How Does The Body React to The Heat?


Heatstroke caused by the condition of the human body which is exposed to a very hot condition. Usually, this is often the case for athletes and people who have to work outside in summer.
The occurrence of Heatstroke can not be predicted because it occurs suddenly. It also rises uncontrollably in body temperature. This reaction caused when the human body not being able to replace fluids which have to be replaced. Then, dehydration occurs and it causes a decrease in blood.

In this circumstances, the body must choose where it has to give the blood, whether to the main organs such as liver, kidneys, brain, and so on or to the skin. The main organs are more important so they will receive the blood. Because of the drop in fluids, as consequence, the body can not produce the sweat and cannot cool itself. This situation becomes complicated. Since the skin gets no blood supply, excess heat cannot be released through the skin. The lack of blood supply and the inability to sweat together cause the body to overheat.
Heatstroke must be treated immediately or it can cause permanent injury and chances of survival can be slim.
