Modulation of the skin vasoconstrictor tone by 900 Mhz GSM radiofrequency field

Abstract : We hypothesize that the skin vasomotor tone could be modified when the cutaneous blood flow increases under radiofrequency field. The aim of the study was to assess changes of local nervous activity occurring with changes in cutaneous microflow- and temperature- variations of the cheek by laser Doppler flowmetry in young adults during 900 MHz GSM exposure for 20 minutes. The results shown specific athermal effects of RF field upon the increase of skin microflow associated with increases in local sympathetic activity.
