The Happiness Research Institute conducted an experiment on 1,095 people in Denmark. Half of the participants were asked to refrain from using Facebook for one week, while the control group continued their social media activities as usual.
At the end of the week, the participants were asked to evaluate their life satisfaction on a scale of one to ten both before and after the one-week experiment.
The researchers found a significantly higher level of life satisfaction among those who did not visit Facebook.
However, the other group saw life satisfaction shoot up from 7.56 to 8.12 after their Facebook-free week, the 'Local' reported.
People on Facebook were 39 per cent more likely to feel less happy than their friends. They were also 55 per cent more likely to feel stressed.
The control group also reported feeling angrier and lonelier than those who did not use Facebook, researchers said.
Meik Wiking, CEO Happiness Research Institute said that the experiment's results were largely down to people's tendency to compare themselves to others.
"If we are constantly exposed to great news, we risk evaluating our own lives as less good," Wiking said.
