Ten men occupationally exposed to cold and ten office workers participated in the study. Reactions to immersion of the hands in cold water (+ 10 degrees C) for 2 min were studied during the following 30 min at two different ambient temperatures, 10 and 20 degrees C. Hand skin temperature was recorded in thermograms, and the subjects rated cold sensation and pain. Considerable interindividual differences in hand skin temperature reaction were found in both groups. On the average the occupationally exposed workers had a somewhat higher hand skin temperature than the office workers during the recovery period in the 10 degrees C ambient temperature, although the difference did not reach significance. The office workers rated significantly greater cold sensation as a result of the cold immersion, especially during an ambient temperature of 10 degrees C, and the frequency of pain ratings was higher for this group. The results suggest that cooling among the occupationally exposed workers at work was not severe enough to produce physiological adaptations, although some psychological adaptation was indicated.
十名职业性暴露于寒冷环境的男性和十名办公室职员参与了这项研究。在接下来的30分钟内，研究了在两种不同环境温度（10摄氏度和20摄氏度）下，双手浸入10摄氏度冷水中2分钟后的反应。通过热成像图记录手部皮肤温度，并让受试者对冷感和疼痛进行评分。在两组中均发现手部皮肤温度反应存在相当大的个体差异。平均而言，在10摄氏度环境温度下的恢复期，职业性暴露的工人手部皮肤温度略高于办公室职员，尽管差异未达到显著水平。由于冷水浸泡，办公室职员的冷感评分明显更高，尤其是在10摄氏度的环境温度下，并且该组疼痛评分的频率更高。结果表明，职业性暴露的工人在工作时的降温程度不足以产生生理适应，尽管有迹象表明存在一些心理适应。
