The claim “If you usually sleep on your right side, there’s something important you should know…” is typically presented as clickbait. The reality is more nuanced.
Research suggests that sleep position can affect certain medical conditions, but there is no evidence that sleeping on your right side is inherently dangerous for most people.
Here’s what studies have found:
- Acid reflux (GERD): Sleeping on the left side often reduces nighttime acid reflux, while sleeping on the right side may make reflux worse for some people.
- Pregnancy: Pregnant women, especially later in pregnancy, are often advised to sleep on their side. While the left side has traditionally been preferred, current evidence suggests that either side is generally acceptable unless a healthcare professional recommends otherwise.
- Heart failure: Some people with heart failure find that lying on their left side is uncomfortable and may prefer the right side, but this varies by individual.
For healthy adults, there is no strong evidence that regularly sleeping on your right side causes harm or indicates a health problem.
Bottom line
If you sleep well on your right side and don’t have conditions like acid reflux, there’s usually no reason to change your sleeping position. If you experience frequent heartburn, snoring, sleep apnea symptoms, or persistent pain related to your sleep position, discuss these symptoms with a healthcare professional, who can recommend the most appropriate sleeping position for your situation.
