1) Beta (14-40Hz) –Beta brain waves are associated with normal waking consciousness and a heightened state of alertness, logic and critical reasoning. While Beta brain waves are important for effective functioning throughout the day, they also can translate into stress, anxiety and restlessness.
2) Alpha (7.5-14Hz) Alpha brain waves are present in deep relaxation and usually when the
eyes are closed, when you’re slipping into a lovely daydream or during
light meditation. It is an optimal time to program the mind for success
and it also heightens your imagination, visualization, memory, learning
3) Theta (4-7.5Hz) Theta brain waves are present during deep meditation and light sleep,
including the all-important REM dream state. It is the realm of your
subconsciousness and only experienced momentarily as you drift off to
sleep from Alpha and wake from deep sleep (from Delta).
4) Delta (0.5-4Hz) – The Deep Sleep Wave
The Delta frequency is the slowest of the frequencies and is
experienced in deep, dreamless sleep and in very deep, transcendental
meditation where awareness is fully detached. It’s linked with deep healing and regeneration.
5) Gamma (above 40Hz) – The Insight Wave
This range is the most recently discovered and is the fastest frequency at above 40Hz. While little is known about this state of mind, initial research shows Gamma waves are associated with bursts of insight and high-level information processing.
