Float therapy, also known as floatation therapy, is a sensory deprivation practice that involves floating in a tank filled with Epsom salt water heated to skin temperature. The high salt concentration of the tank makes it easy for the user to float on their back with the back of their head partially underwater. The tank is soundproof and dark, which provides a sensory deprivation experience that encourages the user to go into a quiet, meditative state while floating. The user is completely buoyant in the Epsom salt water, which creates a feeling of zero gravity with no real concept of up, down, time, or space. The main benefit of using a sensory deprivation tank is to ease mental anxiety and muscle tension. The near-weightless environment of floating allows for the muscles and joints of the body to relax, increasing blood flow and helping to more quickly repair muscle tissues and heal the body. Floatation therapy is designed to help the mind, body, and spirit to relax, recover, and reset. The therapy is used by athletes, biohackers, and even those battling mental illness, and everyone is recognizing the life-changing power of frequent floating.
