Reasons why you drool while sleeping and what it could mean

 

Have you ever woken up with a wet spot on your pillowcase? That tiny trickle of nighttime saliva can make you smile… or shudder, especially when you’re away from home. Should you be worried? Not necessarily. Although often harmless, this phenomenon can reveal some surprising truths about your health. What if your body is trying to send you a message during the night?

Sleeping with your mouth open: A habit to keep in mind

Do you sleep on your stomach or on your side? This is often the main reason for those “wet” nights. In the side position, gravity favors the flow of saliva, especially if your mouth is slightly open, a common occurrence in cases of nasal congestion (colds, seasonal allergies, etc.). Changing positions can improve the situation.

Medications and salivation: A little-known side effect

Some medications can increase saliva production, such as sedatives, antipsychotics, antibiotics, and even ibuprofen. This doesn’t mean you should stop taking the medication, but talking to your doctor can help you adjust your dosage or consider other, more tolerable options.

Sleep apnea, acid reflux, and ENT disorders: underlying causes

Excessive salivation can also be related to more complex conditions: sleep apnea, gastroesophageal reflux disease, and even a deviated nasal septum. These disorders promote oral breathing and, therefore, salivation. Concomitant symptoms can be a warning sign: snoring, persistent fatigue, or difficulty breathing at night. In these cases, it is advisable to consult a doctor specializing in sleep disorders. Therapies such as CPAP can offer significant improvement.

Teeth, pregnancy or deficiencies: unexpected factors

Dental conditions (cavities, gingivitis), pregnancy (salivation during pregnancy), or vitamin B12 deficiency can also cause excessive salivation. If the problem persists, a simple medical examination can help determine the cause.

Soft solutions… and other more specific solutions

Here are some tips for enjoying drier nights:

Sleeping on your back: It takes a little practice, but the results are quickly visible. Regular hydration, light meals at night, and a slice of lemon before bed (be careful with your tooth enamel).
Mouthguards and braces: For bruxism or mild sleep apnea.
Botox or surgery: Treatments are rare, but are sometimes offered in very specific cases.

When should you see a doctor?

If salivation becomes bothersome (wet pillow, mouth pain, heartburn, speech or sleep disturbances), a visit to the doctor is essential. A specialist can give you an accurate diagnosis and suggest a solution tailored to your situation.

Sleep is essential… even when it’s dry.
