Abstract
Objectives: This study investigated the effect of Muslim prayer (salat) on the a relative power (RPa) of
electroencephalography (EEG) and autonomic nervous activity and the relationship between them by using
spectral analysis of EEG and heart rate variability (HRV).
Methods: Thirty healthy Muslim men participated in the study. Their electrocardiograms and EEGs were
continuously recorded before, during, and after salat practice with a computer-based data acquisition system
(MP150, BIOPAC Systems Inc., Camino Goleta, California). Power spectral analysis was conducted to extract
the RPa and HRV components.
Results: During salat, a significant increase ( p < .05) was observed in the mean RPa in the occipital and parietal
regions and in the normalized unit of high-frequency (nuHF) power of HRV (as a parasympathetic index).
Meanwhile, the normalized unit of low-frequency (nuLF) power and LF/HF of HRV (as sympathetic indices)
decreased according to HRV analyses. RPa showed a significant positive correlation in the occipital and parietal
electrodes with nuHF and significant negative correlations with nuLF and LF/HF.
Conclusions: During salat, parasympathetic activity increased and sympathetic activity decreased. Therefore,
regular salat practices may help promote relaxation, minimize anxiety, and reduce cardiovascular risk.
