Mouth breathing while you sleep may seem harmless…but it can actually lead to a TON of health issues. And I don’t just mean bad breath. We’re talking about your WHOLE body.

There are a ton of reasons someone might be a mouth breather while they sleep. Allergies and congestion are a common reason. If your nose is stuffy and it’s tough to breathe with your mouth closed, you’ll be more likely to default to mouth-breathing. Alcohol is also a pretty big culprit, too. When you drink, the muscles in your throat relax and are more likely to cause you to snore, and that can contribute to your mouth opening. And then, your facial anatomy ALSO plays a role.

So in this video I'm going to walk through the dangers of mouth breathing, what causes it, and how to fix it!
