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 brain can be measured with an electroencephalogram (EEG), which measures frequency of electrical current. This frequency or speed of brainwave is measured in Hertz(HZ).
Now here is 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 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 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.
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.
