There’s Actually a Reason Doctors Have Opinions About Which Side You Sleep On

Have you ever wondered whether the side you sleep on actually matters?

You might think that sleeping position is simply a matter of comfort. But your posture during the night can affect things such as reflux symptoms, breathing, pregnancy-related comfort, and even how easily you fall asleep.

There isn’t one “perfect” sleeping position for everyone. However, certain positions may be more comfortable or beneficial depending on your health and individual circumstances.

Here’s what you should know before choosing your usual side of the bed.

1. Sleeping on your left side may help with acid reflux

For people who experience nighttime heartburn or acid reflux, sleeping on the left side may be worth trying.

The stomach is positioned in a way that can make it easier for stomach contents to remain below the connection with the esophagus when you're lying on your left side.

Research has found that left-side sleeping can reduce nighttime acid exposure compared with sleeping on the right side or back.
