Meditation and Brainwaves
Control your brainwaves and you control your state of mind. By raising or slowing our brainwaves, we can altar how we think, feel and act. Meditation is the process of slowing our waking beta brainwaves to the slower states of alpha and theta. By learning to control these states, we can improve our health and well-being.
Brainwaves are the electrical movements in the brain. The frequency of these brainwaves can be measured using an electroencephalograph (EEG). Electrodes placed on the scalp measure the frequency of these brainwaves. From highest to lowest frequency, these brainwaves are called beta, alpha, theta and delta.
Beta is the waking, thinking state. During beta, brainwaves range from 14 to 40 cycles per second. In beta, an individual thinks and listens, can solve analytical problems, make decisions, and intake and process information. This is our normal state of mind when working, going to school and shopping. During beta our minds are the most alert.
Alpha is a slower state more indicative of relaxing and reflecting. During alpha, brainwaves range from 9 to 14 cycles per second. In the alpha state, an individual is fully aware of his/her surroundings but in a much more relaxed state of mind than beta. Meditation is often practiced in the alpha state.
Theta is an even slower state perfect for daydreaming and intuitive thinking. During theta, brainwaves range from 5 to 8 cycles per second. It is the state between wakefulness and sleep. In this state of mind, memories, thoughts and facts that eluded a person in a wakeful state can be recalled. It is often in this state that answers to problems seem to appear. Deep meditation and prayer are practiced in the theta state.
Delta is the slowest of the four states where sleep occurs. During delta, brainwaves range from 1.5 to 4 cycles per second. At the slowest delta level, sleep is deep and dreamless.
During our waking and sleeping hours, the brain moves through all four of these stages. At any given level, there is a range in brainwaves that effect how deeply we have entered that state. By knowing how these states function, we can knowingly enter a particular state and control how our thoughts are processed.
Jose Silva wrote in his book The Silva Mind Control Method, “When you are wide awake, doing and achieving in the workaday world, you are in Beta or ‘outer consciousness’. When you are daydreaming, or just going to sleep but not quite there yet, or just awakening but not yet awake, you are in Alpha. When you are asleep you are in Alpha, Theta, or Delta, not just Delta alone, as many believe. With Mind Control training you can enter the Alpha level at will and still remain fully alert”.
Meditation allows our minds to move through these states leading us to a healthy lifestyle. When we control our brainwaves, we control how we think, feel, reason and react. Relaxation, creativity and self-awareness flow naturally. As we mediate, our physical health improves as we move closer and closer to a healthy lifestyle. Consciously controlling our brainwaves is a step towards healthy living.
10 Fun Facts About Breathing & the Respiratory System
Our ability to breathe is fascinating, as it’s one of the only systems in our body that can be controlled both voluntarily, through the central nervous system, and more often involuntarily, through the autonomic nervous system. This overlap between the two systems is the reason why focused, intentional breathing methods through yoga and meditation are able to affect other involuntary muscles like the heart.
Our breath is what gives us life and without it, the human body cannot exist. But is it possible to better your life by paying more attention to how you breathe?
While breathing is so commonplace to our existence, proper breathing techniques and awareness of breath can have dramatic implications on our health. Having knowledge of specific breathing techniques can lower stress, help you sleep, help your mind function more acutely, and even curb food cravings.
When we breathe, the average adult draws in about 13 pints of air into the lungs every minute. From the lungs, that oxygen is then transferred from the air sacs in our lungs throughout the body via red blood cells to the blood vessels that distribute it to nearly every system. Meanwhile, waste gases, like CO2, are exchanged and filtered out.
For the average person with good lung health, the amount of oxygen in the blood, or the arterial blood gas (ABG) oxygen level, should be somewhere between 95-100 percent oxygen.
