Drooling during sleep is common and usually harmless. However, it can sometimes indicate underlying issues. Here are some common causes:
1. Muscle Relaxation: During deep sleep, muscles, including those in the mouth and jaw, relax, causing the mouth to open and saliva to escape.
2. Sleeping Position: Sleeping on your stomach or side makes it easier for saliva to escape, while back sleepers tend to swallow more easily.
3. Nasal Congestion: When you’re congested, mouth breathing can lead to drooling.
4. Excess Saliva Production: Hypersalivation can be caused by oral infections, swollen tonsils, or certain foods and medications.
5. Gastroesophageal Reflux Disease (GERD): Acid reflux can trigger excess saliva production.
6. Neurological Disorders: Conditions like Parkinson’s or strokes may affect swallowing.
When to Seek Help: If drooling is frequent, excessive, or accompanied by other symptoms like trouble swallowing or breathing problems, consult a doctor.
