Pediatric heat stroke and fever

Humans are constant-temperature animals. Regardless of how much the outside temperature changes, the body temperature can be maintained at about 36 to 37 ° C through the regulation of the hypothalamic body temperature regulation center. However, the human body has a certain tolerance limit to the increase in temperature and duration of the surrounding environment. If the human body is exposed to high temperature for a long time, the body loses the function of adjusting compensation. In the high temperature, high humidity environment or under the direct sunlight for too long, leading to a series of symptoms such as temperature regulation dysfunction, water and electrolyte metabolism disorders and nervous system damage, it is heat illness or heat fever (summer fever). Generally speaking, those with acute onset and severe illness are called heat stroke. Onset is slow, symptoms are mild, and those with longer duration are called summer fever. In recent years, due to the improvement of living standards and the large-scale application of air conditioners, its incidence has decreased significantly.
