This randomized experimental study (N=2,169) tested how different precautionary information formats about RF-EMF (with emphasis on 5G) affect public risk perception and trust in radiation protection authorities in Germany and Greece. Simple precautionary tips generally did not increase risk perception or reduce trust, while a conceptual explanation of the precaution/prevention distinction increased perceived risk compared with simpler information. Precautionary messages improved self-efficacy and perceived message consistency, and responses differed by country and gender.

This cross-sectional questionnaire study (n=100) examined whether electrohypersensitivity (EHS) overlaps with high sensory processing sensitivity (HSPS). A higher proportion of HSPS was observed among those reporting EHS symptoms, alongside significant differences in anxiety/depression symptomatology and EMF-related risk perception and avoidance strategies. The authors interpret the results as supporting an association between EHS and HSPS, while noting that this does not establish whether EM radiation directly causes EHS symptoms.
