The presence of artificial light at night has emerged as an anthropogenic stressor in recent years. Various sources of light pollution have been shown to affect circadian physiology with serious consequences for metabolic pathways, possibly disrupting pineal melatonin production with multiple adverse health effects. The suppression of melatonin at night may also affect human mental health and contribute to the development or exacerbation of psychiatric disorders in vulnerable individuals. Due to the high burden of circadian disruption in affective disorders, it has been hypothesized that light pollution impacts mental health, mainly affecting mood regulation. Hence, the aim of this review was to critically summarize the evidence on the effects of light pollution on mood symptoms, with a particular focus on the role of circadian rhythms in mediating this relationship. We conducted a narrative review of the literature in the PubMed, Scopus, and Web of Science datasets. After the screening process, eighteen papers were eligible for inclusion. The results clearly indicate a link between light pollution and the development of affective symptoms, with a central role of sleep disturbances in the emergence of mood alterations. Risk perception also represents a crucial topic, possibly modulating the development of affective symptoms in response to light pollution. The results of this review should encourage a multidisciplinary approach to the design of healthier environments, including lighting conditions among the key determinants of human mental health.
近年来，夜间人造光已成为一种人为应激源。各种光污染源已被证明会影响昼夜生理节律，对代谢途径产生严重影响，可能会扰乱松果体褪黑素的分泌，从而产生多种不良健康影响。夜间褪黑素分泌受抑制还可能影响人类心理健康，并促使易感个体发生精神障碍或使其病情加重。由于情感障碍中昼夜节律紊乱的负担较重，因此有人推测光污染会影响心理健康，主要影响情绪调节。因此，本综述的目的是批判性地总结关于光污染对情绪症状影响的证据，特别关注昼夜节律在介导这种关系中的作用。我们对PubMed、Scopus和Web of Science数据集中的文献进行了叙述性综述。经过筛选过程，有18篇论文符合纳入标准。结果清楚地表明光污染与情感症状的发生之间存在联系，睡眠障碍在情绪改变的出现中起核心作用。风险认知也是一个关键话题，可能会调节对光污染的情感症状的发展。本综述的结果应促使采用多学科方法来设计更健康的环境，将照明条件作为人类心理健康的关键决定因素之一。
