According to a study published in the European Heart Journal—Digital Health, mobile conversations for 30 minutes or more per week can increase the risk of high blood pressure by 12%. Mobile phones generate low levels of radiofrequency radiation, which has been linked to an increase in blood pressure after brief exposure.

At present, almost three-quarters of the worlds population aged 10 and above owns a mobile phone. Meanwhile, 1.3 billion people worldwide suffer from high blood pressure, or hypertension, particularly those aged 30 to 789. Hypertension is a key risk factor for heart attack and stroke, as well as a leading cause of early mortality worldwide.

In the study, a total of 2,12,046 adults between the ages of 37 and 73 were enrolled to determine the relationship between making and receiving phone calls and new-onset hypertension. The findings of the study showed that participants who spent 30-59 minutes per week making or receiving mobile phone calls had an 8% increased risk of developing hypertension in comparison to those who spent less than 5 minutes per week making or receiving mobile phone calls.

The study results also showed that those who spent 1-3 hours, 4-6 hours, and more than 6 hours making or receiving mobile phone calls were associated with a 13%, 16%, and 25% raised risk of high blood pressure, respectively. It was also observed that the likelihood of developing hypertension was highest in those with high genetic risk (33%), in comparison to those with low genetic risk who spent less than 30 minutes a week on the phone.
