By BLG - décembre 18, 2025

Waking up with a pillow soaked in drool is not only uncomfortable, it's also a mystery to many. Why do some people drool in their sleep, and what does this seemingly harmless phenomenon mean?

Nighttime drooling: a common phenomenon (1/12)

Nighttime drooling is a common phenomenon that can affect anyone, causing a damp pillow upon waking. Understanding the possible reasons for this excessive salivation is essential.

Sleeping position and nighttime drooling (2/12)

Sleeping position, especially sleeping on one's side or stomach, can promote nighttime drooling, especially if the nose is blocked, forcing one to breathe through the mouth.

Breathing problems and nighttime drooling (3/12)

Respiratory problems such as nasal congestion or sleep apnea syndrome can increase saliva production, exacerbating nighttime drooling.

Hypersalivation and its causes (4/12)

Hypersalivation can be caused by diet, hormonal changes in pregnant women, or gastroesophageal reflux, increasing saliva production.

Infections, allergies and nighttime drooling (5/12)

Respiratory infections and allergies can cause a stuffy nose, increasing the risk of nighttime drooling.

Medications, neurological disorders and nighttime drooling (6/12)

Certain medications and neurological disorders can cause excessive salivation, such as antipsychotics or Parkinson's disease.

Change position to reduce drooling (7/12)

Changing your sleeping position, especially sleeping on your back, can reduce nighttime drooling. Using a supportive pillow can make this transition easier.

Treating respiratory problems (8/12)

Treating breathing problems with decongestant sprays or antihistamines can help reduce nighttime drooling. A medical diagnosis is essential for sleep apnea.

Reducing excessive salivation during meals (9/12)

Avoiding spicy or acidic foods can reduce excessive salivation. Consulting a doctor for appropriate treatments for gastroesophageal reflux is advised.

Exercises for neurological disorders (10/12)

Orofacial exercises under medical supervision can improve muscle control for those suffering from neurological disorders, thus reducing drooling.

Medical solutions for severe hypersalivation (11/12)

In severe cases of hypersalivation, botulinum toxin injections or surgical interventions may be considered to reduce saliva production.

Consult a doctor for chronic drooling (12/12)

Consulting a doctor is crucial if nighttime drooling becomes chronic or interferes with quality of life, to identify the cause and choose the right treatment.
