工作场所照明在决定员工的生产力和幸福感方面至关重要。此外，光对生物节律产生非视觉效应。在这项研究中，我们调查了不同的照明条件（500-1800勒克斯，6500 K; 500勒克斯，4000 K）的影响，硫酸氧褪黑激素（aMT 6-S）和主观情绪在实验办公室住宿。在两种光下，尿aMT 6-s浓度在实验的所有天数均显著降低。在第3天，在可变光照条件下，在05：00 p.m.和09：00 a.m.采集的样本中aMT 6-s浓度之间的差异显著更高。情绪评级清单的分析揭示了可变光相对于“活动”的维度的益处，而“失活”和“疲劳”在第1天在常规光下增加。在连续两天比较变量与常规照明时，“活性”、“浓度”和“失活”的变化方向相反。总之，可变光在主观情绪方面在室内办公室住宿中发挥了潜在的优势，尽管与常规光相比没有发现aMT 6-s的轮廓的明确差异。(c)2007爱思唯尔有限公司保留所有权利。
Workplace illumination is of paramount importance in determining the employee's productivity and well-being. Moreover, light exerts non-visual effects with respect to biological rhythms. In this study, we investigated the impact of different lighting conditions (500-1800 lx, 6500 K; 500 lx, 4000 K) on sulphatoxymelatonin (aMT6-s) and subjective mood in an experimental office accommodation. Urinary aMT6-s concentrations were significantly decreased at all days of the experiment in both lights. On day 3, differences between aMT6-s concentrations in specimen collected at 05:00 p.m. and at 09:00 a.m. were significantly higher under variable lighting conditions. Analyses of a mood rating inventory revealed a benefit of variable light with respect to the dimensions of "Activity", while "Deactivation" and "Fatigue" were increased in regular light on day 1. "Activity", "Concentration", and "Deactivation" changed in opposite directions when comparing variable with regular illumination on two consecutive days. In conclusion, variable light exerts a potential advantage in indoor office accommodations with respect to subjective mood, although no unequivocal differences in the profile of aMT6-s were found as compared to regular light.
