Scroll through any wellness feed today, and it will not take long to find someone taping their mouth shut before bed, promising viewers deeper sleep, reduced snoring, and a fresher morning face. The practice has become one of social media’s most talked-about sleep hacks. Yet behind the trend lies a more complicated clinical picture that is believed to deserve closer scrutiny before anyone reaches for a roll of tape. In an interview with Tezzbuzz Lifestyle, Dr Prasanna Kumar, HOD and consultant- respiratory medicine at Ramaiah Memorial Hospital, Bengaluru, separates facts from social media myths.

Understanding the trend

Dr Prasanna said, “Mouth taping is sealing the lips shut overnight with a strip of skin-safe adhesive tape, with the goal of forcing air through the nose instead of the mouth. And there is some logic behind it.” Nasal breathing genuinely does more for the body than most people realise. It filters out dust and allergens, warms the air, adds moisture before it reaches the lungs, and can even ease dry mouth or light snoring in someone who is otherwise healthy. So, the trend did not appear out of nowhere; it borrows from a real physiological principle.
