It is a physical response of your body to the cold. Although you cannot see them, tiny blood vessels called capillaries are under your skin. Your body recognizes the danger of the cold freezing your skin and killing the cells, and it routes more blood through the capillaries trying to keep them warm enough.

Because the homoeostasis process in the body has to respond to maintain the body temperature and the response of the body is to increase the temperature of the body through shivering and increasing red blood circulation (causing the redness).

Your face turns red because your blood goes to your face to keep your skin warm.

AND also how the sun reflects off white (snow) and onto your skin...causing somewhat a sunburn like the sun would do on a normal really sunny day. hard to believe but its true.

extra blood that your body sends there to keep it warm.
