Hi Michael,

I got a generation 3 Oura Ring just before the holidays and have loved using it ever since. Having said that, I have found a few trends that I find somewhat concerning. One of which is my HRV; my 90-day average is 28ms, which seems to be quite low compared to the graph in the video and over the past month it has been closer to 20! I have included it, along with a few other graphs from my Oura ring. I know this is a broad question, but what do you make of this?

HRV - 28ms (90-day average) 

Daily Steps 16,547 (90-day average) 

Lowest RHR - 52bmp (90-day average) 

Sleep 7.1hr/night (90-day average)

Hi drewab, your HRV is definitely low. 16,000 steps/d is a lot-from my experience, my worst HRV data occurs when I'm overtrained. I can't say if that's what's causing your HRV #s, as many factors contribute.

Keep in mind that different devices and manufacturers measure differently and accuracy varies wildly. EliteHRV.com has an app that can be used with a chest strap and it'd be a good way to get an idea of where you are.

And as Michael points out, overtraining will often drop HRV significantly (as will sitting on the couch 🙂
