What are the benefits of mouth taping?

Mouth taping may encourage nasal breathing, reduce snoring and minor sleep apnea, and prevent dry mouth that can prompt nighttime awakenings to drink and then urinate.

• Oxygen and carbon dioxide: Nasal breathing during sleep is described as increasing oxygen brought into the system and carbon dioxide released; breath-holding during sleep can cause carbon dioxide buildup. 1
• Breath-holding and hormones: By supporting nasal breathing and reducing apnea, mouth taping may help limit sleep breath-holding associated with elevated cortisol and disrupted testosterone and estrogen levels. 2
• Snoring and minor sleep apnea: Mouth taping is presented as a way to shift toward nasal breathing, which may reduce snoring and offset sleep apnea when it is not severe. 3
• Dry mouth and nighttime trips: Mouth taping may reduce mouth-breathing-related dry mouth, so a person is less likely to wake to drink water and then need to urinate. 4
