Even healthy people who do not have medical history are also not safe. If they train intensively when the weather is very hot, and force themselves beyond, the body can give up and experience thermal attacks.
The same applies to people who work a lot in the sun, for example, road builders.
When the weather is hot, our skin flows more blood, and the body tries to cool through the skin and blood circulation.
We begin to sweat, and the evaporation of sweat helps to reduce body temperature. But at extreme temperatures, this system of a natural heat regulator may not function. The body can lose from half to several liters of liquid per day, and 99 percent of sweat is water.
Our main body temperature regulator is Ecrine sweat. This iron is located under the armpits, palms, as well as on the forehead.
Each gland has a diameter of about 0.4 mm. The human body has from two to four million glands Ecrin. Sweat is made at the end of the gland in the form of rolling woolen yarn. Through a small channel, sweat flows to the surface of the skin and forms small granules.
While this system operates, the body can balance its own temperature. But if it cannot function – for example, when the sun is so fierce – the situation can be dangerous.
In the sun, the head becomes too hot from the direct effect on the sun. The initial symptoms are usually in the form of headaches, a hard neck, extreme fatigue, and sometimes accompanied by nausea and vomiting.
This is because the brain membrane (mening) is irritated from excessive heat and can cause aseptic meningitis, which is an inflammation of the mucous membrane of the brain, which is not caused by bacteria.
The suffering can feel dizziness, experience confusion, even fainting. In such cases, it is necessary to immediately receive medical care.
The first step that needs to be taken is to move the patient to a cool place, lie on the position of lying on his back and raise the head and upper body. Cold compression on the neck and other parts of the body can help the patient. Patients should also drink a lot to restore the balance of body fluids.
