Infrared light:
We feel it as
heat
Infrared light is a part of the electromagnetic spectrum with
longer wavelengths at high irradiance levels than visible light.
We feel it as heat: IR radiation is responsible for heat
gain in buildings, while plants and trees reflect it. It impacts
melatonin production and is most effective the first two hours
after the sun is fully risen.
It can penetrate the skin and interact with and modulate the
functions of our cells. Exposure to infrared allows the skin to
prepare for ultraviolet (decrease sunburn)
