What is Brain Entrainment?

To understand brain entrainment it makes sense to first explain what brainwaves are. Put simply, brainwaves are patterns of electrical activity in the brain.  Our brain is like a electrical organ made up of billions of cells called neurons. Neurons fire electrical signals. As a result, the brain creates new neural pathways to connect both hemispheres of the brain. These electrical signals of the brain can be shown on EEG (electroencephalograph) monitors. They look like wave forms.

Brain Entrainment is a vital link in reducing insomnia


When the brain is more active there is more electrical activity present and vice versa. Knowledge about brainwave activity has been improved since the invention of EEG (electroencephalograph) machines which can measure it accurately. From this research we know the level of brainwave activity which is associated with deep sleep and those that are associated with lighter sleep, full consciousness and so on.

These wave forms are called brainwaves and are grouped into Beta, Alpha, Theta and Delta waves

Electrical brain activity is measured in Hertz (Hz).

Beta  13 -25 Hz (Normal state of alertness, stress, anxiety)

Alpha 8 – 12 Hz (Light relaxation ,

Theta 4 – 7 Hz (Deep relaxation , meditation, focus)

Delta 1 – 3 Hz ( Deep sleep, rejuvenate immune system)

Good sleepers naturally go down through the levels easily. People who have trouble with insomnia and sleepless often have trouble reaching Theta levels let alone Delta levels. Brainwave entrainment can help slow down or help speed up brainwaves. When brainwave entrainment gets down to around (1-3 Hz) , otherwise known as Delta stage this induces deep sleep. There are different types of brain entrainment techniques. Sleepora uses the latest bespoke binaural beats and isochronic tones as part of its program. Brainwave entrainment is very safe. In fact NASA and Fortune 100 companies are constantly using Brain Entrainment therapies in areas such as enhancing memory, focus, meditation and relaxation

A common benefit to increasing the amount of slow brainwaves (ie. Alpha, Theta, Delta) in your brain is feeling deeply relaxed. Scientists have found that when the brain is in slower brainwave states it produces specific hormones and “neuropeptides”. These hormones and neuropeptides that are produced have been linked to boosted memory, creativity and ability to learn.

How does brain entrainment work?

Brainwave entrainment is otherwise known as “brainwave synchronization”. This terminology covers a number of methods which are used to guide brainwave frequencies into matching up with (or getting into rhythm with) certain frequency stimulus’. These stimuli encourage particular brain states (eg. to induce sleep).  This practice is based on extensive research showing differing frequency levels in our brainwaves as we enter different states throughout our daily lives. Audio (aural) expertise and tools are generally considered the best way to produce the appropriate frequencies to encourage these changes in mind state.

One way to think of it is to is to think of how your state changes when you listen to a relaxing piece of music. Now magnify this several fold and you start to get an idea of how brain wave entrainment works.

Different types of brain entrainment such as binaural beats and isochronic tones work in differently ways. However the effect of each is very strong

 Brain entrainment is a vital link in reducing insomnia levels

Brain entrainment has been used to help cure insomnia for a number of years. However new developments, knowledge and advances in techniques have now made it even more effective.

The Sleepora Program uses safe brainwaves entrainment with binaural beats, isochronic beats, whitenoise, and specific audio enhancement techniques to naturally help people improve the quality of their sleep as well as reduce stress and anxiety.
