The Effect of the Holy Quran Voice on Improving Sleep Quality of Patients after Cardiac Surgery

Many patients have trouble sleeping after heart surgeries. The aim of this study was to investigate the effect of the Holy Quran Voice on improving the quality of patients' sleep after cardiac surgery.

This randomized clinical trial was conducted from December to March 2012 on 108 patients undergoing elective open heart surgery in the Golestan Hospital of Ahvaz. The data collection tools included demographic data, clinical variables and the Richard Campbell Sleep Questionnaire. In the intervention group, the sound of the Holy Quran was broadcasted twice a day each lasting for 10 minutes. The sleep quality was assessed every day.

Due to the lack of sphericity, the Greenhouse-Geisser correction showed that the use of the Holy Quran voice was effective on the sleep quality of the patients (F = 12.451 and P <0.001).

According to the findings of this study, the use of the Holy Quran voice increased the quality of sleep after cardiac surgery.
