Study reveals: Artificial light is keeping reef fish awake
Bar-Ilan University study finds that coastal light pollution disrupts sleep and is associated with increased markers of DNA damage in the brains of reef fish
Assessment
A new study from Bar-Ilan University links artificial coastal light to disrupted sleep and DNA damage markers in reef fish brains. This suggests light pollution may harm marine life at a cellular level, not just behaviorally. The findings raise questions about how coastal development and nighttime lighting affect ecosystem health beyond immediate visibility.
