摘要

Objectives

Mind–body practices, such as meditation, have been shown to enhance mental well-being. Research shows that meditation influences brain function, with neurophysiological studies highlighting changes in alpha and theta frequency bands. However, when EEG changes begin after starting meditation and how they evolve over meditation state remain unknown.

Method

To address this, we analyzed 128-channel EEG data during breath-watching meditation (10 min), a focused-attention practice, in meditation-naïve controls (n = 28), novice meditators (n = 33), and advanced meditators (n = 42). Meditators belonged to the Isha Yoga tradition. We examined temporal dynamics in EEG power across different frequency bands (delta: 0.5 – 4 Hz; theta: 4 – 8 Hz; theta-alpha: 6 – 10 Hz; alpha: 8 – 12 Hz; beta1: 13 – 20 Hz; beta2: 20 – 30 Hz; and gamma1: 30 – 40 Hz) and groups. Threshold-Free Cluster Enhancement (TFCE)-based permutation statistics were used for statistical comparisons across multichannel EEG data.

Results

All groups showed significant EEG changes—an increase in alpha, theta, and beta1 power and a decrease in delta and gamma1 power—emerging around 2–3 min after starting meditation and peaking between 7- and 10-min. Advanced meditators exhibited consistently higher theta and theta-alpha power at all time points.

Conclusions

Our study suggests that the brain's response to meditation can be rapid and varies with practitioners’ experience, potentially influencing cognitive and emotional processing in significant ways. Since meditation retreats may not be feasible for many individuals, brief meditation practices of seven min or more—delivered through digital platforms—could offer accessible, effective, and scalable solutions for improving mental well-being.
