Artificial light is light produced by human-made sources, such as electric lamps, LEDs, and screens, rather than by natural sources like the sun. It illuminates homes, streets, workplaces, and devices, and has become integral to modern life. Beyond its practical role, artificial light is an important subject of scientific study because of its effects on biological systems. Exposure to artificial light, particularly at night, can influence the body's internal clock and circadian rhythms, affecting processes such as sleep, hormone release, and behavior in humans, animals, and plants. Research in this subject area examines how light, including artificial sources, interacts with biological and environmental processes. Studies have explored the genetic and cultural factors underlying circadian sleep timing and delayed sleep phase, the influence of natural light cycles on the activity of insect species, the effects of ultraviolet light on plant physiology, and the role of light conditions in cultivating photosynthetic algae. This page gathers peer-reviewed, open-access research relevant to artificial light and its effects on circadian rhythms, sleep, and biological and environmental systems.
