Why did you not tell us that shallow breathing was preferable? [As it is with the Buteyko method.]
BECAUSE it is not - at least, not to be prescribed to everyone. That is why. The equation is:
- The metabolic rate determines volume = lesser capacity in lung - inhale - expanded lung - exhale, BUT the ratio of inhale to exhale is consistent, and the time of metabolic consideration is the same.
The point missed is that: breath in - 1,2,3, breath out - 1,2,3 (over 3 seconds). Breath in - 1,2,3,4,5, and breath out - 1,2,3,4,5, (over 5 seconds). The asthmatic has breath in 1,2,3,4,5, breath out 1,2,3,4,5, over 3 seconds, for example.
It relates specifically to speed and metabolic rate rather than volume - but the volume reduction can and will 'even' the assimilative timing. As agreed, all of the lung is penetrated and used.
