Do you drool while sleeping? Check out these ways to stop it

Nasal Congestion

One of the biggest reasons your mouth could come open at night is because you can’t breathe well through your nose. We are meant to breathe through our nose, but if congestion is present, our default option is to breathe through the mouth. If this occurs in sleep, saliva may drool onto our pillow.Nasal congestion may occur with a cold or secondary to allergies like hay fever. In addition, a deviated nasal septum may block the nose and contribute to mouth breathing. As a result of this obstruction, both snoring and sleep apnea may be associated with drooling.1
