Brain waves explained - Alpha, Beta, Gamma, Delta & Theta (Part-2)
Brain Waves Explained Scientific evidence—meditation, alpha & theta— Multiple controlled studies and reviews show consistent EEG changes during and after meditation: Mindfulness and many meditation practices are associated with increases in alpha power (relaxed wakefulness) and changes in theta, though the direction depends on meditation type and depth. Experienced meditators can show different alpha/theta patterns from novices. Meditation reliably alters alpha/theta balance, but which band increases depends on technique, experience level and whether the practice is more concentrative or open-monitoring. Can we deliberately increase alpha or theta? Evidence-based methods - 1. Mindfulness & focused-attention meditation (good evidence) - Effect —Often increases alpha (calm alertness) and can increase theta during deep inward focus. How to practice (simple) - 10–30 min daily; focus on breath for 10 minutes, then expand to body-scan/open...
