The Impact of TikTok on Youth

The Impact of TikTok on Youth: A Critical Analysis

Concerns have been mounting regarding the influence of TikTok on the mental health and attention spans of children and adolescents. Coined as “TikTok brain” by Julie Jargon in The Wall Street Journal, this phenomenon highlights the challenges young individuals face when transitioning from binge-watching short-form content on platforms like TikTok and Instagram Reels to activities that do not offer instant gratification.

Understanding the Dopamine Effect

The addictive nature of TikTok is closely tied to the release of dopamine in the brain. Cincinnati Children’s Hospital’s pediatrician and Reading & Literacy Discovery Center director, John Hutton, aptly describes TikTok as a “dopamine machine.” Dopamine, a neurotransmitter, surges when the brain anticipates a reward, reinforcing cravings for pleasurable activities, be it a delicious meal, a drug, or a humorous TikTok video.

The Dopamine Cycle

Neuropsychologist Dr. Sanam Hafeez explains that laughter triggered by TikTok content results in a dopamine rush. If a user encounters something unappealing, they can swiftly shift to content that promises a greater dopamine boost. This repetitive cycle can potentially condition the brain to yearn for the quick rewards associated with shorter content.

Exploring the Impact

While research on TikTok’s specific impact on the brain is still in its nascent stages, scientists are increasingly intrigued by this area. A study conducted by Guizhou University of Finance and Economics in China and Western Michigan University suggests that TikTok and similar YouTube Shorts engage users through “short bursts of thrills,” possibly contributing to addictive behavior.

Collective Attention Span

Moreover, a 2019 study published in Nature Communication, as cited by the Science Times, hints at a narrowing “collective attention span” due to the rapid consumption of social media content. While this study did not exclusively focus on TikTok, it suggests that the app may indeed affect individuals’ cognitive processes.

The Vulnerability of Youth

Children and teenagers are particularly vulnerable to these effects because activities requiring sustained focus, such as reading, rely on “directed attention,” a function regulated by the prefrontal cortex. This critical brain region, responsible for decision-making and impulse control, does not fully mature until around age 25.

Constantly Changing Environments

Michael Manos, Clinical Director of the Center for Attention and Learning at Cleveland Clinic Children’s, highlights that the ever-evolving landscape of TikTok does not demand sustained attention. Consequently, this makes it challenging for young brains to adapt to non-digital activities characterized by a slower pace.

Cultural Conditioning

Gloria Mark, author of “Attention Span: A Groundbreaking Way to Restore Balance, Happiness, and Productivity,” argues that cultural indoctrination encourages young individuals to favor highly stimulating, rapid scene shifts, making it increasingly difficult for them to engage in activities that do not offer instant gratification.

Addressing Overuse

Social media companies are taking steps to combat potential overuse by younger users. TikTok, for instance, restricts push notifications after 9 p.m. for users aged 13 to 15 and periodically reminds users to take breaks.

YouTube’s Response

YouTube has introduced YouTube Shorts, featuring content not exceeding 60 seconds, and implemented features such as disabling autoplay and sending reminders to take breaks or get enough sleep for users aged 13 to 17. YouTube spokeswoman Ivy Choi affirms that the company closely monitors research outcomes and collaborates with third-party experts to enhance the Shorts experience for young people and their families.


As awareness of the potential effects of ‘TikTok brain’ continues to grow, it is paramount for parents to encourage balanced technology usage among their children. While social media companies are making strides to address these concerns, the ultimate responsibility rests with parents to safeguard the well-being of their children in this digital age.
