Teen Night Owls May Run Into Problems

Teen Night Owls May Run Into Problems New research suggests that teenage night owls are more likely to develop academic and emotional difficulties as compared to their earlier-to-bed counterparts.

Researchers analyzed longitudinal data from a nationally representative cohort of 2,700 U.S. adolescents. Thirty percent of the teens 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.

Researchers found that 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.

The study is published online in the Journal of Adolescent Health.

Researchers believe the findings reflect intense academic, social and technological pressures and demonstrate the need for later middle and high school start times.

“Academic pressures, busy after-school schedules, and the desire to finally have free time at the end of the day to connect with friends on the phone or online make this problem even more challenging,” said Lauren Asarnow, doctoral student and lead author of the study.

On a positive note, she said the findings underscore how a healthy sleep cycle promotes the academic and emotional success of adolescents.

“The good news is that sleep behavior is highly modifiable with the right support,” said Asarnow, citing University of California – Berkeley’s Teen Sleep Study, a treatment program designed to reset the biological clocks of adolescents who have trouble going to sleep and waking up.

This latest study used data from the National Longitudinal Study of Adolescent Health, which has tracked the influences and behaviors of adolescents since 1994.

Focusing on three time periods — the onset of puberty, a year later and young adulthood — the researchers compared how the sleep habits of 2,700 teenagers aged 13-18 impacted their academic, social and emotional development.

They looked at participants’ school transcripts and other education and health data.

While going to bed late in the summer did not appear to impact their academic achievement, including grades, researchers did find a correlation between later summer bedtimes and emotional problems in young adulthood.

Surveys show that many teenagers do not get the recommended nine hours sleep a night, and report having trouble staying awake at school.

The human circadian rhythm, which regulates physiological and metabolic functions, typically shifts to a later sleep cycle at the onset of puberty.

The scientists theorize that an “evening circadian preference” in adolescence is a confluence of biological factors, as well as parental monitoring, academic and social pressures and the use of electronic gadgetry.

For example, bright lights associated with laptops, smartphones and other electronic devices have been found to suppress melatonin, a hormone that helps regulate the sleep cycle.

The Teen Sleep Study uses dim lighting and limits technology before bedtime, among other interventions, to help reverse this night-owl tendency.

‘This very important study adds to the already clear evidence that youth who are night owls are at greater risk for adverse outcomes,” said UC Berkeley psychologist Dr. Allison Harvey, senior author of the paper.

“Helping teens go to bed earlier may be an important pathway for reducing risk. This will not be an easy process. But here at Berkeley, our sleep coaches draw from the science of motivation, habit formation and sleep to help teens achieve earlier bedtimes.”
