Description
Understand your sleep and recovery with the Garmin Index Sleep Monitor S/M in Black. Designed for comfortable overnight wear, this innovative sleep-tracking armband provides detailed insights into your sleep quality, recovery, heart rate variability and overall wellbeing.
Unlike traditional wrist-worn fitness trackers, the Garmin Index Sleep Monitor is worn around your upper arm, making it an excellent choice for anyone who prefers not to wear a smartwatch while sleeping.
Featuring advanced sleep monitoring, skin temperature tracking, Pulse Ox measurements and up to seven nights of battery life, the Index Sleep Monitor helps you understand your overnight recovery through the Garmin Connect app.
Comfortable Upper-Arm Sleep Tracking
The Garmin Index Sleep Monitor features a lightweight, breathable fabric band designed specifically for overnight comfort.
Made from a soft blend of 70% nylon and 30% spandex, the adjustable band fits comfortably around your upper arm without the bulk of a traditional smartwatch.
The S/M size accommodates upper-arm circumferences from 20cm to 29cm, providing a secure fit throughout the night.
Its discreet design makes it ideal for people who want comprehensive sleep tracking without wearing a watch to bed.
Detailed Sleep Score and Sleep Stages
Discover how well you're sleeping with Garmin's advanced sleep monitoring technology.
The Index Sleep Monitor records important overnight information, including sleep duration, sleep stages and sleep quality.
Each morning, you can review your Sleep Score and detailed insights through Garmin Connect, helping you identify patterns and understand how your sleep habits affect recovery.
Tracking your sleep over time can help you make more informed decisions about your bedtime routine and daily activities.
Heart Rate Variability and Recovery Insights
Understand your overnight recovery with heart rate variability (HRV) monitoring.
The Garmin Index Sleep Monitor tracks changes in the time between heartbeats while you sleep, providing valuable information about your body's recovery patterns.
HRV Status helps you identify longer-term trends and understand how factors such as training, stress and rest may affect your wellbeing.
These insights are particularly useful for active individuals who want to balance exercise with appropriate recovery.
Body Battery Energy Monitoring
Garmin's Body Battery technology helps you understand your estimated energy levels.
By analysing information such as sleep, stress and heart rate variability, Body Battery provides insights into how your body recharges overnight.
When used alongside a compatible Garmin smartwatch during the day, the Index Sleep Monitor can contribute to a more complete picture of your energy levels across the full 24-hour period.
Skin Temperature Tracking
Monitor changes in your average skin temperature while you sleep.
The Index Sleep Monitor records overnight temperature trends, allowing you to identify variations that may be associated with your sleep environment, activity levels and general wellbeing.
For users of Garmin's menstrual cycle tracking features, skin temperature information can also support retrospective ovulation estimates and period predictions.
These estimates are intended for general wellness tracking and should not be used for contraception or fertility planning.
Pulse Ox and Breathing Variations
Gain additional insights into your overnight wellbeing with Garmin's Pulse Ox sensor.
The Index Sleep Monitor measures estimated blood oxygen saturation while you sleep and provides information about breathing variations throughout the night.
Combined with respiration rate monitoring, these features offer a more detailed view of your sleeping patterns.
The measurements are intended for general wellness purposes and are not a substitute for medical assessment.
Overnight Heart Rate and Stress Monitoring
The Garmin Index Sleep Monitor continuously samples your heart rate throughout the night.
This information helps provide resting heart rate measurements and contributes to Garmin's sleep and recovery insights.
Overnight stress tracking also helps you understand whether your body experienced relatively calm or elevated stress levels during sleep.
Smart Wake Alarm with Gentle Vibration
Start your morning with Garmin's convenient Smart Wake Alarm.
Instead of relying solely on a traditional audible alarm, the Index Sleep Monitor uses gentle vibrations to wake you during an appropriate point within your selected wake-up window.
This feature is designed to provide a more comfortable waking experience while avoiding the need for a loud alarm.
Seamless Garmin Connect Integration
Review your sleep and recovery information through the Garmin Connect app on a compatible iPhone or Android smartphone.
The Index Sleep Monitor synchronises wirelessly using Bluetooth Low Energy, allowing you to view detailed sleep statistics, trends and wellbeing information.
If you already use a compatible Garmin smartwatch, the sleep monitor can complement your existing Garmin ecosystem by providing overnight data while you leave your watch off.
Up to Seven Nights of Battery Life
Enjoy convenient overnight monitoring with up to seven nights of battery life on a single charge.
The rechargeable lithium-ion battery is designed to support a full week of typical sleep tracking, including Pulse Ox monitoring during approximately eight hours of sleep per night.
The included Garmin charging cable makes recharging straightforward, with a full charge taking approximately 1.5 hours.
Machine-Washable Fabric Band
Keeping your sleep monitor clean is simple.
The soft fabric band is machine washable once the electronic monitoring module has been removed.
This practical design makes the Index Sleep Monitor suitable for regular overnight use while helping maintain comfort and hygiene.

The Garmin Index Sleep Monitor S/M provides a comfortable alternative to traditional wrist-based sleep tracking.
With detailed sleep analysis, HRV Status, Body Battery monitoring, skin temperature tracking and smart wake functionality, it offers valuable information to help you better understand your sleep and recovery.
