The glow emitted from electronic devices such as computers, mobile phones, lamps, streetlights, and other sources of night-time lighting disrupts the body’s natural rhythms, which have evolved to synchronize with the sun’s light and darkness. According to research by neuroscientist Dr. Randy J. Nelson, who has dedicated the past decade to uncovering the risks posed by exposure to artificial light at night, night light not only reduces sleep quality but also exposure to light at inappropriate times may suppress natural immune responses, trigger neurological inflammations, and affect metabolic processes, disrupting the biological clock and metabolism.

Dr. Nelson suggests that reducing screen time in the evening, using warm lighting colors after sunset, and maintaining regular sleep schedules can significantly impact people’s health. Perhaps most importantly, Dr. Nelson’s research shows direct effects of night light on mood stability, which has implications for understanding depression and anxiety disorders.
