Brain Fitness Tip of the Week: Stress

Focus on stress. Our own, and many other researchers’ work, has shown that stress has a negative relation to memory. Stress may affect how well you can pay attention, and the chemicals it increases in our body (sometimes called stress hormones) may have a negative impact on your body. Whatever the cause, stress has a negative effect on your ability to remember what you want to remember.

What to do? First, check out your stress level. Do you often feel tense, worried, and jumpy? Stress might be the reason. How often do you feel out of control, or as though events have gotten away from you? Those are the sorts of experiences that make for increased stress. People sometimes forget that we adapt to stressors, so that after some time we may not even notice how stressed we are.

Simple ways to control stress include mental “time outs,” relaxation, and exercise. Mental “time outs” mean simply taking a few minutes once or twice a day to shift gears. Stop the headlong rush through the day for just a few minutes. Do something else for 10 minutes, but be sure that you take a few seconds to breathe and mentally shift gears. Still better, practice relaxation for 15 minutes twice a day. Simply sit in a comfortable chair, close your eyes, and focus on relaxing the muscles of your body from your head to your feet. Finally, exercise five times a week. It doesn’t mean that you have to go to a gym and lift weights or train for a marathon. Just walking 30 minutes can make a difference

The most important things are to notice your stress level and make a plan for dealing with it. Your memory will thank you.

Mindfulness meditation as practiced over a long period by experts makes clear changes in someone’s brain function. But what about those of us who don’t have a few years to sit in a monastery in the Himalayas? A new study shows that even brief meditation practice can improve attention.

Researchers at Wake Forest University studied whether just four days of training (at just 20 minutes a day) could make a difference in participants’ mood, energy, and cognition. Undergraduate students (average age 22 years) either participated in the meditation sessions or spent a similar amount of time sitting quietly and listening to an audio book.

Participants in the meditation condition showed decreases in anxiety and improvements in several mental processing tasks compared to those in the audio book group. The meditators’ performance on one aspect of a working memory task (how many answers they got correct in a row) suggested that they may have improved their attention.

This is a small and very preliminary study that extends others’ work on meditation and the brain.It shows that even brief meditation practice can make a difference. you don’t have to be a Buddhist monk to learn to still your mind and pay better attention. Paying attention may be one of the most important things you can do to improve your brain’s functioning.

I saw an interesting blog post yesterday evening on the site of the Huffington Post about the potential benefits of meditation – or at least about what one woman thinks might be the benefits. Priscilla Warner writes about the contrast between Tibetan monks’ apparent calm, evident even on brain scans, and her own anxiety disorder. Ms. Warner says that she suffers from panic disorder, a severe form of anxiety in which a person can have multiple anxiety attacks every day, even in the middle of the night. Her post is titled “I Want the Brain of a Monk” Although most people don’t suffer from anxiety this severe, many people have symptoms of anxiety. And research has consistently shown that higher levels of anxiety are related to more memory problems.

What’s the relation to brain fitness? In my brain fitness class, I often mention the usefulness of meditation in helping reduce stress and anxiety, both of which have negative effects on memory. You don’t have to go to Tibet to get the benefits of meditation. If you simply take 10 minutes several times a day to break in to the ongoing rush of getting things done, you’ve made a start. Use those 10 minutes to sit quietly, relax your muscles, and breathe deeply.

If you do that every day for two weeks, I think you’ll notice that you feel calmer and better able to focus. And if you’re better able to focus, you will be better able to pay attention and remember things.

Although many people are excited about the potential for using computers to train their brains, we shouldn’t forget that other techniques have been used to the train the brain for many centuries. I’m thinking about the large number of techniques for meditation. While free computer software still requires an investment in a computer, meditation only asks you to sit or lie quietly and focus your mind.

A recently-published study shows parts of the brain in long-term meditators are larger than the same parts of the brain in people who don’t meditate. The article by Eileen Luders and her colleagues appeared in a recent issue of the journal Neuroimage (Vol. 45, No. 3, pp. 672-678, April 15, 2009). The study showed that portions of the orbitofrontal cortex and the hippocampus were larger in persons who had been regular meditators for 5 or more years. The study is interesting because the parts of the brain that were larger are often thought to be important in helping people keep themselves emotionally balanced.

A number of strategies are likely to be helpful for meditators. There has been a great deal of interest over the last several years in mindfulness meditation. Researchers have studied how it can be used in reducing anxiety and depression. Mindfulness is based on Buddhist meditation (for a brief article, click here) but you don’t have to be a Buddhist to practice meditation. In fact, one of the most important persons who has promoted mindfulness is Jon Kabat-Zinn, a researcher at the University of Massachusetts.
