Baseline wrist temperature not establishing

Hello everyone


i am having an issue with my new Apple Watch 8 ultra. I have been wearing the watch every night and it seems that the baseline temperature is not being established. My wife’s new watch has already established after 5 nights (and showed the progress to that each night in the icon) but mine has shown no progress. Is there any way to reset it to fix it? Any other ideas?


Thanks for the help!

Hello rzande1,


Let's double check to make sure you meet the criteria below for that feature:


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.


You can also find those details in this resource: Track your nightly wrist temperature changes with Apple Watch - Apple Support


If you meet those criteria you'll want to reach out to Apple Support: Contact - Official Apple Support They'd be in the best position to assist further with that behavior.


Take care.
