We weren't expecting this one.

For a long time social media has been blamed for affecting people's mental health. We all know that what we see on any social media platform is never the full truth. People hide the mundane parts of their lives, they photoshop and they edit. But it turns out there's one social networking site that trumps the rest for all those fussy, feel-good vibes... and we wouldn't have expected it to be honest. According to a new study, it turns out that Facebook is the best form of social media for your mental. However, it's not just likes and shares that will do it for you, it's actually engaging with people in the comments section and on messenger. Moira Burke told Eurekalert that it doesn't even have to be anything much, just personalised comments here and there can give people a serious lift. “We’re not talking about anything that’s particularly labour-intensive. This can be a comment that’s just a sentence or two. “The important thing is that someone such as a close friend takes the time to personalise it. The content may be uplifting, and the mere act of communication reminds recipients of the meaningful relationships in their lives.”
