Apple Watch Series 8 will alert its users if they have a fever

The upcoming Apple Watch would be able to detect a rise in body temperature

The new Apple Watch Series 8 will have a body temperature sensor that will let the user know if a person is running a fever. The upcoming Apple Watch would be able to detect a rise in body temperature and then ask you to confirm using a thermometer, reports Bloomberg's Mark Gurman. Previous reports suggest that the sensor could also be used for fertility tracking -- shifts in body temperature could help individuals determine when they're more likely to get pregnant. The watchOS 9 will also bring new features, such as the Workout app, sleep stages, a first-of-its-kind Afib History feature, and an all-new Medications app.

The company said watchOS 9 brings sleep stages to the Sleep app and a new FDA-approved AFib History feature which provides deeper insights into a user's condition. With watchOS 9, users diagnosed with Afib can turn on the Afib History feature and obtain important information, including an estimate of how frequently a user's heart rhythm shows signs of AFib, which provides a deeper insight into their condition. The US Food and Drug Administration (FDA) last month approved a software developed by Neurology company Rune Labs that helps people with Parkinson's disease track their symptoms through Apple Watch.
