Hi , not sure whether I should be asking here regarding my cardiovascular health , but I would definitely appreciate some insight before I do anything about it.

My resting heart rate is kind of low , around 40-50 bpm and generally hovers around 50-60 bpm when doing light tasks.
I monitor my heart rate and saturation levels with an oximeter + AW and so far I don't think my SPO2 levels is anything to be worried about.

But here's the thing , while sleeping , my heart rate is very low (<40 bpm). Every time I sleep I would get low heart rate notifications and the would happen in a span of 10 min at a time. Today alone on my afternoon 'nap' (or sleep ) this has happened twice with a cumulative time of 20 mins having a heart of 36-38 BPM . Having that low of a sleeping heart rate freaks me out lol.

Some info about myself , I'm in my 20s and moderately active with frequent workouts and exercises. But I'm always sleepy and tired most of the time and every time I wake up , regardless having a long nights rest or not , I'd wake up super groggy and have a hard time getting off the bed.

What say you ? Is this something I should be worried about or is it normal.

By resting when awake is usually when sitting down and lying on the bed (completely relaxed) so i guess thats why it hovers around 40-50

I did use a proper oximeter and BP monitor which yielded relatively the same results . I used to frequently do really intense and long cardios , still am but not at the rate I used to and focusing more on moving plates. Its just that its worrying me since I get more and more tired all the time but never has this affected my performance when it came to sports . I think you're right , I should probably go to a checkup . Maybe that my hormone and cortisol levels are off .

After waking up I'd feel dizzy and notice that my cognitive abilities are clouded for a solid hour or two . Just curious whether the low BPMs affected my oxygen levels to a significant extent when sleeping . I'll try to use an oximeter as soon as I wake up.
