We create the illusion that many things are getting done at once by switching between various tasks very rapidly. We, as humans, have a finite amount of concentration. Think of our attention like a pie chart – where we either devote ourselves to one task, or pieces of our awareness to many tasks. If attention is being divided, then we are not fully in the mindset of a single job and multitasking becomes counter-productive.
That’s right. You’re actually getting less done in an attempt to complete more things at once. If that’s not motive enough, here are four more reasons you should consider changing your multitasking tendencies.
You’re wasting time
Ironically, multitasking actually causes tasks to be completed more slowly than they would have otherwise. In fact, according to the American Psychological Association, up to 40% of productive time is being wasted . This is due to the time it takes the brain to adjust when constantly switching between tasks. Each time you interrupt one activity for another, it takes a period of time for the brain to focus and work on something new. Narrow your attention to one task and stick to it in order to accomplish goals more quickly.
You’re stressing yourself out
Those who multitask on a regular basis are at risk for increased stress and problems associated with elevated stress levels. Multitasking often causes an increase in a chemical called cortisol, which over time has negative health consequences. Likewise, a study from the University of California Irvine showed increased stress levels of workers receiving a steady stream of emails increased stress levels of workers receiving a steady stream of emails in comparison to those who did not. The constant distraction and attention paid to emails caused a higher heart rate and blood pressure in these employees.
You’re making mistakes
Working on several things at once you are much more likely to make an error, and this likelihood increases when the tasks become complex or involves a lot of critical thinking. Without full attention on the task at hand it becomes impossible to pay close attention to detail, and mistakes will be made and missed. Wouldn’t it just be better to decrease this risk and do it right the first time?
You’re hurting your memory
It exhausts our brain and disrupts short term memory to often shift focus between tasks. For example, a study in the Proceedings of the National Academy of Sciences journal found that people experienced difficulties recalling information regarding a previous scene after a brief interruption from another image . This interruption made it challenging to reengage the brain towards the first image, and this effect was significantly worse in older participants.
So, what can you do to practice monotasking and start getting more done?
- Maximize computer windows to hide distractions
- Use headphones, even without music, to not be disturbed
- Turn of email popups
- Set aside separate email time
- Flip your cell phone over and set it to do not disturb
- Use a conference room
- Just do one thing!
Your work experience could even be improved through paying full attention since this allows the brain to determine its level of interest. Try monotasking in several other areas of life and see the difference it makes in stress levels and performance. In the workplace, keep focused on task completion and making progress for increased enjoyment.
Monotasking is something that may take practice for those who tend to juggle multiple jobs at once, but we as humans have limited cognitive resources that are depleted each time we switch, so it’s important to stay focused only on one thing in order to really conquer a task.
