Investigation of the Effect of Cooling the Feet as a Means of Reducing Thermal Stress
Abstract
The purpose of this investigation was to determine if cooling the feet is as effective as cooling the hands in the alleviation of heat stress. Each of six volunteers dressed in chemical warfare (CW) protective clothing, sat for 120 min in an environment of 35 deg C and then immersed his feet in a water calorimeter for 20 min. Heat lost to the calorimeter was measured at water temperatures of 10, 15, 20, 25 and 30 deg C. The use of water-cooled socks was also examined under these environmental conditions. It was found that heat loss from the feet was comparable to that from the hands indicating that the two methods are equally efficient. Preliminary results indicate that the use of water-cooled socks may also be practical.
