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…

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…

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…

This magazine article discusses the rising incidence of thyroid cancer and raises the possibility of an association with increased smartphone use and related RF EMF exposure near the head and neck. It characterizes EMF exposure from personal electronics as a growing public health concern. The piece calls for more…

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…

This cross-sectional study surveyed 2,317 college students to examine associations between smartphone addiction and sleep quality. Smartphone addiction was associated with poorer sleep quality, and mediation analyses indicated that higher perceived stress and lower health-promoting lifestyle scores partially…

This secondary analysis of a nationally representative Korean adolescent survey examined bidirectional associations between smartphone overdependence and anxiety. In adjusted models, high risk for smartphone overdependence was associated with higher odds of anxiety, and severe anxiety was associated with higher odds…

This 30-day daily diary study of 104 first-year undergraduates in China examined links between problematic smartphone use (PSU) and disengagement at within- and between-person levels. The analyses reported bidirectional next-day associations, where higher-than-usual PSU predicted higher-than-usual disengagement and…

This engineering/simulation study evaluates tissue SAR from a smartphone operating under single-frequency versus combined (simultaneous 4G and 5G) RF exposure scenarios using multi-pose human models. It reports that peak SAR in various tissues under multi-frequency exposure was 1.02 to 15.85 times higher than under…

RF Safe argues that red blood cell (RBC) “rouleaux” (stacking/aggregation) could be a visible, testable endpoint for investigating potential short-term physiological effects from wireless device exposure. The post highlights a 2025 report by Brown & Biebrich describing ultrasound observations interpreted as…

RF Safe founder John Coates outlines a 2026 advocacy plan focused on increasing enforcement of U.S. federal radiation-control law, pushing consumer technology toward Li‑Fi as a safer baseline for children, and demanding accountability from companies marketing wireless products to children. The post argues that…

An RF Safe commentary argues that persistent, pulsed “non-native” RF electromagnetic noise can disrupt biological “timing coherence,” leading to downstream “fidelity losses,” particularly in electrically active tissues. It also emphasizes that smartphones are adaptive RF systems that change transmit power and…

This RF Safe commentary argues that non-thermal RF/5G effects may vary by tissue based on the density of specific biological “targets,” such as voltage-gated channel S4 helices, mitochondrial/NOX ROS capacity, and heme/flavin “spin chemistry” substrates. It claims that reported null findings in 5G mmWave skin-cell…

RF Safe comments on a 2025 PNAS Nexus study (Jyoti et al., 2025) reporting no detectable changes in gene expression or methylation in 5G millimeter-wave–exposed human skin cells. The post argues that this “null” result does not indicate biological inertness, but instead supports the site’s proposed “dual-pillar”…

This retrospective observational study analyzed Murmuras app data from 1074 participants in 2022 to examine demographic differences in smartphone use and nocturnal smartphone inactivity duration (a proxy for sleep-related behavior). Nighttime smartphone use increased, especially for social media and entertainment,…

This study tested magnetic fields from tablets, laptops, smartphones, and household/leisure magnets against 13 cardiac implantable electronic device (CIED) models to assess magnet mode activation. It reports that these consumer devices can trigger magnet mode when in close proximity, with median activation distances…

This study compared 42 college students grouped by high versus low screen time during a 2-back working memory task while measuring brain activity with fNIRS. The low screen time group performed better on working memory accuracy/hit rate, while reaction time and false alarms did not differ. Neuroimaging results…

This systematic review and meta-analysis synthesized observational MRI studies comparing excessive smartphone users with regular users. It reports smaller brain volumes in excessive smartphone users, especially in subcortical regions, and notes that the association was more pronounced in adolescents than adults. It…

This animal study examined whether exposing Dermacentor reticulatus tick eggs to 900 MHz RF-EMF for 30, 60, or 90 minutes affects the size of hatched larvae. The authors report that the 60-minute exposure group produced larvae with larger measurements across four body traits compared with unexposed controls and other…
