New Study Reveals Alarming Link Between Social Media Use and Teen Mental Health A recent study published in the journal Cyberpsychology, Behavior, and Social Networking has made a disturbing discovery: excessive social media use is linked to a significant increase in depression, anxiety, and loneliness among teenagers. The research, which analyzed data from over 1,000 adolescents, found that teenagers who spent more than three hours a day on social media were more likely to experience mental health issues. As social media continues to play an increasingly dominant role in the lives of young people, experts are sounding the alarm about the potential long-term consequences of excessive social media use on mental health.
