This paper is a commentary reviewing how Bradford Hill’s epidemiological criteria can be applied to multidisciplinary evidence on RF-EMF exposure and adverse health effects. It reports that systematic reviews and meta-analyses in this area often reach substantially different conclusions, and argues that key weaknesses in primary studies—especially exposure measurement error and insufficient time for long-latency tumors—help explain the divergence. The author suggests these limitations may cause underestimation of potential causation if the associations are truly causal, and calls for independent guidelines to improve future epidemiological research quality.
Electrohypersensitivity: what is belief and what is known?

It focuses on distinguishing beliefs about EMF effects from what is currently supported by scientific evidence. The provided text notes ongoing debate and concern and calls for critical assessment of both beliefs and empirical findings.
Exploring the impact of environmental factors on male reproductive health through epigenetics
This narrative review discusses how environmental factors may affect male reproductive health through epigenetic mechanisms, including DNA methylation, histone modifications, chromatin remodeling, and non-coding RNA regulation. It reports that electromagnetic radiation, particularly from mobile phones and wireless devices, is linked in the reviewed literature to reduced sperm count and motility, increased oxidative stress, and chromatin damage. The authors conclude there is a substantive connection between EMF exposure and adverse male reproductive outcomes and suggest practical risk-reduction guidance.
Potential Impacts of Radiofrequency Electromagnetic Fields on the Central Nervous System, Brain Neurotransmitter Dynamics and Reproductive System
This review discusses potential impacts of radiofrequency electromagnetic fields from technologies such as Wi‑Fi and mobile phones on the central nervous system, neurotransmitter dynamics, and reproductive health. It describes proposed mechanisms including oxidative stress, thermal effects, altered neurotransmitter activity, ion channel changes, and neuronal apoptosis, while acknowledging conflicting evidence. The authors note that Wi‑Fi RF exposure has not been confirmed to exceed safety guidelines but argue that updated standards and long-term studies are needed, particularly for children/adolescents and in the context of expanding technologies such as 5G.
An approach for annual analysis of EMF exposure in highly sensitive areas of kindergartens and schools
This paper proposes a time-averaging approach for analyzing long-term EMF exposure using time-series data from three sensors in a regulatory monitoring network. Sensors were installed at two kindergartens and one elementary school, and analyses reported daily/weekly patterns, differences between weekdays and weekends, and site-specific annual increases/decreases. The work emphasizes the value of continuous monitoring in sensitive areas, while not directly assessing health outcomes.
Effects of non-ionizing radiation on the thyroid gland in rats
This animal study exposed Sprague-Dawley rats (including pregnant females and offspring) to 2.45 GHz Wi-Fi or mobile jammer radiation for 2 hours daily over two weeks and assessed thyroid hormones and thyroid histology. The abstract reports significant changes in T4 in exposed adult males and significant differences in T3 among male offspring exposed to jammer radiation. Histopathology reportedly showed disrupted thyroid follicular structure in exposed rats. The authors conclude these findings support a potential link between non-ionizing radiation exposure and altered thyroid endocrine and histological parameters.
A Mini-Review of the Potential Health Impacts of Indoor Radiation Exposure in Companion Animals
This mini-review discusses indoor radiation sources that may affect companion animals, including radon, radionuclides in feed, radiofrequency sources (phones, Wi-Fi, pet tracking devices), solar radiation, and extremely low frequency radiation. It reports that indoor radiation may negatively impact companion animal health and well-being. The authors conclude that preventive and precautionary measures are necessary to protect companion animals from indoor radiation exposure.
Terahertz Radiation Affects the Dynamics of Neurons by Decreasing Membrane Area Ratio
This study reports that terahertz radiation decreased a neuronal membrane area ratio (cytosol relative to protruding membrane area) beginning on the first day of exposure and persisting during the exposure period. It further reports altered neuronal firing/discharge patterns and increased peak postsynaptic currents associated with the morphology change, supported by a kinetic model. The authors frame the findings as indicating significant effects of terahertz-frequency EMF on neural health and function and suggest potential neuromodulation applications.
Exploring the influence of Schumann resonance and electromagnetic fields on bioelectricity and human health
This review examines links between extremely low-frequency electromagnetic fields, especially the Schumann resonance at ~7.83 Hz, and biological regulation of bioelectricity. It describes proposed mechanisms involving calcium flux modulation and downstream effects on neural activity (including EEG) and circadian rhythms. The article presents both potential benefits from controlled ELF exposures (e.g., therapeutic applications) and potential harms from artificial EMFs disrupting key physiological processes, while emphasizing the need for further research.
Effect of short-term extremely low-frequency electromagnetic field on respiratory functions
This animal study tested whether short-term ELF-EMF exposure alters respiratory physiology in rats. Twenty Wistar albino rats were assigned to control or EMF exposure (50 Hz, 0.3 mT for 2 minutes) with respiratory parameters measured before, during, and after exposure. The study reports changes during exposure (lower respiratory rate and higher cycle duration, inspiration time, and tidal volume) but no differences after exposure, and it frames the findings as relevant to EMF safety and potential health risks.
Effects of Mobile Electromagnetic Exposure on Brain Oscillations and Cortical Excitability: Scoping Review
This scoping review evaluates evidence on mobile phone electromagnetic exposure and its effects on brain oscillations and cortical excitability in healthy individuals. Across 78 EEG studies (and 2 TMS studies), the authors report that exposure may be linked to changes in neural activity, including increased amplitudes in several EEG bands and possible changes in cortical silent period. However, substantial methodological inconsistency across studies limits firm conclusions, and the review highlights limited evidence for 5G/mmWave exposures and argues for precaution and potential guideline revision.
Impact of expectancy on fatigue by exposure to the fifth generation of mobile communication signals
This randomized sham-controlled study in 21 healthy participants tested whether routine-level 5G RF-EMF exposure affects fatigue and EEG power, while manipulating expectancy via correct, false, or no information about exposure order. The study reports no change in EEG power with real versus sham exposure. However, self-reported fatigue varied with the conveyed information about being exposed, suggesting an expectancy/psychological priming effect on symptom reporting.
High Radiofrequency Radiation in the Surroundings of 10 Schools in Örebro, Sweden
This exposure assessment measured outdoor RF radiation from 4G/5G base stations near 10 schools in Örebro, Sweden (October 2024). The authors report maximum levels of 10,716–68,452 μW/m² and state these are far above EUROPAEM EMF guideline ranges; two locations also showed higher peak readings with a second meter. The paper frames these findings as indicating a significant health risk, particularly for children and sensitive groups, though no health outcomes were measured in this study.
The effect on rat peripheral nerve morphology and function of a 900-MHz electromagnetic field applied in the prenatal period
This animal study exposed pregnant Sprague Dawley rats to a 900 MHz electromagnetic field for 1 hour daily throughout gestation and assessed offspring outcomes postnatally. Sciatic nerve analyses at postnatal day 60 indicated persistent morphological alterations attributed to prenatal EMF exposure. However, the reported changes were not severe enough to significantly affect measured functional outcomes (including electrophysiology and locomotor tests).
Effects of 700MHz radiofrequency radiation (5G lower band) on the reproductive parameters of female Wistar rats
This animal study examined short- and long-term 700 MHz (lower-band 5G) radiofrequency exposure in female Wistar rats, comparing control, sham, and exposed groups. It reports no DNA damage and no change in estrous cycle length, but increased ovarian oxidative stress markers in exposed animals. Long-term exposure was associated with ovarian histopathological alterations, while estradiol and progesterone stayed within normal ranges and testosterone increased slightly but significantly.
Possible effects of RF EMR on contextual fear conditioning, hippocampal perivascular space, apoptosis and adrenal gland microarchitecture in rats
This animal study exposed male Wistar rats to 900 MHz RF-EMR from a mobile phone for 1 hour daily over four weeks and assessed behavior and tissue changes. The authors report altered contextual fear conditioning-related behavior in exposed rats. Histological assessments indicated apoptosis and enlarged perivascular space in the hippocampal CA3 region and apoptotic/inflammatory-like changes in the adrenal zona fasciculata, with no reported differences in adrenal medulla cytoarchitecture.
Impact of a Terahertz electromagnetic field on the ion permeation of potassium and sodium channels
This biophysics study used molecular dynamics simulations to examine how terahertz electromagnetic fields affect ion permeation in voltage-gated potassium (Kv1.2) and sodium (Nav1.5) channels. The simulations report increased ion permeability at several specific terahertz frequencies, with effects depending on field frequency and direction and increasing with field amplitude. The authors frame these results as evidence of specific EMF–ion channel interactions with potential health relevance and possible biomedical applications.
Effect of electromagnetic field radiation on transcriptomic profile and DNA methylation level in pig conceptuses during the peri-implantation period
This in vitro study exposed pig conceptuses (days 15–16 of pregnancy) to 50 Hz ELF-EMF for 2 hours and assessed transcriptomic and DNA methylation changes. The authors report altered expression of 21 protein-coding transcripts and an approximately 16-fold increase in genomic DNA methylation, with promoter methylation changes in several named genes. They conclude ELF-EMF interacts with gene expression and DNA methylation processes during early development and call for further safety research.
The effects of radiofrequency radiation on male reproductive health and potential mechanisms (Review)
This narrative review summarizes human and animal research on radiofrequency (RF) radiation exposure (e.g., mobile phones, Wi‑Fi, occupational sources) and male reproductive outcomes. It reports that the literature links RF exposure with reduced sperm quality and increased DNA damage, often alongside oxidative stress and other proposed biological changes. Although inconsistencies are acknowledged, the authors conclude the overall evidence suggests harmful associations and call for standardized, long-term studies and reconsideration of guidelines.

Repeated Head Exposures to a 5G-3.5 GHz Signal Do Not Alter Behavior but Modify Intracortical Gene Expression in Adult Male Mice
This animal study examined repeated asymmetrical head exposure to a 5G-modulated 3.5 GHz signal in adult male mice for six weeks. It reports no significant changes in locomotion, anxiety, or object-based memory performance under the tested conditions. However, it found statistically significant but limited cortical gene expression changes (<1% of expressed genes), including enrichment for glutamatergic synapse-related genes and lateralized differences involving mitochondrial genome-encoded genes. The authors caution that potential health risks from these intracortical transcriptomic modifications should not be downplayed and note uncertainties about longer exposures and other populations.
The CB1R of mPFC is involved in anxiety-like behavior induced by 0.8/2.65 GHz dual-frequency electromagnetic radiation
This animal study reports that dual-frequency RF EMR exposure (0.8/2.65 GHz, 4 W/kg) induced anxiety-like behavior in mice. It also reports reduced CB1R and endocannabinoid levels in the mPFC and altered endocannabinoid system markers in the BLA. CB1R overexpression or knockdown in the mPFC reportedly decreased or increased anxiety-like behavior, respectively, suggesting a mechanistic link in this model.
Enhancement Effect of Static Magnetic Field on Bactericidal Activity
This in vitro study reports that a static magnetic field (SMF) combined with paramagnetic calcium-polypyrrole nanoparticles (Ca-PPy) markedly increases bactericidal activity against E. coli and S. aureus. The authors attribute the enhanced killing to increased reactive oxygen species generation and associated membrane disruption, with computational analysis suggesting altered radical-pair transitions under magnetic fields. The abstract frames SMF as potentially biocompatible and useful for bactericidal applications, while also noting broader biological impacts of electromagnetic fields.
