"Years of use or employing a hands-free set-up had no influence on the likelihood of developing high blood pressure." The more time participants spent talking on the phone, the higher their risk of developing blood pressure.

Copy and pasted from European Society of Cardiology:

Almost three-quarters of the global population aged 10 and over own a mobile phone.2 Nearly 1.3 billion adults aged 30 to 79 years worldwide have high blood pressure (hypertension).3 Hypertension is a major risk factor for heart attack and stroke and a leading cause of premature death globally. Mobile phones emit low levels of radiofrequency energy, which has been linked with rises in blood pressure after short-term exposure. Results of previous studies on mobile phone use and blood pressure were inconsistent, potentially because they included calls, texts, gaming, and so on.
