Garmin Instinct can track your sleep. Once you are asleep the watch starts to track your sleep by monitoring your heart and movements during normal sleep hours.
You can manually set your normal sleep hours using the Garmin Connect app or web.
The sleep stats you get on the watch include levels of sleep, stages of sleep, and movements made while asleep.

How Do You Active Sleep Mode on Garmin Instinct?
Garmin Instinct will be able to monitor the total time spent sleeping, duration of movements, and restful sleep while resting.
You can either set Garmin Instinct to sleep mode or set your normal sleep time to facilitate the reading of sleep data.
Instinct has to be worn in bed so that movements can be tracked during rest periods.
Follow the steps below to enable sleep mode on Garmin Instinct, as well as Fenix 3 series, Tactix Bravo, D2 Bravo, and Quatix 3:
- Open the Main Menu
- Choose Settings
- Then Activity Tracking
- And then, Go to Sleep
If you want to use the Garmin Connect App to set your normal sleep time from your mobile follow the steps below:
Launch the Garmin Connect app on your Android or iOS device
- Select Settings
- Select User Settings
- Edit Bed Time or Wake Time
- Touch the back button to head back once you are done
To set your sleep time using the Garmin Connect website follow the given steps:
- Sign in/log in to your Garmin Connect account.
- Click the menu icon (on your upper left side).
- Choose Devices.
- Under your device select User Settings.
- Enter normal Sleep Start Time and Sleep End Time (for example, 9.00 P.M, 6 AM).
- Click the Save button at the bottom of the page.
- All is set, click Connect to head back to your dashboard.
When you sync with Garmin Instinct the normal sleep time gets updated. On the other hand, the sleep data on Garmin Connect reflects the period interval.
Garmin Instinct will monitor your rest activities when the normal preset sleep time in Connect is used.
You will need to confirm the sleep time in order to see the sleep graph after the upload to Garmin Connect is complete.
No confirmation is necessary when the device is placed on Sleep Mode because the recorded sleep data will automatically upload with the sleep time.
Garmin Instinct Sleep Tracking Statistics
Garmin establishes your baseline heart rate when worn during the day. The watch should be worn at least 2 hours before going to bed so that baseline is established.
The baseline is essential because it lets Garmin automatically start monitoring your sleep. This happens when the heart rate slows below the baseline heart rate.
As earlier mentioned Instinct will monitor total sleep hours, sleep movements, and sleep levels, and use the data to create logs and charts accessible via Garmin Connect.
From the connect dashboard you will notice the total time you were in various stages or levels of sleep (light, deep, and REM sleep).
No need to talk about how to log into the Garmin Connect account to access the metrics, the process is easy once the app is on your phone.
