Do You Wake Up With a Wet Pillow?
Why Drooling Happens
Drooling during sleep is common and “usually isn’t cause for concern.” It often occurs during deep REM sleep when “the muscles around the mouth and jaw loosen,” allowing saliva to escape instead of being swallowed.
Sleeping Position
Position matters: “People who sleep on their stomach or side are more likely to drool” because gravity pulls saliva out, while back sleepers swallow more easily.
Other Causes
“Nasal congestion caused by allergies, colds, or sinus infections” forces mouth breathing, increasing drooling. Health issues like “acid reflux, sleep apnea, or neurological disorders” can also play a role, as can poor oral hygiene.
When to See a Doctor
Occasional drooling is natural, but if it’s frequent or comes with symptoms like “choking or disrupted sleep,” seek medical advice. Simple fixes—adjusting sleep position or treating congestion—often help.
