According to a report on November 3 on the website of Science Daily, a preliminary analysis to be presented at the American Heart Association's Scientific Sessions in 2025 found that increased nighttime artificial light is associated with increased b

Investigators have found that artificial light at night, commonly known as night light pollution, is nearly ubiquitous in modern urban environments. This is the first study of its kind to combine brain imaging and satellite measurements to outline th

Shadi Abou-Hamad, the senior author of the study and a medical doctor with a master's degree in public health, said, "We know that environmental factors such as air and noise pollution can affect our nerves and blood vessels through stress, leading t

All participants underwent the same PET/CT examination. None of the 450 adult subjects in the study had heart disease or cancer. Abulhashim said, 'This is a routine imaging examination in our hospital. The CT part provides detailed anatomical images,

A key result of the experiment is that the stronger the light, the greater the risk.

People exposed to high-intensity artificial light at night are at higher risk of brain stress activity, vascular inflammation, and major heart disease. This information is from medical records and has been evaluated blindly by two cardiologists, whic

The higher the exposure to artificial light at night, the greater the risk of heart disease. During the 5-year and 10-year follow-up periods, for each standard deviation increase in light exposure, the risk of heart disease increased by 35% and 22%,

In addition, participants living in areas with greater social or environmental pressure, such as communities with higher traffic noise or lower income, are at a higher risk of heart disease.

"We found a nearly linear relationship between nighttime lighting and heart disease: the more nighttime light exposure, the higher the risk of heart disease. Even a moderate increase in nighttime light exposure can lead to increased brain and artery

To combat the impact of artificial light at night, he suggested that cities could reduce unnecessary outdoor lighting, shield street lamps or use motion-sensing lights. For individuals, people can reduce indoor light at night, keep their bedrooms dar
