Increasing urbanisation and the installation of new streetlights, security floodlights and outdoor ornamental lighting all contribute to growing light pollution. This light floods directly into the eyes of animals that are active at night and also into the skies. There a proportion of it...

Li-Wei Hung, Sharolyn J. Anderson, Ashley Pipkin, Kurt Fristrup, Changes in night sky brightness after a countywide LED retrofit, Journal of Environmental Management, Volume 292, 2021, 112776, ISSN 0301-4797,https://doi.org/10.1016/j.jenvman.2021.112776.(https://www.sciencedirect.com/science/article/pii/S0301479721008380) Abstract The US National Park Service (NPS) Night Skies Program measured changes in sky brightness resulting from a countywide lighting retrofit project. The retrofit took place in Chelan County, a gateway...

Light pollution, sleep deprivation, and infant health at birth

February 5, 2021
Argys, LM, Averett, SL, Yang, M. Light pollution, sleep deprivation, and infant health at birth. South Econ J. 2021; 87: 849– 888. https://doi.org/10.1002/soej.12477 Abstract We conduct the first study to examine the fetal health impact of light pollution based on a direct measure of skyglow, an important aspect of light pollution. Using an empirical regularity discovered in physics (called Walker’s law) as an instrumental...
