By analyzing the current sub-health theory and diagnosis means, by using the analysis results as the foundation stone, and by basing the guiding ideology on the conceptions of the functional homeostasis theory and health risk classification, the authors introduced the fuzzy mathematics theory to reconstruct the sub-health theory in order to promote the practical significance and populari-zation of the sub-health theory, and to provide certain methodological reference for the evaluation of sub-health in the future.
