The generation of ''digital natives'', born between the end of the last century and the beginning of the current one, has been growing up surrounded by a screen in every part of their lives: screens are used to study, for entertainment, and social activities. Children in the age 8-18 spend, on average, 7.5 hours every day in front of a screen, 4.5 of which are spent watching TV. The effects of screen time activity on their mental health and brain structure are still not fully understood, and evidence for an impact of screentime on the health is inconsistent, with systematic reviews showing mixed findings.
