"It is helpful to limit the duration of calls and calls to reduce the risk of cardiovascular diseases," Kumar said.

“Ensure good sleep and minimize psychological stress,” he added, while suggesting quitting smoking.

He said this citing a recent Chinese study, published in the Canadian Journal of Cardiology, which showed an increased association between mobile phone use and heart diseases such as stroke, coronary artery disease, atrial fibrillation and heart failure.

The number of mobile phone subscriptions has increased dramatically around the world in recent decades and surpassed 8.2 billion in 2020, according to data from the International Telecommunication Union.

At the same time, heart diseases have also increased significantly across the world, including India.

Data from the World Heart Federation (WHF) showed that deaths from cardiovascular diseases (CVD) increased globally from 12.1 million in 1990 to 20.5 million in 2021.

The study conducted by researchers at South China Medical University showed that weekly mobile phone use time was positively associated with the risk of cardiovascular disease.

The risk is "explained in part by lack of sleep, psychological distress, and neuroticism," the study showed.

Furthermore, the team observed that “mobile phones emit radiofrequency electromagnetic fields (RF-EMF), which could induce dysregulation of the hypothalamic-pituitary-adrenal axis, an inflammatory reaction and oxidative stress,” increasing the risk of CVD.

The study included 444,027 people with no history of CVD. After more than 12 years of follow-up, CVD risk was identified in 56,181 people (12.7 percent).

Compared with participants who used a mobile phone less than 1 hour per week, those who used a mobile phone more than 1 hour had a significantly increased risk of CVD.

The risk of CVD was also found to be higher in people with diabetes and current smokers.

"Smoking and diabetes increase the risk of cardiovascular diseases and therefore smokers should quit smoking and people with diabetes should keep their blood sugar level under control," Kumar said.
