periods of time), 48 of the 49 women became pregnant
and went on to deliver healthy babies.
One of the essential points to know about this much
needed chemical is that carbon dioxide is the body’s
natural bronchodilator (opens up the air passages of the
lungs) and is a potent vasodilator (relaxes the blood
vessels). A body low in carbon dioxide will manifest
spasming of the smooth muscle which lines the blood
vessels; this means that there will be a decreased
ability for blood to circulate, from the brain to the
pancreas to the toes and everywhere in between. This
fact stands behind the basis of “eucapnic” breathing:
when carbon dioxide levels are increased, circulation
and oxygenation improve throughout the body.
The most efficient means of slowing carbon dioxide
release is by slowing the breathing rate and depth.
Breathing in and out always through the nose (which is
the beginning of the respiratory system) will insure a
healthy maintenance of CO2, as rapid exhaling through
the mouth depletes CO2 more rapidly than any other
factor. Chronic depletion of carbon dioxide will cause
the body to begin compensating through a complex
series of events, which signal the beginning of disease.
Essentially it is a highly developed dance of balance which
is going on within the physiology of our cells at every
moment of our life. Breathing is happening to us whether
we’re sound asleep or going about our daily lives.
The relationship between oxygen and carbon dioxide is
a well-known scientific fact. In any physiology textbook
we will find Bohr’s Law, which states that “oxygen can
only be released into an acid environment”, and carbon
dioxide is that acid component of our blood. To visualize
this, make a tight fist. Imagine this fist to be a red blood
cell, holding on to oxygen as it travels throughout the
blood stream. The only way that fist can relax, or that
the oxygen can be released, is if there are adequate
amounts of carbon dioxide. Because of this, a person
being checked for the oxygen content of their blood can
show a 98% – 99% O2, yet still be extremely short of
breath and acutely or chronically ill.
Carbon dioxide is the chemical which allows the
body to utilize oxygen efficiently. When oxygen
is utilized efficiently, we are able to function at a
more vibrant state of internal homeostasis, and well
being is maximized. When oxygen is deficient, we go
into a state of anaerobic metabolism, which
ultimately draws resources away from certain cells in
order to support others. It is estimated that about
85% of the work of maintaining normal pH in the
body is carried out by the respiratory system; the
kidneys respond by their regulation of bicarbonate,
which is the alkaline component. These two organs,
the lungs and the kidneys, work together to keep this
delicate balance of internal equilibrium.
The respiratory system is the only system of our
bodies of which we have both voluntary and
involuntary control of at any given moment. During
acute trauma, shock or surprise, our sympathetic
nervous system kicks in with the well-known “fight or
flight” reaction: blood pressure increases, our pain
threshold increases, blood gets diverted away from
the extremities towards the head and torso, and
respiration increases. During meditation, all of the
reverse is true, and breathing automatically slows
down. And, whenever we choose, we can increase
or decrease our breathing voluntarily, although it’s
more difficult to lower our blood pressure at will, or
decide to send more blood to the brain when we’re
trying to memorize something important.
Other stressors such as dehydration, nutritional
deficiencies, over-stimulation of our senses with
constant noise, lights, temperature regulating and
illness will contribute to overbreathing, since
breathing is the place where our body automatically
speeds up in order to compensate. So, as human
beings have created an external “world out of
