Cell phone radiation disrupted auditory nerve signals in just 15 minutes, showing the nervous system treats EMF as a biological stressor.

Plain English Summary

Summary written for general audiences

Researchers exposed rabbits to cell phone radiation (GSM-900) and measured how it affected their hearing pathway using auditory brainstem response tests. They found that the radiation caused statistically significant delays in nerve signal transmission through the hearing system, with effects appearing as early as 15 minutes of exposure. The changes returned to normal 24 hours after exposure ended, suggesting the auditory system responds to cell phone radiation as a biological stressor.

Why This Matters

This study provides compelling evidence that cell phone radiation directly affects the nervous system in real-time, specifically disrupting the normal electrical activity of auditory pathways. The fact that measurable changes occurred within just 15 minutes of exposure is particularly significant, as this timeframe represents a typical phone call duration. What makes this research especially relevant is that GSM-900 is the same frequency band used by many cell phones worldwide. The researchers noted that these disruptions follow the pattern of a general stress response, suggesting the nervous system recognizes EMF as a biological stressor. While the effects were reversible in this study, the implications for chronic daily exposure remain concerning, especially given that most people use their phones for far longer than the exposure times tested here.

Exposure Information

Specific exposure levels were not quantified in this study. The study examined exposure from: GSM-900 Duration: 60, 45 and 15 min

Study Details

The objective of the present study was to investigate the possible electrophysiological time-related changes in auditory pathway during mobile phone electromagnetic field exposure.

Thirty healthy rabbits were enrolled in an experimental study of exposure to GSM-900 radiation for 6...

The mean absolute latency of waves III-V showed a statistically significant delay (p < 0.05) after 6...

The prolongation of interval latencies I-V and III-V indicates that exposure to electromagnetic fields emitted by mobile phone can affect the normal electrophysiological activity of the auditory system, and these findings fit the pattern of general responses to a stressor.
