“Catching up” on sleep doesn’t work, reports the New York Times.

Within a week of my grandsons’ first year in high school, getting enough sleep had already become an issue.

Their concerned mother questioned whether lights out at midnight or 1 a.m. and awakening at 7 or 7:30 a.m. to get to school on time provided enough sleep for 14-year-olds to navigate a demanding school day.

The boys, of course, said “yes,” especially since they could “catch up” by sleeping late on weekends. But the professional literature on the sleep needs of adolescents says otherwise.
