About two thirds of Americans and Canadians, and I'm sure people over the world, sleep with their mouth open. And it's one of the most detrimental things to your recovery, your oral health. And. And it's such a simple, easy intervention. Just placing a piece of tape vertically on your mouth like this. You can still breathe through your mouth if you need to or want to. You can still talk if you need to. You don't have to seal your mouth like you see some people doing. It's just to keep your jaw relaxed and your mouth closed, to ensure that you're breathing through your nose throughout the night. And I think of that as a form of breath work. That's probably the easiest breath work that we can do, because we don't even have to think about it. We just have to put the tape on.
