According to Dr. Jolie Bookspan, cold acclimatization is a well-documented process of gradually increasing your resistance to cold through regular cold exposure. In Acclimatization to Diving in Cold Water, Dr. Bookspan noted examples of cold acclimatization: the native peoples of the African Kalahari, the Australian desert, and Tierra del Fuego in Chile.
In Chile, the truly hardy Yaghan people reportedly wore no clothes at all despite temperatures that were cold most of the time and cool at best.
The Yaghan women often dove into icy waters to retrieve the shellfish for the Yahgan men never learned to swim. They went to sea in all kinds of weather to look for thick kelp beds where shellfish and smaller fish hide.
Very strong women whose contemporary female counterparts in the modern marathon swimming world continue their tradition of swimming in the cold.
