Mouth breathing can happen for several reasons. You might naturally sleep with your mouth slightly open, or you may have difficulty breathing through your nose because of congestion, allergies, a cold, or another nasal problem.
Mouth breathing can also contribute to other morning symptoms, including:
Dry mouth
A sore or scratchy throat
Bad breath
Chapped lips
A feeling of thirst after waking
Snoring
Interestingly, drooling and dry mouth can occur together. Although it sounds contradictory, saliva may be produced normally while escaping from an open mouth, leaving the mouth itself feeling dry by morning.
If you regularly wake up with both drooling and a dry throat, your nighttime breathing pattern could be worth paying attention to.
- Your Sleeping Position Could Be the Culprit
The position you sleep in can influence whether saliva stays inside your mouth.
People who sleep on their stomach or side may be more likely to notice drooling because gravity makes it easier for saliva to leave the mouth.
