Touchscreens May Be Hurting Your Kids' Sleep

Touch screen devices could be keeping kids from getting as much sleep as they should be getting, recent research suggests.

In a  survey involving 715 families based in the U.K., 75 percent of toddlers use a touch screen device daily, and it could have a direct impact on how long it takes them to get them to sleep and how frequently they wake up at night.  The survey was conducted online between June 2015 and March 2016 and published in the journal Nature in mid-April.

As part of the survey, parents reported on how long their kids sleep during the day and night, how long it takes them to fall asleep, and how often they wake up at night. Every hour of touchscreen use seems to have reduced total daily sleep by 15.6 minutes, with kids getting 26.4 minutes less sleep at night and 10.8 minutes more during the day, on average, the survey found. There was no clear association between hours using touch screens and the number of times a kid woke up at night, however.

Researchers have discouraged keeping touch screen devices out of childrens' rooms, because they can seek them out when they wake up at night, keeping them awake, and the blue light emanating from the screens can suppress their levels of melatonin, a naturally-occuring chemical that promotes sleep.

A look at several studies on kids' sleep shows that screen time is consistently linked with with shorter total sleep time and delayed bedtime, researchers said. Poor sleep in general can impact a kid's overall development, but there's limited research into the problem, they admitted.

Until last year, the American Association of Pediatrics discouraged screen time at all for kids younger than 2, but it took back that advice late last year, saying children younger than 18 months can benefit from educational content, but shouldn't have more than an hour's worth of screen time, and parents should limit the amount of time that older kids spend in from of a screen as well.

The National Sleep Foundation has also said that adults are also impacting how long and how well they sleep by keeping their phones in or close to their beds as well.
