Abstract : Cold-acclimatization in animals is accompanied by increased resistance to cold injury. The induction of cold acclimatization in man subsequent to natural and ar ifici l exposure to cold is reported. Indices measured were oxygen consumption, skin and rectal temperatures, and shivering. In all cases shivering was decreased or extinguished by the cold exposure. Oxygen consumption decreased only in those subjects who could be presumed to be minimally acclimatized. Skin temperatures were unaffected or only minimally affected. Rectal temperature decreased only if the cold exposure was sufficiently severe. These changes once produced were not reversed by heat acclimatization and were well retained depending on the degree of cold acclimatization achieved. T e de onstration of a physiological cold acclimatization in man suggests the possibility of its use as a protective mechanism in human cold injury. (Author)
