Have you ever wondered why, some mornings, you wake up with the feeling that you slept on the “wrong side”? What if it’s more than just an expression? Some experts claim that our sleeping position could influence much more than just our nighttime comfort. Among them, one is increasingly standing out: sleeping on your left side. But why this side rather than the other? And above all, what benefits does it truly offer? A matter of the heart (literally!)

Sleeping on your right side puts slight pressure on the heart due to the positioning of our internal organs. While studies are still limited, many specialists agree that sleeping on your left side offers better conditions for blood circulation. When sleeping this way, the heart works more freely, without strain—much like an engine running at full speed without resistance. The result: smoother blood flow and a lighter, more rested awakening.
