Trying To Do Too Much?
New Research Says Multitasking Actually Slows You Down. Here's How To Be More Productive--And Less Crazed
By Alexis Jetter
More from Good Housekeeping
Lisa Maxwell, 31, a fitness trainer and mother of three from Cookeville, Tennessee, considers herself a master multitasker. She routinely answers her children's homework questions while running on a treadmill, and she drills her kids on spelling from a list she reads while driving them to school. Of course, there is the occasional mess-up: Last summer, she was cooking, cleaning, and helping her kids with their science projects when she noticed the house smelled funny. "We had guests coming, so I'd sprayed what I thought was room deodorizer," she says with a rueful laugh. "I'd done half the house before I realized it was Pledge."
Most of us can relate. In fact, multitasking-starting one task before finishing another, a kind of warp-speed juggling-feels like the only way to power through our to-do list these days. Like the subtitle of psychiatrist Edward Hallowell's new book, Crazy Busy, we are "Overstretched, Overbooked, and About to Snap." But are we really getting more done? And at what cost?
If you're reading this while doing something else, stop for a second. Because new studies are proving that the old adage is true: You really can't do two things at once-at least not well. And the research also shows something most of us would never suspect: If you multitask relentlessly, you can jeopardize your health in ways both large and small.
The idea of multitasking comes from computers, which appear to perform many functions at the same time. But the analogy is misleading. Most computers flip back and forth between tasks-and your brain operates in much the same way. It is literally impossible to pay conscious attention to more than one thing at once, notes Dr. Hallowell, a former Harvard Medical School instructor. So "you end up paying conscious attention to several tasks in rapid succession: making macaroni and cheese, unloading the dryer, feeding the dog," he explains.
But switching between tasks wastes precious time because the brain is compelled to restart and refocus. "Each time you have this alternation, there's a period in which you'll make no progress on either task," says David Meyer, Ph.D., director of the Brain, Cognition, and Action Lab at the University of Michigan. "It's mental dead time." The result: It takes longer to finish any one chore, and you don't do it nearly as well as you would had you given it your full attention.
Good stress, bad stress
Multitasking, almost by definition, involves stress-which means the brain signals the body to begin the rapid-fire release of the fight-or-flight hormone cortisol. Of course, stress is not always a bad thing. You need your brain's stress response to help you perform well under pressure, says Esther Sternberg, M.D., author of The Balance Within: The Science Connecting Health and Emotions, and a leading researcher at the National Institute of Mental Health. It's what gets you out of danger or past that deadline. But if you multitask continually, Dr. Sternberg warns, "your brain and your body don't have time to recover from that rush of cortisol. And that can make you sick."
Here's why: Cortisol is also the body's most potent anti-inflammatory drug. And if too much of it is pumped out continuously, "your immune cells are not going to be able to fight infection when they need to," explains Dr. Sternberg. Cortisol overload, she adds, can contribute to serious medical problems such as high blood pressure, heart disease, and stroke.
And that's not all: Over time, say experts, stress can kill neurons in precisely the area of the brain that multitaskers rely on: the prefrontal cortex, which helps you switch between tasks and stores key memories.
Finally, the stress of multitasking may also impair your ability to concentrate. "We've so trained ourselves to be ready for interruption that we're not paying attention to anything," Dr. Hallowell maintains. "The two things that people think they have these days-but don't-are attention deficit disorder (ADD) and Alzheimer's disease. They're just overloaded from a severe case of modern life."
Cell-phone peril
Dr. Hallowell's description would seem to apply to Michelle Silverman, who has turned multitasking into an extreme sport. Every weekday morning, Silverman, 33, a lawyer and new mother from central New Jersey, gets into her Volvo sedan, veers onto the highway, and pulls out her cell phone, BlackBerry, and breast pump. As she slides into traffic, Silverman punches out e-mail messages and holds a conference call with clients, while simultaneously affixing the pump to her right breast and plugging it into her car adaptor. "I know I'm not alone," says Silverman, referring to her behind-the-wheel high-wire act. "Why else would they make breast pumps with car adaptors?"
Yet multitasking behind the wheel is a very risky business. Last year, researchers at the University of Utah reported that attempting to navigate traffic while talking on a cell phone increases the chance of an accident 500 percent-making it at least as great a risk as driving drunk. While talking on a cell phone, the drivers in the study failed to notice even life-or-death cues such as red lights up ahead. And drivers who used a hands-free phone fared no better. That's because the problem isn't physical dexterity-it's focus. In the human mind, what you're thinking about takes precedence over what you're actually seeing or doing.
A distraction is to blame for nearly 80 percent of all traffic accidents, according to another recent study, this one sponsored by the National Highway Traffic Safety Administration. And cell phones were the main culprit. (However, talking to a passenger while driving isn't nearly as risky, the Utah study's authors say, because passengers are likely to notice a change in the roadway and stop talking or call the driver's attention to it.)
So much for driving and cell phoning. But reality check: Is it ever OK to multitask? Actually, yes-when one of the tasks is so routine, you don't need to concentrate on it at all.
Mind over matter
The control center of the brain, the prefrontal cortex, can handle just one new thing at a time, explains Jordan Grafman, Ph.D., chief of the cognitive neuroscience section of the National Institute of Neurological Disorders and Stroke. But as tasks become more familiar, their operating instructions move deeper into the brain. There, the basal ganglia-islands of nuclei responsible for movement-handle activities that require almost no thought. So, for example, "when you're walking and talking," says Grafman, "the basal ganglia does the walking, while the frontal cortex does the talking."
Another way to look at it: You can combine tasks that use different sensory channels in your brain. It's tough to send an e-mail and carry on a phone conversation (not that many of us don't try). But it's pretty easy to fold clothes while listening to the weather report on the radio-unless, that is, a winter storm warning is announced. As you visualize the coming storm, your mental imagery and actual eye movements will struggle for dominance-and your mind will always win. Soon you'll begin putting mismatched socks together.
Young vs. old
By now you may be wondering: Aren't there exceptions to these rules? For example, aren't young people, with their agile minds, better equipped to multitask than the rest of us? "I'm not comfortable unless I have seven windows open on my desktop," declares Hillary Miller, 26, a playwright and teacher in Brooklyn. Online, she'll read a script, check e-mail, scan a newspaper, and shop for leather-free handbags-pretty much at the same time. But Miller admits she's not really concentrating on anything: "I have no focus. It's just a compulsion."
Young people can switch more quickly between tasks, confirms Jordan Grafman, because they've grown up with the new technology and trained themselves to use it. "But," he adds, "that makes them even more prone to sacrifice quality." Says David Meyer: "The brain is wired in ways that impose limitations. Nobody-no kid, CEO, or world-class athlete-can overcome that."
Turn off, reboot
So how do you get more done without multitasking-or at least without multitasking to excess? Preparation is one answer. Reflecting on the day ahead helps prime the mind, enabling it to rehearse the tasks it has performed before, says Grafman. Prioritize what must get done, and then make a schedule rather than a to-do list, advises Dr. Hallowell.
Discipline is also part of the mix. When you're working, he says, train yourself to deflect distractions, whether it's the ding of the e-mail in your in-box (check it when you're done, or turn off the sound), the start of a favorite TV show (record it for later), or the ring of the phone (let the answering machine pick up).
Most important, spend some part of each day clearing your mind. Meditate, take a walk, exercise, stare into space. The key is to wipe the mental slate clean, giving those overtaxed neurons a chance to recoup. This can yield unexpected benefits: As Dutch researchers recently reported in the journal Science, the unconscious mind is often a better problem-solver than the focused one.
Dr. Sternberg suggests you think about the original multitasking model: the computer. Trying to do too many things at once is like sending e-mail spam to your brain. When that onslaught freezes the computer, the only fix is to turn it off and reboot. Dr. Sternberg believes you should show the same compassion for your human hard drive. "You're pushing your brain beyond its capacity," she says. "You wouldn't do that to your car or your computer. But you do it to yourself all the time. Stop and take a break."
The Joy Of Unitasking: One Woman's Story
By Jenny Allen
Yesterday, watching the news while using the elliptical machine at the gym, I tried to speed up my pace by...turning up the volume on the TV. I do it all the time. I also regularly forget to unplug my headset before walking away, treating my fellow gymgoers to the spectacle of my jerking to a sudden, yanked stop.
I never laughed when people used to joke about President Gerald Ford not being able to walk and chew gum at the same time, because I didn't really find it that funny. I actually can walk and chew gum at the same time. But, truly, I understand why others might find it taxing. When it comes to multitasking, I am more competent only by a hair, and sometimes not even that.
More than once, I've found myself standing in my bedroom closet holding, say, a screwdriver and a cup of coffee, as clueless as a sleepwalker about what I am doing there. And I cannot answer the phone while writing an e-mail without sending the message to the wrong person-or calling the person on the phone by the name of the person I'm e-mailing.
Obviously, I am especially unsuited for multitasking; but I would argue that, while most of us are doing it, none of us is doing it very well.
If you are playing a family board game while making cookies for your block's bake sale, are you really playing a board game with your family, or driving everyone crazy by jumping up to check the oven every five minutes? Why have women signed on to do so many things at once? We don't, after all, expect men to multitask. A man lying on the sofa reading the newspaper is busy. A woman lying on the sofa reading the newspaper is underemployed and interruptible-a signal her family picks up because she herself sends it out. We seem to consider ourselves unworthy unless we make ourselves available to our family and others all of the time-and there's no way to do that without cramming every minute with two or three chores.
Consider the opening scene of a movie (I'm making up the scene, but we've all watched similar ones): A woman drives a car full of noisy children to school while soothing her harried boss on the phone while cooing at the baby who's spit up in his car seat. This scene is not the premise of the movie that follows, which is always about something else-extraterrestrials visiting the woman's suburb or her husband's affair with his 20-year-old assistant or whatever. This scene is there to show us life as usual before everything goes kerblooey-Mom having a normal American day in contrast to the chaos soon to befall her. But entire movies have been built around the premise of Dad having this same day (because Mom died, or went to visit her sister). And these movies are considered hilarious. Dad wiping up baby spit while talking to the boss on the phone-how sidesplitting!
Of course, we women do not do ourselves any favors: "How do you do so much!" we compliment each other. And: "I wish I could juggle as many balls as you!" I think we should stop giving each other points for wearing ourselves to a nubbin, stop comparing ourselves unfavorably to frantic acquaintances who cannot sit still, even for a moment. Let them careen along at hyperspeed while we stay in the slow lane. Maybe, when they get tired enough, they will join us. We'll have them over for a night of our kind of multitasking: doing our nails, say, while watching something really dumb on television. Better yet, just watching something dumb on television. We'll call it unitasking and invite others to join our new club.
