MICROWAVES AFFECT THERMOREGULATORY BEHAVIOR IN RATS
Stern
Microwave radiation at 2450 MHz disrupts rats' natural temperature regulation, revealing biological effects beyond simple tissue heating.
Plain English Summary
This research by Stern examined how microwave radiation at 2450 MHz affects temperature regulation behavior in laboratory rats. The study found that microwave exposure altered how rats naturally respond to temperature changes, suggesting these electromagnetic fields can disrupt biological processes that control body temperature. This matters because it demonstrates microwaves can affect fundamental biological functions beyond just heating tissue.
Why This Matters
This research reveals something crucial that the microwave industry doesn't want you thinking about. When we talk about microwave safety, the focus is always on thermal effects - how much the radiation heats your tissue. But Stern's work shows microwaves can disrupt thermoregulation, the delicate biological process that keeps your body temperature stable, even before significant heating occurs. The 2450 MHz frequency used in this study is the same frequency your microwave oven operates at, and it's close to the frequencies used by WiFi routers and some wireless devices in your home. What this means for you is that microwave radiation can interfere with basic biological functions in ways that current safety standards completely ignore. These standards only protect against tissue heating, not against the disruption of temperature control systems that this research demonstrates.

Study Details
To investigate the effect of microwave exposure on thermoregulatory behavior in rats, specifically examining whether behavioral changes occur at power densities that do not produce measurable colonic temperature changes.

The most parsimonious interpretation of these data is that the rat responds to maintain a constant thermal environment. When heat from one source, microwaves, is introduced, the rat continues to maintain thermal constancy by reducing the heat input from another source, the infrared heat lamp. Although one could propose other mechanisms of microwave action leading to reduced responding, the immediate recovery of responding during the succeeding control periods supports the view that the rat is precisely adjusting its behavior to maintain a nearly constant thermal state. The rat, therefore, can serve as a "thermometer", and thermoregulatory behavior may provide an index of the thermal burden contributed by microwaves. Even if measurable colonic temperature change occurs sometimes at 5 mW/cm2, the observed time course of the behavior change does not parallel it. These behavioral changes, however, were immediately related to the thermal input.
