Hi
I have noticed my Garmin forerunner 55 and Connect app record resting heart rate during sleep. This seems to contradict the Apple health app with regards to resting heart rate.
Over a few months I stopped sleeping with my watch because it was a bit irritating. But for the last two weeks I started to wear it while sleeping. As a result my resting heart dropped, this got flagged by the apple health app.
If this is not correct please sort out the Garmin data processing
thanks
