Recent research highlights the profound impact of artificial light at night (ALAN) on human health and the environment. For centuries, humans have evolved alongside natural day-night cycles, with biological functions synchronized to these rhythms. However, the rise of ALAN, especially during the 20th century, disrupts this delicate balance by altering the natural darkness crucial for melatonin production and other restorative hormones. This disruption has been linked to various health issues, including increased stress, anxiety, and cognitive decline, while also straining public healthcare systems. Beyond human well-being, light pollution poses risks to wildlife, affecting migration patterns and predator-prey dynamics. Experts urge society to reconsider its reliance on bright, blue-spectrum outdoor lighting in favor of non-white alternatives that protect both health and the environment, emphasizing the need for regulation and awareness around this often-overlooked issue. The conversation around light pollution is essential, as its effects extend beyond mere visibility to encompass cultural, ecological, and safety considerations.
