Ionic foot baths work by sending an electrical current through a tub of water, which causes the water molecules to divide and create negative oxygen ions. Once enough are present in the water, the body absorbs them through osmosis, which is the movement of compounds from higher to lower concentration.

The process is quick and simple - you soak both feet in a basin filled with warm Himalayan saltwater. An ionic array is placed in the basin, which sends an ionic current into the water. The combination of the water, salt, and ionic array are meant to generate negative ions by separating oxygen and hydrogen from the water, neutralizing charged particles in the body and drawing toxins with the opposite charges out.
