Title The effects of local cooling on thermophysiological response in participants wearing dust-free garments
Bibliographic information 1998, Vol.4, No.1, p.57-67. Illus. 11 ref.
Abstract This study was designed to find the effects of clean-room garments (A), with, and without (B) a frozen gel strip (FGS), and half-naked clothing (brassiere and shorts; C) on workers' thermophysiological parameters and on the temperature and humidity within clothing. The heart rate, rectal, and skin temperatures, sweat rate and clothing microclimate were measured during 140min in 9 healthy females. Participants also made subjective ratings of thermal, humidity and comfort sensations. The main findings are that physiological parameters such as rectal and skin temperatures (chest and forehead), heart rate and sweat rate were clearly lowest with clothing C, intermediate with clothing A, and highest with clothing B; temperature and humidity within clothing were lower with clothing A than with clothing B; more than half of the participants reported a decreased thermal sensation by wearing clothing A. These results suggest that the usage of FGS could improve the heat load in lightly working participants wearing clean-room garments.
