Following is a list of the main passive devices and technologies known to affect human beings and other organisms at a biological level. By “passive”, we mean those items that do not intentionally emit electromagnetic radiation (EMR) but none the less do so anyway, often as a result of poor design. Also known as “field effects”.
- CFLs, Energy Saver or Compact Fluorescent Lights – Despite being touted as green, these bulbs are anything but. Not only are they very difficult to recycle but also a smashed bulb releases enough mercury to contaminate 12 bathtubs of water (calculation based on European safety limits) on average and should be treated as a toxic spill. They can emit focused pulses of EMR and usually flicker and give such a poor light spectrum as to confuse the eye and inhibit melatonin production at night.
Finally, as if that wasn’t enough, poor quality bulbs can disrupt the AC sine wave on a building’s mains circuit, causing wiring in that building and even nearby buildings to emit their own EMR. This phenomenon, common to some other appliances has been labelled “Dirty Electricity”.

- Computers, Televisions and other Devices – even without wireless functionality, computers and many advanced devices emit electromagnetic radiation on multiple frequencies.
- Hair dryers – Complaints of getting a headache during/after use are common.
- Transformers, Chargers and Power Supplies – Most electrical appliances cannot run directly from mains power, instead requiring a transformer to adjust the voltage to a more “digestible” level.
Unfortunately, the smaller, cheaper types (which most are) emit their own EMR as well as contributing to a building’s “Dirty Electricity” load.
- Radio Alarm Clocks – Although one of the lesser contributors to the problem, their often close proximity to the bed makes them something to avoid. Usually this is mostly the fault of the transformer inside the clock.
- Power Lines – The negative effects of high voltage overhead power lines are well known and have been profusely documented in the past.
