Our experience with temperature is generally subjective. Humidity, psychology of the person, even the state of humor, can affect the perception of cold temperatures warm. It is the same with the coldness of the wind. Temperature that we feel it is never true. The air in the immediate surrounding of the human body, warmed by body heat and lies about him in the form of a "cloak of air". This is what keeps people "warm". When the wind blows, the mantle moves away from the body, leaving the person exposed to the real temperature, which is a bit cold. The coolness of the wind affects the parts that produce and retain heat.
