Get Better Sleep — Starting Tonight

According to sleep experts, I’m doing everything wrong. I don’t have a regular bedtime and often stay up way too late. There’s always one more TV show to watch, one more e-mail to send, one more newspaper article to read. By the time I finally crawl under the covers it’s after midnight, and even then sleep sometimes eludes me. Some nights I toss and turn and fluff and re-fluff pillows for what seems like hours, in search of that sweet spot for slumber. All too soon the alarm clock jolts me out of a pleasant dream. In a fog of fatigue, I hit the snooze button over and over, desperate to catch a few more zzz’s.

That’s my version of our national exhaustion epidemic. Sixty percent of American women sleep poorly most nights of the week, and 43 percent are so drowsy during the day that it interferes with normal activities, according to a 2007 poll by the National Sleep Foundation (NSF). Weariest of all are working moms. Not only do these women spend the least time in bed — averaging fewer than six hours a night — they’re also the likeliest to suffer from insomnia. Stay-at-home moms don’t get off so easily, either. They are likely to complain of waking frequently at night and not feeling refreshed in the morning.

The NSF poll paints a grim picture of the toll insufficient shut-eye takes on virtually every aspect of women’s lives. Sleep-deprived women are likelier to be stressed-out (79 percent), late for work more than once in the past month (20 percent), and too tired for socializing (39 percent) or sex (33 percent). They fight daytime drowsiness with caffeine and do nothing special to wind down at night. In fact, frazzled moms typically spend the last hour of the evening multitasking — finishing chores, squeezing in some time with their spouse and kids, catching up on work — often while also watching TV.

A hectic lifestyle can sabotage sleep, says Carol Ash, DO, director of Sleep for Life, in Hillsboro, New Jersey. “A lot of my patients lie awake at night with racing thoughts. They’re exhausted but their brain just won’t stop humming. As they toss and turn they get increasingly anxious about not sleeping, which only makes the problem worse.”

Stress isn’t the sole reason for restless nights. Misunderstanding what helps — or hinders — slumber also plays a key role, according to Dr. Ash. But sleep problems can be solved — in many cases without pills. The following surprisingly simple natural solutions work by enhancing your body’s own mechanisms for lulling you into soothing, satisfying sleep.

Soak Up Morning Sunshine

Light, especially sunlight, has such a potent effect on your body’s internal clock, or circadian rhythms, that you can use it to reset your sleep cycle, says Phyllis C. Zee, MD, PhD, director of the Sleep Disorders Center at Northwestern University. “If you tend to be a night owl who can’t get to sleep until 1 a.m., you may have delayed circadian rhythms. To shift to an earlier schedule — and make it easier to get to bed and get up on time — soak up as much sunlight as possible between 6 and 8 a.m.” Force yourself to wake up early and sit in a sunny room or take a post-sunrise walk. When it’s warm, try eating breakfast outdoors. Basking in early-morning rays prompts your body to suppress production of melatonin — the sleep hormone — during the day and release it earlier in the evening, so falling asleep isn’t such a struggle. A light box of the type used for people with seasonal affective disorder can help. “Look for one with broad-spectrum light and with a UV filter,” recommends Dr. Zee.

Exercise Early in the Evening

Though it’s known that exercising within three hours of bedtime can leave you too wired to slumber soundly, a recent study by Dr. Zee finds a place for evening workouts. Exercising at least three times a week around 5 to 7 p.m. helped people improve their sleep. It may be that working out then creates a pleasant tiredness that helps the body prepare for sleep. Or it could be that exercise helps women unwind after work or a hectic day at home with the kids and they feel less stressed when they curl up under the covers.

Dim the Lights at Night

“Your body is primed to sleep when it’s dark,” says Marcel Hungs, MD, PhD, director of the Center for Sleep Medicine at the University of California, Irvine. “I encourage patients to dine by candlelight and turn down the lights in their home starting around 7 or 8 p.m.” Avoid surfing the Web or checking e-mail close to bedtime, because the glare from the computer screen can stimulate your brain instead of letting it slow down for slumber. And turn off the tube at least half an hour before you go to bed, adds Dr. Hungs. “Many people doze off with the TV on, only to find themselves wide awake later in the night,” he says. “That’s because the bright, flashing images and noises are mentally stimulating on a subconscious level.” The better bedtime wind-down choice: read (something printed on paper, not an e-book).

Cover Your Clock

One common mistake is keeping the alarm clock next to the bed, says Dr. Ash. “Then you wake up at night and check the time. Seeing that it’s 2 a.m. or 4 a.m. only heightens your anxiety about not sleeping.” She also cautions about the glow from the dial. “Even that little bit of light can signal your brain that it’s time to get up.” Instead, turn the clock to the wall, drape a towel over it, hide it under the bed, or find one without a lighted dial or glow-in-the-dark numbers.

Try a Sleep Herb

Many studies suggest that valerian, a mild sedative herb sold over the counter as capsules or tea, improves sleep and helps people nod off quickly. But most of these studies didn’t use a sleep lab and aren’t considered conclusive proof of efficacy. It can take up to four weeks of nightly use to get the full benefit. Valerian is considered relatively safe for short-term use — up to six weeks. The usual dose is 300 to 900 milligrams, taken 30 to 60 minutes before bed. It’s not recommended for pregnant women or nursing mothers and can cause headaches, dizziness, or upset stomach. Another drawback: Some find its odor reminiscent of dirty socks.

Perfume Your Pillow

Some fragrances can waft you into slumber, says Cherie Perez, RN, who teaches aromatherapy at Houston’s M.D. Anderson Cancer Center’s Place of Wellness. “Lavender is helpful for insomnia, stress, and migraines, while myrrh calms the mind and prepares you for sleep.” Put a couple of drops of either oil on a handkerchief, then tuck it inside your pillowcase. Also use lavender for bath oil (see “relax in the Tub”): Mix two cups of Epsom salts with 15 drops each of lavender oil and orange (sedative/anti-anxiety) oil.

Relax in the Tub

Soaking in warm water can ease the transition into sound sleep — and not just because it relaxes tired muscles. It also triggers a shift in body temperature, a natural cue it’s time for shut-eye, explains Rubin Naiman, PhD, the Tucson-based author of Healing Night: The Science and Spirit of Sleeping, Dreaming, and Awakening. “When the sun goes down, the outside temperature falls, and the same thing happens inside our bodies to prepare us for sleep. After you climb out of a hot bath, you feel a pleasant chill. With the right timing, you can catch that wave and ride it into deep, blissful sleep.”

Your Anti-Insomnia Kit

When you wake up at 3 a.m., it helps to have prepared relaxing activities ahead of time, says Dr. Ash. Put these in the next room:

  • A simple sewing or crafts project, especially knitting or needlepoint
  • A journal or notebook, with pen
  • Crossword puzzles and pencil
  • Magazines or a book that is pleasant but not a page-turner
  • Soft, new age-type music and headphones

Why These Help “The back-and-forth movement of your eyes as you knit, sew, read, or write helps trigger neuro-controls for sleep,” says Dr. Ash. The sound of soft music is relaxing. “Go back to bed the minute you feel drowsy, not before. You want to teach your brain that the bedroom is a calm, comfortable environment for rest.”

The Pillow of Your Dreams

To avoid back or neck pain, elevate your head only one pillow high. “You want a pillow firm enough to hold your head and neck in alignment with your spine, just as they would be if you were standing up,” says Jeffrey Goldstein, MD, director of Spine Service at the NYU Hospital for Joint Diseases.

Feathers, Fiberfill, or Foam?
Feathers Down, the fluffy undercoat of a goose or duck, is the softest, most expensive filling. For more support, choose a mixture of down and feathers or all feathers (firmest). Goose feathers are almost as fluffy as down, with curved quills that add spring. Duck feathers cost less but are less buoyant.

Fiberfill This polyester product is soft, pliant, and moderately priced but may lump during laundering.

Foam This makes the firmest pillow and comes in various shapes, including contoureds to cradle your head and neck. “Memory” foam molds itself to the shape of your head for extra comfort.

A Note About Allergies
“Hypoallergenic” synthetic pillows may not be the best choice — unless you’re allergic to feathers. British studies show feather pillows offer notably better protection from dust mites and pet allergens than synthetics do.

Firm or Soft? Depends on Your Sleeping Position
Back Sleeper Medium-firm pillows bolster your neck without flexing your head forward.
Side Thick, firm pillows give the best support.
Stomach Softer, flatter pillows prevent neck strain.

Pillows for Special Situations
Heartburn Wedge-shape slanted cushions raise the esophagus higher than the stomach, preventing the upward flow of stomach acid that causes this problem when you lie flat. Hot Flashes Choose a pillow that dispels heat; these brands usually have cool or chill in the name.

Foods That Help You Snooze

Some tasty ways to bring on zzz’s:

Go Bananas
Sometimes called a sleeping pill in a peel, this fruit is rich in tryptophan, an amino acid linked to healthy slumber, says Elisabetta Politi, MPH, RD, nutrition director at Duke Diet & Fitness, in Durham, North Carolina. “Tryptophan increases serotonin in your brain and blood, which can improve relaxation.” Other good sources include dairy products, turkey, peanut butter, and tofu.

Relax with Rice
Eating jasmine rice four hours before bedtime helped people doze off more quickly, according to a small 2007 study in Australia. Other starchy foods, such as potatoes or cereal, also do the trick, adds Politi. “A lot of my clients say that when they’re stressed out, pasta helps them sleep better, which makes sense because carbohydrates can raise serotonin.”

Combine Unsweetened Carbs with Protein
A high-carbohydrate, low-protein snack seems to help the brain use tryptophan efficiently, so it produces more sedating serotonin. Try apple slices with peanut butter, a small bowl of oatmeal with low-fat milk, or crackers topped with slivers of turkey. Don’t overdo the protein before bed, since foods like meat or cheese also contain tyrosine, an amino acid that can rev up brain activity.

And don’t…

  • go to bed hungry or too full; both impede sleep.
  • eat rich or spicy foods before bed; they may spark heartburn when you lie down.
  • eat sweets within four hours of bedtime; they’re a stimulant.
  • drink decaf. Almost all decaf coffee has small amounts of sleep-busting caffeine.

Does Melatonin Really Work?

Melatonin supplements are marketed as sleep aids, but how well they work depends on your needs, note researchers at Brigham and Women’s Hospital, in Boston. If study subjects got melatonin at night, when their bodies naturally produce the hormone, the extra dose had no effect. But taken during daylight hours, it increased shut-eye by about 30 minutes, suggesting that it could be helpful for people who work the night shift or are jet-lagged after crossing several time zones. Potential side effects include headaches, stomach discomfort, and dizziness.

Sleep More, Weigh Less

Women who slept five or fewer hours a night were 32 percent more prone to major weight gain (33 or more pounds) and 15 percent likelier to become obese over 16 years than those who got seven hours a night — even though the seven-hour sleepers actually ate more — according to the Nurses’ Health Study, a long-term study tracking 68,183 women. Research shows insufficient sleep can increase levels of the appetite-stimulating hormone ghrelin and boost blood glucose and prediabetes risk.

How to Think Yourself to Sleep

Myth: If I didn’t sleep well last night, I should catch extra zzz’s whenever I can.
Why It’s False: “Getting up three hours later gives you jet lag, like flying from new York to L.A.,” says Jack Edinger, PhD, of Duke University Medical Center. So don’t take a nap or sleep in on weekends.
What Is True: Naps can be healthy if you don’t have insomnia. If you do they’ll make it worse by leaving you less tired at night. No matter how tired you are, don’t nap, and always get up at your regular time.

Myth: Everyone needs eight hours of sleep; I don’t sleep that much so I must have insomnia.
Why It’s False: Worrying about insomnia can make it harder to sleep — or get back to sleep if you wake up in the middle of the night.
What Is True: Anywhere from six to nine hours is normal. If you feel rested, don’t worry about how much shut-eye you’re getting. And know that an occasional sleepless night is not harmful and doesn’t mean you have a serious issue.

Myth: Even though I can’t sleep, lying in bed at least provides some rest.
Why It’s False: “Spending a long period lying awake in bed can make your bedroom feel like a torture chamber, as you get more and more frustrated about not sleeping,” says Dr. Edinger.
What Is True: If you wake up for longer than 15 to 20 minutes, get up, go to another room and do something until you feel sleepy (see “Your Anti-Insomnia Kit”). Then go back to bed. This teaches you to associate sleepiness with bed and gives you tools to resolve your problems.

Myth: I know I won’t be able to sleep tonight.
Why It’s False: This expectation makes you anxious, setting you up for a bad night and a vicious cycle of expecting the worst and therefore being unable to relax while in bed.
What Is True: Knowing you will get up and do something enjoyable if you can’t sleep helps you stop associating being unable to sleep with anxiety and unhappiness.

080118 - Mamás en el extranjero reflexiones

January 18, 2008 by toe200099

Estaba pensando que esto de ser mamá viviendo en el extranjero es diferente ¿no?

Yo leo internet, pregunto aquí y allá, uno crea su network :)  Se mandan fotografías de los niñitos a familaires yamigos. Algunos tienen weblogs o foto álbumes en la web, camarita.

Es diferente… Quizás sea interesante recopilar información y escribir un libro sobre esta época “como ser mamá venezolana en el extranjero y no morir en el intento”…

080115 - Do you recognize the wealth in your life?

January 15, 2008 by toe200099

Most people define wealth in terms of money, nice homes, and expensive jewelry. But truly, children are worth more than their weight in gold! They say the best things in life are free, and while children themselves rarely come without some sacrifice on your part, nothing can compare to building a strong family bond of love. Today, spend extra time with your kids by loving and nurturing them. No one speaks their language better than their mother. Are you stressing out about money? Don’t let your busy, stressful life get in the way of recognizing and cherishing the wealth and treasure in your own home.

071212- Moraleja de el dinero

December 12, 2007 by toe200099

Por el Dr. Marcelo Perazolo - psp-sa.com

—————————————
¿Cuánto Vale un Billete de 50 dólares?
—————————————

Alfredo, con el rostro abatido de pesar se reúne con su amiga Marisa en un bar a tomar un café.

Deprimido descargó en ella sus angustias…que el trabajo, que el dinero, que la relación con su pareja, que su
vocación…todo parecía estar mal en su vida.

Marisa introdujo la mano en su cartera, sacó un billete de 50 dólares y le dijo:

- Alfredo, quieres este billete ?

Alfredo, un poco confundido al principio, inmediatamente le dijo:

- Claro Marisa…son 50 dólares, quién no los querría ?

Entonces Marisa tomó el billete en uno de sus puños y lo arrugó hasta hacerlo un pequeño bollo. Mostrando la estrujada pelotita verde a Alfredo volvió a preguntarle:

- Y ahora igual lo quieres ?

- Marisa, no sé qué pretendes con esto, pero siguen siendo 50 dólares, claro que los tomaré si me lo entregas.

Entonces Marisa desdobló el arrugado billete, lo tiró al piso y lo restregó con su pie en el suelo, levantándolo luego sucio y marcado.

- Lo sigues queriendo ?

- Mira Marisa, sigo sin entender que pretendes, pero ese es un billete de 50 dólares y mientras no lo rompas conserva todo su valor…

- Entonces Alfredo, debes saber que aunque a veces algo no salga como quieres, aunque la vida te arrugue o pisotee SIGUES siendo tan valioso como siempre lo hayas sido…lo que debes preguntarte es CUANTO VALES en realidad y no lo
golpeado que puedas estar en un momento determinado.

Alfredo quedó mirando a Marisa sin atinar con palabra alguna mientras el impacto del mensaje penetraba profundamente en su cerebro.

Marisa puso el arrugado billete de su lado en la mesa y con una sonrisa cómplice agregó:

- Toma, guárdalo para que te recuerdes de esto cuando te sientas mal…pero me debes un billete NUEVO de 50 dólares para poder usar con el próximo amigo que lo necesite !!

Le dio un beso en la mejilla a Alfredo -quien aún no había pronunciado palabra- y levantándose de su silla se alejó
con su atractivo andar con rumbo a la puerta.

Alfredo volvió a mirar el billete, sonrió, lo guardó en su billetera y dotado de una renovada energía llamó al mozo
para pagar la cuenta……”

En el fondo tengo un pequeño malestar con la historia de Alfredo y Marisa. Siempre me queda la sensación que quizás
no logro transmitir el verdadero significado del mensaje.

- Cuántas veces dudamos de nuestro propio valor, de que realmente MERECEMOS MAS y que PODEMOS CONSEGUIRLO si nos lo proponemos ?

Claro que el mero propósito no alcanza…se requiere de la ACCION para lograr los beneficios.

Yo se que se puede y que existen innumerables caminos para conseguirlo. Espero que muy pronto podamos recorrerlos
juntos (para ello sólo te basta con tomar tu decisión de hacerlo).

Que TODOS aprendamos a desarrollar nuestras potencialidades.

071202- Elegancia en el alma, etc, etc…

December 2, 2007 by toe200099

“Elegancia en el alma” esta frase me la dijo una vez una amiga sobre alguien y no se me olvidó… si el comentario fué positivo o negativo, no lo voy a mencionar. Porque se trata de LA FRASE, de lo que comprende y no de ponerle etiquetas a alguien…muy importante.

Para aquellos que algún momento lean esto. Sería interesante que dejaran su comentario sobre lo que significa o su interpretación de lo que voy a escribir aquí… un debate interesante… Creo que lo voy a ir escribiendo poco a poco.

Las diferencias entre estas palabras son de una sutileza casi imperceptible o completamente para algunas personas,. Y no tiene que ver con color, nacionalidad, etc. etc. Depende de el nivel de evolución de la persona, temperamento, crianza, capacidad de crecer por sí mismo, de darse cuenta de cosas, de situaciones, ambiente donde se crió o se desenvuelve la perosna, la estimulación desde la niñez.

Estas palabras son:

ReSPeTo… NoBLeZa… SeNSiBiLiDaD… LíMiTeS… ReCiBiR… DaR… DeLiCaDeZa… aTReViMieNTo… oSaDíA… PeRCePCióN…

… y el compendio de todo esto, es lo que yo llamo

“ELEGANCIA EN EL ALMA” en un grado mayor o menor… ¿Que significa esta frase para tí? ¿Como la interpretarías?

Algunas personas caminan por la vida atropellando sin darse cuenta, querer o poder ver que las consecuencias de sus actos, afectan a los que los rodean enormemente.

Es importante estimular a los niñitos desde temprana edad, de una manera apropiada… ¿pero que es “apropiado”?

071127- Training for Life - Try These Cold Weather Workouts

November 27, 2007 by toe200099

Try these cold weather workouts for any athlete:

If in your past you experienced cold (or hot) weather as a deterrent to working out, this season holds the opportunity of a lifetime for you.

Make this year different. Adopt a true athletic archetype and feel your desire for fitness success emerge. You can use old obstacles as opportunities to gain strength - mental and physical.

  • Breaking through – that is your focus.
  • Not giving up – that is your motto.
  • Making your training a priority rather than a dispensable activity – that is your goal.

“Success is only a word, but achieving it is a lifestyle.”

Make the decision - that’s what you have to do first. Decide that you want to maintain, begin, or improve your training this winter, then take steps to support (and reinforce) your decision.

Then, don’t give up no matter what. Act and think, in all areas of your life, like the athlete you want to be (and look like). Making your health and fitness a priority will be the best gift you give this winter to you and everyone else in your life.

So what do you do if it’s too cold to go outside and you haven’t got time to hit the gym?

Here’s what I do:

1. Lunges across the living room: find enough space to walk/lunge 8-10 paces and do slow, deep walking lunges in your home. Take a long stride and bend deeply as you walk slowly step-by-step working your quads, hamstrings and glutes. Four sets of 8-10 strides on each leg will have you feeling as though you’ve just done leg extensions and squats at the gym.

2. Push up on the stairs, on a bench or on the floor. If you are using a bench be sure that it is securely pushed up against a wall. On the floor, you may want to do your pushups on your knees instead of your toes.

Do four sets of 5-10 reps (and you can even do a little housework in between sets); believe me you will feel your upper body muscles the next day as though you were lifting weights at the gym.

3. Jump rope in the kitchen. Do five sets of 1-2 minutes of jumping rope. You’ll be conditioning your heart, burning excess calories, and revving up your system for a good day.

4. Jumping jacks in the bedroom. Nothing like a few sets of jacks to get your heart rate up and a little sweat going. Do 8-10 sets of 25 jacks and you’ll not only feel your whole body working, but the after effects of feeling your upper and lower body throughout the day will be satisfying and a reminder that you are an athlete in training.

5. Abs anywhere. First of all, keep your abs engaged on all of the above exercises. Then, on a soft surface lie on your back and do three sets of 15 crunches and three sets of 15 leg lifts supporting your lower back by keeping your hands on the floor, palms down, just under your lower back.

6. Begin your day with five minutes of quiet introspection. Sit still, close your eyes and relax. Focus on your breath and let the world become simple and peaceful.

You are on your way to a great Holiday season.
Peace,
Debbie Rocker

071126- Less (Information) Is More

November 26, 2007 by toe200099

When Benjamin Franklin’s nephew Joseph Priestley found himself stumped by a complex life decision, he wrote his sage uncle for advice. In his 1772 letter of reply, Franklin described his own method for reasoning out complex problems, which he called “moral algebra.” Divide a sheet of paper in half, he counseled his nephew, and make an exhaustive list of pros and cons. Then, over a couple days, weigh the pros and cons, and when a pro and a con seem of equal weight, strike them both out. What is left in the balance is the best answer.

Such “balance sheet” calculation is still taught today as the most logical and systematic method for dealing with many of life’s complexities. Kids are counseled to choose colleges and careers this way, and managers similarly deliberate the pros and cons in important business decisions; some people are even methodical in matters of the heart.

But is moral algebra really the best method for decision making in today’s dizzyingly complicated world? Or is there virtue in simplicity for many life choices? A growing number of psychologists are questioning the soundness of Franklin’s method, and its modern iterations, including data-heavy calculations by increasingly powerful computers.

One of the leading challengers to the dogma of decision making is psychologist Gerd Gigerenzer, of the Max Planck Institute in Germany, whose new book “Gut Feelings” collects a convincing body of evidence for the power of hunches over laborious data crunching. Hunches, gut feelings, intuition—these are all colloquial English for what Gigerenzer and his colleagues call “heuristics,” fast and efficient cognitive shortcuts that (according to the emerging theory) can help us negotiate life, if we let them.

Consider the “take the best” heuristic. “Take the best” means that you reason and calculate only as much as you absolutely have to; then you stop and do something else. So, for example, if there are 10 pieces of information that you might weigh in a thorough decision, but one piece of information is clearly more important than the others, then that one piece of information is often enough to make a choice. You don’t need the rest; other details just complicate things and waste time.

Gigerenzer has demonstrated this in the laboratory. He asked a large number of parents to consider a scenario in which their child wakes up after midnight short of breath, wheezing and coughing. They are told that a doctor could make a home visit in 20 minutes; it’s a physician they know but don’t like all that much, because he never listens to their view. Alternatively, they could take their child to a clinic 60 minutes away; the doctors there are unknown, but good listeners by reputation. Which to choose?

There are actually four pieces of information in play here: 20 minutes vs. 60 minutes, home visit vs. driving to the clinic, familiar vs. unfamiliar doctor, and good vs. bad listener. Some parents in Gigerenzer’s experiment did weigh all four pieces of information, but almost half did not. Instead they made this very important decision based on one factor, and for the vast majority that factor was whether or not the physician was a good listener—even if it meant waiting 40 minutes longer for treatment. Many fewer made their decision based on waiting time alone. Nobody much cared about a home visit.

Gigerenzer calls such decision making “satisficing,” as in “satisfying” enough to “suffice.” Satisficers don’t feel the need to know everything, in contrast to “maximizers,” who do want to weigh every detail imaginable in making even minor life decisions. Interestingly, studies have found that satisficers are more optimistic about life, have higher self-esteem, and are generally happier than maximizers.

Gigerenzer has had a hard time convincing other cognitive scientists of the power and accuracy of heuristics. Nobody quite believes that you can make sounder decisions with less information and less time, which is what heuristics claim to do. To prove his point, he has gone head-to-head with powerful computers, which can crunch vast amounts of information in the manner of Franklin’s moral algebra. Consider another experiment involving parents: in this one parents have to choose a Chicago high school for their children, and they want the one with the lowest dropout rate. But that information is unavailable, so how does one make a decision?

Well, there is a lot of other information available, including SAT scores, attendance rates, writing scores, and more—18 pieces of information in all. Gigerenzer had a computer do what’s called “multiple regression” analysis, which is just modern jargon for Franklin’s moral algebra. It estimated the importance of all 18 pieces of available information and did a complex calculation to predict the dropout rate for each school. Gigerenzer also had a computer choose a school using the “take the best” strategy. In this case, it looked first at attendance, but there was no significant difference in the schools, so it moved on to a second piece of information, writing scores. Based only on these two pieces of information, the “take the best” method was more accurate than the complex and time-consuming analysis in determining the actual dropout rates of Chicago schools—and much faster.

Gigerenzer and his colleagues have run similar head-to-head tests on dozens of real-world problems, in fields as diverse as economics and biology and health care. In every case, one good reason has proven superior to data-greedy mathematical equations in making the best choices. Psychologists now believe that these cognitive shortcuts evolved over eons in the brain’s neurons, probably because exhaustive and complex calculation was so often impractical for our early ancestors, who were always only one step ahead of their predators. Today we’re one step ahead of an information tsunami, so it’s comforting to know that the quick and dirty choices we’re forced to make on the fly are grounded in some ancient intelligence.
