Answer 1

Answer:

When a child feels bored or sleepy, the breathing rate slows down. He also starts yawning as the amount of carbon dioxide in his blood increases due to which the body starts giving out carbon dioxide in form of yawning.

Explanation:

The breathing rate slows down because he does not need more oxygen to carry out metabolism for energy in the body at the time when he is sleepy or bored.

Answer 2

Answer:One is that when we are bored or tired, we just don't breathe as deeply as we usually do. As this theory goes, our bodies take in less oxygen because our breathing has slowed. Therefore, yawning helps us bring more oxygen into the blood and move more carbon dioxide out of the blood.
