Variation in mental performance under different levels of heat stress-induced dehydration was recorded in 11 subjects heat acclimatized to the tropicals. Dehydration was induced by a combination of water restriction and exercise in heat. The psychological functions--arithmetic ability, short-term memory, and visuomotor tracking--were assessed in a thermoneutral room after the subjects recovered fully from the effects of exercise in heat, as reflected by their oral temperature and heart rate. The results indicated significant deterioration in mental functions at 2% or more body dehydration levels.
对11名适应热带环境的受试者在不同程度热应激诱导脱水状态下的心理表现变化进行了记录。通过限制饮水和在高温环境下运动相结合的方式诱导脱水。在受试者从高温运动的影响中完全恢复后，于温度适中的房间内评估其心理功能——算术能力、短期记忆力和视觉运动跟踪能力，这通过他们的口腔温度和心率得以体现。结果表明，当身体脱水水平达到2%或更高时，心理功能会显著恶化。
