The pace of mobile phone technology is advancing at a far quicker pace than the research required into the potential harm they can cause; .... before we can know for certain the effects they have on human health. Nevertheless, mobiles do emit low doses of radiation so common sense dictates precaution should be taken when using them.
Studies have shown that exposure to the RF waves emitted from mobiles can cause: slightly raised blood pressure at the time of use, pressure returning to normal when use is stopped (to put this into perspective, our blood pressure changes regularly throughout the day and is even affected by tasks such as speaking) direct brain warming after prolonged use, which disperses as soon as you stop using your phone and causes no harm mild fatigue after prolonged use a recent study in Sweden suggested that acoustic neuromas (benign tumours of the acoustic nerve) are twice as common in mobile phone users than in those who do not use mobiles.
