Garmin released today its new Index Sleep Monitor, a smart sleep band that gives users a closer look at their overnight vitals and recovery. In addition to tracking sleep duration and stages, the Index Sleep Monitor provides users with their overall sleep score, HRV status, Pulse Ox reading (a pulse oximeter that measures how much oxygen is in your bloodstream), breathing variation, respiration rate, skin temperature, women’s health data, stress levels and Body Battery which is Garmin’s branded energy monitoring technology. 

In a press release, Garmin’s vice president of consumer sales and marketing, Susan Lyman, said, “We are thrilled to add the Index Sleep Monitor to our suite of innovative health and wellness products. Wearing this smart sleep band every night can provide in-depth sleep insights and a more complete picture of fitness and recovery so users can wake up ready to seize the day.”

The lightweight, breathable band is worn around the upper arm and comes in two sizes (XS to S; M to XL). After a night of sleep, the data is uploaded into the Garmin Connect app and syncs with other vitals, such as recorded activities, from compatible Garmin smartwatches. This fills in any gaps that one device may miss. 

Cleaning is also easy since the tracking device, a square Apple AirTag-like module, can easily be removed, and the band is machine-washable. It also has a seven-night battery life, which allows for daytime charging. If you don’t wear your smartwatch to bed already, this device frees up the night to be the time to give your watch a charge. 

Smart wake alarm and women’s health tracking

A standout feature of the Index Sleep Monitor is its smart wake alarm. During a pre-selected time frame, the smart band detects when you’re at the lightest stage of sleep and sends subtle vibrations to wake you up. The intention is to leave you feeling refreshed in the morning rather than groggy from deep sleep. This is an innovative feature in competitors’ sleep-tracking devices, such as the Eight Sleep Pod 4. 

While some Garmin smartwatches already have women’s health tracking available in the app, the Index Sleep Monitor utilizes your skin temperature to give further insight into period prediction and ovulation windows. The Garmin Connect app can store users’ data such as symptoms, mood and cycle calendars.  

The Index Sleep Monitor is now available on Garmin’s website for $170.
