In the last blog article I discussed energy sources, and this article, drawing on information from my eBook, Manage your personal energy, published by Bookboon.com, I indicat how our energy is quickly depleted.
We seem to be obsessed with the need to stay connected, check email every few minutes, respond immediately to every email and text message we receive, interrupt ourselves from important tasks to answer our smartphones, and continually disrupt family plans and scheduled events.
Getting more things done faster is no longer limited by technology, but by our brain. Our brain has a limited capacity for processing information, and this limit is being approached and frequently passed by the ever-increasing rate at which it is being assaulted by new information.
Absorbing new information burns energy. And it takes more energy to multitask, make decisions and work on demanding tasks. To maximize brain efficiency, we must protect our brain from energy- draining activities encouraged, if not caused, by technology.
Technology was meant to speed up the completion of tasks, not the behavior of people. We must continue to use technology and all that it has to offer in order to improve both our performance and lifestyle. But we must do so in a manner that protects our health – including the health of our brain. This involves judicious use of the Internet, control of technology, and the practice of moderation as opposed to excess.
In studying how the brain uses energy, scientists have learned that it’s virtually impossible to do two things at once with equal amounts of attention. And attempting to do so consumes energy.
Dr. Amir Allen Towfigh, a neurologist with Weill Cornell Medical Center claims that multitasking can jam up your brain processing. He says our frontal lobes are the main engines directing our attention, and they Whether hiring new employees or deciding to go with a new product, executives sometimes go with their gut feeling rather than plow through all the accumulated information and comparing the pros and cons In business there seems to be a preference for the quick over the right; because there are so many decisions to be made.
Daniel J Levinson, in his book The organized mind, claims that multitasking also disrupts the kind of sustained thought usually required for problem solving and creativity. He also indicated the impact of interruptions when he said the awareness of an email waiting to be answered can reduce our IQ by 10 points.
Interruptions, which are a form of multitasking, also help to use up your daily supply of energy. The average smartphone user checks his or her device about 150 times a day according to the 2014 book, Thrive, by Arianne at Huffington. And according to a study conducted in 2005, it takes an average of 25 minutes to return to a task once interrupted, and people spend only 11 minutes on a project before being pulled away. In addition to self-interruptions are the hundreds of daily distractions resulting from your working environment, including décor, clutter, and other people.
Distractions waste our energy; concentration focuses it. If we have reduced external distractions to a bare minimum by turning off smart phones, engaging voicemail, and working alone in the home office devoid of other people, the bulk of the distractions will still remain. The tendency of our minds to wander or daydream is a function of our reactive brain, which is always on the alert for unusual or sudden motion, sound or sightings.
One U.S study mentioned in an article by Leah Etchler in The Globe & Mail (April 6, 2013) found that employees lose 76 hours per year as a result of disorganization so you have more than just energy drain to be concerned about if you are disorganized.
Disorganization definitely consumes energy, whether by searching for misplaced materials in your office or scanning dozens of folders left unfiled on your computer desktop. Mehmet Oz and Mike Roizen, authors of YOU: On a Diet, claim that visual clutter slows down the brain. They say that’s why clusters of road signs double the chances of missing the one you’re looking for. It also explains why website designers aim for simplicity. So clearing clutter from your desk, office and home and leaving more wide open spaces also helps to clear your mind so it will be more productive and consume less energy.
Organizing your office and home not only helps you to find things, it helps you to find purpose in life as well. According to recent research reported in the July/August, 2015 issue of Scientific American Mind, an ordered life lays the groundwork for the pursuit of larger goals, purpose, and significance.
Fatigue and information overload tend to weaken executive skills, lower your energy level and make you more susceptible to distractions.
Excess cortisol impairs function in the prefrontal cortex – an emotional learning center that helps regulate the “executive skills,” including working memory. The overproduction of cortisol was found in seniors who were experiencing memory loss. And it is believed by many neurologists that memory loss experienced by seniors is largely a factor of stress, not age. Prolonged exposure to cortisol has been shown to shrink the hippocampus by up to 14%.
In stressful situations, your weakest executive skills fail first and become more pronounced. Fatigue and information overload tend to weaken them further. Avoiding, releasing or being able to manage stress is important.
Avoiding, releasing or being able to manage stress is important. You should re-examine your workload. Simplify if possible. Delegate and outsource. Pace yourself.
They all consume energy. As far as your brain is concerned, less information frequently results in better decisions. Too many choices and too much information taxes the brain and depletes your mental energy. Researchers have found that coming to a decision often involves listening to two parts of the brain – one that relies on taking advice and the other on experience. The brain considers both views, sometimes conflicting, and makes a decision.
Experiments show that there is a finite amount of mental energy available for exerting self-control, willpower, problem solving and decision-making. Making decision after decision eventually leads to poor decisions. Similarly it has been shown that exerting willpower reduces your energy.
Too much mental exertion without breaks taxes the executive skills. In fact studies described in Scientific American Mind (May/June, 2011) have shown that people who exert themselves mentally, such as resisting the temptation to eat chocolate or whatever, gave up on problems sooner when presented with them immediately afterwards.
In the next blog article I will suggest some ways to conserve your energy.
