As mentioned above, most active users of social networks are teenagers. In fact, it has a huge impact on their lives. In other words, almost every teenager has a profile on each social networking site, and sometimes even more than one profile. They actually spend more than 3 hours a day on social networking sites. This means that teenagers spend more time with their electronic devices than with their family; for example, when I sit with my family watching TV or eating lunch, I actually see my sister spending time on her phone or iPad rather than talking to us or my parents. This reduces important family ties. And they socialize less with others in real life (De Marcellis-Warin, N., Sanger, W. and Warin, T., 2015). One risk associated with social networking sites on teenagers concerns mental and physical health. A study conducted in Norway, for example, states that almost 63% of teenagers are connected to Facebook every day and 40% do so several times a day. Furthermore, it also shows that users become addicted to social networks. In particular. Sampasa-Kanyinga noted that "the use of social networking sites can lead to poor mental health, and poor mental health may be a reason why teenagers use social networks"
