Athermic effect
Latest scientific cognitions teach us that all living beings have sensory perceptive systems that respond to environmental influences (climate change, poisons, etc.). Nerve cells play an important part in this. There is a multitude of sensory receptors specified to certain impulses.
These "little things" magnify impulses several times. This way, only just a couple of olfactory substances can trigger off a potential range of actions (trigger process, see Pavlov), and such cause synergetic effects;
as when speaking of "my mouth starts drooling for food".
All sensory cells (receptors) transform the impulses in an electric voltage drop (depolarisation) at the cell membrane and directly conduct them to the central nervous system, where according reactions evelop, e.g. in an effecting organ (muscle contraction, gland secretion). When this communication is disturbed by long-term influences (e.g. inductive irritant currents), the cell looses its control-function, and chaos develops (Sackman and Neher, Nobel Prize 1991).
In plain English: If you dwell long enough in electromagnetic fields (PC, TV, stove, hairdryer, engineer's cab, airplane, car…) you shouldn't wonder when, in the long run, from year to year you start to feel less and less well.
Right?
