Teens Increasingly Sleep Deprived
A new study found that female students, racial/ethnic minorities, and students of lower socioeconomic status are less likely to report regularly getting seven or more hours of sleep each night compared with their male counterparts, non-Hispanic white teenagers, and students of higher socioeconomic status, respectively. The largest decrease in the percentage getting seven hours of sleep per night was 15-year-olds, a particularly concerning trend for students at this important juncture in development.

Detach the cell phone/Ipod from their heads and send then to bed perhaps they might sleep. A second issue that maybe a reason I have noticed in my area is your teen girls tend to look for work and still pour great effort into their studies. The male teens do not seem to worry as much about work till later. So maybe they are just busy trying to save for school and keeping up the grades to get in.
At that age they feel their missing something all the time. They need to keep up with trends, fads and friends - that's a lot of work and also a lot of time. Its a seriously bad investment in a world that demands only experts in the workplace. Flipping burgers is the next option for the sleepy heads.
