Energy Drinks Make Your Heart Beat Abnormal

The average energy drink has between 70 mg and 90 mg of caffeine--a dangerous amount for your heart. In 2018, researchers from the University of Texas Health Science Center found that one energy drink can harm your arteries. The blood vessels narrow, which raises your risk of heart attack and stroke.

The largest study on energy drinks was in the Journal of the American Heart Association. In it, consumers experience electrical activity in their hearts. The arrhythmia, or abnormal heart rhythms, may encourage heart disease down the line.
