Proper Mouth Taping Technique - James Nestor

There are a lot of videos about this, and many of them have people taping their entire mouth shut. There are even products that are sold that cover the entire mouth with a small hole in the middle. However.... the way to do it properly, and safely, is with a tiny strip of medical tape about a half inch wide and just long enough to cover the very middle part of your lips. You should easily be able to breathe through the sides of your mouth.

The reason it works is that it simply reminds your body to hold your mouth shut during sleep so that you can nose-breathe instead of mouth breathe.
