Let’s be clear here: Drooling while you sleep is typically not a health concern whatsoever. In fact, it is quite normal. It can be somewhat embarassing, however, particularly if you drool after having nodded off on a bus, airplane, or on your mother-in-law’s new couch. Drooling while you sleep can also indicate that perhaps there is something else going on with your health that you should be having checked out by a medical professional. These are some of the reasons why you might drool while sleeping, what you can do about it, and how to know when to see a doctor.
