SLEEP TRACKING
How did you sleep? The Index Sleep Monitor gives you insight with sleep score, sleep stages, HRV status and more1, so you can better understand how well you recovered.
COMFORTABLE DESIGN
Worn on the upper arm, this lightweight and breathable smart sleep band comes in two sizes, allowing you to get the data you need without compromising comfort.
SEAMLESS DATA SYNCING
The Index Sleep Monitor seamlessly syncs your data with the Garmin Connect™ smartphone app. If you wear a compatible Garmin smartwatch during the day or a heart rate monitor during workouts, your data will seamlessly sync via Garmin Connect for more insight into your health and fitness.
BREATHING VARIATIONS
For a closer glimpse of your health, the breathing variations feature uses Pulse Ox to help you better understand shifts in your breathing patterns as you sleep.
SLEEP DATA INTEGRATION
Don’t wear your compatible smartwatch to bed? The Index Sleep Monitor can help fill in the gaps. It provides the sleep data needed for a more complete picture of your training metrics, including training readiness, recovery time and more.
WOMEN’S HEALTH
Using skin temperature, get more insight into your menstrual cycle, including better period predictions and past ovulation estimates3. Track your menstrual cycle or pregnancy plus get exercise and nutrition education in the Garmin Connect app.
