At one stage or another, we’ve all woken up to the sensation of a cold, wet pillow clinging ever so slightly to the side of our face. Why does this happen? Why do we sometimes sleep with our mouths open? And more importantly, can it be prevented?

The Causes of Dribbling

Everyone dribbles, in the day you naturally swallow any saliva produced in your mouth while at night this process is meant to slow down. But for the unlucky, dribbling continues at a rapid pace throughout the night. In fact, there’s even a name for the condition of producing too much saliva: sialorrhea.

There are 2 main causes of pillow dribble:

Breathing through your mouth: Unfortunately you are unconscious when this happens to it’s tricky to know for sure if you tend to open your mouth during the night, but if you are a mouth breather, you are likely going to dribble, and your pillow and morning self will suffer. Generally, you will breathe through your mouth because your nose is failing to provide enough oxygen to your body, so your lungs opt for Plan B and use your mouth for air, which is when saliva takes it chance at a quick escape. A failure of nasal breathe can be any of these issues:

  • Nasal Congestion, particularly during a cold
  • Sinus Infection and Inflammation
  • Allergies
  • Deviated Septum
  • Certain Medications
  • Alcohol
  • Smoking

Your Sleeping Position: This is where gravity works against you and your pillow. If you sleep on your front or side, your mouth is likely to hang open, letting saliva drip freely. Whereas if you sleep on your back, the saliva will pool at the back of your throat and activate your swallowing reflex. As Christopher Y. Chang, an ear, nose and throat surgeon says: ‘The mouth is the path of least resistance. The lips are right there.’

More severe problems that can lead to pillow dribble include neurological conditions that can lead to partial or full facial paralysis.
