We all have our favorite sleeping position—but did you know that the way you sleep can affect your health in surprising ways? While sleeping on your right side may feel comfortable, studies suggest that it can have hidden effects on your heart, digestion, and overall body function. Here’s what your body might be trying to tell you when you prefer that position.
1. It May Strain Your Heart 
Sleeping on your right side can slightly compress the area around your heart. For healthy people, this may not cause major issues, but for those with heart conditions, it could reduce blood flow and make it harder for the heart to pump efficiently. That’s why doctors often recommend left-side sleeping for people with heart problems—it allows better circulation and less pressure on the chest.
2. It Can Slow Digestion 
When you sleep on your right side, gravity causes your stomach and digestive acids to shift, which can lead to acid reflux or heartburn, especially after a heavy meal. Sleeping on your left side, however, helps food move more smoothly from the stomach to the intestines and supports better digestion.
3. It Might Affect Lymphatic Drainage 
Your lymphatic system removes waste and toxins from the body. Studies suggest that the left side is more efficient for lymphatic drainage because the body’s main lymph duct (the thoracic duct) is located there. Sleeping on the right side may slow down this detox process over time.
