Ever since the concept of the sensory deprivation tank or floatation therapy was introduced to the health sector its benefits have been observed to be phenomenal.
The reason as to why this therapy has taken more than half a century to get to where it is currently within the main stream health sector can be attributed to the lack of scientific instruments and knowledge of the sensory deprivation tank at the time it was invented by Dr. John Lilly in the mid 1960's.
The scientific community were not only sceptical about the entire concept of floatation therapy which was way ahead of its time, but they did not have sufficient knowledge about the human biological structure pertaining to the ability of the human mind to repair, reconstruct and re-stabilise itself on its own accord if given the opportunity.
However, at the advent of the 80s when brain function theories were pursued aggressively by the scientific community and empirical observation based on clinical trials of athletes using floatation therapy to enhance their athletic performances were beginning to show positive results.
Researcher began to realise a strong correlation between enhanced brain functionality and those who subjected themselves to floatation therapy at least once or twice a week. On examining the correlations, researchers found that a variety of biological issues that were 'of synch' within were rectified when the brain was a given a reprieve from the bombardment of external stimuli which included sound, vision, smell, heat and most of all the constant engagement between the brain and the effects of gravity.
This is based on the fact that whilst an individual is in a sensory deprivation tank, he or she is removed from the 'normal environment' where they have to contend with issues such as gravitational forces where the brain has to constantly balance the entire anatomy towards the effects of gravity.
How this is possible is due to the weightlessness that 'floaters' experience when they are in a floatation tank as the high content of Epsom salt in the solution that they float in does not allow individuals to sink and added to the fact that the solution is heated to skin temperature makes it impossible for those floating to tell the difference between the parts of their body that is submerged and the parts that are above water.
This situation coupled with the fact that the floatation pods that they float in are also commonly light, smell and sound proofed, allows the brain to detach itself from its normal preoccupation with these external stimuli and instead redirect the resources that have been 'freed' to focus on internal biological functions where the brain is able to reorganise and condition nutrient allocation, blood circulation, neurological functions and other critical biological activity within that can only be accessed by the brain.
To put floatation therapy into a more comprehensive perspective, floatation is similar to the conditions that an unborn child experiences while it is in a mother's womb.
This condition is necessary for the baby during its formative stages which allows cells to do what needs to be done without having to contend with external forces/ stimuli that may disrupt, influence or redirect cell behaviour.
