What effect does fever have on human body?

The increase of body temperature in pathological state is called fever (also called fever). There are many reasons for fever, one of which is that people are infected with pathogens, such as infectious diseases. According to the degree of temperature rise, fever can be divided into the following four categories: low fever (below 38℃), moderate fever (38 ~ 39℃), high fever (39 ~ 40℃) and ultra-high fever (above 4 1℃).

Fever has both advantages and disadvantages on human body. Fever within a certain limit is a physiological defense response of human body to resist diseases. At this time, leukocytosis, active antibody production, enhanced liver detoxification function and accelerated substance metabolism can improve the patient's resistance. These changes are conducive to eliminating pathogenic factors and restoring human health. On the other hand, high fever and long-term fever can cause some physiological obstacles of patients, such as irritability, delirium, hallucinations and even convulsions. When the body temperature exceeds 465438 0℃, the thermoregulatory center will lose its ability to regulate the body temperature; When the body temperature reaches 43℃, the patient will die of hyperthermia within a few hours. Because of the dysfunction of the circulatory system, the heart rate can be accelerated. Every time the adult's body temperature rises 1℃, the heart rate increases 10 times per minute, and children increase 15 times. Besides, it consumes a lot of matter and energy. These are all bad for the human body.
