Effect of Ramadan fasting on heart rate variability as a measure of cardiac stress in a Lebanese cohort

Background Intermittent fasting is an annual religious practice of Muslims worldwide, which affects the physiology of the body due to lifestyle alterations. This study aimed to evaluate the effect of Ramadan fasting on the HRV, an indirect measure of cardiac sympathetic stress. Methods This study in...

description Background Intermittent fasting is an annual religious practice of Muslims worldwide, which affects the physiology of the body due to lifestyle alterations. This study aimed to evaluate the effect of Ramadan fasting on the HRV, an indirect measure of cardiac sympathetic stress. Methods This study included 80 healthy Lebanese females (aged 18–25 years old) monitored for 24 h when following normal routine; 38 and 42 females were enrolled before and during Ramadan, respectively. Results Our results reveal no effect of fasting on HRV; there was insignificant change in HRV between the first and last weeks of Ramadan ( P  > 0.05). Morning fasting was significantly the least stressful period (lowest HR, P
