Apple has unveiled the Apple Watch Series 8 as well as the new Apple Watch SE

The menstrual cycle is an essential indicator of health, and many doctors see it as a significant symptom. Apple Watch Series 8 has unique new temperature-sensing capabilities that provide women with additional insights into their health and are created with the same privacy safeguards as all other health data.

The Apple Watch Series 8 has a two-sensor architecture to reduce bias from the outside world, with one sensor on the back of the watch, closest to the skin, and another immediately beneath the display.

Wrist temperature at night might be an excellent predictor of total body temperature. The sensors on the Apple Watch Series 8 record changes in wrist temperature as little as 0.1° C every five seconds when sleeping. Users may view nightly changes in baseline temperature in the Health app, which can be caused by activity, jet lag, or even disease.

Users may acquire retroactive ovulation estimations using the new temperature-sensing features in Apple Watch Series 8. Knowing when ovulation has happened may be useful for family planning, and the Apple Watch Series 8 makes it simple and accessible by displaying these estimations in the Health app. Temperature monitoring also allows for more accurate period estimates.
