Social media has become an integral part of modern media and communication. It provides various uses and gratifications for users such as social interaction, information seeking, entertainment, and expressing opinions. However, excessive social media use can negatively impact teenagers' mental health and academic performance. Studies show that teens who use social media for more than two hours daily report higher rates of poor mental health, psychological distress, and lack of sleep. While social media is not inherently bad, moderation is important to reap benefits and avoid potential downsides.
