1 . Teens Aren’t Getting Enough Sleep And Schools Are Partly to Blame
Most kids are severely sleep deprived, and early school starting times aren’t helping.
Across the country, only 17.7 percent of middle and high schools start classes after 8:30 a.m.. The average school start time for middle and high schools around the country is 8:03 a.m., according to a new analysis from the Centers for Disease Control and Prevention.
The AAP advises that schools start after 8:30 to help teenagers get 8.5 to 9.5 hours of sleep a night — the amount the AAP says is ideal. Currently, less than a third of high school students sleep 8 hours a night, says the CDC analysis.
The analysis uses 2011–2012 information from the Department of Education to gather the start times of about 39,700 schools. Alaska has the latest average school start time at 8:33 a.m., while Louisiana has the earliest at 7:40 a.m.
Sleep-deprived teenagers are more likely to suffer from depression, use drugs, get low grades and be overweight. Even though schools often face obstacles when trying to delay school start times due to traffic and scheduling concerns, some have made progress recently.
After Deerfield Academy in Massachusetts delayed school start times in 2008 from 7:55 a.m. to 8:30 a.m., the private school saw a number of benefits. As the Huffington Post previously reported, the school’s 2014 viewbook noted that students earned higher grades; ate more breakfasts, visited the health center far less frequently; and performed better in athletics. Teachers reported that first-period discussion classes were uncharacteristically lively from the beginning bell.
Half of parents whose teens attend schools that start before 8:30 would support a later start time, according to a 2014 survey from the University of Michigan C.S. Mott Children’s Hospital.
