However, not all side-sleeping positions have identical effects.
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.
