When we sleep our facial muscles, as well as our swallowing reflexes, are totally relaxed. Since saliva gets accumulated in the mouth while we sleep, it can slowly start dripping because the relaxed facial muscles may lead to a slightly open mouth. Therefore, we end up having a wet pillow that’s not very comfortable to sleep on.
Excess drooling or hypersalivation can be a sign of a neurological disease or the result of nasal congestion. Also, people who already had issues with health, like a stroke, tend to drool more often and more excessively.
How to reduce or stop drooling?
1. Clear your sinuses.
