Is it normal to drool in your sleep?
Yep.Totally normal
Yes, drooling in your sleep is common and usually harmless. It often happens when your mouth relaxes open or you sleep on your side.
Yes—sleep drooling happens to plenty of people. Your face and jaw relax while you sleep, and if your mouth falls open, saliva can escape instead of being swallowed. Side sleeping can make it more noticeable, and a stuffy nose may lead you to breathe through your mouth.
It’s usually nothing to worry about, even if you occasionally wake up to a damp pillow. If drooling suddenly becomes heavy while you’re awake too, or you’re having trouble swallowing, that’s worth getting checked out.
