A recent study conducted in China involving over 28,000 adults has found a potential link between exposure to outdoor artificial light at night and an increased risk of stroke. The research, led by experts from Zhejiang University School of Medicine, used satellite images to measure light pollution and correlated it with cases of stroke among participants over a six-year period. The study revealed that individuals with the highest levels of outdoor artificial light exposure had a 43% higher risk of developing cerebrovascular disease.
People continuously exposed to bright, artificial light at night may be at increased risk of developing conditions that affect blood flow to the brain and having a stroke, according to research published today in Stroke, the peer-reviewed scientific journal of the American Stroke Association, a division of the American Heart Association.
