Apple watch is not tracking sleep stages and REM sleep

I have Apple Watch 7 running Watch OS 9 and even though I have everything active and my sleep schedule set up, my watch is not recording or showing the different sleep stages. Please help me out.

I tried everything mentioned in every online forum and none of the proposed solutions worked. The solution turned out to be to just clean the bottom of the watch where all the sensors are. Apparently the underside of the watch was so dirty that the sensors weren’t reading whatever they needed to read.

Even though you do what we’ve found to work, it’s still has a lot of improvement to be done.


Today my toddler woke up in the middle of the night and for some reason I turned off the sleep focus. So now I have half the night with proper sleep stages analysis and half without.


If I take a nap (say on Saturday) it show hours later, without sleep stages (even if I manually turn on sleep focus) and show in the Sunday’s chart.
