Sleep problem remedies of many varieties and techniques have been researched into and experimented with which have provided many interesting results.
The main reason for the need for alternative remedies is of course the addictive factor of chemical based medications, or sleeping pills, which have proven more of a hindrance than any help.
Sleep problem sufferers can now be able to use alternative remedies which are non-intrusive, non-addictive, and completely safe.
However, some of these alternative methods are more successful than others.
The use of playing music which has had subliminal messages embedded in the sound tracks has been looked into, but showed almost no results.
While subliminal messaging embedded in department store music may prove helpful with deterring shoplifters, using this for combating a sleep problem just isn't the best of remedies...
it's a whole other part of the brain to deal with.
Hypnosis has also been done, and it shows some somewhat satisfactory results, but each session can be phenomenally expensive, with series of sessions lasting many weeks or months - even years.
The most advanced remedy to date would be the use of isochronic pulse audio therapy.
It's a bit like listening to relaxing music, but with a little added feature.
In the background of the soothing and relaxing musical tones, is a barely audible track of pulses at certain frequencies, and these frequencies are rapidly ever-changing, which induces certain brainwave patterns and behaviors in the brain.
After a number of these non-addictive sessions, the brain has been trained back into normal, natural sleep patterns, and you won't need the therapy any more.
Of all sleep problem remedies, this one seems the best.
