Important tool as social media are, their negative influence can’t be neglected. First, when teens use social media, they are likely to have trouble concentrating on their schoolwork. Besides, too much time spent using social media may decrease their real life communication. What’s worse, constant exposure to the fantasy world tends to harm teens’ self-dignity and hence leads to a lack of self-confidence, let alone the unhealthy information.
