True Full-Spectrum Infrared — Beyond Simple Heat
Unlike saunas with halogen or narrow-spectrum heat, Tosi delivers true full-spectrum infrared—near, mid, and far wavelengths that reach the body where it matters most.
Near Infrared
Enhances cellular energy, improves circulation, reduces inflammation and pain, accelerates recovery, and supports skin and tissue repair through deep tissue penetration.
Mid Infrared
Provides focused warming of muscles and soft tissues, helping improve flexibility, reduce stiffness, enhance circulation, and support deeper therapeutic relief between near-infrared surface benefits and far-infrared core heating.
Far Infrared
Delivers deep, penetrating heat that raises core body temperature, promotes intense sweating, boosts circulation, supports detoxification, and helps reduce muscle tension and chronic pain.
The Full Spectrum Effect™
Using all three infrared wavelengths together enhances the overall therapeutic effect by enhances the therapeutic impact across both deep and surface tissues.
