Study on the effect of Ventilated Working Wear on physiological and psychological responses of construction workers– Part VIII

Relationship between water loss and skin temperature in artificial climate chamber

Abstract

: The effects in wearing ventilated work wear (VWW) and work hours were investigated. We measured water loss and skin temperatureof nine formworkers performing simulated construction work in an artificial climate chamber at controlled room temperatures of 34℃.It was measured that skin temperatures on thigh and lower leg with VWW was significantly higher than that without VWW, that was accord with the result that the contraction of peripherical blood was prevented by lowering dehydration with VWW. Evaporation rate (ER) and the rate of body weight less (BWL) in the afternoon were higher than those in the morning. By measurements, it is evaluated that amounts of dehydration by BWL were about 20% with VWW and about 50% without VWW higher than those by ER, respectively
