Samsung Galaxy Watch5 Series gets skin temperature-based Cycle Tracking

Samsung Electronics announced that skin temperature measurement is added to its existing calendar-based Cycle Tracking feature. Galaxy Watch5 and Galaxy Watch5 Pro users can now conveniently get even deeper insights to manage their menstrual cycles and overall health. Starting today, the new feature will be progressively released via Samsung Health app updates in Korea, the U.S. and 30 European markets.

As people search for ways to forecast their next period, they’re turning to temperature readings to help, since basal body temperature (BBT) varies by menstrual phase. BBT needs to be measured immediately after waking and prior to any physical activity or impact from surroundings. Getting accurate BBT readings requires measurement the first thing every morning, a process that can be inconvenient and sometimes even forgotten. Samsung’s new feature automates this process, making it easier and more convenient.

The Cycle Tracking feature is powered by Natural Cycles. Integrated with Samsung’s sensor technology, it enables users to track skin temperature changes, a good estimate of basal body temperature, during sleep right from their wrist. Galaxy Watch5 series uses infrared technology for more accurate readings, even if conditions of surroundings change. The advanced Cycle Tracking helps users track ovulation and better predict when their next period will begin.

To activate, users select Cycle Tracking in the Samsung Health app, add their most recent cycle information into the calendar and then turn on “Predict period with skin temp” in the settings. Readings collected over the prior month are displayed as a graph in Cycle Tracking, showing users their period as well as their predicted ovulation and fertile window. All collected data is encrypted and stored securely on the user’s own device, giving them more control over their data.

Cycle Tracking also evaluates symptoms entered into the daily log and provides relevant information and tips based on them, such as scheduling a day to relax to address fatigue or exercising gently to relieve premenstrual pelvic pain. In addition, Samsung Health app⁴ suggests useful content to help better manage holistic health during cycles, such as guided stretching or meditation classes to reduce stress and achieve a better night’s sleep — a key to a healthier self.
