Mitigating Light Pollution for Enhanced Public Health and Safety

In Philadelphia, the pervasive artificial light that illuminates the city at night has become a normalized aspect of urban life, obscuring the night sky and reducing visibility of stars. Thousands of streetlights, along with the constant glow from buildings and billboards, contribute to this phenomenon, which many residents accept as inevitable. However, the adverse effects of light pollution extend well beyond diminished stargazing; research indicates it disrupts sleep patterns, alters circadian rhythms, and suppresses melatonin production, leading to increased risks of health issues such as depression, insomnia, obesity, diabetes, heart disease, and cancer. This growing concern highlights light pollution as a significant public health challenge, necessitating greater awareness and action to address its impacts on well-being.
