1934 study of 2,000 people proved radio waves cause immediate nervous system effects at power levels below modern devices.

Plain English Summary

Summary written for general audiences

This 1934 German study exposed 2,000 people to radio frequency fields at 0.1 watts and documented immediate nervous system effects including tingling sensations, blood vessel changes, and altered brain function. The researchers found that RF exposure caused measurable changes in body electrical resistance and disrupted normal balance reactions when specific brain regions were targeted.

Why This Matters

What makes this 1934 research remarkable is not just its early date, but its massive scale and systematic documentation of RF bioeffects that mirror complaints we hear today from people experiencing electromagnetic hypersensitivity. The science demonstrates that radio waves were causing measurable nervous system responses in humans nearly a century ago, long before our current wireless saturation. The study's finding that sensitive individuals showed more pronounced reactions aligns with modern research on individual susceptibility to EMF exposure. What this means for you is that biological responses to radio frequencies aren't new phenomena, and the intensity levels used in this study (0.1 watts) are actually lower than many of today's wireless devices that operate at several watts of power.

Exposure Information

Specific exposure levels were not quantified in this study.

Quick Questions About This Study

The researchers used 0.1 watts as their field intensity limit and observed immediate nervous system responses including tingling sensations, blood vessel changes, and altered brain function in their 2,000 test subjects.
The German researchers tested 2,000 human subjects using radio frequency fields, making this one of the largest early studies documenting biological effects of electromagnetic radiation on the human nervous system.
Yes, the study found that radio frequency irradiation changed the body's high-frequency electrical resistance by 6 to 10 percent, with resistance returning to normal levels after exposure ended.
When researchers directed radio waves at specific brain regions, they disrupted normal balance and spatial orientation reactions, causing what they termed 'pathological' responses in standard neurological tests with closed eyes.
The researchers noted that subjects being treated for nervous disorders showed 'marked distinctness' in their responses to radio frequency exposure, suggesting increased sensitivity in neurologically vulnerable individuals.
