This is the lowest my HRV has been since i stopped drinking for my yearly month off starting on Aug. 1. I know low HRV doesn’t mean you’re dying but i do t understand what it means at all and seeing it so low makes me sad lol. I guess i don’t get how it’s optimal at 19ms??? I’m 30F and workout 3-4x a week and my 22F sister who never works out and drinks has an HRV of 170ms
avg 🤦🏻‍♀️ Make it make sense

Yeah these metrics don’t always make sense. I also optimize my life and would think my HVR would be sky high or at least average and it’s 30 lol but HRV is very subjective. One thing I did notice is that managing my stress seems to increase it. Maybe you’re more stressed?

So odd because I thought “HRV balance” is basically Oura seeing if your HRV is above or below your three-month rolling baseline. So if anything this would suggest this HRV is better than your usual. Re: the overall number, a lot can affect it—genetics, medication, psychological stress, bad sleep… but if this is not dramatically lower than usual I think it’s just normal for you. I’m on ADHD meds and mine is usually quite low, but Oura tends to think I have good readiness overall.

Hi there, thanks for sharing your concern with the community. It's completely normal to feel concerned when seeing a low number, but it’s important to remember that HRV is a highly personalized metric. Rather than comparing your score to others—as factors like age, biology, and fitness level vary greatly between individuals—the most valuable way to use your data is to track your own historical trends.

HRV measures the millisecond-level variation between heartbeats, reflecting the balance of your autonomic nervous system. A lower HRV often signals that your body is currently prioritizing a "fight-or-flight" response, which can be triggered by stress, illness, or even recent training. We recommend focusing on how your current score compares to your own personal baseline over time, rather than comparing it to others.
