What
are Brainwaves?
Every moment of
your life your brain is active. It is pulsing with electrical impulses;
you heard that right, electricity! The electricity or electrical
current generated by the brain can be measured with an electroencephalogram
(EEG), which measures the frequency of the electrical current. This
frequency or speed of the brainwave is measured in Hertz(HZ).
Now here is the
really cool part. These frequencies can be associated with your
state of mind at any particular moment. This means that your state
of mind, for example being relaxed, frightened, or sleepy...can
be "seen" in your brainwave frequencies. The speed of
the frequency allows us to categorize our brainwaves into four broad
categories.
What
are the different brainwave patterns?
There are four
common brainwave patterns that have been well researched and documented.
They are:
Beta
waves
- 14Hz to 20Hz. Beta waves are associated with normal waking consciousness.
They are present when you are focused on activities in the outside
world.
Alpha
waves
- 8Hz to 13Hz. Alpha waves are likened to a light meditation. They
are prevalent when you daydream. They will become stronger when
your eyes are closed. While the brain is in an alpha state, the
mind and body can be directed to make changes and create new positive
habits - the state of hypnosis.
Theta
waves - 4Hz to 7Hz. Theta waves occur during heightened
states of creativity and are found with a deep meditative state.
Delta
waves
- .5Hz to 3Hz. Delta waves are found in a deep sleep state or unconsciousness.
Also, Delta waves are common in very deep meditation.
Focus,
creativity and concentration - the alpha connection
A predominance
of Alpha waves in the brain is associated with accelerated learning,
focus and enhanced creativity. When you are focus on something,
there is a predominance of Alpha waves. No matter what your profession
or hobby, these attributes will increase your productivity and enhance
your experience.
Finding
the higher self - the theta connection
A deep meditative
state is true bliss. Increase your Theta waves and you are on your
way to this state. In the Theta state you can lose your attachment
to the physical body. You will feel a deep sense of physical relaxation.
This disconnect of mind and body allows you to focus on the inner
you, the higher self. This is the ideal state to begin your journey
into meditation.
Sleep
and more - the delta connection
A Delta state
has long been associated with sleep. If you have trouble sleeping,
the CDs targeting this range will help immensely. Having a CD that
targets the Delta brainwaves will allow you to enter a deep sleep
state easily. It will be time to say good-bye to insomnia!
Recently there
has also been some research that suggests that an even deeper meditative
state can occur during predominate Delta wave activity. As you gain
experience and comfort with meditation, you may want to try reaching
a Delta state during meditation.
