The impact of digital devices on childhood and adolescence is one of the most relevant debates for families, teachers, and healthcare professionals. The use of smartphones and tablets, although inevitable in today's world, must be carefully regulated to protect children's cognitive, emotional, and social development. The Health Promotion Committee (CPS) of the Spanish Association of Pediatrics (AEP), together with various international institutions, has warned about the risks associated with excessive screen use and has developed comprehensive recommendations to help parents and teachers set healthy limits.
Why is it important to limit smartphone and tablet use in children?
Screen time has immediate and long-term effects on children's health. Several studies show that prolonged exposure to smartphones and tablets can cause:
- Problems in brain development: Premature and excessive use can hinder natural brain development, leading to attention deficit, cognitive delays, and learning problems.
- Sleep disorders: Blue light from screens interferes with melatonin production, causing insomnia and making it difficult to rest.
- Changes in behavior and socialization: Overuse limits personal interactions and can encourage passivity, making it difficult to regulate emotions and learn social skills.
- Risk of obesity and sedentary lifestyle: Sedentary screen time replaces the physical activity essential to preventing childhood obesity and other health problems.
The situation is exacerbated in family settings with difficulties in reconciling work and family life or with an excessive presence of technology in the home, where screens replace games and shared activities. In fact, it is estimated that nearly 45% of children up to five years old use a smartphone or tablet daily, and many start or end the day with these devices, according to recent studies in Spain.
Risks associated with excessive use of digital devices in childhood
Scientific evidence warns of the following consequences when spending more time on smartphones and tablets than experts recommend:
- Attention deficit and overstimulation: The rapid succession of stimuli in applications and digital content can overload the nervous system, increasing the sensitivity threshold and making it difficult to concentrate.
- Sleep disturbances: Exposure to screens before bed reduces the quantity and quality of sleep, harming mood and academic performance.
- Vision problemsMyopia and dry eyes have increased considerably, partly due to the overuse of screens from an early age.
- Sedentary lifestyle and obesityReplacing physical play and outdoor activities with digital entertainment encourages a sedentary lifestyle, which puts our metabolism and cardiovascular health at risk.
- Addictive behaviors and loss of self-control: The immediate rewards and addictive nature of many games and apps make it difficult to self-regulate emotions and manage time.
- Literacy and language difficultiesChildren who spend more time in front of screens show poorer development in expressive language, reading and writing, as well as slower speed in processing information.
- Risk of cyberbullying, exposure to inappropriate content, and social isolationUnsupervised use can result in access to dangerous content, increased exposure to cyberbullying, or a loss of interest in face-to-face interaction with other children and adults.
Scientific recommendations on screen time according to age
The proposals of the Spanish Association of Pediatrics, the WHO, the American Academy of Pediatrics and other scientific entities agree on Limit the time spent using smartphones and tablets according to the child's ageWe summarize the most recent consensuses in the following table:
| Child's age | Recommended screen time | Additional recommendations |
|---|---|---|
| 0-2 years | No screens | Prioritize direct interaction, sensory play, and physical activity. Even occasional exposure can have negative effects on development and sleep. |
| 2-5 years | Maximum 30-60 minutes a day | Always use under supervision, prioritizing educational content and avoiding any violent or inappropriate content. Best used in the company of adults. |
| 6-12 years | Up to 1-2 hours a day | Prioritize family time, physical activity, and parental supervision. Not during mealtimes, never before bedtime, and never in the bedroom. |
| 12-15 years | Maximum 1,5-2 hours of digital leisure time per day | Active parental controls, setting clear limits for social media and video games. |
| 16 years on | Up to 2 hours a day (outside of homework or studying) | Family discussion on responsible use and periodic review of digital habits. |
It's essential not to use screens as a "digital pacifier" to calm, distract, or entertain children in everyday situations such as meals, waiting, or short trips. These opportunities should be used to foster communication, creativity, and autonomy.
AEP Guidelines and the Family Digital Plan
The Spanish Association of Pediatrics, supported by the Spanish Data Protection Agency, promotes the Family Digital Plan, a platform aimed at establishing healthy family routines and criteria for the safe use of technology at home. The plan recommends:
- Limit screen use to what is strictly necessary for education and responsible leisure., depending on the age and development of the child.
- Do not allow the presence of devices in bedrooms or private spaces, preventing isolation and promoting nighttime disconnection.
- Turn off devices that are not in use and avoid the simultaneous use of several devices.
- Avoid screen time during mealtimes or before bedtime, prioritizing family time and rest.
- Design and agree on clear family rules that include adults and minors, setting an example in the responsible use of technology.
- Promote physical activity and outdoor activitiesScreen time should never take away from exercise, personal relationships, or sleep.
Guidelines for healthy, moderate, and supervised use of digital devices
- Use school-owned devices for schoolwork, configured to block inappropriate content and restricted to academic use only.
- Eliminate apps and games that promote immediate gratification or digital addiction, as well as free access to social networks for minors under the recommended age.
- Train teachers, students, and families in risks and good practices relating to health, data protection and cybersecurity.
- Prioritize educational, interactive, and quality content over mere entertainment. Content must be appropriate for the child's age and maturity level.
- Always supervise and accompany use in small children, explaining the content, resolving doubts and taking advantage of the opportunity to discuss.
- Implement parental controls, schedules, and filters that define schedules, applications and pages accessible for each child profile.
- Never leave children under 6 years old alone with a device. nor allow its use as a method to manage tantrums or emotions.
- Encourage physical play, reading and creativity as natural alternatives to digital leisure.
International models: the case of Sweden and educational regulation
Some countries have initiated educational reforms after detecting declines in reading and cognitive skills linked to the intensive use of technology in the classroom.
For instance, Sweden has decided to pause or reverse its digitalization plan for early childhood and primary education., promoting a return to physical textbooks with the aim of ensuring a solid foundation in reading, writing, and arithmetic before introducing digital learning. The goal is Finding a balance between modernization and respect for proven learning rhythms, preventing digitalization from reducing the effectiveness of traditional methods when clear advantages have not been proven.
The Swedish experience reinforces the trend toward periodically assessing the impact of technology on academic performance and overall development, identifying risks such as distraction, declining results, and the loss of basic skills.
Tips for parents: How to encourage responsible use at home?
- Give exampleChildren imitate the behavior of adults. If parents regulate their own use, children will better understand the importance of limits.
- Plan usage schedules and alternatives: Establish clear routines, such as a “screen-free day” or device-free time slots.
- Don't use your smartphone or tablet as a distraction tool or to stop tantrums.. Promotes self-control and dialogue.
- Offers alternative leisure optionsBooks, board games, crafts, sports, and family time should be a priority.
- Monitor the choice of apps and games: Prioritize educational apps and restrict access to inappropriate content.
- Strengthen family dialogue about the risks and benefits of the digital worldListen to the concerns of young people and clarify questions about privacy, social distancing, and social media.
Benefits of a healthy and balanced use of screens
Responsible use of technology can offer benefits in learning and creativity., as long as the recommended time according to age is respected, quality applications are chosen, and they are implemented under adult supervision and guidance.
Some potential benefits include:
- Development of basic digital skills necessary for today's world.
- Stimulation of creativity through drawing, music or puzzle applications.
- Access to educational resources which can complement school learning if used in moderation.
- Strengthening family ties when parents and children share digital activities or explore new content together.
What NOT to do with digital devices in childhood?
- Don't use screens as a babysitter to calm, distract or “park” the child in times of stress or lack of time for adults.
- Do not allow indiscriminate access to YouTube, social networks, violent video games or apps without parental controls..
- Do not introduce screens into your daily sleep, eating, or hygiene routines..
- Do not give your own smartphones to very young children., preventing free and unsupervised access.
- Do not allow the use of devices in the bedroom, especially before sleeping..
Frequently asked questions and common doubts about the use of smartphones and tablets in children
- Is it necessary to completely ban screens? No, except for babies under 2 years old. The important thing is to adjust the time, use, and content to the age and context.
- Can they learn with educational apps and videos? Yes, but direct interaction and physical play are irreplaceable in the early years. Videos and apps should be a complement, not an alternative.
- Does occasional exposure cause harm? Occasional, supervised use within recommended limits does not cause harm, but repeated, daily, and uncontrolled exposure can negatively influence development.
- At what age can they start using social media? Most networks set the minimum age at 13-14. Before that age, it's advisable to limit access and always support digital learning.
The use of smartphones and tablets in childhood requires a informed, preventive and flexible lookScientific societies and international organizations agree on the importance of limiting time based on age, ensuring adult supervision, and prioritizing educational options, avoiding, as far as possible, indiscriminate access or using it as a substitute for play and family interaction. Applying these recommendations consistently and adapting them to the specific needs of each family is essential to protecting the health, learning, and emotional well-being of children, ensuring that technology is an ally, not a threat, to their overall development.
