Almost 90 per cent of users access the site to look at their own wall posts, and three quarters look at their own photos when they are feeling low, the study has found.
Dr Alice Good, of the University of Portsmouth, found that this kind of 'self soothing' use of Facebook is actually beneficial to the user's mood, especially if they are prone to feeling low.
This directly contradicts previous research that has suggested that looking at Facebook can be bad for your mental health.
"We were very surprised by these findings, which contradict some recent reports. Although this was only a small study, we will go on to study larger groups to see if the results remain consistent," Good said.
Good quizzed 144 Facebook users and found that people often use the social network to reminisce, using old photos and wall posts as a form of comfort.
Looking back at older photos and wall posts is the main activity, and the one that made them happiest.
