Teens who go to bed late are more prone to academic and emotional difficulties in the long run, compared to teens who turn in early, a new study shows.
Adolescents who go to bed late during the school year are more prone to academic and emotional difficulties in the long run, compared to teens who turn in early.
Researchers analyzed longitudinal data from a nationally representative cohort of 2,700 US adolescents of whom 30 percent reported bedtimes later than 11:30 p.m. on school days and 1:30 a.m. in the summer in their middle and high school years.
By the time they graduated from high school, the school-year night owls had lower GPA scores, and were more vulnerable to emotional problems than teens with earlier bedtimes, according to the study published in the Journal of Adolescent Health.
The results present a compelling argument in favor of later middle and high school start times in the face of intense academic, social and technological pressures, researchers says.
