TikTok Health Trends Ranked: From Mouth Taping to Parasite Cleanses

Mouth Taping for Better Sleep

Mouth taping is one of the most popular sleep hacks to go viral, with countless videos showing people taping their mouths shut to force nasal breathing during the night. The underlying theory is that nasal breathing is superior to mouth breathing, as it filters, warms, and humidifies the air, potentially leading to better oxygen absorption, reduced snoring, and improved sleep quality. While some small, preliminary studies have shown that mouth taping can reduce snoring in mild cases, there is a distinct lack of large-scale, peer-reviewed evidence to support its widespread use for the general population. The risks, however, are very real and should not be ignored. For individuals with undiagnosed or untreated sleep apnea, or those with chronic nasal congestion due to allergies or a deviated septum, mouth taping is an extremely dangerous practice. It can lead to dangerously restricted airflow, increased carbon dioxide levels, and in severe cases, a feeling of suffocation that could be fatal. A sudden bout of nausea or an urge to vomit while taped could also lead to a dangerous situation. While the concept of promoting nasal breathing has a scientific basis, the method of mouth taping is a cautionary trend that is not supported by a consensus of medical professionals and is particularly unsafe without first consulting a doctor.

Ice Baths for Recovery

Cold plunging has moved from the locker room of professional athletes to the forefront of wellness culture on social media. The claim is that plunging into freezing water reduces muscle soreness, speeds up recovery after exercise, and even improves mental resilience. The scientific evidence behind cold immersion therapy is significant, but it comes with important caveats. An ice bath causes vasoconstriction, or the narrowing of blood vessels, which can help flush out inflammatory byproducts that cause muscle soreness. Numerous meta-analyses and studies have shown that cold water immersion can modestly reduce delayed-onset muscle soreness (DOMS) after a strenuous workout, making it a legitimate recovery tool for athletes or people in a competitive training cycle. The purported mental health benefits are also gaining traction, with some research suggesting that the controlled stress of cold exposure can improve a person’s ability to cope with other stressors in life. However, these benefits do not come without risk. The initial shock of cold water can cause a rapid increase in heart rate and blood pressure, known as the cold shock response, which can be dangerous for people with cardiovascular issues. Prolonged exposure can also lead to hypothermia and even death. The scientific consensus is that ice baths can be a helpful recovery tool, but they are not a miracle cure and should be done with extreme caution, often with supervision, and are not necessary for the average gym-goer.

‘Parasite Cleanses’

Perhaps the most alarming and unscientific of the viral trends is the “parasite cleanse.” The claim, often made by non-medical influencers selling their own herbal products, is that everyone has hidden intestinal parasites that are causing a host of symptoms, from bloating to fatigue and chronic illness. They promise that a specific blend of herbs will “flush out” these worms. The scientific reality is that intestinal parasites are very rare in developed countries with good sanitation and clean water supplies. Furthermore, medical diagnosis of a parasite infection is not done with a supplement; it requires a doctor’s visit and specific stool or blood tests. The “parasites” that people claim to see in their stool after a cleanse are almost always undigested food, fiber, or threads of intestinal mucus that have been sloughed off by the harsh laxatives in the herbal products. The harm from these cleanses is very real. The unregulated herbal concoctions can contain dangerous ingredients and high doses of powerful laxatives, which can lead to severe abdominal cramps, chronic diarrhea, and serious dehydration. This dehydration, in turn, can cause a dangerous imbalance of electrolytes, which can affect heart function. The verdict is clear: “parasite cleanses” are a harmful and completely unnecessary myth. No medical professional or public health organization recommends routine cleansing, and anyone who suspects they have a parasite should seek medical attention, not a supplement from an influencer.

How to Judge Any Viral Health Hack

In an age where medical information is democratized but also unregulated, it’s crucial to develop a framework for evaluating any health hack you see on social media. Before you try a new trend, ask yourself these three critical questions:

1. Is there peer-reviewed research to support it?

   The gold standard of medical science is a randomized controlled trial published in a reputable, peer-reviewed journal. A TikTok video showing a person’s anecdotal experience is not evidence. Look for large-scale studies and meta-analyses, not a single small study or a company-sponsored trial. A quick search on Google Scholar or PubMed can often reveal a lack of credible research behind a popular claim.

2. What are the potential harms?

   Every medical intervention has a risk-benefit analysis. A common trend may seem harmless, but it could have dangerous side effects, especially if you have an underlying condition you aren’t aware of. Be cautious of any hack that promotes extreme behavior, promises a “cure-all,” or involves a product that is not regulated by a medical body.

3. Would a doctor or a certified health professional recommend it?

   Your doctor has years of training and access to your full medical history. A trend that works for a healthy young person on the internet might be dangerous for you. If a hack seems too good to be true and isn’t something your doctor would suggest, it’s probably best to skip it.

Trust Science Over Trends

TikTok is a powerful platform for creativity and connection, but it is not a substitute for medical science. The health hacks that go viral often fall into one of three categories: they are either evidence-based with important caveats (like ice baths), unproven and potentially dangerous (like mouth taping), or outright harmful myths (like parasite cleanses). When it comes to your health and wellness, the most important hack is to be a critical consumer of information.
