 note = {This study was carried out to find physiological reactions to cold, with reference to difference in the reactions between male and female human subjects. Experiments were made on six each healthy male and female students aged 19 to 25 years, in summer and winter. They wore standardized clothes and lay on a bed for 2 hours in an artificial climate room at about 10°C. Heat production, skin temperature, sublingual temperature, rectal temperature, urinary 17-Ketosteroids (17 KS), etc., were measured and the following results were obtained. 1. Heat production for females was lower than that for males, and decrease in the mean skin temperature for males due to the cold exposure was bigger than that for females. 2. On the interrelationships between heat production and mean skin tern-perature, no remarkable difference was noticed in the average values for males between summer and winter, but female students were weak to cold in summer, and contrarily, becam e stronger in winter. It seems that females have an ability of acclimatization to cold by the seasonal shift. 3. 17 KS for males increased at the cold exposure, but no remarkable change was seen for females in winter 4. From these evidences, the female subjects may be assumed to have a physiological adaptability to cold. This fact could be related not only to the sexual difference in physical characteristics such as skinfold thickness, etc., but also to that in feature and function of endocrine system.},
