The body has got its owm mechanism to lose heat and keep the core temperature at its optimum normal. Radiation, convection by air currents, conduction and evaporation of water from the skin surface and sweating are the methods by which it is achieved. In summer when the surrounding temperature is higher than body, the body cannot pass inner heat to atmosphere and external heat tends to enter the body. If the sweating mechanism of the body is normal, then the increased blood circulation brings more and more water to the sweat glands in the skin and on the surface which gets evaporated because of high temperature externally. 1 gm of water which gets evaporated takes away 0.58. Calorie with it, cooling the body. If there is high temperature with high humidity or anything that interferes with the sweating mechanism, the body fails to lose inner heat and external heat keeps on entering the body raising body temperature to as high as 42 to 44 celsius which may cause brain damage and death. Such person needs to be shifted immediately to a well ventilated place and given cold sponging (not ice chilled, as it causes vasoconstriction to its maximum and further reduces heat loss). It is desirable that the enclosure is air conditioned. Such heat stroke clinics are kept ready in hospitals in areas with known high temperatures during summer.
