What are the infrared?

Infrared rays were discovered in 1800 by the physicist William Herschel. He put a mercury thermometer in the spectrum produced by a glass prism in order to measure the heat of the various bands of colored light.

He noted that the temperature of the thermometer continued to climb even after moving beyond the red end of the spectrum where there was no visible light. This was the first experiment documenting how the heat could be transmitted by an invisible form of light.

After discovering the infrared rays, many researchers and scientists continued to study its characteristics and effects and they documented the multiple benefits on humans. Sun has always been our natural supplier of infrared energy (heat) and without it living being could not survive on earth.

The radiant energy of infrared rays ( FIR ) is a form of energy that heats objects directly without heating the surrounding air by a process called "Conversion".

The far infrared rays (FIR) are a wavelength of sunlight. The infrared electromagnetic spectrum is divided into three infrared wavelengths measured in Microns.
I micron =1/1.000.000 di metri
Near Infrared: 0.76 - 1.5 micron
Medium Infrared : 1.5 - 5.6 micron
Far Infrared: 5.6 – 10 micron.
