The problem with instagram and other similar sites is that it has been proven to damage self esteem especially in the 18-25 year old range. Young people scroll through looking at people with seemingly perfect lives and feel that if their life doesn't match - its lacking. Studies have found that depression has been linked to spending long hours on these sites and negative body image - especially in young girls.
The influencers are heavily filtered and edited and it gives - people ( mostly girls again) unrealistic beliefs and ideas in that this is how they should look.
British fashion photographer John Rankin Waddell did a really interesting series of images where he asked young people to take a selfie then it it to make it more 'more media friendly'. The girls images where much. more dramatically changed and the series was called "visual diet' and looked at how images can affect our mental health.
The biggest danger of exaggerated body ideals is the very real issue of eating disorders and the heightened risk of body dysmorphia.
Facebook, insta, ticktock have all been designed to make people addicted to them. Facebook even knows when you havnt logged on for a while and will send you a random push notification to bring you back in - twitter and insta are the same.
To be honest I think there should be a big push from the government to encourage people to put their phones down and break the habit.
Porn is so easily accessible to young children through mobile devices, I do worry for my daughters and what there first sexual experience will be. Will the boy she chooses expect her to have no public hair, like anal sex and behave like a porn star in bed. It is worrying.
I think the smart phones have been a curse on society over all actually.
