Plain English Summary
Researchers exposed 36 volunteers to electromagnetic fields from both a medical therapy device and a mobile phone, then measured their brain activity using EEG recordings. Both EMF sources caused measurable changes in brain wave patterns, with the therapy device affecting brain activity immediately and the mobile phone causing delayed effects about 15 minutes after exposure. This demonstrates that electromagnetic fields can directly alter human brain function in ways that persist even after the exposure ends.
Why This Matters
This 1995 study provides early evidence that EMF exposure can measurably alter human brain activity patterns. What makes this research particularly significant is that it used proper scientific controls and found consistent effects from two different EMF sources. The delayed response to mobile phone exposure is especially noteworthy, suggesting that EMF effects on the brain don't just occur during exposure but can persist and even emerge after the field is turned off. While the study doesn't specify exact exposure levels, the fact that both a medical device and an early digital mobile phone produced similar brain wave changes indicates this is a reproducible biological response. The reality is that if EMF can alter brain activity patterns in controlled laboratory conditions, we should take seriously the possibility that our daily EMF exposures from phones, WiFi, and other wireless devices may be affecting our neurological function in ways we're only beginning to understand.
