Symptomatic presentation of Electromagnetic Hypersensitivity by body system
EHS presents as a multi-system syndrome. Reported symptoms cluster within the central nervous, cardiovascular, dermatological, and autonomic systems — consistent with the condition's proposed neuro-inflammatory mechanism.
Reported symptoms by organ system
Hover any region of the anatomical figure or a card below to cross-reference. Severity ratings reflect aggregated patient-reported outcome data from EUROPAEM and ANSES clinical reviews (2016–2023).

§ 01 · Exposure
EHS is triggered by environmental radiofrequency and extremely-low-frequency (ELF) electromagnetic fields at non-thermal intensities — typically 0.001–10 V/m — well below current ICNIRP thermal safety thresholds.
§ 02 · Neurobiology
Proposed mechanisms centre on voltage-gated calcium channel hyperactivation, oxidative stress, and blood-brain-barrier permeability alteration. Evidence is contested but reproducible in animal and in-vitro models.
§ 03 · Presentation
Symptom onset typically occurs within minutes to hours of exposure and resolves in a low-EMF environment. Case-defined diagnosis requires exclusion of other conditions per EUROPAEM 2016 Guideline.
