Stay away from high voltage power lines outdoors and electrical distribution panels indoors. If you are uncertain as to whether you think the effects of ELF are real, read the two review articles and look at the links below, or read more about measuring electric and magnetic fields . The National Institute of Environmental Health Sciences has recently issued a report entitled Assessment of Health Effects from Exposure to Power-Line Frequency Electric and Magnetic Fields . This an important summary report and should be read by everyone concerned about EMFs. The U.S. Environmental Protection Agency's EMF Infoline number is 800 363-2383.
EMFs are invisible lines of force that surround all electric devices and wiring.
Their strength increases with the current running through the devices or wires. Everyone's heart rate changes slightly from beat to beat, reflecting fine tuning by the nervous system in response to respiration and other factors, explains Sastre, a cardiovascular physiologist. Yet the magnitude of variance can differ dramatically between individuals, he notes. In the February 1998 Bioelectromagmetics, Sastre's team reported a slowing in the low spectral band among men exposed to magnetic fields that cycle on and oil every 15 seconos for an hour at a time. When David A. Savitz, an epidemiologist at the University of North Carolina at Chapel Hill, learned of the findings, he invited Sastre to help him sift through data on heart-disease deaths within the large group of electrical workers.
