Artificial light at night

Year: 2026

Type: article

Abstract: Exposure to ALAN disrupts the circadian system in humans and has a negative impact on the body by increasing the risk of cancer, sleep problems and metabolic disorders. Food intake during the resting phase also has an inappropriate impact on the circadian system. The individual can prevent exposure to ALAN by avoiding the use of electronic screens in the bedroom, not sleeping with the light on and avoiding eating late in the evening or at night. In general, replacing traditional LED bulbs with dynamic alternatives (with reduced blue light) is an option to reduce light pollution at night, as argued in this review.
