Internet addiction is a growing problem these days, especially in young children who seem to be more vulnerable than adults as they are more often exposed to smart devices.
Many experts say that parents can help their children with Internet addiction by paying attention to how much their kids use the Internet.
"Those addicted to the Internet often become anxious and depressed if they are deprived of Internet access," said Bae Joo-mi of the Korea Youth Counseling and Welfare Institute. "Continued abuse of the Internet will make daily life difficult without it."
According to a survey, middle and high school students that spend more than five hours a day on the Internet are at high-risk for addiction, and the same goes for elementary school students that spend over two hours a day online.
"Parents should monitor if their kids are overly exposed to the Internet if they often doze off in class or tend to stay home alone instead of playing with their friends or participating in other social activities," Bae said.
