Algorithms and Children’s Mental Health: How Schools and Parents Navigate Digital Worlds

The digital environment in which children grow up today is shaped by invisible forces – social media algorithms. These systems, designed to maximize user engagement, have a profound and often unsettling impact on young people's mental health. In recent years, they have become the subject of intense debate as increasingly clear evidence emerges of their influence on anxiety, depression, and even addiction.

The Hidden Power of Algorithms and Their Impact

Algorithms act as content curators, determining what appears in a user's feed based on previous interactions. If a child repeatedly views content on a particular topic, the algorithm will offer similar material, which can lead to cycles of endless scrolling and potentially harmful exposure. Studies show that adolescents who spend more than three hours per day on social media face a significantly higher risk of mental health issues, including increased symptoms of anxiety and depression. Those who spend five to seven hours even have double the risk.

The problem is exacerbated by the fact that up to 95% of young people aged 13-17 use social media, with almost 40% of children aged 8-12 also online. On average, US teenagers spend nearly 5 hours daily on social media. Platforms like TikTok, Instagram, or YouTube often expose young users to unrealistic ideals, negative news, or even content promoting self-harm or eating disorders.

Case Study: TikTok Algorithms and Their Dark Side

A well-known investigation by The Wall Street Journal revealed how algorithms can lead to dangerous spirals. As part of an experiment, over 100 automated accounts were created, and it was found that once the algorithm recognized certain interests, it consistently offered disturbing content. Some accounts were repeatedly exposed to videos promoting eating disorders, sexualizing minors, or romanticizing suicide and depression. This example clearly illustrates how systems designed for engagement can unintentionally, but with serious consequences, escalate exposure to harmful content.

Regulation and Transparency: New Challenges for Platforms

Global governments and regulators are recognizing the severity of the situation and tightening rules. The European Union is at the forefront with the Digital Services Act (DSA), which is currently in full enforcement mode regarding child protection online. Investigations are underway against platforms like TikTok and Snapchat due to algorithmic risks to minors and addictive design. The European Commission is even considering a bloc-wide ban on social media for children under 13 and introducing stricter controls for older children.

In the US, the Federal Trade Commission (FTC) is focusing on protecting children online, and some states, such as California and Maryland, are implementing their own age-appropriate design codes. In May 2026, the TAKE IT DOWN Act also came into force, establishing civil liability for platforms that fail to remove non-consensual intimate imagery, including AI-generated content.

The Role of Schools and Parents: Equipping Children for the Digital World

With increasing risks, it is crucial for parents and schools to actively engage in equipping children with the skills to navigate online safely. UNICEF, in its 2025 report, emphasizes that solutions should focus on preventing online abuse and bullying and reducing exposure to harmful content, rather than merely restricting screen time.

Media Literacy: Integrating media literacy into school curricula is fundamental. Children need to understand how algorithms work, how data is collected, and the impact of algorithmic bias. Teaching critical thinking, recognizing misinformation, and ethical online behavior should be part of education from an early age.

Active Parenting: Parents should actively educate their children, set screen time limits, use parental controls, and promote positive online behavior. Open conversations about what children see and experience online are also important.

Checklist for Parents and Educators: Navigating Algorithmic Risks

For effective child protection in the digital world, I recommend focusing on these areas:

• Algorithm Education: Explain to children that content isn't random but is selected by a system. Discuss how algorithms learn from their behavior. (See the onesafety project at one-o-one.cz, which focuses on digital literacy.)
• Critical Thinking: Teach children to question content. Who created it? What is its purpose? Is it realistic?
• Digital Detox and Limits: Set clear rules for online time and content types. Encourage offline activities.
• Open Communication: Create a safe environment where children are not afraid to talk about unpleasant online experiences.
• Privacy Protection: Teach children how to protect their personal data and how to set privacy settings on platforms.
• Addiction Recognition: Monitor for signs of excessive use and seek professional help if addictive behaviors emerge.

The Future of Digital Safety

The path to a digital environment that is safe and supportive of children's mental health is complex. It requires the cooperation of technology companies, governments, schools, and families. Platforms must take greater responsibility for the ethical design and transparency of algorithms. Our role as adults is to equip children with the tools and skills to become conscious and resilient digital citizens. The goal is not to ban technology but to learn to live with it healthily and with critical discernment.

FAQ

Q: What is the main impact of algorithms on children's mental health? A: The main impact is the amplification of anxiety, depression, low self-esteem, and the development of addictions. Algorithms optimize content for maximum engagement, which can lead to endless scrolling and exposure to harmful or unrealistic content that negatively affects children's psyche.

Q: What is the Digital Services Act (DSA) and how does it protect children? A: The Digital Services Act (DSA) is an European Union regulation that imposes obligations on large online platforms regarding algorithmic transparency, content moderation, and the protection of minors. Its goal is to reduce the spread of harmful content and limit addictive design elements that threaten children's mental health.

Q: How can parents support their children's media literacy? A: Parents can support children's media literacy through open communication about online experiences, teaching critical thinking about content, setting clear limits for online time, and using parental controls. It is also important to explain to children how algorithms work and why they see certain content.
