For decades, the amount of sleep people get at night has been decreasing. Teenagers are no exception. Once upon a time, they listened to baseball games with a radio under their pillow or read comics under the covers. Today teens have a wider array of nighttime activities available: Internet, texting, videos, DVDs and MP3 players, to name a few. While this variety may make their parents envious, it also cuts down on how much sleep teens get at night. Many studies have shown that people don't function as well on limited sleep. Some studies suggest that teens may need more than eight hours of sleep at night for good health. They don't seem to be getting it.
Not surprisingly, they found that the teens who spent the most time using electronic devices at night were the ones who slept the least.
