Discover Garmin’s new Index Sleep Monitor, a comfortable upper-arm sleep tracker with advanced features like heart rate, respiration, and skin temperature monitoring, lasting up to 7 days on a single charge.
Garmin has taken a fresh approach to sleep tracking with its latest release—the Index Sleep Monitor, a smart armband designed to provide accurate overnight data without the need to wear a smartwatch to bed. For many, wearing a smartwatch while sleeping isn’t ideal—it's bulky, can be distracting with notifications, and might need to charge overnight. The Index Sleep Monitor solves this with a comfortable design that straps around your upper arm, allowing your smartwatch to rest while you do.
This wearable isn’t just about comfort. The Garmin Index Sleep Monitor delivers detailed insights into your nightly rest, tracking light, deep, and REM sleep stages. It goes further by monitoring your heart rate and breathing, giving you a complete view of how your body is recovering overnight. Each morning, you’ll receive a personalized sleep score that helps you better understand your sleep quality and what factors may be affecting it.
One standout feature is the built-in thermometer that keeps track of your skin temperature. These readings can show how your environment affects your sleep and may even signal early signs of illness. For women, the temperature data also supports enhanced menstrual cycle tracking, offering predictions and past ovulation estimates. Still, Garmin clearly states the device is not a medical device and shouldn't be used for diagnosis, treatment, or as a contraceptive method.
Powering the device is a removable electronic module that includes motion and optical heart rate sensors. It’s built for convenience, lasting up to seven days on a single charge, meaning you can track a full week’s sleep before needing to recharge.
The Index Sleep Monitor also supports respiration rate tracking and, in regions where it's supported, blood oxygen saturation monitoring. These features help users notice changes in breathing that could indicate issues worth addressing.
Another key health insight available through the Garmin Connect mobile app is heart rate variability (HRV), which can signal how well your body is handling stress or fatigue. Combined with the app’s Body Battery metric, you’ll get a snapshot of how much energy you’ve got left in the tank, helping you adjust your rest accordingly.
Unlike smartwatches that send constant alerts and updates, the Index Sleep Monitor is distraction-free. It does include vibration support, but only for its smart alarm feature, which is designed to gently wake you during lighter sleep stages, helping you feel more refreshed in the morning.
If you prefer charging your smartwatch overnight, but still want to track your sleep accurately, Garmin’s Index Sleep Monitor is an ideal solution. It blends comfort, advanced sleep tracking, and long battery life into a sleek package.
The Garmin Index Sleep Monitor is now available on Garmin’s official store in two size options (S-M and L-XL) and is priced at $169.99. It’s a smart pick for anyone serious about improving their sleep without sacrificing the comfort of their night routine.
