Lots of people work more than 40 hours a week. Now a major British study shows that large amounts of overtime work is associated with an increased risk of coronary heart disease. Since to a large extent heart health is also brain health, it looks as though overtime work might have a negative effect on your brain as well.
In giving talks to community groups about brain fitness, I emphasize that a number of elements go in to brain fitness. And one of these key elements has nothing to do with high-tech computer training. For optimal brain fitness, a sense of purpose is crucial. You have to have a reason for getting out of bed in the morning.
Aerobic exercise has been shown many times to improve cognitive function, but a recent study shows that strength training can improve executive functions. Executive functions are important because they are a mental ability that helps us make decisions and do several things at once (like driving).
Being bored can increase your risk of death from cardiovascular disease according to a recent report. If brain fitness means keeping interested in life and mentally active, then an active brain fitness program may help you avoid the risk associated with boredom.
How old you feel makes a difference in how you think your brain is working, especially for women. And once again, mood and self-efficacy make a difference for everyone in what they think is going on with their brains.

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.
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. (more…)
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. You can see a video presentation by him on YouTube by clicking here.
