Effets thermiques locaux potentialisés par les ondes radiofréquences

Abstract : In this study, variations in skin micro blood flow and skin temperature were simultaneously recorded in 21 adults with a thermostatic laser Doppler system during radiofrequency (RF) and “sham” mobile phone exposure for 20 minutes. On the control side of the face (non exposed side), the sham and radiofrequency exposure sessions gave rise to similar response profiles for the mean skin blood flow and mean skin temperature values. During radiofrequency exposure, skin blood flow on the exposed side was greater during radiofrequency exposure than during sham exposure. No difference was observed for skin temperature between RF exposed and sham groups. Heating test: the early peak value for skin blood flow (i.e. the raw data after 1 minute of heating at 44 °C) on the exposed side of face was significantly greater after the radiofrequency exposure session than after the sham exposure session. As positive controls, on the contra lateral (non-exposed) side, no difference was found between radiofrequency and sham exposure sessions. These findings show the existence of a vasodilatory effect on skin perfusion of mobile phone radiofrequency emission, which was not due to a temperature difference.
