If you’re like most people, you probably don’t think much about how you sleep. Picture this: after a long day at work, taking care of the kids, cooking dinner, and maybe relaxing with a book or TV, you’re finally ready for bed. You’re so tired that you just crawl into bed, turn off the lights, and drift off without giving your sleeping position a second thought.

Most of us just want enough sleep to get through the next day, right? But, it turns out, there’s more happening in your body during those recommended eight hours than you might think. That’s why it could be worth considering the side you sleep on.

Everyone has a favorite sleeping position—some sleep on their right side, some on their left, and others on their back. But did you know that sleeping on your left side could actually benefit your health? Here are a few reasons why:

Nighttime Heartburn
If you deal with acid reflux or heartburn, sleeping on your left side might help. This position keeps your stomach below your esophagus, making it less likely for stomach acid to flow back up and cause discomfort.

Spleen and Liver Function
Sleeping on your left side may help your spleen and liver work better. The spleen, which helps filter out impurities and supports your immune system, can function more effectively in this position because it’s easier for blood to flow there. The liver, which sits on your right side, also benefits because left-side sleeping supports better detoxification and helps the liver process waste.

For Pregnant Women
Experts, like those at the Sleep Foundation, suggest that pregnant women should sleep on their left side when possible. This position makes it easier for the heart to pump blood through the body, which is especially helpful in the later months of pregnancy. Left-side sleeping reduces pressure on the liver and keeps the blood flowing smoothly, making it safer and more comfortable.

Better Bowel Movements
Did you know that sleeping on your left side may even help with digestion? This position benefits the ileocecal valve (which connects your small and large intestines) and can aid in waste movement. Gravity helps this process along, making it easier for the body to eliminate waste.

When to Change Sleeping Positions
Of course, left-side sleeping isn’t the only option. Different positions have different benefits, and the most important thing is to be comfortable. If left-side sleeping causes shoulder pain or discomfort, don’t hesitate to try another position. Switching up positions can actually prevent stiffness and help with any body aches.
