Rest easy with the Index Sleep Monitor smart sleep band from Garmin
Lightweight band tracks sleep stages, HRV status, breathing variations, skin temperature and more—all while maximizing comfort
Singapore, 19 June 2025 – Garmin Singapore today announced the Index Sleep Monitor, an ultra-comfortable and lightweight smart sleep band that tracks sleep for a more comprehensive view of overall fitness and recovery.
Featuring up to 7 nights of battery life with continuous Pulse Ox tracking, the Index Sleep Monitor is worn on the upper arm and tracks sleep stages, heart rate variability (HRV) status, breathing variations, skin temperature and more to calculate a sleep score for users and provide valuable insights about their health1. After a night of sleep, the data seamlessly syncs to the Garmin Connect smartphone app and can be combined with metrics from a compatible Garmin smartwatch to fill in gaps in data for users who don’t wear their watch at night or are looking to better understand how well they recovered.
“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.” — Mr. Scoppen Lin, Assistant General Manager, Garmin Asia.
Rest and recover
Throughout the night, the Index Sleep Monitor tracks the following sleep and recovery metrics, which can then be viewed in Garmin Connect:
- Sleep score: Every morning, receive a personalized score (0-100) for last night’s sleep based on sleep duration, stress, sleep stages and more.
- Sleep stages: View light, deep and REM sleep stages and when they occur during the night.
- HRV status: See last night’s average HRV and status (balanced, unbalanced, low or poor). After several nights of wear, the smart sleep band will establish a personal baseline to help provide a better understanding of recovery and overall wellness.
- Pulse Ox: Track blood oxygen saturation during sleep1.
- Breathing variations: Used in conjunction with Pulse Ox, view and better understand shifts in breathing patterns while sleeping1.
- Respiration: View respiration rates throughout the night.
- Skin temperature: Track skin temperature changes, which can be related to recent activity, sleep environment, potential illness and more.
- Women’s health tracking: Using skin temperature, women can get more insights into their menstrual cycle, including improved period predictions and past ovulation estimates2. Women can also track their menstrual cycle or pregnancy and get exercise and nutrition education in the Garmin Connect app.
- Body Battery energy monitoring: View energy levels to see if the body is charged or needs more rest. Users who wear a compatible smartwatch while awake can get a more complete picture of their energy levels—day and night.
- Stress tracking: See if last night’s sleep was calm, balanced or stressful.
When it’s time to wake up, the smart wake alarm feature looks at lighter sleep stages during a pre-selected window of time to gently wake users with a light vibration so they feel more refreshed.
Available in two sizes (S-M and L-XL), the Index Sleep Monitor is easy to clean; just remove the module and toss the band into the washing machine on the gentle cycle. It is available at a suggested retail price of SGD 459, retailing at Garmin Brand Stores, Lazada, Shopee, Garmin Online Store, Takashimaya and all authorized retailers.
