The vast majority of public schools in the U.S. start earlier than 8:30 a.m. Like most American students, I took this as a given, albeit begrudgingly — we all struggled to get up and get focused for school, and it only got harder with each passing year. Naturally, many people chalk this up to the laziness and entitlement of adolescence. But mounting scientific research is finding that getting up really early, and being thrown into a cognitively-intensive bloc schedule, is bad for both the health and education of youth. Various leading public health authorities are urging an end to this practice.
For the first time, the federal Centers for Disease Control and Prevention is urging education policymakers to start middle- and high-school classes later in the morning. The idea is to improve the odds of adolescents getting sufficient sleep so they can thrive both physically and academically.
The CDC’s recommendations come a year after the American Academy of Pediatrics urged schools to adjust start times so more kids would get the recommended 8.5 to 9.5 hours of nightly rest. Both the CDC and the pediatricians’ group cited significant risks that come with lack of sleep, including higher rates of obesity and depression and motor-vehicle accidents among teens as well as an overall lower quality of life.
“Getting enough sleep is important for students’ health, safety, and academic performance”, Anne Wheaton, the lead author and epidemiologist in the CDC’s Division of Population Health, said in a statement. “Early school start times, however, are preventing many adolescents from getting the sleep they need”.
