Floatation therapy simulates zero gravity by dissolving 800-1000 lbs of Epsom salt (magnesium sulfate) into approximately 200 gallons of water in a small shallow pool.
There are several important benefits to creating this dense saltwater solution. The most immediately recognizable benefit is that a person floating in a floatation tank will float like a cork in only 10 inches of water, with their face and the top of their body actually poking out of the water. This is regardless of the person's body type or their ability to float in a swimming pool.
Anti-GravityAs opposed to a swimming pool where gravity is lowered, gravity in a floatation tank is essentially nullified by the extreme buoyancy caused by the dissolved Epsom salt. This provides a rare opportunity for people who are suffering from various types of joint and/or muscle pain. Without the constant pressure of gravity, a person resting in a floatation tank is able to relax and unwind more thoroughly than even the most comfortable bed allows.
Floating Releases EndorphinsTaking a break from gravity in floatation tanks also causes fascinating and significant changes in the brain. Endorphins are released. These are powerful natural pain relievers and mood enhancers that promote a sense of well-being while further enhancing the healing benefits of the zero gravity environment.
Meditative State of RelaxationA person who has a high stress level will find it virtually impossible to maintain that stress level after a float session due to endorphins being released in the brain as well as their brainwaves shifting from beta to alpha and even theta. Theta is a rare brain state that is normally reserved for people trained in meditation. An important contrast to meditation is the fact that a person can achieve a theta brain state in their very first float session, making it a quick and easy shortcut to deep relaxation.
The benefits achieved in a one hour session are significant on their own, but when compared to other therapies, floatation tanks are in a category all their own.
