One 2015 study by psychologists at Pace University in New York found that Instagram can have negative associations with depressive symptoms for adults aged 18-29 (although this correlation was reduced in users who followed people they knew in real life, rather than lots of strangers).

Another study, published in the Journal of Social and Clinical Psychology, showed a correlation between time spent on Facebook and depressive symptoms.

Celebrities such as Fearne Cotton, Anne Hathaway and Emma Watson have also spoken out about how they have experienced the relationship between social media and mental health.

“Social media is a tricky one because I love it and I dislike a lot of it as well,” said Cotton in February.

“I like the fact that it gives me a control as to what I would like people to see of me, it’s less hearsay, less second-hand news. But the bit that is dangerous, especially for younger women, is looking at other people’s lives and doing that awful ‘compare and despair’ sort of thing.

“You put your own life against others and [sometimes you start] believing in the fantasy that you see.”
