Why Do Extremely Hot Weather Hurt People?

One of the most important effects of global warming is climate changes. Due to the changes in climate systems, longer summer seasons have been observed in recent years, when the air temperatures are very high. In addition to its effects on the whole ecosystem, extremely hot air currents pose a great danger to humans.

The human body loses heat in several ways. For example, sweating causes the body to cool. Also, blood circulation helps the body lose heat. As the air temperature rises, the heart begins to pump more blood. Due to the increase in blood flow, blood vessels expand. The blood, which begins to move closer to the surface of the skin, makes it easier for the body to lose heat.

However, excessive sweating that occurs when the air temperature is too high causes the body to lose too much fluid. In this process, some vital chemicals are lost in the realization of biochemical processes. In this case, dizziness, weakness, nausea, cramps in the muscles occur.

In cases where the air temperature is too high, the amount of heat absorbed by the body may be more than the emitted heat. In this case, the body temperature begins to rise. An increase in body temperature affects the central nervous system and blood circulation. If the body temperature exceeds 40 ° C, serious damage to the brain, heart, kidneys and muscles may occur and loss of consciousness may occur. This condition, called heat stroke, is a serious condition that requires medical attention.
