This study assessed the effects of clothing and air temperature combinations on workplace productivity and physiological response. Ten male Japanese subjects were exposed to six combinations of clothing (0.3 clo and 0.9 clo) and air temperature (16°C, 26°C, and 36°C) during which cognitive performance (Bourdon and calculation tests), manual motor performance (finger-tapping test), and physiological responses (heart rate, blood pressure, and skin and oral temperatures) were measured. Both cold exposure and lower clothing levels likely increased the Bourdon test performance. Calculation test performance tended to be affected by exposure to cold or neutral temperatures at the beginning of the test. Cold exposure undermined manual motor performance (especially when combined with fewer clothing items) while heat exposure significantly increased heart rate. Both cold exposure and higher clothing level during heat exposure increased blood pressure. Body temperature, particularly mean skin temperature, increased with higher air temperature and was significantly influenced by clothing insulation during cold exposure. These results provide novel evidence for the effects of clothing and air temperature (particularly cold) on human productivity and physiological responses in humans.
本研究评估了服装和空气温度组合对工作场所生产力和生理反应的影响。十名日本男性受试者分别暴露于六种服装（0.3 clo 和 0.9 clo）和空气温度（16°C、26°C 和 36°C）组合下，期间测量了认知表现（Bourdon 和计算测试）、手动运动表现（手指敲击测试）和生理反应（心率、血压、皮肤和口腔温度）。寒冷暴露和较低的服装水平可能会提高 Bourdon 测试表现。在测试开始时，计算测试表现可能会受到寒冷或中性温度的影响。寒冷暴露会破坏手动运动表现（尤其是与较少的服装搭配时），而热暴露会显著增加心率。寒冷暴露和热暴露时较高的服装水平都会增加血压。体温，特别是平均皮肤温度，随着空气温度的升高而升高，在寒冷暴露期间，受服装隔热的影响很大。这些结果为服装和空气温度（特别是寒冷）对人类生产力和生理反应的影响提供了新的证据。
