Over at brain health we find out that exercise can reverse the normal age-related shrinking of the brain. Walking 40 minutes 3 times a week can not only stop the normal shrinking of the brain but actually reverse the process (the hippocampus grew by 2%, while in the control group it shrank 1.4%).
And even more importantly:
Reassuringly, the reversing of the hippocampus shrinkage was accompanied with an improvement in memory function. Therefore, exercise improved both the morphology of the brain but also a real life functional outcome such as memory. You couldn’t ask for much more.
So today get out there and get in some exercise: walk, run, bike, hike, dance, anything.
