Energy drinks can change heartbeat
Consuming caffeinated energy drinks may detrimentally alter heart function, according to a new study.
Researchers from the University of Bonn in Germany studied the effects of energy drinks on 17 people using a heart imaging process. The participants consumed a drink with caffeine and a drink with taurine, a chemical commonly found in energy drinks—the levels of caffeine that were up to three times higher than those of coffee or soda.
The findings, presented at the annual meeting of the Radiological Society of North America, showed that the participants’ hearts were contracting harder than normal an hour after consuming the energy drinks.
The researchers said that they are uncertain about the long-term effects of consuming energy drinks. Children and people with an irregular heartbeat should avoid the drinks, they advised.
