The cause of frostbite is exposure to low temperatures for long periods or exposure to very low temperatures for shorter periods.
That the priority of the work of the human body is to keep the body alive first and then attention to the work of body organs II. In cases of exposure to cold temperatures for long periods, the body sends signals to the blood vessels in the arms and the two men order them to contract, thus reducing blood flow to the skin, which increases the flow of blood to the body's vital organs and provides them with the necessary food. Preventing continued internal hypothermia by exposing less blood to external cold.
As the process continues, the limbs become more and more cold, the blood vessels expand for a while, then contract again, and the contractions and spasms rotate in the blood vessels to maintain as much as possible the limbs, but when the brain realizes that the human body is at risk of infection The body temperature decreases (ie, when the body temperature drops below 37 ° C) sends blood vessel orders to continue to constrict to prevent the return of cold blood from the limbs to the internal organs of the body. When this happens, the frostbite can be started.
