Abstract
The rate of loss of acclimatization to heat when men are withdrawn from work in hot conditions in a mine to work in cool conditions for periods of 1, 2, and 3 wk., both in summer and in winter, is examined. Samples of 20 men who had been working in a hot area of a mine were withdrawn and subjected to a 4 -day period of acclimatization. This had the effect of bringing all the subjects to the same state of acclimatization. There was a progressive rise in rectal temperature and heart rate and fall in sweat rate in the groups exposed to 4 hr. of moderate work at 90[degree]F WB after being in cool conditions for 1, 2, and 3 wk. There was no significant difference between summer and winter values. The values for these physiological measurements in a control group of unacclimatized men were significantly higher in winter than in summer. The practical implication of these results is that men who have been away from work in hot conditions for 1 wk. should be reacclimatized for 1 day before going back to work in hot conditions.This publication has 1 reference indexed in Scilit:
