Abstract

Recent studies have revealed that rodents’ physiological responses to low intensity radiofrequency electromagnetic fields (RF) were similar to thermoregulatory responses to cold conditions. We investigated the effects of 900 MHz RF at a low level (0.35 W.kg-1) on tail skin temperature (Ttail) in rats at ambient temperature (Ta) between 24 and 34°C. We showed that rats exposed to RF had lower Ttail than control rats at Ta between 27 and 31 °C. This difference in Ttail was suppressed after the injection of a vasodilator, confirming the vasoconstriction in exposed rats. Moreover, like a response to cold stimuli, RF exposure led to a higher plasma concentration of factors involved in response to cold: noradrenaline and fatty acids.
