As happy moments from other people’s lives fill your Facebook newsfeed and other social networking sites, researchers are now saying there is evidence that comparing your life to others online can undermine your well being. A new study from University of Houston researcher Mai-Ly Steers notes that making social comparisons is inevitable for Facebook users, but that it is important to remember that most people only post about good things happening in their lives and not the bad. The study found that young people or people going through emotional difficulties are particularly vulnerable to feeling depressive symptoms due to social comparisons.
