Increase in Artificial Light Pollution Raises Health Concerns and Threatens Well-being in Cities<\/p>\n

The future looks brighter… but due to the increase in artificial light pollution. Our cities and towns are spreading with a level of illumination never seen before, but these lights may be flooding into our lives and affecting our health.<\/p>\n

Recent journalistic insights have linked exposure to artificial light at night with Alzheimer’s disease, capturing the attention of neuroscientist and presenter Julia Ravey. While this field of research is still in its early stages, Julia questioned how much progress has been made regarding the human health implications of this tangibly indirect light pollution.<\/p>\n

For thousands of years, the use of light\u2014from torches to gas lamps to LEDs\u2014has had a significant impact on achieving rapid evolutionary progress. Dr. Nick Dunn, a Professor of Urban Design at Lancaster University, explores this ancient historical relationship between humans and artificial light, and how our visceral feelings about darkness may play a role in exacerbating the over-illumination of our cities. Professor Russell Foster, a Professor of Circadian Neuroscience at the University of Oxford, explains how this nighttime artificial light has allowed us to bypass our biological schedules\u2014and what the resulting health consequences are.<\/p>\n

But the question remains: does living in our non-stop bright urban environments mean our health is deteriorating? Preliminary studies are suggesting initial answers.<\/p>\n

As scientific research continues to advance, nighttime light levels continue to increase. However, some hope to challenge this trend. In Sedbergh, Julia met with Janie and Jack, who showed her modern “dark-sky friendly” streetlights, which help save on bills and reduce harmful skyglow. At York St John University, she joined a campus tour involving researchers and university administration in a project to enhance the university’s lighting, which could become a model for York to become the first “dark-sky friendly” city in the UK. However, changing the lights in our cities must be balanced with citizens’ perceptions of safety.<\/p>\n

She discusses her research on making urban parks safer for women and girls, and the role of lighting in making these areas more usable.<\/p>\n
