The Buteyko Method
The first step to attaining optimal breathing is to breath through your nose and not through your mouth, and this applies to all activities.
Although you breathe to get rid of excess CO2, it's very important that your breathing volume is normal, in order to maintain a certain level of CO2 in your bloodstream. If you're breathing too heavily you lose carbon dioxide, which causes the smooth muscles around your airways to constrict. This creates a negative feedback loop that can lead to chronic hyperventilating and, potentially, exercise-induced asthma.
While you might believe that taking deeper breaths through your mouth allows you to take more oxygen into your body, which should make you feel better, the opposite actually happens. You can test this out by taking five or six big breaths in and out of your mouth. Most people will begin to experience some light-headedness or dizziness.
This occurs because you're eliminating too much carbon dioxide from your bloodstream, which causes your blood vessels to constrict hence lightheadedness. So the heavier you breath, the less oxygen that's actually delivered throughout your body due to lack of carbon dioxide, which causes your blood vessels to constrict. The loss of carbon dioxide caused by heavy breathing also reduces blood flow to your heart, which in some unfortunate cases could lead to cardiac arrest or heart attack.
Nose breathing may indirectly determine arterial oxygenation. Breathing increases arterial oxygen tension. Nitric oxide (NO) is released in the nasal airways in humans. During inspiration through the nose this NO will follow the airstream to the lower airways and the lungs. Nasally derived NO has been shown to increase arterial oxygen tension and reduce pulmonary vascular resistance, thereby acting as an airborne messenger.
Breath Light for increased nitric oxide concentrations. Since NO is continuously released into the nasal airways the concentration will be dependent on the flow rate by which the sample is aspirated. Thus, nasal NO concentrations are higher at lower flow rates. Among the various biological properties of nitric oxide (nasal cavity) are its effects on the growth of various pathogens including bacteria, fungi, and viruses
Importance of breathing both in and out of the nose
To determine if mucosal surface heat and water loss influence the nasal functional response to cold air, we measured nasal resistance by posterior rhinomanometry. During the challenge period, the subjects breathed either in and out of the nose or in through the nose and out through the mouth. No changes in nasal resistance developed when subjects breathed exclusively through the nose.
Improve pulmonary function improves (NO) release which has important functions in a variety of physiological and pathophysiological processes in the body, including vasoregulation, haemostasis, neurotransmission, immunity and respiration. The discovery of surprisingly high concentrations of NO in the nasal airway and paranasal sinuses has important implications for the understanding of airway physiology.
The high NO levels in the nasal and paranasal airways contribute to the first line defence against microorganisms. Furthermore, autoinhalation of nasal NO may improve pulmonary function and other remote physiological processes.
Nitric oxide in the nasal airway: a new dimension in otorhinolaryngology. The surprisingly high concentrations of NO in the nasal airway and paranasal sinuses has important implications for the field of otorhinolaryngology. Nitric oxide inhaled via nasal respiration has been shown to increase oxygen exchange efficiency and increases blood oxygen uptake by 18%, while improving the lungs’ ability to absorb oxygen
