The Oura Ring monitors over 50 health metrics, primarily focusing on sleep quality, physiological recovery, daytime stress, and activity. It condenses this data into daily, actionable scores—like Readiness and Sleep—to help you balance your lifestyle. [1, 2, 3]

The ring tracks specific categories:

Sleep: Measures sleep stages (Deep, REM, Light), sleep latency (time it takes to fall asleep), efficiency, and nighttime movement. [1]
Heart Health: Tracks 24/7 continuous heart rate, resting heart rate (RHR), and heart rate variability (HRV) to indicate your body’s stress levels and recovery. [1]
Stress & Resilience: Monitors physiological stress throughout the day, tracks recovery periods, and measures your body's long-term resilience to stress. [1]
Temperature Trends: Measures continuous skin temperature to help spot early signs of illness or map out shifts in your menstrual cycle. [1]
Activity & Fitness: Automatically records daily steps, calorie burn, active time, and estimates your Cardio Capacity (VO2 Max) and Cardiovascular Age. [1, 2]
Women's Health: Predicts fertile windows, provides pregnancy insights, monitors perimenopause, and tracks cycle variations. [1, 2]
Blood Oxygen: Tracks nighttime SpO₂ levels and nighttime breathing regularity to detect potential disturbances.
