Talking on a cell phone for more than 30 minutes per week may increase the risk of developing high blood pressure by 12%, according to a new study published in the European Heart Journal - Digital Health. The research, conducted by Professor Xianhui Qin of Southern Medical University in Guangzhou, China, used data from the UK Biobank and involved over 212,000 adults aged 37 to 73 years without hypertension at baseline.
The study found, mobile phone users had a 7% higher risk of hypertension than non-users, with the risk increasing based on the number of minutes spent talking on the phone each week. While previous studies on the topic have been inconsistent, this study focused specifically on the relationship between making and receiving phone calls and new-onset hypertension, using data on mobile phone use collected through a self-reported touchscreen questionnaire.
The study found, years of use and employing a hands-free set-up had no influence on the likelihood of developing high blood pressure. However, the risk of hypertension increased with the number of minutes spent on the phone each week, regardless of whether the phone was used for calls, texts, or gaming.
With nearly three-quarters of the global population aged 10 and over owning a mobile phone and hypertension affecting 1.3 billion adults aged 30 to 79 years worldwide, the study's findings have significant implications for public health. Mobile phones emit low levels of radiofrequency energy, which has been linked with rises in blood pressure after short-term exposure. Professor Qin noted, more research is needed to confirm the findings, but in the meantime, it may be prudent to keep mobile phone calls to a minimum to preserve heart health.
