Garmin beefs up its wearables with advanced sleep monitoring

This month, GPS navigation and wearable technology specialists Garmin have quietly rolled out a software upgrade which significantly improve the sleep monitoring accuracy and functionality of its smartwatches and activity trackers.

Garmin Connect, the app that powers its wearables now features advanced sleep monitoring, which offers capabilities similar to that of its rival FitBit, who rolled out a similar upgrade to their sleep tracking algorithms last year.

The two stand out features of the update are the ability to now track sleep stages, and the addition of heart-rate variability as a metric in its sleep-sensing algorithms.

Garmin sleep stages

Previously, Garmin Connect only allowed you to see your sleep cycles with a breakdown consisting of; light sleep, deep sleep and awake time.

Now, the upgrade means you can also track the amount of time you spent in REM (rapid eye movement) sleep.

REM sleep, the time when we experience most of our dreaming is a vital stage of sleep associated with memories, emotional processing and lots more.

Heart rate variability

The other big update is the ability for Garmin’s wearables to measure heart-rate variability (HRV). Whilst many of its smartwatches could previously measure heart rate from its from the optical HR sensor, Garmin says that incorporating HRV into its sleep algorithms enables more accuracy and “to better measure your time awake and time spent in each sleep stage.”The update is available immediately for the following Garmin watches:

  • Forerunner 645
  • Forerunner 935
  • vívosport
  • vívosmart 3
  • vívomove HR
  • vívoactive3
  • vivoactive 3 Music
  • Forerunner 645 Music

and will be available on other wearables and smartwatches like the Fenix 5 line of devices soon.
