Certain Physiologic and Pathologic Effects of Microwaves
J. F. Herrick, F. H. Krusen · 1953
1953 research documented measurable physiologic and pathologic effects from microwave exposure in humans decades before wireless technology.
Plain English Summary
This 1953 research by J.F. Herrick examined how microwaves affect human physiology and pathology, focusing on tissue heating, blood flow changes, and potential harmful effects. The study represents early scientific investigation into microwave biological effects, decades before widespread consumer microwave technology. This foundational work helped establish our understanding of how electromagnetic radiation interacts with human tissue.
Why This Matters
This 1953 study represents a crucial piece of early EMF research that helped establish the foundation for understanding microwave biological effects. What makes this particularly significant is the timing - this research occurred decades before microwaves became ubiquitous in our homes and workplaces through microwave ovens, WiFi routers, and cell phones. The focus on physiologic and pathologic effects suggests researchers were already observing that microwaves could produce measurable biological changes in human subjects.
The reality is that this early work on tissue heating and blood flow changes anticipated many of the concerns we see today with modern wireless technology. While 1953 microwave exposures were likely much higher intensity than today's consumer devices, the biological mechanisms identified - tissue heating, altered blood flow, and pathological changes - remain relevant to current EMF health discussions. The science demonstrates that biological effects from microwave radiation were documented long before the wireless revolution transformed our daily electromagnetic environment.
Finding
Apparently the temperature of the tissues "triggers" a mechanism which causes an increase in the flow of blood through the tissues. This is an important mechanism for preventing the development of too high temperatures.

Microwaves can heat tissues effectively and maintain temperatures suitable for therapy. Blood flow i...
The primary physiologic effects of microwaves are due to heating. Microwaves are excellent agents for medical therapy due to their ability to produce optimal temperatures and increase blood flow. However, cataracts represent the most serious pathological effect, requiring particular caution in eye exposure. Other undesirable effects include tissue damage in ischemic regions, effusions, and hemorrhage-prone areas. Caution is necessary when treating tissues with compromised circulation or structural vulnerabilities.
