Question: At what point will sensitive people start feeling 'strange' effects of high EMF in their surrroundings?
This question was posed by one of our community and so we did a little bit of digging. here is what came up. ( thank you for asking Lisa) This is one of those topics where the science is actually clearer, but it gets muddied because people genuinely do experience strange things โ just not always for the reasons they think. Iโll break this into levels, time exposure, symptoms, and whoโs more sensitive. First - what weโre talking about when we say EMF Most โhaunted locationโ EMF comes from extremely low frequency (ELF) electromagnetic fields, usually: โข wiring faultsโข old electrical systemsโข transformersโข switchboardsโข appliances behind walls These are non-ionising fields โ meaning they do not damage DNA or cells the way X-rays or gamma radiation do. That distinction matters. The levels where effects start being reported Below ~1 milligauss (0.1 ยตT) This is background level. Youโre in this range most of the day, every day. Think computers at work or home. No documented physiological effects. Between 1โ4 milligauss (0.1โ0.4 ยตT) This is where things get interesting โ not dangerous, but noticeable for some people. People report:โข mild uneaseโข difficulty concentratingโข headachesโข fatigue The World Health Organization notes: โThere is no consistent evidence that low-level EMF exposure causes health effects, although some individuals report non-specific symptoms.โโ WHO, Electromagnetic Fields and Public Health Important translation:People feel things, but itโs not causing physical harm. Around 5โ10 milligauss (0.5โ1.0 ยตT) Now weโre in the zone most often linked to โhauntedโ sensations. This is where lab studies start showing neurological effects, not damage โ but interference. Symptoms reported include:โข dizzinessโข anxiety or dreadโข nauseaโข pressure in the headโข feeling watchedโข emotional shifts The classic reference here is Michael Persinger (Laurentian University), who found that: โComplex partial seizure-like experiences, sensed presences, and emotional disturbances can occur when temporal lobes are exposed to fluctuating electromagnetic fields.โโ Persinger, Perceptual and Motor Skills Journal
