Apple watch is not tracking sleep stages and REM sleep


I have Apple Watch Series 3 running Watch OS 8.8.1 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.

How do you do that. Restore to old updates.

Mine measures time asleep and HR/RR, but does not measure sleep stages. This started a few days ago and has continued since updating. This is one of the biggest reasons I have the watch - it is fully charged, sleep is set, it’s at the same tightness as it has always been with the same watch band, none of the discussion above applies. Please help

Hey there shilpenp,


If you're running into trouble with tracking sleep on your Apple Watch, we recommend working through the steps below to help resolve it:


If you paired your Apple Watch after completing Sleep setup, you can still turn on Track Sleep with Apple Watch. In the Watch app on your iPhone, tap the My Watch tab, then tap Sleep. Then tap Track Sleep with Apple Watch to turn on this setting. To get the most accurate results when wearing your watch to sleep:
* Turn on Charging Reminders. On your iPhone, open the Watch app and tap the My Watch tab, then tap Sleep. Tap Charging Reminders to turn on a reminder on your Apple Watch to charge before your Wind Down time. If your watch battery dies, it won't track your sleep data.
* Make sure that you're wearing your Apple Watch at a comfortable fit. If your watch is too loose, the accelerometer might register too much movement during your natural sleep.
