Sleeping on your left side can offer several surprising health benefits, especially for digestion, circulation, and sleep quality. One of the most notable advantages is its impact on acid reflux. In this position, the stomach sits lower than the esophagus, making it harder for stomach acid to rise and cause heartburn. For people with GERD, this simple adjustment can significantly reduce discomfort and improve nighttime rest.
Left-side sleeping also supports important organs like the spleen and liver. Because the spleen is located on the left, this position enhances blood flow and allows it to filter impurities more efficiently, strengthening the immune system. The liver may also function better due to improved circulation and reduced congestion, helping the body detoxify more effectively.
