Usually, the body cools itself by sweating, but at times it’s not enough. As a result of this, the body’s temperature continuously rises. Major Heat stroke causes are as follows:

  • Exposure to the Sun – Especially on hot days, between 11am and 3pm.

  • Excess intake of caffeine and alcohol: The two are known to cause severe dehydration, which further affects the body’s ability to regulate body temperature. While these are not usually considered as heat stroke causes, but an excess intake of alcohol and caffeine can increase body temperature significantly.
  • Lack of proper ventilation – Working in hot environments, or in poorly ventilated, confined areas.

  • Heat Stroke causes Dehydration – This is one of the major causes of heat stroke. To keep the body temperature normal, it’s necessary that it stays around 37°C. The body cools itself by sweating, which accounts for 70 to 80 % of the body’s heat loss. In the case of dehydration, the human body is unable to sweat, which in turn leads to sun stroke illness.
