Modern people experience mental and physical stresses directly or indirectly from their surroundings. And stress symptoms are known to be the cause of all illnesses. Therefore, if people can identify stress symptoms and sub health conditions in advance and make appropriate action plans, they can lead a better mental and physical life. In this paper, a statistical analysis was performed on a particular group with data obtained from the questionnaire on the degree of stress symptoms and sub health conditions. Statistical analysis shows that stress symptoms are related to all 10 sub health conditions. Furthermore, the results of the decision tree analysis showed that 97.4% of the respondents with poor immune system sub health are suffering from stress symptoms.
