Introduction
Temperature 37 refers to 37°C, and axillary temperature of 39 means 39°C under the armpit. Generally speaking, axillary temperature is more accurate than forehead temperature. When measuring, forehead temperature is obtained via infrared detection of surface body temperature, while axillary temperature is measured by direct skin contact. If body temperature continues to rise or other discomfort symptoms appear, it is recommended to seek medical attention promptly.

When measuring, forehead temperature is obtained via infrared detection of skin surface temperature, while axillary temperature is measured by direct skin contact. Since the forehead is constantly exposed to the external environment, it may be affected by environmental factors, leading to fluctuations in readings and reduced measurement accuracy. In contrast, the armpit is less influenced by external conditions, resulting in more reliable and consistent measurements; therefore, axillary temperature is considered more accurate.
When taking body temperature, it is recommended to use oral thermometers or ear thermometers, as these methods tend to be more precise. If using forehead or axillary thermometers, proper measurement techniques and potential environmental influences should be carefully considered to minimize errors. If body temperature continues to rise or other discomfort symptoms appear, prompt medical attention is advised.
