Abstract: Generation Z (born ~1995-2010), the first generation to grow up in the digital age, spends significant time online, which has raised concerns about technology addiction and its effects on mental health and social behavior. This article investigates the online behaviors of Gen Z youth and the phenomenon of technology addiction, using current academic sources and a mixed methodology (quantitative and qualitative). Typical digital habits are analyzed – from extensive use of social media and digital multitasking, to manifestations such as disconnection anxiety (nomophobia) and fear of missing out on online information or events (FOMO). The impact of technology on mental health (e.g. increased levels of anxiety, depression, stress), on social relationships (e.g. the phenomenon of phubbing - ignoring interlocutors in favor of the phone - and changing socializing patterns) and on academic performance (difficulties concentrating, decreased attention and negative effects on school results) among Generation Z is also examined. The conclusions highlight the need to develop strategies for balanced use of technology and promote digital literacy, in order to capitalize on the benefits of the online environment while reducing the risks associated with technology addiction among Generation Z.
