PlanetFear has a article on dealing with the cold. The article covers five topics:
Understanding the risks of cold injury including environmental factors such as air temperature, wind, dampness, and cold water immersion and individual factors such as activity level, hunger, thirst and fatigue, gender and physique, clothing and illness/injury.
