The thermoregulatory responses of a French doctor, Jean-Louis Etienne, were examined in a standard cold test before and after his journey to the North Pole, to investigate whether general and/or local cold adaptation had occurred. The two tests were carried out in a climatic chamber for 2 h at rest (dry bulb temperature, 1 degree C; relative humidity, 40%; wind speed, 0.8 m.s-1). After his journey, Etienne showed a general hypothermic-hypometabolic adaptation, i.e. a decrease in rectal temperature (Tre) and metabolic heat production (M), and an increased local skin temperature of the extremities. Between the two tests, a change occurred in the relationship between tympanic temperature (Tty) and M. During the post-journey cold test, Tty [as representative of the central nervous system (CNS) temperature] increased while the decrease in Tre was accelerated, probably due to a redistribution of blood volume towards the CNS. Such a mechanism would protect the central core with special reference to the CNS.
法国医生让 - 路易·艾蒂安（Jean-Louis Etienne）在前往北极前后，于标准寒冷测试中接受了体温调节反应检查，以探究是否发生了全身性和/或局部性冷适应。两次测试均在气候舱内静息状态下进行2小时（干球温度1摄氏度；相对湿度40%；风速0.8米/秒）。旅行之后，艾蒂安表现出全身性低温 - 低代谢适应，即直肠温度（Tre）和代谢产热（M）降低，以及四肢局部皮肤温度升高。两次测试之间，鼓膜温度（Tty）与M的关系发生了变化。在旅行后的寒冷测试中，Tty [作为中枢神经系统（CNS）温度的代表]升高，而Tre的下降加速，这可能是由于血容量重新分配至中枢神经系统所致。这样一种机制将特别针对中枢神经系统保护中央核心。
