A new study by the Mayo Clinic shows that drinking one 16-ounce energy drink can significantly increase blood pressure as well as stress hormone responses.
The results raise concerns that consumption of energy drinks could, in turn, increase the risk of cardiovascular problems.
Previous studies showed that energy drinks lead to increased blood pressure in young people, but the new research sees the link between energy drinks and an increase in the stress hormone norepinephrine. This chemical could increase the risk of cardiac events.
The Mayo Clinic used 25 healthy participants for their study, who were asked to drink one 16-ounce energy drink and a placebo drink on two separate days. In addition to increases in blood pressure, norepinephrine levels went up by nearly 74 percent after the energy drink was consumed.
