…you should take note of how sleeping position interacts with your digestion, particularly regarding acid reflux and heartburn.

Gastroenterologists and sleep specialists frequently point out that the side you sleep on makes a surprisingly big difference due to human anatomy:

Why Side Matters for Digestion

  1. The Left Side Advantage: Your stomach sits predominantly on the left side of your abdominal cavity. When you sleep on your left side, gravity helps keep the gastric junction (where your esophagus meets your stomach) positioned above the level of gastric acid. This natural barrier prevents stomach acid from easily leaking upward.
  2. The Right Side Tendency: When you sleep on your right side, gravity relaxes the lower esophageal sphincter below the level of stomach acid. For many people—especially those prone to acid reflux, GERD, or “silent” LPR—this can make nighttime heartburn or throat irritation much more likely.

What If You Prefer Sleeping on Your Right Side?

While left-side sleeping is generally championed for digestion and pregnancy (as it relieves pressure off major blood vessels), right-side sleeping does have some cardiovascular benefits for certain individuals because it places less physical weight on the heart.
If you love sleeping on your right side but suffer from nighttime congestion, throat clearing, or reflux, you can easily bridge the gap with a few simple adjustments:
  • Elevate the Head of Your Bed: Raising the head of your bed by 6 inches (using bed risers or a wedge pillow) allows gravity to work in your favor regardless of which side you lie on.
  • Avoid Late Evening Meals: Finishing your last meal 3 hours before lying down gives your stomach time to empty, reducing the volume of acid available to cause trouble overnight.
Are you adjusting your sleep routine to help manage nighttime heartburn, acid reflux, or morning throat clearing?
