Theta waves that occur within our brain during sensory deprivation tank sessions is akin to the feeling just when we drift off to sleep or the moment we start to stir when we are awaking in the morning. At these times we are not entirely consciously thinking, this is the theta state.
For the most party what we remember from these fleeting moments include vivid imagery which are also known as hypnagogic images. Apart from that, during these moments we also go into an open ‘thought plain’ where we ponder about things me normally do not ponder about.
Thus, it can be said that in these states our unconscious thoughts and our conscious experiences cross paths which is among the reason as to why we tend to remember them. Based on scientific observations theta states are the same states that Hindu and Buddhist monks achieve during meditation (Zen meditation), however, only those with years and years of experience are able to reach these states after a significant period of time.
The good news is that via sensory deprivation tank usage, individuals are able to achieve these same states within minutes of being in a float pod filled with Epsom Salt. Sensory deprivation tanks are able to access the elusive theta state within minutes. To make a long story short, individuals are able to move into Theta states using a sensory deprivation tank what takes a meditation practitioner 20 years to achieve. Now you are probably asking why is this state so important and what is good about it.
Well, for starters the theta state has been observed to be linked to nurturing emotions or feelings of well-being, enhanced relationships construction, creativity, social adeptness and most importantly a reduction in stress levels. This state also stifles negative emotions from occurring which include anger and anxiety which in general lead to a host of other issues.
Put all this together and what we have is a mechanism that will decrease the chances of stress-related illnesses which include cardiac disease, mental problems, stroke, and depression. To move into the subject just a little deeper, these biological activities occur in the theta state because in this state of being, the production of positive neurotransmitters is enhanced significantly. By positive neurotransmitters, we mean ‘feel-good chemicals that our bodies produce naturally and some of these are endorphins and dopamine.
This is not all as; in this state another thing that happens is the reduction in production of stress-related neurotransmitters such as cortisol and adrenaline. Science has provided strong enough evidence that associates theta waves and learning abilities or metacognition abilities and this could be the primary reason behind the fact that those who frequently attend sensory deprivation tank sessions have a much higher level of focus, creativity and problem-solving skills apart from the fact that they are generally healthier too.
To simplify matters, let us just say that sensory deprivation tanks work and this is why medical practitioners seem to recommend it more and more as a supportive treatment for a variety of ailments that range from chronic pain, arthritis and depression to difficult pregnancies, PMS discomfort and back aches!
