Joe Rogan speaks on sensory deprivation tanks and the awesome potential you can achieve with one.
"In newer tanks, epsom salt is added to the water in the tank to increase the density of the water so that the subject floats with the face above the water. However, since the ears are submerged when the subject is in a relaxed position, hearing is greatly reduced, particularly when ear-plugs are also used. When the arms float to the side, skin sensation is greatly reduced because the air and water are the same temperature as the skin, and the feeling of a body boundary fades. The sense of smell is also greatly reduced, especially if the water has not been treated with chlorine.”
"A therapeutic session in a flotation tank typically lasts an hour. For the first forty minutes, it is reportedly possible to experience itching in various parts of the body (a phenomenon also reported to be common during the early stages of meditation). The last twenty minutes often end with a transition from beta or alpha brainwaves to theta, which typically occurs briefly before sleep and again at waking. In a float tank, the theta state can last for several minutes without the subject losing consciousness. Many use the extended theta state as a tool for enhanced creativity and problem solving or for super learning. The more often the tank is used the longer the theta period becomes.”
"Floating can be passive or active, depending on the purpose. For relaxation, one simply floats and ‘clears the mind.’ Active floating has many different techniques. One may perform meditation, mantras, self-hypnosis, utilize educational programs, etc. The idea of active floating is that, when the body is relaxed, the mind becomes highly suggestible and any action taken during these states will enter the information into the sub-conscious. Flotation therapy may be used to complement other body work and healing methods.”
"Perceived stress can be correlated with increased levels of cortisol and in flotation therapy there is a natural tendency for cortisol to be reduced. For this reason, floatation therapy is one of the few noninvasive techniques available to manage stress when it is a factor in reducing a person’s ability to cope with normal life. Flotation therapy is a fast technique in this respect. The Swedish research was based on 40 minute float sessions. This compares well with other management techniques such as long vacations.
There are many similarities with the age old long hot bath, the differences being that in floatation therapy the temperature is maintained at the correct level and the bath is large enough to float without touching the sides of the bath.”

*I’m going to use one of these up in Boise. The place is called Good Floatations, and I’m very excited to try this thing out.
