Why Do You Slobber in Your Sleep?
- Deep Sleep Muscle Relaxation: According to the Sleep Foundation, during deep REM sleep, your body enters a temporary state of paralysis. Your facial and swallowing muscles completely relax, allowing saliva to pool in your mouth instead of being swallowed automatically.
- Sleeping Position: If you sleep on your side or stomach, gravity takes over and pulls that pooled saliva straight onto your sheets.
- Mouth Breathing: Nasal congestion from allergies, colds, or a deviated septum forces you to breathe through your mouth. When your mouth stays propped open all night, drool is almost guaranteed.
For others, acid reflux (GERD) or certain medications can also trigger excess saliva, leaving them searching for ways on how to stop slobbering in sleep.
How to Prevent and Stop Slobbering in Your Sleep
The good news is that you don't have to live with soggy pillows forever. By making a few minor adjustments to your daily habits and bedroom environment, you can significantly reduce or completely eliminate nighttime saliva leaks. Here are the best natural tips on how to stop slobbering in your sleep:
1. Switch to Back Sleeping
This is the single most effective hack for dry mornings. When you sleep on your side or stomach, gravity works against you, channeling saliva directly out of your lips. By training yourself to sleep flat on your back, gravity forces any excess saliva to slide down the back of your throat, triggering your body’s natural swallowing reflex.
2. Clear Your Nasal Passages
If your nose is stuffed up, you have no choice but to breathe through your mouth. To keep your airways clear, try using a drug-free saline nasal spray or a neti pot before bedtime. Running a cool-mist humidifier in your bedroom can also prevent your sinuses from drying out and swelling, which is a major win if you want to know how to prevent drooling in sleep during dry winter months.
3. Stay Hydrated Throughout the Day
It sounds counterintuitive, but drinking enough water actually helps curb drooling. When your body is dehydrated, your salivary glands panic and start producing thick, sticky saliva that is much harder to swallow. Drinking water consistently during the day keeps your saliva thin and easy to manage.
Use a Supportive, Adjustable Pillow to Keep Your Mouth Closed
A supportive pillow keeps your neck aligned and your airways open. A contoured memory foam pillow, like the Newentor pillow, is designed to cradle your head and neck perfectly.

What makes the Newentor pillow a lifesaver for droolers is its adjustable height feature. We all have different shoulder widths and sleeping styles. With an adjustable pillow, you can add or remove layers to find your perfect loft.
- If it’s too low: Your head tilts back, your mouth hangs open, and saliva pools.
- If it’s too high: Your neck bends awkwardly, blocking your breathing.
- The sweet spot: By adjusting the pillow to the perfect height, you keep your head elevated at a slight angle. This uses gravity to keep saliva in your throat, keeps your jaw comfortably aligned, and encourages you to breathe through your nose.
Of course, your pillow needs a good partner. If your mattress is old and sagging, your spine will bend, causing your neck to tilt and your mouth to open anyway. Pairing your adjustable pillow with a supportive Newentor mattress keeps your whole body in perfect alignment. When your spine and neck are supported, your face muscles relax naturally without letting your jaw drop. It’s the easiest way to put an end to nighttime slobber!
FAQs about Drooling in Sleep
Is drooling while sleeping a sign of a medical issue?
For most people, drooling is completely harmless and simply a result of gravity or sleeping on your side. However, if you experience sudden, heavy drooling accompanied by loud snoring or gasping for air, it could be a sign of obstructive sleep apnea. If you suspect this, it is best to consult a healthcare professional.
Why do I drool more when I am extremely exhausted?
When you go to bed overtired, your body plunges into a much deeper state of sleep than usual. This causes your facial and swallowing muscles to relax even more heavily, leading to a higher chance of mouth-breathing and drooling.
Can a dental mouthguard stop me from drooling?
Initially, wearing a new nightguard or dental device might actually increase your saliva because your brain mistakes it for food. However, over time, a properly fitted custom mouthguard can help keep your jaw aligned and your mouth shut, helping you stop slobbering while sleeping.
When should I worry about sleep drooling?
If improving your lifestyle and bedding doesn’t stop your drooling, or if your slobbering comes with loud snoring, persistent sore throats, and poor sleep quality, check in with a healthcare provider to rule out underlying health issues.
Bottom Lines
Learning how to prevent drooling in sleep comes down to simple daily habits and the right bed setup. By clearing your sinuses, staying hydrated, and sleeping on your back, you can easily say goodbye to wet wake-up calls.
