What drooling during sleep usually means
Drooling (called sleep drooling or sialorrhea) is common and usually harmless. It happens when saliva escapes the mouth because:
- You sleep with your mouth open

- You have nasal congestion (cold, allergies, sinus issues)
- You produce slightly more saliva (can happen with some foods or medications)
When it might need attention (less common)
In rare cases, excessive drooling during sleep can be linked to conditions affecting swallowing or muscle control, such as:
- Neurological disorders (for example, Parkinson’s disease)
- Certain nerve or muscle conditions
