When we log onto one of our all-time favorite social media sites, Facebook, we browse through photos, status updates and upcoming events, and check to see if we received any notifications or messages. After we log off, we feel good about the 26 likes we received on the photo we posted of last week's trip to the beach, or we're ecstatic because we received an invite to Saturday's hottest party in Hollywood - right? Wrong.

According to a University of Michigan study, researches found that Facebook users felt worse about themselves after browsing the social media site.

"The more you used Facebook, the more your mood dropped," said Ethan Kross, the lead author of the study.

Apparently, Facebook can make you feel jealous of other people's lives and leave you feeling small or diminished. And for those who have low self-esteem, a Facebook profile won't necessarily make you feel any better. On the positive side, other studies have proven that looking at our own Facebook profiles can be self-affirming, and can increase life satisfaction, social trust, civic engagement and political participation.

So what does this mean?

"One of the things we don’t know is what aspect of Facebook use is contributing to these results,” said Kross, meaning more research needs to be done to explain these findings.
