The brain is made up of billions of brain cells called neurons that are constantly working, creating energy by communicating through electrical signals. The electrical impulses created by your brain can be measured by an EEG (electroencephalogrophy) machine as a wavelength that is emitted from your head. Through this research, scientist have discovered the different frequencies of the brain.
The 4 most common brainwave frequencies are beta, alpha, theta, and delta. Now, each of these brainwaves serves a specific function. Brainwaves are measured in hertz, or cycles per second and, generally speaking, the slower the wave the more calm and relaxed your brain is. The higher the frequency the more active your brain is. However, a more active brain is not always a good thing. The higher frequencies can also be associated with stress, anxiety, and agitation. Lets take a closer look at these brainwaves and their functions starting with the more active, higher frequency down to the lowest.
Beta: 14 – 40 Hz
Beta is the most common wave length associated with normal waking functions. Generally speaking, when you are awake and your eyes are open, your brain is operating in the beta frequency. The lower beta range is when you have logical thinking, reasoning, and critical thinking.
On the other hand, the higher state of beta is associated with stress, anxiety, and agitation. These symptoms are common when your brainwaves are scattered and heightened.
The good news is that when you listen to brainwave entrainment, you are actually synchronizing all of your brain activity to the beta frequency (usually the lower range of beta), which can sharpen your focus and logical thinking.
Alpha: 7.5 – 13 Hz
Alpha is often described as the daydream state, the state right before falling asleep or right after waking up. It is the state of deep relaxation and light meditation. This is the state to try things like visualization, enhancing creativity, and improving intuition.
This is the best range people who are new to brainwave entrainment. It will get you totally relaxed and optimize the ability to program your subconscious mind for success. The closer you get to the bottom of alpha (closer to theta), the easier it is to communicate with your subconscious.
Theta: 4 – 7.5 Hz
Theta is the sleep or dream state. This is the ultimate deep meditation state. It is hard to stay awake during the theta state for the inexperienced meditator. But if you are willing to practice, theta is the state between awake and deep sleep where you can experience a deep spiritual connection and unity with the universe, inner self, God, or whatever inner guidance system suits you.
The state between alpha and theta is the optimal range for intense meditation and visualization, where you can consciously create your reality. This is, of course, if you have the patience to practice. Even with brainwave entrainment, staying awake during this state takes some practice, but will provide the most rewards.
Delta: 0.1 – 4 Hz
This is the deep sleep state, the lowest of brainwave activity. This is associated with dreamless sleep. This is the true state of your unconscious mind. Deep sleep is liked with healing and regeneration, hence the need for this state when sick or injured.
Because delta is the state where consciousness is completely gone and the unconscious mind is left wide open for influence, this is the perfect state to introduce dream programming.
Dream programming is the process of introducing recorded affirmations in the delta state that change behaviors through programing automatic response triggers (ART) to the subconscious. This can literally reprogram your mind to quit addicting habits, overcome stress, lose weight, change limiting beliefs about love or money, and even improve intuition and luck. Amazing stuff! Hypnosis Bootcamp has a great collection of dream programming audios with brainwave entrainment inductions.
Altering your brainwave frequencies:
Now, keep in mind that during normal waking state, your brain doesn’t necessarily work on one single wavelength. The brain is fluctuating between all of these different waves and actually producing multiple frequencies at the same time.
When you listen to brainwave entrainment, you are concentrating your brain to primarily operate on one specific wavelength. This is called brainwave synchronization. Below is an EEG graph of the brain in a normal waking state and the brain after listening to brain entrainment. Notice how the brainwaves before are scattered and not not operating at peak frequency levels. After brain entrainment, the brainwaves are targeted and extremely strong. (This EEG graph was taken from a person using the Brain Evolution System.)
