Sleep problems are more common with the prevalence of digital media devices. Subjective and objective research has shown evidence of negative sleep impacts of digital media usages. The underlying mechanisms involve sleep displacement, hyperarousal and effects of screen light and electromagnetic radiation. Sleep education, restriction of digital media usage and blocking blue light from screen can be promising options to alleviate the undesirable effects of digital media on sleep. More effort should be devoted to the integration of theoretical models, causality establishment between digital media and sleep, objectivization and standardization of measurements, refined classification of digital media user behaviors and local research.

Key words: digital media, sleep, sleep displacement, arousal, screen light, electromagnetic radiation
