LONDON, ENGLAND -- June 19, 1998 -- Radio-frequency electromagnetic fields emitted by mobile telephones cause an increase in blood pressure, report Dr. S. Braune and colleagues from Freiburg, Germany, in this week's issue of The Lancet. The 10 volunteers studied were all young (26-36 years) and each had a mobile telephone attached to the right-hand side of their heads where a telephone would usually be held. The phones were switched on by remote control at various intervals, but without sound, so that the volunteers did not know when they were being exposed to the electromagnetic fields. The researchers then measured blood pressure while the volunteers were lying down and standing up, along with other measurements of heart function. Dr. Braune and colleagues recorded increases of five to 10 mmHg in blood pressure while the volunteers were resting and exposed to the switched-on mobile telephone. Such an increase could have adverse effects on people with high blood pressure. They conclude that the increase in blood pressure probably resulted from constriction of the arteries caused by the radio-frequency electromagnetic field. The researchers did not, however, examine the possible effect on those in the vicinity of mobile-phone users. --------------------------------------------------------------------------------------------- Copyright © 1999 P\S\L Consulting Group Inc.
