Apple has released a new support document for Apple Watch Series 8 and Apple Watch Ultra with details on the new temperature sensor built into Series 8 and Ultra. In this detail, Apple talks about how the devices It takes them up to 5 nights to be able to determine the base temperature of the wrist from which they will take measurements of temperature variations.
Apple’s new watches, Apple Watch Series 8 and Apple Watch Ultra, They have two different temperature sensors, one on the back of the device that directly contacts our wrist and another just below the screen.. While the user is sleeping with the Apple Watch on, it takes temperature samples every 5 seconds. According to Apple, this is done to reduce the impact of ambient temperature on the measurements.
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 wrist’s baseline temperature and identify its nightly changes.
Apple also mentions that the “Sleep” feature of the Health application must be activated to track sleep with Apple Watch, as well as focus mode on rest for at least 4 hours for 5 nights. In this way, users will be able to check our body measurements in “Wrist Temperature” also in the Health app.
Apple, as usual, reminds us that Apple Watch is not a medical device and that it should not be used for medical purposes. It’s not a thermometer either. and it doesn’t measure temperature on demand, but rather temperature changes on our wrist. Additionally, wearing the Apple Watch loosely can also affect the quality of its temperature readings.
Apple promotes Keynote of the last day 7 that these new sensors allow us to improve our predictions as users about the time of ovulation (in case of female gender), but the supporting document suggests that keeping track of the temperature overnight also lets us know our overall health.
For anyone who doesn’t want to have this feature, you can turn it off in the apple watch app inside our iPhone, in the privacy and temperature of the wrist.
