Normal body temperature is not a specific temperature point, but a temperature range. Clinical body temperature refers to the average deep temperature. The body temperature of mouth, rectum and armpit is close to the average deep temperature of human body, and the body temperature of rectum is the closest.
In a healthy state, if the diet is normal and the clothes are appropriate, the body temperature is relatively constant, that is, it is kept at about 37℃ (roughly between 36.2℃ and 37.2℃) and does not change with the change of the external environment temperature. The average normal body temperature is between 36 and 37℃ (underarm). If it exceeds this range, it is fever, 37.3 ~ 38℃ is low heat, and 38. 1 ~ 4 1℃ is high heat.
