Late Night Cell use Cuts Into Teens' Sleep
Researchers in Belgium reported 62 percent of adolescents use their cell phones after bedtime. They attribute cell phone use to 35 percent of cases of adolescents being tired, with levels of exhaustion varying based on the frequency of late-night use and how late into the night teens are talking and texting.
Sleep experts in the United States said these statistics hold true for teens here, too. "The cell phone, not only with speaking, but with the text messaging, interferes with sleep," William Kohler, M.D., medical director of the Florida Sleep Institute in Spring Hill, Fla., told Ivanhoe.
