本文所述的观测是在研究热带气候对越南人和日本人的影响时进行的。我们测量直肠和皮肤温度，每10分钟为26小时在6个越南人和6个日本。实验已进行了2个炎热的月份，6月和7月1999年和2000年在河内，越南。环境温度范围为33至36摄氏度。结果表明：1）越南人的大腿、前臂和手部皮肤温度在白天显著高于日本人。这将是对温暖的环境温度的生理反应，这有利于身体热量的消散。2)越南人白天的平均直肠温度显著高于日本人，而夜间显著低于日本人。3)越南人直肠温度的平均波动幅度为1.26 ℃，明显大于日本人。较高的核心温度，这是积极调节下温暖的温度，似乎有适应意义，从而减少了水分的消耗，像骆驼在沙漠中。一个更大范围的振荡在热带越南人可能有生态意义的有效驯化在温暖的环境中，这表明核心温度的设定点可以显示更大范围的振荡。
The observations described in this paper were made during a study of the effects of tropical climate upon Vietnamese and Japanese. We measured rectal and skin temperatures every 10 min for 26 hrs in 6 Vietnamese and 6 Japanese. The experiments have been conducted for 2 hot months, June and July 1999 and 2000 in Hanoi, Vietnam. The ambient temperatures ranged from 33 to 36degreeC. The results obtained are summarized as follows: 1) Skin temperatures at thigh, forearm and hand during the daytime were significantly higher in the Vietnamese subjects than in the Japanese ones. It would be physiological reactions to warm ambient temperatures, which is advantageous for dissipation of body heat. 2) The average rectal temperature during the daytime is significantly higher in the Vietnamese than in the Japanese, while significantly lower at night. 3) Average range of oscilation of rectal temperature was 1.26degreeC in the Vietnamese, which was clearly greater than in the Japanese. The higher core temperature, which was actively regulated under warm temperature, seemed of adaptive significance, resulting in the reduction of water consumption like camels in the desert. A greater range of oscillation in tropical Vietnamese people might have ecological significance for efficient acclimatization in the warm environment, suggesting that the setpoint of core temperature could show a greater range of oscillation.
