Endorsed by celebrities like Gwyneth Paltrow and Julia Bradbury, mouth taping is using porous tape to cover your mouth and keep it closed during the night, with the view to promote nasal breathing, prevent bad breath, and help you sleep better.
Breathing in and out through your nose helps filter dust, pollen, and other particles from the air before they reach the lungs. It also helps moisten and warm the air, avoiding irritation. For this reason, many health experts consider nose breathing the ideal, and in taping your mouth shut, the idea is that you'll have to breathe through your nose.
