Waking up Teens -- Scientists Show Blue Light Can Help Reset Sleep Cycle

Waking up Teens -- Scientists Show Blue Light Can Help Reset Sleep Cycle:

"Teenagers' morning drowsiness is often caused by out-of-tune body clocks, in a condition known as 'delayed sleep phase syndrome.' Scientists now say that timing exposure to blue light -- avoiding it during the first two hours of being wake, then getting a good dose of it -- can help restore the sleep cycle, so teens feel sleepy earlier at night and are more awake in the morning."
