Brainwave entrainment is a method to stimulate the brain into entering a specific state by using a pulsing sound, light, or electromagnetic field. The pulses elicit the brain’s ‘frequency following’ response, encouraging the brainwaves to align to the frequency of a given beat.

So what is a brain wave? In brief your brain is made up of billions of brain cells called neurons sending signals whenever you do something and this generates electrical activity which medical equipment such as EEG’s measure. So you may have seen brain wave patterns looking like a squiggly line. There are five different brain wave patterns and the optimum brain frequency is the Gamma brain wave which creates all those ‘feel good’ feelings for yourself and others. Everyone has some Gamma activity but it is the highly productive, the natural optimists or those focused on peak performance like athletes who know how to get in ‘the zone’. And for the rest of us pessimists… hooray there is a cure, we just need to know how to increase our Gamma wave activity. But more about that later.
Most of us that who have stressful lives walk around with Beta brain wave rhythms which are the most jagged. We create Beta brain waves when we think logically, over analyse situations and feel tense or afraid and it’s these brain patterns that create many stress related issues such as headaches and depression.
So when you decide to relax a little and make time for some yoga or listen to some music, it’s not just your body that gets a breather… your brain waves will also be slightly less jagged as you move into the alpha state. That’s when your start to reduce your blood pressure and feel less anxious.
When you feel highly creative or inspired then the Theta brain waves will kick in. They activate in the early stages of sleep but also in a state of day dreaming.
But now for the exciting bit. If you meditate or use guided visualisations where you begin to sink down into a deep relaxed state within yourself… then your brain activity slows down even more into the Delta brain wave pattern… which is also connected with sleep. When Delta Brain Waves increase, so does your natural ability to: release natural growth hormone as well as anti-aging hormones as they reduce the level of a hormone released under stress called Cortisol. You heal your mind and repair your muscles and boost your immune system as you would in deep sleep and connect more with your intuition.
As you regularly stay in this deeply relaxed station of meditation or deeply relaxed visualisation such as self hypnosis where you count down, then you then begin to enhance your Gamma brain wave activity. Gamma brain waves are the fastest documented brain wave frequency range and a powerful natural antidepressant making you feel happy for no reason and that feeling of joie de vivre as it also helps you to feel increased empathy and compassion for others. And this effect on your mind and body can last for days! There is no doubt about it the Gamma brain frequency is the key to better emotional, physical, psychological and spiritual health as it balances the right and left hemispheres of the brain.
What increased Gamma brain wave activity does for you: You will have more emotional self control so you able to stick to a weight loss plan or control your anger; your memory will be sharper as will your sensory experiences so food tastes better, smells are more powerful and hearing is amplified. It enables you to process large amounts of information in short amounts of time so learning new subjects is far easier. And it continues to increase those anti aging hormones, helping you to look and feel younger. And not only that it also enhances your creativity and intuition. How’s that for an entire brainwave goody bag of happiness.
So before you decide to have several glasses of wine after work with a take away as you slump in front of the tv just remember that whilst that’s fine… also remember that the deep breathing Hatha yoga class, visualisation CD or meditation before you go to sleep for only a couple of times a week may just give the golden ticket to living an enhanced healthy life of fulfillment and happiness. And it’s all completely free!
Brainwave entrainment is a method to stimulate the brain into entering a specific state by using a pulsing sound, light, or electromagnetic field. The pulses elicit the brain’s ‘frequency following’ response, encouraging the brainwaves to align to the frequency of a given beat.
This ‘frequency following’ response of brainwave entrainment can be seen in action with those prone to epilepsy. If a strobe flashes at their seizure frequency, the brain will ‘entrain’ to the flashing light, resulting in a seizure.
On the positive side, this same mechanism is commonly used to induce many brainwave states; such as a trance, enhanced focus, relaxation, meditation or sleep induction. The brainwave entrainment effectively pushes the entire brain into a certain state.
Brainwave entrainment works for almost everyone. It is a great way to lead your mind into states that you might usually have difficulty reaching, allowing you to experience what those states feel like.
THE HYPE
There is a lot of marketing hype around brainwave entrainment. It is sold with promises of increasing IQ, promoting weight loss, ‘mind-tripping’, enhancing creativity, concentration, inducing spiritual states and more.
While these claims are not entirely true, they are not altogether false either. In practice, the claims are based on an overly-simplistic view of how the brain and the brainwaves function.
THE RUB
People are very seldom deficient in a certain brainwave type in all areas of their brain. Usually the distribution is much spottier, with an excess in one area and a deficiency in another.
We are all different, especially when it comes to the distribution of our brainwaves. Boosting a certain brainwave state may be beneficial for one person, and emotionally uncomfortable for another. Without knowing each person’s starting position, entrainment can be rather ‘hit and miss’.
If brainwave entrainment leaves you with unwanted side-effects (see below) or discomfort, you’re probably encouraging a range of brainwaves that are already excessive in some area of your brain. The way around this is to get a brain map to see what your brain’s strengths and weaknesses are, and see what (if any) brainwaves could use some encouragement.
