Teens on average are now getting less sleep than ever. And according to a nursing professor at Villanova University, the sleep many do get is interrupted by texting.

Elizabeth Dowdell tells CBS "The phone will beep, they'll answer the text and either respond in words or gibberish." She also says that sometimes the messages are unintentionally inappropriate. Dowdell adds "Once awake, the texter has no memory of sending the messages."

This came about as the result of a study done at the university on teen sleep habits. The recommendation is that teens put their mobile devices out of reach when it comes time for sleep.
