heat

Normal human body temperature receptors are centrally regulated by temperature regulation, and make the heat production and heat dissipation process dynamic balance through nerve and humoral factors, keeping the body temperature in a relatively constant range. Fever refers to a situation in which a pyrogen directly acts on the body's temperature regulation center, the body's temperature center dysfunction, or various causes of excessive heat production and reduced heat dissipation, which causes the body temperature to rise above the normal range. Everyone's normal body temperature is slightly different and is affected by many factors (time, season, environment, menstruation, etc.). Generally, it is 36 to 37 ° C. To determine whether it is feverish, it is best to compare it with the body temperature under the same conditions. If you don't know your original body temperature, the axillary body temperature (testing for 10 minutes) can be regarded as fever if it exceeds 37.4 ℃.
