AMA urge for later school start times to avoid teen sleep deprivation
The American Medical Association (AMA) urges starting school times later in the morning so teenagers can get enough sleep.
The AMA said in a new policy that middle and high schools should start at 8:30 AM at the earliest because research has shown that puberty is accompanied by a biological shift in circadian rhythm that contributes to later bedtimes and wake-up times in adolescents. They said nearly 10% of US high schools today begin at or before 7:30 AM as districts try to make time for additional classes, sports and extracurricular activities.
Inadequate sleep has been linked to a host of mental and physical problems, from poor memory performance and mood disorders to impaired immune function and unhealthy body mass index, the AMA said.
“Sleep deprivation is a growing public health issue affecting our nation’s adolescents, putting them at risk for mental, physical and emotional distress and disorders,” said Dr. William Kobler, an AMA board member. “Scientific evidence strongly suggests that allowing adolescents more time for sleep at the appropriate hours results in improvements in health, academic performance, behavior, and general well-being,” he added.
Only 32% of American teens in a recent study reported getting at least eight hours of sleep on an average school night. The American Academy of Pediatrics recommends teenagers between 14 and 17 years old should get 8.5 to 9.5 hours of sleep per night.
The AMA’s new policy, adopted at the group’s annual meeting in Chicago, also encourages physicians to educate parents, school administrators and teachers about the importance of sleep for adolescent mental and physical health.
