WHAT IS A FLOAT TANK?
A float tank also goes by the name of a sensory deprivation tank or isolation chamber. In short, a float tank is an environment created in which you experience zero light, zero sound and zero gravity. The tank has approximately 10 inches of water inside and is filled with 500kg of magnesium sulphate (Epsom salts). This allows you to float effortlessly with no external input to consider as the salt keeps you extremely buoyant and with the lack of sensory input promotes one hemisphere of your brain to relax and slow down, in turn, enhancing the creative hemisphere of your brain to reach a THETA state. Approximately 80% of the general population have a magnesium deficiency, by floating in the magnesium sulfate, your body slowly absorbs what you need from the magnesium, replenishing your system.
Floating has a huge range of benefits. First and foremost is relaxation. The aim is to guide the mind from the BETA state (waking rhythm 13-30Hz), through ALPHA state (unfocused rhythm 8-12Hz), until you achieve the THETA state (Dreamlike rhythm 4-7Hz).
Floating is not a new age concept. It was developed by a medical doctor names John. C. Lilly almost 60 years ago and has undergone rigorous medical studies that have been reviewed and published in numerous medical journals.
People seem to be surprised in discovering the amount of actual scientific research that has been done on floating in flotation tanks. The benefits listed are taken from over 200 research articles containing both lab experiments and case studies published between the 1960′s and today.
