I wake up in the morning and check “sleep”. It gives me reading. Several hours later the reading changes for no apparent reason.

I go to sleep at 10 pm and wake up at 6am.  I check “sleep” and it gives me a reading. Several hours later, for no apparent reason, the reading changes dramatically. Why?

  • I believe I remember reading that sleep data is calculated on Garmin servers and will continue to update after it analyzes further.  Mine changes some after the first sync everyday as well.  Generally by just a few minutes, but I will say it seems more accurate later in the day when I sync again and recheck the data.  

  • Thank you very much for your reply. I  am new to Garmin and had thought I may have a wrong setting, but your answer makes sense to me ( though sometimes the change is my reading sleep reading is quite significant ).
