MORE ON HYPERVENTILATION:
This is excerpted from "HYPERVENTILATION SYNDROME, Breathing Pattern Disorders" by medical researcher Dinah Bradley. I have emphasized some words by putting them in capitals, and words inside square brackets are mine:
"When over-breathing becomes chronic the balance between the oxygen-rich air we breathe in and carbon-dioxide-rich air we breathe out is upset: carbon dioxide levels start to drop... Far from being just a waste gas at the end of the respiratory cycle, carbon dioxide is a powerful governor of many of the body's systems..."
"With chronic over-breathing the normal acid/alkaline (pH) of the tissues is altered. The body becomes more alkaline..."
"The autonomic nervous system, which looks after the body's involuntary functions (for example, heart rate, blood pressure and digestion), is affected too... Low carbon dioxide levels stimulate the sympathetic nervous system... putting the body on red alert... body cells begin to produce lactic acid in an effort to balance pH... Muscle cells become more twitchy, and the SMOOTH MUSCLES OF OUR blood vessels, AIRWAYS and gut TIGHTEN and CONSTRICT in response to lowered carbon dioxide. There is an increased release of histamines, which AGGRAVATES ALLERGIC RESPONSES. " [ Thus causing asthma and/or allergies]
"When carbon dioxide levels are too low oxygen clings to its carriers - the red blood cells - and tissues, especially the brain, become starved of oxygen. [Scientists call this the 'Bohr effect', named for it's discoverer]. The drop in oxygen supply to the brain stimulates the breathing control centre to increase breathing rates and the chronic nature of the hyperventilation is reinforced." [That is, hyperventilation leads to more and stronger hyperventilation. For example, when we feel the beginning of asthma, we naturally try to breathe more deeply; hyperventilation becomes a downward spiral].
STILL NOT CONVINCED THAT ASTHMA IS CAUSED BY OVER-BREATHING ? TO DEMONSTRATE THIS, DR. BUTEYKO USED TO HAVE PATIENTS OPEN THEIR MOUTHS AND BREATHE DEEPLY. THIS WILL GIVE YOU ASTHMA VERY QUICKLY. I DON'T RECOMMEND THAT YOU TRY IT, BUT IF YOU DO, HAVE YOUR PUFFER WITH YOU !
