The following newspaper article,  distress signals, by Tyler Hamilton, appeared in the Toronto Star, at Friday, November 11, 2005. It examines the phenomena called ES (Electrical Sensitivity) , or EHS (Electro HyperSensitivity) , and its known solutions.

Case study reports

Pre-Study Complaints

• Difficulty going to sleep
• Wake up 2-3 times a night for last 3 years
• Muscle cramps in legs
• Chronic muscle pain through-out body (myofacial)
• Hot flashes

End of Study Reports

• “Fall asleep faster and easier”
• “My neck pain is lessened”
• “My leg and foot cramps have lessened”
• “Arm and lower back pain were gone by the very first week”
• “TMJ problem significantly improved”
• “Reduction in hot flashes”

Pre-Study Complaints

Since it has been found that electromagnetic fields can affect health, researchers have investigated these phenomena in vivo and in vitro, in animals^10,11,12 and humans.^{1,2,3,4,5,6,7} No individual had been specifically challenged in an attempt to reproduce acute symptoms until Smith and Monro⁵ followed by Choy, Monro, and Smith,⁸ who used a series of oscillators of varying frequency to trigger symptoms in electrically sensitive patients. We modified this procedure by developing controlled environmental area,

Interaction mechanisms that underlie the health and biological effects of electromagnetic fields (EMF) on humans have been studied by many authors.^1,2,3,4,5,6 This subject was reviewed recently at the 1990 spring meeting of the American Physical Society .⁷ Choy et. al.⁸ investigated individuals with multiple sensitivities who reported reactions to various types of electrical equipment, including power lines, electronic office equipment such as typewriters and computer terminals, video display terminals, household

• Phase I.
  The EMF measurements were quite reproducible. We found that the lights. and air handling equipment had to be off during the tests because of their electromagnetic field output. Baseline studies on patients were completed without remarkable result.
• Phase II.

Abstract

A multiphase study was performed to find an effective method to evaluate electromagnetic field (EMF) sensitivity of patients. The first phase developed criteria for controlled testing using an environment low in chemical, particulate, and EMF pollution.
