Multitasking is the least efficient way of getting things done. We would like to believe that doing multiple tasks at once saves time and increase productivity.
We multitask in many ways, but regardless if we are performing two tasks simultaneously or switching from one task to another without completing the first task, the cost is substantial. Texting and driving might be the worst example.
Hopefully with the knowledge of how it impacts our productivity we can make the better choice.
3 Reasons To Stop Multitasking:
1. Multitasking has been shown to lower IQ
A study out of the University of London shows that multitasking lowers your IQ. It found that participants who multitasked during cognitive tasks experienced IQ score declines similar to what they’d expect if they had smoked pot or stayed up all night. IQ drops of 15 points for multitasking men lowered their scores to the average range of an 8-year-old child.
Researchers have also shown that switching between tasks rapidly can exacerbate existing difficulties with concentration.
2. Productivity drops drastically (Up to 40%)
Multitasking can be thought of as an advantageous trait, especially for employers. The ability to perform multiple tasks at once. Unfortunately, you are a lot more likely to make errors when you switching from task to task than if you did one at a time.
What’s actually going on is task-switching or jumping from one thing to another.
3. Decreases creativity and memory function
Taking on too many things at the same time clouds your mind’s ability to remember important details. The more tasks you add the less efficient your brain is.
The 90-Minute Solution: Ultradian Rhythm
The ultradian rhythm concept was popularized by Tony Schwartz but he was not the first to discover it.
In 1953, a sleep researcher named Nathaniel Kleitman demonstrated that there were at least two major kinds of sleep.
His discovery is often described as the beginning of modern sleep research and used by many to increase productivity. Kleitman proposed the existence of a basic rest-activity cycle, or BRAC, during both sleep and wakefulness. The cycle takes 90 minutes in both states.
He suggested that when we are awake we have a similar movement of higher to lower alertness. This is what’s known as the ultradian rhythm.
