"Outdoor Nighttime Light Exposure Linked to Increased Stroke Risk"
A new study suggests that high levels of exposure to bright outdoor lights at night are linked to a 43% increased risk of diseases affecting the blood vessels of the brain, including stroke. The research, based on data from over 28,300 adults in China, found that continuous exposure to bright light at night can suppress the production of melatonin, impairing sleep and potentially contributing to stroke risk. Additionally, the study also revealed increased stroke risk associated with air pollution, with particulate pollution and nitrogen oxide emissions from traffic and industrial power plants being identified as contributing factors. The findings highlight the need for policies and prevention strategies to reduce the burden of disease from environmental factors such as light and air pollution, particularly for those living in densely populated and polluted areas.
