Many people find sleeping on the right side comfortable, but the article warns it “may come with surprising drawbacks.”
Research shows this position can worsen acid reflux because it “encourages gastric acid to flow into the esophagus.” Studies found right-side sleeping increased GERD symptoms by about 25%.

The article also links this position to heart strain. It may “put pressure on your heart,” especially in people with cardiac problems, and affect circulation, sometimes causing swelling.

Muscle and nerve pressure are other risks. Right-side sleepers may experience stiffness, tingling, or joint misalignment. Poor circulation at night can also affect detoxification and energy levels, with reports of “fragmenting sleep cycles” and up to 30% worse sleep quality.To reduce these risks, experts suggest raising the head of the bed, avoiding heavy meals before sleep, and trying the left side instead. Pillows can provide support, and rotating positions helps avoid strain.
