The average American consumes around 34 gigabytes of information, and more than 100,000 words every day while checking their phone roughly 96 times (that’s once every 10 mins).
In a world where constant notifications, endless scrolling, and 24/7 media access, our brains are melting under the pressure of having to process wave after wave of information - often with little to no opportunity to rest.
Perhaps you’ve already noticed the effects.
You find yourself in a bad mood for no apparent reason. A “quick scroll” somehow turns into an hour, you feel anxious, distracted, or mentally drained despite doing very little.
If this sounds familiar, you may be experiencing what is increasingly known as digital overstimulation.
What is Digital Overstimulation?
Digital overstimulation happens when your brain receives more sensory input than it can handle.
That raises an interesting question: How much information can the human brain actually handle?
The answer may surprise you.
Our brains are a bottleneck by design. We take in up to 10 billion bits of sensory information per second, but our brains discard 99.9% of this to focus on everyday tasks that really matter.
In fact, researchers at the California Institute of Technology (2024) found that the speed of conscious thought is only 10 bits per second: far slower than our sensory intake.
The Grocery Store Analogy
To understand this, imagine walking into a grocery store.
Instantly, your brain takes in dozens of conversations, background music, bright colours, product labels, movement all around you, temperature, the smells of flowers and freshly baked bread.
Yet consciously, you’re probably thinking: “Milk. Eggs. Where’s Aisle 3?”
Your brain registers all of this sensory input but discards 99.9% before it ever reaches your conscious awareness. What’s left is the small slice your brain decided was worth your attention - Milk. Eggs. Aisle 3.
Why Modern Tech Overloads the System
The challenge is that our brains grew up in a very different world.
From the very moment your alarm rings, you are bombarded with alerts, emails, and endless notifications. Social media quickly spikes dopamine levels, triggering a cycle of craving that your brain struggles to shut down. This phenomenon - often referred to as “brain rot” - leaves you exhausted and yet unable to unplug.
What are the Results?
The immediate impact is quite stark, and perhaps you’ve felt it before after spending an entire weekend binge-watching a series. You emerge from the shadows of your house feeling drained rather than refreshed. Oftentimes, symptoms include:
Increased irritability
Difficulty relaxing
Mental fatigue
Excessive worry or anxiety
Mood swings
Reduced motivation
Feelings of hopelessness
A study in teens linked excessive device use to increased rates of depression and suicide. The study did not show that screen use causes depression and suicide. But it suggested that teens who use screens excessively are more likely to be unhappy.
At a certain point, you may also experience physical problems if you continue, such as:
Visual problems: When we watch screens for too long, we overwork our eyes. This can cause problems such as eye strain, blurred vision, and dry eyes.
Problems with sleep: For example, when you use your phone right before going to sleep, you might find it difficult to switch off mentally, making it harder to fall asleep.
High blood pressure: When device use leads to a lack of physical activity, it can also put you at greater risk of chronic health problems such as high blood pressure.
How to Give Your Brain a Break
Designate Tech-Free Zones
Pick one area of your life where technology isn’t allowed: your dinner table, bedroom, or family time.
Replace Screens with Something Better
Replace digital overstimulation with something genuinely enjoyable: board games, reading, drawing, gardening, cooking, or any other hobby you may have. Make it feel good and rewarding to disconnect.
Automate Your Boundaries
Use certain digital tools to set and forget your screen limits. Block YouTube at bedtime, silence WhatsApp after hours, or create a deep work zone during your most productive hours.
The Bottom Line
Digital Overstimulation occurs when technology use becomes so frequent that we struggle to disconnect, and our brains struggle to process and recover from the constant flow of information. This can lead to some major negative consequences. So if you’re experiencing digital overload, get outside, or try one of the methods above to disconnect, and enjoy the feeling of being fully present again.
