Radiation from Cordless Phones Causes Heart Irregularities, According to New Research Published Today in the European Journal of Oncology

October 23, 2010. Boulder, CO. Cordless phones, which transmit a similar pulsed signal as Wi-Fi networks at 2.4 Gigahertz, have been shown to impact heart rate in new research published today in the European Journal of Oncology.


The double-blind, peer reviewed study validates the condition complained of by increasing numbers of people across the globe today called ‘electrosensitivity’, demonstrating immediate effects on heart rate, almost doubling the heart rate in some cases. The study, “Provocation Study using Heart Rate Variability Shows Radiation from 2.4 GHz Cordless Phone Affects Autonomic Nervous System” (Eur. J. Oncol. Library, vol. 5) was led by Prof. Magda Havas, PhD of the Environmental & Resources Studies Department at Trent University, Canada. Co-investigators included Jeffrey Marrongelle, Bernard Pollner, Elizabeth Kelley, Camilla R.G. Rees and Lisa Tully.

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.

Havas’ new study adds to the growing interest in the health effects of cell phones, which also transmit microwave radiation, broadening the focus beyond cell phones’ association with brain tumors to their potential effect on other systems, including the heart. It also raises serious concern about risks of exposing schoolchildren to Wi-Fi networks, providing a possible explanation for why some children in schools with Wi-Fi are being diagnosed with, and medicated for, heart irregularities that they believe may linked to Wi-Fi.

“What we found is what many people have said for a long time about devices that emit microwaves,” stated Dr. Havas. “People don’t just feel ill, their heart begins to race and this is measurable with medical heart monitoring devices.”


In the image below, from the study “Provocation Study using Heart Rate Variability Shows Radiation from 2.4 GHz Cordless Phone Affects Autonomic Nervous System” by Havas et al, Subject B experienced an increase in heart rate on exposure to a nearby portable phone. The heart rate immediately returned to the baseline after the cordless phone was unplugged.

Havas’ study in the European Journal of Oncology on heart rate variability was blinded, which means that the volunteers did not know when the phone was on or off. Forty percent (40%) of subjects had a moderate to severe reaction only when the phone’s base station was on, and emitting microwaves. Those who responded experienced arrhythmia (irregular beats of the heart) and/or tachycardia (rapid heart rate). The symptoms were often accompanied by feelings of pain or pressure in the chest and anxiety that would appear and disappeared for no apparent reason.

This is the first study documenting immediate and dramatic changes in heart rate associated with microwave radiation exposure at levels of exposure well below (0.5%) federal guidelines in Canada and the United States (1000 microW/cm2). It points to the extraordinary inadequacy of current exposure guidelines to protect the public’s health.

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 heralds the ability of health practitioners to determine if cardiac irregularities might be triggered by electromagnetic radiation, using readily available assessment technology, before resorting to invasive or chemical symptom-suppressing cardiac therapeutics.


Dr. Havas is a world-renowned expert in electromagnetic fields. Her teaching and research is concerned with the biological effects of electromagnetic pollution including radio frequency radiation, electric and magnetic fields, dirty electricity and ground current. She is author of the BRAG Antenna Ranking of Schools Report, which teaches schools how radiation exposure from neighborhood cell phone towers and antennas can be assessed and remediated, Zory’s Archives, an ongoing review of thousands of recently released studies on the biological effects of electromagnetic fields, dating back over a half century, drawn from U.S. government and military, and Russian and Eastern European, sources, and co-author of “Public Health SOS: The Shadow Side of the Wireless Revolution”.

On November 18th in San Francisco, Dr. Havas will present research at the Commonwealth Club of California demonstrating schools that use Wi-Fi may be putting students at great risk. The half-day program, “The Health Effects of Electromagnetic Fields”, will feature experts from the U.S., Canada, Sweden, Norway and the U.K. They will review the state of the current science showing biological effects from cell phones, cell towers, wireless networks, dirty electricity and radiation-emitting ‘Smart Meters’. A case will be presented for revision of worldwide exposure guidelines for radiation-emitting technologies. (www.commonwealthclub.org)
