Shocking Teen Sleep Study

(Philadelphia, Pennsylvania) Researchers at Drexel College of Nursing, led by Dr. Christina Calamaro, have discovered that teens who stay up late at night drinking coffee while surfing the Internet tend to fall asleep during the day.

Of the 100 students ages 12 to 18 studied, 66 percent had a television in their bedroom, 30 percent a computer, 90 percent a cell phone and 79 percent an MP3 digital audio player, Calamaro's team wrote in the journal Pediatrics.

Eighty percent of the teens reported getting less than 8 hours of sleep on a school night, while at least 30 percent reported falling asleep at school. Those who fell asleep at school on average had a caffeine consumption 76-percent higher than those who reported staying awake, she said.

Information on research cost and funding was not reported.
