In een blind provocatief onderzoek in Canada bleken enige personen onmiddellijk te reageren met hartonregelmatigheden als zij blootgesteld werden aan de straling van een DECT telefoon. Deze resultaten zouden uitzicht kunnen bieden op een zgn. markersysteeem voor huisartsen om bij personen de (over)gevoeligheid voor elektromagnetische velden eenvoudig vast te kunnen stellen.

Magda Havas, PhD to Present Research Demonstrating Increased Heart Rate from
Wireless Radiation Exposure at the EMR Policy Institutes Conference in Golden, CO,

Dr. Magda Havas, Professor of Environmental and Resource Studies at Trent University, Canada will present new evidence validating electrohypersensitivity at a conference organized by the EMR Policy Institute in Golden, CO this Sunday. To register contact EMR Policy Institute Vice President, Deb Carney at (303) 526-9666 or

Havas' 25-person study, which took place in Boulder and Golden, CO last October, is part of a 100-person study examining the heart's reactivity to microwave radiation emitted by common DECT cordless phones. This is the first time such striking effects from microwave radiation being emitted by wireless phones has been documented scientifically in a double blind study and it is important information for health practitioners to know. Patients today experiencing electrohypersensitivity symptoms are commonly put on drugs for other conditions with similar symptoms, instead of being taught how to create an electromagnetically clean environment to eliminate symptoms.

Symptoms of electrohypersensitivity include headaches, difficulty concentrating, insomnia, heart irregularities and much more. (See EHS Quiz at Radiation emitted from DECT portable phones is the same microwave radiation as emitted by cell phones. Havas's new study will add to the growing interest in the health effects of cell phones, broadening the focus beyond cell phones association with brain tumors to their effect on other systems, including the heart.

Havas' study on heart rate variability was blinded, which means that the volunteers did not know when the phone was on or off. Most of the volunteers did not respond to the exposure, but those who did respond experienced arrhythmia (irregular beats of the heart) and/or tachycardia (rapid heart rate). These symptoms were often accompanied by feelings of anxiety.

Havas states, ''While not everyone who is electrically sensitive responds in this manner, those who do will have difficulty being in environments where microwave radiation is present, which is virtually everywhere in our modern, wireless culture.'' She adds, ''Cordless phones and cell phones as well as wireless computers and wi-fi networks generate this form of microwave radiation.''

Additional symptoms of EHS include headaches, fatigue, difficulty concentrating, poor short-term memory, difficulty sleeping, skin problems, tinnitus, nausea, and dizziness. Many of these symptoms are subjective and difficult to measure.

Havas' study, to be presented at the conference in Golden, CO this Sunday, heralds the ability of health practitioners to determine if cardiac irregularities might be triggered by electromagnetic radiation before resorting to invasive or chemical symptom-suppressing cardiac therapeutics. She and co-investigator Jeff Marrongelle, DC of Schuylkill Haven, PA will also present the findings at the American Holistic Medical Association conference in Cleveland, OH this Friday, November 6th.

Dr. Havas is a world-renowned expert in electromagnetic fields. Her current research is concerned with the biological effects of electromagnetic pollution including radio frequency radiation, electromagnetic fields, dirty electricity and ground current. She is co-author, with Camilla Rees, of the new book, ''Public Health SOS: The Shadow Side of the Wireless Revolution'' (Amazon:
