Float therapy, also known as sensory deprivation therapy, is a unique alternative therapy that involves immersing oneself in a sensory deprivation tank filled with saltwater. A person floats in the tank for a specified amount of time, typically around an hour. The environment is kept quiet and dark. The buoyancy of the saltwater allows for weightlessness. It also reduces pressure on the joints and muscles, while sensory deprivation can aid in relaxation and reduce stress levels. Facilities with float tanks can be found with simple searches, and many health and wellness spas hold their float tanks.
