I have a low heart rate some times. Just when sitting on the couch in the evening, lying down (before sleeping) I can have a heartrate as low as 51. Mostly my resting heart rate is between 51 and 60.

So I don't even know what it's like when I'm sleeping. I probably don't want to know.

Anyway, I feel fine albeit a bit 'slow' and when I get up to walk or do something, my heartrate also immediately climbs up. So there is probably nothing 'wrong' per se.

But since I'm not a sporter / athlete at all, I'm just wondering how this might work. Could my anxiety be the cause for a lower heartrate? And why would it do that?

Anyone else has this?
