Abstract
Quickening of the sweating mechanism is cited as the major factor in acclimatization to heat. In dry heat, the mechanism permits lower skin and core temperatures with small change in rate of sweating. In wet heat, the quickening results in a markedly increased sweat production, which effectively assures a larger wetted area of skin and greater evaporative cooling. Little evidence is found that an increase in dermal conductance plays an important part in acclimatization to heat. The decrease in circulatory strain in dry heat after acclimatization can be attributed in large part to the lower skin temperature. In wet heat, the decrease seems to result primarily from the better balancing of the circulation against competing demands of muscle, vital organs, and skin.
