If you sleep on your stomach or side, gravity can release saliva more easily. People who sleep on their backs, on the other hand, swallow saliva more easily, which reduces saliva production.
Nasal Congestion
When your nose is blocked due to an allergy, cold, or sinusitis, you breathe more through your mouth, causing an uncontrolled flow of saliva.
Excessive Salivation
Some people produce more saliva than normal. This is called hypersalivation. This can be caused by oral infections, swollen tonsils, or reactions to certain foods and medications.
Gastroesophageal Reflux Disease
Heartburn can irritate the throat and lead to excessive saliva production. People with reflux often experience nighttime drooling and heartburn.
Neurological conditions
Some conditions, such as Parkinson’s disease, cerebral palsy, or stroke, can affect facial muscle control, making swallowing difficult and leading to excessive saliva production.
Medication use
Certain medications, such as tranquilizers, antipsychotics, and some antibiotics, can increase saliva production or relax the muscles in the mouth, causing you to drool at night.
