STUDIES ON THERAPEUTIC HEATING BY ELECTROMAGNETIC ENERGY
Arthur W. Guy, Justus F. Lehmann, John A. McDougall, Carrol C. Sorenson · 1972
Lower frequency EMF penetrates human tissue more effectively than higher frequencies, creating deeper heating patterns.
Plain English Summary
Researchers studied how electromagnetic energy at different frequencies heats human tissues for medical therapy. They found that lower frequencies (433 MHz) created better, more controlled heating patterns than higher frequencies (2450 MHz). The study used tissue-equivalent models to understand how EMF penetrates and heats different layers of human tissue.
Why This Matters
This 1975 research reveals a fundamental principle that applies far beyond medical therapy: electromagnetic energy interacts differently with human tissue depending on frequency. The finding that 433 MHz penetrates more effectively than 2450 MHz (the frequency used in microwave ovens and WiFi) demonstrates how lower frequencies can have deeper biological effects. While this study focused on intentional heating for therapy, it illuminates how the EMF sources we live with daily create unintended heating patterns in our bodies. The research shows that electromagnetic energy doesn't just bounce off our skin - it penetrates into tissue layers in predictable, measurable ways. What makes this particularly relevant today is that many of our wireless devices operate at frequencies similar to those studied here, creating heating patterns the researchers mapped decades ago.
