The body normally generates heat as a result of metabolism and is usually able to dissipate the heat by radiation of heat through the skin or by evaporation of sweat, explained Medicine Net.
The health site added: “However, in extreme heat, high humidity, or vigorous physical exertion under the sun, the body may not be able to sufficiently dissipate the heat and the body temperature rises, sometimes up to 106 F (41.1 C) or higher.
“Another cause of heatstroke is dehydration.
“A dehydrated person may not be able to sweat fast enough to dissipate heat, which causes the body temperature to rise.”
