Impact of Light Pollution on Circadian Rhythms: Unveiling a Hidden Disruptor
In an era where artificial light dominates our nights, the Western Slope Dark Sky Coalition highlights the detrimental effects of light pollution on human health and circadian rhythms. Our body’s internal clock relies on natural light cues for regulating sleep, metabolism, and mental well-being, but excessive exposure to bright, artificial light at night disrupts these processes. This “light contamination” can suppress melatonin production, leading to a host of health issues, including sleep disorders, increased stress, and a higher risk of conditions like obesity and depression. To combat this, individuals are encouraged to reduce their evening light exposure and communities can advocate for smarter lighting solutions. Addressing light pollution is not only essential for reclaiming our night skies but also for safeguarding our overall health.
