According to this research by Dr Havas, some individuals are hypersensitive to microwave radiation and respond when they are exposed to levels well below federal guidelines (5 microW/cm2 or 0.5% of guidelines in Canada & U.S.). During real time monitoring of the heart some individuals experienced an irregular heart rate or a rapid heart rate that occurred only during provocation and not during sham exposure (when the radiation was off). This is the first study showing such dramatic and repeatable results.
The sympathetic nervous system up regulated and the parasympathetic nervous system down regulated during exposure, which is the typical “flight-or-fight” stress response. Feelings of anxiety as well as pain or pressure in the chest were associated with the rapid or irregular heart beat among some of the participants tested.
This test is objective and directly measures the heart’s response to radiation and is unlike subjective testing, where scientists ask individuals if they know whether a device is turned on or off and then determine their “sensitivity” based on perception of exposure, which is just that perception and NOT sensitivity.
It clearly documents that some individuals are hypersensitive to specific frequencies and supports complaints people have when they are exposed to radiation, including a racing or fluttering heart, pain or pressure in the chest, and feelings of anxiety that resemble the onset of a heart attack.
