Breathing
Because breathing is a function that occurs without
conscious thought, we may easily take it for granted. Few people think
of using breathing as a tool for improving health. However, intelligent
control of the breath can improve the functioning of both body and mind.
The breath is the link between the body and the mind and therefore gives
us conscious access to unconscious processes in the body. It is the key
to improving our response to stress.
Breathing is both voluntary and involuntary, and
it gives us conscious access to our involuntary nervous system. For example,
when you inhale, heart rate increases, and when you exhale, heart rate
decreases. This occurs because the pericardial sac is attached to the
diaphragm. When inhaling there is a tug on the sinu-atrial node and the
heart rate increases. When you exhale and the diaphragm rises, the heart
rate will decrease. By consciously lengthening exhalation, you can learn
to slow down heart rate. Remember also that the involuntary nervous system
is divided into sympathetic and parasympathetic components. We know that
under stress, the sympathetic nervous system is aroused, and we breathe
faster. The simplest intervention to diminish the adverse affects of
chronic stress is to consciously calm the sympathetic nervous system
by breathing slower and deeper. The ability to consciously shift the
functioning of the nervous system is a powerful tool for treating and
preventing many chronic illnesses.
There is no “right way’ to breathe. You
can use the breath to stimulate the body or calm the body. In order to
learn to use the breath, you must gain awareness of and strengthen the
muscles of respiration. The primary muscle of breathing is the diaphragm.
Breathing with the diaphragm requires the least effort and is the most
calming. When you inhale, the diaphragm contracts expanding the lower
ribcage and upper abdomen. When you exhale, the diaphragm relaxes and
as it rises, air moves out of the lungs. I tell my patients to watch
a baby breathe. They don’t move their chest, the move their belly.
Breathing with the diaphragm fills the lower portions of the lung. Intercostals
and neck strap muscles are accessory muscles of breathing and are used
to fill the upper portions of the lung. They are used to take a deep
breath. The muscles of respiration should be able to fill the lungs from
top to bottom, side-to-side, and front to back.
Healthy breathing requires strength in the muscles
of exhalation. If you don’t empty stale air, there’s no room
for fresh air. The most common lung ailments such as asthma and emphysema
are diseases where the lungs suffer from over-inflation. The abdominal
wall must be able to pull back toward the spine to effectively empty
the bottom of the lung. This movement of the abdominal wall also gives
stability and support to the low back. Intercostals and shoulder girdle
muscles assist in emptying the top portions of the lung. Strong muscles
of exhalation enable you to slow down breathing to calm the body.
Pranayama is a highly sophisticated system for using
the breath to optimize health. The effects of changing and improving
breathing can be applied to multiple health problems including heart
disease, hypertension, lung disease, stress disorders, gastrointestinal
disease, ADD, depression, and musculoskeletal problems. The affects of
breathing may be subtle at first, but the effects are breathing are cumulative
and profound. It is said in yoga that you age as fast as you breathe.
Learning to breathe slowly and deeply quiets the mind and turns our attention
inward to become more conscious of inner processes. Healing from within
only occurs when we are quiet and listen to our bodies.
