Sleep experts are increasingly recommending left-side sleeping as the healthiest nighttime position. While sleeping on your right side might feel natural, research shows it can interfere with several important bodily functions.
Your lymphatic system – the body’s drainage network – works best when you sleep on your left side. This position helps your body efficiently remove waste products overnight. Right-side sleeping may slow this process, potentially leading to fluid retention and reduced detoxification.
Heart health also benefits from left-side sleeping. Since your heart sits slightly left of center, this position reduces strain on your cardiovascular system. Many people with heart conditions report sleeping more comfortably on their left side.
Digestion improves with left-side sleeping too. The position helps prevent acid reflux by using gravity to keep stomach contents in place. People who suffer from nighttime heartburn often find relief simply by switching sleep sides.
While changing sleep positions takes some adjustment, the health benefits make it worth trying. Start by spending just part of the night on your left side, gradually increasing the time as your body adapts.
