Breathing Retraining: From Sick/Victims to Superhumans

Free Radicals Causes | Oxygen in Cells Is Top Antioxidant

Effects of over breathing on brain oxygen levels and free radical production When thinking about good health and prevention of damage due to free radical production, many modern people are obsessed with foods and diets. Meanwhile, virtually all sick people would still have poor health and abnormally high concentrations of free radicals species (or reactive oxygen species) even if they boost their intake of herbs, supplements and super foods extra rich in antioxidants. Why? This is because they generate free radicals 24/7 and especially during early morning hours due to tissue hypoxia.

You cannot have cancer, or heart disease, or diabetes and normal oxygen levels at the same time. Cell hypoxia is the main cause of free radical generation and oxidative stress. Humans need oxygen in cells, not free unbounded oxygen that can be pumped in the blood using hyperbaric oxygen therapies. (Right oxygen is delivered due to normal oxygen transport.)

Severely and moderately sick people, and most modern people, can consume pounds of antioxidants, drink canisters of super juices and eat tons of best foods, but if their automatic breathing pattern is unchanged, they will suffer from the same symptoms, pains and aches. What is wrong with their breathing?

If you open the Homepage of this site, you will see tables and graphs related to over 100 clinical studies that measured breathing in different groups of people. This solid scientific evidence tell us a clear story about causes of free radicals and poor health in modern people, as well as people with chronic diseases.

Average minute ventilation in modern "normal subjects" is about 12 L/min and they have only about 20-25 for the body-oxygen test (see links below). Therefore, people generate free radicals "naturally". Let us now prove that abnormal breathing is the most powerful source of free radicals and oxidative stress in modern, especially sick, people.

CO2 and Cellular O2 are Best Natural Antioxidants

Carbon dioxide molecule: free radical fighter Normal arterial levels of CO2 have antioxidant properties. Indeed, a group of Russian microbiologists discovered that "CO2 at a tension close to that observed in the blood (37.0 mm Hg) and high tensions (60 or 146 mm Hg) is a potent inhibitor of generation of the active oxygen forms (free radicals) by the cells and mitochondria of the human and tissues" (Kogan et al, 1997). They suggested several independent mechanisms involving inhibition of the NADPH-oxidase activity (Kogan et al, 1997; Kogan et al, 1996), better coordination of oxidation and phosphorylation and increased the phosphorylation velocity in liver mitochondria (Boljevic et al, 1996).

Czech scientists from the Department of Medical Chemistry and Biochemistry of the Faculty of Medicine (Charles University, Center for Experimental Cardiovascular Research, Prague) published an article in the Physiological Research Journal with the title "The role of carbon dioxide in free radical reactions of the organism" (Vesel & Wilhelm, 2002). They discovered several mechanisms to explain the protective antioxidant role of CO2 against free radical damage (see the abstract and the link to the study below).

This is sensible since hypocapnia or over breathing reduces oxygen levels in body cells (see image of the brain).

Ineffective breathing: the key cause of free radical damage

Mouth breathing peopleDozens of studies have shown that modern "normal subjects" breathe about 12 L/min at rest, while the medical norm is only 6 L/min.  As result, blood CO2 levels is less than normal. Arterial hypocapnia (CO2 deficiency) causes tissue hypoxia that trigger numerous pathological effects (see links with medical studies below).

There are additional adverse biochemical effects related to mouth breathing and chest breathing that also promote free radical damage and oxidative stress.

For most modern people, there is a certain time of the day when they have lowest levels of oxygen in the brain and body cells. This is also the time when people generate most free radicals.

Sleep and free radical generation

Old man sleeping in hospital bed Most people feel worst or most miserable in the morning. Furthermore, as mentioned above, severely sick, critically ill (due to heart attacks, seizures, acute asthma, strokes, etc.) and hospitalized patients are most likely to have acute episodes or even die during early morning hours (see medical research on Web page Sleep Heavy Breathing Effect). The key reason for all these abnormalities is a low body oxygen level due to overbreathing with contributions of chest/mouth breathing. What are the effects? Hypoxic cells switch to anaerobic respiration and start producing lactic acid and other incompletely oxidized chemicals or free radicals causing cellular stress and intensifying respiration.

While many people are concerned with free radicals in foods, water and air, generally sick and severely people do not eat or drink anything during or just before night sleep. How do they cause oxidative stress then? They get free radicals and free radical damage due to their low oxygen levels in the body caused by heavy breathing and low levels of CO2 in the lungs.

MDs smiling Over 175 medical doctors practicing the Buteyko breathing technique suggested that there are 2 thresholds for the body-oxygen test in relation to free radical generation:
- less than 20 s for the body-oxygen test (moderate degrees of chronic diseases)
- less than 10 s (severe forms of chronic diseases).

Therefore, taking care about light and easy breathing 24/7 (and high body oxygen levels), especially during early morning hours, is a much smarter step to prevent free radical damage and increase body antioxidant defenses than to worry about diets, "natural" supplements and pills.

Carbon dioxide interacts both with reactive nitrogen species and reactive oxygen species. In the presence of superoxide, NO reacts to form peroxynitrite that reacts with CO2 to give nitrosoperoxycarbonate. This compound rearranges to nitrocarbonate which is prone to further reactions. In an aqueous environment, the most probable reaction is hydrolysis producing carbonate and nitrate. Thus the net effect of CO2 is scavenging of peroxynitrite and prevention of nitration and oxidative damage. However, in a nonpolar environment of membranes, nitrocarbonate undergoes other reactions leading to nitration of proteins and oxidative damage. When NO reacts with oxygen in the absence of superoxide, a nitrating species N2O3 is formed. CO2 interacts with N2O3 to produce a nitrosyl compound that, under physiological pH, is hydrolyzed to nitrous and carbonic acid. In this way, CO2 also prevents nitration reactions. CO2 protects superoxide dismutase against oxidative damage induced by hydrogen peroxide. However, in this reaction carbonate radicals are formed which can propagate the oxidative damage. It was found that hypercapnia in vivo protects against the damaging effects of ischemia or hypoxia. Several mechanisms have been suggested to explain the protective role of CO2 in vivo. The most significant appears to be stabilization of the iron-transferrin complex which prevents the involvement of iron ions in the initiation of free radical reactions.

Abstract
Studies were carried out on blood phagocytes and alveolar macrophages of 96 humans, on the cells of the viscera and tissue phagocytes (liver, brain, myocardium, lungs, kidneys, stomach, and skeletal muscle), and liver mitochondria of 186 random bred white mice. Generation of the active oxygen forms was determined using different methods after direct effect of CO2 on the cells and biopsies and indirect effect of CO2 on the integral organism. The results obtained suggest that CO2 at a tension close to that observed in the blood (37.0 mm Hg) and high tensions (60 or 146 mm Hg) is a potent inhibitor of generation of the active oxygen forms (free radicals) by the cells and mitochondria of the human and tissues. The mechanism of CO2 effect appears to be realized, partially, through inhibition of the NADPH-oxidase activity. The results are important for deciphering of a paradox of evolution, life preservation upon appearance of oxygen in the atmosphere and succession of anaerobiosis by aerobiosis, and elucidation of some other problems of biology and medicine, as well as analysis of the global bioecological problem, such as ever increasing CO2 content in the atmosphere.

Abstract
The study was carried out on blood phagocytes and alveolar macrophages of 96 persons, cells of inner organs and tissue phagocytes (liver, brain, myocardium, lungs, kidneys, stomach, skeletal muscles), as well as on mitochondria of the liver of 186 non-linear white mice. Generation of active oxygen forms (AOF) was evaluated by various methods with CO2 directly affecting the cells and bioptates and indirectly the whole organism. The results show that CO2 with tension close to that of the blood (37.0 mm Hg) and at higher tensions (60 and 146 mm Hg) is a powerful inhibitor of AOF generation by human and animal cells, as well as by liver mitochondria of mice. The data obtained allow to explain, in terms of AOF role, a number of physiological and pathophysiological (medical) CO2 effects.

Abstract
Carbon dioxide (CO2) influence in generation of active oxygen forms (AOF) in human mononuclear cells (blood phagocytes and alveolar macrophages) and animal cells (tissue phagocytes, parenchymal and interstitial cells of liver, kidney, lung, brain and stomach) was investigated. The AOF generation was examined by the methods of chemiluminiscence (CL) using luminol, lucigenin and NBT (nitro blue tetrazolium) reaction. It was established that CO2 in concentrations similar to those in blood (5.1%, pCO2 37.5 mmHg) and at high concentrations (8.2%, pCO2 60 mmHg; 20%, pCO2 146 mmHg) showed pronounced inhibitory effect on the AOF generation in all the studied cells (usually reducing it 2 to 4 times). Those results were obtained not only after the direct contact of isolated cells with CO2, but also after the whole body exposure to CO2. Besides, it was established that venous blood gas mixture (CO2 - 45 mmHg, +O2 - 39 mmHg, + N2 - 646 mmHg) inhibited the AOF generation in cited cells more than the arterial blood gas mixture (CO2 - 40 mmHg, + O2 - 95 mmHg, + N2 - 595 mmHg). Carbon dioxide action mechanism was developed partially through the inhibition of the OAF generation in mitochondria and through deceleration of NADPH oxidative activity. Finally, it was established that CO2 led to the better coordination of oxidation and phosphorylation and increased the phosphorylation velocity in liver mitochondria. The results clearly confirmed the general property of CO2 to inhibit significantly the AOF generation in all the cell types. This favors the new explanation of the well-known evolutionary paradox: the Earth life and organisms preservation when the oxygen, that shows toxic effects on the cells through the AOF, occurs in the atmosphere. The results can also be used to explain in a new way the vasodilating effect of CO2 and the favorable hypercapnotherapy influence on the course of some bronchial asthma forms. The results are probably significant for the analysis of important bio-ecological problem, such as the increase of CO2 concentration in the atmosphere and its effect on the humans and animals.

Abstract
30 bronchial asthma (BA) patients and 15 donors were exposed to 8.3% and 20.8% CO2 to bring out leukocytes sensitivity to CO2 by generation of active oxygen (AO) in bronchial asthma. CO2 effects on leukocyte AO generation were defined by luminol-dependent chemiluminescence (CL) before and after the exposure to CO2. It was found that in healthy subjects 8.3% and 20.8% CO2 noticeably inhibits leukocyte CL. However, in 70% of asthmatics with BA exacerbation leukocyte sensitivity to CO2 inhibition diminished. This was normal in 30% of BA patients. With BA aggravation, leukocyte sensitivity to CO2 tended to a decrease. Remission brought a complete or partial recovery of the above sensitivity. Thus, on the one hand, CO2 is involved in BA pathogenesis in terms of its inhibitory effect on AO generation by leukocytes; on the other hand, only in 30% of BA patients high CO2 concentrations as a treatment may be justified.

[Comparative study of the effect of carbon dioxide on the generation of active forms of oxygen by leukocytes in health and in bronchial asthma]
[Article in Russian]

Abstract
The study was conducted by using leukocytes isolated from 74 apparently healthy donors and 60 patients with bronchial asthma. The generation of active oxygen forms was determined by luminolo- and lucigenin-dependent chemiluminescence techniques and NTC-reaction. The findings suggest that at the tension close to the blood tension of 37.5 mm Hg and the high tension of 146 mm Hg is a powerful natural inhibitor of leukocytic generation of active oxygen forms. At an exacerbation, the inhibitory effect of carbon dioxide on the leukocytic generation of active oxygen forms decreased in most (70%) patients with bronchial asthma, which potentiates the free radical mechanism of development of bronchial asthma. It may be held that the literature-described use of carbon dioxide for the treatment of bronchial asthma is justifiable only in a lower proportion of patients who have preserved a high sensitivity to the inhibitory effect of carbon dioxide on the generation of active oxygen forms.
