Effects of exposure to nearby mobile phone base stations and mobile phone usage on human blood parameters

​ Laldinpuii et al. · 2026

Researchers compared 50 people highly exposed to mobile phone base stations with 51 reference individuals, measuring complete blood counts and the stress markers amylase and cortisol. Stepwise regression showed that base-station exposure significantly predicted total leukocyte count, while gender, age and power density predicted basophil and monocyte counts, and daily mobile-phone use with age predicted basophil and lymphocyte counts. Almost a quarter of the highly base-station-exposed group had basophil counts above reference limits, and over half of heavy mobile-phone users (4–6 hours daily) had lymphocyte counts above limits, most under 30 years old. Smoking and age influenced amylase, but no exposure variable affected amylase or cortisol.

RF-EMF Risk Perception and Trust in Radiation Protection Authorities: A Comparative Study on Precautionary Information in Germany and Greece

Eggeling-Böcker M et al. · 2026

Researchers randomly assigned 2169 participants to basic, simple precautionary, or conceptual precautionary information about reducing RF-EMF exposure from mobile phones. Simple precautionary messages increased general conditional risk perception only when participants assumed no precautions were taken, but did not affect affective risk perception, trust, or risk perception when precautions were assumed. Providing an elaborate explanation of the precaution-prevention distinction did not reduce risk perception or increase trust compared to simple precautionary information, and increased risk perception compared to basic information. Greek participants reported higher perceived risks and lower trust than German participants, and women expressed higher risk perception and less trust than men.

Review of the evidence on the influence of Wi-Fi 2.4 GHz radiation on oxidative stress and its possible relationship with Alzheimer’s disease

Laván D et al. · 2025

The researchers indirectly analyzed the relationship between oxidative-stress-responsive genes after Wi-Fi 2.4 GHz exposure and genes linked to Alzheimer’s disease. They reported that prolonged exposure to this radiation could worsen the modification of key neurodegeneration genes such as GSK3B and APOE. The authors note that the link between wireless systems and Alzheimer’s disease remains inconclusive and requires further research.

Greater prevalence of symptoms associated with higher exposures to mobile phone base stations in a hilly, densely populated city in Mizoram, India

Sailo L et al. · 2025

Researchers gave a symptom questionnaire to 183 highly exposed and 126 reference residents matched on demographics in a hilly city in Mizoram, India. They measured RF-EMF levels in residents' lounge rooms and compared symptoms between those living closer than 300 meters and farther than 400 meters from base stations. Residents living closer reported more symptoms in all four health categories, and higher exposure levels were the only factor predicting the number of symptoms.

Intercomparisons of computed epithelial/absorbed power density and temperature rise in anatomical human face models under localized exposures at 10 GHz and 30 GHz

Li K et al. · 2025

Two high-resolution anatomical face models extracted from whole-body models were used at 10 GHz and 30 GHz. The results suggest that when appropriate averaging methods are applied, spatially averaged APD and temperature rise in realistic human face models are statistically correlated.

Prevalence of self-reported sensitivities to various environmental factors in Germany, Sweden, and Finland based on multiple classification criteria

Köteles F, Witthöft M, Bräscher AK, Bailer J, Nordin S · 2025

Researchers used population-based survey data from Germany (n=2515), Sweden (n=3253), and Finland (n=1467) to report prevalence rates of five environmental sensitivities and compare three of them across countries. In the German sample, about 25% of participants reported mild reactions to sounds, chemicals, and buildings, and about 10% to electromagnetic fields (EMFs) and wind turbines, with strong reactions at 1-2%. Data from Sweden and Finland showed consistent similarities, with prevalences exceeding 34% for mild reactions to chemicals and sounds and about 5% to EMFs, with strong reactions at 1-8%.

(2025) Radiofrequency radiation from mobile phones and the risk of breast cancer: A multicenter case–control study with an additional suspected comparison group

Tahmasebi et al · 2025

This multicenter case–control study recruited 226 women in Iran classified as controls, suspected cases, and confirmed breast cancer cases. Structured questionnaires collected data on mobile phone call duration, screen time, and phone placement. Longer screen time (>4 h/day), later age at menarche, lower education level, and exposure to environmental pollutants were also associated with increased odds.

Analyzing the impact of occupational exposures on male fertility indicators: A machine learning approach

Unknown authors · 2025

Researchers collected data from 80 male workers in an automobile part manufacturing plant, including demographic characteristics, occupational exposures, biochemical markers, hormone levels, and sperm parameters. They trained five machine learning models using 5-fold cross-validation to predict reproductive health outcomes. Exposure to whole-body vibration, magnetic fields, electric fields, and heat stress closely affected free testosterone levels. The XGBoost and random forest models achieved the highest AUC of 0.99. Random Forest importance indicated electric field exposure (5%) and magnetic field exposure (4.7%) had the most substantial negative impact on free testosterone.

A Cohort Study on Alzheimer's Disease in Relation to Residential Magnetic Fields From Indoor Transformer Stations

Unknown authors · 2025

Researchers studied 155,562 individuals living in buildings with indoor transformer stations, comparing 5,652 residents in apartments next to the transformer room (exposed) with 115,772 residents on higher floors (referents). Alzheimer's disease cases were identified from the Drug Purchase Register and the Drug Reimbursement Register, and associations were analyzed with Cox proportional hazard models. The overall hazard ratio for Alzheimer's disease was 1.02 (95% CI 0.85–1.22), showing no increased risk, and the hazard ratio for those who began residence before age 50 was 1.22 (95% CI 0.94–1.57), which was not statistically significant.

Intermittent ELF-MF exposure effectively ameliorates pathologic features associated with adult AD mice

Geng D, Liu A, Yan Y, Zheng W · 2025

ELF-MF stimulation improved spatial working memory in the AD model mice. Local field potential analysis showed that AD reduced theta and gamma band energy in the hippocampal CA1 region, while ELF-MF stimulation significantly enhanced this energy. Immunofluorescence detection revealed that ELF-MF stimulation reduced abnormal accumulation of Aβ42 and Drp1 in the hippocampus, with intermittent stimulation showing a more significant effect in adult mice.

Effects of moderate static magnetic fields on voltage-gated potassium ion channels in sympathetic neuron-like PC12 cells

Kaneda E, Kawai T, Okamura Y, Miyagawa S · 2025

Researchers investigated the effects of moderate static magnetic fields on Kv channels in sympathetic neuron-like PC12 cells. After 18 hours of exposure, Kv channel current density was significantly lower in the exposed group, and the effect persisted after magnet removal. RNA sequencing identified 37 SMF-sensitive genes, and gene expression changes suggested pathways inhibiting neuronal excitability may be more likely activated.

The association of widely used electromagnetic waves exposure and pregnancy and birth outcomes in Yazd women: a cohort study

Unknown authors · 2025

The study enrolled 1,666 women in the Yazd Mother and Child Cohort between 2015 and 2019 and examined exposure to cell phones, cordless phones, and Wi-Fi. Outcomes included miscarriage, preterm labor, abnormal birth weight, and deviations in newborn height and head circumference. Longer cell phone call duration was associated with higher risks of miscarriage, abnormal birth weight, and height, while cordless phone conversations could increase the risk of abnormal weight in newborns.

Men with genetic predisposition face greater fertility challenges when exposed to electromagnetic radiation

Pal S, Paladhi P, Dutta S, Ghosh P, Chattopadhyay R, Ghosh S · 2025

Researchers genotyped 708 azoospermic men and 640 healthy controls for variants in SPO11, RNF212, and SYCP3 using Sanger sequencing. Binary logistic regression assessed the interaction between genetic variants, electronic radiation exposure, and age on fertility status. The analysis found a significant association between these genetic variations and increased azoospermia risk, particularly in men aged 30 or older exposed to electronic radiation.

Does Electromagnetic Pollution in the ART Laboratory Affect Sperm Quality? A Cross-Sectional Observational Study

Unknown authors · 2025

Researchers conducted a cross-sectional observational study with 102 healthy males aged 20–35 years in an IVF laboratory. Semen samples were exposed to different EMF sources for one hour and motility was assessed immediately. Progressive sperm motility decreased significantly after exposure to mobile phone and Wi-Fi repeater EMFs, but other equipment had no significant effect.

The Effect of 5G Mobile Phone Electromagnetic Exposure on Corticospinal and Intracortical Excitability in Healthy Adults: A Randomized Controlled Pilot Study

Unknown authors · 2025

Nineteen healthy participants with a mean age of 36.5 years were exposed to 5G mobile phone exposure at 3.6 GHz and 0.0030 W/m2 for 5 and 20 minutes. Corticospinal excitability, intracortical facilitation, short intracortical inhibition, and long intracortical inhibition were measured with transcranial magnetic stimulation before and after exposure. A repeated-measures ANOVA found no significant interactions between exposure condition and time for any of these measures (all p > 0.15). Bayesian analyses gave Bayes factors close to 1, indicating inconclusive evidence for both the null and alternative hypotheses.

The Influence of Mobile Technologies on the Quality of Sleep

Unknown authors · 2025

Researchers explored the influence of mobile phone-emitted RF-EMFs on sleep duration and quality in a cohort of medical students. Participants alternated between sleeping with and without a mobile phone for two-week intervals while sleep patterns were monitored using smartwatches. The study found no statistically significant disparities in sleep quality between sleeping with and without a mobile phone. However, RF-EMF exposure had a notable impact on minimum and average blood oxygen saturation levels.

Effects of Radiofrequency Electromagnetic Fields on Cognitive Function in Elderly Subjects (60+ years) - Results of an Experimental Randomized Sham Controlled Double- Blind Cross- Over Study in Women and in Men

Sauter C et al. · 2025

Sixty healthy women and men aged 60 to 80 years completed four attentional tasks in nine sessions while exposed to GSM 900 MHz, TETRA 385 MHz, or sham exposure. Two of 16 performance measures were significantly affected by exposure in women only, with worse accuracy in an n-back task under GSM exposure in the easier version and under TETRA exposure in the highest level. Performance of women and men did not differ significantly overall, and only one significant sex-exposure interaction was observed under TETRA exposure, indicating better performance in men and worse in women compared to sham. The researchers concluded that overall cognitive performance of healthy elderly participants was not affected by short-term RF-EMF exposure.

Radiofrequency evoked potentials: A new window into the nociceptive system

Unknown authors · 2025

Seventeen healthy volunteers received radiofrequency and electrical stimulation on the hands and feet while EEG was recorded. Radiofrequency stimulation was capable of selective activation of nociceptive fibres through rapid skin heating. Radiofrequency evoked potentials showed the highest degree of synchronicity achieved to date for cortical responses to thermal stimulation. The N2 and P2 peak latencies were longer for radiofrequency evoked potentials than for electrical stimulation evoked potentials. The P2 peak latency was also longer for foot stimulation than for hand stimulation.

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

Michelant L et al. · 2025

Researchers conducted a randomized, triple-blind crossover study in 31 healthy young adults. Participants received a 26.5-minute exposure to 26 GHz electromagnetic fields at 2 V/m in real and sham sessions separated by one week. No significant modulation of EEG frequency bands was observed during eyes-closed conditions following 26 GHz exposure.

Modulation of brain functional connectivity in healthy young adults following GSM radiofrequency exposure: A magnetoencephalography and magnetic resonance imaging study

Iranfar S, Wallace J, Selmaoui B, Yahia-Cherif L · 2025

The study aimed to test whether GSM radiofrequency exposure modulates brain functional connectivity. Healthy young adults were exposed to GSM signals at 900 MHz, modulated at 217 Hz with a maximum power of 2 W. Real exposure produced significant alterations in intra-hemispheric functional connectivity, especially in right-hemisphere regions such as the transverse temporal, entorhinal, insula, and posterior cingulate.

Analysis of the Association of Mobile Phone Usage and Hearing Function in Young Adults

Unknown authors · 2025

Seventy-eight young adults aged 17 to 24 years were recruited, completed a validated questionnaire on phone usage, were grouped by duration of use, and underwent pure tone audiometry. Mild to moderate hearing loss was evident in all three usage groups at 250 Hz, 500 Hz, and 1000 Hz. Hearing loss was more evident in individuals who used phones for more than 30 minutes per day for five years continuously compared to those with shorter use. Significant hearing loss was found in 4G phone users compared to 5G users at 250 Hz and 500 Hz but not at frequencies between 1000 Hz and 8000 Hz, particularly in the left ear. Ear dominance did not play a significant role in influencing hearing loss.

Effects of Extremely Low-Frequency Electromagnetic Field Treatment on ASD Symptoms in Children: A Pilot Study

Unknown authors · 2024

The study enrolled 20 children aged 2 to 13 with a confirmed ASD diagnosis. They received ELF-EMF treatments using the SEQEX device over a 15-week protocol with day and night programs. Receptive language scores on the PPVT-4 improved from 74.07 to 90.40 (p=0.002) and expressive language scores on the EOWPVT-4 improved from 84.17 to 90.50 (p=0.041). Externalizing problems decreased significantly in both the 1.5–5 year group (p=0.028) and the 6–18 year group (p=0.027).
