Reduction of Dehydration by Water Intake and Ventilated Working Wear at a Construction Site in Summer

Abstract

To obtain basic data for prevention of heat stroke during construction work in a hot environment, we analyzed the effects of wearing ventilated work wear (VWW) and the sweat rate (SR), the rate of water intake (RWI), and body weight loss (RBWL) in experiments of an artificial climate chamber and outside construction site in August. We supposed there is a limit to the amount of water that workers in a construction site can drink. Thus, we verified that RBWL increased with increasing WBGT mainly due to insufficient RWI, but could be partly decreased by using VWW, which decreased the SR.

Effect of ventilated workwear and working schedule on physiological and psychological responses of construction workers, no. 2: Actual investigation at an active construction site

“…Since the publication of the Japanese version of this paper, we have been conducting research regarding the effectiveness of VWW. Yamazaki et al analyzed the data obtained in this study in more detail and reported it in a Japanese version of the paper 8 . The analysis demonstrated that there is a limit to the amount of water that workers at a CS can drink, and it was verified that, in the CS setting, the BWL increased with increasing wet bulb globe temperature mainly due to insufficient rate of water intake (RWI).…”
