Teens in the United States spend about nine hours per day online, according to a recent report by Common Sense Media. According to the "Being13" study from CNN, it's largely due to a "need to monitor their own popularity status, and defend themselves against those who challenge it on social media." Not surprisingly, this constant vigilance can lead to major stress and anxiety for teens. On the flip side, this same CNN study said teens use their phones to talk about schoolwork, plan social events and be kind to each other. So what's a parent to do? Lauren's guest Delaney Ruston is a primary care physician and filmmaker who explores these questions with her own daughter in the new film "Screenagers." The film is available for screenings in schools, community groups, offices, PTAs, girl scout troops and more.
