The rapid expansion of digital technology has transformed modern life, but it has also given rise to a growing mental health concern: digital addiction. Countries such as South Korea, the United States and the United Kingdom are at the forefront of research into the psychological and neurological effects of excessive screen use.
Digital addiction encompasses a range of behaviours, including compulsive use of social media, online gaming and continuous smartphone engagement. Studies suggest that these behaviours are associated with increased levels of anxiety, depression and sleep disturbances, particularly among adolescents and young adults.
In South Korea, where internet usage rates are among the highest globally, government-led initiatives have been implemented to address screen dependency. These include counselling programmes and digital detox camps aimed at young people. In the United Kingdom, mental health professionals are increasingly incorporating assessments of digital habits into clinical practice.
Neuroscientific research in the United States has begun to explore how prolonged screen exposure may affect brain function, particularly in areas related to attention, reward processing and impulse control. Findings indicate that excessive digital engagement may alter dopamine pathways, reinforcing addictive behaviours.
Despite growing awareness, experts caution that digital technology also provides significant benefits, including access to information, social connectivity and healthcare services. The challenge lies in promoting balanced usage while mitigating potential risks.
