Can humans adapt hot environments through habituation?

皮肤热感觉是体温调节的重要因素。然而，关于皮肤热敏感性与种族差异的研究报道很少。本研究的目的是检查居住在温带气候的热带原住民的皮肤热感觉。此外，实验在四个季节进行，以检查热感知的季节差异，这是设计不同种族使用的制冷或供暖系统时需要考虑的重要因素。热敏感性的季节差异只存在于日本的冷感觉中。日本人在夏季对寒冷的敏感性高于其他季节，而热带地区的人对寒冷的敏感性没有显著的季节差异。

Cutaneous thermal perception is an important factor for thermoregulation. However, there are few studies reported concerning cutaneous thermal sensitivity regarding ethnic differences. The purpose of this study was to examine the cutaneous thermal sensations of tropical natives residing in temperate climates. Furthermore, experiments were carried out in four seasons to examine the seasonal differences in thermal perception, which is an important factor to be considered when designing cooling or heating systems to be used by different ethnicities. The seasonal difference of thermal sensitivity was found only for Japanese cool sensations. Japanese had more sensitivity to cold in summer than other seasons, and tropical natives had no significant seasonal differences.
