Thanks to the partnership between Natural Cycles and Samsung's sensor technology, the watch can monitor temperature changes and estimate basal body temperature (BBT), a key marker for menstrual tracking, while you sleep. 

The new feature will be rolled out progressively through Samsung Health app updates in the U.S., Korea, and 30 European markets, according to Samsung. 

To activate the new feature, users will need to go to their Samsung Health app, add their most recent cycle information, and then turn on "Predict period with skin temp" in settings.

Keeping track of menstrual cycles is an important practice for women because it helps them better understand their health and bodies and can help with reproductive health, such as family planning and pregnancy prevention.
