Garmin has introduced its latest innovation in sleep tracking—a comfortable, upper arm sleep monitor designed to help you understand your sleep quality better. The new Index Sleep Monitor offers a more comfortable alternative to traditional wrist-worn devices, making it easier to wear overnight without discomfort. This sleek device tracks various sleep stages, heart rate, and breathing patterns to provide a comprehensive picture of your overall fitness and recovery. Each morning, you’ll receive a personalized sleep score, giving you clear insights into how well you slept.
Available now through Garmin’s online store, the Index Sleep Monitor comes in small/medium and large/x-large sizes for $169.99. The device features a small, removable electronic module equipped with motion sensors and an optical heart rate sensor that can last up to seven days on a single charge, eliminating the hassle of daily charging.
Beyond basic sleep tracking, the Index can monitor light, deep, and REM sleep stages, as well as respiration rates. When paired with blood oxygen saturation measurements—which are available in select countries—it can help you understand breathing shifts during sleep. A built-in skin temperature sensor offers insights into how your environment or health may be affecting your sleep, and it can even help track women’s health by providing more accurate menstrual cycle predictions and ovulation estimates.
While Garmin emphasizes that the Index Sleep Monitor is not a medical device and shouldn’t be used for diagnosing or monitoring health conditions, it still offers valuable health insights. The Garmin Connect app provides additional metrics such as stress levels based on sleep patterns, a Body Battery score indicating your energy reserves, and heart rate variability (HRV), which can signal stress or fatigue levels—helping you identify if you need to prioritize rest.
For those who prefer not to wear a device all night or need their smartwatch’s battery for daytime use, the Index Sleep Monitor is an excellent alternative. It tracks sleep metrics without interruptions and features vibration alerts used solely for a smart alarm system that gently wakes you during light sleep stages.
Stay on top of your health and sleep with Garmin’s innovative sleep tracking solution—designed for comfort, accuracy, and ease of use.
