10 Reasons You’re Drooling While You Sleep and What It Could Mean

Drooling while you sleep is generally not a cause for concern and is actually quite common. However, it can be a bit embarrassing, especially if it happens when you’re on public transport or at someone else’s house. In some cases, drooling can point to other health issues that might require attention from a healthcare professional. Here are some common reasons why you might drool during sleep and what it could mean.

1. Sleep Position

Your sleep position can play a big role in drooling. When you sleep on your side or stomach, excess saliva may escape from your mouth. If your nose is congested, you might sleep with your mouth open to breathe, making drooling more likely, especially during a cold or allergy flare-up.

2. Medication Side Effects

Certain medications, such as sedatives, antipsychotics, and some antibiotics, can cause drooling. Even over-the-counter medications like ibuprofen can sometimes have this effect. If this is a problem, talk to your doctor about alternatives or adjustments to your dosage.

3. Nasal Congestion

A stuffy nose can make it difficult to breathe through your nose, forcing you to sleep with your mouth open. This is common with colds or allergies. The drooling usually stops once the congestion clears up.

4. Deviated Septum

A deviated septum can block airflow through your nose, leading to mouth breathing and drooling. If this is the cause, your doctor may discuss surgery options.

5. Sleep Apnea

Sleep apnea, where your breathing pauses during sleep, can cause mouth breathing and drooling. If you also experience loud snoring or wake up feeling unrested, consult your doctor for treatment options.

6. Infection or Dental Issues

Oral infections, like cavities or gum disease, can increase saliva production, leading to drooling. If you notice pain or swelling, it’s best to visit your dentist.
