Far Infrared is the ‘warm’ energy in humans, animals and plants, also emitted from sunlight. The intensity of Far Infrared produced by the human body constantly fluctuates. When its intensity is high, we feel healthy and are able to overcome ailments. When the Far Infrared (FIR) begins to decline, we are subject to disease and illness and tend to age more quickly. We can be exposed to Far Infrared heat for hours and it will never cause our skin to burn. Far Infrared heat is completely healthy and safe for all living things.
