When the participants slept on their right side, almost no change in ECG activity was found. The researchers found that in this position, the heart was held in place by the thin layer of tissue between the lungs called the mediastinum.
Even though lying on your left side may change your heart’s electrical activity, there’s no evidence that it increases your risk of developing a heart condition if you don’t already have one.
Anecdotally, people with congestive heart failure often report discomfort and trouble breathing when sleeping on their left side. More research needs to be done to understand if sleeping on your left side is dangerous for people with heart conditions or how dangerous it may be.

However, at this time there’s no evidence that sleeping on your right side increases your risk of developing heart failure, and it seems to be safe.
Some doctors recommend that pregnant people sleep on their left side. Because your liver is on the right side of your abdomen, lying on your left side helps keep the uterus off that large organ and it also makes your heart’s job easier because it keeps the fetus’ weight from applying pressure to the large vein (called the inferior vena cava) that carries blood back to the heart from your feet and legs to improve blood flow to the fetus.

Sleeping on your stomach may alleviate sleep apnea and snoring, but can also cause neck or back pain. Untreated sleep apnea is associated with an
If you have an implantable cardioverter defibrillator (ICD), you may find it more comfortable to sleep on the opposite side that it’s implanted. Most of ICDs are located on the left side.
