Waking up to a damp pillow?
You’re not alone.
Drooling during sleep is more common than you think — and in most cases, it’s nothing to worry about.
Your body produces 2–4 pints of saliva daily, and sometimes, especially when you're deeply relaxed, it escapes while you sleep.
But if you're consistently soaking your pillow, it might be worth understanding why — and whether it’s a sign of something more.
Let’s explore the real reasons behind nighttime drooling — and when it might be time to talk to your doctor.
🧠 Why Do We Drool While Sleeping?
Saliva helps with:
- Digestion
- Oral health
- Preventing dry mouth
During sleep, your swallowing reflex slows, and your mouth may stay open — especially if you sleep on your side or stomach.
This can lead to saliva pooling and leaking out — especially if:
- You have nasal congestion
- You breathe through your mouth
- Your sleep posture encourages jaw relaxation
✅ In most cases, it’s just anatomy and habit — not disease.
