Dr. Terkonda states "During sleep, with nasal breathing, the tongue and soft palate are less likely to fall back and obstruct the airway", there fore being less likely to snore.

Breathing through mouths when sleeping causes apneas (loud snoring and episodes of no breathing). As a result, nose breathing leads to improved sleep quality and less stress on the body.

As mouths are used for speaking and eating, the nose is purely for breathing which is the reason for having one. The benefits of nose breathing includes filtering air particles, humidification and adjusts air temperature before endering the lungs.

The nose helps the lung and throat to function better by providing warmer and moist air from the nose.

Mouth tape promotes nasal breathing, reducing mouth dryness and bacteria buildup, which helps prevent bad breath and teeth grinding.

Taping the mouth maintains nasal breathing which during exercises improves respiratory muscles, reduces irritation to airway and gives maximal oxygen intake.
