Left-side sleeping may also support digestion by allowing gravity to help food and waste move more naturally through parts of the digestive system. Some people find this position more comfortable after eating or when dealing with bloating.
The article also discusses possible benefits for circulation and the brain’s waste-clearing system during sleep. However, research on some of these effects is still developing, so sleeping on the left side should not be treated as a cure for medical problems.
