✦ Synopsis
Physiological measurements included mean skin, rectal, and body temperatures, mean heart rate, body heat storage, sweat loss and Physiologic Index of Strain. The performance measurements included tracking, mental arithmetic, visual-motor responses time, and auditory differentiation tasks. Head cooling significantly reduced the magnitude of all the physiological responses. The effect of head cooling on psychomotor performance was less impressive. The overall results indicate a lack of performance decrement as a result of the heat loads used here and no differential effects of head cooling on a subject's performance.
