We live in an electrified world. A day without electricity no longer seems possible but the conveniences requiring it have a downside. Increasingly, the negative side effects or electrosmog is a concern. Electrosmog, is the sum of man-made, electrical and electromagnetic fields affecting the environment. This can include power lines, mobile communications, radio waves, radar, computer monitors and simple household appliances.
Sources of electrical and electromagnetic fields
Electrical fields occur wherever there is a difference in voltage. In contrast, electromagnetic fields are created when current flows. A change in the charge direction, as with AC, is an alternating field. AC fields are divided by their low and high frequency alternating fields. Low-frequency alternating fields are generated, for example, by high-voltage lines, railroad and power lines, and also by common household appliances. Radio and television transmitters, radar stations and mobile antennas emit high-frequency alternating fields.
Effects of electrosmog:
High-frequency radiation can be absorbed by body tissue, which may result in the tissue over heating. This is the effect used in microwave ovens. A mobile phone may cause overheating of body tissue in the head, however the distribution is not uniform.
Besides heating body tissue, radiation absorption also affects intracellular processes, the permeability of cell membranes as well as increasing hormones (melatonin). In addition the nervous system, brain and cardiovascular system are directly influenced.
Although numerous studies have demonstrated that both high and low frequency alternating fields affect biological systems, proving a connection between the incidence of electromagnetic pollution and disease is difficult. This could be due to the complexity of our everyday reality and that of living organisms. This information is considered and acknowledged in the limits set for electromagnetic pollution. However, there is still too little documentation for it to be assessed accurately.
Electrosmog cause changes in our body; following some associated health problems to high levels of electromagnetic fields:
- Leukaemia in children
- Other types of cancer
- Fertility & pregnancy problems
- Immune system impairment
- Disturbed sleep
- Loss of memory
- Central nervous system
- Skin problems
- Children behavioural problems
How to reduce electrosmog in a home:
- Keep the bedroom area free of main electrical lines and equipment. A main electrical switch can be installed instead.
- If the installation of an electrical switch is not possible, sleep at a distance of one to two meters from electrical lines and equipment.
- Do not use electrical appliances in the bedroom for example an electronic alarm clock.
- Computers, microwave ovens and other transformer operated electric devices should be avoided as much as possible, since they produce very large alternating fields.
- Once electrical appliances are turned off they still emit a voltage that may cause an electrical field.
- In any new construction or renovation use only shielded power cables.
- Use only electric appliances with three-wire grounded plugs.
- The main power supply for a house should not be near the living area.
- Instead of wireless Internet use network adapters and the power grid.
- Electric floor heating is not recommended.
- Keep power lines at a distance of 200 meters from the home.
- Power supply lines to homes – underground, not on roof racks.
