While studies show that both adults and teens in industrialized nations are becoming more sleep deprived, the problem is most acute among teens, said Nanci Yuan, MD, director of the Stanford Children’s Health Sleep Center. It’s a problem that knows no economic boundaries. Sleep deprivation increases the likelihood teens will suffer myriad negative consequences, including an inability to concentrate, poor grades, drowsy-driving incidents, anxiety, depression, thoughts of suicide and even suicide attempts. According to a 2006 National Sleep Foundation poll, the organization’s most recent survey of teen sleep, more than 87 percent of high school students in the United States get far less than the recommended eight to 10 hours, and the amount of time they sleep is decreasing - a serious threat to their health, safety and academic success.

She is desperately tired and longs for sleep. For 10 minutes or so, she just sits at her desk and cries, overwhelmed by unrelenting school demands. Carolyn Walworth, 17, often reaches a breaking point around 11 p.m., when she collapses in tears.
