Awake Time
Is anyone aware of how Apple Watch 8 determines that I am awake while in sleep focus? Heart rate, hand movement, leg movement?????

Hi Intensity7491,
Thanks for coming to Apple Support Communities for help today.
It's going to be a combination of things including respiration and movement as well as waking up and checking your watch or iPhone. Please see: Track your sleep on Apple Watch and use Sleep on iPhone.
One way to get more accurate results:
"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."
Have a fantastic day!
