Okay this isn’t a sorority house chant or the name of the next space shuttle that is flying to Mars. These, my friend, are your brainwaves! Fascinating… I know. Allow me to explain. It is very interesting to learn that different brainwaves correspond with how we feel at any given moment. With slower brainwaves we can feel tired, slow, sluggish, or dreamy. Higher frequencies are when we feel wired, or hyper-alert.
A brainwave is a combination of electrical activity in your brain and is known as a brainwave frequency or pattern. These patterns run in cycles, which mean that they are being repeated at an extremely fast rate as they vibrate through the neurons in the brain. Brainwaves are measure in Hz.
We have five (Beta, Alpha, Theta, Delta and Gamma), and each brainwave frequency has its own set of characteristics representing a specific level of brain activity.
Delta brainwaves (0.2 – 3Hz) are the slowest and are generated in deepest meditation and dreamless sleep.
Beta brainwaves (12 – 27Hz) are associated with normal waking consciousness and a heightened state of alertness. This is where you spend most of your waking hours. These brain waves are important for effective functioning throughout the day, they also can translate into stress and anxiety.
Alpha brainwaves (8 – 12Hz) are alive in deep relaxation and usually when the eyes are closed, when you’re slipping into a nice daydream or light meditation. Alpha is ‘the power of now’, being here, in the present. (Less distracted by that bill you have to pay in two months or what you need to buy for dinner next Tuesday!)
Gamma brainwaves (27 Hz) are the fastest of brain waves (high frequency, like a flute). These frequencies relate to expanded consciousness and feelings of love.
Theta brainwaves (3 – 8Hz) occur most often in sleep but are also dominant in the deep meditation. It acts as our gateway to learning and memory.
The most powerful brainwaves for the human brain are below 20Hz. Binaural music work by playing two separate tones with a specific frequency in each ear. The effect is a perceived tone of a very low Hz (9 Hz for example, which is a very low Alpha state linked to enhanced memory.)
It is possible for these brainwaves to cause problems. Over stimulation can cause anxiety, stress or problems with sleep. When certain brainwaves are under stimulated, this can lead to some forms of depression and general fatigue.
With binaural music meditation, the main objective is to create balance by stimulating certain brainwave patterns into a more natural state. It is a very effective way to relax when over worked, or to gain a boost of energy when feeling unnaturally tired. When these brainwaves are out of balance it also effects our mood, so practicing meditation with brainwave entrainment is a great way to stay centered and focused in a positive energy.
