More sleep leads to better academic success, says the AAP
September 30, 2014

In a technical report issued by the American Academy of Pediatrics (AAP) last month, chronic sleep loss among middle and high school students was cited as a “serious threat to academic success.” There are many contributing factors to a generation of sleepyheads—among them increased caffeine consumption and the use of electronic devices, whose low-intensity light can disrupt circadian rhythms and suppress melatonin production. The AAP study outlines that one key contributor could be best manipulated to help alleviate this problem: later school start times.


Beside extending sleep duration, this delay would have significant positive effects on self-reported sleepiness and academic achievement, says the Academy. But according to a U.S. Department of Education 2011-12 survey, of the 18,000 high schools in America, less than 15% start at 8:30 a.m. or later, and more than 40% start before 8 a.m.


Dr. Bob Weintraub, headmaster of Brookline High School in Massachusetts from 1992 to 2011 and now professor of educational leadership at Boston University, says that during his tenure the high school moved start times for most students to 8:30 a.m. But he also points out that these shifts raise concerns like how to have maximum participation in after-school activities like athletics, drama, and music when later start times means later end times (which means in the dark during winter months in the Northeast).


Despite these challenges, the AAP argues that communities nationwide have been creative in coming up with solutions to this challenge, including providing free periods and study halls at the end of the day, exempting student athletes from PE, and installing lights for athletic fields.


In sum, the Academy “strongly supports the efforts of school districts to optimize sleep in students and urges high schools and middle schools to aim for start times that allow students the opportunity to achieve optimal levels of sleep and to improve physical and mental health, safety, academic performance, and quality of life.”
