Light pollution is one of the fastest-growing pollutants of the environment and considering the amount and diversity of negative consequences, it is a highly interdisciplinary subject. So far, most of the research about the negative influence of light pollution on human health was based on the disruption of the circadian clock, sleep deprivation, and other physical diseases. Together with artificial lighting, the rapid development of information and communication technology significantly contributed to the increased lighting levels in the indoor environment and at the same time influenced the perception of natural darkness as something unnatural and undesired. On the other hand, the same technologies can be a useful asset in the popularization of astronomy-related activities, thus promoting the necessity for dark skies preservation. This paper aims to emphasize the importance of dark skies and appropriate usage of ICTs in the nighttime hours for our psychological health and well-being in general and at the same time to propose astronomy tourism as a part of the sustainable tourism offer as a tool for fighting light pollution.

阴暗的天空和黑色的屏幕是天文旅游和总体福祉的前提

光污染是环境中增长最快的污染物之一，考虑到负面后果的数量和多样性，它是一门高度交叉的学科。到目前为止，关于光污染对人类健康的负面影响的大多数研究都基于昼夜节律的破坏，睡眠不足和其他身体疾病。与人工照明一起，信息和通信技术的飞速发展极大地促进了室内环境中照明水平的提高，同时也影响了人们对自然黑暗的感知，这是不自然和不希望的。另一方面，在推广与天文学有关的活动中，相同的技术可能是有用的资产，从而促进了保护黑暗天空的必要性。
