WHAT'S INCLUDED IN THE BOX?

Garmin Index Sleep Monitor

Charging/Data Cable

Track Deeper Sleep Without Disrupting It

Say goodbye to wrist straps and sleep gadgets that get in the way. The Garmin Index Sleep Monitor was designed to prioritize comfort, worn on the upper arm with a soft, breathable, machine-washable band. It feels light, stays out of the way, and gives you a full night’s rest while quietly tracking what matters: sleep score, sleep stages, HRV, and more. Two sizes ensure a fit that won’t bug you mid-snooze.

  • Upper-arm design avoids wrist discomfort
  • Lightweight, breathable fabric for all-night wear
  • Available in two sizes for a personalized fit
  • Machine-washable band for easy upkeep

Real Sleep Metrics That Power Smarter Recovery

The Index Sleep Monitor captures the details you can’t feel, like your heart rate, breathing changes, oxygen saturation, and sleep cycle patterns. With these insights, you’ll get a clearer picture of how restful your nights actually are—and how ready you are to take on the day. HRV status, stress levels, respiration rates, and even your body’s energy levels (Body Battery™) are all part of the data story.

  • Tracks sleep score, HRV, respiration, and more
  • Pulse Ox sensor monitors blood oxygen levels during sleep
  • HRV status gives insight into readiness and recovery
  • Body Battery™ energy tracking helps gauge your overall recharge

Designed to Sync Your Sleep With Your Life

Already use a Garmin smartwatch or heart rate monitor during the day? The Index Sleep Monitor seamlessly fills in the nighttime gap. Your data flows into Garmin Connect automatically, building a continuous wellness picture—day and night. From training readiness to recovery time, the integration ensures you’re not missing crucial info simply because you left your watch off overnight.

  • Auto-syncs with Garmin Connect via smartphone
  • Completes your Garmin wellness profile
  • Compatible with other Garmin wearables for a 24/7 view
  • Improves insight into training, stress, and health metrics

Track Skin Temperature, Wake Smarter, and Support Women’s Health

Go beyond basic sleep tracking. The Index Sleep Monitor includes advanced features like average skin temperature tracking to detect changes related to illness, activity, or environmental shifts. Women can also track menstrual cycles, get past ovulation estimates, and receive period predictions with skin temperature data. Plus, the Smart Wake alarm uses vibration to gently wake you when your body is ready, not just when the clock says so.

  • Skin temperature tracking for health and environmental awareness
  • Women’s health insights including ovulation and cycle tracking
  • Smart Wake vibration alarm wakes you during the optimal phase
  • Stress and respiration tracking show your sleep state quality
