This is your heart on an energy drink, and it’s contracting significantly faster than it was before you opened that can full of liquid stimulant.
So says a team of cardiac radiologists who wanted to figure out why energy drinks like Red Bull, Monster, 5-Hour Energy and Rockstar are sending tens of thousands of people to emergency rooms each year, including nearly 21,000 in the U.S. alone, according to a 2013 report from the Substance Abuse and Mental Health Services Administration.
A typical energy drink can have up to three times as much caffeine as coffee or soda, according to Dr. Jonas Dörner, a resident at the University of Bonn in Germany and member of the research team. High caffeine consumption can cause rapid heart rate, palpitations, a spike in blood pressure and even seizures or death, he said in a statement. Taurine is also a major ingredient in energy drinks, Dörner said.
