Would you believe me if I told you that there are several reasons not to multitask? No way! Multitasking is the buzzword we think is the ultimate hack to getting more done in less time. Unfortunately, it is not! In fact, it is actually one of the sneakiest productivity killers out there.
Think about it: juggling between answering emails, checking Slack, skimming through an article, and brainstorming ideas for your business strategy sounds like being “super productive,” It is however just chaos in disguise.
What is Multitasking?
Multitasking is when you try to do more than one task at the same time or switch between different tasks quickly. It seems like a time-saver, but here is the catch: the brain is not wired to focus on multiple things simultaneously.
Instead, it is constantly bouncing back and forth, which is called “task switching.” because all you are really doing is just repeatedly breaking your focus.
Each switch means your brain has to reorient, which drains energy and slows you down. So, multitasking is not about getting more done, rather, it is about spreading your attention too thin, making you less efficient overall.
The Effects of Multitasking on the Brain
Here are the facts. Our brains can’t actually handle doing multiple things at once. What we’re really doing is “task-switching,” and every time we jump from one thing to another, we lose focus, energy, and time.
For example, ever tried replying to an email while half-listening to a Zoom call, and keeping an eye on your phone notifications? Yeah, been there—ended up sending a totally garbled email AND missing the main point of the meeting.
This is where it gets even trickier. Research shows that multitasking increases your brain’s production of the stress hormone cortisol and can actually lower your IQ by up to 10 points when you are actively switching between tasks.
No wonder it leaves you feeling mentally drained by the end of the day! So, next time you catch yourself with 10 browser tabs open, remember that your brain likes to do things one step at a time.
How Multitasking Derails Productivity
The irony is that when you try to do everything at once, you end up getting almost nothing done. It’s like running on a treadmill—you’re moving, but you’re not actually going anywhere. Studies have shown that shifting between tasks can reduce your productivity by up to 40%. That’s a huge chunk of your day wasted just from trying to keep up!
Assume that you are working on a report. Suddenly your phone dings, so you stop to check it. Then you remember you were supposed to send a follow-up email, so you dash over to your Outlook and—whoops—there’s a proposal you forgot to review yesterday.
By the time you get back to that report, you have already lost your train of thought. Sound familiar? The constant back-and-forth shreds your focus, making everything take way longer than it should.
This is called “context switching,” and is not a friend of efficiency! Each time you switch, it takes your brain 15-20 minutes to fully refocus. So, instead of “getting more done,” you’re stretching out simple tasks and making everything feel twice as exhausting.
The takeaway? Keep your focus on one thing at a time. Multitasking is just tricking you into thinking you’re a productivity champ when it’s actually stealing your time.
Examples of Multitasking
Some everyday examples of multitasking:
- Answering emails while participating in a virtual meeting.
- Scrolling through social media while watching a TV show.
- Texting a client while working on a business proposal.
- Cooking dinner while helping your kids with their homework.
- Talking on the phone while checking your calendar or notes.
- Listening to a podcast while writing a blog post.
- Switching between multiple browser tabs to research and respond to messages.
- Juggling between taking customer support calls and updating order statuses.
We’ve all probably done most of these without even thinking about it, but they’re prime examples of how multitasking scatters your focus. The key is recognizing when you are splitting attention and finding ways to avoid it. Even small distractions add up quickly!
5 Ways Multitasking Can Tank Your Productivity – Reasons Not to Multitask
Here are five reasons not to multitask:
Increased Errors: When you’re juggling multiple tasks, details slip through the cracks. It is easy to overlook mistakes in reports, misspell emails, or forget key points in conversations because your brain is spread too thin. Doing several different things at once can impair cognitive ability, even for people who multitask frequently.
In fact, research suggests that people tend to overestimate their ability to multitask, and the people who engage in this habit most frequently often lack the skills needed to be effective at it..
Reduced Focus and Attention: Constantly switching between tasks reduces your ability to concentrate. It’s like trying to listen to two songs at once—neither sounds right, and it’s exhausting to process both.
Longer Task Completion Time: Each time you switch tasks, it takes your brain a few minutes to reorient itself. This phenomenon, known as “switching cost,” adds up, making everything take longer than it would if you stuck with one task.
Decreased Memory Retention: When your attention is split, you are less likely to remember key details. This is especially problematic if you’re multitasking during meetings or trying to learn something new.
Higher Stress Levels: The constant back-and-forth between tasks triggers stress responses in your brain. More stress = more burnout = less productivity over time. Basically, it’s a recipe for feeling overwhelmed!
Single-Tasking: The Secret to Real Efficiency
It is possible to make certain changes that will increase your productivity and efficiency. Next time you find yourself multitasking, take a quick assessment of the various things you are trying to accomplish. Then, determine which task you need to focus on first. Try to:
Limit the number of things you juggle at any given time to just one task: If you do need to work on multiple things at once, try to combine something automatic, like folding laundry, with something that requires more focus, like having a conversation.
Use the “20-minute rule:” Instead of constantly switching between tasks, try to fully devote your attention to one task for 20 minutes before switching to the other.
Batch your tasks: If you are having trouble resisting the urge to check your email or engage in another distracting task, schedule a set time in your day to tackle it. By batching similar tasks together and setting a time to handle them, you can free your mind up to focus on something else.
Simple fix? Try batching similar tasks together instead. Answer emails all at once, focus on content creation separately, and save social media for a designated time block. Your brain (and sanity) will thank you.
Limit distractions: This may mean seeking out a quieter place to work, switching your phone off, and turning off notifications and alarms.
Practice mindfulness: Adding mindfulness to your daily routine may help you notice the times when you are multitasking. Mindfulness can also improve your ability to focus and pay attention to one thing at a time.
Conclusion – Reasons Not to Multitask
Multitasking might look like a smart way to tackle your to-do list, but it is actually a sneaky productivity thief. Instead of getting more done, you are actually increasing errors, losing focus, and draining your energy.
By switching to single-tasking—focusing on one thing at a time—you will not only get through tasks faster but also feel less stressed and more accomplished.
So, next time you are tempted to juggle three things at once, remember: it’s okay to slow down and tackle them one by one. Your productivity (and sanity) will thank you!
