For many individuals, sleeping on the right side may reduce snoring compared with sleeping on the back. Keeping the airway more open can improve airflow and decrease vibration in the throat. This position may be comfortable for many healthy adults and can contribute to more restful sleep.
On the other hand, many sleep specialists suggest that sleeping on the left side may provide additional advantages, particularly for people who experience acid reflux or gastroesophageal reflux disease (GERD). Because of the natural shape and position of the stomach, lying on the left side may help keep stomach acid from flowing back into the esophagus, reducing nighttime heartburn and irritation that can worsen snoring.
Acid reflux is closely connected to sleep quality. When stomach acid repeatedly reaches the throat, it can irritate surrounding tissues, causing inflammation that narrows the airway. This irritation may make snoring worse and increase nighttime coughing or discomfort. For people with frequent reflux symptoms, changing sleep position is often recommended alongside other lifestyle modifications.
Individuals diagnosed with obstructive sleep apnea should remember that sleep position alone is usually not enough to treat the condition. Although side sleeping may reduce symptoms in some patients, medical evaluation remains essential. Treatments such as continuous positive airway pressure (CPAP), oral appliances, weight management, or surgery may be necessary depending on the severity of the disorder.
