The mechanism of heat stroke fever has three points: the first point, because the thermoregulatory center has abnormalities, the thermoregulatory center is not able to correctly identify the degree of heat and cold in the body, and also cannot make the body make corresponding adjustment measures in time to adjust the cold and heat inside the body, so when encountering a high temperature, high heat environment, the body is assimilated by the surrounding environment, resulting in difficulty in heat dissipation and fever. The second point, the body’s heat dissipation function is weakened, working and living in a high temperature, high humidity environment, or wearing a lot of clothes that do not breathe, will lead to the body inside the heat dissipation function will also be weakened, it is easy to be assimilated by the surrounding environment, resulting in fever. The third point, drink less water, if in a high-temperature, high-heat environment, the body does not have enough liquid to sweat, will lead to the body’s heat dissipation function is weakened and fever.
