ARM WATER LOSSES UNDER DISPARATE ARM AND BODY THERMAL CONDITIONS

Abstract

The relative contributions of local and peripheral control of sweating were investigated by subjecting the left arms of two subjects to a different environmental temperature than the rest of the body. The effect of the above conditions on the cooling power of the arm was also studied. Arm water loss was found to be a function of the temperature of the arm's environment, as well as a function of the temperature of the body's environment. Maximum arm heat loss tends to occur when arm environment temperature equals body environment temperature, though in the cases where unusually high sweat rates for high arm environmental air temperatures were exhibited the general relationship was not reliable. Also, evidence is offered in support of the need for further experimentation in order to determine the effects of subject acclimatization and emotional sweating on the present results.
