Our support team searches for useful product information and answers to frequently asked questions. If you find an inaccuracy in our frequently asked questions, please let us know by using our contact form.
I just took my temperature but what is actually considered a 'healthy' body temperature? Verified
This partially depends on the body part where the temperature was taken. The following can be considered healthy: Forehead 35,8 to 37,6 °C, Ear 36 to 37,8°C, rectally 36,3 to 37,8°C and orally 36 to 37,4°C.
This was helpful (952) Read moreWhat parts of the body are best to measure body temperature? Verified
This depends on the thermometer. Some thermometers are designed for use on specific parts of the body. With a regular thermometer, rectal usage is the fastest and most accurate way to measure body temperature.
