This long-term follow-up recruited participants from an earlier IEI-EMF provocation trial and re-administered the same questionnaire by telephone. Of 70 completers (35 IEI-EMF patients and 35 referents), 62.9% of patients reported recovery after an average of 1.8 years, with most recoveries described as spontaneous.…
Looking for Biomarkers Which May Explain Idiopathic Environmental Intolerance Attributed to EMF (IEI-EMF): Does RF-EMF Exposure Influence Salivary Cortisol Response?

This randomized, double-blind, counterbalanced provocation study tested whether short-term RF-EMF exposure alters salivary cortisol in 72 predominantly young, healthy adults. Active exposure (2 W/kg peak SAR10g in head) showed no significant effect on cortisol compared with sham, and no sex differences were observed.…
Pilot questionnaire survey shows the lack of diagnostic criteria for electromagnetic hypersensitivity: a viewpoint

Jan 1, 2025
This viewpoint reports results from a pilot questionnaire survey of 142 self-declared EHS/IEI-EMF individuals and argues that current evidence and tools do not allow a definitive medical diagnosis of sensitivity to low-level wireless radiation. It notes that many reported diagnoses appear anecdotal and that tests…
Exposure Perception and Symptom Reporting in Idiopathic Environmental Intolerance Attributed to Electromagnetic Fields Using a Co-Designed Provocation Test
Research

Jan 1, 2025
This co-designed provocation study in IEI-EMF volunteers evaluated whether perceived exposure and symptom reporting tracked actual EMF exposure under double-blind conditions. The abstract reports no consistent alignment between perceived exposure certainty or symptoms and true exposure status at the group level, with…
Physiological changes and symptoms associated with short-term exposure to electromagnetic fields: a randomized crossover provocation study.

Jan 1, 2022
This randomized blinded crossover provocation study compared short-term RF-EMF exposure mimicking mobile phone base stations versus sham in people with IEI-EMF and controls. Symptom reporting and physiological measures (blood pressure, heart rate, heart rate variability) were similar between provocation and sham…
Modern health worries and idiopathic environmental intolerance attributed to electromagnetic fields are associated with paranoid ideation.

Jan 1, 2021
This cross-sectional online survey examined whether paranoid ideation is associated with modern health worries and idiopathic environmental intolerance attributed to electromagnetic fields (IEI-EMF). Paranoid ideation was positively associated with modern health worries and with IEI-EMF status, even after controlling…
Association between media coverage and prevalence of idiopathic environmental intolerance attributed to electromagnetic field in Taiwan.

Jan 1, 2018
This ecological study examined whether trends in newspaper coverage about EMF/IEI-EMF in Taiwan were associated with changes in reported IEI-EMF prevalence. The authors report that media coverage rose up to 2007 and then declined through 2012, mirroring a decline in IEI-EMF prevalence between 2007 and 2012. In…
Symptom Presentation in Idiopathic Environmental Intolerance With Attribution to Electromagnetic Fields: Evidence for a Nocebo Effect Based on Data Re-Analyzed From Two Previous Provocation Studies.

Jan 1, 2018
This paper re-analyzes data from two prior double-blind provocation studies involving RF base station signals and sham exposures. Symptoms and reduced well-being were more strongly associated with participants' belief that the base station was "on" than with the exposure condition itself. The authors conclude that a…
Symptom attribution and risk perception in individuals with idiopathic environmental intolerance to electromagnetic fields and in the general population.

Jan 1, 2014
This cross-sectional study compared EMF-related health perceptions and symptom attribution among self-identified EMF-sensitive individuals from an internet panel, non-sensitive individuals, and an NGO-recruited IEI-EMF group. The internet-panel sensitive group reported more non-specific symptoms, higher perceived EMF…
Are media warnings about the adverse health effects of modern life self-fulfilling? An experimental study on idiopathic environmental intolerance attributed to electromagnetic fields (IEI-EMF).

This randomized experiment tested whether a TV report warning about WiFi health effects could influence symptoms during a subsequent sham WiFi exposure. Over half of participants reported symptoms attributed to the sham exposure, and the warning film increased EMF-related worries. Among participants with higher…
