Viral trends can change our routines with surprising speed. One of them is mouth taping, a practice that involves sealing your mouth shut with adhesive tape before going to sleep in an attempt to breathe only through your nose.

On social media, it is presented as a simple way to rest better, reduce snoring, and wake up with more energy. However, just because a technique is popular does not mean it is safe or suitable for everyone.

What benefits does mouth taping promise?

Those who promote this practice claim that nasal breathing may improve mood, digestion, sleep, and oral health. Breathing through the nose serves important functions, but there is not enough evidence to attribute all of these benefits to using tape over the mouth.

Specialists also warn that breathing through the mouth at night may be the result of another issue. Nasal congestion, allergies, an anatomical abnormality, or obstructive sleep apnea are some examples. Taping your mouth shut does not identify or resolve these possible causes.

Risks of taping your mouth shut to sleep

Mouth taping may cause skin irritation, anxiety, a feeling of confinement, or difficulty breathing if your nose becomes blocked during the night. The risk deserves special attention if you have respiratory problems, severe congestion, or consume alcohol or sedative medications.

It would also not be a wise practice for people with gastroesophageal reflux, nausea, or other conditions that may make breathing more difficult or cause vomiting while they sleep. You should not try it on your own if you suspect you have sleep apnea.

If the main issue is a racing mind when you go to bed, taping your mouth will not address its root cause. In that case, this article on how to calm nighttime anxiety and sleep better may guide you.

Mouth taping and sleep apnea: what science has found

A 2022 study analyzed the effect of this technique in a small group of patients with mild obstructive sleep apnea who breathed through their mouths. The results showed a reduction in snoring and in some apnea episodes.

Even so, the study had important limitations. Only a small number of people took part, and no comprehensive evaluation of sleep quality was conducted. Therefore, these preliminary findings do not support recommending mouth taping as a general treatment.

Some professionals believe it could be studied as a complementary option in very specific cases of mild apnea. This would always require a prior medical assessment and appropriate follow-up. In some people, restricting oral breathing could make airflow more difficult and lead to a dangerous drop in oxygen levels.

What to do if you snore or breathe through your mouth

Frequent snoring, breathing pauses noticed by someone else, waking up feeling short of breath, dry mouth, and daytime sleepiness all warrant a professional consultation. Sleep apnea is common and often goes undiagnosed, but it can lead to complications if left untreated.

Depending on each case, recommendations may include sleeping on your side, avoiding alcohol close to bedtime, treating a nasal obstruction, or using a CPAP device. It is also helpful to take care of your sleep schedule and bedroom environment. To learn more, you can read these keys to achieving deep, restorative sleep.

Nasal breathing can be beneficial, but forcing it with adhesive tape is not a universal solution. If you need to open your mouth to breathe every night, it is better to investigate the cause than to hide the signal. A medical evaluation can help you find a safe alternative that is truly suited to what is happening to you. 🌙
