Aids digestion. Our small intestine transfers waste to our large intestine through the ileocecal valve, located in our lower right abdomen. (A dysfunction of this valvewill play a role in intestinal disorders.)
Reduces heartburn. The theorythat left-side sleeping aids digestion and waste elimination was born from Ayurvedic principles, but modern research also supports this idea. A 2010 studyTrusted Source of 10 participants found a relationship between laying on the right side and increased cases of heartburn (also known as GERD) than when laying on the left side. Researchers theorize that if we lie on the left side, the stomach and its gastric juices remain lower than the esophagus while we sleep.
Boosts brain health. Our minds benefit from side sleeping because we have gunk there, too. When compared to back or stomach sleeping, sleeping on your left or right side helps your body clear what’s called interstitial wastefrom the brain. This brain cleanse may help reduce your risk of developing Alzheimer’s, Parkinson’s, and other neurological diseases.
Reduces snoring or sleep apnea.Sleeping on your side keeps your tongue from falling into your throat and partially blocking your airway. If side sleeping doesn’t alleviate your snoring or you suspect you have untreated sleep apnea, talk to your doctor to find a solution that works for you.
