Electrohypersensitivity or EHS is a physiological condition. It is characterized by neurological and immunological symptoms that noticeably flare or intensify upon, or following expose to:

Having Electromagnetic Field Sensitivity means experiencing recurring stress or illness when near active EMF sources or emitters of EMR. Symptoms normally diminish with distance from these sources but typically require considerable time to vanish after exposure. The World Health Organization identifies this collection of symptoms and triggers as Electrohypersensitivity, often referred to as Electrosensitivity. It is not recognized as a medical diagnosis. However, it is accepted as a functional impairment in Sweden and the Canadian Human Rights Commission recognizes it as an environmental sensitivity and classifies it as a disability.

Likely Causes

Excessive exposures to EMF or EMR from power lines, cell phone transmission towers, cell & digital cordless phones, computers, fluorescent lights and various electrical tools & equipment.

Similarly, a synergistic effect involving heavy metal buildup in the body has been reported. Predisposing genetic factors, such as the inability to excrete heavy metals, have a role in this. Common sources of heavy metal exposure are mercury in dental amalgam, aka "silver fillings", and some vaccines.

EHS is frequently seen in people with multiple chemical sensitivities (MCS), resulting from overexposure or intolerance to certain chemicals.

Common Symptoms

Four Stages of Electrohypersensitivity

  1. Mild combinations of some of the common symptoms - typically headaches, concentration & memory problems - while working with electronic equipment.
  2. Longer lasting symptoms after working with electronic equipment. Similar reactions in the vicinity of transmission towers and relay antennae. Symptoms often require medical care.
  3. Inability to work full-time; frequent sick leaves taken to cope with symptoms.
  4. Acute adverse reactions from electromagnetic pollution, both in outdoor and indoor environments. Results in unemployment and severe curtailment of freedom. Requires expensive reengineering of home environment or relocation to spartan, EMF/EMR-free rural or wilderness areas.

Prevention Tips from the EHS Community

Because the body of evidence is only now being taken seriously, most family practitioners are still unaware of EHS or anything that is involved in treating it.
If you have, or believe you may have EHS, we have prepared an information package to help you talk to your doctor about it. Please see: Talking to Your Doctor. Take a printed copy with you, to your next appointment with him/her.
