Symptoms

The reported symptoms are generally non-specific and no consistent set of symptoms has been identified yet (WHO 2004, Workshop on EHS in Prague). Some subjects experience only symptoms if they are exposed to a specific exposure source; others claim sensitivity to a range of exposure sources (Health Protection Agency, HPA, UK).

Different symptoms like headache, sleep disorder, dizziness, fatigue, concentration difficulties, tiredness, nausea or heart palpitations are often reported in association with different exposure sources (mobile phones, base stations, power transmission lines, radar, household devices). Occasionally, muscle pain or otorhinolaryngological symptoms are reported (e.g. tinnitus, hearing problems).

In work environments with visual display units (VDUs) and nearby fluorescent lights, mainly skin symptoms (redness, tingling, burning sensations) and eye symptoms (burning) are reported.

In many cases, the intensity of the electromagnetic fields that seem to trigger symptoms of electrosensitivity is far below observed values known to cause physiological changes in scientific studies.
