Reversal of nerve reflexes

Normal breathing is characterized by active contraction of only the inspiratory muscles, such as the diaphragm and the external intercostals; expiration occurs passively on the cessation of this contraction of the internal intercostals. Kapalbhati reverses this process: exhalation is active and inhalation is passive. This induces a reversal in the flow of the nerve impulses to and from the brain, bringing about stimulation and awakening of the brain centres. This is one reason for the brain-stimulating effect of kapalbhati, at least on a physiological basis. It should be noted that the expiratory muscles usually only come into action when there is obstruction to respiration, or when there is a great need of extra oxygen in the system.
