On May 12, European Commission President Ursula von der Leyen publicly called for stronger protections against the “addictive designs” of social media platforms such as TikTok, raising concerns about their effects on minors.

The debate has expanded beyond screen time alone. Governments and health experts are increasingly questioning how social media algorithms shape the way teenagers perceive and understand topics such as health, nutrition, and mental illness. 

Earlier this year, the European Commission announced preliminary findings against TikTok under the European Union’s Digital Services Act (DSA). 

Regulators argued that features such as autoplay, endless scrolling, and personalized recommendation systems could pose risks to minors. 

According to the Commission, the platform’s design may contribute to addictive behavior among young users.

At the same time, health misinformation spreading through short-form videos has become an increasing global concern. 

Videos promoting rapid weight-loss methods, “gut health hacks,” ADHD self-diagnosis, and unverified skincare treatments often garner millions of views within hours.

Unlike traditional medical sources, many of these videos are presented in a highly personal and relatable format.

Influencers often speak in casual and highly personalized ways that are easier for teenagers to relate to. 

Several students interviewed for this article said they often encounter health information on TikTok before hearing about it from medical professionals or official health websites. 

“If I suddenly have a skin problem or trouble sleeping, I usually search TikTok first because the videos are shorter and easier to understand,” explained one high school student in Seoul.

Another student expressed that TikTok feels “less intimidating” than medical websites.

“Doctors use difficult words sometimes, but TikTok creators explain things quickly in ways that feel more personal,” she said.

Researchers say the trend reflects how trust is changing in digital spaces. 

Online, people often trust information not only because of expertise, but because content feels familiar, repeated, and easy to relate to. 

As users repeatedly encounter similar content through personalized feeds, information can begin to feel trustworthy simply because it is frequently shown.

This phenomenon has raised concerns among policymakers regarding the role social media companies should play in protecting adolescents online.

Reuters reported that several European countries are considering stricter youth protection policies. 

Proposed measures include age verification systems and restrictions on addictive platform features targeting minors. 

The debate now centers on whether platforms like TikTok simply host content or actively shape user behavior through algorithms. 

Experts caution that emotional or dramatic health claims tend to spread especially quickly on short-form platforms, often faster than cautious medical explanations. 

The issue is particularly concerning for teenagers, who spend significant time online while still forming habits and self-image. 

Many students interviewed said they were aware that misinformation exists online. However, they also admitted that fast, visually engaging videos are difficult to ignore, especially during stressful academic periods.

“It’s easier to watch a 30-second TikTok than read a long medical article after school,” one student explained.

The debate surrounding TikTok transends mere screen time or social media trends. 

Instead, it is increasingly focusing on how young people find information and who they trust online. 

As governments continue discussing youth protection and algorithm regulation, platforms like TikTok may face growing pressure to take responsibility for the health information spread on their platforms.
