Question

When do we breathe faster?​

Answer 1

When you are doing increased physical activity, such as cycling, running or climbing, your breathing becomes faster. As well as bringing oxygen into the body more quickly, this speeds up the process of getting rid of carbon dioxide. Your brain sends out instructions to your body to increase the rate of respiration.
