Abstract
Light pollution is a rising global concern which impacts not only ecology but has a wide range of deleterious effect on human health as well. Artificial light at night (ALAN) has been linked to increased risk of cancers including shift workers at night. Apart from cancer, ALAN has been the cause of disrupted circadian rhythm, disturbances in sleep pattern, obesity, stress, alterations in the rhythmicity of gut microbiota and free radical damage. Melatonin, a wonder molecule dubbed as the hormone of darkness, appears to be involved in a plethora of physiological processes and abnormalities including control of sleep, circadian rhythms, retinal physiology, seasonal reproductive cycles, cancer development and growth, immune activity, antioxidation and free radical scavenging. Potential detrimental effects of artificial light are not known to all, hidden perils of light are yet to be brought in full public knowledge so that nighttime light can be dealt with effectively.
