Study: Most teens start school too early in morning to get enough sleep

Most teens start school too early in the morning, which deprives them of the sleep they need to learn and stay healthy, a new study says.
The American Academy of Pediatrics last year urged middle schools and high schools to start no earlier than 8:30 a.m. in order to allow teens — who are biologically programmed to stay up later at night than adults — to get the recommended 8.5 to 9.5 hours of sleep each night.
But 83% of schools do start before 8:30 a.m., according to a study released Thursday by the Centers for Disease Control and Prevention. The average start time for 39,700 public middle schools, high schools and combined schools was 8:03 a.m., based on data from the 2011-2012 school year.
