Teenagers aged 13–19 who practiced yoga or meditation showed significantly better positive affect, global health, and cognitive health compared to peers who did neither. The study of 425 Indian adolescents found no significant improvement in psychological stress or sleep problems. Lifestyle choices also appeared better among those who practiced yoga or meditation.
A new method called empirical Fourier-Bessel decomposition (EFBD) was used to analyze brain wave patterns from 23 participants listening to the Rudram mantra. After listening, energy in delta, theta, and alpha brain rhythms increased significantly, indicating enhanced relaxation, improved concentration, and reduced anxiety. Brain region-specific analysis showed increased activity in the frontal and temporal regions. The method may help analyze meditation's impact on mental health.
A framework using empirical Fourier–Bessel decomposition and time–frequency representation of EEG signals can classify brain states during Rudram Mantra listening with 77.5% accuracy. The method identifies distinct neural patterns in frontal and temporal brain regions, suggesting that automated monitoring of meditative states is feasible.
