The concern: In people with severe liver disease (cirrhosis, enlarged liver), lying on the right side could theoretically compress the liver or affect blood flow. However, there is no strong evidence that right-side sleeping harms a healthy liver.
Who is most at risk: People with advanced liver disease (cirrhosis, hepatomegaly/enlarged liver). The average person has nothing to worry about.
What you can do: If you have liver disease, ask your doctor about optimal sleeping positions. They may recommend left-side sleeping or slight elevation.
4. Heart Palpitations or Discomfort (For Some People)
This is the risk that gets the most attention online, but it’s not what most people think.
What happens: Your heart sits slightly to the left of center in your chest. When you lie on your left side, the heart shifts closer to the chest wall. This can make heartbeats feel more pronounced – a sensation called “palpitations” that is almost always benign.
