Nighttime Heartburn: It’s Dangerous

Waking with a sore throat, cough, or a bitter taste in your mouth? It could be nighttime acid reflux, and it could be dangerous. In addition to disturbing sleep, nighttime reflux increases the risk of esophageal damage. That's because lying down leaves stomach acid in the esophagus longer. And as we sleep we swallow less acid-neutralizing saliva than when awake.
