A body temperature of 37°C is normal. The most common ways to measure body temperature are to measure the axillary temperature, the temperature of the rectum, the mouth temperature, etc. The normal value of body temperature is a range, not fixed. The normal value of axillary temperature measurement in normal adults is 36~37℃. Clinically, a body temperature of 37.3℃ or more is called fever. Body temperature varies in different parts of the body, and it fluctuates with changes in mood, age, day and night, gender, and the environment, which is a normal physiological change. Regardless of which method is used to measure the body temperature, as long as the body temperature is less than the normal temperature of 37.3 ℃, it is a normal body temperature. Therefore, a body temperature of 37 ℃ is normal. If the body temperature appears feverish, it is recommended to go to the hospital in time, check the cause of fever and treatment.
