The causes of heat stroke

Heat stroke is a condition of excessive body temperature (above 40 C) and occurs suddenly mainly due to exposure to excessive outdoor temperatures over a long period of time, while the body has not been able to adapt to leading out. sweat leads to dehydration, electrolytes damage the central nervous system (thermodynamic) control system.

Heat stroke is often found in hard-working people: exercise, sports, football athletes, runner, workers who work in the hot weather for a long time. When overworked, our body produces a large amount of heat, and sweat is released to cool the body. However, when heat stroke occurs, the body's temperature control center can be disturbed, so a cooling mechanism does not occur. Just like that, the body's temperature continues to rise and puts the victim in a dangerous situation.

Heat stroke if not treated promptly can cause brain, heart, kidney and rhabdomyolysis damage. In addition, heat stroke can be caused by wearing a lot of clothes or a shirt that does not sweat while going out in the sun. Because many layers of cloth make it difficult for sweat to escape, soaking into the body makes it difficult to cool quickly.

In addition, heat stroke can occur in people who drink alcohol because it can affect the ability to adjust the body's temperature, especially when drinking alcohol goes out in the hot sun. heat stroke can also occur because the body is dehydrated by sweating.
