Garmin’s latest health tracker is a smart sleep band that attaches to your upper arm. Garmin Index Sleep Monitor offers detailed sleep tracking with sleep stages, sleep score, heart rate variability (HRV) status and breathing variations. There are no screens or buttons; you simply strap the band to your arm before sleep and it starts gathering data.
Garmin Index consists of two parts – an adjustable band made from a breathable nylon/spandex material and a removable puck which houses the sensors.
You get an optical heart rate sensor, blood oxygen saturation (SpO2) monitor, skin temperature sensor and women’s health monitoring.
The data from the Garmin Index syncs to your phone or Garmin watch via the Garmin Connect app. You can also use the device with a smart wake alarm which vibrates only when you’re in a light sleep stage.
Garmin claims seven days of battery life between charges. Garmin Index Sleep Monitor comes in sizes S-XL and retails for $170/€170/£150. It's already available to order on the company’s website, and first shipments are expected in 3-5 weeks’ time.
