The proof: Left-side sleepers report 27% more regular morning bowel movements than back/right-side sleepers (Neurogastroenterology & Motility).
Real impact: For IBS-C patients, this cuts laxative use by 40% in 2 weeks.
3. Bloating Reduction: Stomach Juice Optimization
How it works: Left-side positioning aligns your stomach’s natural curve, letting gastric juices flow with gravity—not against it.
The proof: Ultrasound scans show 30% faster gastric emptying in left-side sleepers after heavy meals (Journal of Clinical Gastroenterology).
Why it matters: Less trapped gas = fewer “food baby” mornings.
4. Pancreas Support: Enzyme Release Boost
How it works: Your pancreas (slightly left of center) releases enzymes into the small intestine—a process gravity accelerates when lying left.
The proof: Left-side sleepers show 22% higher nutrient absorption in blood tests (Gut journal).
Hidden bonus: Better blood sugar stability overnight (critical for prediabetes).
Myth vs. Reality: What the Data Actually Says
“Left-side sleep cures IBS”
False: Itmanagessymptoms but doesn’t cure root causes
World Gastroenterology Organisation
“Only works if you’re sick”
True: Healthy people gain subtle benefits (faster digestion, better sleep)
NIH Sleep-Digestion Study
“Right-side sleep is dangerous”
False: Harmless for most—butavoid if you have reflux/constipation
