Deep Sleep - Why is it such an issue with Garmin

hjdykes 14 days ago

Anyone else having terrible results with the Sleep function on their watch?

I use a Forerunner 965. I consistantly get 7.5 - 8 hours of sleep. I get 1.5-1.45 hours of REM but ZERO Deep Sleep resulting in a sleep score in the 60's.

It wasn't too bad a problem earlier but lately, I seem to be getting 5 mins max and most nights ZERO Deep Sleep. It's annoying when I have AI training apps trying to determine how well rested I am for training analytics. Now Garmin wants us to buy their AI training analytics. How can we honestly think this is a good feature if the sleep and HRV data is garbage? Garbage in gives Garbage out.

i found results can vary a great deal between different garmin watch models including the 945... different sensors. different technology...

the only way to accurately measure sleep is in a lab covering your scalp with sensors. the watch is just guessing... it cant measure sleep that accurately from your wrist... my watch says i've had a solid nights sleep and doesnt register that i may have been awake for hours... as long as I'm lying still, it registers it as sleep.... and thats even with a newer model than the 945. plus garmin arent putting out frequent software updates any more for the 945, they focus on the newer models... .
