This is a possibility where your overall health is in a normal state, but your sleeping position is encouraging you to drool on your pillow.

Your Mouth is Open While Sleeping
You may have experienced drool because your mouth stays open, letting the saliva go out of your mouth directly.
When your mouth is open during your deep sleep, your jaw muscles are relaxed, and the esophagus is closed.
That means you might be in good health, but your mouth stays open during deep sleep.
Breathing through Your Mouth
Drooling on your pillow at times is caused by the blocked nasal passages due to sinusitis, colds, or allergic reactions.
Since breathing becomes challenging, your mouth is forced to open to inhale and release some air.
While you’re sleeping, your clogged nose does not function well, resulting in the airways looking for an alternative exit.
Saliva Overproduction
There are moments when you are drooling due to the excess saliva in your mouth.
As your mouth produces saliva, drooling on your pillow might become consistent every night.
Other triggers for saliva overproduction are certain medications, consuming spicy meals, and acid reflux.
This can be resolved if you lessen the impact of saliva overproduction triggers, like consuming less spicy foods.
Sleeping Too Deep
When you are sleeping deeply, you often don’t realize that you have been drooling.
This occurs because your body doesn’t respond immediately during deep sleep.
