Breath: the one autonomic function you can consciously control is the life force that drives our heart rates, blood pressure, and the state of the nervous system. It is an oxygenation machine that cleans carbon dioxide waste and can impact focus, memory, and decision-making. Returning to the breath helps us stay present in the now.
