摘要

轮班工作会导致无数负面的健康和安全后果。照明对策可以通过光的生理效应(如警觉、昼夜节律调整)使轮班工人受益,而短波长光最能引起这些反应;然而,有限的研究表明,警觉可能并不需要短波长光。我们开发了类似外观的灯箱(相关色温:3000-3375 K;光照度:1.5-2.5°C):3000-3375 K;光照度:260-296 勒克斯),并在一个高度安全的值班楼层实施。在这项参与者内部交叉研究中,对上 12 小时夜班的人员(n = 47)进行了这两种新型照明干预措施的有效性和可行性评估。在每种干预条件下,灯箱都布置在值班楼层的前方,并照亮整个轮班;班后和睡前佩戴蓝光阻隔眼镜;睡觉时使用睡眠面罩。基线和干预条件之间的比较包括警觉性、睡眠、情绪、生活质量(QOL)和执行措施。与基线相比,SW- 条件下的当班警觉性(卡罗林斯卡嗜睡量表)有所提高,而 SW+ 条件下的变化则较为有限。在 SW+ 下,情绪和睡眠都有所改善。精神运动警觉任务的表现并不因条件而异;但是,在 SW- 条件下,感知表现和 QOL 更高,报告的咖啡因消耗量和睡眠开始潜伏期更低。两种干预措施的满意度和舒适度都很高,报告的症状和负面情绪也较少。在这种独特的工作环境中添加光谱工程灯,既能改善睡眠、警觉性和情绪,又不会影响视觉舒适度和满意度。本文是 "睡眠与昼夜节律 "的一部分:职业环境中的疲劳管理》文集的一部分。

Hybrid effectiveness-implementation study of two novel spectrally engineered lighting interventions for shiftworkers on a high-security watchfloor.

Shiftwork leads to myriad negative health and safety outcomes. Lighting countermeasures can benefit shiftworkers via physiological effects of light (e.g. alerting, circadian adjustment), and short-wavelength light is the most potent for eliciting those responses; however, limited work indicates it may not be required for alerting. We developed similar-appearing light boxes (correlated color temperature: 3000-3375 K; photopic illuminance: 260-296 lux), enriched (SW+, melanopic EDI: 294 lux) or attenuated (SW-, melanopic EDI: 103 lux) in short-wavelength energy, and implemented them on a high-security watchfloor. Efficacy and feasibility of these two novel lighting interventions were assessed in personnel working 12-hour night shifts (n = 47) in this within-participants, crossover study. For each intervention condition, light boxes were arranged across the front of the watchfloor and illuminated the entire shift; blue-blocking glasses were worn post-shift and before sleep; and sleep masks were used while sleeping. Comparisons between baseline and intervention conditions included alertness, sleep, mood, quality of life (QOL), and implementation measures. On-shift alertness (Karolinska Sleepiness Scale) increased in SW- compared to baseline, while changes in SW+ were more limited. Under SW+, both mood and sleep improved. Psychomotor vigilance task performance did not vary by condition; however, perceived performance and QOL were higher, and reported caffeine consumption and sleep onset latency were lower, under SW-. For both interventions, satisfaction and comfort were high, and fewer symptoms and negative feelings were reported. The addition of spectrally engineered lights to this unique work environment improved sleep, alertness, and mood without compromising visual comfort and satisfaction. This paper is part of the Sleep and Circadian Rhythms: Management of Fatigue in Occupational Settings Collection.
