Effects of mobile phone use on superficial cutaneous and internal cerebral circulation (PHYSIOREF project). Part I : Laser-Doppler recording of microflow - and temperature - modifications of head's skin

Abstract : Heating caused by mobile phone exposure could modify cutaneous thermoregulation. The aim of the study was to quantify, simultaneously and at the same site, cutaneous microflow- and temperature- variations of the cheek by laser Doppler flowmetry in young adults during 900 MHz GSM exposure of 20 minutes. The preliminary results obtained in 8 subjects shown a significant and gradual increase in skin microflow associated with proportional increase in local skin temperature under mobile phone exposure.
