You sit down to work and a WhatsApp notification pops up.
You quickly reply. Then you notice an email. You quickly open the app, it's just another voucher from that online website you ordered from once.
A few minutes later, Instagram lights up.
Before you know it, you've spent half an hour switching between tabs, messages, emails, and social media, yet somehow haven't made much progress on the task you originally sat down to do.
Sound familiar? If focus feels harder than it used to, chances are it's not because you're lazy, distracted, or lacking discipline.
It might simply be because your brain is processing more interruptions than it was ever designed to handle. We call this cognitive overload!
The Average Person Is Interrupted More Than They Realise
Researchers have found that even brief interruptions can significantly affect performance and increase mental workload. And think about the amount of times you're subtly interrupted by a notification...
One study from the University of California Irvine found that after an interruption, it took workers an average of 23 minutes and 15 seconds to fully return to their original task.
That's because attention doesn't switch instantly, as part of your brain remains occupied by the thing that pulled you away.
Which brings us to a concept called attention residue.
What Is Attention Residue?
When you move from one task to another, your brain doesn't completely let go of the first task.
Instead, part of your attention remains "stuck" there.
Researchers Sophie Leroy and colleagues introduced the concept of attention residue to explain why task-switching often reduces performance and concentration.
Their findings showed that people performed worse on a new task when their attention was still partially focused on a previous one.
Think about checking your inbox halfway through writing a report. You may return to the report physically, but mentally, part of your attention is still processing the email.
Multiply that by dozens of interruptions every day, and it's no surprise many of us feel mentally exhausted by lunchtime.
Why Notifications Feel So Hard to Ignore
Notifications are competing for your brain's reward system. And unfortunately, they were designed to keep you hooked.
Every notification carries a degree of uncertainty.
Who messaged?
What happened?
Is it important?
This unpredictability activates dopamine pathways involved in motivation and reward-seeking behaviour.
Contrary to popular belief, dopamine isn't simply the "pleasure chemical." It's heavily involved in anticipation and the pursuit of rewards.
This is one reason social media, messaging apps, and endless scrolling can feel so compelling.
Researchers have described social media platforms as operating on intermittent reward schedules, similar to mechanisms observed in gambling behaviour.
Your brain learns that checking your phone might deliver something rewarding.
And "might" is often enough.
Notifications, Stress, and Mental Fatigue
Many people think stress comes from major life events, but small stressors add up too.
A study published in Cureus found that frequent interruptions from email notifications were associated with higher levels of stress.
Every notification requires your brain to evaluate:
- Is this important?
- Should I respond now?
- Can this wait?
- What does this mean?
These tiny decisions may seem insignificant individually. But collectively, they contribute to cognitive load and mental fatigue.
What Constant Input Does to Memory
Many people struggling with focus also report feeling more forgetful.
This isn't surprising.
Your brain needs periods of uninterrupted attention to effectively process and consolidate information.
According to Wamsley's research, wakeful rest after learning improves memory retention because it gives the brain an opportunity to consolidate information.
When every spare moment is filled with notifications, scrolling, podcasts, videos, or messages, your brain has fewer opportunities to perform this essential housekeeping.
Imagine trying to organise a library while someone continuously hands you new books.
Eventually, the system becomes overwhelmed.
It's Not Just Social Media
Social media often gets the blame.
But the issue is bigger than Instagram or TikTok.
Many of us move through the day consuming information almost continuously:
- News alerts
- Emails
- Slack messages
- Podcasts
- YouTube videos
- Group chats
- Work notifications
- Calendar reminders
Our brains are constantly processing, filtering, evaluating, and responding. When are we going to give it a break?
How to Focus Better Without Becoming a Productivity Robot
The solution isn't throwing your phone into the sea.
Nor is it downloading twenty productivity apps.
In fact, if you're already feeling overwhelmed, adding more systems can sometimes make things worse.
Instead, consider reducing unnecessary cognitive load.
A few evidence-informed approaches include:
Turn Off Non-Essential Notifications
If an app doesn't genuinely need immediate attention, disable its notifications.
Every interruption you remove creates more space for focused thinking.
Create Small Pockets of Single-Tasking
Choose one activity each day where your attention stays in one place. For example, one walk with no interruptions, or one conversation where you're fully present.
No multitasking required.
Leave Space Between Inputs
Try not to fill every spare moment with content.
Allow your brain opportunities to process rather than constantly consume.
This might mean:
- Walking without a podcast
- Drinking your coffee without scrolling
- Waiting in a queue without reaching for your phone
Simple, but surprisingly powerful.
Schedule Phone-Free Time
Even thirty minutes can make a difference.
The goal isn't perfection.
It's creating moments where your brain isn't on constant alert.
Where Nutrition and Supplements Fit In
If focus has felt harder lately, lifestyle factors should always come first.
Sleep, stress management, movement, nutrition, and reducing cognitive overload will have a far greater impact than any supplement alone.
That said, some ingredients have attracted growing scientific interest for their role in cognitive performance.
For example, Lion's Mane mushroom has been studied for its ability to support nerve growth factor (NGF), a protein involved in the growth and maintenance of neurons. Researchers continue to explore its potential role in memory, cognitive function, and brain health.
Ginkgo Biloba has also been investigated for its effects on circulation and cognitive performance.
This is why we included both in our Focus blend. Not as a replacement for healthy habits, but as part of a wider approach to supporting concentration, mental clarity, and cognitive wellbeing.
Because the goal is to give your brain the support it needs to work better.
A Final Thought
If your attention span feels shorter than it used to, you're not imagining it.
Many of us are navigating more information and more demands on our attention than ever before.
Your brain is adapting to an environment that rarely gives it a chance to rest.
And in a world that's constantly demanding more of your focus, giving your brain some time off might be the most valuable things you can do.
