Widespread use of smartphones and social media among children is causing a significant increase in depression, anxiety, and suicide, according to top American lawmakers and experts. Senator Ted Cruz highlighted that children aged 8 to 12 spend an average of 5.5 hours daily on screens, while teenagers spend over 8.5 hours, with more than half of a teenager’s waking hours spent on screens, a concerning trend for parents and educators.
Psychologist Jean Twenge informed lawmakers that the youth mental health crisis escalated notably after 2012, coinciding with the widespread adoption of smartphones and the shift of social media from optional to almost mandatory for adolescents. Twenge noted a doubling of clinical-level depression among adolescents and young adults between 2011 and 2019, along with increased emergency room visits for self-harm and suicide rates among teenage girls.
Highlighting the deliberate design of social media platforms to capture attention, Ranking Member Maria Cantwell referenced studies showing that teenagers spend over an hour daily on smartphones during school hours, particularly on platforms like Instagram, TikTok, and YouTube. Research has linked heavy social media use to higher rates of anxiety, depression, and isolation among youth, with approximately 40 percent of teens displaying concerning media addiction patterns.
Pediatrician Jenny Radesky raised concerns about digital products not being designed with youth development in mind, emphasizing that many were initially created for adults and later adapted for children. She warned that features like frequent notifications and algorithmic feeds make it challenging for children to disconnect, impacting their sleep, homework, and family interactions negatively.
Lawmakers expressed worries about schools exacerbating the issue by providing internet-connected devices to students without adequate safeguards. Senator Cruz pointed out the challenges parents face in managing screen time when children are required to use devices for schoolwork, emphasizing the need to assess the impact of technology in classrooms on learning outcomes and potential harms.
Experts cautioned that reduced face-to-face interaction and sleep deprivation are compounding the crisis, with teens spending less time with friends in person and getting less sleep than previous generations. They also highlighted concerns that as artificial intelligence becomes more integrated into platforms used by children, exposure to addictive and emotionally manipulative content may increase.
