Summary
During meditation, our hearts reveal an unexpected pattern: while short-term heartbeats remain rhythmic, the usual long-term patterns become less predictable. Using advanced data analysis, researchers found that deep mental relaxation actually simplifies our heart's complex rhythms, suggesting meditation creates a unique physiological state distinct from normal rest.
Abstract
The average wavelet coefficient method is applied to investigate the scaling features of heart rate variability during meditation, a state of induced mental relaxation. While periodicity dominates the behavior of the heart rate time series at short intervals, the meditation induced correlations in the signal become significantly weaker at longer time scales. Further study of these correlations by means of an entropy analysis in the natural time domain reveals that the induced mental relaxation introduces substantial loss of complexity at larger scales, which indicates a change in the physiological mechanisms involved.
