| Abstract |
Thermoregulation is of considerable importance for humans in space and other extreme environments. A methodology is presented for evaluating heat flux from specific body zones, and for assessing individual differences in the efficiency of heat exchange from these body areas. The goal is to apply this information to the design of individualized protective equipment. A multi-compartment conductive plastic tubing liquid cooling and warming garment was developed. Inlet water temperatures of 8-45°C were imposed sequentially to specific body areas while the remainder of the garment was maintained at 33°C. The greatest amount of heat was exchanged by the thighs, torso, calves and forearms. Calculation of heat transfer rates standardized per unit tube length and flow rate instead of surface area covered showed that there was significantly greater heat transfer in the head, hands and feet. There was considerable subject variability in rates of heat transfer in the torso, thighs, shoulders, and calves and forearms. |
