Dirty Electricity and Electrical Hypersensitivity: Five Case Studies

January 24, 2012April 26, 2026 April 26, 2026

Author(s): Dr. Magda Havas, BSc, Ph.D. (Professor of Environmental and Resource Studies – Trent University, Peterborough, Ontario, Canada), David Stetzer (President/CEO – Stetzer Electric, Inc. Blair, WI USA)
Presentation: Proceedings from the World Health Organization Workshop on Electrical Hypersensitivity, Prague, Czech Republic
Date: October 25-26, 2004

Abstract:
Deteriorating power quality is becoming increasingly common in developed countries. Poor power quality, also known as dirty electricity, refers to a combination of harmonics and transients generated primarily by electronic devices and by non-linear loads. We have assumed, until recently, that this form of energy is not biologically active. However, when Graham/Stetzer™ filters were installed in homes and schools, symptoms associated with electrical hypersensitivity (such as chronic fatigue, depression, headaches, body aches and pains, ringing in the ears, dizziness, impaired sleep, memory loss, and confusion) were reduced. Five case studies are presented that include one healthy individual; one person with electrical hypersensitivity; another with diabetes; and a person with multiple sclerosis. Results for 18 teachers and their classes at a school in Toronto are also presented.

These individuals experienced major to moderate improvements in their health and wellbeing after Graham/Stetzer™ filters improved power quality in their home or work environment. The results suggest that poor power quality may be contributing to electrical hypersensitivity and that as much as 50% of the population may be hypersensitive; children may be more sensitive than adults and dirty electricity in schools may be interfering with education and possibly contributing to disruptive behavior associated with attention deficit disorder (ADD); dirty electricity may elevate plasma glucose levels among diabetics, and exacerbate symptoms for those with multiple sclerosis and tinnitus. Graham/Stetzer™ filters and meters enable individuals to monitor and improve power quality in buildings and they provide scientists with a tool for studying the effects of dirty electricity. For the first time we can progress from simply documenting electrical hypersensitivity to alleviating some of the symptoms. These results are dramatic and warrant further investigation. If they are representative of what is happening worldwide, then dirty electricity is adversely affecting the lives of millions of people.
