Objective and Study Design: This was a cross-sectional study purposed to observe the effects of led bulbs and artificial lights on human health and its physiological considerations on sleep. Our study addressed two goals. Our first goal was to determine the extent to which light pollution was perceived as a problem by the people. Our second goal was to recommend applicable lighting ordinances for reducing light pollution. Material and Methods: This study was conducted at All India Institute of Medical Sciences hospital, Bhopal and Narayana medical college, Nellore during the period between May 2014 and August 2015. Three hundred human volunteers, 123 female and 177 male, ages of 18 and 55 were studied in a two-part experiment, which included one Sleep questionnaire regarding light pollution to study each individuals normal body conditions, and one Assay of melatonin in saliva. Results: The results showed that many participants have a long history of sleeping problems. They usually take at least an hour to fall asleep and tend to wake up frequently throughout the night and feel poorly rested in the morning. The salivary melatonin levels also declined at night due to progressive exposure to artificial light. Conclusion: Through our research, we have obtained data that strongly suggest that light pollution is adversely affecting public health, causing them to experience sleep loss, visual fatigue, weariness, anxiety, and depression.
