Recently, with the development of advanced medical technology and the introduction of most advanced medical equipments, life expectancy increases accordingly. Many people want to live long-lived in health. Therefore, if it is possible to pre-diagnose the sub-health condition and formulate an appropriate treatment plan, we can prevent the disease and reduce social expenditure costs. In this study, we statistically analyzed the data in responding to each questionnaire for healthy biorhythm and sub-health among targeted members of a specific group. The analysis for the effects of healthy biorhythm to male and female showed that there was a significant difference between male and female. In the analysis of the effects of the conditions of healthy biorhythm to the 10 sub-health indicators, the significant effects of good and bad condition has been observed. The results of the decision tree analysis showed that all the respondents with poor hormone and urological sub-health status have bad healthy biorhythms. In summary, in this paper we have shown that it may be possible to improve the sub-health condition and prevent disease in advance if the healthy biorhythm is well controlled.
