Dysfunctional Breathing
“Breathing becomes dysfunctional when the person is unable to breathe efficiently or when breathing is inappropriate, unhelpful or inefficient in responding to environmental conditions and the changing needs of the individual.” (4) Dysfunctional breathing and it's effects can be found:
- For the love of all things good, stop sucking in
- Must I pee when I sneeze?

BUT WHY?
But one thing in health that is sometimes over-looked is the why. Why do we have dysfunctional breathing or what are the causes? There are three main causes of dysfunctional breathing:
1. Developmental Adaptations
During the first year of life, our bodies should go through an ideal developmental pattern that helps create a stabilization system and helps form posture. Two studies (Vjota and Prechtl) both indicated that 69.7-72% of children develop normally while ~30% have abnormal development. (5) 
This is one reason developmental kinesiology and the work of Dynamic Neuromuscular Stabilization (DNS) are important. Both address the ideal developmental pattern that can be adapted as an adult for the 30% of the population that may not have developed a strong stabilizing system in infancy.
2. Physiological / Medical
Hyperinflation of the lungs causes air to get trapped in the lungs. This hyperinfalation, often seen in COPD, asthma or emphysema and severe pneumonia, and congestive heart failure causes the diaphragm to shorten and lose its power and efficiency. (3)
In 2001, Hodges et al stated that the coordinating function between the diaphragm and transverse abdominis are frequently reduced in respiratory disease. (2) When the diaphragm contracts it is unable to properly lift and expand the lower ribcage and instead the lower ribs are pulled inward during inspiration creating what's called a Hoover's sign.
2. Emotional / Psychological
Both psychological and emotional stress can alter the diaphragm’s control. Dysfunctional breathing has been shown to be present in 11% of the normal population, 30% of asthma sufferers and 83% in people suffering from anxiety. (4) It has been reported that voluntary breath modulation accounts for 40% of the variance in positive feelings such as joy and negative feelings such as fear, sadness and anger (7).
In 2001, Umezawa found that breathing modification is the most common self-regulation strategy for relaxation and stress management. (6) Chaitow stated that in “Overbreathing: A Mind-Body Vicious Circle” that over-breathing and anxiety go hand-in-hand as anxiety increases the sympathetic system which causes an increase in breathing rate which leads to excessive carbon dioxide loss and in the end lead to a decreased pain threshold and more anxiety and overbreathing. (9) In 2010, Meuret stated that reducing hyperventilation “has emerged as a potent mediator for reductions in panic symptom severity and treatment success.” (8) Furthermore, studies have shown that conscious control of ones breathing can improve anxiety, depression and panic disorders.
