Think of the Sun!
Typically, people think of radiation as a harmful thing, but the warmth you feel from the sun’s rays is infrared heat radiation, and it is entirely safe.
Infrared heating uses a natural and safe far-infrared radiation to heat objects such as furniture and people, which in turn emit the energy back into the room as radiant heat.
Far-infrared rays that are similar to sunlight andeasily absorbed by the human body, it can penetrate into human cell tissuesand vibrate at the same frequency as the molecules and atoms in human cellsforming resonance, activating cell tissues, accelerating blood circulation, andeffectively improving human microcirculation.
