Sleep texting is becoming a growing problem among teens.   Villanova University professor Elizabeth Dowdell says, “It’s just   what you’d think it is, it’s texting while asleep. It’s exactly   what is sounds like, or really more between that, you know, that area between   being asleep and being awake. The phone will beep, they’ll answer the text.   They’ll either respond in words or gibberish. (It) can even be inappropriate.   Ex-girlfriends contacting ex-boyfriends, saying ‘I miss you. I want to   see you.’ The thing that happens, though, is that when they wake up, there’s   no memory. Overplugged and overextended teens and young adults tend to get less   than that so this interrupts what could be a good night’s sleep, because   they’re an hour-and-a-half or two hours into their sleep cycle, and they’re   answering texts or the machines are beeping at them. Sleep interruption can   lead to obesity, depression, failing grades and more.''
