4-C. How to stop coughing, sneezing, sighing, yawning, hiccups, sniffing fast and naturally
Learning the Buteyko method by modules
Here is another fast natural application of the Buteyko breathing method. In a recent study (Giardino et al, 2007) done in the Departments of Radiology, Psychiatry and Bioengineering, University of Washington, School of Medicine, Seattle, American doctors and MDs revealed that sighing is a "diagnostic feature of several anxiety disorders... Sustained hyperventilation causes large reductions in global CBF, but even a single sigh can produce a 1–3 mmHg decrease in PCO2, enough to decrease CBF".
Indeed, during one sigh we blow out up to 2 l of air and it takes about 3-5 minutes to restore blood gases, even if the person breathes normally after this sigh. Hence, sighing every 3-5 minutes means chronic hyperventilation. How to prevent it?
Coughing for many minutes is annoying and a health hazard. It not only washes out CO2, reduces oxygenation, but also resets the breathing centre to the state of chronic hyperventilation. Moreover, during normal breathing at rest the air travels though nasal cavities at a speed of 8 km/h. When we cough, the air rushes out at 120-160 km/h due to a large pressure gradient. Such disturbance can easily rupture alveoli, tiny air sacs of our lungs due to their fragility.
