The cause of heatstroke is mainly when the weather is hot or cold.

Heatstroke refers to the imbalance of body temperature regulation caused by high temperature, excessive accumulation of heat in the body, resulting in damage to nerve organs. In the classification of heatstroke, it belongs to severe heatstroke. The disease usually occurs in hot and humid summer. In hot weather, once you are sweating and unconscious, you should pay attention to cooling down. If someone is in a coma at high temperature, immediately carry the comatose person to a ventilated and cool place and pour cold water to reduce the comatose person's body temperature. Then, the temperature change is continuously monitored. If the high fever lasts about 40℃, immediately send it to an experienced hospital for fluid resuscitation treatment. Never underestimate the common heatstroke and delay the treatment time.

Pathological etiology

Because the continuous sultry heat will reduce the heat dissipation function of human skin, while infrared rays and ultraviolet rays can directly penetrate the skin and reach the deep muscle, and the heat in the body cannot be emitted. At this time, heat is concentrated in organs and muscle tissues, causing dry skin, rising muscle temperature, causing sweating, and then damaging the central nervous system. Thereby affecting the functions of various organs and tissues of the whole body. Patients with local muscle spasm, high fever, no sweat, dry mouth, coma, elevated blood pressure, cough, asthma, dyspnea and even respiratory failure are the most serious heatstroke. Physical activity or non-physical activity at high temperature may lead to this severe heatstroke. If not treated properly in time, the mortality rate is as high as 40% to 50%.
