A new study has found that social media can reduce the amount of time that teenagers in Kent spend sleeping and exercising.

Researchers suggest that parents should ban phones after 10PM and encourage children to do more physical activity in order to prevent psychological distress.

So, how can we encourage teenagers to not use social media as much as they currently do? We asked shoppers in Chatham and we were also joined by our KMTV health expert Dr. Julian Spinks to talk more about it.
