What are the causes of forced breathing?

Forced breathing, or active breathing, typically occurs during physical exertion or stress when the body requires increased oxygen intake. It is driven by the body's need to expel carbon dioxide more rapidly and maintain adequate oxygen levels in the blood. Factors such as exercise, anxiety, and certain medical conditions can trigger this response, activating the respiratory muscles more intensely than during normal, passive breathing. Additionally, the body's autonomic nervous system plays a role in regulating this process.
