Assignment THANK YOU! Social Media and Teen Health Like most teenagers, much of the socializing these students at Blackburn College do is online. “And then you realise, oh no, it’s 2 o’clock in the morning and I’ve got an exam...” But the British Psychological Society has raised concerns that late nights spent maintaining social media profiles could be detrimental to their health. “Most people use social media nowadays so it’s very easy to become too invested in having to keep updating and liking pictures, and responding to people online.” “Many people post pictures of themselves which can quite easily not peak people’s confidence.” “Seeing posts of people and like, their lives, and comparing your life to other people’s lives, and maybe it’s not as exciting or not as successful and it might put yourself down.” Researchers think that it’s not just the lack of sleep caused by late nights online that are causing these issues but that it’s the emotional investments in maintaining a 24/7 social media profile that could also be a major factor. That comes from research carried out at the University of Glasgow. [Dr Heather Cleland Woods, Lead Researcher, Glasgow University.] “We saw that overall, social media use was related to someone’s anxiety, and their depression. They want to be online 24/7. And as that need increased, then we also saw that that had an impact on their sleep quality?” Here at Blackburn, they embrace the technology but try to encourage students to use it responsibly. [Tracy Stuart, Blackburn College.] “What we try to do here is to develop some self-regulation skills in young people so they understand when to turn off, when to turn on, when to make sure that they’ve got all the commitments, all the parts of their lives so that the whole world doesn’t become a virtual world.” The advice of course would be to moderate your social media use. Easy to say, but for many young people, not so easy to do. If they can, they may find themselves looking and feeling much more healthy in their selfies.
