Why are we all afraid of the cold in winter, while the fighting people are still swimming in icy water?

Fear of cold or not is relative, the Russians due to geography is more resistant to freezing, but to the ice water swimming is also a minority, and the time is generally very short. People die of cold almost every winter in Russia, and many people in the north of the country go swimming in icy water in winter every year.

Swimming in icy water can face a big problem, which is the maintenance of human body temperature. When in icy water, the human skin and close to freezing water (close to zero degrees) close contact, the human body will quickly lose a lot of heat, in a relatively short period of time will lead to the limbs of the limbs of the blood vessel contraction, resulting in muscle stiffness and other problems, it is easy to lead to drowning, even if the water to maintain a high level of activity state can not make up for the loss of heat in the human body, for a long time will be due to the loss of temperature will result in chills, disorientation, cardiorespiratory function Adverse reactions such as cardiorespiratory failure, in the water these conditions are fatal, the person sinks into the water like a scale and drowns.

Russia due to geography, people living there may be more resistant to freezing, coupled with the public **** places have heating facilities, in the cold winter seems to be more resistant to cold, because of some of the wild operation of the Russians, we call "fighting nation", in fact, a little bit of a mean. There are also web videos of babies being drenched in ice water in the middle of winter by their mothers, which is unthinkable for us, but it does happen in Russia as a special event to celebrate a holiday.

Take a look at these pictures inserted in this article, although these children use cold water to wash their bodies, or go down to the ice water to swim, but usually have an adult on the side of the watch, not far away from the next is the warmth of the facilities, the short-term stimulation of the cold can also enhance the immunity of the human resistance. Swimming in icy water in the Russians and some winter swimming enthusiasts in the north of China, as is like the cold stimulus, but they are generally more experienced, try to swim in icy water, but will not stay in icy water for a long time, life or to be.

Since Russia's really too backward, some of the country are in the Arctic Circle, Russia's winter is not the vast majority of us can imagine, when Germany attacked Moscow, due to the cold caused a lot of trouble, last year, there is a news, Switzerland or Sweden, a girl walking outside at night, the body did not bring money can not hit the car, the result of freezing to death in the outside, and in fact, the temperature at that time seems to be The temperature of -10 degrees, and the temperature of Russia still can not be compared, almost is the gas into ice, those who are in the environment, the winter can not go out to go out, go out to the risk of death is mostly.

People's adaptability to the cold is actually still relatively strong, after all, human history through a few ice age, can be warmed with animal skin flames, but blindly faded clothing to stay in the cold environment, good point is exercise, to say the hard point is to die.
