F. M. Alexander
F. M. Alexander made several references to a number of conditions, including asthma, which were relieved or ‘eradicated’ (in the sense of disappearing) as a result of the general level of health from better use and functioning.
Alexander in his writings also blamed the cause of asthma (as well as several other breathing related problems) on the ‘snifﬁng’ and ‘gasping’ modes of breathing,  and the ‘disorganization and consequent strain in the region of the throat’.
See also several references to asthma in MSI.
Alexander provides an asthma case history in UCL.
