背景：光是生物钟和睡眠/觉醒周期的强大同步器。盲人比没有视力问题的人有更多的睡眠障碍。然而，视觉能力强的人在明亮的自然光下暴露不足是否会患上睡眠障碍从未被研究过。这项研究试图评估在不暴露于自然光的环境中工作的受试者的睡眠和觉醒障碍的患病率。方法：采用现场对照的横断面流行病学研究方法。一个单一的运输公司的13 296名法国雇员的代表性样本参加了这项研究。在工作时间内，4635名受试者（34.9%）没有暴露于光（NLE），8661名受试者部分或完全暴露于自然光（LE）。使用主观工具评估睡眠障碍、睡眠质量和嗜睡：睡眠障碍问卷法语版（SDQFV）和埃普沃思嗜睡量表（ESS）。根据工人的时间表和光强度的客观测量（勒克斯计）估计光暴露。主要发现：在单变量分析中，NLE工作者睡眠质量差和嗜睡的投诉明显高于LE：非恢复性睡眠（36.8%对29.5%; P
Background: Light is a powerful synchronizer of the biological clock and of the sleep/wake cycle. Blind people have more sleep disturbances than people without eyesight problems. However, whether visually able people who are underexposed to bright natural light suffer from sleep wake disorders has never been examined. This study tried to assess the prevalence of sleep and wake disorders in subjects working in environments that arc not exposed to natural light. Methodology: A setting controlled cross sectional epidemiological study was carried out. A representative sample of 13 296 French employees of a single transportation company participated in the study. During working hours, 4635 subjects (34.9%) experienced no light exposure (NLE) and 8661 were partially or completely exposed (LE) to natural light. Sleep disorders, sleep quality, and sleepiness were assessed using subjective tools: the Sleep Disorders Questionnaire French version (SDQFV) and the Epworth Sleepiness Scale (ESS). Light exposure was estimated on workers' schedules and by Objective measurements of light intensity (lux meter). Principal findings: On a univariate analysis, complaints of poor sleep and sleepiness were significantly higher in NLE workers compared to LE: nonrestorative sleep (36.8% vs. 29.5%; P
