Artificial light is keeping reef fish awake in the Gulf of Aqaba; they sleep less, get more aggressive, and carry signs of brain stress, a study finds

Coastal light pollution is disrupting the sleep patterns of sea animals, particularly coral reef fish. A new study reveals that even low levels of artificial light at night cause blue-green damselfish to lose sleep, become aggressive, and experience cellular stress in their brains. This disruption threatens the delicate balance of reef ecosystems, highlighting the urgent need for mitigation measures like reducing unnecessary lighting.
