• Sleep must be set up with Track Sleep with Apple Watch enabled.
• Sleep Focus must be enabled for at least 4 hours a night for about 5 nights."

Hello joelleen,

At the bottom of the page you came from, Track your nightly wrist temperature changes with Apple Watch - Apple Support, is the following information:

Have a good day.

Hey, I have the same issue. From multiple days of experimenting I can confirm that it is not related to the fit of the Apple Watch as I've tried multiple bands as well as adjusting them to fit as best as possible.

I‘m happy to see I‘m not the only one experiencing issues. I hope this can get resolved.
