A new study found that electronics in the bedroom are to blame for groggy kids.
The National Sleep Foundation has released it's annual "Sleep in America" poll. The poll tracks several thousand parents and kids. According to the study, the biggest sleep deterrents for kids are electronics in the bedroom.
"Noise will disturb your sleep especially if it's left on," Kristen Knutson, a Ph.D from National Sleep Foundation, told NBC.
Numbers from the poll show that roughly three-quarters of elementary age children have an electronic gadget that glows in a dark room. The numbers spike even higher for teens. The study shows 90-percent of teens keep a glowing gadget in the bedroom.
Experts say that parents need to crack down on devices in order to allow children to get a good night's sleep.
