Lower HRV and higher RHR than on watch

emX0R 4 days ago

I started using Index Sleep Monitor and noticed that my HRV is lower than when I was sleeping with my Enduro 3 watch. RHR is also higher.

I have Sleep Index for about a week only but i don’t feel sick didn’t change my training routine so it would be quite coincidence that the figures would not be affected by the device. Anyway it is also strange as my understanding is both Enduro 3 and Sleep Index uses same sensors.

Anyone noticed similar pattern?

Yes, since using ISM, my HRV is about 10ms lower than before. Also nothing particular has changed. My resting hasn't changed

Same here my HRV dropped when I started using the index… So now I wonder does the watch or sleep index have better accuracy..

exactly, I would expect it should be same as it's same Elevate 5 sensor on both watch and ISM, isn't it? Maybe the difference can be counted towards the way that ISM is not on the wrist.

In any case, it is quite annoying because it looks like lower HRV has also affect on overal stress measurements. It looks like when I wear my watch during the day, the stress is higher than typically - I guess it might be because over night I got much lower HRV than before and that is then affecting whole day.

Yes, my HRV is 5-10ms lower than watch, RHR more or less the same.
