If You Drool While You Sleep, It May Be a Sign That…
Drooling during sleep is usually normal and doesn’t automatically mean something is wrong. It happens when saliva collects in your mouth and leaks out, often because you’re sleeping with your mouth open.
Possible reasons include:
Sleeping position: Side or stomach sleeping can make saliva more likely to escape.
Mouth breathing: A blocked nose, allergies, congestion, or enlarged tonsils can cause you to breathe through your mouth.
Acid reflux: Reflux can sometimes increase saliva production.
Certain medications: Some medicines can increase saliva production.
Sleep apnea: Loud snoring, gasping/choking during sleep, morning headaches, and excessive daytime sleepiness alongside drooling can warrant evaluation for sleep apnea. (mayoclinic.org

When to get checked
If drooling suddenly becomes much more frequent, is accompanied by difficulty swallowing, facial weakness, speech problems, or other neurological symptoms, seek medical attention promptly. Difficulty swallowing can also cause saliva to accumulate. (clevelandclinic.org)
So, occasional nighttime drooling usually isn’t a sign of a serious disease. If it happens regularly, especially with loud snoring or breathing pauses, it’s worth discussing with a healthcare professional.
