“Do you wake up with a wet pillow? Find out why you drool in your sleep” (Page 2 ) | April 17, 2025

Sleeping Sleeping on your stomach or side facilitates the secretion of saliva thanks to gravity. In contrast, people who sleep on their back tend to swallow saliva more easily, which reduces its production. Nasal Congestion
When your nose is blocked due to allergies, a cold, or sinusitis, you breathe more through your mouth, which causes an uncontrolled flow of saliva.

Excessive saliva production
Some people produce more saliva than normal, a condition called hypersalivation. This can be caused by a mouth infection, swollen tonsils, or a reaction to certain foods or medications.
Gastroesophageal reflux disease (GERD)
can irritate the throat and stimulate excessive saliva production. People with reflux often complain of nighttime salivation and heartburn.

Neurological disorders
Certain conditions, such as Parkinson’s disease, cerebral palsy, or stroke, can affect the control of facial muscles, which can make swallowing difficult and cause excessive salivation.

Medication Use
Certain medications, such as sedatives, antipsychotics, and some antibiotics, can increase saliva production or relax mouth muscles, causing nighttime salivation.
