There had been queries going on by the World Health Organization (WHO) regarding artificial electromagnetic fields (EMF). Certain instances brought into picture the results of what exposures to them could mean and this century's radiations are definitely greater than that before. Commercialization made EMF a widespread phenomenon; not that they were ignorant to their possible adverse effects on human health.
By and large, it has been taken care of by a great deal, but not entirely. It is currently a public health concern and WHO has stepped forward (International EMF Project). Scientific evidences are being gathered in the frequency ranges (0 to 300 GHz) and the possible effects of EMF on health don't seem stellar. To fight back, WHO is on a quest for EMF exposure standards that could be acceptable internationally.
We must catch some frequency here. From extremely low frequency (ELF; power lines for example; between 0 and 300 Hz) to the higher ranges (RF; 10 MHz - 300 GHz), there come quite a few things within. Microwave ovens and radio-transmission devices, fall under the high frequencies; that include mobile phones. There is also a middle band present - the intermediate frequency (IF) region in the EMF spectrum (300 Hz - 10 MHz.) that has been found less harmful than the RF. The studies are to end yet, regarding minimizing that even further.
Frequencies are emitted by thermal and non-thermal mechanisms alike; the resulting electric and electromagnetic fields interacting with our biological systems; some of them in the lowest thresholds of exposure tolerances. Even the upper IF range contributes to the thermal damage requiring tissue to be maintained temporarily at higher temperatures. Membrane excitation results from non-thermal mechanisms (e.g. electricity), resulting in changes in membrane potential and thus, a stimulation of peripheral nerves and muscle cells. An irreversible (mostly) symptom is electroporation, which disrupts cell membranes under excessive electrical potentials and provoke tissue injury. It's a different story that controlled dosages are medically helpful.
However, there are measures that have been found useful in fighting the frequency battles; it's a fight fire with fire situation. Sounds, colors and lights - when used appropriately, may set these reactions back half-a-way or beyond. All these are different forms of frequencies that act upon the hormonal systems, the neurotransmitters and in a broader sense, on the brain's chemistry and helps healing of conditions like headaches, tinnitus (ringing/booming sensation in ear(s), fatigue, nausea, stress, poor concentration, sleep disorder, burning sensations and even skin conditions and rashes.
All of the above are caused by an improper cell functioning, which in the long run affects the blood and organ functions. The malfunction results from a reduction in the cells' permeability, making it difficult to let nutrients in and the toxins out. It increases free radicals as well and instead of water and carbon dioxide, the body starts producing hydrogen peroxide and carbon monoxide and fermenting the cells within a short while. On longer runs, DNA damage and interference in DNA repair then puts the body under state of chronic stress. It's only a counter frequency that can fight such situations.
