How to Grow a Better Brain

Want to be sharp enough to whip your best friend at the latest video game? Wish you could ignore your little brother long enough to get your homework done? Hoping to raise your grade in math?

Well, guess what? Exercise may be just the ticket. Moving around, also called physical activity, builds more than just your body. It builds better brains, too.

The best kind of exercise for a kid's brain is the kind that makes you breathe hard, gets your heart pumping, and maybe even makes you sweat. It's called aerobic exercise. And you don't have to be in gym class to do it. Playing outside after school, in-line skating, and even dancing can count as this type of exercise.

How Exercise Helps You Learn

It gets blood, oxygen, and other "brain food" to your brain. It also helps your body make more of the natural chemicals that help brain cells grow and survive. And it may simply perk you up. These things may help you learn and do better in school (or even outsmart your brother).

If you exercise and are healthy, you're more likely to:

  • Do better on tests.
  • Stay focused.
  • Give the right answers to questions in class.
  • Remember a math problem long enough to write it on the board.
  • Set and reach your goals.

Scientists have taken pictures of kids' brains, and they've seen the effects of exercise with their own eyes! Kids who are healthier have bigger brains. Well, at least parts of their brains get bigger with more exercise -- the parts that may make you smarter.

So, this is a good time to get moving -- when your brain is still growing. But it's great to know that exercise can also help your brain throughout your whole life, no matter how old you get.

Smart Moves for Your Brain

Studying hard is important, but here are some active things to try:

Jump-start your brain. Got a test coming up? Try race-walking around the playground with your friends at recess before you pick up your pencil. Even a short burst of aerobic exercise can help. Kids have found that walking fast for just 20 minutes before a reading test can make scores go up.
