Chanting the OM mantra for 30 minutes produces significant changes in the delta brainwave band, which is associated with deep sleep, suggesting that OM meditation induces a deep-sleep-like state. Twenty-three novice meditators had their EEG signals recorded before and after chanting. Using stationary wavelet transform to extract five frequency bands and an SVM classifier with a radial basis kernel, the delta band showed the most notable shifts. This indicates that even brief OM mantra practice can alter brain activity toward a restful state.
