Since the beginning of the mankind religion and religiousness hold an important role in the life of the most, therefore it is very important to know the basic facts in this aspect of human life. Especially for those who are working with people in need. Numerous empirical researchwhich had been taken in the last few decades show the correlation between religiousness and health. Religion as a value system has significant impact on the health of an individual and it's been observed, more and more, from the cultural aspect along with sociology as a relevant discipline. In this study we will direct our aim on the relation between religiousness (engagement of the individual) and health (physical and mental). We had take in concern that religiousness has been considered as an existential need of an individual, and we wanted to research if religiousness has an impact on the health benefits. Therefore, the aim of this study was to determine an impact and connection between religiousness of an individual and their self influence on their own health. Here, we want to determine if religiousness has an impact on the recovery of an individual with health issue. Religion that prevails among this sample is which respondents have adopted in their primary socialization (partly as their family tradition and partly as a custom of the area they have grown up and been living). For this purpose we did the research on the representative sample of theadult inhabitants of the Dubrovnik-neretva county in Croatia. As an indicator of the religiousness we have used religious self identification and the frequency of the personal prayers, where as an indicator of the religious impact on the health we have used positive effect of the personal prayers on the health of an individual and the self-assessment of the prayers on the health of an individual. The hypothesis of this study has been tested using the logistic and ordinal analysis. In the end, we have determined the correlation between religiousness and health, however the small number of the indicators and low proportion of the explained variation don't allow us to make a final conclusion about the nature of that correlation (is the correlation positive, negative or both).
