He tested the blood pressure of 20 students as they yakked on their mobiles and found that the reading was normal when they were without the phones, but shot up once they started talking on it. In another test 106 students answered questionnaires on their mobiles. 16% had problems with the phones, the researcher said.
"You have to take into account this study was carried out specifically on students but it seems large numbers use mobile phones heavily and this has a significant impact on their lives," Dr Sheffield added.
