Why Your Sleeping Position Could Be Worsening Acid Reflux

Many people focus on diet, medication, and lifestyle changes when trying to manage acid reflux, but one factor is often overlooked: sleeping position. According to digestive health experts, the way a person sleeps may influence how easily stomach acid travels back into the esophagus during the night.

Acid reflux occurs when stomach contents move upward into the esophagus, causing symptoms such as heartburn, chest discomfort, a sour taste in the mouth, coughing, or throat irritation. For some individuals, symptoms become worse while lying down because gravity no longer helps keep stomach contents in place.

Researchers have spent years studying how body position affects reflux. Interestingly, several studies have suggested that sleeping on the left side may reduce reflux episodes compared with sleeping on the right side. This difference appears to be related to the natural anatomy of the stomach and esophagus.
