What are the Causes of heat stroke?

Heat stroke is caused by many reasons:

Exposure to hot environment:

In this type of heatstroke, called non exertional heatstroke, being in a hot environment leads to a rise in core body temperature. This type of heatstroke mostly occurs after exposure to hot, humid weather, especially for prolonged periods. It occurs after most often older adults and in people with chronic illness.

Strenuous activity:

Exertion heatstroke is caused by an increase in core body temperature brought on by intense physical activity in hot weather. Anyone exercising or working in hot weather can get exertional heatstroke, but it’s most likely to occur when not used to high temperature.

In either type of heatstroke your condition can brought on by:

Wearing excess clothing which prevents sweat from evaporating easily and cooling the body
Becoming dehydrated by not drinking many fluids to replenish fluids lost through sweating or by urinating.
