Digital distractions, and a more classical one, talking on the phone, are linked to shorter sleeping time and greater daytime sleepiness for teens, Canadian researchers say.

“Today’s adolescents sleep much less than previous generations, their sleep quality is poorer and they report more daytime sleepiness, all of which have health and social consequences,” said Jennifer O’Loughlin, author of the paper in the journal Sleep Health and researcher at the University of Montreal.

At the same time, electronic media are becoming a larger part of teens’ lives and are often used before bed.

To explore the link between time spent using electronics such as video games, TVs and phones and the amount of sleep teens are getting, the study team analysed data from a study of high school students.

More than 1 200 students between 14 and 16 years old completed questionnaires between 2008 and 2009 reporting on how often they used electronics, including watching TV, as well as how often they did other sedentary activities like reading, doing homework or talking on the phone.

Researchers found that kids who used computers and video games for more than two hours per day, slept 17 and 11 minutes less than those who used screens for less time.

One in three teens used computers for more than two hours per day and they were more than twice as likely as the others to sleep less than eight hours a night.

Teens who talked on the phone for at least two hours daily were also three times more likely than those who didn’t to fall short of eight hours of sleep. – Reuters Health
