Monitoring Resting Heart Rate & HRV
In the Oura app, you can see how your nighttime resting heart rate and HRV vary throughout the night.
The graphs are based on 5-minute averages. You’ll find both graphs in the readiness detail view.
Update June 3:
The new Oura ring’s highly accurate infrared LED sensors have made it possible for us to fine-tune the HRV algorithm to better capture exceptionally high values (over 150). As a result of improved data quality overall, you may also see a maximum 5 point increase in HRV numbers around 10-40. In addition, users who have previously spotted gaps in their HRV graphs should now see more solid curves.
Fine-tuned algorithm is available on iOS (app version 2.6.0 with ring firmware 1.19.1) and Android (app version 2.5.0 with ring firmware 1.19.1).
What can I learn from the graphs?
Tracking how your resting heart rate changes throughout the night helps you understand how your body and mind recover from daily strain. Learn more about heart rate while sleeping.
Heart rate variability is a good indicator of especially cardiovascular, but also overall health and general fitness. Your HRV can react to changes in your body even earlier than resting heart rate, so keeping an eye on your own HRV baseline and trends can provide useful insights into your recovery and wellbeing.
