Blinded by the light pollution: Cities seek to restore night

A study published in Nature found global artificial nighttime light emissions rose 16% between 2014 and 2022, causing negative human health impacts including disrupted sleep cycles and elevated chronic disease risk, as well as widespread harm to nocturnal wildlife and biodiversity. Multiple European nations and cities have implemented targeted light pollution regulations and adaptive low-intensity lighting solutions, leading to measurable regional reductions in light emissions over the study period.
