What is the normal temperature range when measured under the armpit?

The normal temperature range for axillary (underarm) measurement is generally between 36°C and 37°C. The detailed analysis is as follows:

Axillary temperature measurement is a non-invasive, convenient, and quick method used to detect changes in body temperature. The normal range obtained from this method falls between 36°C and 37°C. However, it should be noted that a healthy person's body temperature is not constant; it may fluctuate by 0.5 to 1°C throughout the day due to activities, eating, or exercise, but usually remains within the 36–37°C range. If the axillary temperature exceeds 37°C, it indicates fever. Typically, a temperature between 37°C and 37.9°C is considered low-grade fever; between 38°C and 38.9°C is moderate fever; and above 39°C is classified as high fever. If abnormal body temperature occurs, it is recommended to seek medical attention promptly and receive symptomatic treatment under the guidance of a qualified physician.

In daily life, pay attention to keeping warm and avoid getting chilled. Also, avoid consuming spicy or irritating foods, which may hinder recovery.
