Microwave Sickness

Front. Public Health, 20 December 2022

More recently, medical researchers have found further evidence to establish electromagnetic hypersensitivity as a real condition:

• Environmental factors implicated: Electromagnetic hypersensitivity often occurs after prolonged exposures to electromagnetic fields at work or after medical examinations using X-rays or strong magnetic fields (48);

• General sensitivity to toxins: People with electromagnetic hypersensitivity have more frequent common colds, are more sensitive to chemicals, and are more likely to be affected by environmental factors such as car exhaust and dental amalgam (49);

• Neurological damage: Consistent evidence of physiological damage to nerves associated with using a mobile phone has been found by medical researchers (5051);

• Brain changes: People with electromagnetic hypersensitivity show different fMRI patterns (52);

• Biomarkers: Blood and saliva tests for diagnosing electromagnetic hypersensitivity are used by doctors aware of the condition, e.g., histamine levels are used to indicate inflammation, and serum malondialdehyde level is used to indicate oxidative stress from cell damage (5354);

• Not psychosomatic: A large proportion of people with electromagnetic hypersensitivity are not cognisant of any harm from radiofrequency prior to experiencing symptoms (4055). Thus, an “expectation of harm” i.e., nocebo effect cannot be used as the explanation for the condition.

Electromagnetic hypersensitivity: The canaries in the coal-mine

Some individuals suffer noticeable symptoms when exposed to radiofrequency or electromagnetic fields from telecommunications systems, electronic devices or electrical wiring. These symptoms are highly varied yet relate to classical symptoms of “microwave sickness” (39) which sufferers attribute to exposures to radiofrequency emitting devices or cell towers. 

These symptoms include headaches (not the typical headache), head pressure, chest pressure, dysesthesia (skin irritation) and paraesthesia (tingling, prickling, burning sensations), insomnia, concentration difficulties, tinnitus (ringing in the ears), memory issues, dizziness, heart problems such as arrhythmia/palpitations/tachycardia, anxiety, joint pain, chronic fatigue, muscle pain and dermatological effects such as rashes (4042).

“Electromagnetic hypersensitivity” (EHS) is the common term used to describe this condition. It is classified in the International Classification for Diseases, ICD-10, under category W90: Adverse health effects of exposure to RF-EMR (43). The WHO recognizes electromagnetic hypersensitivity as “idiopathic environmental intolerance” (44) but not the cause, and in Sweden it is recognized as a functional impairment (45).

Before mobile phones existed, Frey (46) found robust evidence that humans have a sensory system tuned to microwave frequencies. Moreover, these frequencies induced blood-brain barrier penetration and altered the brain’s opiate-dopamine system, likely causing the headaches reported by Frey’s research participants (47). Frey concluded that a person reporting headaches from mobile phone exposures might be a canary in the coal mine warning of other biological effects [47, p. 102].

The Oceania Radiofrequency Scientific Advisory Association (ORSAA) has developed the world's largest categorized database of scientific studies on the biological and health effects of electromagnetic fields on humans, animals and the environment

Front. Public Health, 20 December 2022

The research papers in ODEB have been classified by ORSAA into major biological and health effects categories. The main categories discussed in the literature and used within ODEB are:

• DNA and cell damage in the brain, blood, body organs, immune and reproductive systems;

• Increased production of free radicals leading to a state of oxidative stress, and resulting in accumulated damage throughout the body;

• Neurodegeneration and blood-brain barrier breaches;

• Changes to neurotransmitter levels and signaling pathways in the brain;

• Damage to sperm and ovaries;

• Endocrine system effects;

• Damage to cellular systems and components such as mitochondria, mast cells and alterations to cellular signaling systems.

Damage to these processes underlies many health conditions.



Evidence base

Front. Public Health, 20 December 2022

Health clinicians and policy makers must be assured that sound science is behind any claims that RF is an environmental stressor. The first section of this overview paper addresses this need, by summarizing the current scientific and medical evidence base that explores biological harm from everyday devices and wireless infrastructure in the built environment.

NTP study on wifi and cell phone cancer

NIH NTP Study Demonstrates Cell Phone Cancer Link Dr. Ronald Melnick

NTP study

What did the studies find?

NTP uses a standard scale (graphic of NTP’s Level of Evidence Rating System for Cancer Studies) to determine the strength of the evidence for an association between the exposure and findings in the tissues or organs studied. The scale ranges from the highest rating of “clear evidence,” followed by “some evidence,” then “equivocal evidence,” and finally “no evidence.” Different organs or tissues can have different conclusions.

The NTP studies found that high exposure to RFR (900 MHz) used by cell phones was associated with:

  • Clear evidence of an association with tumors in the hearts of male rats. The tumors were malignant schwannomas.

  • Some evidence of an association with tumors in the brains of male rats. The tumors were malignant gliomas.

  • Some evidence of an association with tumors in the adrenal glands of male rats. The tumors were benign, malignant, or complex combined pheochromocytoma.


Wi-Fi is an important threat to human health

  • 7 effects have each been repeatedly reported following Wi-Fi & other EMF exposures.

  • Established Wi-Fi effects, include apoptosis, oxidat. stress &:

  • testis/sperm dysfunct; Neuropsych; DNA impact; hormone change; Ca2+ rise.

  • Wi-Fi is thought to act via voltage-gated calcium channel activation.

  • One claim of no Wi-Fi effects was found to be deeply flawed.



Repeated Wi-Fi studies show that Wi-Fi causes oxidative stress, sperm/testicular damage, neuropsychiatric effects including EEG changes, apoptosis, cellular DNA damage, endocrine changes, and calcium overload. Each of these effects are also caused by exposures to other microwave frequency EMFs, with each such effect being documented in from 10 to 16 reviews. Therefore, each of these seven EMF effects are established effects of Wi-Fi and of other microwave frequency EMFs. Each of these seven is also produced by downstream effects of the main action of such EMFs, voltage-gated calcium channel (VGCC) activation. While VGCC activation via EMF interaction with the VGCC voltage sensor seems to be the predominant mechanism of action of EMFs, other mechanisms appear to have minor roles. Minor roles include activation of other voltage-gated ion channels, calcium cyclotron resonance and the geomagnetic magnetoreception mechanism. Five properties of non-thermal EMF effects are discussed. These are that pulsed EMFs are, in most cases, more active than are non-pulsed EMFs; artificial EMFs are polarized and such polarized EMFs are much more active than non-polarized EMFs; dose-response curves are non-linear and non-monotone; EMF effects are often cumulative; and EMFs may impact young people more than adults. These general findings and data presented earlier on Wi-Fi effects were used to assess the Foster and Moulder (F&M) review of Wi-Fi. The F&M study claimed that there were seven important studies of Wi-Fi that each showed no effect. However, none of these were Wi-Fi studies, with each differing from genuine Wi-Fi in three distinct ways. F&M could, at most conclude that there was no statistically significant evidence of an effect. The tiny numbers studied in each of these seven F&M-linked studies show that each of them lack power to make any substantive conclusions. In conclusion, there are seven repeatedly found Wi-Fi effects which have also been shown to be caused by other similar EMF exposures. Each of the seven should be considered, therefore, as established effects of Wi-Fi.


Millimeter (MM) wave and microwave frequency radiation produce deeply penetrating effects: the biology and the physics

Pub Med 2021


Millimeter wave (MM-wave) electromagnetic fields (EMFs) are predicted to not produce penetrating effects in the body. The electric but not magnetic part of MM-EMFs are almost completely absorbed within the outer 1 mm of the body. Rodents are reported to have penetrating MM-wave impacts on the brain, the myocardium, liver, kidney and bone marrow. MM-waves produce electromagnetic sensitivity-like changes in rodent, frog and skate tissues. In humans, MM-waves have penetrating effects including impacts on the brain, producing EEG changes and other neurological/neuropsychiatric changes, increases in apparent electromagnetic hypersensitivity and produce changes on ulcers and cardiac activity. This review focuses on several issues required to understand penetrating effects of MM-waves and microwaves: 1. Electronically generated EMFs are coherent, producing much higher electrical and magnetic forces then do natural incoherent EMFs. 2. The fixed relationship between electrical and magnetic fields found in EMFs in a vacuum or highly permeable medium such as air, predicted by Maxwell’s equations, breaks down in other materials. Specifically, MM-wave electrical fields are almost completely absorbed in the outer 1 mm of the body due to the high dielectric constant of biological aqueous phases. However, the magnetic fields are very highly penetrating. 3. Time-varying magnetic fields have central roles in producing highly penetrating effects. The primary mechanism of EMF action is voltage-gated calcium channel (VGCC) activation with the EMFs acting via their forces on the voltage sensor, rather than by depolarization of the plasma membrane. Two distinct mechanisms, an indirect and a direct mechanism, are consistent with and predicted by the physics, to explain penetrating MM-wave VGCC activation via the voltage sensor. Time-varying coherent magnetic fields, as predicted by the Maxwell-Faraday version of Faraday’s law of induction, can put forces on ions dissolved in aqueous phases deep within the body, regenerating coherent electric fields which activate the VGCC voltage sensor. In addition, time-varying magnetic fields can directly put forces on the 20 charges in the VGCC voltage sensor. There are three very important findings here which are rarely recognized in the EMF scientific literature: coherence of electronically generated EMFs; the key role of time-varying magnetic fields in generating highly penetrating effects; the key role of both modulating and pure EMF pulses in greatly increasing very short term high level time-variation of magnetic and electric fields. It is probable that genuine safety guidelines must keep nanosecond timescale-variation of coherent electric and magnetic fields below some maximum level in order to produce genuine safety. These findings have important implications with regard to 5G radiation.

Keywords: 5G modulating pulses; EMF pathophysiological and therapeutic effects; coherent electronically generated EMFs; increased [Ca2+]i and calcium signaling; modulating pulses and biological EMF effects; penetrating effects via time-varying magnetic field penetration.


WiFi Related Radiofrequency Electromagnetic Fields Promote Transposable Element Dysregulation and Genomic Instability in Drosophila melanogaster


Published: 13 December 2022

“Our findings provide evidence that WiFi related RF electromagnetic fields can induce reactive oxygen species (ROS) accumulation, genomic instability, and behavioural abnormalities. Finally, we demonstrate that WiFi radiation can synergize with RasV12 to drive tumor progression and invasion. All together, these data indicate that radiofrequency radiation emitted from WiFi devices could exert genotoxic effects in Drosophila and set the stage to further explore the biological effects of WiFi electromagnetic radiation on living organisms.”
