Artificial light harms health by disrupting sleep cycles

Light pollution, caused by excessive artificial light, is increasingly linked to significant health problems, particularly sleep disruption and its associated consequences. Exposure to artificial light at night suppresses melatonin production, disrupting the body's natural sleep-wake cycle and potentially leading to fatigue, mood disorders, and weakened immune function. This disruption can also contribute to metabolic issues and cardiovascular problems. Studies suggest that light pollution may also increase the risk of certain cancers and eye problems, highlighting the need for awareness and mitigation strategies to protect public health.
