The effect of Aires Defender Infinity (i.e. shield), a product that the manufacturer claims protects against harmful electromagnetic radiation, was tested with a healthy 46-year old female who gets headaches when exposed to radio frequency radiation (RFR). She was exposed in a double blind study, to radio frequency radiation (RFR) simultaneously generated by a 2.4 GHz cordless phone base station, Wi-Fi router and wireless baby monitor. Background exposure increased from less than 0.04 mW/m2 to a maximum of approximately 700 mW/m2 . The shield did not change the amount of RFR in the environment; nor did it affect low frequency electric and magnetic fields, dirty electricity or the amount of body current, all of which were low to begin with, however it did alter some physiological responses of subject being tested. Systolic blood pressure decreased slightly with RF exposure but was not altered by the shield.
