Abstract

This paper studies the relation of the evaporative heat loss to theraal stress in naturally acclimatized subjects under Indian conditions. The environmental conditions under which the subjects were made to perform light exercise ranged from 18.9Degree C E.T to 30Degree C E.T. The evaporative heat was found to be significantly correlated to the 1% level with the air and effective temperatures, with correlation constants of 0.79 & 0.80 respectively. The average rate of change of the evaporative heatloss with air temperature was 15.4 K cal/Hr/Degree C and with the effective temperature 9.1 K cal/Hr/Degree C.
