@ Winter, emily’s post, ALL,
“Somehow, this does not include sunlight and sun’s UV.”
Look up the difference between ionizing and non-ionizing radiation.
Further consider magnitude of any energy radiation. Some level keeps you warm, whilst higher levels causes things to be hot, and if only a little above body heat starts to cook.
By evolution living biological systems have developed ways to deal with this excess heat, thus we can live and function in 50C and for times a little higher.
There is nothing particularly magic in it.
As for direct radiative effects, we know many chemicals that come under “organic chemistry” break down in ordinary “visable light” without having to be in the various UV bands. The effect is small but over many years many plastics for instance are broken down.
The thing is the human body suffurs the same issue, but it’s constantly dying and replacing chemicals by synthesizing new ones.
As long as the bodies repair functions work, esspecially the parts to do with error correction we survive. However at some point an error will get in and get reproduced, and that is when things go wrong. What it takes to cause an error correction failure is something that is under active investigation in many labs around the world.
We also know that you can overwhelm the error correction system. The energy in UV-C destroys surface level DNA and RNA very quickly thus gives us the “anti-pathogenic” properties it has on viri, bacteria, and phages. The human body in part solves this by having layers of dead skin on the surface held there by lipids.
So an argument could be made that the use of soap and similar that causes those dead protective cells to be removed faster is not a good idea as it decreases your protection from sunlight and the higher frequencies.
As far as I’m aware nobody has yet done research into “cleanliness and cancer”. However research has been done on drivers and cancer… And it varies in “handedness” depending on which side the driving position is.
That is the parts of the body that face the windows where high angle sun can strike the body are more likely to be where cancers appear than other parts of the body.
The problem is that of those types of cancer they are all to often very easy to undergo metastasis. Which is the process where, some cells break away from the initial cancer site “primary tumour” and travel to another place in the body via one of the circulatory systems like the bloodstream.
One area of current research is how to stop metastasis, thus the cancer spreading. Thus at the very least improving life expectancy.
But the sad fact is human death by biological aging is kind of like tossing a coin. With Dementia being one face, and cancer the obverse. There will always be a few who get the rim effect and I guess that will increase as we get cancer and dementia causes sorted out and removed from our environment.
But honestly as an engineer who has suffered genuine RF burns and worked in electromagnetic fields as strong if not stronger than you get in Nuclear Magnetic Resonance Imaging”(NMRI) systems… I’m over the half century in that swamp and so far no noticable ill effects.
As for EV’s the fields are to be honest very low frequency thus the wavelengths are very long. We do know that the efficiency of a radiator is related to it’s size or loop area compared to the wavelength. Thus personal EV’s are not very efficient at radiating any EM fields they generate.
But for those “Where paranoia destroy yer” consider trains and other public transportation systems. Over all they can be quite large, if you consider the length of a train it could easily be an effective halfwave radiator down in the frequencies used by “series resonant” Switched Mode Regulators 😉
But seriously electromagnetic fields in the longer wavelengths are nothing new, nature has been saturating the Earth’s surface with them for more time than there has been known life on it. Arguably as such it may have created life.
