Nighttime light exposure linked to higher heart attack risk, study finds

Scientists from Australia, England and the United States found that people exposed to more artificial light at night showed elevated levels of brain stress, blood vessel inflammation and an increased risk of major cardiovascular issues. The large-scale study tracked nearly 90,000 adults’ nighttime light exposure and monitored their health outcomes over eight years. Researchers discovered that participants living in the brightest nighttime environments faced a 50% higher chance of having a heart attack compared to those in darker settings.
