Late Sleep, Worse Grades


By Staff Reports

(Victor Valley)– From the U.S. Department of Health and Human Services, I’m Ira Dreyfuss with HHS HealthBeat.

Not getting enough sleep is bad for everybody, and a study indicates teenagers can see it in their grades all the way through college. At the University of California, Berkeley, Lauren Asarnow found that in national survey data on 2,700 teens from 13 to 18:

“Going to bed after 11:30 p.m. during the school year, particularly in younger adolescents, predicted worse cumulative GPA at high school graduation, in the college years, and beyond.”

She says teens who went to bed late also were more likely to feel sad or blue – and this, too, was a pattern that continued into college and beyond.

But sleep habits can be changed, and Asarnow says the change should be thorough – weekends, too.

The study in the Journal of Adolescent Health was supported by the National Institutes of Health.
