About This Section
Garmin’s sleep features assess rest quality and recovery readiness using data collected by the watch during sleep. The primary inputs are heart rate, heart rate variability, movement, and respiration rate, recorded continuously through the night by the Elevate optical sensor and the accelerometer.
Body Battery is the most visible output of the sleep system. It draws on HRV data, stress, and sleep quality to produce a 0–100 energy reserve figure that updates overnight and depletes during the day. Sleep Score summarises the night’s rest as a single number, incorporating duration, sleep stage distribution, and interruptions. Sleep Stages classifies each period of sleep as light, deep, or REM using movement and heart rate patterns.
The remaining features in this section — Sleep Coaching, Sleep Need, Optimal Sleep Window, and Sleep Alignment — are available on current-generation devices running Garmin OS and require Garmin Connect for full presentation. Each page notes the specific devices and firmware versions that support the feature.
