Brainwaves...



Did you know you have five different brainwaves.  Yes, our brains have five brainwave frequencies and each one has a distinct electrical pattern that operates even when you're asleep.
 
Using an EEG (electroencephalograph is a device which tracks your neuro activity or brainwaves)  to record these five different channels, each frequency is measured in cycles per second (Hz) and has its own set of characteristics representing a specific level of brain activity.  To understand the power of hypnosis let’s look at these brain waves and understand what they mean.

Our brains produce different brain waves or rhythms of electrical voltage, depending on their mental state. 

Deep sleep has a different rhythm than dreaming and full alertness has a different rhythm than relaxation.  Our brainwaves serve a purpose to help us cope with various situations. This could be to calm us down after a long day or to pump us up for something new and exciting.  Our brainwaves serve a purpose to help us cope with various situations, whether it’s to calm yourself down after a long day or pump ourselves up for something new and exciting. 


Each brainwave has a distinct purpose and helps us behave, think, move and process.  The five brainwaves (in order of lowest frequency to higher) are:   Delta, Theta, Alpha, Beta and Gamma.  


Delta (0.5-4Hz).  
Often called the deep sleep wave, it is the slowest of the frequencies and is experienced in deep, dreamless sleep and in very deep transcendental meditation and hypnosis states, or the realm of your unconscious mind. Deep sleep is vital for deep healing and regeneration.

Theta (4-7.5Hz).
Theta waves are present during hypnosis, deep meditation and light sleep, including the REM dream state.    It is the alpha-theta change from 7Hz to 8Hz, which is the optimal range for visualisation, mind programming and where the creative power of your mind begins.

This is the mental state in which you consciously create your reality. You are conscious of your surroundings however, your body is in deep relaxation. This level is the one most commonly found when we have hypnosis or self-hypnosis.

Alpha Waves (7.5-14 Hz).
Alpha waves are present in deep physical and mental relaxation, and usually when the eyes are closed, daydreaming, or in light meditation. It is the optimal time to program the mind for success and it also heightens your imagination, visualisation memory, learning and concentration.    When we take our brain rhythm to alpha, we put ourselves in the ideal condition to learn new information, perform complex tasks, learn languages and analyse complicated situations.    Meditation, guided visualisation and relaxation activities that enable the sense of calm, also enable this alpha state. Considered as an integral part of the relaxation process before sleep. The alpha frequency band has been studied extensively in meditations and in almost all cases an increase in the alpha waves has been shown during meditative states.

Beta (14-40Hz).
Mostly we operate at the beta brain rhythm, which is our normal waking consciousness, where we have a heightened state of alertness, logic and critical reasoning, but this can also translate into stress, anxiety, fear and restlessness.

Gamma waves (above 40Hz).
Considered the 'insight wave', this is the fastest frequency at above 40Hz.

Research shows Gamma brain waves are associated with bursts of insight and high–level information processing.    Increasing the amount of gamma waves in the brain can help you to process information better, increase and sharpen focus, and aid and improve long and short term memory.  In addition, increasing gamma brainwaves can also help you experience more peace of mind, better sleep, less anxiety, and a lower risk of depression.

The significance of understanding our brain waves is that through relaxed meditative practice, we can reduce our anxious brain wave states and move into calmer states.   It shows us the importance of being in meditative, relaxed states, which can be achieved with hypnosis and guided visualisation.
