A body temperature of 36.3°C is within the normal range. Normal human body temperature is generally between 36℃-37℃, which can vary slightly depending on the measurement method. The axillary temperature of a normal person is between 36℃-37℃. If the axillary temperature is between 37.1℃-38℃, it is low fever; if the axillary temperature is between 38.1℃-39℃, it is moderate fever; if the axillary temperature is between 39.1℃-41℃, it is high fever; if the axillary temperature is over 41℃, it is super high fever. If the axillary temperature is found to be 35℃ when measured, it indicates a low body temperature. Therefore, 36.3℃ is a normal body temperature. The daily body temperature of a normal person may be affected by time, exercise, meals, external environmental temperature and other factors, but the fluctuation range usually does not exceed 1℃. When measuring axillary temperature, the head end of the thermometer should be placed deep in the armpit and clamped with the upper arm, and the reading can be taken in about 10 minutes. Before measurement, you should pay attention to wipe the sweat in the armpit, and make sure that there are no heat-causing or cooling items in the armpit, so as not to affect the accuracy.
