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

Reasons Drooling Happens 

The body normally produces more than 1 liter of saliva per day. It is produced by salivary glands and is usually swallowed and re-circulated via the bloodstream. Drooling occurs when the saliva collects within the mouth and rather than being swallowed, it drips or runs out past the lips. Why might this occur more at night?

Excessive Salivation

In addition, excessive salivation (sialorrhea) may occur due to the use of medications or other medical conditions. It may be associated with difficulty swallowing that occurs secondary to a brain injury, stroke, or even Parkinson’s disease.
