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 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 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 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…
