Surveys of impairments, symptoms and objective markers

What is ES?


Specific Impairments and Symptoms

Typical Impairments and Symptoms include:

  • headaches
  • disturbed sleep
  • heart palpitations
  • anxiety
  • pains and tingling in limbs
  • blurred vision
  • see fuller list to right

Impairments and Symptoms can be:

  • delayed, by hours or days
  • cumulative
  • short-term or acute
  • long-term or chronic, especially for neurological and cancer effects
  • conscious
  • subconscious

Impairments and Symptoms often occur:

  • immediately after electromagnetic exposure, e.g. headache or muscle spasm, when someone nearby switches on their cellphone (conscious, acute)
  • over minutes and hours of low-level electromagnetic exposure, e.g. growing memory loss, tiredness or headaches after an hour or two in WiFi radiation (conscious, chronic)
  • perhaps 12 to 16 hours after heavy exposure, e.g. nausea, dizziness, muscle failure or cramps hours after being present in heavy usage of cellphones or radio mike exposure (conscious, delayed acute)
  • over months or years of frequent electromagnetic exposure, e.g. neurological and cancer effects like muscle wasting, degenerative conditions or skin and tissue tumor growths, from domestic cordless phones, power line cables, cellphone towers, neighbor's WiFi (conscious or subconscious, chronic) 

Impairments and Symptoms depend on:

  • genetic factors
  • presence of metals in the body (e.g. mercury dental amalgam restorations, cardiac pacemakers, metal plates and pins, tatoos with metallic colors)
  • previous exposure
  • adaptation of the body to stress from environmental toxins
  • other sources of stressors (e.g. chemical sensitivity)

Electrosensitivity is a Functional Disability causing Impairments, not an Illness or Disease

  • Electrosensitivity is a disability impairing the person's ability to function fully in society.
  • Electrosensitivity is a functional impairment to an environmental problem.
  • Electrosensitivity is therefore similar to functional disability caused by impaired access for a wheel-chair user, or by impaired access for a deaf, blind or chemically intolerant person.
  • Electrosensitivity, like other environmental intolerances, defines the toxic pollution in the environment as 'ill' or 'diseased', not the person, who is perfectly health when the toxic pollution is removed. 

Electrosensitivity is an Intolerance, not an illness or disease

  • Electrosensitivity is primarily an intolerance, not a disease.
  • The specific Impairments and symptoms of Electrosensitivity are typical of systemic intolerance or allergy reactions, not diseases.
  • There is no known virus or bacteria associated with Electrosensitivity.
  • Electrosensitivity is not communicable and cannot be transmitted to other people.
  • The 'illness' is in the environment, which is 'sick' for the person intolerant of the toxic pollution produced by electromagnetic exposure. 
  • Electrosensitivity is thus typical or other environmental Intolerances, such as to chemicals, foods, light, sound etc.
  • People with Electrosensitivity are perfectly healthy outside of a polluted environment where they react with impairments or symptoms to the toxic electromagnetic exposure.
  • Some people's Electrosensitivity is caused by another illness, such Multiple Sclerosis, or by a combination of factors, such an environmental electromagnetic pollution and the presence of metallic dental restorations, metallic implants in the body or metallic-based tattoos.

Impairments and Symptoms can be:

  • delayed, by hours or days
  • subconscious: sometimes people with ES are asymptomatic (have no conscious symptoms) even though their body still reacts to the electromagnetic exposure

Few accurate surveys of the prevalence of ES and EHS in the general population have been conducted.

For conscious symptoms:
- perhaps under 1% are affected severely
- 2% to 4% are affected significantly
- up to about 40% are affected in smaller ways, such as disturbed sleep within 500 meters of a cellphone tower.
For unconscious affects:

- about 5-10% of the general population can be affected adversely with cancers and neurological diseases depending on duration and intensity of exposure

- about 40% of adults, i.e. those with chronic immune diseases, are adversely affected.
