The theory that caffeine causes heart palpitations seems to have been disproven. A new study that was released stated that contrary to popular belief, caffeinated teas and coffees are not correlated with irregular heartbeats or any other heart issues. “[Researchers] examined 1,388 people, with an average age of 72, taking part in a larger heart study. About 60 percent said they drank some sort of caffeinated product every day. The team looked specifically at coffee, tea and chocolate and did not ask about super-caffeinated energy drinks. They measured instances of premature ventricular contractions and premature atrial contractions. They could not find any differences in instances of these heart disturbances, no matter how much coffee or tea or chocolate people had.” The researchers stressed that this study was only on specific caffeinated beverage effects on adults: children should not drink any caffeine and caffeinated powders have been proven to be exceedingly dangerous.
