Acid reflux
This condition, in which acid backs up from your stomach into your esophagus, can affect your sleep whether or not it results in heartburn. “With heartburn, the discomfort wakes you up. But even if you don’t feel a burning sensation, the acid in your esophagus triggers a muscular reflex to clear it, which can disrupt sleep,” says David Johnson, M.D., a professor of medicine and chief of gastroenterology at Eastern Virginia Medical School. This helps explain why people with chronic acid reflux are more than twice as likely to have sleep problems.
