How Oura Measures HRV
The Oura Ring measures HRV automatically during sleep using PPG sensors on your finger. It calculates your nightly average and lowest resting HRV, which feeds into your morning Readiness score.
Understanding Readiness
Oura's Readiness score (0-100) incorporates HRV, resting heart rate, body temperature, sleep quality, and activity balance. A score above 70 suggests you're recovered and ready for training; below 70 indicates you may need rest.
