Garmin has introduced its first dedicated sleep tracker: the Index Sleep Monitor, a lightweight, screenless armband that straps to your upper arm—and aims to revolutionize nighttime tracking without wrist distraction (theverge.com).
Comfortable Design, Built for Sleep
Impressive One‑Week Battery Life
Powered by a small, removable module equipped with motion and optical heart-rate sensors, the device promises up to seven nights of sleep tracking on a single charge. You can easily detach it to recharge while continuing your daily routine uninterrupted (theverge.com).
Deep Dive Into Your Nights
The Index tracks more than just sleep: it measures light, deep, and REM stages, along with heart rate, breathing rate, skin temperature, and stress indicators such as heart rate variability (HRV). It also calculates your daily “Body Battery” to show recovery levels. After sync, the Garmin Connect app delivers a personalized sleep score each morning (theverge.com).
A Smarter Alarm for Gentle Wake-Ups
The smart alarm feature vibrates to wake you during a light sleep stage, helping you rise feeling more refreshed and less drowsy—far gentler than a sudden buzz (theverge.com).
Women’s Health Features & Illness Warnings
By tracking skin temperature overnight, the device can offer insights into menstrual cycles—like ovulation timing and improved period predictions—and even potentially hint at shifts in health before symptoms appear (theverge.com). However, Garmin clarifies this is not a medical device and shouldn’t be used to diagnose or treat any health conditions (theverge.com).
Why It Stands Out
If you prefer not to wear a smartwatch nightly—perhaps reserving it for workouts or daily use—the Index offers a dedicated, distraction‑free way to track sleep. Plus, it costs $169.99, which is significantly lower than subscriptions for other sleep bands, like the Whoop (theverge.com).
Final Thoughts
Garmin’s Index Sleep Monitor brings serious sleep-tracking power in a comfortable, wrist-free package. With advanced sensors, a full week of battery, and smart alarm features, it’s a compelling alternative to wearing a watch to bed.
