Please don’t tape your mouth at night, whatever TikTok says. A new study shows why this viral trend can be risky

Mouth taping while sleeping has gained popularity as a method to improve sleep and overall health, with many supporters claiming it enhances airflow and reduces snoring. However, recent research suggests that while there may be limited benefits to mouth taping, it could also pose risks, especially for individuals with nasal blockages. Obstructive sleep apnoea, a condition where the airway is obstructed during sleep, was a key focus of the study, revealing only modest improvements in oxygen levels and apnoea frequency from mouth taping. Furthermore, there were concerns about potential harm, such as asphyxiation, for those with nasal obstructions. Therefore, experts do not recommend mouth taping as a solution for sleep issues, and it is crucial to seek advice from healthcare professionals for proper diagnosis and treatment.
