Garmin Index Sleep Monitor

The Garmin Index Sleep Monitor is a next-generation wearable sleep tracker designed for comfort and precision. Worn on your upper arm rather than your wrist, it seamlessly measures sleep quality, HRV, breathing variations, skin temperature, and more to give you deeper recovery analysis. The smart vibration alarm helps you wake gently at the right moment, aligned with your sleep stage.

With optical sensors and Pulse OX capabilities, this device provides full overnight biometric data. It also supports women’s health tracking through skin temperature trends and cycle analysis. The Index Sleep Monitor stores up to 7 nights of data and syncs to Garmin Connect for visual insights and trend tracking. Durable yet unobtrusive, it’s a powerful tool for anyone looking to optimize rest, recovery, and performance.
