The rapid advancement of digital technology has transformed the way teenagers communicate, learn, and interact with the world. However, excessive technology use has also been associated with behavioral addiction, psychological distress, and difficulties with cognitive functions. Prolonged screen time and constantly switching between different digital activities may also affect certain cognitive functions. These findings suggest that excessive and unregulated technology use may hinder adolescents' cognitive growth.

Digital addiction refers to the excessive or compulsive use of digital devices and content despite negative effects on everyday life. For teenagers, this may include constantly checking phones, scrolling for long periods, playing games longer than intended, or using devices late at night. The concern begins when digital use interferes with schoolwork, sleep, relationships, and responsibilities. Digital addiction also reduces a teenager's ability to focus. Constantly checking notifications while studying interrupts concentration and makes information harder to understand and remember. Long hours of screen use can also affect sleep, and since sleep is essential for learning and memory, poor sleep may further weaken academic performance and cognitive functioning.

Social media pressure is considered one of the major contributing factors to digital addiction. The idealized portrayals of appearance, success, and lifestyle on social media encourage adolescents to compare themselves with unrealistic standards, increasing their risk of anxiety and depression.

Meanwhile, cognitive development refers to the growth of mental abilities such as attention, memory, learning, problem-solving, decision-making, and self-regulation. During adolescence, these abilities are still developing, making teenagers more vulnerable to the effects of unhealthy digital habits.
