The primary factor that controls how fast you breathe is the level of carbon dioxide in the body. When carbon dioxide levels rise, it signals the brain to increase the rate of breathing to expel the excess CO2 and maintain proper gas exchange. While oxygen levels and other factors can also play a role, the carbon dioxide level is the most significant regulator in the short term.
