While you may have been told (most likely by parents referencing the “This is your brain… and this is your brain on drugs” public service announcements) that once you lose brain cells you can never get them back, new brain cells can be created—and exercise helps trigger that process. By exercising you not only build muscle. You build a bigger brain.

Exercise also makes those new brain cells more effective. According to Reynolds,





So how much exercise is enough to build a better brain? Most studies have focused on aerobic activities like running or swimming. But even walking can make a difference. One study showed that older people who walked for just 40 minutes three days a week took two years off the “age” of their hippocampus—and improved their memory function.

So don’t take a walk at lunch just to clear your head.

Take that walk to get smarter, too.
