What is Basalt?
Basalt has been chosen for its unique ability to emit far-infrared rays at room temperature, as well as negative ions. Far-infrared rays, known as Growth Rays, slowly permeate your body, speeding up the release of toxins through perspiration. Basalt’s high negative ion emission replicates natural environments like forests and coastal areas where there is an abundance of fresh, clean air.
