The Internet also makes it easy to stay in touch with friends, even if they move to different cities. However, there are also problems. Some teenagers spend too much time on social media. They check their phones hundreds of times a day, which makes it hard to focus on homework or sleep. Some even feel sad or worried when they see other people’s “perfect” lives online. There are also safety risks: sharing personal information or talking to strangers can lead to trouble. To use the Internet well, teenagers need to learn balance. They should set a time limit for online activities, choose safe websites and remember that what they see online is not always real.
