Study Reveals Tiktok, YT Shorts, IG Reels Actually Rots Your Brain For Real

[RAMROD 117,004]

 

Short-form video has reshaped how people consume content online, and a new report from the American Psychological Association now directly connects that format with notable declines in mental health.

The study draws on data from 98,299 participants across 71 separate papers to examine how TikTok, Instagram Reels, YouTube Shorts, and similar platforms affect viewers across different age groups.

Not surprised by this whatsoever. One of the reasons I still do not have a Tik tok and limit the amount of time I spend looking at IG reels.

This was already obvious just looking around at the members of our society

I honestly can feel it when I over consume social media. 
I just started a social media weekend long detox because I got too anxious and can’t function well

Unexpected

That's why I don't have TikTok or Instagram

Indeed... I only use Instagram, but I've noticed all those patterns in my own behavior. I'm of an obsessive and impatient nature to begin with so it's definitely not helping and I find watching films without interruption and reading are good solutions to counter those habits.

Short-form video has reshaped how people consume content online, and a new report from the American Psychological Association now directly connects that format with notable declines in mental health.

The study draws on data from 98,299 participants across 71 separate papers to examine how TikTok, Instagram Reels, YouTube Shorts, and similar platforms affect viewers across different age groups.
 

The study analyzes user engagement patterns and assesses a range of cognitive and mental health indicators. Researchers also compared outcomes between youths and adults to better understand how different age groups respond to rapid-fire video feeds.

According to the report, heavy short-form video consumption is linked to diminished cognitive function, particularly attention control and inhibitory control. Both younger and older participants who consumed higher volumes of short videos showed poorer attention spans overall.

To explain how these patterns form, researchers point to the dual theory of habituation and sensitization from Groves and Thompson’s 1970 work on cognitive processing. The study notes that constant exposure to fast, highly stimulating clips can desensitize the brain to slower tasks like reading or problem solving. At the same time, algorithmically delivered rewards may reinforce impulsive engagement and instant gratification.

The report says this form of consumption stimulates the brain’s reward system and can encourage habitual use. Excessive short-form video viewing is also associated with social isolation, lower life satisfaction, poorer sleep, increased anxiety, and loneliness. The authors add that more work is needed on how this content affects self-esteem and body image.

Researchers also developed an assessment scale for short-form video addiction, designed to help future studies measure dependency on these platforms.

The authors conclude that short-form videos’ widespread presence makes it critical to understand their impact on cognitive health and behavior. They note that the findings establish a foundation for future research into how these platforms influence daily life.

In news: water is wet. This is why I stopped teaching... kids were becoming monsters addicted to their phones and the parents only said "it's their comfort object". No lie, I once had a parent tell me I can't tell a student to put his laptop away because it is his security blanket. I was then called heartless for trying to make this same point to parents/my boss and told I wasn't getting with the times. In the US- we have Trump because the growing stupidity of people got played to and those individuals had no cognitive capacity to actually spend time researching/analyzing credible footage (debates, news, etc.).  I remain on an education board but refuse to go back to teaching until there is a ban on mobile devices in the classroom and they stop making everything virtual because kids cannot be trusted to go on their computers and focus or multi-task. 

Being able to walk away from social media and carry on with life when needed is an essential skill and its lost... and frankly because the parents now are rotting their brains the same way/passing it on. I think social media is fun but you have to regulate yourself or just be able to walk away and actually live life.

That rot in your brain is real how dumb do u want me for real 

[CautiousLurker 19,709]

Can someone who bothered reading the study let me know how they link the impact to the emergence of reels specifically, and not life in general getting sh*ttier by the year 
Like, yeah, reels are popular, but average length of youtube videos grew also, especially with video essay format becoming THE thing it's not uncommon for videos to tip over 2, sometimes 3 hour mark, and at least some people say they find that more appealing than your average movie...

Idk... I've noticed such a sharp decline in quality of produce combined with frankly ludicrous raise in prices... working conditions dicreased - employers seem adamant to squeeze as much as they can out of their employees because 'growth', a lot of people have to work more on top of that in order to be able to afford necessities - that's gonna hit you with lower life satisfaction, poorer sleep, increased anxiety, and loneliness also, probably more so than reels

Everybody's addicted to it and it's super normalized. Social media / tiktok is the 2020's cigarette

Where I'm from the government banned cellphones in schools this year. The students protested because they said they needed their phones for emotional support. I understand that they are indeed used that way, but we have gotten way to comfortable with the idea that it is normal

I think we all already knew this but glad someone said it

ADD is becoming so common and people are becoming less social in real life...

I feel sorry for all these iPad babies especially. It’s all they know.

Parents don’t actually want to PARENT these days. 

Such a disgraceful society.

Wbk, this app should be banned, it's really dangerous and full of false information that people eat up without questionning anything.
