The article consists of an essay that examines the growing problem of internet and social media addiction among teenagers and students, often referred to as „digital natives” or „iGen”. It explores how excessive use of digital platforms affects adolescents’ social behavior, brain functioning, and relationships with peers, teachers, and family. Several studies show that increased screen time, often between 6 and 9 hours a day, is correlated with mental health problems such as anxiety and depression. Although the use of social media satisfies the needs of belonging and self-presentation, it can lead to a phenomenon of de-individuation among students. The article acknowledges the potential benefits, including access to global knowledge and building an online community. At the same time, it highlights significant negative effects such as reduced social connections, emotional instability and difficulty managing conflicts. In particular, the symptoms of addiction often mirror those of gambling addiction. Teachers face increasing challenges with students’ short attention spans and declining academic performance. Excessive use of social media poses substantial risks to students’ mental health, cognitive capacities and social skills, a fact that teachers and parents must be aware of and act accordingly by implementing appropriate strategies based on the latest scientific evidence.
