Why Sleeping on Your Left Side Could Support Better Digestion and Heart Health

When it comes to sleep, most of us focus on quantity over position. After a packed day of work, family responsibilities, and everything in between, the goal is usually just to get into bed and get some rest—no matter how we happen to lie down.

But while we’re asleep, our bodies are hard at work—digesting, repairing, and rebalancing. That’s why the position you sleep in could actually influence more than just how rested you feel in the morning.

We all have our habits: some people prefer sleeping on their back, others on their right side, and some curl up on their left. What many don’t realize, though, is that sleeping on your left side may come with specific health benefits.

Here are a few reasons why it might be the best position for your body:

Why Left-Side Sleeping Might Be Good for You

Relief from Nighttime Heartburn
If you often wake up with a burning sensation in your chest, your sleep position could be part of the problem. Sleeping on your left side may help reduce heartburn by keeping your stomach lower than your esophagus, making it harder for stomach acid to rise back up.

Helping the Liver and Spleen Do Their Jobs
The position you sleep in can impact how well your organs function. Lying on your left side may encourage better blood flow to the spleen, which filters waste and supports immunity. It may also ease pressure on the liver, allowing it to process toxins and waste more effectively while you rest.

Recommended for Pregnancy
Left-side sleeping is often advised during pregnancy, especially in the later stages. Experts like those from the Sleep Foundation recommend it because it promotes healthy blood flow and reduces pressure on the liver. This position also helps the heart circulate blood more efficiently, supporting both mother and baby.

Supports Healthy Digestion
Digestion doesn’t stop while you sleep—and the left side might give your system a little boost. This position aligns with the natural flow of your digestive tract, particularly around the ileocecal valve, helping waste move more smoothly from the small to large intestine.

It’s Okay to Change It Up
While left-side sleeping has some clear benefits, it’s not for everyone. If you feel discomfort in your shoulder or hip, don’t hesitate to adjust. The most important thing is to sleep in a way that feels right for your body. Switching positions from time to time can help prevent soreness and improve overall comfort.

Everyone sleeps differently—but a small change in how you rest could make a big difference in how you feel. What’s your favorite sleep position? Share your thoughts below!
