A study finds that taking away a teen’s phone or tablet at night does not make them sleep better or longer nor does it mean they will perform better in sports the following day, reports The Australian.

“We thought they would go to sleep earlier … because that’s what middle aged and older people do in similar studies,” he said.

“However, these guys were so young — between 16 and 19 — and they did go to bed earlier but they didn’t fall asleep and we think that’s because teens have that locked-in owl-like sleep ­behaviour … it’s like asking a 30-year-old to go to sleep at 5pm. They just can’t do it.”
