Advanced Sleep Tracking Features
AI-Driven Sleep Analysis
One of the biggest upgrades in the Oura Ring Gen 4 is its AI-powered sleep insights. The device uses a combination of heart rate variability (HRV), blood oxygen levels (SpO2), and temperature trends to offer a detailed breakdown of your sleep cycles.
Accurate Sleep Staging
By analyzing deep sleep, REM sleep, and light sleep patterns, the ring provides highly accurate sleep staging. It gives you a Sleep Score each morning, allowing you to track improvements and make necessary adjustments.
Real-Time Blood Oxygen Monitoring
A major addition in the Oura Ring Gen 4 is its continuous SpO2 tracking, which helps detect sleep disturbances such as sleep apnea or breathing irregularities.
Temperature Sensing for Sleep Optimization
The ring continuously monitors your skin temperature to identify fluctuations that may affect your sleep quality. This feature is particularly useful for tracking signs of illness or hormonal changes.
Comprehensive Health Monitoring
24/7 Heart Rate and HRV Tracking
Beyond sleep, the Oura Ring Gen 4 tracks your resting heart rate and heart rate variability (HRV). These metrics are crucial for assessing stress levels, recovery, and overall cardiovascular health.
Activity and Readiness Score
Unlike traditional fitness trackers, the Oura Ring focuses on recovery and readiness rather than step counting. It provides a Readiness Score each morning, helping you determine whether you should push hard or prioritize rest.
Menstrual and Hormonal Cycle Tracking
With its advanced temperature tracking, the Oura Ring Gen 4 offers accurate menstrual cycle predictions and insights into hormonal fluctuations.
