Heat stroke is a disease caused by heat injury, mainly caused by a large loss of water and electrolytes when a person is in a hot environment, combined with problems with heat dissipation and a large accumulation of heat in the body. People in high temperature (>32℃), high humidity (>60%), poorly ventilated environment, prolonged heavy physical labor or high-intensity sports, military exercise, or because of fever, hyperthyroidism and the application of certain drugs can cause the body to generate a large amount of heat. High ambient temperature will also absorb a lot of heat from the outside environment because of high air humidity, obesity, wearing non-breathable clothes, lack of ventilation, and some people have problems with sweat gland malfunction and perspiration due to some diseases, which will cause the body to lose a lot of water and electrolytes, and a lot of heat accumulates in the body and directly burns various tissues and organs throughout the body. The body loses a lot of water and electrolytes, and a lot of heat accumulates in the body and directly burns all the tissues and organs of the body, causing heat stroke.
