You check it in the bathroom. You check it at the movies. You check it when you’re having dinner with your friends. But you wouldn’t say you’re addicted—and most experts would agree with you.
“Only a small percentage of people qualify as addicted,” says Dr. David Greenfield, assistant clinical professor of psychiatry at the University of Connecticut and founder of the Center for Internet and Technology Addiction. “But many people overuse their smartphones.”
The line between overuse and addiction is gray. But Greenfield says you’re moving into addiction territory when you can’t stop using your phone even when it’s harming your life. Whether you’re in a work meeting or behind the wheel, “if you can’t help being on it even when you know you shouldn’t be, that loss of control is the hallmark of an addiction,” he says.
