Abstract and Keywords

Technological devices have become more affordable, multifunctional, and portable over recent years. Not only have the number of devices increased in families’ households, but also increasingly more evidence documents that children and adolescents keep these devices in their bedrooms. On a related note, the percentage of youth who use technology before bed is remarkably high, and emerging evidence shows technology is now being used during the night. This chapter reviews the effects of various technological devices (TVs, computers/Internet, video games, cell phones, music players) on the sleep of children and adolescents. Possible mechanisms explaining these effects (including displacing bedtime, arousal, light and electromagnetic transmission, and nighttime sleep disruption) are discussed, as well as potential modifying factors of age, gender, socioeconomic status, and parental involvement. Directions for future research and recommendations for families and health professionals are provided in order to continue to improve the sleep hygiene of our youth.

Keywords: children, adolescents, technology, media, sleep
