The normal human body temperature is 36.0℃-37.0℃, so 36.2℃ is a normal body temperature. The normal body temperature is not fixed, but can fluctuate due to gender, age, day and night, exercise, emotions and so on. Generally, the body temperature of women is slightly higher than that of men, and the body temperature of women in the premenstrual period will be mildly increased, mainly related to the secretion of progesterone. Children have a high metabolic rate and their body temperature can be slightly higher than that of adults; older people have a low metabolic rate and a low body temperature. During the day, the body temperature is usually lowest in the early morning from 2 to 5 and highest in the afternoon from 5 to 7, which is related to the long-term lifestyle of human beings. In addition, sympathetic excitation during emotional stress and skeletal muscle contraction during exercise can also cause a slight increase in body temperature. However, the above changes are usually within the normal range. If the body temperature exceeds that range due to various factors, it is feverish. It is recommended to avoid exertion, rain and cold, regular rest and rest, reasonable diet, and if fever occurs, go to the Infectious Diseases Department of the hospital in time.
