Abstract

Objectives: Technology use among adolescents is increasing, however, there is a lack of empirical evidence showing how this impacts adolescents’ sleep. It is possible that bright screen light, emitted by electronic devices before bed, increases alertness and
inhibits sleep. The present study explored whether this shortwavelength light (i.e., blue) results in pre-bed alertness, or additionally, whether later chronotypes are hypersensitive to evening light.
