A study by two German universities found that Facebook brings out the green-eyed monster in many of us. One in three felt worse after using the social network. Those who browsed but didn’t post anything were most affected. The primary culprit: Other people’s vacation photos. Many also felt bad about themselves when they saw the number of Likes or birthday greetings they got in comparison with others. (You can read the study’s abstract here.)
If you check your Facebook account automatically or often, you may want to start considering your frame of mind before logging in.
