An Important Research about MobilePhones.
Talking on a mobile phone causes systolic blood pressure, the higher
number in a blood pressure reading and the number doctors pay more
attention to as a risk factor for cardiovascular disease, to rise
significantly, a study has found. Researchers from the Guglielmo da
Saliceto Hospital in Piacenza, Italy, took 12 blood pressure readings
at one-minute intervals from 94 patients with mild hypertension. The
patients' mean age was 53, Khaleej Times reported. Patients were seated
in a comfortable armchair in a doctor's consulting room and left alone
after the first blood pressure reading was taking using an automatic
device. Researchers phoned the patients at least three times and found
that when the patient as on the phone or receiving a call, their blood
pressure reading jumped from 121/77 on average to 129/82. The American
Heart Association say less than 120/80 is a healthy reading for adults
age 20 and older. During the blood pressure study, neither diastolic
blood pressure - the lower number in a blood pressure reading, which is
a measure of the force of blood in the arteries when the heart relaxes
between beats-nor heart rate increased significantly when patients
received a call. Oddly,
though, the researchers found that patients who got more than 30 calls a
day seemed to have developed a form of immunity to the blood pressure
spikes seen in the study. Beta blockers also seemed to help stave off
blood pressure spikes. The researcher concluded that phone calls
received when a midlly hypertensive patient is having a blood pressure
reading could cause syslotic pressure to spike, and advised that they
turn off their phone, at least for a duration of blood pressure test.
