Watching too many Reels maybe stressing your kid out, lead to attention problems: Report

A University of Bayreuth study has linked heavy short-video viewing among teenagers and young adults to inattention, impulsivity and stress. The findings point to risks from endless scrolling and personalised feeds, and support clearer screen-time routines.

In Short

• Study links heavy short-video use to stress and attention problems
• Researchers analysed data from nearly 47,000 young participants worldwide
• Experts recommend limiting screen time through structured digital habits

These days, social media is no longer just a place to share photos, chat with friends, or catch up on updates. It has evolved into a platform dominated by short-form videos and fast-moving, highly engaging Reels designed to grab attention within seconds. This trend hasn't left children behind either. Many kids today are hooked on short videos, and for some parents, getting them to eat without putting a phone in front of them has become a challenge.

But this habit may be doing more than just taking up time. According to new research, excessive viewing of short-form videos could affect how the brain focuses, controls impulses, and processes information.

Researchers have long warned about the growing problem of mobile addiction among children and teenagers. Now, a new study by researchers at the University of Bayreuth in Germany suggests that continuously watching short video clips may increase attention problems and stress levels among teenagers and young adults.

The study, published in June in the European Child & Adolescent Psychiatry journal, highlights the potential health risks associated with short-form videos, especially as more young people around the world spend hours consuming this type of content.

What did the researchers find?

According to the study, more than a quarter of TikTok users in 2023 were between the ages of 13 and 17, despite the platform's age restrictions. To understand the impact of short-form videos, researchers analysed data from more than 1,500 groups across 42 global studies conducted between 2015 and 2025. The analysis covered nearly 47,000 participants with an average age of 16.8 years and examined digital media use at home, in schools, and in youth gathering places.

The researchers found that the design of short-form video platforms plays a major role in keeping users engaged. The content changes every few seconds, constantly giving the brain something new to react to. While this may seem harmless, the study suggests that excessive consumption of Reels and similar videos can gradually affect the way the brain functions.

Why are short videos so addictive?

The study identified three key features that keep adolescents engaged: rapid content delivery, endless scrolling, and highly personalised algorithms. Researchers found that fast-paced content could harm future memory. Overly personalised feeds increased users' attachment to the content, while infinite scrolling encouraged longer screen time by reducing natural breaks between videos.

To better understand the neurological impact, researchers also included diagnostic assessments using EEG and MRI scans to measure brain activity.

How does heavy use affect mental health?

The researchers accounted for factors such as age, gender, country, cultural background, education level, and the platform being used. The results showed that heavy and unregulated use of short-form videos was linked to slight to moderate increases in inattention and impulsivity, poorer working memory, higher levels of anxiety, depression, and stress, as well as a noticeable rise in addictive behaviours.

The study defined "heavy use" as spending four or more hours a day watching short videos. "Unregulated use" referred to random, unscheduled viewing that interferes with sleep and daily routines.

What do researchers recommend?

To reduce these risks, the researchers recommended creating supportive social environments and setting clear schedules for digital media use. They believe these measures could help protect adolescents' behaviour and neurological development while encouraging healthier screen habits.
