Mouth taping is as simple as it sounds - applying a line of tape on your mouth before going to sleep to encourage breathing out of your nose.
The hashtag mouth taping on TikTok has amassed more than 24.7 million views as countless influencers share how they started the home remedy to better their sleep.
Wellness influencer Move With James regularly posts about mouth taping to his 23.9k followers on TikTok, with his videos on the topic reaching millions of views.
He says he started mouth taping to help with his snoring and sore throat after waking up and feeling tired after eight hours of sleep.
“It has helped me reduce my snoring, relieve shoulder and neck tension, get better sleep, wake up without sore throat and nose-breathe better during the day,” he says in another video.
Influencer Cory Rodriguez, also known as Health With Cory, also backs the method, saying taping his mouth shut nightly helps improve oral health, humidify the air and eliminate snoring.
“You will have the best sleep of your entire life,” TikToker Isabelle Lux says in a viral video.
“I can no longer sleep without it ... please get actual mouth tape. It is so easy.”
Experts agree nose breathing is more beneficial than mouth breathing as it can help filter out dust and allergens, boost your oxygen uptake and humidify the air you breathe in.
Meanwhile, mouth breathing can dry out the mouth and increase the risk of bad breath and gum inflammation.
However, they say the benefits of mouth taping are largely anecdotal at this stage.
Medical experts are warning the home remedy will not solve the underlying medical issues that may be causing mouth breathing and snoring and could be dangerous.
“This is one of the most dangerous trends I’ve heard of in some time, and I’m quite concerned that it is being advocated as a ‘health’ trend,” US-based general practitioner David Culpepper told Fox News Digital.
“To put it quite simply, intentionally obstructing your airways during sleep is a terrible idea.
“Furthermore, if your nasal cavity becomes obstructed during the night because of a cold or allergies ... you could suffocate from not getting enough air.”
Baltimore Mercy Medical Centre primary care doctor Kathryn Boling agreed mouth taping was a terrible idea.
“There are a lot of TikTok (trends) I see where I am like, ‘goodness gracious, where do these things come from?’ ” she told USA Today.
Repeatedly taping lips could cause abrasions and cuts, Boling said.
It could have even more serious consequences, she warned, such as causing you to choke or suffocate on your own vomit if you throw up in the night.
