Improved Digestion
When you sleep on your left side, gravity helps food waste pass more smoothly from the small intestine into the large intestine. The stomach naturally hangs to the left side of the body, and resting on this side can encourage the release of gastric juices and enzymes without unnecessary strain. This position may also ease bloating and discomfort after a heavy dinner.
Relief from Acid Reflux
Acid reflux and heartburn are popular issues, especially for those who eat late at night. Research has shown that lying on the right side can relax the lower esophageal sphincter, the valve that keeps stomach acid from traveling back into the esophagus. On the left side, however, this valve keeps positioned above the level of gastric acid, lowering the chances of nighttime reflux. People with chronic heartburn often find that left-side sleeping offers noticeable relief.
