Have you ever wanted to tell someone about a tough day at work or scary medical news, but felt nervous about calling a friend to share what's going on?

Findings from a new study suggest that people who feel apprehensive about one-on-one interactions are taking advantage of online social networks to help regulate emotions during times of need.

"When people feel badly, they have a need to reach out to others because this can help reduce negative emotions and restore a sense of well-being," says Eva Buechel, a professor at the University of South Carolina. "But talking to someone face-to-face or on the phone might feel daunting because people may worry that they are bothering them. Sharing a status update on Facebook or tweet on Twitter allows people to reach out to a large audience in a more undirected manner."

Sharing short messages to an audience on a social network, called microblogging, allows people to reach out without imposing unwanted communication on someone who might feel obligated to respond. Responses on online social networks are more voluntary.

To test whether people are more likely to microblog when they feel socially apprehensive, Prof Buechel asked participants in one group to write about a time when they had no one to talk to at a party, while the control group wrote about office products.

Then she asked the participants who had an online social network account to log in and spend two minutes on their preferred social network. When the time ended, she asked people if they had microblogged.

The results showed that those who had been led to feel socially apprehensive were more likely to microblog.

"There is a lot of research showing that sharing online is less ideal than having communication in person, but these social networks could be an important communication channel for certain individuals who would otherwise stay isolated," she says.

She acknowledges that there is a danger for those who start to rely on social media as their only form of communication, but when used wisely, microblogging can be a valuable means of buffering negative emotions though social interaction.

Do you think social media helps people deal with their emotions or do you think it causes more problems than it solves?
