Those seeking help with sleeping problems can find a safe and healthy answer to their prayers with certain types of audio therapy.
Not all kinds are effective, such as hypnotic or subliminal suggestion messages embedded in a soundtrack.
These just prove very ineffective.
However, there are other types of listening therapies which train the brain to fall into a sleep.
The science behind how this works is simple.
To illustrate, think of how a long drive down a lonely stretch of road can affect the motorist.
As his heartbeat attunes itself to the "beat" of the passing segments of broken white line in the road as he passes over them, this can cause him to become dangerously drowsy.
It's relatively the same cause and effect at work here.
To use this in a positive manner, it can greatly help with sleeping problems.
Binaural pulse therapy was one such popular variety of this type of method.
Two nearly similar sets of tones and pulses, being just slightly out of frequency phase with each other, are each sent to each ear.
The proper brainwaves are set in motion as the brain processes these as a single signal.
The only drawback with this was the need to wear stereo headphones while sleeping, and keeping them from getting knocked of the ears during sleep.
It just didn't work out very well.
Isochronic pulse therapy is the latest, most effective type of treatment in this field, as it causes the same effect, but requires no stereophonic equipment to implement it.
A simple, regular CD player is all that's necessary, and those looking for help with sleeping problems find sleep in mere minutes.
