Garmin upgrades sleep tracking on select wearables

A number of Garmin fitness trackers and smartwatches are benefitting from upgraded sleep tracking in Garmin Connect.

Owners of the Vivoactive 3 and Forerunner 645 (as well as their Music variants), Forerunner 935, Vivosport, Vivosmart 3 and Vivomove HR will notice their sleep statistic in the smartphone app have changed. Not just in presentation, but also in accuracy and the level of detail. Other wearables such as those in the Fenix range are not currently included, but will be in the near future.

Previously, Garmin wearables only used movement and heart rate to analyze sleep. The company’s latest update now slaps heart rate variability data to this, i.e. the length of time between a user’s heart beat.

This allows for more more accuracy when capturing the data. The charts and graphs in Garmin Connect now not only show how long you spent in light and deep sleep, but also in REM sleep. Awake time is also shown, along with a separate graph on movement.

Each sleep stage is important, but for different reasons. Light sleep typically accounts for over a half of your kip time. It is important for memory, learning, and letting your body recover from the day. The remainder is split relatively equally between Deep sleep and Rapid Eye Movement (REM). The first promotes a healthy immune system and muscle growth, while the second is important for mental recovery and memory formation. REM is when most dreaming occurs.

During sleep, your body is working to support healthy brain function and maintain your physical health. The way you feel while you’re awake depends in part on what happens while you’re sleeping. Better sleep starts by knowing what’s happening at night.

This is certainly a welcome update, one that makes Garmin wearables even more useful. And its not just current and future data that will be more accurate and more detailed. The company has applied the new algorithms to historical data, too.

  • If you’ve have noticed that your readings show less deep sleep than before this update, it’s not because you’re getting less deep sleep. Our enhanced measurements are just providing more accurate readings.

  • Since the REM sleep update… my Garmin VivoSmart 3 will not record my “fall asleep” time. Usually it starts it recording between half hour – 2 hrs later than i go to bed. I have preset my sleep and awake times. If i try to edit the time afterward… i often lose data. I have reset my bed and wake times… this did not fix the issue. I have also done a factory reset.. which did not solve problem. In addition… when the software made the initial REM updates…. all my previous sleep data was changed… and i lost all data after midnight. Thank you for any input.

    • Hi,

      I just bought a VivoSmart 3 a couple days ago but I didn’t encounter such issue that you mention.
      Did you contact Garmin customer support? Maybe they could give you some recommendations.


    • I have been having exactly the same experience.
      Last night my Vivoactive 3 showed I did not go to sleep until 3 am when in fact I was fast asleep well before midnight .
      Have you discovered any fix yet?
      I’m trawling the net trying to find out what’s happening.
      Surely Garmin won’t leave things in this mess.?

    • Hi, I lose data or minor features occasionally,
      I get everything back by Deleting the app and re-loading it, reboot yr phone at same time usually cures any issues.
      Its a good idea to log into Garmin connect on a laptop/desktop to check yr main data logs before deleting the app.

  • Thanks for sharing update! I am interested in looking at my sleep activity chart every once in a while and Garmin sleep tracker is definitely a good choice!
