Health authorities have issued a comprehensive warning regarding the physical and psychological impacts of intensive screen exposure on children and adolescents, detailing specific risks that vary across different developmental stages from early childhood through the teen years. According to official reports, health officials caution that certain impacts resulting from heavy digital device usage can become irreversible, necessitating a coordinated global response that places young individuals at the center of prevention efforts.
New Digital Health Guidelines Grounded in Scientific Research
The updated findings come from a specialized digital health framework developed by regional health authorities, drawing from an extensive analysis of 700 scientific studies. According to the department’s deputy director general for addictions, Lluïsa Conejos, the updated guidelines build upon previous evaluations to categorize physical, psychological, and social risks clearly by age groups, highlighting issues such as developmental delays, dental cavities, myopia, sleep disorders, emotional distress, and digital violence.
Statistical data cited in the assessment reveal that digital technology is deeply embedded across the broader population, with 99 percent of individuals aged 16 to 74 owning an electronic device and 96 percent using one weekly. Among youth, 82.4 percent own a personal mobile phone. Furthermore, the average age for acquiring a first mobile device sits at 10.8 years old. Ownership rates climb steeply through the educational journey, with 51.6 percent of primary school students owning a phone, a figure that jumps to 92.8 percent among secondary education (ESO) students.
Developmental Risks Across Age Brackets
The health guidance systematically breaks down the impacts of screen time according to critical developmental windows. For infants and toddlers aged zero to six, improper technology use can contribute to delayed language and motor skill development, altered circadian rhythms, cognitive and emotional changes, sedentary behavior leading to weight gain, myopia, and a reduction in face-to-face interactions.
In the 7-to-11 age bracket, screens interfere with academic learning, increase the risk of myopia and excess weight, disrupt sleep patterns, and trigger emotional distress. Notably, specialists highlighted an unexpected correlation between screen exposure and dental cavities. According to health officials, this link stems directly from the consumption of sugary drinks and foods while operating screens.
For adolescents aged 12 to 18, risks shift toward emotional well-being, body image distortion, diminished personal self-worth, and heightened vulnerability to harassment and bullying both on and offline. Data outlined in the guidelines indicate that teenagers aged 14 to 18 spend an average of 4.8 hours per day on internet leisure activities during weekdays, escalating to 6.7 hours on weekends.
Digital Habits and Compulsive Usage Indicators
Video games and social media command a significant portion of youth screen time. Research indicates that 84.9 percent of young people play video games—breaking down to 97 percent of boys and 72.8 percent of girls. Additionally, one in two boys spends more than two hours daily gaming, compared to one in seven girls.
Social media engagement is similarly widespread, with 74 percent of adolescents dedicating two or more hours to platforms on weekdays, a figure rising to 88 percent over the weekend. Data analysis uncovered that 34 percent of students aged 14 to 18 exhibit a potential problematic use of social networks, characterized by loss of control, persistent usage, excessive preoccupation with staying connected, and psychological distress when disconnected.
Conejos noted that internet usage shows compulsive traits in 23 percent of adolescents, marked by reduced sleep and less time spent interacting with others. Meanwhile, indicators pointing toward video game addiction reach 10.7 percent among boys and 2.2 percent among girls. Health representatives emphasize the urgent need to delay the acquisition of personal mobile devices, arguing that many children enter social media environments before they possess the cognitive maturity required to discriminate and discern digital risks.
