Background: The purpose of this study was to identify the most suitable time periods for the treatment of diseases by considering human biological clocks and consider treatment recommendations in terms of such factors and how they influence human health and treatment. Specifically, we address how planetary rays impact specific time zones. Methods: Reference sources come from the classical period in Islamic history where studies were done in the fields of medicine and astronomy. During a certain portion of the classical period, Islamic medical scientists were also at the same time interested in astronomy. Thus, they evaluated both astronomy and medical data in the course of treatment. This study has no connection with astrology.
Results: During the classical period of Islamic history, medical studies put forth that people are affected by environmental factors arising from the moon and the sun. Additionally, humans are at the same time affected by planetary movement in the solar system. To obtain an understanding of how such environmental factors influence our health, it is important to determine the operational mode and timing of hormones in relation to our biological clock, which manages bodily functions and timing of such functions in humans. Thus, the relationship between the moon, sun, and humans must be understood correctly. This study utilized modern studies of medicine and astronomy with data from classical astronomy and medicine to better understand such relationships. This approach is distinct and unrelated to astrology.
Conclusion: The thesis in our study offers theoretical information for future research. We believe that the data here will be a key resource for subsequent experimentbased studies.
