IN PRAISE OF WALKING, by Shane O’Mara (2019)
I have to admit, it isn’t often that I get validation from a scientist to indicate that I’m on the right track to live a long and healthy life (if I don’t get hit by a bus, first! Ha-ha!). As a child, in the primary grades, I was too busy to sit still. I can remember kids being told to “sit on your hands” (in order to pay better attention). That was a struggle. Like Jean-Jacques Rousseau, I couldn’t think unless my body was moving. Nowadays teachers realize that small children need to move to learn. So Shane O’Mara’s message hits home.
As a neuroscientist, Shane goes into great detail about the positive effects of walking, on our brain health, through the spinal cord, and on our lung and heart health. He goes to the cellular level in the hippocampal formation of the brain, which is responsible for memory and cognition. For example, neurogenesis—the growth of the network of tiny blood vessels that carry oxygen and nutrients to brain cells—happens in the hippocampal formation, when actively-working muscles (arms, diaphragm, abdomen, neck and legs) produce a certain molecule which is Continue reading
