AC Electric Fields - What are they?

  • Produced by the presence of electricity, and a voltage difference between two points. Their strength is determined by voltage; the higher the voltage or number of sources, the stronger the field.  AC Electric Fields are generated by live electrical wires and generally travel 6-8 feet from the source, but in some cases further.  An electric field will exist even when a device is not in use (turned off). In other words, these sources produce a continual emission.  AC Electric Fields have a natural attraction to ground and are considered low frequency electromagnetic radiation (5 Hz – 400,000 Hz)

  • Examples: Home wiring and wiring errors, power lines, AC/DC converter, lamps, extension cords, most plug-in appliances.

    1. Effects of extremely low frequency electromagnetic field (ELF-EMF) on cytokines of innate and adaptive immunity

      1. According to the studies, it is supposed that short-term (2-24 h/d up to a week) exposure of ELF-EMF with strong density may increase innate immune response due to an increase of innate immunity cytokines. Furthermore, long-term (2-24 h/d up to 8 years) exposure to low-density ELF-EMF may cause a decrease in adaptive immune response, especially in Th1 subset.


    2. The effect of chronic exposure to extremely low-frequency electromagnetic fields on sleep quality, stress, depression and anxiety

      1. This study suggests that long-term occupational exposure to ELF-EMF may lead to depression, stress, anxiety and poor sleep quality.
