Abstract:
The article examines the impact of excessive use of digital devices on the development of specific pathological conditions in preschool children (3–6 years old). Based on a systematic analysis of modern research, the main diseases associated with prolonged screen time are identified, including obesity, sleep disorders, digital visual fatigue (CVS), motor development delay, and attention deficit hyperactivity disorder (ADHD). The pathophysiological mechanisms of these conditions are described in detail: from neurohormonal shifts to sensorimotor deprivation. Particular attention is paid to preventive measures aimed at reducing the risk of developing these diseases, including screen time regulation, organization of physical activity, and hygiene of the digital environment.
