WHAT IS INFRARED?
Infrared (IR) is a form of light energy radiated strongly by hot bodies such as people, vehicle engines and aircraft. Infrared has a frequency just below the visible spectrum of light. These bodies generate, retain and give off heat and, as such, are visible in the infrared wavelengths of light as compared to other objects in the background that do not generate heat.
Infrared radiating from these hot bodies can be used as a source of heat. For example, infrared heaters release their heat and direct it to the bodies of people positioned near the heater. Infrared saunas use infrared heat to warm up the sauna’s occupants, rather than warming up the entire inside area of the sauna.
WHAT IS INFRARED?
Far Infrared (FIR) is gaining popularity in its use in natural health care settings and is also frequently used in physiotherapy and injury rehabilitation. Garments containing Far Infrared Technology are used to help control symptoms of arthritis, and to relieve pain from injury. Infrared technology is also used in cooking and heating food by heating the objects in the infrared oven, rather than the air inside the oven.
WHAT IS INFRARED?
Infrared heating is also gaining popularity in manufacturing, where infrared heaters replace convection ovens in formation of plastic shapes, welding and print drying. Infrared heating is optimized matching the wavelength of the infrared heater or oven to the heat-absorbing factor of the material in use.
