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.
As 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.
Taking a break from gravity in a 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.
A 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.
