Homeostasis: a framework for integrating the life sciences

Nurse education curricula continue to emphasize the holistic nature of health and ill-health. As a concept, holism recognizes that the interactions between a person and his/her environment are significant factors in shaping the individual, and important determinants of wellbeing. Psychosocial interactions as a basis for health now figure prominently in nursing curricula. In contrast, the applied biological sciences have increasingly become marginalized, yet knowledge of the biological construct of the individual, and an understanding of how it is influenced by psychosocial interactions, are also necessary if holistic care is the aim. Nursing models attempt to reinforce holistic principles, but the integrative nature of health and illness needs to be established before their application. This article proposes that the concept of homeostasis, and its relationship to systems theory, provides a workable framework for teaching the basis of health, and so forms a foundation for the application of nursing theory and nursing models.
