Frequent use of social media does damage the mental health of teenage girls but it causes harm indirectly through cyberbullying， sleep loss and reduced physical activity，rather than directly by affecting brain development.

That conclusion comes from the first detailed study of how social media affects the mental health of young users， carried out by researchers from Imperial College and University College London and published in The Lancet Child & Adolescent Health journal.

The study examined lifestyle， health， wellbeing and use of technology in almost 10，000 adolescents in England over three years aged 13?16. During this period， frequent users of social media in the research rose from 43 percent to 69 percent of boys and from 51 percent to 75 percent of girls.

Statistical analysis of the results showed that more participation in social media was associated with greater psychological distress in both sexes， though the effect was more than twice as strong as in girls. Almost all the harm was caused by three factors： Most important was cyberbullying， followed by loss of sleep and then reduced physical activity.

“Social media itself doesnt cause harm， but frequent use may disrupt activities that have a positive impact on mental health like sleeping and exercising. Meanwhile， increasing exposure of young people to harmful content， particularly the negative experience of cyberbullying is also a concern，” said Russell Viner， professor at the UCL Great Ormond Street Institute of Child Health， who led the research.

“Parents need to know what their childrens social environment is online as well as in the real world，” said co?author Dasha Nicholls of Imperial College. That means that some parents should change their message. She added，“Rather than constantly saying ‘Get off your phone， get off your phone！， insist on your kids leaving their phone downstairs when they go to bed. Then they cant be bullied while theyre in bed and they will sleep better.”

Although the researchers said the study was the best available analysis of the effects of social media on teenagers， it still had many limitations. For example the data showed how frequently the subjects accessed or checked social media but not how long they spent doing so.
