Your sleep band analyzes your heart rate variability, sleep quality, and sleep stages to determine your overnight Body Battery™ change. You can expect to see the highest Body Battery change with a good night's sleep. Activity and stress combine to drain your energy throughout the day, while naps and restful moments can slow things down or even give you a boost.

Sync your sleep band with your Garmin Connect™ account to view your most up-to-date Body Battery change, long-term trends, and additional details.
