View Original AbstractChronic microwave exposure suppressed immune cells by up to 30%, suggesting everyday wireless radiation may weaken your body's infection-fighting ability.
Plain English Summary
Researchers exposed rabbits to microwave radiation at levels similar to some occupational environments (5 mW/cm² at 2.1 GHz) for 3 hours daily over 3 months. They found that microwave exposure significantly suppressed T lymphocytes (immune cells that fight infections) by 21.5% after 2 months and 30.2% during follow-up testing. This suggests that chronic microwave exposure may weaken the immune system's ability to defend against infections and diseases.
Why This Matters
This study provides compelling evidence that chronic microwave exposure can suppress critical immune function, specifically T lymphocytes that serve as your body's frontline defense against infections and cancer. The 5 mW/cm² exposure level used here is well above typical cell phone emissions but within range of some occupational exposures and certain high-power wireless devices. What makes this research particularly significant is the clear dose-response relationship and the persistence of immune suppression even after exposure ended. The science demonstrates that EMF effects on immune function aren't just theoretical concerns but measurable biological changes that could leave you more vulnerable to illness. While this animal study can't directly predict human responses, it adds to a growing body of evidence suggesting our wireless world may be compromising our natural defenses in ways we're only beginning to understand.
Exposure Details
- Power Density
- 5 µW/m²
- Exposure Duration
- 3 h daily, 6 days/week for 3 months
Exposure Context
This study used 5 µW/m² for radio frequency:
- 500Mx above the Building Biology guideline of 0.1 μW/m²
- 8.3Mx above the BioInitiative Report recommendation of 0.0006 μW/cm²
Building Biology guidelines are practitioner-based limits from real-world assessments. BioInitiative Report recommendations are based on peer-reviewed science. Check Your Exposure to compare your own measurements.
