The Role of Saliva in the Body
Before diving into the reasons why saliva might escape during sleep, it’s important to understand its significance in the body. Saliva is primarily produced by the salivary glands and serves many purposes:
- Digestive Aid: Saliva contains enzymes that start the breakdown of food in the mouth, making it easier for the stomach and intestines to process nutrients.
- Oral Health: It helps to rinse away food particles, prevent bacterial growth, and maintain a balanced pH level in the mouth, important for preventing tooth decay and gum disease.
- Speech and Taste: Saliva facilitates speaking and enhances the ability to taste by keeping the mouth moist.

Understanding Nocturnal Drooling
Why saliva coming out while sleeping according to science can be attributed to several factors, including:
1. Posture and Gravity
During sleep, the muscles in the mouth and throat relax, causing the jaw to drop open slightly. This change in posture, combined with gravity, can allow saliva to pool in the mouth and trickle out, especially if the person sleeps on their side or stomach.
2. Increased Saliva Production
At night, the body may produce more saliva than during waking hours. This phenomenon, known as nocturnal hypersalivation, can occur due to various reasons such as certain medications, pregnancy, or underlying medical conditions like gastroesophageal reflux disease (GERD).

3. Sleeping Conditions
If you sleep in a way that makes it hard to swallow normally, like lying flat on your back, saliva can gather in your mouth. Also, if you breathe through your mouth because of a stuffy nose or other blockages, it can make the problem worse.

4. Age and Health Factors
According to research by N Cocks · 2022, young children and elderly adults tend to drool more at night because their muscles are not as strong or coordinated. Conditions like Parkinson’s disease or having a stroke can also affect how well muscles work, making it easier for saliva to come out while sleeping.
Remedies and Prevention
It’s usually not a big deal if you drool a little while sleeping now and then, but if it happens a lot every night, it might be worth checking out. Here are some ways to manage why saliva coming out while sleeping according to science:
- Sleep Positioning: Encourage sleeping on the side to reduce the likelihood of saliva pooling.
- Oral Hygiene: Maintain good oral hygiene practices, including regular brushing, flossing, and using mouthwash to minimize bacterial growth.
- Addressing Nasal Congestion: Treat nasal congestion or allergies that may cause mouth breathing during sleep.
- Consultation with Healthcare Provider: If drooling is excessive or accompanied by other symptoms, consult a healthcare provider to rule out underlying medical conditions or medication side effects.
