Most people collapse into bed without thinking twice about how they sleep.
After a long day of work, family, and routines, rest feels like the only goal.
But the position you sleep in might actually impact your health — and experts say sleeping on your left side can offer surprising benefits.
For those who struggle with acid reflux or nighttime heartburn, this position can bring real relief. Sleeping on your left helps keep your stomach below your esophagus, reducing the chances of acid creeping upward. Gravity naturally assists digestion, making this position ideal for comfort.
Your spleen and liver also benefit. The spleen, located on the left side, filters impurities from the blood. Lying on that side improves circulation and helps it function more efficiently. Meanwhile, because the liver sits on the right, left-side sleeping prevents excess pressure and encourages optimal detoxification.
For pregnant women, left-side sleeping is often recommended — especially in the third trimester. This position improves blood flow for both mother and baby, while reducing pressure on the liver and heart. Doctors note that sleeping on the back can sometimes increase pregnancy-related risks.
Digestion gets a boost, too. The ileocecal valve, connecting the small and large intestines, is located on the left. Sleeping in this position helps gravity support waste movement, which may promote regular bowel activity.
Still, left-side sleeping isn’t perfect for everyone. Those with shoulder pain or stiffness might find it uncomfortable. Back sleeping, on the other hand, supports spinal alignment but may worsen snoring or sleep apnea.
Finding the right position is about balance — comfort and health should go hand in hand.
From easing heartburn to supporting circulation, left-side sleeping might be the small nightly change that brings big benefits to your overall well-being.
