High heart rate spikes on FitBit during the night?

[Irishflower]

I've been obsessing over my nightly heart rate graph every morning and it's giving me major anxiety.
I've noticed high heart rate spikes now and again during my sleep on my FitBit watch, upto 90/100 beats per minute.
I'm hoping it could be me just turning over in bed, or shuffling around changing position or even a dream/REM sleep.
But I'm freaking out about sleep apnea as I've heard your heart rate can spike up when you stop breathing.
Has anyone experienced their FitBit have high spikes during their sleep?

I'm not sure they're massively accurate in the night to be honest. Probably get knocked around etc as you say. Also I think bad dreams etc can increase your heart rate.

But I'm not medical! Just don't really trust my Fitbit. Give your GP a call.

Thanks I will do. I just don't know how
Reliable these watches are and I feel for someone who's already got massive health anxiety this is not helping.

I stopped wearing mine altogether because of health anxiety

This is why I won't wear one. Although DH Lent his to a neighbor for a day. He has the app so showed him the results. There were some worrying abnormal reading so he said tactfully to his wife that he should visit his GP. They didn't, we were worried a week later he had a stroke. So perhaps there is a use for them.

@Irishflower do you snore??

I had this issue and got rid of my Fitbit 5 years ago.

Well massively freaking out after reading this 😳
I do a bit yes.

Fitbits are notorious for the HR not being accurate-if fact any older wrist HR monitor is known for its inaccuracy. I can be sat down and my HR monitor spikes on my Garmin however I have an ILR so I pop record and it goes whizzing off to my pacing team and they call me if something has happened (only time has been when my ILR was removed from my body for 12 whilst having heart surgery). If you are truly concerned then contact your GP and they can start the process for applying for a Holter to be done

I have health anxiety. I do not wear a Fitbit because it would set off my health anxiety. I really don't need to know what my heart is doing - my assumption is that if I'm well and not noticing anything strange, I'm ok.

I honestly don't know how people cope with wearing them, but I guess most people don't have health anxiety 😂

My friend went to were GP about the opposite,hers was dipping too low. GP told her to ditch her fitbit and rolled his eyes 🤣

**her not were

Everyone has apneas during the night so will have the spikes you talk about. It's perfectly normal. It only becomes the condition 'sleep apnea' if you have more than 10 per hour.

Totally normal OP. You're waking up for microseconds or having dreams. No big deal at all!

I wont wear one of these watches as they stress me out too much.

I've just looked at mine. It's similar. I'm not worried about it.

Thank you for this 😊

Yeah I should have said that I see them all the time too, it's normal.

I really value the RHR, I don't know if it's truly accurate but whatever it's recording, it tells me my trends, and it's helped me spot anaemia twice now.

Sorry his abnormality wasn't heart spikes. And he's in his 70s. He's much better now though.

I was referred for a low heart rate (with symptoms) and was given a proper heart rate monitor over 5 days. It came back as exactly what the Fitbit recorded. Extremely accurate.

Heart rate can go up at night for various reasons. Dreams, adrenalin rushes.

Your cortisol levels peak at 2am for some reason. Something to do with waking the body from sleep. I would imagine that that might affect heart rate.

I go into cardio/peak every night around midnight according to mine, except I’m pretty sure that I don’t. It’s also not listed under the heart rate zones where it says ‘where you got your minutes’. I get a list of every bit of exercise I did, but never anything at midnight. I’m sure it’s a blip.

Hi! The exact same thing happens to me! I figured it must be some sort of blip. It only shows up on the “heart rate zones” and not on the “resting heart rate” side. I also noticed some days, if I check the heart rate zones first thing in the morning, everything is normal. As soon as I do an activity that gets my heart rate into fat burn, the abnormal 12am or 1am spike appears. So glad to hear I’m not alone in this. Scared the crap out of me for awhile.

OH has learnt not to worry after doing some research. I'd never wear one, too neurotic
