Waking up with a wet pillow now and then is common and usually harmless. However, if drooling during sleep becomes a regular occurrence, especially after age 60, it may be worth paying attention to. While often nothing to worry about, persistent drooling can sometimes signal an underlying condition that needs attention. Here are eight possible causes.
1. Allergies or Nasal Congestion
When your nose is blocked, you naturally breathe through your mouth, which can lead to drooling. Seasonal allergies, colds, or sinus issues are common culprits.
What to do: Treat the underlying congestion with a humidifier, saline spray, or an antihistamine after consulting your doctor.
2. Sleep Apnea
Sleep apnea causes pauses in breathing during sleep, often leading to mouth breathing and drooling. Other signs include loud snoring, gasping for air, and daytime fatigue.
What to do: If you suspect sleep apnea, talk to your doctor about a sleep study. Treatment can improve both your sleep and your overall health.
3. GERD (Acid Reflux)
When you sleep, acid can travel up from your stomach into your throat, triggering excess saliva production. This can lead to drooling and a sour taste in your mouth in the morning.
What to do: Avoid eating heavy meals close to bedtime, elevate your head while sleeping, and talk to your doctor about reflux management.
4. Medication Side Effects
Many medications, especially sedatives, muscle relaxants, and some antidepressants, can cause excess saliva or difficulty swallowing during sleep.
What to do: Review your medications with your doctor. Do not stop any medication without professional guidance.
5. Stroke or Neurological Conditions
Difficulty swallowing (dysphagia) can cause drooling. This can be a symptom of a past stroke, Parkinson’s disease, or other neurological conditions.
What to do: If drooling is accompanied by other symptoms like slurred speech, weakness on one side, or facial drooping, seek immediate medical attention.
6. Sinus Infection
A sinus infection can lead to post-nasal drip and difficulty breathing through your nose. This can cause mouth breathing and drooling during sleep.
What to do: If you have facial pain, pressure, or thick nasal discharge, see your doctor for treatment.
7. Enlarged Tonsils or Adenoids
In some people, enlarged tonsils or adenoids can obstruct the airway during sleep, leading to mouth breathing and drooling.
What to do: An ear, nose, and throat (ENT) specialist can evaluate you and recommend treatment if needed.
8. Dental Issues or Ill-Fitting Dentures
Problems with your teeth or dentures can make it difficult to keep your mouth closed while you sleep, leading to drooling.
What to do: Visit your dentist to check for any issues that may be affecting your bite or oral comfort.
When to See a Doctor
You should consult your doctor if:
- The drooling is new or has become more frequent
- It is accompanied by other symptoms like choking, coughing, or difficulty swallowing
- You have other signs like facial weakness, slurred speech, or memory problems
- Your sleep partner notices you gasping or choking during the night
A Gentle Reminder
Most causes of drooling during sleep are harmless and treatable. But your body uses sleep to rest and repair itself. If something is disrupting that process, it is worth a conversation with your doctor. A simple change could lead to better sleep and better health.
