We know from previous research reported on happychild that use of technology devices can negatively impact the sleep of teenagers. This new research from Finland studied an even younger population of school-aged children and concluded that computer use, television viewing, and the presence of media in children’s bedrooms may reduce the amount of time children are sleeping, and delay bedtimes. And they found gender differences–among boys, having a television and a computer in the bedroom predicted poorer sleep habits and irregularity of sleep habits.
