As a Chiropractor working with patients, I see many problems associated with poor breathing patterns. This is mainly brought on by emotional stress and causes us to shallow breathe or “stress breathe”, which means that we breathe using our upper chest and mainly through the mouth. Our body is wired to shallow breathe when the sympathetic nervous system or “flight or fight” nervous system is triggered, and this in turn will disturb oxygen and carbon dioxide levels and create imbalance in the muscles associated with the neck, upper back and shoulders.
Upper cross syndrome is common in patients who shallow breathe, which means there is an imbalance associated with muscles of the upper body, some are too tight and some are too weak. Tightness through the diaphragm is also common, as is mouth breathing.
