The effects of two different types of clothing on seasonal warm acclimatization.

The work described in this paper investigates the effects of two types of clothing leaving the legs covered or uncovered, on seasonal warm acclimatization in women. Experiments were carried out to observe the differences in thermal responses between two groups of subjects who dressed themselves in trousers or knee-length skirts during the daytime for 3 months from April to June. Rectal temperatures in the subjects wearing skirts were found to be shifted to higher levels when the season gradually became warmer from spring to summer. The results suggest that the clothing type worn in daily life may play an important role in the seasonal warm acclimatization of thermal responses in humans.
