@pbsnews: As surveys show a majority of American teens use social media in some form, some studies have linked more than three hours a day on the sites to an increased risk of anxiety and depression. But what can parents do about their kids using social media? U.S. Surgeon General Vivek Murthy shared his advice on teen social media use with PBS NewsHour's Amna Nawaz. "For parents whose kids are already on social media, what I recommend to them is to create tech-free zones in their children's life, to protect sleep, in-person interaction, and physical activity," Murthy said. On Monday, Murthy called for warning labels on social media platforms in an op-ed in the New York Times. #tiktok #murthy #socialmedia #mentalhealthtiktoks #MentalHealth #anxiety #depressionanxiety #depression #pbsnews #newshour #pbsnewshour #childmentalhealth #socialmediamentalhealth
