If you’re referring to a viral claim about always sleeping on your right side, there isn’t good evidence that sleeping on the right side is inherently dangerous for healthy people.
Your sleeping position can affect certain conditions:
-
Acid reflux/heartburn: Sleeping on the left side often reduces nighttime reflux compared with the right side.
-
Pregnancy: Side sleeping is generally recommended later in pregnancy, with the left side often suggested for comfort, although either side can be appropriate.
-
Snoring or sleep apnea: Side sleeping can be better than sleeping flat on your back for some people.
-
Heart conditions: There isn’t a universal rule that people with heart disease must avoid sleeping on the right side; comfort and the specific condition matter.
For most healthy adults, choose the position that lets you sleep comfortably and breathe normally. There’s no established rule that consistently sleeping on your right side will damage your heart or shorten your life.
If you share the rest of the headline (“you…”), I can fact-check the specific claim.
