Feb 17, 2026
This animal experiment exposed rats to 6 GHz RF-EMR from a signal generator for 4 hours/day over 6 weeks and assessed plasma oxidative stress markers and kidney histology. The RF-EMR group showed lower plasma GSH, CAT, SOD, and MDA levels than control and sham groups, while cortisol did not differ. The authors also…

This triple-blind randomized study tested whether 26.5 minutes of 26 GHz (5G) RF exposure at environmental-like levels alters salivary stress biomarkers in healthy adults. Salivary cortisol and alpha-amylase measured before, during, and after exposure did not differ between real and sham conditions. An exploratory…
Looking for Biomarkers Which May Explain Idiopathic Environmental Intolerance Attributed to EMF (IEI-EMF): Does RF-EMF Exposure Influence Salivary Cortisol Response?

Jan 1, 2025
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.…
What is the effect of alarmist media and radiofrequency electromagnetic field (RF-EMF) exposure on salivary cortisol and non-specific symptoms?

Jan 1, 2025
This randomized study tested whether viewing alarmist media and participating in an open-label RF-EMF provocation trial influenced non-specific symptoms and salivary cortisol. Participants who believed they were being exposed reported more symptoms than those who believed they were not exposed. The study did not find…

This animal experiment assessed visual memory, cortisol, GR gene expression, and amygdala volume in four male rhesus macaques exposed to a 12 Hz, 0.7 μT ELF magnetic field. The exposed monkeys reportedly showed improved visual memory and reduced serum cortisol and GR gene expression, while controls did not show…
Effect of short exposure to radiofrequency electromagnetic fields on saliva biomarkers: a study on the electrohypersensitive individuals.

Jan 1, 2019
This double-blind provocation study examined whether short RF-EMF exposure alters salivary biomarkers in electrohypersensitive (EHS) individuals. Ten participants underwent sham and real exposure sessions with consecutive GSM 900, GSM 1800, DECT, and Wi‑Fi signals for 5 minutes each. The study reports no significant…
