According to a small research printed in the Journal of the American Heart Association, drinking thirty-two ounces of energy beverages manufactured by Monster Beverage Co. or just below 3 cans of Red Bull, in less than an hour pointed the risk of electrical disturbances in the human heart for as long as 4 hours later the beverages were drunk. Among the age group 18-24, 34 fit volunteers were aimlessly allocated to drink thirty-two of one of two commercially existing caffeinated energy beverages, or a placebo drink, on three distinct times.
Those two energy drinks had 304-320 milligrams of caffeine each thirty-two liquid ounces; as compare to roast packets of Starbucks Pike Place nearly 330 milligrams for sixteen ounces. Carbonated water was contained by placebo, with cherry and lime juice additive. The drinks were swallowed within a sixty-minute period, but no quicker as compare to sixteen-ounce saving every 30 minutes, so the participants were not persisting 2 beverages back to back. Electrocardiograms were taken by the researchers to measure electrical activity in the hearts of the topic, the QT interval, the span of time taken by it for the ventricles in the human heart to make to beat yet again.
The blood pressure of the subject was also noted by them. At the starting of the experiment, both the measurements were taken, and then each thirty minutes for 4 hours after the drink was drunk. The energy beverage gulped by the members had a higher QT interval at 4 hours as compared to the placebo drinkers, along with their blood pressure risen. Lifespan bullying heart arrhythmias can be caused by QT intervals, which are too long to too short, and failure of heart can be led by increased blood pressure, aneurysms and stroke due to the damage of the heart and the arteries. As this learning is small, additional research is required.
