⚠️Keep Waking Up With a Wet Pillow? Here’s What Could Be Behind Nighttime Drooling… 👇

Your sleeping position can also make a noticeable difference. People who sleep on their stomachs or sides may be more likely to drool because gravity can encourage saliva to move toward the edge of the mouth.

Sleeping on your back, by contrast, may reduce drooling for some people. In this position, gravity generally helps keep saliva inside the mouth, making it less likely to leak onto your pillow.

Mouth breathing is another common factor. A blocked or stuffy nose caused by allergies, a cold, or congestion can force you to breathe through your mouth, increasing the likelihood that your mouth will remain open during sleep.
