Design & Build
The Oura Ring 5 uses a high-performance titanium exterior with a seamless titanium interior. Width measures 6.09mm with a thickness of 2.28mm. Weight starts from 2 grams, varying by ring size. The ring is waterproof up to 100 meters (328 ft).
Sensors
Four sensor systems are built into the ring:
- Red and infrared LEDs — measure blood oxygen (SpO2) levels
- Green and infrared LEDs — alternate to track heart rate, HRV, and respiration rate around the clock
- Digital temperature sensor — monitors temperature trends throughout the day and night
- Accelerometer — tracks movement and activity 24/7
Battery & Charging
A single charge delivers 6 to 9 days of battery life, depending on ring size and usage. Charging takes 20 to 80 minutes from the size-specific charger via the included USB-C cable.
Sleep Tracking
Sleep Score
A composite score covering total sleep time, HRV, nighttime movement, sleep regularity, and additional factors — giving a single answer to how well you slept.
Sleep Stages
Breakdown of deep sleep, REM sleep, and light sleep from the previous night, available each morning in the app.
Blood Oxygen Sensing
SpO2 levels are monitored overnight. Deviations can indicate breathing disturbances during sleep.
Bedtime Guidance
The Oura app sends reminders to begin winding down at the optimal time for your sleep targets.
Activity Tracking
Automatic Activity Detection
Over 40 activity types are detected automatically — including cycling, basketball, and housework — with heart rate data logged for each session.
Activity Score
A daily metric covering activity levels, consistency over time, and recovery. Helps identify whether movement and rest are in balance.
Personalized Activity Goals
Daily targets are set based on recovery status. Goals focus on either general activity or calorie burn depending on set health priorities.
Recovery & Readiness
Readiness Score
Combines temperature trends, heart rate, and sleep data to reflect how prepared the body is for the day ahead.
Illness Detection
Shifts in temperature patterns and heart rate are monitored to provide an early signal when the body may be fighting an illness.
Heart Rate Variability (HRV)
Tracked continuously to indicate stress load, recovery status, or when additional rest may be needed.
Resilience
Tracks how well the body bounces back from daily physiological stress and builds a long-term view of stress recovery capacity.
Stress Monitoring
Daytime Stress
Movement, activities, and logged tags are mapped to stress levels throughout the day. The feature shows what elevates stress and what aids recovery.
Cardiovascular Health
24/7 Heart Rate Monitoring
Continuous tracking shows how the heart rate responds to meals, exercise, environment, and rest across the full day and night.
Cardiovascular Age
An estimate of how the cardiovascular system is aging relative to chronological age, based on ongoing biometric data.
Cardio Capacity (VO2 Max)
An estimate of the body’s efficiency in delivering and using oxygen during intense physical effort.
