Sleep is a reversible state that sustains physiological and psychological processes in humans. As well established, individual-level factors, such as stress, smoking, drugs, and caffeine intake, reduce sleep duration and quality. However, studies of the effect of environmental risk factors, such as artificial light at night (ALAN) and noise, on sleep have been infrequent. Using records obtained from the 2017 Social Survey of Israel and combined with ALAN satellite data and various proxies for traffic noise, the present study aimed to determine how the combination of ALAN and traffic noise impact sleep duration and quality in urban areas. The increase of road density at the place of residence reduces average sleep duration by 4.5% (18 min.) and increases the frequency of reported sleep difficulties by 3.5%, all other factors held equal. Similarly, an increase in ALAN exposure reduces average sleep duration by ~3% (12 min) and increases the frequency of reported sleep difficulties by ~11%. The study also reveals a significant interaction between the two environmental risk factors in question, with the adverse impact of ALAN on sleep quality especially pronounced in high noise exposure areas.
睡眠是一种可恢复的状态，可维持人类的生理和心理过程。众所周知，个体水平的因素，如压力、吸烟、药物和咖啡因摄入，会减少睡眠时间和质量。然而，关于环境风险因素（如夜间人工光（ALAN）和噪声）对睡眠的影响的研究并不频繁。本研究利用 2017 年以色列社会调查获得的记录，并结合 ALAN 卫星数据和交通噪声的各种替代指标，旨在确定 ALAN 和交通噪声的组合如何影响城市地区的睡眠持续时间和质量。居住地道路密度的增加会使平均睡眠时间减少约 4.5%（约 18 分钟），并使睡眠困难的报告频率增加约 3.5%，所有其他因素保持不变。同样，ALAN 暴露的增加会使平均睡眠时间减少约 3%（约 12 分钟），并使睡眠困难的报告频率增加约 11%。该研究还揭示了两个环境风险因素之间存在显著的相互作用，ALAN 对睡眠质量的不利影响在高噪声暴露区域尤为明显。
