Question

When breathe is realesed after holding it for few minutes. What happens and give reason for its occurrence?​

Answer 1

Answer:

You breathe harder because your body's need for oxygen increases with exertion. Heavy breathing when you're not moving is a sign that your body has to work harder to get enough oxygen. This may be because less air is getting in through your nose and mouth, or too little oxygen is making its way into your bloodstream.

Answer 2

Answer:

It happens because the level of carbon dioxide starts building up in our blood while we hold our breath. And when we actually start breathing, the demand for oxygen increases in our body due to which we breathe heavily. It later becomes normal.
