Walking Is Great, but More Is Better

Walking is definitely good exercise, but the more aerobic activity we incorporate into our lives, the better off we’ll be, both mentally and physically. A study by Kirk I. Erickson of the University of Pittsburgh, published in the Proceedings of the National Academy of Sciences, found that regular aerobic exercise (the kind that really gets your heart pumping) can actually increase the size of the hippocampus, which is the area of the brain that is responsible for transferring information we receive into memory.18

Other experts support that claim too. Scott McGinnis, a neurologist at Boston’s Brigham and Women’s Hospital, confirms that “engaging in a program of regular exercise of moderate intensity over six months or a year is associated with an increase in the volume of selected brain regions.”19

In addition, at least one study has shown that older adults (aged sixty to seventy-nine) who participated in aerobic training showed significant increases in brain volume after six months as compared to those who did only stretching and toning exercises. Stanley J. Colcombe at the University of Illinois and his fellow researchers concluded that “cardiovascular fitness is associated with the sparing of brain tissue in aging humans.”20

And finally, in an observational study of 876 people who were enrolled in the Northern Manhattan Study (a research study of stroke and stroke risk factors in the Northern Manhattan community), Joshua Z. Willey and his fellow researchers found that among those who showed no signs of memory or thinking problems at the start of the study, those who reported low activity levels showed a greater decline over five years on tests that measured how fast they could perform simple tasks and how many words they could remember from a list, than those who reported high levels of activity. The difference was equal to that of ten years of aging.21

Furthermore, as we mentioned in chapter 1, regular exercise has been shown to reduce negative reactions to stress, probably through a series of chemical reactions in the body. Several studies support this finding, including one done by researchers at Princeton University and reported in the Journal of Neuroscience.22

Many of my own clients have also told me that until they began working out with the ReSYNC Method, they had trouble quieting their minds to fall asleep, and that they now sleep better and therefore wake up more focused and energized the next day. Several studies, including one by Helen S. Driver and Sheila R. Taylor, published in the Sleep Medicine Reviews,23 have affirmed the connection between regular exercise and more deep sleep, but even without those studies, I can tell you that I know firsthand that it is true—and not because the people are more tired. As I saw with my client David and hundreds of others, exercise clears the mind, and once your mind is clear, you are able to stop worrying, relax, and get the sleep you need.
