From an absence of train to poor dietary selections, there are some apparent triggers for high blood pressure, often known as hypertension.

However, a new study, revealed within the European Heart Journal, has prompt that your telephone may additionally pose a danger.

While social media and varied messaging companies have made calls much less well-liked, simply half-hour every week spent chatting in your cellular may elevate your blood stress danger, the analysis suggests.

Worryingly, hypertension is a stepping stone to severe health issues, starting from heart attacks to strokes.

Whether you decide up the telephone to telephone a good friend or to do some admin, the researchers are recommending maintaining your chats to a minimal.

The findings prompt that those that spent simply half an hour on the telephone talking, even hands-free, had been 12 % extra susceptible to high blood pressure.

Furthermore, six hours of telephone chats every week raised the chance to 25 %.

Lead writer Professor Xianhui Qin, of Southern Medical University, Guangzhou, mentioned: "It’s the variety of minutes individuals spend speaking on a cellular that matter for heart health, with extra minutes that means larger danger.

"Years of use or using a hands-free set-up had no affect on the chance of creating hypertension."

However, the professor also suggested that chatting on the device may not affect the risk of developing hypertension as long as weekly calls are kept below 30 minutes.

The research team arrived at these findings by analysing more than 200,000 over 30s from the UK Biobank, which is a database that contains genetic and other health information on around half a million Britons.

Information on the use of mobiles to make and receive calls was gathered through a self-reported touchscreen questionnaire that included years of use, hours per week, and the use of a hands-free device or speakerphone.

The participants who used a phone at least once a week to make or receive calls were defined as mobile phone users in the study.

After adjusting the data for this criterion, around 88 percent of participants qualified as mobile phone users.

The research team tracked the participants for 12 years and also took into account factors like age, sex, smoking standing, blood pressure and more.

The results showed that weekly usage time of 30 to 59 minutes, one to three hours, four to six hours and more than six hours was associated with an eight, 13, 16 and 25 percent higher risk respectively.

This was compared to participants who spent less than five minutes per week making or receiving calls.

Furthermore, the likelihood of developing high blood pressure rose by 33 percent in those with a high genetic risk for the condition, who spent at least 30 minutes a week talking on a mobile.

The reason behind the blood pressure rise could come down to phones emitting low levels of radio frequency energy, which have been previously linked with spikes in blood pressure after short-term exposure, Professor Qin explained.

However, the results of previous studies on mobile phone use and hypertension were inconsistent.

Therefore, the professor explained that more research is required, “but until then it seems prudent to keep mobile phone calls to a minimum to preserve heart well being”.
