This is what heat waves can do to the human body

Weather of Arabia - With the onset of summer and rising temperatures, most people resort to several means to cool the atmosphere and avoid the harmful effect of heat on the body, and temperatures may sometimes rise to levels that are difficult for many to bear, but what is really happening in the human body with the rise in air temperature? ! Why does the intense heat create this uncomfortable sensation? And why is heat sometimes dangerous?

How does hot weather affect the human body?

The human body absorbs heat from the surrounding environment, and when the body temperature begins to rise, the body automatically does a number of things to get rid of that excess heat, but your body may lose this ability when the temperature reaches high levels, or when exposed to heat for long periods.

Heat stroke is one of the most dangerous symptoms caused by the body's inability to regulate its temperature, as heat stroke occurs when the body temperature reaches more than 40 degrees Celsius, and heat stroke can cause death if no medical intervention occurs in time.

What happens to the body when you get heat stroke?

• stop sweating

During heatstroke, the body's functions stop working, as the hypothalamus in the brain shuts down the body's natural cooling system (i.e. sweating), and without sweat the body loses the ability to control its temperature, causing a devastating chain reaction that can be It is fatal if medical intervention is not done in time.

• brain enlargement

Heat stroke affects the nervous system, causing the brain to swell, causing headaches and even seizures in the most severe cases. The sufferer also suffers from disturbances of consciousness, including confusion, delirium, hallucinations and even loss of consciousness.

• Low pressure and heart rate

The cardiovascular system is also affected when heatstroke occurs, as blood pressure and heart rate drop irregularly, which increases the risk of heart failure caused by high blood pressure. Small blood clots can also form in blood vessels, preventing healthy circulation and cutting off blood flow to other parts of the body.

• Kidney dysfunction

Regarding the renal system, heat stroke reduces urine production and causes a condition known as "acute tubular necrosis," in which the kidneys fail to receive enough oxygen-rich blood to support proper function. Kidney failure.

Other factors that increase the risk of hot weather on the human body

• High humidity: High humidity in the atmosphere increases the effect of hot weather, as the body's ability to get rid of heat through sweating diminishes.

• Age: Age plays a big role in the body's ability to regulate heat. Young children and the elderly are not only more susceptible to high temperatures due to their weak nervous system, but may also have more difficulty avoiding hot places. In a heat wave, if you are elderly and your air conditioner is not working, your ability to repair it may diminish, so you may be exposed to extreme heat for a longer period of time.

• Effort: Effort is an important factor to consider as well. Strenuous exercise increases the risk of heat stroke, especially if the individual is not accustomed to training in hot weather.
