Electromagnetic hypersensitivity (EHS) is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed. EHS has no scientific basis and is not a recognized medical diagnosis, although it is generally accepted that the experience of EHS symptoms is of psychosomatic origin. Claims are characterized by a "variety of non-specific symptoms, which afflicted individuals attribute to exposure to electromagnetic fields". [1] Attempts to justify the claim that EHS is caused by exposure to electromagnetic fields have amounted to pseudoscience. [2]
Those who are self-diagnosed with EHS report adverse reactions to electromagnetic fields at intensities well below the maximum levels permitted by international radiation safety standards. Provocation trials have found that such claimants are unable to distinguish between exposure and non-exposure to electromagnetic fields. [3] [4] A systematic review of medical research in 2011 found no convincing scientific evidence for symptoms being caused by electromagnetic fields. [3] Since then, several double-blind experiments have shown that people who report electromagnetic hypersensitivity are unable to detect the presence of electromagnetic fields and are as likely to report ill health following a sham exposure as they are following exposure to genuine electromagnetic fields, suggesting the cause in these cases is the nocebo effect. [5] [6] [7]
As of 2005 [update] , the WHO recommended that claims of EHS be clinically evaluated to determine and rule out alternative diagnoses for suffered symptoms. [1] Cognitive behavioral therapy and management of comorbid psychiatric disorders may be helpful in managing the condition. [8]
Some people who feel they are sensitive to electromagnetic fields may seek to reduce their exposure or use alternative medicine. [9] Government agencies have enforced false advertising claims against companies selling devices to shield against EM radiation. [10] [11]
There are no specific symptoms associated with claims of EHS, and the reported symptoms range widely among individuals. [1] They include headache, fatigue, stress, sleep disturbances, skin prickling, burning sensations and rashes, and pain and ache in muscles. In severe cases such symptoms can be a real and sometimes disabling problem for the affected person, causing psychological distress. [9] There is no scientific basis to link such symptoms to electromagnetic field exposure. [1]
The prevalence of some reported symptoms is geographically or culturally dependent and does not imply "a causal relationship between symptoms and attributed exposure". [12] [13] Many such reported symptoms overlap with other syndromes known as symptom-based conditions, functional somatic syndromes, and IEI (idiopathic environmental intolerance). [12]
Those reporting electromagnetic hypersensitivity usually describe different levels of susceptibility to electric fields, magnetic fields, and various frequencies of electromagnetic waves. Devices implicated include fluorescent and low-energy lights, mobile, cordless/portable phones, and Wi-Fi. [14] A 2001 survey found that people self-diagnosing as EHS related their symptoms most frequently to cell sites (74%), followed by mobile phones (36%), cordless phones (29%), and power lines (27%). [9] Surveys of people with EHS have found no consistent pattern to these symptoms. [9] [14] [15]
Most blinded conscious provocation studies have failed to show a correlation between exposure and symptoms. An example is a 2007 study where 17 individuals who showed symptoms in an open test were exposed variously to real mobile phones or sham ones. The individuals showed discomfort at the mobile phones regardless of whether the phones were genuine. [16] These results suggest that psychological mechanisms play a role in causing or exacerbating EHS symptoms. In 2010, Rubin et al. published a follow-up to their 2005 review, bringing the totals to 46 double-blind experiments and 1175 people with self-diagnosed EHS. [17] [18] Neither review found robust evidence to support the hypothesis that electromagnetic exposure causes EHS, nor have other studies. [5] [6] They also concluded that the studies supported the role of the nocebo effect in triggering acute symptoms in those with EHS. [4]
Electromagnetic hypersensitivity is not an accepted diagnosis; medically there is no case definition or clinical practice guideline and no test to identify it, nor is there an agreed-upon definition with which to conduct clinical research. [19]
Complaints of electromagnetic hypersensitivity may mask organic or psychiatric illness: in a recent psychological model of mental disorder, [20] Sébastien Point proposed to consider it as a specific phobia. Diagnosis of those underlying conditions involves investigating and identifying possible known medical causes of any symptoms observed. [1] It may require both a thorough medical evaluation to identify and treat any specific conditions that may be responsible for the symptoms, and a psychological evaluation to identify alternative psychiatric/psychological conditions that may be responsible or contribute to the symptoms. [1] [21]
Symptoms may also be brought on by imagining that exposure is causing harm, an example of the nocebo effect. Studies have shown that reports of symptoms are more closely associated with belief that one is being exposed than with actual exposure. [5] [6] [22] [23]
Whatever the cause of symptoms attributed to EHS, it can be a debilitating condition that benefits from treatment or management. [8] Cognitive behavioral therapy has shown some success helping people cope with the condition. [8]
As of 2005, WHO recommended that people presenting with claims of EHS be evaluated to determine if they have a medical condition that may be causing the symptoms the person is attributing to EHS, that they have a psychological evaluation, and that the person's environment be evaluated for issues like air or noise pollution that may be causing problems. [1]
A variety of pseudoscientific devices are marketed to those who fear that they are being harmed by electromagnetic fields. [24] The US Federal Trade Commission has warned about scams that involve selling products purported to protect against cell phone radiation. [25] [24] In the UK, a product called 5GBioShield was identified by Trading Standards as a "scam" device. Its manufacturers claimed that it could mitigate harms from phone radiation, but British authorities determined that the device was merely a USB drive. [26]
In 1997, before Wi-Fi, Bluetooth and 3G technology, a group of scientists attempted to estimate the number of people reporting "subjective symptoms" from electromagnetic fields for the European Commission. [27] They estimated that electromagnetic sensitivity occurred in "less than a few cases per million of the population" (based on centres of occupational medicine in UK, Italy and France) or up to "a few tenths of a per cent of the population" (based on self-aid groups in Denmark, Ireland and Sweden). In 2005, the UK Health Protection Agency reviewed this and several other studies for prevalence figures and concluded that "the differences in prevalence were at least partly due to the differences in available information and media attention around electromagnetic hypersensitivity that exist in different countries" and that "Similar views have been expressed by other commentators". [12] The authors noted that most of the studies focused on computer monitors (VDUs), as such the "findings cannot apply in full" to other forms of EMF exposure such as radio waves from mobile phones/base stations.
In 2007, a UK survey aimed at a randomly selected group of 20,000 people found a prevalence of 4% for symptoms self-attributed to electromagnetic exposure. [28]
A 2013 study using telephone surveys in Taiwan concluded that the rates of IEI-EMF were in decline within the country, despite previous expectations of a rise in prevalence as electronic devices became more widespread. Rates declined from 13% in 2007 to 5% in 2013. [29] The study also referred to apparent declines in the Netherlands (from 7% in 2009 [30] to 4% in 2011 [31] ) and in Germany (from 10% in 2009 [32] to 7% in 2013 [32] ). More women believed themselves to be electromagnetically hypersensitive than men. [29]
In 2021, physicist Sébastien Point noted that the prevalence of electrohypersensitivity is similar to the prevalence of specific phobias as well as the gender ratio (2 electrohypersensitive or phobic women for one electrohypersensitive or phobic man), which, according to him, reinforces the hypothesis that electrohypersensitivity is a new specific phobia. [33]
In 2010, a cell tower operator in South Africa revealed at a public meeting that the tower that nearby residents were blaming for their EHS symptoms had been turned off over six weeks before the meeting, making it a highly unlikely cause of EHS symptoms. [34]
In February 2014, the UK Advertising Standards Authority found that claims of harm from electromagnetic radiation, made in a product advertisement, were unsubstantiated and misleading. [11]
People have sued for damages due to harm claimed from electromagnetic radiation. In 2012, a New Mexico judge dismissed a lawsuit in which a person sued his neighbor, claiming to have been harmed by EM radiation from his neighbor's cordless telephones, dimmer switches, chargers, Wi-Fi and other devices. The plaintiff brought the testimony of his doctor, who also believed she had EHS, and a person who represented himself as a neurotoxicologist; the judge found none of their testimony credible. [35] In 2015, parents of a boy at a school in Southborough, Massachusetts, alleged that the school's Wi-Fi was making the boy sick. [35] [36]
In November 2015, a depressed teenage girl in England died by suicide. This act was attributed to EHS by her parents and taken up by tabloids and EHS advocates. [37]
The public position of the EU's Scientific Committee on Emerging and Newly Identified Health Risks (SCENIHR) to the European Commission is that "new improved studies on the association between radio frequency fields from broadcast transmitters and childhood cancer provide evidence against such an association." But "data on the health effects of intermediate frequency fields used, for example, in metal detectors or anti-theft devices in shops, are still lacking." The SCENIHR called for research to continue. [38]
Some people who feel they are sensitive to electromagnetic fields self-treat by trying to reduce their exposure to electromagnetic sources by disconnecting or removing electrical devices, shielding or screening their selves or residences, and alternative medicine. [9] In Sweden, some municipalities provide disability grants to people who claim to have EHS in order to have abatement work done in their homes, even though the public health authority does not recognize EHS as an actual medical condition; towns in Halland do not provide such funds and this decision was challenged and upheld in court. [39] [40] [41]
The United States National Radio Quiet Zone is an area where wireless signals are restricted for scientific research purposes, and some people who believe they have EHS have relocated there to seek relief. [42] [43] [44]
Gro Harlem Brundtland, former prime minister of Norway and Director general of the World Health Organization, claims to have EHS. [45] In 2015, she said that she had been sensitive for 25 years. [46]
The 2022 documentary Electric Malady examines the life of a Swedish man who claims to have EHS. [47]
The crime drama television series Better Call Saul , the prequel to Breaking Bad , features the character Chuck McGill, who claims to have EHS. [48]
Electromagnetic radiation can be classified into two types: ionizing radiation and non-ionizing radiation, based on the capability of a single photon with more than 10 eV energy to ionize atoms or break chemical bonds. Extreme ultraviolet and higher frequencies, such as X-rays or gamma rays are ionizing, and these pose their own special hazards: see radiation poisoning. The field strength of electromagnetic radiation is measured in volts per meter (V/m).
A tin foil hat is a hat made from one or more sheets of tin foil or aluminium foil, or a piece of conventional headgear lined with foil, often worn in the belief or hope that it shields the brain from threats such as electromagnetic fields, mind control, and mind reading. The notion of wearing homemade headgear for such protection has become a popular stereotype and byword for paranoia, persecutory delusions, and belief in pseudoscience and conspiracy theories.
The microwave auditory effect, also known as the microwave hearing effect or the Frey effect, consists of the human perception of sounds induced by pulsed or modulated radio frequencies. The perceived sounds are generated directly inside the human head without the need of any receiving electronic device. The effect was first reported by persons working in the vicinity of radar transponders during World War II. In 1961, the American neuroscientist Allan H. Frey studied this phenomenon and was the first to publish information on the nature of the microwave auditory effect. The cause is thought to be thermoelastic expansion of portions of the auditory apparatus, although competing theories explain the results of holographic interferometry tests differently.
Multiple chemical sensitivity (MCS) is an unrecognized and controversial diagnosis characterized by chronic symptoms attributed to exposure to low levels of commonly used chemicals. Symptoms are typically vague and non-specific. They may include fatigue, headaches, nausea, and dizziness.
The National Radio Quiet Zone (NRQZ) is a large area of land in the United States designated as a radio quiet zone, in which radio transmissions are restricted by law to facilitate scientific research and the gathering of military intelligence. About half of the zone is located in the Blue Ridge Mountains of west-central Virginia while the other half is in the Allegheny Mountains of east-central West Virginia; a small part of the zone is in the southernmost tip of the Maryland panhandle.
Specific absorption rate (SAR) is a measure of the rate at which energy is absorbed per unit mass by a human body when exposed to a radio frequency (RF) electromagnetic field. It is defined as the power absorbed per mass of tissue and has units of watts per kilogram (W/kg).
A nocebo effect is said to occur when a patient's negative expectations for a treatment cause the treatment to have a worse effect than it otherwise would have. For example, when a patient anticipates a side effect of a medication, they can experience that effect even if the "medication" is actually an inert substance. The complementary concept, the placebo effect, is said to occur when positive expectations improve an outcome. The nocebo effect is also said to occur in someone who falls ill owing to the erroneous belief that they were exposed to a physical phenomenon they believe is harmful, such as EM radiation.
The antennas contained in mobile phones, including smartphones, emit radiofrequency (RF) radiation ; the parts of the head or body nearest to the antenna can absorb this energy and convert it to heat. Since at least the 1990s, scientists have researched whether the now-ubiquitous radiation associated with mobile phone antennas or cell phone towers is affecting human health. Mobile phone networks use various bands of RF radiation, some of which overlap with the microwave range. Other digital wireless systems, such as data communication networks, produce similar radiation.
Hypersensitivity pneumonitis (HP) or extrinsic allergic alveolitis (EAA) is a syndrome caused by the repetitive inhalation of antigens from the environment in susceptible or sensitized people. Common antigens include molds, bacteria, bird droppings, bird feathers, agricultural dusts, bioaerosols and chemicals from paints or plastics. People affected by this type of lung inflammation (pneumonitis) are commonly exposed to the antigens by their occupations, hobbies, the environment and animals. The inhaled antigens produce a hypersensitivity immune reaction causing inflammation of the airspaces (alveoli) and small airways (bronchioles) within the lung. Hypersensitivity pneumonitis may eventually lead to interstitial lung disease.
Bioelectromagnetics, also known as bioelectromagnetism, is the study of the interaction between electromagnetic fields and biological entities. Areas of study include electromagnetic fields produced by living cells, tissues or organisms, the effects of man-made sources of electromagnetic fields like mobile phones, and the application of electromagnetic radiation toward therapies for the treatment of various conditions.
Occupational lung diseases comprise a broad group of diseases, including occupational asthma, industrial bronchitis, chronic obstructive pulmonary disease (COPD), bronchiolitis obliterans, inhalation injury, interstitial lung diseases, infections, lung cancer and mesothelioma. These can be caused directly or due to immunological response to an exposure to a variety of dusts, chemicals, proteins or organisms. Occupational cases of interstitial lung disease may be misdiagnosed as COPD, idiopathic pulmonary fibrosis, or a myriad of other diseases; leading to a delay in identification of the causative agent.
Arthur Robert Firstenberg is an American author and activist on the subject of electromagnetic radiation and health. He is the founder of the independent campaign group the Cellular Phone Task Force. He is the author of Microwaving Our Planet: The Environmental Impact of the Wireless Revolution and The Invisible Rainbow: A History of Electricity and Life.
Radiobiology is a field of clinical and basic medical sciences that involves the study of the effects of ionizing radiation on living things, in particular health effects of radiation. Ionizing radiation is generally harmful and potentially lethal to living things but can have health benefits in radiation therapy for the treatment of cancer and thyrotoxicosis. Its most common impact is the induction of cancer with a latent period of years or decades after exposure. High doses can cause visually dramatic radiation burns, and/or rapid fatality through acute radiation syndrome. Controlled doses are used for medical imaging and radiotherapy.
Idiopathic environmental intolerances (IEI) are medical syndromes with no proven cause, but which the affected people attribute to various environmental situations. The most common forms are multiple chemical sensitivity, electromagnetic hypersensitivity (electricity), and wind turbine syndrome (noise).
The BioInitiative Report is a report on the relationship between the electromagnetic fields (EMF) associated with powerlines and wireless devices and health. It was self-published online, without peer review, on 31 August 2007, by a group "of 14 scientists, researchers, and public health policy professionals". The BioInitiative Report states that it is an examination of the controversial health risks of electromagnetic fields and radiofrequency radiation. Some updated BioInitiative material was published in a journal in an issue guest-edited by one of the members of the group, and a 2012 version of the report was released on 7 January 2013. It has been heavily criticized by independent and governmental research groups for its lack of balance.
Non-ionizingradiation refers to any type of electromagnetic radiation that does not carry enough energy per quantum to ionize atoms or molecules—that is, to completely remove an electron from an atom or molecule. Instead of producing charged ions when passing through matter, non-ionizing electromagnetic radiation has sufficient energy only for excitation. Non-ionizing radiation is not a significant health risk. In contrast, ionizing radiation has a higher frequency and shorter wavelength than non-ionizing radiation, and can be a serious health hazard: exposure to it can cause burns, radiation sickness, many kinds of cancer, and genetic damage. Using ionizing radiation requires elaborate radiological protection measures, which in general are not required with non-ionizing radiation.
Fluorescent lamps have been suggested to affect human health in various ways.
Henry Lai is a bioengineering professor emeritus at the University of Washington, and editor-in-chief of Electromagnetic Biology and Medicine. Lai published research in 1995 that concluded that low-level microwave radiation caused DNA damage in rat brains.
Misinformation related to 5G technology is widespread in many countries of the world. The spreading of false information and conspiracy theories has also been propagated by the general public and celebrities. In social media, misinformation related to 5G has been presented as facts, and circulated extensively. There are no scientifically proven adverse health impacts from the exposure to 5G radio frequency radiation with levels below those suggested by the guidelines of regulating bodies, including the International Commission on Non-Ionizing Radiation Protection (ICNIRP). Furthermore, studies have shown that there is no noticeable increase in the everyday radiofrequency electromagnetic exposure since 2012, despite the increased use of communication devices.
The ability of a human brain to convince itself of just about anything is not to be underestimated. If you believe yourself to be electrosensitive, then you will be, quite literally, whenever you (think that you) perceive the presence of electromagnetism... you will actually suffer measurable physical symptoms and can potentially become acutely ill.
