The Garmin Index Sleep Monitor is a dedicated upper-arm sleep band built to measure the night more accurately than a wrist device can. Worn comfortably on the bicep, it captures sleep stages, heart rate variability, blood oxygen, respiration and skin temperature while you rest, then delivers a clear Sleep Score and morning recovery picture in the Garmin Connect app. A gentle smart-wake alarm eases you awake during lighter sleep, and integrated women’s health tracking rounds out a complete recovery tool. Use it on its own or pair it with your Garmin watch.
