Europe’s fading night sky becomes a public-health issue
A long-form piece argues that almost all of Europe now lives under light-polluted skies that erase real darkness, a change scientists are increasingly treating as a public-health issue because nighttime artificial light is linked to sleep disturbances and mental-health patterns. Citing a 2016 atlas showing 99% of people in the U.S. and Europe under skies too bright to see real darkness, plus research from the National Institute of Mental Health and others, the article contends that excessive lighting shifts physiology and mood. It blends personal experience—standing under a pristine sky in Bronchales—with scientific context to emphasize that darkness is a measurable environmental factor, not just an astronomy concern, and calls for urban lighting that preserves stars while maintaining safety and function.
