New study reveals TikTok & Instagram content actually “rots” your brain

by

The way people watch videos online has changed dramatically with the rise of short-form content, and a recent report from the American Psychological Association suggests this shift is linked to worsening mental health.

This research analyzed data from nearly 98,000 people across 71 studies to understand how short-form video platforms like TikTok, Instagram Reels, and YouTube Shorts impact viewers of different ages.

Early studies focused mainly on TikTok. However, because short-form videos are now common on all major social media platforms, this research looked at the broader impact of these videos, rather than just focusing on one app.

This research looked at how people interact with fast-paced video content and how it relates to their thinking and well-being. The study also compared the experiences of young people and adults to see if age affects how they react to these types of videos.

Study finds TikTok & Instagram “rots” your brain

The report suggests that watching a lot of short-form videos may negatively impact brain function, specifically the ability to focus and control impulses. People of all ages who watched more of these videos tended to have shorter attention spans.

Researchers believe these patterns develop due to a process called habituation and sensitization, first described in 1970 by Groves and Thompson. Their work suggests that constantly watching fast-paced, exciting videos can make the brain less responsive to slower activities like reading or thinking through problems. Meanwhile, the way algorithms provide rewards may encourage quick reactions and immediate satisfaction.

According to the report, watching short-form videos activates the brain’s reward centers, potentially leading to addictive behavior. Spending too much time with this type of content is also linked to feeling more isolated, less satisfied with life, and experiencing problems with sleep, anxiety, and loneliness. Researchers note that further study is needed to understand the impact of these videos on how people feel about themselves and their bodies.

Scientists created a new tool to measure how addicted people might be to short-form videos, which will help with future research on this topic.

As a big follower of these short-form video platforms, I found the authors’ conclusion really interesting. They basically said that because these videos are everywhere now, it’s super important we figure out how they’re affecting our brains and how we act. Their research feels like a great starting point for even more studies on how these platforms are changing our everyday lives.

I was reading this interesting article, and apparently, it’s not just us humans who can get a little… fried from spending too much time online! They actually did a study showing that AI chatbots like ChatGPT can also start to show negative effects from constant use – it’s like they get a kind of ‘brain rot’ too! It’s wild to think about.
