Tips

If you frequently wake up with an embarrassing puddle of drool cutely saturating your pillow, you may need to make some changes to your sleeping habits. For some people, only sleeping on your back can stop you from drooling while others experiencing sleep apnea may need more dramatic treatment. Try some of the suggestions below and see a doctor about your condition if you continue to drool during the night.

Preventing Drooling When You Sleep

Try to sleep on your back and prop your head up. Treat sinus infections or allergies so you breathe through your nose instead of your mouth. Consult your doctor to see if you have sleep apnea or a blocked airway, which can cause heavy drooling. Try to reach a healthy weight to lower your risk of sleep apnea.

Side-sleepers are more prone to drooling during the night simply because gravity is causing the mouth to open and allowing drool to pool on your pillow. Try sleeping on your back and tucking yourself in so that you do not shift around during the night.
If you can't sleep without laying on your side, trying propping yourself in a more vertical position to encourage your mouth to close and create a better air flow.

Breathe through your nose, not your mouth. The main reason that people drool is that their nasal sinuses are clogged. As a result, they end up breathing through their mouth and drooling in the process.
- Try applying sinus-clearing products like Vick's Vaporub and Tiger Balm directly under your nose to loosen clogged nostrils.
- Smell essential oils such as Eucalyptus before going to bed to clear sinuses and soothe yourself to sleep.
- Take a hot, steamy shower before bed to allow the pure vapors to cleanse your sinuses.
Warning: Avoid using strong decongestants if you have asthma.
Untreated conditions can cause post nasal drip and excess saliva while you sleep.^{[1]

Drooling is also a symptom of a blocked airway. Visit an ear, nose, and throat doctor to find out if a blocked airway is affecting your ability to breathe through your nose while sleeping.^{[5]

If you are overweight, you have a heightened chance of experiencing sleep apnea. More than half of the 12 million people in the U.S. that experience sleep apnea are overweight. Alter your diet and exercise regularly to reach a healthy weight and decrease your neck girth for easier breathing.^{[6]

Sleep apnea is treated a number of different ways in addition to weight loss recommendations. Those diagnosed with sleep apnea should avoid alcohol, sleeping pills, and sleep deprivation. Simple nasal sprays and saline solution rinses can help clear nasal passages as well.^{[7]

Continuous positive airway pressure (CPAP) is the first treatment that people who are suffering from sleep apnea undergo. CPAP outlines that patients must wear a mask that forces air through the nose and mouth while sleeping. The idea is to have the right amount of air pressure filtering through the air passages to prevent the upper airway tissues from collapsing as you sleep.^{[8]

- Somnoplasty uses radio frequency to constrict the soft palate at the back of the throat and open the airway.
- 'Uvulopalatopharyngoplasty' (surgical procedure), or UPPP/UP3, can remove soft tissue in the back of the throat surgically to open the airway.
- Nasal surgery consists of several procedures that can fix obstructions or deformities like deviated septums.
- A tonsillectomy can remove oversized tonsils that are obstructing your airway.
- Mandibular/maxillary advancement surgery consists of moving the jawbone forward to create space in the throat. This is a rather intense procedure that is reserved for only the worst cases of sleep apnea.^{[11]

Tips

Don't try to sleep with your mouth open to "dry out" the saliva. This will do nothing but give you a sore throat, especially if the room is cool.
