-
How it works: Left-side sleep keeps your esophageal sphincter above stomach acid—like a drain cap staying dry.
-
The proof: 89% of chronic reflux patients report 50% fewer nighttime symptoms when switching sides (American Journal of Gastroenterology).
-
Why right-side fails: It submerges the valve, tripling reflux risk in pH studies.
2. Constipation Relief: Gravity’s Natural Laxative
-
How it works: Your colon’s final segment travels down the left side. Sleeping left lets gravity assist waste movement.
-
The proof: Left-side sleepers report 27% more regular morning bowel movements (Neurogastroenterology & Motility).
-
Real impact: IBS-C patients cut laxative use by 40% in two weeks.
3. Bloating Reduction: Stomach Juice Optimization
-
How it works: Aligning your stomach’s curve to the left lets digestive juices flow with gravity.
-
The proof: Ultrasounds show 30% faster gastric emptying after heavy meals (Journal of Clinical Gastroenterology).
-
Why it matters: Less trapped gas = fewer “food baby” mornings.
