Background and Objective: Health includes various dimensions, one of the most important of which is spiritual health. Although this aspect of health has a long history, it has attracted the attention of doctors and psychologists in the last few decades. One of the effective factors in spiritual health is rationality, which has always been one of the most controversial topics in the history of human thought. This study was done to explain the relationship between health and spirituality.

Methods: This research is of analytical-descriptive type, which was carried out using the library method and using verses, narrations and interpretive sources.

Results: Rationality is not only incompatible with spirituality but also strengthens it. The religion of Islam, which was descended for the development and growth of spiritual health, has always invited people to rationality and has condemned those who do not use reason and thought.

Conclusion: This study shows that rationality has a direct relationship with spirituality and causes the spiritual health of a person.
