... Once you close the hatch it’s pitch black inside and nearly soundproof. The salt water in the tank is kept at skin temperature. The result of this sensory deprivation is you forget you even have a body and you experience wave after wave of complete and total relaxation. After meditating for more than twenty years I would say an hour in the tank, once you're experienced, equals a solid five hours of meditation. Pure bliss. Forget about a Lambo, I'm buying one of these float tanks when crypto moons again. : )
