The length and
speed of the breath is controlled by the diaphragm (a sheet of internal muscle at
the bottom of the rib cage), the strengthening of which is, in part, the
purpose of ujjayi.
Ujjayi
breathing stimulates the vagus nerve which is the heart of the
parasympathetic nervous system. It controls the
organs of maintenance (heart, digestion, breathing, glands) sending
information from your gut to your brain.
Ujjayi
breathing
dramatically changes how your brain works. If you just do a slow breathing rate
(2 to 4 breaths per minute), you will turn on the vagus. Animals and children
do ujjayi breathing naturally.
