Inside the ring: Oura’s sensor technology
Oura’s accuracy and depth of insight stem from its advanced sensor suite:
- Infrared PPG Sensors: These sensors measure heart rate, heart rate variability (HRV), and respiratory rate by detecting changes in blood volume in the finger arteries. Infrared light is less susceptible to interference from skin pigmentation compared to the green light used in many wrist wearables.
- NTC Body Temperature Sensor: Measures skin temperature deviation throughout the night with high sensitivity (detecting changes as small as 0.1 degrees Celsius). This is crucial for tracking circadian rhythm, illness detection, and potentially predicting menstrual cycles.
- 3D Accelerometer: Tracks movement to determine activity levels during the day and restlessness or wakefulness during sleep.
These sensors work together, collecting thousands of data points continuously, providing the raw material for Oura’s sophisticated analysis.
Decoding Oura’s scores: Sleep, Readiness, Activity
Oura synthesizes complex data into three primary scores (0-100):
- Sleep Score: Evaluates overall sleep quality based on:
- Total Sleep: Duration of sleep.
- Efficiency: Percentage of time in bed actually spent asleep.
- Restfulness: Amount of tossing and turning or wake-ups.
- REM Sleep: Time spent in the mentally restorative REM stage.
- Deep Sleep: Time spent in the physically restorative deep sleep stage.
- Latency: How quickly you fell asleep.
- Timing: Alignment of sleep schedule with your body’s natural circadian rhythm.
- Readiness Score: Assesses your capacity to perform mentally and physically, indicating recovery status. Key contributors include:
- Previous Night’s Sleep Score.
- Sleep Balance: Comparison of recent sleep to long-term needs.
- Previous Day Activity: Impact of yesterday’s physical exertion.
- Activity Balance: Balance between recent activity and rest over time.
- Body Temperature: Deviation from your baseline.
- Resting Heart Rate (RHR): How low your heart rate dropped during the night.
- Heart Rate Variability (HRV) Balance: Comparison of recent HRV to your baseline.
- Recovery Index: How quickly your heart rate stabilized during the first half of the night.
- Activity Score: Measures how well you are balancing activity, inactivity, and rest throughout the day. Contributors include:
- Stay Active: Frequency of avoiding long periods of inactivity.
- Move Every Hour: Consistency in getting up and moving.
- Meet Daily Targets: Progress towards personalized activity goals.
- Training Frequency & Volume: Balance of workouts over time.
- Recovery Time: Ensuring sufficient rest days between intense activities.
These scores provide a quick daily check-in, while drilling down into the contributors reveals detailed insights.
AI-driven insights and personalization
Oura’s AI plays a crucial role in transforming raw sensor data into meaningful scores and guidance:

- Baseline Calculation: Learns your individual norms for metrics like HRV, RHR, and temperature over time, allowing it to detect significant deviations.
- Personalized Recommendations: Based on your scores and data trends, the app provides tailored advice, such as suggesting an earlier bedtime after a night of low deep sleep, recommending a rest day if Readiness is low, or encouraging more movement if activity goals aren’t met.
- Trend Analysis: Identifies long-term patterns and correlations, helping users understand how lifestyle factors impact their biometrics.
- Predictive Features (Potential): Features like Period Prediction leverage temperature data analysis.
Optimizing rest with Oura data
Oura provides specific data points crucial for sleep optimization:
- Detailed Sleep Stages: Understanding the balance between Light, Deep, and REM helps identify specific areas for improvement (e.g., consistently low deep sleep might prompt investigation into sleep environment or pre-bed routines).
- Nighttime HRV: Tracking HRV trends during sleep provides a powerful indicator of recovery and nervous system balance. Lower-than-usual HRV can signal stress, illness, or overtraining.
- Resting Heart Rate: A consistently low RHR during sleep is a good sign of cardiovascular fitness and recovery. Spikes can indicate stress or illness.
- Body Temperature Deviation: Subtle changes can signal the onset of illness even before symptoms appear, or reflect hormonal changes. Consistent temperature patterns support circadian rhythm analysis.
- Respiratory Rate: Significant deviations from baseline breathing rate during sleep can sometimes indicate health issues.
By monitoring these metrics, users can experiment with lifestyle changes (diet, exercise timing, stress management techniques, sleep environment adjustments) and observe their impact on sleep quality and recovery.
Readiness: Balancing stress and recovery
The Readiness score is arguably Oura’s most unique contribution, acting as a daily guide for balancing exertion and recovery:
- High Readiness: Suggests your body is well-recovered and capable of handling challenges, both physical and mental.
