Entrainment is the process by which two interacting oscillating bodies, with different periods when, functioning separately, assume the same period. These two oscillators often fall into synchrony; though, other phase relations are possible.
When a tuning fork, tuned to a G note, is placed close to a guitar and struck, the guitar's G note will be sent into vibration. This phenomenon has been studied for years in relation to the functioning of the brain. The human brain is usually throbbing with electrical impulses. The brain's electrical activity is often measured through an electroencephalogram (EEG). The machine actually records the frequency of the brainwaves (the electrical impulses) in Hertz (HZ)
The main frequency with which your brain is reverberating at any given moment is usually connected to your state of mind. Therefore, your state of mind, whether relaxed, sleepy or frightened, can be detected in your brainwave frequencies.
These frequencies have been organized into 4 broad groups together with their associated state of minds.
Delta Waves (3-5Hz): The waves are linked with deep sleep, unconsciousness and especially deep meditation. Staying conscious through delta requires practice.
Theta Waves (4-7Hz): These waves arise during sharp states of creativity. They are often associated with deep meditation. Seek theta and you will get access to unconscious material, or reveal creative ideas and insights.
Alpha Waves (8-12Hz): These waves are linked to some light meditation associated with daydreaming.
Beta Waves (13-20Hz). These waves are connected to normal awaken consciousness and are predominant when you are focusing on the outside world's activities.
In the past, you could achieve brainwave entrainment through hours of quieting your mind and enticing your brain to these different states. However, in present world these benefits can be easily realized through use of special audio programs designed for this particular purpose.
Depending on the type of frequency used in the sound wave, the four states of mind are achievable with the following beneficial effects:
1. Aid meditation
The major significant outcome of meditation is a change in your brain frequency from a high state to lower one like delta, alpha, or theta. While 'meditators' spent years learning meditation techniques; you can nowadays achieve the same feeling using this brainwave entrainment. This can be achieved easy, quick and with no great discipline or special training. Meditation frequencies are normally experiential in the alpha range (8-13Hz).
2. Shorter learning time
The theta state (4 - 7Hz) has been recognized to boost learning potential. As a matter of fact, children have more time in theta stage compared to adults, which perhaps explains the speedy learning potential of children.
Alphas are also helpful when learning. You may play subliminal tapes, language cassettes, etc. through an entrainment for an utmost effect.
3. Reducing sleepiness
Half an hour each day in the Theta state may restore up to four hours of your valuable sleep.
4. Certain mental illness treatment
Brainwave entrainment can be applied in treatment of attention-deficit disorder, depression, alcohol and drug addiction, autism, low self-esteem. Brainwave entrainment also helps ease migraines and headaches.
5. Stress reduction, improved health and relaxation
Stress usually cause some chemical changes in your brain which end up affecting your health. By changing the state of your brain through brainwave entrainment, you can greatly improve your health. By bringing your brain frequency down to an alpha state, your stress will melt away. While diet and exercise helps relieve stress, brainwave entrainment adjusts your brain program to exercise and also improve your diet.
Other Reported benefits of brainwave entrainment, by users, include:
1. Increased sex drive.
2. Deeper spiritual connections
3. Helps get rid of bad habits (behavioral change).
The benefits of brainwave entrainment are just outstanding.
