A new study shows that talking on the phone for half an hour or longer (a week) increases the risk of high blood pressure
Talking on the phone for 30 minutes or more per week is associated with a 12% increase in the development of high blood pressureaccording to research that has just been published in the specialist journal “European Health Journal”, one of the publications of the European Society of Cardiology (ESC).
“It’s the number of minutes people spend talking that matters for heart health – the more they talk, the higher the risk,” said study author Xianhui Qin of Guangzhou Southern University in China. According to the researcher years of employment the “Hands-free devices” did not affect blood pressure, so this phenomenon needs further study to confirm the results and to determine exactly what the relationship is. It is estimated that three quarters of the world’s population aged 10 and over own a mobile phone.
Next to, Almost 1.3 billion adults between the ages of 30 and 79 suffer from high blood pressurewhich is considered a major risk factor for heart attack or stroke (stroke) and a leading cause of premature mortality worldwide.
Low level radio frequency
Cell phones emit low levels of radio frequency energy that have been linked to increases in blood pressure after short-term exposure. The results of previous studies on the use of mobile phones and blood pressure values have led to contradictory results.“Probably because they included SMS, calls, games and other activities,” says a statement from the ESC.
In this work, we specifically observed the Relationship between user’s calls and received and onset hypertension (they did not have this condition at the start of the study).
The researchers used UK Biobank data from more than 212,000 adults aged 37 to 73 without hypertension. Information on mobile phone use for making and receiving calls was analyzed using a questionnaire that recorded years of use, hours per week, and hands-free use.
The research team analyzed the Association between telephone use and the occurrence of high blood pressure accounting for variables that could confound results, such as age, gender, body mass index, race, family history of hypertension, education, tobacco use, baseline blood pressure levels, blood lipid levels, glucose, kidney function, and use of certain medications.
During the 12 years of follow-up, 7% of the participants (13,984 people) developed hypertension. Mobile users had a 7% higher risk compared to those who did not have this type of device. Those who spoke for half an hour or more had a slightly higher risk: 12% compared to those who spoke below this threshold. The results were similar in men and women.
Comparing the participants in more detail, they found that those who used their cell phones for less than five minutes a week and those who spent between half a minute and 59 minutes in the segment had 1-3 hours, 4-6 hours and more, the increased risk was 8%, 13%, 16%, and 25%, respectively. Years of use of the devices and “hands-free” use showed no signs of affecting blood pressure readings, the researchers write.
