The Garmin Lily 2 integrates its sleep tracking feature with the Garmin Connect app to provide users with detailed insights and management of their sleep patterns. The watch automatically detects sleep and monitors movement during the user's defined normal sleep hours and uploads this data to the Garmin Connect app, allowing users to review and analyze their sleep statistics.
Sleep Monitoring by Lily 2
Garmin Lily 2 uses its optical heart rate sensor and motion detection to monitor the wearer's sleep. It tracks total hours of sleep, breaks sleep into different stages, monitors sleep movement, and provides a sleep score that reflects overall sleep quality. The watch also has a pulse oximeter feature to detect overnight variations in oxygen saturation (SpO2), which can highlight potential breathing disturbances or sleep apnea events. It records breathing variations with severity based on defined thresholds, helping users gain insight into breathing quality during sleep.
Customization Through Garmin Connect App
Users set their normal sleep hours through the Garmin Connect app, which informs the watch when to track sleep automatically. This allows the sleep tracking to align with the user's typical sleep schedule and improve the accuracy of the data collected. The app provides customizable sleep schedules that can be adjusted for different days of the week, allowing for variations in sleep patterns depending on weekday and weekend routines. These sleep schedules are synced to the watch to ensure the device monitors sleep during intended windows.
Sleep Data Synchronization and Visualization
After monitoring sleep throughout the night or naps during the day, the Lily 2 syncs the collected data to the Garmin Connect app either in real time (if connected) or after the device syncs with the phone. In the app, users can view detailed sleep data including total sleep time, time spent in light, deep, and REM sleep stages, as well as metrics on movements during sleep. The app compiles this information graphically, offering trends over days or weeks to help users understand their sleep patterns over time.
Advanced Sleep Monitoring Features in Garmin Connect
Garmin Connect enhances the sleep data with advanced analytics. It evaluates sleep quality using multiple parameters including sleep duration, stages, and breathing variations. The pulse oximeter-enabled breath variation detection helps identify severity levels of possible sleep apnea, an indication calculated based on criteria from the American Academy of Sleep Medicine. These indicators are presented alongside historical trends in the app to provide users with deeper insights into respiratory events during sleep.
Setting and Managing Sleep Preferences
Within Garmin Connect, users can modify personal profile settings related to sleep, such as age, weight, and typical sleep hours, further refining the accuracy and personalization of sleep tracking. The app enables users to turn on or off pulse oximeter sleep tracking owing to battery and privacy preferences. It also supports activating a do-not-disturb mode, which minimizes notifications during sleep hours, avoiding interruptions except for alarms.
Sleep Data Sharing and Community Features
Garmin Connect is a social and analytical platform where users can share their sleep and activity data with friends or wellness communities. Sharing sleep data allows users to engage in challenges, compare progress, and receive encouragement. This social element promotes better sleep habits and overall health through community support.
Sleep and Activity Cohesion
Data from sleep tracking integrates seamlessly within the broader health and activity monitoring dashboard in Garmin Connect. Sleep statistics are combined with daily activity, heart rate, stress, and recovery metrics to offer holistic health insights. This comprehensive view helps users link their sleep quality with physical and mental wellness, guiding lifestyle changes to improve health outcomes.
Napping and Additional Sleep Insights
The Lily 2 can record naps which are included in the overall sleep statistics in the app, providing a fuller picture of the user's total sleep in a 24-hour period. Naps can be timed or untimed and are visible in the sleep widget on the watch as well as detailed in the Garmin Connect app.
