It's a place to effectively train your nervous system to be more relaxed through the practice of flotation therapy.
It's a place to effectively train your nervous system to be more relaxed, and less affected by life's bullshit.
This is achieved through the practice of floating. In this practice you enter what is essentially the world's most high tech enclosed bathtub, which contains 11" of water blended with 1000lbs of epsom salt. You get naked, lie down in the solution, and effortlessly float. The water is heated to the same temperature as the surface of your skin which makes it skin receptor neutral (if you lie still you will stop feeling it). There is no light, no sound, no external sensory stimulus whatsoever, and even the effects of gravity are almost entirely remediated.
