There are many parts of our body that go through regular cycles. The National Institute of General Medical Sciences state that “Circadian rhythms are physical, mental and behavioral changes that follow a roughly 24-hour cycle, responding primarily to light and darkness in an organism’s environment. They are found in most living things, including animals, plants and many tiny microbes. The study of circadian rhythms is called chronobiology (para 1). It is related to our biological clock. Further, circadian rhythms can influence sleep-wake cycles, hormone release, body temperature and other important bodily functions. They have been linked to various sleep disorders, such as insomnia. Abnormal circadian rhythms have also been associated with obesity, diabetes, depression, bipolar disorder and seasonal affective disorder (para 7). Females often are aware of their position on their monthly cycle which ultimate determines and controls fertility. Other cycles include the elimination of what you have ingested, eating and digestion, and absorption and use.
The average person is usually shocked to find that the brain actually also goes through cycles. How do these waves happen? They occur naturally in our brains from the firing of neurons – there are electrical cells in our brain who communicate with each other and can be measured with an electroencephalogram, better known as an EEG. From studies in the 1930’s and 40s, scientists discovered these cycles and found the higher the cycle, the higher the awareness. Subsequent studies found sensory motor rhythm (SMR, 14 Hz) which links brain and body functions and gamma brain waves (39-100 Hz) are found in highly trained mind such as highly experienced meditators and highly focused work and the integration of data in the mind.
Many believe that these cycles can be manipulated and used to assist one to train their brain (or maybe be trained by their brain). On those days, that you feel focused, alert and ready to work, your brain is in beta. Beta waves range from 40-13 Hertz. Hertz is a scale of measurement, The hertz (symbol Hz) is the unit of frequency in the International System of Units (SI) and is defined as one cycle per second (cps). Heinrich Rudolf Hertz first established conclusive evidence of the existence of electromagnetic waves.
When you are in a creative, laid-back, relaxed state, you have lowered your cycles per second to the Alpha state. That sharp state has slowly transitioned to a calmer brain wave. Many find this helpful for creativity, creative visualization, prayer and light meditation, grounding and centering one’s self, stress and anxiety reduction. Alpha is also the gateway to other states of consciousness. At this Hz of 12-7, some way it is an optimum way to reduce blood pressure and increase health. You are right below consciousness, or have descended to below the level of normal awareness. According to Tools for Wellness, “alpha is also the home of the window frequency known as the Schuman Resonance – the resonant frequency of the earth’s electromagnetic field. From this scientific, measurable state, many say this is where the metaphysics begin. Is this the window that those who claim to have the gifts of prophecy, psychic work or mediumship as well as the place where behavior change can work more easily?
Theta is the next level, 7-4 Hz, it is lower and some claim it to be the place where the brain is working much slower. Some psychic healers say this is where the deepest spiritualist work can come. Some say this is a where your brain is said to be when you are in surgery or even in a coma. You are so close to sleep, but yet still retain a tiny amount of awareness. This is the area where one can work on intuition, memory, and deep meditation. This is where the brain can help one in overcoming addictions, quicker learning and retention, dream recall and deep hypnosis.
The final state is Delta,4-0 Hz, the slowest brain waves possible before death, but similar to a deep, deep sleep It has been said this is where one can experience an increase of the human growth hormone. Delta is an area that is best used only for sleep and with the assistance of professionals.
Fascinating, isn’t it? Imagine the applications! This is science that meets the medical community, the psychological fields and adds an interesting twinge to the fringe science known as parapsychology.
