Teens spend more than a quarter of their time at school on phones, new study finds

New study from Seattle Children's Hospital shows that more than a quarter of children's time spent on their smartphones occurs in school.

The study's findings come just several days after the state of Colorado introduced House Bill 1135, which would require school districts in the state to adopt policies that limit the use of cellphones by students during school hours. If passed, Colorado would join 19 other states that have adopted some type of cellphone restrictions for students, according to Democratic state Rep. Meghan Lukens. 

"I'm not a big fan of government controlling people's lives, but in this context, I'm all for it," psychotherapist Thomas Kersting told Fox News Digital. Kersting is a former school counselor who has lectured for 16 years about the adolescent impact of increased screen time. He wrote a bestselling book called "Disconnected," which posited that increased screen time for kids is re-wiring their brains.
