Acid reflux doesn’t only depend on what you eat—it can also be influenced by how you sleep. Health experts say that sleeping position may play an important role in nighttime acid reflux, with some positions making symptoms worse than others.
Research suggests that sleeping on the left side may help reduce acid reflux by keeping the junction between the stomach and esophagus above the level of stomach contents, making it more difficult for acid to flow back upward. By contrast, sleeping on the right side may allow stomach acid to reach the esophagus more easily in some people, potentially leading to increased heartburn, coughing, or a bitter taste during the night.
Doctors note that sleep position is just one factor. Eating large or late-night meals, consuming trigger foods, being overweight, drinking alcohol, and smoking can all increase the likelihood of nighttime reflux. Other strategies that may help include elevating the head of the bed, using a reflux wedge pillow, and waiting at least two to three hours after eating before lying down.
For people with frequent or persistent acid reflux symptoms, healthcare professionals recommend seeking medical advice, as ongoing reflux may require treatment to prevent complications. Combining healthy lifestyle habits with appropriate medical care can help many individuals reduce symptoms and improve their quality of sleep.
