Things wouldn't be so bad if the brain showed a little tolerance for heat. Instead, he arranges his demonstrations and demonstration parades, inviting only a negative reaction of the whole organism. What makes him rage? Why does the brain rebel? Read the brain confession at estet-portal.com.
Why does the brain resist heat?
The center of temperature perception is located in the brain, or rather, in the hypothalamus. At an air temperature of 16-25 degrees, the receptors of this department function quite normally, but at a temperature of 28 degrees, this part of the brain gradually begins to lose its tolerance. Air temperature exceeding 30 degrees can cause pain and heat shock. With a general body temperature that has reached 43 degrees, brain death occurs. Why is the brain so critical of heat?
The fact is that when the body is critically heated, proteins begin to change their structure, which has a devastating effect on all cells of the body. As a result, the brain dies first. Nevertheless, people willingly visit saunas, baths, travel to tropical countries and return from there alive, with an absolutely unharmed brain. How is this possible?
How does the body adapt to heat?
It is known that the human body is able to tolerate temperatures of 90 degrees, however, this vital property ends in death after the 20th minute. It is also worth noting that 70% of people are able to survive at a body temperature that has reached 43 degrees, but only if the right medical care has been provided. This indicates that under certain conditions the body has the ability to adapt to high temperatures.
A special system of thermoregulation helps with this. It consists of blood vessels, sweat glands and skin.
The skin serves as a kind of barrier that allows the body to maintain a normal temperature under the influence of heat from the environment. The sweat glands, in turn, cool the skin by moisturizing it with their secretions. To maintain health, it is necessary to replenish this water and salt balance, since the main components of sweat are salt and water. It is for this reason that during the heat a person wants to consume more water and cold foods, and sometimes even pulls on pickles. In addition, a decrease in appetite during the heat is also considered the norm. The metabolic process warms up the body somewhat, knowing this, the brain and the body as a whole are in no hurry to starve in order to maintain their healthy state.
In the event that the body temperature exceeds the norm, the body urgently needs medical assistance to normalize thermoregulation. This is due to the fact that the body itself cannot eliminate the cause of the increase in its temperature, since it is associated with the development of the disease. However, it is important to keep the body hydrated by rubbing the body with water at room temperature. In some cases, doctors recommend wiping parts of the body with ice. Ice must be wrapped in a cloth bag. They need to treat those parts of the body where the blood vessels are located closest to the skin. These include the groin, neck and armpits. This helps to cool the body somewhat and minimize damage to it.
Interesting facts about a hot body
It is known that the human body tolerates heat much better in a dry climate than in a humid one. This is due to the fact that in dry climates, sweat-moisturized skin dries much faster, which helps it cool down.
During difficult physical work in the heat, a person loses about 10-12 liters of water and 20 grams of salt, which is about two teaspoons.
A European, finding himself in a tropical climate or in the desert, suffers one week of acclimatization, which is accompanied by increased weakness. After, his body returns to tone.
With intense physical exertion, the internal temperature of the muscles can reach 42 degrees, which does not pose a danger to general health.
Being in a cold room without clothes, body temperature can drop to 27 degrees.
Body temperature fluctuates throughout the day. The lowest temperature is recorded at dawn and can exceed the norm by one degree by the end of the day.
