Heart–brain Rhythmic Synchronization during Meditation: A Nonlinear Signal Analysis
International Journal of Yoga May 1, 2023 Shrivastava Anurag, B. K. Singh, D. Krishna et al.
The electrical activity of the heart and brain becomes more synchronized during heartfulness meditation, especially among long-term practitioners. In a study of 45 healthy volunteers divided into long-term meditators, short-term meditators, and nonmeditators, detrended fluctuation analysis of EEG and ECG signals showed that values declined during meditation and transmission states compared to before and after. Long-term meditators showed significant changes across all states and a positive correlation between heart and brain activity, while short-term and nonmeditators showed no significant correlations. Regular meditation practice may promote physiological synchrony between cardiac and neural behavior, supporting mental and emotional stability.
