Nowadays, in public or private places, we tend to scroll mindlessly through our social media feeds when we have a few spare minutes (or for some, hours). And as we probably know intuitively, and as the research is confirming, it is not the best habit when it comes to our collective psychology. The American Academy of Pediatrics has warned about the potential for negative effects of social media in young kids and teens, including cyber-bullying and "Facebook depression." But the same risks may be true for adults, across generations. A review study suggests "Facebook Addiction Disorder" because addiction criteria, such as neglect of personal life, mental preoccupation, escapism, mood modifying experiences, tolerance and concealing the addictive behavior, appear to be present in some people who use social networks excessively. A study also shows when people stop using the Internet, they also undergo small but measurable physiological effects. Rather than enhancing well-being, as frequent interactions with supportive offline social networks powerfully do, the current findings demonstrate that interacting with Facebook may predict the opposite result for young adults—it may undermine it. In fact, another study found that social media use is linked to greater feelings of social isolation, mentally and physically. Facebook is also a jealousy generator. We fall into the trap of comparing ourselves to others as we scroll through our feeds, and make judgments about how we measure up. One study looked at how we make comparisons to others posts, in "upward" or "downward" directions—that is, feeling that we are either worse or better off than our friends. It turned out that both types of comparisons made people feel worse, which is surprising, since in real life, only upward comparisons (feeling another person has it better than you) makes people feel bad. But in the social network world, it seems that any kind of comparison is linked to depressive symptoms. All of this is not to say that there is no benefit to social media—obviously it keeps us connected across great distances, and helps us find people we had lost touch with years ago. But getting on social networks when you have some time to kill, or, worse, need an emotional lift, is very likely a bad idea. If you are feeling brave, try taking a little break, and see how it goes. And if you are going to keep "using," then at least try to use in moderation.
