Naps are not added to your sleep statistics
When it comes to sleep tracking on the Garmin Forerunner 15, it's important to note that naps are not included in the sleep statistics. This means that the device is designed to track your typical sleep window and will not account for any nap or rest time outside of this primary sleep period. This feature has been a source of disappointment for some users who value the ability to track naps as a way to boost their recovery and overall athletic performance.
While the Garmin Forerunner 15 offers insights into your sleep patterns, it focuses solely on your main sleep session each day. When setting up the device, you are prompted to establish a sleep window, indicating the hours during which the in-depth sleep tracking will occur. This is similar to the approach taken by Apple's Sleep Schedule for the Apple Watch and iPhone.
The exclusion of naps from the sleep statistics may be attributed to the device's design and functionality. Garmin's sleep tracking feature operates by monitoring your rest during the specified sleep window. If the device detects significant movement or an elevated heart rate for an extended period, it may interpret this as an indication that you have entered an ""awake" state. Consequently, the watch might discontinue sleep recording for the remainder of the night.
It's worth noting that other smartwatches and sleep trackers in the market offer more comprehensive nap tracking features. For instance, the Oura Ring, Whoop 4.0, Fitbit, and Samsung devices are capable of automatically detecting naps and adjusting your overall readiness and sleep scores accordingly. These competitors allow manual nap logging as well, providing a more flexible approach to sleep tracking.
While the Garmin Forerunner 15 may not be the ideal choice for those seeking nap tracking capabilities, it remains a popular option among athletes for its other features. However, if you prioritize the inclusion of naps in your sleep statistics, you may consider exploring alternative devices that cater to this specific need.
