The human body emits light in the invisible IR range, including the hands. This source of radiation, the researchers noted, could potentially be captured and used in applications ranging from signal generation to encryption systems. They further noted that because the hand has multiple fingers, the IR that it emits could be considered to be multiplexed.
IR is a form of electromagnetic radiation—its wavelengths are longer than those of visible light, which is why humans cannot see them. Prior research has shown that the human body emits such radiation due to body heat. Electromagnetic radiation carries with it radiant energy, and its behavior is classified as both a quantum particle and a wave. Prior research has also shown that electromagnetic radiation can be used in a variety of applications, including microwaves, radios and medical imaging devices. And infrared light, in particular, enables night vision goggles, spectroscopy devices and medical devices used to treat burn victims. In this new effort, the researchers have found that the very small amount of IR emitted by the human hand is sufficient to use in various devices.
It’s talking about using the invisible (to the human eye) light from the heat source. Very interesting article.
“OMG, 45 years ago I thought my MIL was nutty for trying to cure my headache with johrei - energy emanating from her hands. (It didn’t work.)”

My grandma cured my childhood warts I had in my hands by rubbing them with a potato. Only later in life did I learn that warts are caused by a virus and usually just go away on their own.
LOL, I can occasionally “smell” snow on those miserable, gray days...
On a more realistic note, why would this be considered to be unusual, that human hands are an infrared radiation source. Anyone who has held a living hand knows that.
Now, a “powerless” source...that would be something different altogether. Humans as IR emitters are “powered”. Take away our food (power source) for a few weeks and see what our IR emissions look like.
Claude Monet could see uv light when he had a lens removed from his eye because of blinding cataracts.
Isn’t it amazing now that we know that parts of our bodies emit infrared light? Now that we’ve been using body heat detectors for what...50 years?
I got tired of visible light photography and got into IR and UV.
I can look at a scene and tell if it will make a worthy IR photo or not.
Normally that would be lots of foliage and such but there are other things that emit/reflect IR quite well and I have a weird knack for ‘seeing’ them beforehand.
UV photography is even stranger.
Full spectrum is really bizarre.
Very little of the world looks like we think it does.
If we could see what critters do, we’d go insane.
/there is something wrong with me, I think
