Apple Watch Series 8 & Ultra: How to Track Your Nightly Wrist Temperature

According to Apple, the Apple Watch Series 8 and Apple Watch Ultra versions may track your body temperature as you sleep to provide you "insight into your overall well-being." What it does and how to utilize it are both described in this article.

There are two temperature sensors in the Apple Watch Series 8 and Apple Watch Ultra. The other is right beneath the display, and one is on the back close to your flesh. Apple created it this way to increase accuracy by removing extraneous environmental influence.

These sensors can detect the temperature of your wrist, which can naturally change during the course of a night, once every five seconds if you wear your Apple Watch while you're sleeping. The data is then used by sophisticated algorithms to provide an aggregate for each night.

If you utilize Cycle Tracking, these readings can offer retroactive ovulation estimations and enhance period forecasts. They can also be used to provide you insight into your health if you are unwell by comparing them to your predefined baseline temperature.

What You'll Need

You must be at least 14 years old for your Apple Watch to monitor your wrist temperature at night. Additionally, you'll require the following:

  • An ‌Apple Watch Series 8‌ or ‌Apple Watch Ultra‌.
  • Setup for sleep mode with Track Sleep on Apple Watch turned on.
  • For around five nights, with at least four hours of sleep focus on.

How to View Your Wrist Temperature Data

  1. On your iPhone, open the Health app.
  2. Tap Browse, then tap Body Measurements.
  3. Tap Wrist Temperature.

If "Needs More Data" appears at the top of the graph, more nights of wearing your Apple Watch are required in order to determine your baseline temperature. The needed number of nights will be shown beneath the chart.

How to Disable Wrist Temperature Tracking

  1. On your ‌iPhone‌, launch the Watch app.
  2. Tap Privacy.
  3. Toggle off the switch next to Wrist Temperature.

Apple warns that the temperature sensor function is not designed for medical use and is not a medical device. Also keep in mind that certain physiological, lifestyle, and environmental factors may have an influence on the temperature data recorded by your Apple Watch.
