According to a British news agency, recent study from Southern Medical University (SWNS) in Guangzhou, China, has indicated that talking on a cell phone, even for a short period of time, might increase the risk of high blood pressure.
According to scientists, blood pressure is still a key cause of heart attacks and strokes.
The research results were published in the European Heart publication – Digital Health, a publication of the European Society of Cardiology, on May 5, 2023.
According to the study, people who spent 30 minutes per week conversing — even hands-free — on their smartphones were 12% more likely to develop hypertension.
It also revealed that spending six hours each week chatting on a cell phone increased the risk by 25%.
The SWNS team evaluated 212,000 persons from the U.K. Biobank, a database including genetic and other health information on half a million British people, according to the research. Those that were evaluated did not have hypertension at the start.
The sample size for the research was 212,046 people between the ages of 37 and 73 who did not have hypertension. It said that they were followed for an average of 12 years.
The study discovered that people who spoke on a mobile phone for 30 minutes or more each week had a 12% greater risk when compared to peers who used cell phones less regularly.
Participants with weekly usage times of 30 to 59 minutes, 1-3 hours, 4-6 hours, and beyond 6 hours had 8%, 13%, 16%, and 25% higher risks, according to the study.
The study went on to reveal that people with a high hereditary risk who spent at least 30 minutes a week conversing on a cell phone increased their chances of getting high blood pressure by 33%.
According to the study, cell phone users had a 7% greater risk than non-users.
“It’s the number of minutes people spend talking on a mobile that matters for heart health,” said lead author Professor Xianhui Qin, “with more minutes meaning greater risk.”
“Years of use or use of a hands-free setup had no effect on the risk of developing high blood pressure.”
Professor Qin stated that the study’s “findings suggest that talking on a mobile may not affect the risk of developing high blood pressure as long as weekly call time is kept under half an hour.”
“Mobile phones emit low levels of radiofrequency energy, which has been linked to blood pressure increases after brief exposure.”
“More research is needed to replicate the findings, but for the time being, it appears prudent to limit mobile phone calls to preserve heart health.”
