Non‑Thermal EMF Harm Signals (Moderate Evidence): Reproductive DNA Damage, Pregnancy Risk, Tumor Relevance, and Ecological Disruption

Research Effect Synthesis Mar 1, 2026

Synthesis of 13 moderate-evidence harm papers: 5G-band RF increased sperm DNA fragmentation in vitro; pregnancy cohort linked call time to miscarriage and growth outcomes; lifetime RFR tumor genetics support translati…

2026 Evidence Snapshot: Non‑Thermal RF Bioeffects Across 6 GHz, 3.5 GHz, 2.45 GHz, and 28 GHz—Why Heat‑Only Safety Limits Don’t Track Biology

Research Effect Synthesis Mar 1, 2026

Synthesis of 13 studies (2026) spanning 6 GHz, 3.5 GHz, 2.45 GHz Wi‑Fi, 28 GHz mmWave, and real‑world base‑station proximity and smartphone use. Across mechanistic, animal, and observational evidence, multiple biologi…

2026 EMF Research Snapshot: Non‑Thermal Biological Effects Across 6 GHz, 3.5 GHz, 2.45 GHz Wi‑Fi, and 28 GHz mmWave—Why Thermal‑Only Safety Limits Are Not Enough

Research Effect Synthesis Mar 1, 2026

Synthesis of 12 studies (2026) linking RF/EMF exposures and wireless tech use to oxidative stress, apoptosis, reproductive harm, kidney changes, sleep disruption, and base-station symptom patterns—supporting precautio…

Evening smartphone exposure impairs sleep quality and next-day performance in elite soccer players: a randomized controlled trial.

Research RF Safe Research Library Jan 1, 2026

This randomized controlled crossover trial in 16 male elite soccer players compared two hours of smartphone use before bedtime with magazine reading. Five consecutive nights of pre-bedtime smartphone use significantly worsened multiple sleep metrics and increased sleepiness. The study also reports deteriorations in…

Millimeter-wave high frequency 5G (26 GHz) electromagnetic fields do not modulate human brain electrical activity

Research RF Safe Research Library Jan 1, 2025

This randomized, triple-blind crossover study examined whether 26 GHz (5G millimeter-wave) exposure affects human EEG activity. Thirty-one healthy young adults completed real and sham 26.5-minute exposures at 2 V/m, with EEG recorded before, during, and after exposure. The study reports no significant effects of…

The Effect of Extremely Low-Frequency Electromagnetic Fields on Inflammation and Performance-Related Indices in Trained Athletes: A Double-Blinded Crossover Study.

Research RF Safe Research Library Jan 1, 2023

This double-blinded crossover study tested an ELF-EMF mattress used immediately after high-intensity cycling and overnight in nine trained male athletes. The authors report no significant overall effects on performance and inflammation. However, between 60 minutes and 24 hours post-exercise, the active condition…

Physiological changes and symptoms associated with short-term exposure to electromagnetic fields: a randomized crossover provocation study.

Research RF Safe Research Library 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…

Efficacy of extremely low-frequency magnetic field in fibromyalgia pain: A pilot study.

Research RF Safe Research Library Jan 1, 2016

This pilot randomized study evaluated systemic extremely low-frequency magnetic field (ELF-MF) therapy versus sham in 37 women with fibromyalgia using a crossover sequence. The abstract reports significant short-term reductions in pain and improvements in fibromyalgia-related symptom and function questionnaires…

The alteration of spontaneous low frequency oscillations caused by acute electromagnetic fields exposure.

Research RF Safe Research Library Jan 1, 2014

This double-blind, randomized, crossover study examined whether 30 minutes of near-field LTE radiofrequency exposure near the right ear alters resting-state brain activity measured by fMRI. The authors report decreased ALFF in multiple temporal and frontal/paracentral regions after real exposure compared with sham,…

Whole brain EEG synchronization likelihood modulated by long term evolution electromagnetic fields exposure.

Research RF Safe Research Library Jan 1, 2014

This conference paper examined whether LTE radiofrequency EMF exposure affects whole-brain EEG functional connectivity. Ten participants completed a crossover, double-blind real versus sham exposure protocol with 30 minutes of exposure per session while 32-channel EEG was recorded. Using synchronization likelihood,…

Sham Transcranial Magnetic Stimulation Using Electrical Stimulation of the Scalp.

Research RF Safe Research Library Jan 1, 2009

This study describes development and validation of a sham rTMS approach that combines a matched sham coil (for look/sound) with scalp electrical stimulation (for sensation). In back-to-back comparisons, TMS-naïve participants reportedly could not tell active from sham, whereas experienced participants could. The…
