A float tank is a small shallow pool filled with water nearly saturated with Epsom salt, so individuals float effortlessly. The tank is kept warm, at body temperature, and it is enclosed so it is completely dark and quiet. It’s utterly relaxing.

Excessive stress exacerbates many chronic health conditions. Floating is a natural and chemical-free way to bring down the amount of stress in one’s life. Nothing gives the brain and body a more complete rest than a float tank. It automatically triggers a physiological relaxation response, the opposite of fight-or-flight, and tells the body it can let down its defenses and clean up the excess adrenaline and cortisol.
