Electro Hypersensitivity (EHS) Definition

Girl with EHS


Electro hypersensitivity is an adverse biological reaction to EMF exposure.

EHS is not a universally accepted phenomenon, despite scientific evidence supporting its existence.

In the literature, EHS is also known as:

  • Electromagnetic Hyper Sensitivity
  • Electromagnetic Sensitivity
  • electro-hypersensitivity
  • electro-sensitivity
  • electrical sensitivity
  • Idiopathic environmental intolerance attributed to electromagnetic fields (IEI-EMF)

Self-reported symptoms attributed to EHS include:

  • headaches
  • eye strain
  • dry eyes
  • blurred vision
  • facial flushing
  • tinnitus
  • nausea
  • dizziness
  • shortness of breath
  • chest pressure
  • irregular heartbeat
  • chronic fatigue
  • muscle weakness
  • aches and pains
  • fibromyalgia
  • arthritic pain
  • prickling sensations
  • finger numbness
  • sensation of burning
  • skin rash
  • itchiness
  • blotchiness
  • stress
  • depression
  • poor concentration
  • mood disruption
  • brain fog
  • memory loss
  • confusion
  • disorientation
  • disturbed sleep
  • tremors
  • back pain
  • palpitations
  • loss of appetite
  • circulatory problems

Scientific studies connec EMF exposure with these EHS symptoms:

  • DNA damage
  • cardiac neurological degeneration
  • implanted medical equipment interference (e.g., pacemakers)
  • increased arrhythmia mortality
  • cell membrane damage
  • hypertension
  • dyslipidemic (higher fat found in blood)
  • abnormal heart rate variability in babies
