A Laboratory Evaluation of Liquid Cooled Vests for Non-Combatants

Abstract

A laboratory experiment was used to assess the value of two commercial liquid cooled vests in alleviating some of the physiological and psychological effects of heat stress on human performance. For conditions of 55 C (dry bulb) and 55% relative humidity, both vests reduced the rate of rise of body temperature, heat storage rate, and mass loss due to thermoregulatory sweating of three subjects. All subjects stated that the vests provided some relief from heat stress, but no effects of heat stress on performance were demonstrated. It suggested that for noncombatant personnel, vests like those tested may provide a practical and economical way of alleviating some of the discomfort and adverse physiological effects of heat stress when environmental control is not practicable.
