Right-side sleeping isn't "bad"—millions of people do it and sleep perfectly well. But for those with specific conditions, it may be less optimal:
-
Acid reflux – The stomach sits higher than the esophagus in this position, making reflux more likely
-
Liver pressure – Your liver, already the largest organ, may experience more compression
-
Lymphatic drainage – The primary drainage pathway is on the left; right-side sleeping may slightly impede this process
That said, some people with certain heart conditions are advised to sleep on their right side. Always follow your healthcare provider's specific recommendations.
How to Make the Switch
If you're a lifelong back or stomach sleeper, switching sides can feel strange at first. Here's how to make it comfortable:
1. Use Pillows Strategically
-
Behind your back – Place a pillow behind you to prevent rolling onto your back during the night
-
Between your knees – This aligns your hips and reduces lower back strain
-
Hug a pillow – Keeps your upper body relaxed and prevents shoulder hunching
2. Choose the Right Mattress
A mattress that's too soft can cause your spine to curve unnaturally, even in a good position. Medium-firm often works best for side sleepers.
3. Give It Time
Your body has muscle memory for sleep positions. It may take 1-2 weeks for left-side sleeping to feel natural. Be patient.
4. Listen to Your Body
If left-side sleeping causes pain (particularly shoulder discomfort), adjust your pillow height or reconsider. Not every position works for every body.
Who Should Be Cautious About Left-Side Sleeping?
While left-side sleeping is beneficial for most people, certain individuals should exercise caution:
-
Those with congestive heart failure – Some patients report increased discomfort on the left side; follow your cardiologist's advice
-
People with shoulder injuries – Side sleeping can aggravate rotator cuff issues; use extra pillow support
-
Anyone with specific surgical history – Recent chest or abdominal surgery may make side sleeping temporarily uncomfortable
When in doubt, ask your doctor. They know your specific health history.
