Brainwaves To Help you Sleep
Have you heard of brainwave entrainment for sleep? It is an innovative way to go to sleep. (It can do more than induce sleep but for now let's stick to sleep induction.) This article explains what it is all about.
Your brain uses electrical signals to communicate with all the systems in your body. The electrical pulses vary in the their rhythm depending on what you are doing. When you are wide awake your brain waves pulse faster than when you are relaxed.
The rate of these electrical pulses can be measured using an EEG (electroencephalograph) machine. They are called brainwaves because that is how they appear.
When we are alert and busy the activity in our brains is faster and the waves are closer together. When we are relaxed the wave pattern is much slower and when we first drop off to sleep it is slower still.
If, when you go to bed you are tense and anxious, or perhaps trying to solve the problems of the day, your brain waves will be running quite fast. The waves captured on an EEG will show waves that are close together and spiky. They are known as beta waves.
Relaxation causes your brain waves to pulse more slowly and the waves associated with relaxation are usually alpha waves.
You need to be relaxed for sleep to come, and yet relaxation can be very hard to achieve at times.
Brainwave entrainment for insomnia uses sound to change the rhythm of your brain waves to the rhythm of sleep.
The idea is to get the brain waves to slow right down to alpha and then slower still to theta and then delta waves. Gradually the brain's rhythm synchronizes with the beat or tone that you are listening to. As your brainwaves slow down your body and mind relax and you drift down into a natural sleep. This can be seen in this image showing the brain matching the rhythm it hears which in this case is a 10hz pulse.

This process is backed by a mountain of scientific research conducted over the past 70 years. Much has been discovered since the initial work in the 1930s and work continues today. Let me quote from just one of the scientists working in the field:
"Its difficult to try to responsibly convey some sense of excitement about what is going on…the field is wild and intriguing… We are at a frontier, and its a terribly exciting time to be in this line of work" John Kiebeskind, UCLA neurophysiologist.
The Sleep Sound CD uses this technology to slow your brain waves into relaxation and then to sleep. As your brain waves are slowed into a normal sleep rhythm your body begins to follow suit and you drift off to sleep easily and naturally. All without having to knock yourself out with pills.
