Sense heart rate variability not collecting…

[DanielWW]

For some reason my heart rate variability is rarely being recorded. I wear the Sense while sleeping and it records breathing, heart rate, temp, O2, and sleep/restlessness but almost always says, “no data” for h.r. variability.  I tried wearing it on the other wrist and that didn’t work either. Any suggestions?

i find that my health metrics randomly record data. For last week, I didn’t get a breathing rate any night, but did get the other metrics. In fact, I haven’t had a BR recorded since the most recent update.

then, for last night, I did record a low breathing rate of 8, but no heart rate variability or SP02!

I average just under 7 hours of sleep nightly and have at least one period of sleep over the required 3 hours. My sleep score averages around 80. I wear my Sense on the same wrist and the same snugness. It’s frustrating but apparently that’s just the way it works!

Good luck-

I think I just had a breakthrough on getting health metrics. It seems that after a manual restart of my Sense, it takes three nights before the BR and HRV starts recording. Strangely, although the Sense manual says that it takes 3 nights of data before a temperature is recorded, I still get  a temperature every night even after a restart.

I’ve not read anywhere that it takes 3 nights before the BR and HRV start recording.

Mine has been behaving the same way for the last week.  Yet all other metrics are apparently fine.
