The Garmin Index Sleep Monitor is a lightweight, upper arm sleep tracker designed for those who want advanced sleep tracking and health insights without the need to wear a smartwatch to bed. Ideal for users who prefer comfort or wear analog watches during the day, this armband provides comprehensive overnight data including heart rate, heart rate variability (HRV) status, Pulse Ox sensor readings, and skin temperature. Engineered with a breathable, machine washable band and a compact removable pod, the device is discreet and incredibly comfortable, even for extended use. Its soft nylon-spandex blend ensures a snug yet barely noticeable fit, making it suitable for all-night wear. With up to 7 nights of battery life on a single charge and seamless data syncing and connectivity with the Garmin ecosystem, users benefit from deeper recovery metrics, stress tracking, and Body Battery updates. The device also supports smart wake alarm functionality, choosing the optimal moment to wake you based on sleep cycles—reducing grogginess. Even without a Garmin watch, the Index Sleep Monitor offers standalone functionality, but when paired, it enhances TrueUp activity tracking, training readiness, and women’s health tracking through sleep data integration.
