Every morning and evening, there are certain differences in body temperature between different parts of the human body and between men and women. Normal body temperature has a relatively stable fluctuation range, but it is not constant. The oral temperature of normal people, also known as oral temperature, is about 36.2-37.2℃. Axillary temperature is 0.2-0.5℃ lower than oral temperature, and rectal temperature is also called anal temperature, which is 0.2-0.6℃ higher than oral temperature. In a day, the human body temperature is the lowest at 2-5 am and the highest at 5-7 pm, but the temperature difference within a day should be less than 0.8℃. In addition, women's body temperature is generally about 0.3℃ higher than that of men, and women's body temperature also changes regularly during menstruation. When the human body is in a healthy state, generally speaking, the diet is normal and the clothes are appropriate. At this time, the body temperature of the human body is generally constant, keeping at about 37℃, roughly between 36.2-37.2℃, and does not change with the change of the external environment temperature. The average normal body temperature of human body is between 36-37℃. If it exceeds this range, it is fever; If it is lower than 38℃, it is a low fever; If it is above 39℃, it is a high fever.
Within 24 hours, the temperature in the afternoon is slightly higher, and the temperature in the afternoon fluctuates by no more than one degree than that in the morning. After strenuous exercise, labor and mood swings, the body temperature will rise slightly, but generally the fluctuation range will not exceed one degree. Body temperature is a response to the surface temperature of the human body.
A normal person's temperature is 36 to 37 degrees, and the normal range is different with different measurement methods and parts. Its measurement methods are divided into armpit method, oral measurement method and anal measurement method. The normal range of oral measurement is 36.2 degrees to 37.2 degrees, and the normal range of anal measurement is about 37.5 degrees.
Body temperature is not static, it is influenced by mood, environment and activities. However, after rest and relaxation, the body temperature can return to normal again. If it exceeds the normal value, it is called fever.
