Students Aren't Getting Enough Sleep—School Starts Too Early

A new report from the American Academy of Pediatrics says delaying the day may help teens get more rest.

As the lazy days of summer give way to the painful reality of pre-dawn alarms, many kids are beginning their descent into chronic school-year sleep deprivation. The median school start time in this country is 8 a.m. But this fall, some schools, including a handful of elementary schools in New York City, will ring their first bell up to 40 minutes earlier than they did last year in order to accommodate curricular demands.

These early school start times result in sleepy kids and frustrated parents. But, as of Monday, those kids and parents have the formidable weight of the American Academy of Pediatrics on their side. The organization released a new policy statement saying that “insufficient sleep in adolescents [is] an important public health issue that significantly affects the health and safety, as well as the academic success, of our nation’s middle and high school students.”

“The empirical evidence [of] the negative repercussions of chronic sleep loss on health, safety and performance in adolescents … has been steadily mounting for over the past decade,” wrote Judith Owens, a pediatrician and the lead author of the report, in an email. “For example, an important recent study published this spring by Dr. Kyla Wahlstrom documented the positive effects of school start time delay in over 9000 students from eight high schools in three states, including improved grades and standardized test scores and up to a 65 to 70 percent reduction in teen car accidents.”

According to the Academy, the solution is to delay school start times. “In most districts, middle and high-schools should aim for a starting time of no earlier than 8:30 a.m. However, individual school districts also need to take average commuting times and other exigencies into account in setting a start time that allows for adequate sleep opportunity for students,” it said in a statement.

The organization also published a report that summarizes the current research on teen sleep trends, health consequences of chronic sleep deficits, factors that contribute to lost sleep, and ways to promote healthy rest in adolescents. The main take-away is that American teens are not getting enough sleep, which damages their mental and physical health, education, and even ability to drive safely.

According to the National Sleep Foundation, teenagers need at least nine and a half hours of sleep every night. However, the National Sleep Foundation’s 2014 Sleep in America Poll reports that less than half of American children get at least nine hours of sleep each night, and 58 percent of 15- to 17-year-olds regularly sleep fewer than seven hours each night. Since poll respondents tend to overestimate the number of hours they sleep, actual nightly sleep totals are likely lower than these self-reported averages.

Chronic sleep loss contributes to higher rates of depression, suicidal ideation, and obesity. Long-term deprivation has also been shown to be a factor in lower test scores, decreased attention span, tardiness, concentration, and overall academic achievement.
