Far-infrared spectrum cabin used in the Ninth Five-Year Plan: the heating system adopts graphene carbon crystal plate, which releases far-infrared rays more intensively than the conventional infrared band, with stronger penetration and is more conducive to the vibration of human cells. Graphene carbon crystal plate emits far infrared (8- 14 micron) close to human body (9.4 micron), and cells and instruments vibrate at the same frequency, which accelerates metabolism, raises abdominal temperature, improves basal metabolic rate and improves immunity. When molecules vibrate at the same frequency, energy is absorbed and converted, forming thermal effect, deeply heating fascia layer, accelerating microcirculation, repairing tissues, improving joint pain, regulating nerves and restoring body functions.
