Waking up with a pillow wet from saliva is actually pretty common and usually not a cause for alarm. Here’s what it can mean:
Possible Reasons
Mouth Breathing During Sleep
If your nose is congested or blocked, you may breathe through your mouth while sleeping. This can cause drooling, especially if your mouth stays open.
Sleeping Position
Sleeping on your side or stomach can make it easier for saliva to escape your mouth.
Relaxed Muscles
