Pranayama is the practice in which one learns to regulate one’s breath in order to gain steadiness of the mind. The practice works on our mind, intellect and deeper states of awareness. During the practice, we tap into our parasympathetic nervous system which is responsible for activities when the body is at rest.
During Pranayama, we actually do not take in more oxygen or even seek to increase our lung capacity, instead we are increasing the quality of CO2. We do this through double exhalation.
