How Garmin’s Index Sleep Monitor Redefines Nightly Recovery

How did you sleep? Garmin’s new Index™ Sleep Monitor has the answer. This ultra-comfortable and lightweight smart sleep band tracks your sleep for a more comprehensive view of overall fitness and recovery. Designed as a breathable upper-arm band, it delivers in-depth insights into nightly recovery while feeling natural enough to wear every night.

With up to 7 nights of battery life and continuous Pulse Ox tracking, the Index Sleep Monitor extends Garmin’s wellness ecosystem, where movement, rest, and resilience are measured together.

More Than Hours of Rest

Each morning, the Index Sleep Monitor provides a personalised sleep score (0–100) in the Garmin Connect™ app, calculated from sleep duration, stress, stages, and more. It shows when you moved between light, deep, and REM sleep while also tracking HRV status, blood oxygen saturation, respiration rates, breathing variations, and skin temperature changes.

Over time, the device builds a personalised baseline, helping you spot patterns in your recovery and overall wellness.

Rest and Recover with Advanced Tracking

Throughout the night, the Index Sleep Monitor tracks the following metrics, all viewable in Garmin Connect:

• Sleep score: A personalised score (0–100) based on sleep duration, stress, and stages.
• Sleep stages: Light, deep, and REM sleep tracking.
• HRV status: Average HRV and recovery insights (balanced, unbalanced, low, or poor).
• Pulse Ox: Blood oxygen saturation during sleep¹.
• Breathing variations: Shifts in breathing patterns when combined with Pulse Ox¹.
• Respiration: Respiration rates throughout the night.
• Skin temperature: Variations linked to activity, environment, or potential illness.
• Women’s health tracking: Improved cycle predictions and retrospective ovulation estimates², plus integrated menstrual cycle or pregnancy tracking.
• Body Battery™ energy monitoring: See if your body is charged or needs more rest.
• Stress tracking: Understand whether your sleep was calm, balanced, or stressful.

When it’s time to wake up, the smart wake alarm looks at lighter sleep stages during a pre-selected window and gently wakes you with a light vibration, so you feel more refreshed.

A Seamless Part of the Garmin World

You don’t need another Garmin device to benefit from the Index Sleep Monitor. Wear it at night, sync with the free Garmin Connect™ app, and wake up to a full breakdown of your rest.

For those who also use a Garmin smartwatch, the Index Sleep Monitor fills in gaps, if you prefer not to wear your watch at night, combining metrics for an even more complete picture of your health. Daytime activity and training meet nighttime recovery and resilience, giving you the clarity to make smarter choices.

Designed for Daily Life

A sleep device needs to feel effortless. The Index Sleep Monitor comes in two sizes (S–M and L–XL), made with breathable fabric that feels soft against the skin. When it needs a refresh, simply remove the module and wash the strap in the machine on a gentle cycle. With up to a week of battery life, you won’t need to think about charging every day.

“We are thrilled to add the Index Sleep Monitor to our suite of innovative health and wellness products. Wearing this smart sleep band every night can provide in-depth sleep insights and a more complete picture of fitness and recovery so users can wake up ready to seize the day.”
