December, when work and home chores tend to increase. There may be many people here who want to get enthusiastic by drinking energy drinks.

However, it should be remembered that energy drinks have "side effects" behind the effect of "energy charging".


A study by the University of Bonn in Germany has shown that energy drinks high in caffeine can change heart rate. British media BBC News reports .

According to the media, a research team at the university asked 17 subjects to drink energy drinks and tested their heart function one hour later. Then, he found that the contraction movement of the heart became stronger after drinking the drink.


Until now, it was not clear how energy drinks affect health. But the study reveals that energy drinks that contain caffeine, about three times as much as coffee and cola, have a temporary effect on the contractile movements of the heart.

The effects of energy drinks on the contraction of the heart on daily life and the possible effects on people with heart disease are still unknown. However, the team warns that children and people with arrhythmias should avoid drinking energy drinks.
