider this to be more of a preventative skincare product in my everyday beauty routine. That said, I did appreciate how smooth my skin felt after use. I agree that this product is worth the hype in terms of the price tag if you're looking for an affordable way to improve skin smoothness and firmness. Even though it truthfully may be too early to claim that this product is "Botox in a bottle," our opinions may change after more consistent use, so we recommend giving it a fair shot (no pun intended) if you're looking to try it out yourself — especially for $13.
