The Oura Ring is a smart ring that tracks sleep, activity levels, and health. It is made with precision sensors and state-of-the-art heart rate, heart rate variability (HRV), temperature, activity, and sleep monitoring technology. The Oura Ring is lightweight and non-invasive, making it a convenient way to monitor your health. There is a monthly subscription fee for the Oura Ring, but it is worth it for the insights and data that the ring provides.
Heart rate variability (HRV) is the physiological phenomenon of the variation in the time interval between consecutive heartbeats in milliseconds. A normal, healthy heart will have a higher HRV than an unhealthy heart. A good HRV score is relative for each person. HRV is a highly sensitive metric and responds uniquely for everyone. As a rule of thumb, values below 50 ms are classified as unhealthy, 50–100 ms signal compromised health, and above 100 ms are healthy.
