Dr. Paolo Paredi of the National Heart & Lung Institute, London, United Kingdom said that his research followed increasing speculation about the potential influences of radio-frequency electromagnetic fields on human well being. "The use of...mobile telephones has been associated with headaches, increased blood pressure, and brain damage," he said. "Furthermore, people exposed to very low intensity microwave energy, like that emitted by mobile phones, report hearing sounds like buzzes, clicks and tones, there are also reports of headaches, sensation of burning skin, fatigue and hot ears," he added. The possibility that some of the biological actions of mobile phones may be due to an increase in tissue temperature led Paredi and colleague Professor Peter Barnes to measure the facial skin temperature of 30 subjects during a thirty minute mobile phone conversation using a commercially available cellular mobile phone."We found a significant increase in temperature after just two minutes of telephone conversation with a maximal increase of 2.3 degrees centigrade after six minutes," he reports. "The temperature returned to baseline levels within three minutes after the end of the telephone conversation. The changes in skin temperature were reproducible and were present in all the subjects studied," according to Paredi."Interestingly, such changes were not recorded when an earpiece was used to avoid direct exposure to the electromagnetic field," he said. Paredi also found that nasal resistance increased in the nostril on the same side as the telephone. "We assume this is due to the dilation of the arteries and veins in the nose caused by the temperature increase," he said. "This hypothesis was confirmed by a moderate increase in the levels of nasal nitric oxide, a gas that causes smooth muscle relaxation and vasodilation," he continued. "The increased nasal resistance may account for the sensation of closed nose that most of the volunteers experienced during the telephone conversation." Paredi and colleagues call for additional studies to examine long-term effects of mobile phone use.
