Because the more work you do, the more oxygen your body needs. As you do more work, your body uses more oxygen. And if you don't breathe faster, you could pass out. That's why it's important to breathe faster with more work.

What does a person tends to breath faster when they run?

A person tends to breathe faster when running to meet the increased oxygen demands of their muscles during physical exertion.

Faster breathing helps to supply this oxygen more efficiently and maintain optimal performance. Additionally, the increased heart rate during running supports this enhanced respiratory rate.
