Older men and women who walked for six months showed improvements in white matter and memory, while those who danced or did stretching exercises did not.
Exercise can freshen and renovate the white matter in our brains, potentially improving our ability to think and remember as we age, according to a new study of walking, dancing and brain health.
It shows that white matter, which connects and supports the cells in our brains, remodels itself when people become more physically active. In those who remain sedentary, on the other hand, white matter tends to fray and shrink.
The findings underscore the dynamism of our brains and how they constantly transform themselves — for better and worse — in response to how we live and move.
