Study Shows Wi-Fi Signals Affect Heart Rate

October 26, 2010 – Cordless phones, which transmit a similar pulsed signal as Wi-Fi networks at 2.4 gigahertz, have been shown to impact heart rate according to new research published in the European Journal of Oncology.

The study validates the complaints of “electrosensitivity” by increasing numbers of people across the globe, and demonstrated immediate effects on heart rate, in some cases causing it to almost double.

“What we found is what many people have said for a long time about devices that emit microwaves,” said professor Magda Havas, Ph.D., of the environmental and resources studies department at Trent University, Canada, and leader of the study. “People don’t just feel ill, their heart begins to race and this is measurable with medical heart monitoring devices.”



The volunteers did not know when the phone was on or off and 40 percent 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.



Havas’ study adds to the growing interest in the health effects of cell phones, which also transmit microwave radiation. It also raises serious concern about risks of exposing schoolchildren to Wi-Fi networks, providing a possible explanation for why some children in schools are being diagnosed with, and medicated for, heart irregularities that they believe may linked to Wi-Fi.

“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,” Havas said. “Cordless phones and cell phones as well as wireless computers and Wi-Fi networks generate this form of microwave radiation.”



Additional symptoms include headaches, fatigue, difficulty concentrating, poor short-term memory, difficulty sleeping, skin problems, tinnitus, nausea and dizziness.
