Is your electric blanket safe? It has been theorized that excessnighttime exposure to electromagnetic fields may reduce theproduction of the hormone melatonin in certain women. Furthermore,reduced melatonin levels might lead to an increased risk of breastcancer. Scott Davis at Seattle's University of Washington School ofPublic Health and Community Medicine was one of the first toinvestigate links between electromagnetic fields and cancer(particularly leukemia). He has been quoted as saying, \"Electricblankets were pretty effectively re-engineered a number of yearsago. Modern-day electric blankets ? anything you buy in the storenow ? (has a different) configuration of the heating elements inthe blanket so that it doesn't produce any magnetic fields.\" Howcould the wiring in an electric blanket be designed to minimize oreliminate the production of external magnetic fields?
