Keeping Your Brain Healthy And Smart: Keep Active And Learn New Things
For years fitness enthusiasts have suspected that exercise positively affects the brain as well as the body. But while it seemed logical that an active lifestyle would help the brain, the scientific evidence was lacking.
Now several biological studies indicate that working out does benefit the brain.
The reasons to get moving are greater than you think. Now researchers are finding biological evidence that exercise benefits specific brain mechanisms. And, it even contributes to growing new neurons! While we used to think that the brain loses cells as we age, we now know it is not true for those people who keep active and learn new things.
Much of the new research suggests that exercise positively affects the hippocampus, a sea-horse shaped brain structure that is vital for memory and learning.
In one recent study, researchers found that adult mice doubled their number of new brain cells in the hippocampus when they had access to running wheels. The fact that the mammalian adult brain can increase its number of brain cells is surprising in itself. This is good news for aging...
