How Digital Habits Are Weakening Your Brain and Ways to Rebuild Focus

So, there's a habit that almost all of us do every single day, and it's quietly weakening your brain. I'm talking about

the parts that determine whether you feel sharp or foggy, decisive or scattered, motivated or completely

stuck. I'm talking about your cognitive capacity. Today, I'm going to show you exactly what that habit is, what it's

doing to your brain, and how to start reversing it. And as always, I'm going to try to be as efficient and concise as

possible with this, but I also want to be very thorough. So, I really respect your time. I might be moving quickly. I

say that because I really think you need to hear all this and you really should stay for the whole video, but also I'm

not going to run this out into a 25-minute video when it can be done in 10 minutes. So, if you have felt more

distracted lately, more mentally tired, more overwhelmed by simple tasks, you're not just imagining it. This likely isn't

just aging like some people will think. It's not a character flaw. It's not that you're just bad at focusing. New

research is showing that common patterns of digital behavior, aka doom scrolling, app hopping, endless short form content,

mindless morning phone use. These are all linked to measurable hits to your attention, your executive function, your

working memory, and your self-control. We all had our parents yell at us to get off of our phones and they said it was

going to rot our brains. Well, they might have been right. We are seeing significant deficits across multiple

studies. And I want to be very clear, this doesn't mean that you're getting dumber. It means that your brain is

being trained in the wrong direction. The problem isn't just screens to a degree. It's how you're using these

screens. It's the micro switching. You hear me talk a lot about the negative impacts of multitasking. And that's what

you're constantly doing on your phone. It's the constant novelty. It's that dopamine drip of tiny unintentional

scrolls again and again and again with drastic emotional swings in almost every single one. One recent study on short

form video found that scroll immersion, which is that feeling of like falling into your feed, like you just really

fall into it, strongly predicted attention problems, working memory disruptions, and cognitive fatigue.

Another study using EEG found that people with high short form video addiction tendencies had weaker frontal

theta power during tasks that required executive control and lower self-control scores overall. In simple terms, the

more your brain gets trained on rapid novelty, the less capacity it has for deep thinking. The best way I can

summarize this is you're teaching your brain to crave stimulation instead of focus. And if you've been feeling that

in your own life, that constant mental buzzing or just detachment from reality or that inability to stay on one thing,

this might be why. To really drive home the point about the impact of this and something that really isn't even talked

about enough in the studies, but when you're constantly just feeding your brain that stimulation, you distancing

yourself from the present, distances yourself from purpose. And I want to make something really clear that you

hear me say in a lot of videos. You are going to die eventually. Do not waste this wonderful life and opportunity that

you have scrolling it away because you are addicted to that dopamine buzz. It may be hard, but I'm going to give you

steps very soon in this video on how to fix this. I'm telling you, chase after a beautiful purpose, not scrolls. And

you'll hear me mentioning different studies in this video. I'm going to link them in the description for you. So, I

want to talk about the science to this. And in my usual fashion, let's break this down in simple human terms. Number

one, attention. Some of the biggest deficits across the research are in attention, which is what I talk about so

much on this channel. Where your attention goes makes a drastic difference in your life. I cannot

exaggerate that enough. People with disordered screen time use patterns perform significantly worse on

focusbased tasks. You might resonate with this with the feeling of like I just can't get into things anymore or I

just can't stay on task these days. Like that type of person who's like oh I can't focus anymore. That could be where

this is coming from. Number two, your executive function also takes a hit. This is your ability to plan, inhibit

impulses, which is equally as important. Switch tasks intentionally and stay on track with things. This is why you may

sit down to reply to one email and suddenly you're on Tik Tok, Instagram, or shopping on Amazon without even

realizing it. Number three, cognitive flexibility and decision-making. Big cohort studies show that heavy

smartphone use with media multitasking. So, the things we've been talking about are linked with increased impulsivity,

cognitive inflexibility, and worse decisionmaking. You become more reactive. Simply put, you become more

jumpy and you get overwhelmed by simple choices. You're not less intelligent, per se, at least there haven't been many

studies that have really measured IQ in this setting, but you're just running on a brain that is overstimulated and

undertrained. And if you don't think this is important, think about how many decisions you make in your life and how

one single decision can drastically alter your day, your week, your year, your life. You want to be good at that.

Don't weaken it for some shallow reason. And I know this might sound real and intense, but it's really important. I'm

telling you, I just I see so many people literally on their deathbed. I'm in a very unique opportunity as a physician.

And so many of these people will tell you that they just never really lived or really realized why they were here. And

I don't want that to be you. And I think this is a big part that is in the way of that. So, let's keep going. And again,

I'm going to move fast because I really do respect your time, but you do need to hear the rest of this. These impacts

weren't just showing on performance test. Brain imaging studies showed consistent gray matter reductions in the

dorsolateral preffrontal cortex. That's a tough one to say, and anterior singulate cortex. These are the regions

responsible for top-down control, focus, and emotional regulation. These are also responsible for decisionm and these were

all seen in people with problematic internet patterns. A large longitudinal study showed that high internet use

predicted smaller gains in verbal intelligence and smaller increases in gray and white matter in the areas

responsible for attention, language, and executive function over several years. Again, this is not a fear-mongering for

views type channel. This is the exact opposite of that. And I want to be really clear. This isn't like brain

damage like you would think about it in common terms. Like that's not what I'm going to make the title of this video

for clickbait reasons like a lot of people might. And I'm saying this because I want you to know that it's

reversible. This difference though is meaningful enough to change how you feel. And that matters to a profound

degree. You know, so much of why I started this channel is because I feel like for so many years the focus was

just simply on keeping people alive. But we let go of how people actually lived. So we've got people living a decent

amount of time, but many people are just skeletons of what they could be. And I don't want that for you. I've seen this

in so many people. I've seen this in myself at times. Before medical school, and also partly in medical school, as

well as during the early stages of building multiple businesses, my attention was shredded. I wasn't

depressed. I wasn't lazy by any means. My cognitive capacity had just shrunk to a point where I struggled to function at

a high level. Admittedly, that might have made me a little bit depressed in hindsight. Once I fixed this underlying

behavior, though, everything changed. So, how do we know if this is already happening to you? Let's do a quick test.

Let's call it the put a finger down version. You know, if three or more of these hit, you're probably dealing with

this issue. And this is just a fun little game. So, if any of these really resonate, you should probably focus on

it. You can't read more than one to two pages without reaching for your phone. You lose your train of thought mids

sentence. You open your phone for one thing and do five other things instead. You feel mentally tired after tasks that

should be easy. You bounce between tabs with no plan. You feel mentally cluttered most of the day. If that's

you, it's not too late. Your brain is insanely adaptive. Let's talk about how to rebuild it. Now, if you stayed for

this part, drop a comment right now to know that your attention span is better than the vast majority of the population

because we are a few minutes into this and I'm very proud of you, but you really do need to hear this part. Let's

dive into it. This is the practical steps that you need to do. These are the same tools that I've used on myself, my

patients, and clients have used. And honestly, this is the foundation of what I teach inside my new community that is

loaded with resources to start living your best life. You should really check it out. I'll link in the top of

description. The best thing is these things work incredibly well. So, you need to do reps like you're in the gym

of deep work. Forget the idea though that you should sit down and study or do something for 3 hours like this monk

mode type focus. That is not where you start. You start with 10 to 30 minute deep work reps. One task, no switching,

no notifications. Consider this like interval training. At first, you may feel incredibly dependent on these

structured blocks, like you're really not going to get a lot done if you're not using them. That's normal. That

doesn't mean that your brain is broken. It means that your brain hasn't been trained for depth in a long time. But

here's the part that I feel like a lot of people don't talk about and slash or realize. The more of these reps that you

do, aka the more times you dive into these deep work sessions, whether that's 10 minutes or 30 minutes or 40 minutes,

and then by the way, you're going to take a 10-minute break. And then if you need to do more work, then you do

another block like that. And then you take another break. And you have to combine that with the less stress that

your brain is also taking from social media and these triggers that we've been talking about, the less you'll rely on

the structure at all. So to really simplify this, you need to do the good things and you need to take out the bad

things. Okay? So more of the reps, less of the stressors. Your brain gets stronger, focus becomes much easier, and

eventually this becomes your baseline. That's the goal. What I'm saying is the more you do this, the less you will

depend on it in the future. And that's huge. I started a timer every time I worked when I first started on this

journey. When I was in medical school, I would get my timer and just set it for a 30 or 40 minute block and then 10-minute

break and I was back to doing it again or I'd be time blocking or something like that. Now, I don't ever do that. I

had a hard a physical timer. I don't even know where it is. I trained my focus. You learn to be able to focus for

very long periods of time when you practice this. Like I said, you can stretch this to 30 minute blocks or 45.

You can keep pushing it, but after about that time frame, I wouldn't avoid breaks. Like 45 to 60 minutes is

probably your max. Then you should take a short break. This is also called the pomodoro technique. By the way, lots of

free timers in app stores and the internet. Like you can literally just pull up a web page and you can do a

pomodoro timer. It's super easy. Next dual in back. Okay, this is like working memory strength training. This is your

mental weights. Duel and back is one of the only cognitive training methods shown in research to reliably improve

working memory. This underlies your focus, your problem solving, your decision-m and your emotional

regulation. 15 to 20 minutes daily or almost every day. You will hate it at first. It sucks. I'm sorry. It's about

the only thing that I consistently talk about across this channel that just isn't fun to do. But you will feel the

results everywhere. Your mind gets quieter. Your thoughts get much sharper. And most importantly, you feel more

mentally capable. The feelings are subtle at first, but stay with it and you will build yourself into an absolute

powerhouse. Now, no scroll mornings and no scrolling before deep work. This one is huge. Your morning sets your tone for

the entire day. If the first thing that you do is to give your attention away, your brain spends the rest of the day

trying to get it back. So, here's the rule. And before a deep work block, no scrolling or no short form content

before then either. No phone, no feed, no digital novelty like we talked about earlier. Let your mind settle, get your

baseline back, then start. This alone can change your cognitive capacity almost anything else. And no, I know

these things aren't flashy. This isn't like the super hype study channels that people love to listen to, which I think

are really good, by the way. These are just different techniques, but this is building your core foundation. None of

that stuff will make a big difference if you don't have your foundation down. Trust me on these things. Just do them.

Now, when it comes to limiting your impulses to be able to do this kind of doom scrolling, I recommend

friction-causing devices like Brick or there's some other brands out there to interrupt that reflex to scroll. Now,

you hear me say the words we want to reduce friction so often on this channel. Well, let's build up some

friction to the stuff that we don't want to do here. So, this is the opposite, but this is we're building friction to a

negative trait. Look, we all override the app blockers. We all cheat on our screen time limits. We are human. They

don't work for most people. I'm sorry. That's why devices like Brick exist. These are physical NFC tags that you

tap, it locks down the apps, and they can't be overwritten. I mean, how much more simple and effective could that be?

You tap your phone on the tag, stick it on the fridge in a different room, and it locks the apps that you've chosen to

lock. There are plenty of brands for this. Brick is the one that I like. I will put my affiliate link in the

description. I will also put a non-affiliate link in the description. It's your choice. I'm not sponsored. I

don't know them. I just like their product a lot. I wouldn't mention it if it didn't work. It's helped a ton of

people break the unconscious reflex that kills cognition. If you don't think that you have this unconscious reflex, look

at your screen time. Now, attention recovery windows. At least one or two 30 to 60 minute blocks a day where you

don't scroll, you don't multitask, you don't stimulate your brain, you let your nervous system settle. This resets this

cognitive fatigue that we're in constantly. It restores stability and it literally reensitizes your attention.

This is where you start to feel like your old self again is what people will tell me. Go for a walk, read a book, sit

there, call a friend, and have a joyful conversation, not drama. You get the point. So, wrapping it up, here's the

truth. You don't have a motivation problem. You have an overstimulation problem. And an overstimulation problem

is reversible. Your cognitive capacity is not gone. It just hasn't been trained in the right direction. If this video

hits, if it feels like the missing piece for you, my community is where we're going deeper into this work. It is a

space for people who want clarity, strength, and mental performance without the chaos. It's full of life-changing

content that I update all the time, like almost daily. direct access to chatting with me and asking me questions,

protocols for many areas of life and performance and accountability with a community if you want that. I think it

can change your life and I would love to see you inside. And if you want the deeper blueprint for this without the

community aspect, everything I used to rebuild my own mind, it is exactly what I wrote in my book from Dole to Doctor.

It is in all forms. I'll link in the description. Check it out. I wrote this because it is the guide step by step

that I wish I had when I was going through this like you may be now. It is sciencebacked, but it is also written

like a knowledgeable friend is talking to you. And I think you might enjoy that. For now, here is your 7-day

challenge. Every morning, no scrolling for the first hour. Every day, one 10 to 30 minute deep work session. Every other

day, 10 to 15 minutes of duel and back. Do that for a week. Your brain will feel different. I promise. if this resonated

with you. Please like this video and subscribe. Also, turn on your notifications so you don't miss another

amazing video like this. I drop one to two of these a week. Also, hype the video. It's a new feature and it seems

pretty amazing and it helps the channel grow so I can keep doing this for you. Share this video with someone that you

think it could help. It's completely free and it is the least that you can do to help a loved one. Now, great job

getting this far. As always, I'm Dr. Matt Jones. Thanks for watching. I'll see you in the next one.
