Most people don’t think much about how they sleep, but experts say sleeping on your left side may offer some health benefits.
One major benefit is digestion. Sleeping on the left side can help food and waste move more naturally through the digestive system, which may reduce bloating and discomfort. It can also help with acid reflux and heartburn by making it harder for stomach acid to flow back into the esophagus.
Some experts also believe left-side sleeping may support circulation and heart health, especially during pregnancy, since it can reduce pressure on important blood vessels and improve blood flow to the baby.
Side sleeping may also improve breathing by helping keep airways open, which can reduce snoring and mild sleep apnea symptoms.
Still, there’s no single “best” sleep position for everyone. Comfort matters most, and many people naturally change positions throughout the night.
