A doc has given a key warning about hearing your heartbeat when you’re lying down. It could signal a worrying health problem. Sure, in some cases, it might seem okay, but it could also point to hidden health issues that need a doc’s look.
Usually, when you hit the sack, you relax—your breath slows, your muscles unwind, and your heart rate dips. Sometimes, hearing your heartbeat then can mean your body’s working just fine, like after a workout or during a check-up. But docs caution that if you keep hearing it, it might not be so harmless.
