“Normal” resting Heart rate is considered 60-100 , anything below 60 is considered “bradycardia” & supposedly should be evaluated by a medical professional if you’re not considered an athlete, yet when we’re sleeping , it’s considered normal for anyone’s heart rate to drop between 40-60. Why isn’t the normal resting heart rate documented to be between 40-100 while awake rather than 60-100? What’s the difference between sleeping doing absolutely nothing & laying down awake doing absolutely nothing. 40 while awake somehow requires a trip to the doctor if you’re not an athlete but if you’re asleep, it’s perfectly fine? I’m trying to understand how this makes sense.

Think of it like a computer – when you’re doing nothing but sitting down, there a bunch of applications running in the background: you’re seeing, listening, noticing surroundings and there *sliver* of your brain ready to react if a seagull crashes through your window.
When you’re asleep – it’s like you’re well, in sleep mode. The processes have mostly all stopped except for a few key ones that are necessary to wake you up and get back to normal. So it would make sense that the less “background” tasks in your body require less blood, so your heart beats less.
