Social media may present 'profound risk of harm' to children and adolescents' mental health, according to U.S. surgeon general Vivek Murthy, who issued this advisory warning in a recent report, Social Media and Youth Mental Health (http://www.hhs.gov/sites/default/files/sg-youth-mental-health-social-media-advis). Although social media has potential benefits for building diverse and positive connections, a growing body of evidence indicates its use is associated with a multitude of negative effects, including poor sleep, online harassment, poor body image, low self-esteem, and higher depressive symptoms. Adding to the concern, exposure to harmful content has been linked to an increase in adolescent suicide and self-harm. Social media can also expose children and teens to predators. Nearly six in 10 adolescent girls say they have been contacted by a stranger in ways that made them feel uncomfortable or unsafe. The surgeon general's report includes recommendations to help families guide children's social media use, such as keeping mealtimes free of devices, creating a "family media plan" to set boundaries on use, and keeping personal information private.
