- Scientists have discovered that electro-magnetic
fields emitted by the phones can lead to a rise in blood pressure, reports
the Daily Mail.
-
- The latest research will fuel concern
about the safety of mobile phones, which have already been blamed for causing
brain tumours, headaches and fatigue.
-
- Doctors at the University Neurology Clinic
in Freiburg, Germany, carried out tests by strapping mobile phones to the
heads of ten young volunteers.
-
- They found that blood pressure increased
after 35 minutes of exposure to the mobile phones.
-
- Although the rise was small, doctors
said it could be harmful to people who already suffer from high blood pressure.
-
- Dr Duncan Dymond, consultant cardiologist
at St Bartholomew's Hospital in London, told the Mail: 'A sudden surge
in blood pressure can cause problems, especially for people with coronary
artery disease.'
-
- Alasdair Phillips of Powerwatch, a consumer
service which provides information on electro-magnetic fields, said mobile
phone sellers should be required to put labels on their products warning
against extensive use.
-
- He told the Mail: 'The study could provide
a medical explanation for the three to six-fold increase in headaches reported
among those using their phones for more than an hour a day.
-
- 'Mobile phones should be used for essential
communications only and calls should be kept very short.'
-
- The World Health Organisation has launched
an investigation into whether mobile phones can cause brain tumours.
-
- Recent Swedish research also found a
dramatic increase in headaches and fatigue among people using mobile phones.
-
- The Federation of Communication Services,
which represents mobile phone companies, had no immediate comment on the
latest research.
