The development of the Model of Human Water Balance was prompted by researc
h into dehydration in UK industry. It incorporates basic physiological prin
ciples, recent and current experimental work on the outcomes of fluid balan
ce and heal stress studies, discussion of specific scenarios experienced by
people who work in the heal, and finally compartment analysis, where more
detail of body water compartments is required. The assimilation of theory a
nd empirical data permits the model to be used as a learning tool and as an
aid in practical situations where dehydration is a likely outcome. (C) 200
