00:00Did you know that Brazilians spend, on average, more than 9 hours a day connected to the internet?
00:06It's almost half the day spent with our eyes and a screen.
00:09But what is this actually doing to our brains?
00:12Today, you will discover how the digital world is changing the way we think and feel.
00:18and even how we remember things.
00:20Get ready, because the revolution isn't happening out there, but inside your head.
00:26If we look at the data, the reality is shocking.
00:30Brazil stands out as one of the most connected countries in the world.
00:33We are champions in screen time, dedicating hours and hours a day to social media, such as
00:38TikTok, Instagram, and YouTube.
00:41These platforms are not just a pastime; they have become an extension of who we are.
00:47It's as if our lives happen in two parallel realities, the physical and the digital.
00:54And increasingly, digital technology seems to be winning the battle for our attention.
01:01The internet has become our mirror, and we have become hostages to the attention it gives us.
01:07Give it back.
01:08Each post, each story, each video is a piece of ourselves that we throw into the digital universe.
01:14Waiting for a response, a validation, a connection.
01:19But at what cost?
01:20To understand the power these platforms have over us, we need to talk about a molecule.
01:27powerful.
01:28Dopamine, in simple terms, is released every time you receive a like or a comment.
01:34or even a simple notification, your brain releases a small dose of dopamine,
01:41the famous reward hormone.
01:43It's the same substance released when we eat something delicious or achieve a goal.
01:50The problem?
01:51Our brains don't differentiate very well between the origins of this pleasure.
01:56For him, the pleasure of seeing a new notification is chemically similar to other sources.
02:02satisfaction.
02:03With each scroll, a dose of pleasure.
02:06And the more dopamine the brain receives, the more it wants to repeat the cycle.
02:11This creates an addictive loop.
02:14The side effects are already known to many.
02:17Constant anxiety, an inexplicable loss of focus, and that feeling of urgency.
02:24that prevents us from relaxing.
02:26We are always waiting for the next stimulus, the next notification, the next dose.
02:35With this flood of stimuli, we were led to believe in a modern superpower: multitasking.
02:43The ability to do several things at the same time.
02:46Replying to WhatsApp messages while watching a YouTube video.
02:51Listen to music and supposedly work on a spreadsheet.
02:55It seems efficient, doesn't it?
02:57But the truth is that the human brain wasn't designed for that.
03:02We are not computers with multiple processors.
03:07When we try to do several things at the same time, we are actually just switching between them.
03:14Complete the task quickly.
03:16Spending mental energy with each exchange.
03:18The practical result is the opposite of what we want.
03:21Productivity drops, mental fatigue increases, and we start forgetting simple things.
03:28The internet promised us speed, but in return, it seems to have taken away our ability.
03:34to focus on one thing at a time.
03:39And it's not just our attention that's changing.
03:41The way we think and store memories is also being reconfigured.
03:46Think about it, when was the last time you made an effort to memorize a number?
03:52Phone or the way to a new place?
03:55Today, we have what scientists call the Google effect.
04:00We no longer worry about memorizing the information itself, but rather about remembering where it is located.
04:05We can find it.
04:07Our brains are outsourcing their memory function to search engines and to
04:13Our cell phones.
04:14This gives us a sense of omniscience, as if we had all the knowledge of...
04:20The world at your fingertips.
04:22But it's the opposite of that.
04:25Today we know less, but we have the impression of knowing everything.
04:29This dependence makes us cognitively lazier and perhaps less capable of
04:35to make deep and original connections between ideas.
04:39In addition to cognitive changes, the emotional impact is profound.
04:43Social media has become the main stage of modern life, but a stage where everyone shows off.
04:50Just your best version.
04:52The edited, filtered, and perfectly curated version.
04:57As we scroll through our feed, we are bombarded with images of incredible trips.
05:02Perfect bodies, professional success, and fairytale relationships.
05:07Inevitably, the comparison cycle begins.
05:11We look at our own lives, with their ups and downs, their imperfections and challenges.
05:17and we feel inadequate.
05:19This constant comparison is poison for self-esteem and a trigger for anxiety.
05:26and sadness.
05:26The internet not only connects people, it amplifies emotions, both good and bad.
05:33bad, creating peaks of euphoria and valleys of discontent at an impressive speed.
05:40And when night falls, the cycle doesn't stop.
05:44Many of us take our cell phones to bed, giving them that last quick glance...
05:48It turns into hours of scrolling.
05:51The problem is that the blue light emitted by screens tricks our brain, making it think
05:58It's still daytime.
05:59This inhibits the production of melatonin, the hormone that regulates sleep.
06:05The result?
06:06The rise in cases of insomnia and chronic fatigue, especially among young people and adults.
06:14A bad night's sleep affects mood, concentration, and overall health.
06:21It's an invisible cost, but one we pay dearly for the next day.
06:25A simple but powerful piece of advice.
06:28Create offline moments before bed.
06:32Keep your cell phone away from the bedroom.
06:35Allow your brain and body to prepare for true rest, away from the glare of the lights.
06:41incessant on the screens.
06:43In the end, it becomes clear that the digital revolution is not just technological; it is, above all...
06:50Of everything, cerebral.
06:52The internet isn't just changing the world around us, it's changing who we are.
06:57From the inside out.
06:59The way we connect, how we love, how we learn, and how we see ourselves in the mirror, is...
07:06being rewritten in real time.
07:08With every click, every like, every share.
07:12The issue isn't being against technology, but rather understanding its impact in order to use it.
07:19in a more conscious and healthy way.
07:21If this video made you think, if it prompted you to reflect on your own relationship with
07:26The digital world, leave your like, subscribe to the channel and share with someone who
07:31You also need to hear this message.
07:33Because the more we understand the impact of the internet, the more power we have to become...
07:39Masters, not slaves, of our own attention.
07:43Thanks for watching, and see you next time.
