It is next to impossible to drown in a sensory deprivation tank.
No, drowning in a floatation tank is one of the most common myths of sensory deprivation. It is next to impossible to drown in a sensory deprivation tank. It is impossible to not float in a sensory deprivation tank because the Epsom salt causes changes to the composition of tank water making drowning in a floatation tank incredibly difficult. The water in a floatation tank is about 12 inches deep and contains hundreds of pounds of Epsom salts that increase the density and buoyancy of the water, allowing the individual to float with ease. The fluid temperature is maintained at external body temperature (around 95° Fahrenheit) by a coil. The water is sterilized with a peroxide solution and UV filtration. Inside the chamber, the participant floats effortlessly without gravitational requirements and with reduced stimulation of sound and light. While it may seem scary to enter the tank and relax for an hour, there is nothing to fear. Thousands of people use this tank successfully every year and the numbers are gradually growing. However, people with infectious diseases, pregnancy, and those who are epileptic (not on controlling medication for the condition) should avoid using the tank.
