Plain English Summary
Researchers exposed 26 healthy young adults to radiofrequency signals from a mobile phone while measuring their brain activity using EEG (electroencephalogram). They found that RF exposure significantly reduced alpha brain waves (8-12 Hz), which are associated with relaxed, alert states, and this effect persisted even after the exposure ended. The study carefully controlled for other factors like stress hormones and caffeine that could influence brain activity.
Why This Matters
This research adds important evidence to our understanding of how mobile phone radiation directly affects brain function in real-time. Alpha waves are crucial for cognitive performance, attention, and relaxation - when they're suppressed, it can impact your ability to think clearly and feel calm. What makes this study particularly significant is that the effects persisted after exposure ended, suggesting the brain doesn't immediately return to normal once the RF signal stops. The researchers used rigorous controls to rule out other explanations, strengthening confidence in their findings. While we don't know the exact exposure levels used, this study demonstrates that typical mobile phone emissions can measurably alter your brain's electrical activity patterns.
Exposure Information
Specific exposure levels were not quantified in this study. The study examined exposure from: 8-12 Hz
Study Details
The aim of the present work was to investigate the effects of the radiofrequency (RF) electromagnetic fields (EMFs) on human resting EEG with a control of some parameters that are known to affect alpha band, such as electrode impedance, salivary cortisol, and caffeine.
Eyes-open and eyes-closed resting EEG data were recorded in 26 healthy young subjects under two cond...
Compared with the sham session, the exposure session showed a statistically significant (P < 0.0001)...
These results suggest that GSM-EMFs of a mobile phone affect the alpha band within spectral power of resting human EEG.
