The research, which tracked 5000 US adults for three years between 2013 and 2015, compared users’ Facebook habits against information on their physical and mental health, weight, and general well-being. Worryingly, it found that for every 1% rise in the number of ‘Likes’, link clicks and status updates a user made, their self-reported mental health dropped by 5-8%.
Looking at how Facebook’s impact compares with real world interactions, the study showed that actually meeting friends had the opposite effect, lifting users’ moods by a similar figure.
