In order to investigate water supplementation methods effective for the prevention of dehydration and heat stroke in the elderly, the water metabolism and thirst ratings of healthy elderly were studied before and after exposure to heat. This study was carried out over 2 yearsNine elderly males and 4 young control subjects participated in the acclimation study. In the elderly group, the total water intake increased by about 9.5%, and the total urine volume decreased by about 6%. Similar to the results seen in elderly subjects, the total water intake in the young control subjects increased by 2% after acclimation, but the decrease in the urine volume(18%) after acclimation was greater than that in the elderly group. Subjective thirst ratings after sweating with exercise-heat exposure increased after heat acclimation in both groups, but the increment of the rating was greater in the young control subjects (p<0.05).In the present study the elderly appeared to adapt to heat by increasing their fluid intake. However, the water loss due to perspiration and the thirst ratings after heat acclimation were lower in the elderly than in the young subjects, suggesting a slower water turnover in elderly people. Therefore, it is considered necessary to encourage the elderly to develop a deliberate habit of water intake.

为探讨预防老年人脱水和中暑的有效补水方法，对健康老年人在高温暴露前后的水分代谢和口渴程度进行了研究。本研究为期2年，共9名老年男性和4名年轻对照组参与了驯化研究。老年组总摄水量增加约9.5%，总尿量减少约6%。与老年受试者中观察到的结果相似，年轻对照受试者的总饮水量在适应后增加了2%，但适应后尿量的减少（18%）大于老年组。热习服后，两组受试者出汗后主观口渴评分均增加，但年轻对照组的增加幅度更大（p<0.05）。然而，由于出汗和热习服后的口渴等级的水分流失在老年人中低于年轻受试者，这表明老年人的水分周转较慢。因此，我们认为有需要鼓励长者养成有意识的饮水习惯。
