Mobile phone radiation may cause minor brain wave changes but no proven adverse health effects on the nervous system.
Plain English Summary
Summary written for general audiences
This comprehensive review examined how radiofrequency electromagnetic fields from mobile phones affect the human nervous system. While researchers found some minor changes in brain wave patterns (EEG) during GSM phone signal exposure, these changes were not linked to any health problems. Studies consistently showed no significant effects on hearing, balance, or cognitive performance in adults or children.

}Quick Questions About This Study
Yes, some studies found minor changes in spontaneous EEG brain waves during GSM signal exposure. However, these changes were not associated with any adverse health effects or functional problems.
No, studies consistently show that short-term exposure to mobile phone signals does not influence hearing ability or the sense of balance in humans.
No consistent significant effects on cognitive performance have been observed. If anything, studies suggest exposure may slightly improve performance, though effects are small and inconsistent.
No, studies found that effects in children did not differ from those observed in healthy adults. Children showed no greater sensitivity to mobile phone radiation.
While people report these symptoms, controlled provocation studies have never demonstrated a causal relationship between EMF exposure and symptoms. Psychological factors may play an important role.
