The latest Apple Watch Series 8 and Ultra came with a new temperature sensor. These watches can measure your body temperature with the new sensor. And just like other health tracking features of the Apple Watch, temperature monitoring is also very accurate on the latest Apple Watches. In this article, let’s check out the top three reasons why Apple Watch Series 8 and Ultra temperature sensors are more accurate.

What is Temperature Sensor in Apple Watch?
The Apple Watch Series 8 and Apple Watch Ultra temperature sensors can measure your body temperature. You can monitor your body’s temperature and variations happening in temperature the throughout the night.
It tracks your body temperature during sleep and compares it with the baseline temperature of your body to show the variations and changes that happened in the temperature.
The Apple Watch temperature sensor is also helpful for female cycle tracking. It can predict the ovulation time and the period cycle of women and alerts them to be prepared for it.
Why Apple Watch Series 8 & Ultra Temperature Sensor is Accurate?
Regular budget smartwatches with body temperature such as the Boat Watch Mercury, Noise Caliber, and more use a regular skin temperature sensor to measure body heat. However, they’re not only very slow but also lack accuracy.
On the other hand, Apple has not only differentiated itself in terms of the overall body temperature sensing setup but also brags an impeccable accuracy. Here are the main reasons why the temperature sensor on the Apple Watch Series 8 and Ultra is accurate enough to be trusted. Read on.
1. Apple Uses Two Temperature Sensors
The Apple Watch Series 8 and Ultra use two temperature sensors embedded in a single watch. One sensor is present at the back crystal, near your skin and the other one is embedded under the display.
The design reduces the bias in temperature vis-a-vis the outer environment and yields more accurate data. The two sensors work in conjunction simultaneously and combine advanced algorithms to help measure your body temperature.
2. Measures Temperature Throughout the Night
The Apple Watch Series 8 and Ultra record your body temperature while you are sleeping throughout the night. Apple says the sensor records the temperature data every 5 seconds during your sleep. And all of the data is then synced to Apple Health
You can check all the variations that happen in your body temperature during sleep in the Apple Health app. It also shows a detailed graph along with the average increase or decrease in the baseline temperature.
3. Measures Smallest Temperature Changes
The temperature sensor on the Apple Watch can measure the smallest temperature changes. It can measure any change in your body temperature from as low as 0.1 degrees Celcius.
This thing can help to provide more accurate temperature data even if the value is in points. For instance, it will show the exact body temperature value like 34.3 degrees Celcius or something, and will not round off the value by showing 34 or 35 degrees Celcius.
Uses of Apple Watch Temperature Sensor
The Apple Watch temperature sensor can not only check if you have a fever but also helps with other uses, as shown below.
- Checks for Fever: The Apple Watch temperature sensor can monitor your body temperature and tells whether you have a fever or not. It creates an average baseline temperature of your body after using it for a few days and then compares the rise and fall in temperature. Based on this, it alerts you if you are having a fever.
- Predicts Female Ovulation and Period Cycle: The temperature sensor on the Apple Watch is very helpful in female health tracking. It can predict the ovulation time and the period cycle of women every month based on the temperature changes in the body. It is possible because the women’s body temperature increases when the period cycle and ovulation time are near, and the Apple Watch compares it with normal basal body temperature.
Frequently Asked Questions
Q. What is the Basal Body Temperature in Apple Watch?
As per MayoClinic, basal body temperature is the temperature of your body when you’re at rest. It translates to the body temperature when you are sleeping or in a resting state.
Q. Can Apple Watch Detect Air Temperature?
No, the Apple Watch cannot detect air temperature because it comes with two temperature sensors at the back of the watch and behind the display which need to be in contact with the skin to measure body temperature only.
Q. Does Apple Watch Series 7 or SE 2 Have a Temperature Sensor?
No, the temperature sensor is only available in the Apple Watch Series 8 and Apple Watch Ultra for now.
Q. Can the Apple Watch Temperature Sensor Be Used for Birth Control?
No, Apple has stated that the cycle tracking app should not be used as a form of birth control. It is only for an indication of period cycle tracking and ovulation prediction for personal information only. It is not a medical device and should never be treated as one. The same holds true for the ECG feature.
Wrapping Up
These were the three reasons why the Apple Watch Series 8 and Ultra temperature sensors are more accurate compared to traditional smartwatches. We particularly liked that Apple didn’t limit it to measuring just the skin temperature. Stay tuned with WearablesToUse for more informative articles!
