You may not realize that you’re breathing through your mouth instead of your nose, especially while you sleep. People who breathe through their mouth at night may have the following symptoms:

snoring dry mouth bad breath (halitosis) hoarseness waking up tired and irritable chronic fatigue brain fog dark circles under the eyes

Legionaries disease.

Just saying.

Does anyone else use "Mouth-Breather" as an insult or is that just me?
