(ANN/THE STAR) – Doctors in India are raising concerns about the potential heart health risks associated with high levels of caffeine consumption, cautioning that drinking too many teas, coffees, or soft drinks could increase the likelihood of cardiovascular disease.
Speaking at a recent American College of Cardiology (ACC) conference in Delhi, researchers warned that consuming over 400mg of caffeine daily (equivalent to four cups of coffee) on a regular basis may elevate the risk for otherwise 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 (CAGR) of 1.1 per cent and 0.7 per cent respectively, 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.
