In an experiment conducted by the Happiness Research Institute in Denmark, results show that people got happier, more social, productive, present and less stressed by stop using Facebook for one week.

Researchers in Denmark who split 1,095 daily Facebook users into two groups, half given access to the site as normal and the remainder forced to quit cold turkey, found that after a week those on a break from the social network felt 55% less stressed.

"We look at a lot of data on happiness and one of the things that often comes up is that comparing ourselves to our peers can increase dissatisfaction," said Meik Wiking, CEO of the Happiness Research Institute in Copenhagen.

"Facebook is a constant bombardment of everyone else's great news, but many of us look out of the window and see grey skies and rain (especially in Denmark!)," he said. "This makes the Facebook world, where everyone's showing their best side, seem even more distortedly bright by contrast, so we wanted to see what happened when users took a break."
