Teens are known for being dependent on their cell phones -- exchanging as many as 60 text messages a day -- but are they so attached to their devices that they'll respond to texts while they're sleeping?
Yes, say some experts -- and the behavior is becoming more common.
Earlier this week, a CBS affiliate in Philadelphia spoke with Dr. Elizabeth Dowdell, a professor of nursing at Villanova University, who believes that more and more teens may be texting in their sleep
"It's something new. We're just starting to get a handle on it," Dowdell told The Huffington Post. "I think that we will start to see more of this as cell phones become much more accessible at all ages."
With sleep texting, the beep of a cell phone lightly awakens a person, so he or she will reach over and respond to a message (sometimes with jibberish). However, the person has no memory of having done so in the morning.
Dowdell explained that while she has not conducted research on this particular phenomenon, she's seen enough anecdotal evidence to suspect that it is on the rise.
