Hi everyone,
I wanted to share my experience with the Garmin Sleep Monitor, which unfortunately doesn't work for me.
I’ve always had a naturally low resting heart rate – on some days it even drops to around 37 to 40 bpm. I’ve used several Garmin watches over the years, currently the Tactix 8, and with those devices, heart rate and HRV tracking during sleep has worked well. Sleep and wake-up times were also detected accurately.
With the Sleep Monitor, however, things are very different. When I lie down to rest and my actual heart rate is around 45 bpm, the device often shows values around 90 bpm. Sometimes this lasts for several minutes, sometimes even hours. As a result, the sleep tracking is completely off.
My assumption is that the Sleep Monitor is very energy-efficient and can't handle low heart rate situations properly. That would explain why the data is so inaccurate in my case.
I really like the idea of not having to wear a watch at night, but unless this gets improved with an update, the Sleep Monitor sadly doesn’t work for me.
Would be great to hear if others with low resting heart rate have had similar experiences.
