Beijing: Experts warn that if you want to keep your heart healthy and lower your blood pressure, talk less on your phone.
According to a study, talking on a mobile phone for half an hour per week is associated with an increased risk of high blood pressure, and people who spend an hour a day on phone calls are more likely to develop the condition.
A team from the Southern Medical University in Guangzhou, China tried to find out whether there is any relationship between making and receiving calls and the diagnosis of hypertension.
In the research, they reviewed the data of more than 200,000 British citizens and collected information about their mobile phone usage through a questionnaire.
The questionnaire asked the individuals how long they had been using a mobile phone, how many hours per week they used a mobile phone and whether they used a speakerphone or a hands-free device.
In a study that spanned more than 12 years, researchers found that people who talked on the phone for 30 minutes or more each week were less likely to develop high blood pressure. 12 percent were more than those who did.
According to the details, people who spent more than six hours per week on a phone call had a 25 percent higher risk of developing hypertension than those who spent less than five minutes.
However, the length of time study participants had been using a mobile phone or whether they used it hands-free did not appear to have any effect on the risk of hypertension.
