Sustaining Hydration in Hot Weather

Abstract

Maintenance of water and electrolyte balance is important for sustaining optimal performance. Dehydration produces greater thermal and cardiovascular strain during prolonged work; with the magnitude of added strain proportional to the magnitude of water loss. Dehydration also degrades morale and the desire to work. Body water deficits of as little as 2% normal body mass have been accompanied by impaired cognitive and physical performance. Furthermore, water deficits of 5% to 7% of normal body mass are generally associated with dyspnea, headaches, dizziness, and apathy. This presentation will summarize work that the U.S. Army Research Institute of Environmental Medicine has been doing to sustain proper hydration of soldiers during training.
