Social media may do more harm than good when it comes to personal well-being, a small study from the University of Salford in the UK indicates. About half of the survey’s 298 participants, all of whom identified themselves as social media users, say that their use of social networks like Facebook and Twitter makes their lives worse. In particular, participants noted that their self-esteem suffers when they compare their own accomplishments to those of their online friends. In addition to confidence issues, two-thirds claim they find it difficult to fully relax or sleep after spending time on social networks. A quarter cited work or relationship difficulties due to online confrontations. And more than half say they feel “worried or uncomfortable” at times they are unable to access their Facebook or email accounts.
