How long does not freeze
It has long been thought up and apply an interesting method of adaptation to frost, if I have to spend a long time on the street, for example in the winter walks. If leaving the house in the cold no longer go into a warm room, the body cools down a little faster, and discomfort from the cold feel stronger than if you go through the first minutes in the cold and then went into a warm room for 5-10 minutes and then further - for a long time in the cold. In this case, you will not experience the painful discomfort from the cold, and the walk will be much longer.
This is due to the inertia of the body at the time of reaction to the bitter cold. Stress constricts the capillaries of the skin from the cold trying to keep warm and reduce moisture conclusion that cools the body. At the same time run one additional heating mechanism - a slight increase in body temperature and increased heart rate and only need a little help your body.

Going out in the cold for a short time run the above process, but that did not stop him from giving blood narrowing capillaries in the skin to deliver more heat you need only 5 minutes to go in a warm room. The body of inertia does not have time to stop the additional heating, and again relaxed capillaries will not interfere with this. And now, once again leaving the cold you absolutely do not feel its searing breath. Your body will have time to quickly "get involved" at full capacity without additional loads.
