Abstract: | Dynamic changes in local sweat rates (Sw) and local evaporation rates from clothing (Ecl) have been observed during hot exposure. Four young male subjects wearing a cotton T-shirt and half shorts were exposed to 40 °C/50% for 1 h following exposure to 28 °C/50% for 30 min. Amount of water absorbed in clothing (Msw), clothing surface temperatures (Tcl), local heat flow rates, skin temperatures, body weight, rectal temperature, Sw and Ecl were continuously measured. Upon exposure to the heat, decrease in heat gain to the skin was observed as opposed to increase in Sw, Ecl, Msw and heat gain to the clothing surface. |
