Global Night Sky Brightens as Artificial Light Expands by 16%

A Nature study using satellite imagery finds artificial nighttime lights increased worldwide by about 16% from 2014 to 2022, with the United States having the highest total luminosity in 2022 and regional variations driven by conflict and disasters (notably Europe dimming during the Russia–Ukraine energy crisis). The rise in light pollution affects wildlife by disrupting sleep, navigation, and feeding, and can disrupt human circadian rhythms; the issue is reversible and individual actions—such as dimming outdoor lighting and using shields—can help, with tools like the Light Pollution Map and DarkSky resources available for guidance.

"Nighttime Light Exposure Linked to Increased Stroke Risk"

A study in China found a link between increased exposure to artificial outdoor light at night and a greater risk of stroke, as well as a connection between air pollution and stroke risk. The study suggests that excessive artificial light at night may disrupt the body's internal clock, leading to health issues, and advises people, especially those in urban areas, to reduce their exposure to outdoor artificial light to protect themselves from potential harmful impacts.
