This chapter explores the dangers of cybercrime and how to keep children's health and safety online. The risks of cybercrime and exposure to cybersecurity threats have grown with adolescent technology use. The study examines the dangers linked to social media sites, including cyberbullying, exposure to objectionable material, and unrealistic expectations, which may impact children's mental health and general well-being. Limiting children's use of social media and educating parents about potential cyber-psychological risks and public health hazards are just a few of the methods suggested in the piece to keep kids safe and healthy online. The study also emphasizes the need for parents, researchers, and others to take proactive steps to protect adolescents from the mental health risks and public health hazards associated with excessive online use. The methodology used in the chapter is a narrative review of the literature, consolidating and synthesizing the findings of various discussions' conclusions into one relevant and comprehensive debate.
