What should I do if I think I'm electrosensitive?

Question

I think I react to EMF — what are the sensible next steps?

Answer

See a clinician about the symptoms themselves: that is what WHO recommends and what ANSES asked French health services to be trained for, and it is the step most likely to find something treatable. In parallel, two things are worth doing because they cost little and settle facts rather than beliefs: measure your own environment so that any change you make can be checked against a number, and remove the exposures that are cheap to remove — wired network instead of Wi-Fi in the bedroom, chargers and cordless base stations away from the bed, wiring faults corrected. What the evidence does not support is spending on shielding before measuring, or treating precautionary guideline values from clinical associations as though they were health-based limits.

• Sleeping-area assessment (full four-quantity survey)

  The combined survey building-biology practice applies to a bedroom: RF power density, AC magnetic field, AC electric field and body voltage, each graded against its own band.

  Measurement protocols

• ANSES 2018 — collective expert review of electromagnetic hypersensitivity

  France's health agency reviewed the literature plus hearings with clinicians, researchers and affected people: no solid experimental evidence of a causal link, and an explicit recommendation that the suffering be treated as real and clinically managed.

  Research record

• Where should you start measuring?

  Measure all four quantities at the sleeping position first, then fix the largest measured contributor one change at a time. The best interventions are usually free.

• Do EMF protection stickers, pendants and harmonisers work?

  No — nothing passive of that kind changes a meter reading, and a phone sticker that did block signal would make the phone transmit harder.
