Students say their New York school's cellphone ban helped improve their mental health

Newburgh, New York — At Newburgh Free Academy in New York, cell phones are locked away for the entire school day, including lunch.

Students like Tyson Hill and Monique May say it is a relief after constantly being on their phones during the COVID-19 lockdown, when screen time among adolescents more than doubled, according to a study last year in the Journal of the American Medical Association Pediatrics.

"I blame my darkest moments because of my phone," Tyson told CBS News.
