The Effect of Sound of the Quran on Hygiene, Mental Health, and Physiological Functions: A Systematic Review

Sounds or voices influence the soul and the body of all creatures from humans to flora and fauna. The harmonious song of the Holy Quran and its agreeable sound is a pleasant mystical music. Basically, the most magnificent miraculous dimension of the Quran is its harmony with sweet melodies and great songs. Furthermore, one of the aspects of the miracle of the Quran, which has been neglected, is hidden in the sound of the Quran. In this systematic review, we investigated the Quranic sound and its effects on hygiene, mental health and physiological functions. Information databases that we searched included: SID, Magiran, Irandoc, Noormags, Iran Medex, Cochrane, Google scholar, Scopus. Keywords (English/Persian) used for search were: Sound, Voice, Quran, Holy book, Physiologic, Mental health, Hygiene and a combination of these were used with high degree of sensitivity. All ethical issues were observed in this study and the authors of the article have not reported any conflicts of interest. In our quest, we found 471 articles. Following our inclusion and exclusion criteria, 40 articles made it to the final analysis of the study. Most of the articles were omitted due to lack of information about the miracle of sound of the Quran and the lack of overlap between the two categories of the sound of Quran and mental health and physiological functions. The results showed that the sound of the Quran can significantly play a role in reducing the amount of anxiety, mental health, pain intensity, improvement of patients' health, signs and physiological function of different tissues of the body, immune system, and patients' levels of satisfaction.
