Have you ever stared at a tricky math problem and felt like your brain was completely asleep?
Running around outside for just ten minutes at recess can suddenly make that same problem easy to solve.
How does moving your legs and arms change what is happening inside your head?

The Brain's Energy Delivery

When you sit still in a chair for a long time, your heart beats slowly, so blood moves gently through your body.
When you sprint, jump, or play tag, your heart beats faster to pump fresh oxygen and nutrients straight up into your brain.
This fresh rush of oxygen powers up the front part of your brain, which is in charge of your concentration—your ability to pay attention to one task without getting distracted.
Does exercise only bring more oxygen, or does it release special helpers inside your brain too?

Brain Power Boosters

When your muscles work hard, your body releases natural chemicals that act like fertilizer for your brain cells.
These chemicals boost your alertness, clear away brain fog, and make it easier for your memory to store new facts.
