Acclimatization effect on the evening fall in core temperature under the influence of two types of clothing.

Abstract

This paper reports the effect of acclimatization on the evening fall in core temperature under the influence of two different types of clothing. Two groups of subjects dressed in either knee-length skirts or full trousers during the daytime for the three months from April to June. To compare the circadian rhythm of core temperature, the experiments were carried out before and after the three month program of acclimatization. It was found that the subjects who had worn knee-length skirts showed lower rectal temperatures during the nighttime and a bigger amplitude of circadian rhythm in July than in March.
