Scientific Information on Brainwaves

For many years scientists have been using electroencephalogram (EEG) machines to measure brainwave activity. From this research scientists have determined that our mental states are directly related to the brainwave frequencies we experience.

These brainwave frequencies have been divided into five major groupings, namely:

Delta (0.1 Hz to 4 Hz)

Delta brainwave frequencies are typically present in our brains when we are in deep sleep. Delta frequencies are also crucial for rejuvenating our physical body, and for physical healing.

Theta (4 Hz to 7 Hz)

Theta brainwave frequencies typically occur when first waking up in the morning and during daydreaming. Theta frequencies are useful for processing mental information, inspiring creativity, and developing intuition.

Alpha (7 Hz to 12 Hz)

Alpha brainwaves typically occur when we are alert but relaxed. Alpha frequencies are very good for mental processing, and increasing intelligence. They are heavily used in the accelerated learning process for this reason. Some people have successfully raised their IQs using certain alpha frequencies.

Beta (12 Hz to 30 Hz)

Beta brainwave frequencies, typically occur when we are awake and alert. They are stimulated by drugs such as caffeine, which is why sports people often use caffeine as a supplement to increase physical energy. When beta frequencies exceed 18Hz we can start to feel jumpy and edgy. As the frequencies increase, we can start to become angry or panicky. Stress typically increases beta brainwave frequencies.

Gamma (30+ Hz)

Gamma brainwave frequencies typically occur under conditions of extreme duress, such as shock or serious physical injury. A highly stressed person may have gamma brainwaves present if he or she isin a state of “freaking out” or is experiencing a breakdown. Strangely though, certain Gamma frequencies have been linked with enhanced concentration and memory improvement.
