  There is a surging concern regarding the adverse effects of light pollution
on human well-being. This manuscript aims to emphasise the deleterious effects
of uncontrolled night-light exposure on the health and mood of individuals
residing in a highly populated elite metropolitan society compared to those
residing in remote villagesin a scattered manner. A comprehensive study has
been undertaken on the influence of unnecessary and excessive illumination of
light during late-night hours on individuals' day-to-day lives. Prolonged
exposure to unwanted intense artificial lighting disrupts the secretion of
melatonin, interferes with the circadian rhythm, and unusual sleep patterns.
Such disturbances can lead to significant health issues, including insomnia,
depression, cardiovascular diseases, as well as an increased risk of breast and
prostate cancer. Findings emphasize the need for a more holistic understanding
of how artificial light, in intensity and periodicity, affects the physical and
mental health of humans and the ecological system in entirety, specifically in
urban settings.
