Heart rate variability

15 replies

Bubbles254 · 21/09/2023 16:22

If you have a fitness tracker wwhat is your heart rate variability and how much does it vary? What do you do that increases it?

I have noticed on my fitbit that when my overnight hrv is low I feel terrible the next day even if my sleep is good so I have been trying to work out the reason for the variation.

It does seem to be linked to how much sun I had the previous day so I am wondering if vit d would help boost it.

Low hrv for me is around 16. It seems to go up to 30 something after a sunny day in the UK and 40 on holiday somewhere hot.

How old are you? Mine has similar variation, which is about right for my age. Mine goes down if I drink too much or don't sleep well.

Mid 40s. It does not sleep to correlate with sleep though, my fitbit often records sleep scores in the 80s with low hrv and scores the the 60s with high hrv

My HRV averages 20, I’m not sure if that is good or bad.

Where is it on the Fitbit? My resting heart rate is 69. I know if I'm getting ill because it will go up to 73 or more

themez · 21/09/2023 19:35

Oh. Just found it. 22

Mine's normally in the 80s somewhere, often drops a bit if I'm a bit under the weather though there have been times when my HRV is normal but I'm definitely poorly, and vice versa.

That is high. Do you have a fitbit or another health tracker? They all seem to measure differently.

Mine is usually around 35 but can drop to 15 if I drink a few glasses of wine

The main thing that knocks mine out of whack is a tough run. I did an ultramarathon last weekend and it has been lower than normal since.

PosiePerkinPootleFlump · 21/09/2023 20:24

My normal is about 52-55. It drops to high 40s when I'm shattered after a race

dammit88 · 21/09/2023 20:27

mine is 51 as my overnight average and 75ms as highest 5 min average. I don't really understand what it means!

UnaOfStormhold · 21/09/2023 20:33

Mine is a garmin. And yes, it's pretty high. That said I'm pretty active and have a low resting heart rate (40s).

mrsmoppp · 21/09/2023 21:55

My testing rate has been 71 today and the highest it's been is 149

southchinasea · 21/09/2023 22:02

Mine also seems to go up if I take extra vitamin D or spend time in the sun.

80sMum · 21/09/2023 22:03

Just looked at mine for the past 3 weeks. The lowest was 18 and the highest was 41. Both of those are outside my normal range, which seems to average about 30.
