ANN/THE STAR – Doctors are warning about the potential heart health risks linked to excessive caffeine consumption, cautioning that regularly drinking too much tea, coffee, or soft drinks could increase the risk of cardiovascular disease.
Speaking at a recent American College of Cardiology (ACC) conference in Delhi, researchers highlighted that consuming more than 400 milligrammes (mg) of caffeine daily (about four cups of coffee) may raise the risk even for healthy individuals.
“Chronic caffeine consumption can disturb the parasympathetic nervous system, leading to increased blood pressure and heart rate,” said Dr Nency Kagathara from the Department of Internal Medicine at Zydus Medical College and Hospital in Dahod, India.
The research team studied the effects of caffeine on heart health, focusing on people aged 18 to 45 who consumed coffee, tea, and fizzy drinks such as cola and energy drinks.
Their goal was to assess how chronic caffeine intake impacts heart rate recovery and blood pressure.
“Regular caffeine intake could increase the risk of hypertension and other cardiovascular events,” added Dr Kagathara.
The study found that individuals consuming 600mg or more of caffeine daily had significantly higher heart rates and blood pressure.
The highest caffeine intake was observed among women, individuals employed in business or management roles, and those living in urban areas.
Despite rising prices, the global demand for coffee and tea shows no sign of waning.
According to S&P Global Market Intelligence, global trade in coffee and tea is expected to grow, with compound annual growth rates of 1.1 per cent and 0.7 per cent, from 2023 to 2040.
While previous studies have suggested that coffee may help stave off cognitive decline, this new research highlights the importance of moderating caffeine consumption to avoid potential heart risks.
