All biochemical functions (processes) are activated and regulated by our body's own electromagnetic fields. The fact that magnetic fields enter our body's own energy fields is well documented by biophysicists and can easily be measured.
Electromagnetic frequencies are man-made and therefore unnatural, chaotic and disordered and biophysics has established that 'Every kind of frequency combination which is not in order produces disease.' Disease occurs through a disturbance of the electromagnetic field in the cells: they become disordered and incoherent. (More later)
The affects upon our health by exposure to EMF Radiation, looking from a biochemical view point, would appear to show ill health is caused by the displacement of electrolytes/ions within the body and by interfering with the body's natural way of communicating (neurological system) and maintaining homeostasis - balance. This will weaken the defense mechanism of the body as the body expends energy attempting to redress this imbalance.
If we cannot get away from these EMF fields because we live within their field of influence, the body will be unable to correct this electrical and biochemical imbalance and, as the science of Biophysics has proven that we only become ill when the defense mechanism of the body is weakened, it follows that we will undoubtedly become ill as a direct result of living or working within these EMR fields.
So it is not a question of whether these EMF fields cause health problems or not, that is not in doubt. What is uncertain is just how this ill-health will manifest in an individual; this is determined by the individual's own constitution and health and may manifest in many ways, which is why we are seeing so many 'new' immune deficient disorders today.
