Apple Watch / Body Temperature
I have the setting on to take my temperature, but it doesn’t. I have worn the watch for two days and in the health app it says no data versus needs more data. How can I get my new Apple Watch 8 to use this feature?

DaddyGriz,
Thanks for connecting with us here in Apple Support Communities. This is a great new feature of the Apple Watch. There are certain requirements that need to be met to access your base temperature. One of those would be that you have to wait 5 nights to get a baseline. Check out this article: Track your nightly wrist temperature changes with Apple Watch - Apple Support
"About Wrist Temperature
Your wrist temperature is a measurement related to your body's temperature taken by your Apple Watch while you're asleep. Your body temperature naturally fluctuates and can vary each night due to your diet and exercise, alcohol consumption, sleep environment, or physiological factors such as menstrual cycles and illness. After about 5 nights, your Apple Watch will determine your baseline wrist temperature and look for nightly changes to it.
If you use Cycle Tracking, your wrist temperature can also be used to provide retrospective ovulation estimates and improve period predictions.
Here's what you need
- An Apple Watch Series 8 or Apple Watch Ultra.
- 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."
Have a great day.
