What Staring At A Screen All Day Is Doing To Your Brain And Body | The Human Body

Americans spend more than seven hours a day starting at digital screens. This screen time often leads to blurred vision, eyestrain, and long-term vision problems like nearsightedness. What’s more, screens emit blue light, which disrupts our circadian rhythms at night when we’re trying to fall asleep. And all of this screen time might even change our brains. A new and ongoing study supported by the NIH found that some pre-teens who clocked over seven hours a day on screens had differences in parts of their brains compared to kids who spent less time on screens.
Following is a transcript of the video:
It’s 11:00 pm. You should be asleep. But you’re watching a video on your phone. Tomorrow, you’ll wake up and go to work, where you’ll stare at your computer for 8 hours. When you get home, you’ll watch a movie on TV. And if you’re anything like the average American adult, you spend more than 7 hours a day staring at digital screens.
So, what’s all this screen time actually doing to your body and brain? Humans didn’t evolve to stare at bright screens all day. And our eyes are suffering the consequences. An estimated 58% of people who work on computers experience what’s called Computer Vision Syndrome. It’s a series of symptoms that include:
- eyestrain
- blurred vision
- headaches
- and neck and back pain
And long-term, this amount of screen time could be damaging our vision permanently. Since 1971, cases of nearsightedness in the US have nearly doubled, which some scientists partly link to increased screen time. And in Asia today, nearly 90 percent of teens and adults are nearsighted. But it’s not just the brightness of our screens that affects us. It’s also the color. Screens emit a mix of red, green, and blue light - similar colors in sunlight. And over millennia, it was blue wavelengths in sunlight that helped us keep our circadian rhythms in sync with our environment. But since our circadian rhythms are more sensitive to blue light than any others,
A problem occurs when we use our screens at night. Typically, when the sun sets, we produce the hormone melatonin. This hormone regulates our circadian rhythms, helping us feel tired and fall asleep. But many studies have found that blue light from screens can disrupt this process.
For example, in one small study, participants who spent 4 hours reading e-books before bed for 5 nights produced 55% less melatonin than participants who read print books. What’s more, the e-book readers reported that they:
- Were more alert before bed
- Took longer to fall asleep and reach a restorative REM state
- And were more tired the next morning
But perhaps the most concerning changes we’re starting to see from all this screen time is in kids’ brains. An ongoing study supported by the NIH has found that some pre-teens who clocked over 7 hours a day on screens had differences in a part of their brains called the cortex. That’s the region responsible for processing information from our five senses.
Usually, our cortex gets thinner as we mature. But these kids had thinner cortices earlier than other kids who spent less time on screens. Scientists aren’t sure what this could mean for how the kids learn and behave later in life. But the same data also showed that kids who spent more than 2 hours a day on screens scored lower on thinking and language skill tests.
To be clear, the NIH data can’t confirm if more time spent staring at screens causes these effects. But they’ll have a better idea of any links as they continue to follow and study these kids over the next decade. It’s no doubt that screens have changed the way we communicate. But only time will tell what other changes are on the horizon for humankind.

[@rkbelmont1138]

I am a software engineer so I spend lots of time at the screen, and eyestrain is a real problem. Here is the trick when you are at a computer. Every 20-25 minutes, stand up, stretch a little, and stare at a distant point. It can be anything, you must stare to a point at least 4m away, to give your eyes a rest. This should last 1-2 minutes. Also, at max every 2 hours, get out of wherever you are and walk around. Get some fresh air, etc. I apply this and I feel my eyes much better. Also, stay away from any digital screen for one hour before you go to bed. There are plenty of nice night routines you can follow. If you can avoid having a TV on your bedroom, better.

computers screens can definitely cause eye strain, but it's tricky to associate them as the cause for nearsightedness. It could also be that sitting in front of a computer all day can simply hold you from activities that promote healthy eye development, like exercising and getting some sun. Same with the kids, is the computer screens the cause of their cortex thinning, or is it just a correlation?

I get a lot less headaches now that I have a “blue-blocker” coating on my glasses lenses. I also keep my night mode / blue blocker setting on my phone and computer on 24 / 7. When you first turn it on, it looks very orange, but your brain adjusts very quickly. I highly recommend it.

[@ellaneruda]

laura lee’s nonexistent tears oof Do you have an iPhone or Android?

[@tatip9881]

Ella Neruda iPhone

[@ellaneruda]

laura lee’s nonexistent tears oof Go to the iPhone settings and search “night shift”. If you want it on 24/7 like I do, turn on scheduled, and set it from 6:01am - 6 am or whatever hour you want (eg 7:01am - 7 am, etc). You will have one minute where the screen is blue, but that is not a big deal. You can choose how “warm” you want your screen to be. I keep mine at 50%. It looks super orange when you first change it, but your eyes will adjust very, very quickly. In my opinion, the only reason to turn it off, would be if you were online shopping for clothing or paint, and you wanted to make sure it was EXACTLY the right color. Hope that helps! Let me know if you need clarification :)

I complete watching this video at 2:16 am. And now I guess my life is fucked, specially when the narrator says "it's 11:00 pm you should be asleep." 😖

[@piletpig124]

Don’t worry. I play smash bros ultimate at 3-5 PM at night every 2 weeks.

Watched this video half way to save my eyes. Thanks for the tips

[@MadDragon75]

I'm constantly doing independent research. I found that reduced brightness and listening rather than watching reduces eye strain and headaches.

"being alert before bed" might be right but it doesn't mean having difficulty at sleeping. It feels good as if having accomplished something. After waking up from 2-3 hours sleep, the human gets strange insane energy, but foggy-chaotic minded.

Great video. Any chance you add Spanish captions? I would like to show this video in the daily safety briefing at work. Thank you

[@Nsamity]

Didn’t they stare at a screen while making this? 🤔

[@tedros6917]

the increase in nearsightedness may not be due to screen time. studies are beginning to lean towards the possibility that it's being caused by reduced sun exposure, which would explain why china has a disproportionate amount of nearsighted young people - since they spend incredibly long periods of time studying indoors as compared to other countries. I would assume time indoors and increased screen time have a very strong correlation, therefore it would be difficult o discern which element is the actual trigger

[@SuccessforLifester]

I put my handphone down and just listen to the audio from this video as it plays
