This allows more warm blood to flow near the surface of the skin, where the heat can be lost to the air. Although heat stroke mainly affects people over age 50, it also takes a toll on healthy young athletes. Evaporation (or sweat) is another way to lose heat from the body. Cells and nerves in the body become damaged. If it rises or falls, a range of very efficient physiological mechanisms come into play. About 80% of the energy produced by working muscles is heat, so any activity will increase the amount of heat the body has to lose.

Such acclimatization on the playground or outdoor places like construction sites, or mines, should take place under close supervision by experienced trainers/safety managers; the new sportsperson/worker should have standing permission to withdraw to cooler conditions any time symptoms of intolerance occur.

But the primary defenses are health and wealth. Make it possible for everyone to access cool air and water on a hot day. If the victim starts shivering because his/her body is trying to raise the core temperature, slow down the cooling treatment because this can result in an uncontrollable downhill fall towards dangerously low temperatures (hypothermia). Keep athletes and laborers out of the sun. And wealth protects you from having to encounter it, really, in the first place. For the relatively wealthy, air-conditioned set, punishing heat is less a killer than an inconvenience.

The kidneys stop working, normal blood clotting is impaired, the heart muscle can be damaged and skeletal muscles start breaking down.

At that point, blood vessels constrict at the body’s periphery, causing the lips and skin to become dry and flaky. EHS happens when the individual’s capacity to dissipate or drive away the heat produced by overactive muscles falls short. We frequently read news about young men (and women) collapsing and dying with no apparent reason when made to undergo severe physical excretion for endurance tests during recruitment in the Indian police force or military.
