Exercise Makes You Smarter

I knew that puzzles and other brain exercises were being debunked, but this is encouraging:

According to Gretchen Reynolds, author of the soon to be released The First 20 Minutes, a book about the science of exercise, recent research shows that exercise can help your brain resist physical shrinkage and improve cognitive flexibility.

“Exercise,” she writes in this New York Times article, “…does more to bolster thinking than thinking does.”

Here’s why. Your brain is a tissue and so like any other tissue, abuse, lack of use, and especially age causes its performance to decline. Sometime in our late twenties the hippocampus, the portion of our brains devoted to learning and memory, loses about a percent per year in total volume. So it’s no surprise that as we get older we naturally lose some of our memory and learning capacity.

But what is surprising is that, just like with your muscles, exercise can slow or even reverse the physical decay of your brain.
