2. Digestive Issues
Acid reflux or heartburn at night can increase saliva production as your body tries to protect the throat. If you experience symptoms like coughing, a sour taste, or burning sensations while lying down, this could be contributing to drooling.
3. Oral Health Factors
Problems like gum inflammation, dental issues, or throat infections can temporarily trigger excess saliva. Once the irritation resolves, drooling usually decreases on its own.
In most cases, occasional drooling is harmless—especially if it’s been a lifelong habit, appears only during illness, or changes with your sleep position.
When to Seek Advice
Sudden drooling, persistent one-sided drooling, or difficulty swallowing should be checked by a healthcare professional. Noticing patterns and triggers can help you stay informed and ensure your overall well-being.
