Each of us sometimes wakes up to find drool on the pillow. This is called drooling, and it’s quite normal if it happens to you occasionally and in moderate amounts. However, if this happens regularly, it’s worth paying attention to.
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.
