研究了服装在冷暴露过程中和冷暴露后对躯干皮肤温度分布的影响。志愿者在5摄氏度的温度下冷却一小时，同时穿着旨在相对均匀分布的隔热衣服。他们使用了三种不同厚度的衣服。在寒冷暴露期间，热敏电阻测量皮肤温度后，衣服很快就从身体上部脱下，以便能够用热像仪研究裸露躯干前部的温度分布。然后研究了不同环境温度(5°C和20°C)下的温度分布随先前磨损的绝缘材料厚度的变化。温度分布的模式、躯干温度的范围和标准差都被发现是相对恒定的，尽管穿着的衣服的厚度不同，或者在由此产生的时变的平均躯干温度中。通常用于确定平均皮肤温度的躯干前部部位被发现位于躯干比周围区域更冷的部分。结论是，在本研究的条件下，脐部和乳头之间的位置可以更准确地估计平均躯干温度。
SummaryThe influence of clothing on skin temperature distributions of the torso was investigated during and after cold exposure. Volunteers were cooled for one hour at 5° C while wearing clothing designed to have insulation which was intended to be relatively uniformly distributed. Three different thicknesses of clothing were used. Following thermistor measurements of skin temperatures during the cold exposures, clothing was quickly removed from the upper parts of the body to enable thermographic investigations of the temperature distributions of the front of the bare torso. The evolution of temperature distributions were then studied at different ambient temperatures (5° C and 20° C) as a function of the thickness of the insulation which had previously been worn. The patterns of the temperature distributions, and the range and standard deviation of torso temperatures were all found to be relatively constant in spite of the different thicknesses of clothing worn or in the time-variant mean torso temperatures which resulted. The front torso sites normally used for the determination of mean skin temperatures were found to be on portions of the torso which were cooler than the surrounding regions. It was concluded that a site midway between the umbilicus and a nipple yields a more accurate estimate of mean torso temperature in the conditions of the present study.
