What is Electromagnetic Hypersensitivity?

About this episode

Electronic appliances produce electromagnetic fields – or EMFs. These devices include mobile phones and masts, Wi-Fi routers, Bluetooth speakers and smart meters, as well as power lines and even electric motors. Electromagnetic Hypersensitivity – or EHS – is a physical reaction that people can have to these EMFs. The scientific consensus international report published in the International Journal of Molecular Sciences confirms the view that EHS is a real, measurable neurological disorder, supported by biological mechanisms and markers.

As described in the report, EHS reactions can be short-term and long-term. Short-term symptoms include headaches, dizziness, nausea, memory loss, muscle pains, heart palpitations, anxiety, depression, and skin rashes. Long-term effects include cancer and infertility, along with neurological and cardiovascular harm. Short-term symptoms stop when the EMFs causing them cease, but long-term effects can be irreversible.

Some people take years to link their EHS symptoms with EMFs and an estimated 95% of people never do. There are four difficulties. Firstly, few people can feel EMFs. Secondly, reactions may not be immediate but cumulative. Reactions can be delayed over hours or days as people become increasingly ‘hyper’ sensitive. Thirdly, the same type of EMF exposure can cause different effects, depending on temperature, hunger, time of day and humidity. Fourthly, cancers and genomic damage can take years to develop, although people with EHS may feel acute symptoms within or around cancer tissues affected by EMFs.

All humans react to EMFs, but there is a wide spectrum of sensitivity, which has been known since the 1700s. About 20% of people do not react consciously, while 30% have specific conscious reactions, such as sensitivity to EMFs from LED lights. About 1.6% of people are severely affected, and an estimated 0.65% are unable to be in their workplace unless accommodations are made.

Some genetic haplotypes are nearly ten times more common in people with EHS. Children are especially sensitive neurologically.

Triggers of hypersensitivity include experiencing high EMF levels from phones, masts, smart meters, or Wi-Fi installations, along with certain viral infections and neurological conditions.

To prevent EHS, people need a safe EMF environment with non-thermal limits, as recommended by The International Commission On The Biological Effects of Electromagnetic Fields (ICBE-EMF): https://icbe-emf.org/activities/electrohypersensitivity/; and the Scientific Consensus International Report of 2021 by 32 leading experts: https://www.mdpi.com/1422-0067/22/14/7321

Welsh version

Mae offer electronig yn cynhyrchu meysydd electromagnetig – neu EMFs. Mae’r dyfeisiau hyn yn cynnwys ffonau symudol a mastiau, llwybryddion Wi-Fi, siaradwyr Bluetooth a mesuryddion clyfar, yn ogystal â llinellau pŵer a hyd yn oed moduron trydanol. Mae Hypersensitifrwydd Electromagnetig – neu EHS – yn adwaith corfforol y gall pobl ei gael i’r EMFs hyn. Mae Adroddiad Consensus Gwyddonol Rhyngwladol a gyhoeddwyd yn y International Journal of Molecular Sciences yn cadarnhau’r farn fod EHS yn anhwylder niwrolegol gwirioneddol y gellir ei fesur, gyda mecanweithiau a marciau biolegol sy’n ei gefnogi.

Fel y disgrifir yn yr adroddiad, gall adweithiau EHS fod yn rhai tymor byr a thymor hir. Mae symptomau tymor byr yn cynnwys cur pen, pendro, cyfog, colli cof, poenau cyhyrol, clecian y galon, gorbryder, iselder, a brechau croen. Mae effeithiau tymor hir yn cynnwys canser ac anffrwythlondeb, ynghyd ag niwed niwrolegol a chardiofasgwlaidd.

Mae symptomau tymor byr yn dod i ben pan fydd yr EMFs sy’n eu hachosi’n peidio, ond gall effeithiau tymor hir fod yn anghildroadwy. Mae’n cymryd blynyddoedd i rai pobl gysylltu eu symptomau EHS ag EMFs, ac amcangyfrifir nad yw tua 95% o bobl byth yn gwneud hynny.

Mae pedwar anhawster. Yn gyntaf, ychydig o bobl sy’n gallu teimlo EMFs. Yn ail, efallai na fydd adweithiau’n digwydd ar unwaith ond yn gronnol. Gall yr adweithiau gael eu gohirio am oriau neu ddiwrnodau wrth i bobl ddod yn fwyfwy hypersensitif. Yn drydydd, gall yr un math o EMF achosi effeithiau gwahanol, gan ddibynnu ar dymheredd, newyn, amser y dydd ac amlder. Yn bedwerydd, gall canserau a niwed genomig gymryd blynyddoedd i ddatblygu, er y gall pobl ag EHS deimlo symptomau acíwt yn gynt, yn enwedig o fewn neu o amgylch meinweoedd canseraidd sydd wedi’u heffeithio gan EMFs.

Mae pob bod dynol yn ymateb i EMFs, ond mae ystod eang o sensitifrwydd, sy’n cael ei adnabod ers y 1700au. Nid yw tua 20% o bobl yn ymateb yn ymwybodol, tra bod gan 30% adweithiau ymwybodol penodol, megis sensitifrwydd i EMFs o oleuadau LED. Mae tua 1.6% o bobl yn cael eu heffeithio’n ddifrifol, ac amcangyfrifir nad yw 0.65% yn gallu bod yn eu gweithle oni bai bod addasiadau’n cael eu gwneud.

Mae rhai haplotypau genetig bron 10 gwaith yn fwy cyffredin ymhlith pobl ag EHS. Mae plant yn arbennig o sensitif yn niwrolegol.

Ymhlith yr achosion cyffredin o EHS mae lefelau uchel o EMFs o ffonau, mastiau, mesuryddion clyfar neu osodiadau Wi-Fi, ynghyd â rhai heintiau feirysol ac anhwylderau niwrolegol.

I atal EHS, mae angen amgylchedd diogel rhag EMFs gyda therfynau nad ydynt yn thermol, fel y’u hargymhellwyd gan The International Commission On The Biological Effects of Electromagnetic Fields, a’r Scientific Consensus International Report o 2021 gan 32 o arbenigwyr blaenllaw.
