Garmin Index Sleep Monitor – Smart Upper Arm Band for Sleep Stage, HRV & Recovery Tracking
The Garmin Index Sleep Monitor is a dedicated upper-arm sleep tracking band designed for people who want comprehensive sleep data without wearing a smartwatch to bed. Worn comfortably on the upper arm, it tracks sleep stages, HRV status, blood oxygen, breathing variations, skin temperature, Body Battery, and stress through the night — all synced to Garmin Connect the next morning. Available in two sizes (S-M and L-XL) and fully machine washable for effortless care.
- Tracks sleep score, sleep stages, HRV, breathing variations, and blood oxygen overnight
- Comfortable breathable upper-arm band — available in S-M (8.5”–13”) and L-XL (12.5”–17.5”)
- Skin temperature tracking to detect health changes and support menstrual cycle predictions
- Up to 7 nights battery life — band is fully machine washable (remove module first)
- Syncs with Garmin Connect and pairs with compatible Garmin smartwatches for a complete health picture
Complete Overnight Recovery Picture:
The Index Sleep Monitor pairs seamlessly with existing Garmin wearables to fill the sleep data gap. If you already wear a Garmin watch during the day, the sleep band completes your 24-hour health profile with richer overnight metrics including Body Battery energy trends, stress detection, and respiration tracking — giving you a more accurate readiness score for training and daily performance.
