Can energy damage the body directly?

So far its been perceived that energy effects the body in many different ways. Environmental pollution gets into the program that controls how the DNA works. Energy from insect bites and toxic bacteria stops the immune system from working properly. Something damages the outer conduit of the energy communication system which may well lead to motor neurone disease, but this is all indirect damage - energy damaging energy or changing the way the energy works, but can adverse or harmful energy cause direct damage such as the brain as in parkingson's disease and the myelin sheaths as in multiple sclerosis?

It seems it must do but the link hasn't been perceived yet. The damage is done deep down where energy, which doesn't register on a meter like electricity, but can be affected by material force or substance, meets matter in the body which is very close to being energy. An example of such a material would be petrol which is just over the line between matter and energy. There must be similar substances in the body which can be seen as matter but are mostly energy and can therefore be damaged directly by energies that are material enough. This would be the brain cells and the myelin sheaths as mentioned above. It has to be this way as how else can the damage be done? And what's doing it?

It seems clear that the damage caused to the body is a side effect of the harming energy. It has no desire , intention or need to cause this harm. It doesn't act in a malicious way, but its a side effect of its nature. For instance an acid type energy would burn through the myelin sheaths and a different energy would damage the brain cells. The burn through of the myelin sheaths seems to be an aspect of acid energy, say vinegar or acetic acid whereas the damage to the brain cells seems to have more of a clearing action, like something is trying to make room for something else. This would be the action of some kind of insect material or energy.

Also unclear is how these energies make the long journey from the outside world to certain spots or sites in the body. And why does the burn through only happen with the myelin and not elsewhere. Something carries this energy to the site of the damage a carrier energy. Have to look closer at this...
