It is rare to find a patient with electrical sensitivities who does not already have multiple on-
going sensitivities to chemicals, volatiles and particulates.

their electrically hypersensitive patients since 1982
What are Electrical Sensitivities?
Many persons suffer from sensitivities to certain foods and environmental chemicals which
cause them discomfort, or even in extreme cases prevent them from functioning in any
effective manner. Even the most minute amounts of these substances may on occasions
‘trigger’ reactions which are specific to each individual. Warnings regarding nuts, peanuts or
gluten are commonly found displayed on food products. When a sensitivity reaction occurs,
some regulatory system within the body has ceased to function properly and gives alarm
signals, calling for an unjustified panic reaction. Usually, it is the autonomic nervous system
(ANS) which is the first to become compromised in this way. This system controls all the
involuntary body functions. Thus, any part or function of the body might become affected by
the same allergen acting in different people which is why such effects do not show up in
Those who have already acquired several chemical hypersensitivities and which are ‘on-
going’, are at particular risk of acquiring electrical sensitivities as an additional problem. The
allergen ‘triggering effect’ may transfer from a minute amount of some chemical in the
environment to some patient-specific frequency of an electromagnetic field in the
environment. Usually, it is the same patient symptoms that continue to be ‘triggered’. It is
the frequency of the electromagnetic field that matters, once some patient-specific threshold of
intensity or field strength has been exceeded. The range of effective coherent frequencies
extends from below a thousand seconds per cycle (circadian rhythms) through audio- and
radio- and microwave-frequencies to visible light. All these effects are ‘non-thermal’: the
electrical power is insufficient to produce any significant heating. It is the frequency that
matters. In technical terms, it is the spectral power density or the watts per cycle of bandwidth
of the radiation which matters. The more precise the frequency – the less power is needed to
produce an effect.
Germany has introduced the WHO International Classification of Diseases Code T78.4 for
‘Chemical-Sensitivity Syndrome Multiple’, against which this can be reported and statistics
collected. There is no electrical equivalent WHO Classification to date but it would seem
reasonable for these cases to be recorded as a complication of the multiple chemical
sensitivities which precede the electrical sensitivities. Sweden regards electrical sensitivity as
a disability with the implication that all public places must be fit for the electrically sensitive
disabled person to be in.
The Electrical Environment
Such persons may experience problems from the natural electrical environment beyond what
is normal such as the influence of light on melatonin levels. Electrical or acoustic (even sub-
audio) frequencies from approaching weather fronts or thunderstorms may become
troublesome. Eventually, there may be a hypersensitivity to sunlight.
Fluorescent lighting and lasers at check-outs may make shopping difficult, particularly if
inhalants such as chemicals on in-store fabrics provide an initial chemical sensitisation. The
patient may experience problems when near any electrical equipment such as power lines,
radio- TV- or mobile phone transmitters, tape or DVD-recorders, computers, mobile phones,
satellites or in fact any one of the multitude of electronic devices in the modern environment.
It is not necessary for an electrical device to be active, any passive resonant circuit may
suffice; this could be the resonant frequency of a row of metal railings in the street. Persons
may become aware of actually having electrical devices malfunction when they handle them
or, even when in their vicinity.
The female characteristic is towards chronic sensitivities appearing at an early stage, resulting
in being labelled as “over-anxious”; the male characteristic is for no reaction until the onset of
a sudden and disabling crash which may result in the person becoming completely unable to
The hazard of chronic over-exposure to electrical frequencies is one of adaptation to
symptoms triggered by a particular pattern of frequencies until they become indistinguishable
from a disease condition. The problem seems to arise when the frequency pattern of a toxic
chemical in the body matches that of the person’s electrical environment. It is the frequencies
in the electrical environment which makes the body think it is under chemical attack
Typical Subjective Symptoms Relating to Electrical Sensitivities
Drowsiness, malaise and headache, mood swings, tearfulness and eye pain, poor
concentration, vertigo and tinnitus, numbness and tingling, nausea and flatulence,
convulsions, noise sensitivity, alteration in appetite, visual disturbances, restlessness,
Clinical Observations Relating to Electrical Sensitivities
Changes in respiration, heart rate changes (heart rate variability analysis is a good indicator of
the status of the ANS), eye pupil dilation, perspiration or lack of it, muscular weakness, loss
of visual acuity, speech or writing difficulties, loss of consciousness, convulsions.
At the Breakspear Hospital, about 10% of all patients with chemical, nutritional or particulate
sensitivities had acquired electromagnetic sensitivities. Tests often showed stress coming
from some common environmental frequency such as the power supply (50Hz in UK, 60 Hz
in North America) or the 2.45 GHz frequency of microwave cookers and other devices using
Patients’ reactions were triggered over a very wide range of frequencies for which at first
there was no recognisable pattern. Then it was realised that 7.8 Hz often appeared.
Measurements quickly revealed that 7.8 Hz was the endogenous frequency of the heart
acupuncture meridian. The endogenous frequencies of other acupuncture meridians also
appeared when these were under stress. The frequencies on acupuncture meridians are very
precise; for 53 heart meridian frequencies from 38 patients, the mean was 7.788 Hz (standard
deviation ± 0.92%). This frequency is used in some therapeutic or environment protection
devices and it occurs in radiation from the Schumann Bands in the upper atmosphere to
which we are all exposed.
Sensitivities to Foods and Chemicals
About 1-in-6 of a ‘population’ is usually considered to have some degree of impaired function
due to an allergic reaction to the environment or to food. Repeated exposure to a frequency
while a person is reacting to some other allergic trigger may link that specific sensitivity
pattern to that frequency, so that the same reaction is triggered on encountering either the
frequency or the allergen on a subsequent occasion. In general, the patient’s pattern of
response is the same whether the trigger is chemical, biological, particulate, nutritional or
electrical – it is characteristic of the patient.
Exposure to pesticides or herbicides seems to enhance or even create electrical sensitivities.
Formaldehyde is a very good sensitizer. Ionising radiation exposure (e.g. long-haul flights)
represents an additional stress factor. A few persons may become hypersensitive to light,
some to sunlight, or to the light of the mercury vapour spectrum, which is superimposed on
the emission from fluorescent tubes and energy-saving lamps.
Dental fillings may cause problems due to electrolytic currents between amalgam fillings containing different mixtures of metals or, between fillings and surrounding tissue. Patients
have been seen with black stains on the palate due to the electrolytic transport of mercury.
Amalgam-to-tissue contacts may detect environmental frequencies such as radio transmissions
just like a cat’s-whisker crystal set. There has been a case where a dentist heard music coming
from a patient’s mouth. The mercury toxicity frequency and a mobile phone frequency
unfortunately happen to stress the parasympathetic branch of the autonomic nervous system.
A common feature of electrical hypersensitivity is that its sufferers complain vigorously that
nobody does anything for them, such as turning off an electrical source which they know is
“triggering” their reactions but, which seems to have no effect on anyone else. When a
hypersensitivity to sunlight is acquired, the futility of this approach is realised but perhaps not
before the sufferer has become almost paranoid about these problems.
When patients have acquired a high degree of sensitivity to many factors in foods and/or the
chemical environment (multiple-sensitivities), they are very likely to have acquired an
abnormal sensitivity to their electrical environment as a part of this ‘package’ of symptoms.
It is rare to find electrical sensitivities without on-going chemical sensitivities. This electrical
sensitivity can become so severe that a person becomes incompatible with technology and
unable to function in the modern environment. Electrical sensitivity is not mutually exclusive
of other clinical conditions; it can co-exist with and even trigger physical or mental illness.
Electrical sensitivities make diagnosis and therapy more difficult. Medications may produce
abnormal responses or side effects, even chronic sensitisation to the electrical environment.
A therapy for alleviating allergic reactions is called provocation/neutralisation
therapy. It was developed from earlier work in the USA by Dr. Joseph Miller of Mobile,
Alabama, and further developed at the Environmental Health Center, in Dallas, Texas, by Dr.
W. J. Rea and at the Breakspear Hospital, Hemel Hempstead, England by its Medical
Director, Dr. Jean Monro. This therapy relies on successive serial dilutions of the substance
having in sequence the effects of stimulating and/or quelling the reactions that they produce.
This therapy is not a substitute for eventually reducing the total body loading of triggering
substances to a level that the individual can cope with which can be done by simultaneously
increasing the rate of detoxification and reducing the rate of toxin intake until the body can
function normally, assuming that the enzyme systems for detoxification are still intact.
However, while this can produce an alleviation of the symptoms and thereby assist achieving
eventual normalisation, it may not be possible to achieve this without some change in the
patient’s lifestyle. It is also labour-intensive and therefore expensive.
The general concept introduced by Dr. W. J. Rea is to seek to reduce the total body load of
stressors. Which stress factors one seeks to reduce may be a matter of choice although some
stresses are involuntary through exposure to the general environment. Dr. Rea has
demonstrated the reality of electrical sensitivities in double-blind trials1
. The equivalent
therapy for alleviating reactions to electrical frequencies involves trying to find one or more
frequencies which will turn-off the body’s abnormal frequency sensitivity. This is not a
cure but it can help stabilise the body for more effective allergy therapy. As foods and
chemicals sensitivities are brought under control and the body detoxifies itself, the electrical
sensitivities usually disappear as well. Symptoms usually disappear in the reverse order to
their appearance. However, it is worth noting that if a person is working or sleeping in a zone
of ‘geopathic stress’, which may be electrical in origin, then their problems may persist and
Reducing the Impact of the Electrical Environment
The sensitive person is best able to determine what affects them. It is impossible to get away
from the natural electromagnetic radiation from the sun, the ionosphere, the weather and the
geomagnetic field. It is almost impossible to get away from man-made electromagnetic radiation. Persons who find a deep canyon or go to the ‘out-back’ still get zapped when a
satellite comes over the horizon. The best indicators for safer places are – mobile phones do
not work, TV reception is poor and there are no overhead lines.
In the home, electricity supply meters emit large fields and may be located in a passage on the
other side of the wall from a bed-head. From where the power supply reaches the house, its
cable may run on an outside wall but, close to a bed. Power lines on overhead poles may act
as antennae for radio and microwave transmissions and channel them into the house wiring. It
is good practice to turn off all non-essential electrical circuits at night. Power frequencies
may have the same effect as daylight in the arctic summer depressing the level of melatonin
(an anti-cancer agent). Some biologically based shielding may be provided by pine trees
which have terpene problems, cacti or spider-plants.
The power supply frequencies are in effect impossible to shield with any practical measures.
Higher frequencies can be shielded by metal wire mesh, metallised fabric or aluminium foil,
although these may act as mirrors to reflect the radiation elsewhere. They can also reflect
self-radiation emitted by a person having an allergic reaction making it even worse. A very
sensitive person may react to a quantum component of the electromagnetic field called the
magnetic vector potential and this cannot be shielded2
It is rare to find electrical sensitivities without previous and ongoing chemical sensitivities. If
a person is sensitised chemically, the electrical sensitivity can be enhanced. Remember that
electronic equipment emits chemical fumes and as these may be a trigger for reactions so they
need to be ventilated. For example, a person may tolerate the electromagnetic radiation from
a television set if it is enclosed in a glass-fronted box ventilated to the outside keeping fumes
from the hot plastic out of the room.
Computers have different clock frequencies usually specified in terms of their speed of
operation. These frequencies will be sub-divided in the process of carrying out the various
computational functions. It may be possible to find a model/manufacturer whose equipment is
tolerated. The flat screen displays are likely to have less emission. The pulses emitted when a
mobile phone dials-up a number can imprint frequencies into the head if it is held against the
ear before dialling is complete.
The eye can also be a pathway for frequencies to enter the body such as when viewing TV or a
computer. Most acupuncture meridians are stimulated/stressed while viewing a light source
flashing at a frequency equal to the endogenous frequency of the meridian. Frequencies
greater than 0.05 Hz and less than 47 kHz have this effect as do strong visual patterns and
colours. The body as a whole is sensitive to resonances in its environment, so metal structures
or even electronic equipment which is not switched on may cause problems.
Computer keyboards can have a long cable or an infrared optical link to the computer unit
enabling the latter to be kept at a distance. A whole building or public area may be fitted out
with a wire-less internet link which cannot be avoided. There is software which enables one to
dictate to a computer, so that the process of typing in a lot of text can be circumvented; only
error correction and editing need be done at the keyboard.
It is rare to find a patient with electrical sensitivities who does not already have multiple on-
going sensitivities to chemicals, volatiles and particulates. To avoid becoming electrically
sensitive, one must be careful about acquiring a body load of chemicals which happen to be
toxic to you because your body cannot get rid of them quickly. Then, if the frequency pattern
of such substances happens to match a pattern of frequencies in your electrical environment
this will make the body think it is under further chemical attack. That is why only some
people are affected by their electrical environment. Engineers (chemical or electrical) work to
specifications, unless they are told that certain environmental frequency patterns cause.
