Many people don’t think about how they sleep, but sleep position can influence overall health. Experts often suggest sleeping on the left side because it may support better digestion and circulation throughout the night.

One key benefit is reduced acid reflux. When you lie on your left side, the stomach stays below the esophagus, making it harder for acid to move upward. This positioning, combined with gravity, can help ease heartburn and nighttime discomfort.

Sleeping on the left side may also aid digestion and circulation. It can help food pass more smoothly through the intestines and may reduce bloating. This position also supports the spleen, located on the left, by potentially improving blood flow and its role in filtering the blood.

However, this position isn’t ideal for everyone. Some people experience shoulder discomfort or stiffness. While back sleeping can support spinal alignment, it may worsen snoring or sleep apnea. In the end, the best sleep position is one that feels comfortable while supporting your overall health.
