Unlike shorter waves such as X-ray waves, infrared waves have a very positive effect on humans. Infrared heating is warmth that we were designed for. Radiant heat is part of the natural light spectrum of sunlight and a safe form of energy that heats objects by a process called direct light conversion. Radiant heat warms objects around it without affecting the temperature of the surrounding free air.
All warm blooded animals emit infrared heat, a beneficial and essential form of energy that has the ability to penetrate, refract, radiate and reflect.
The infrared radiation which is emitted from the heating units reach an object in the room (walls, ceilings, floors, interior objects) and is either absorbed by them or reflected. In turn, the infrared waves which are reflected by an object touch other objects until the waves are completely absorbed.
