Drinking only one energy drink may in some cases increase the risk of heart attack within 90 minutes, according to a study conducted at Texas University in Houston.
Scientists have found that energy drinks tighten blood vessels, making circulation and limiting blood flow to vital organs, including the heart, difficult.
It is well known that energy drinks have a bad effect on the stomach, nervous system and can cause heart problems if consumed in large quantities, but now the list of adverse effects adds to the increased risk of metabolic syndrome.
During the research, scientists watched 44 students of healthy doctors in their twenties who are all non-smokers.
The aim of the study was to check the function of the endothelium, a layer of tissue on the inside of the blood vessels, as findings from earlier studies by the Sidars-Sainay Scientific Center at a homonymous Los Angeles hospital state that endothelial dysfunction is a significant indicator of increased risk of heart attack. arteries can not fully expand.
Houston experts checked the endothelium function of each respondent before consuming energy drinks and 90 minutes later. It turns out that after an hour and a half of drinking these drinks, the diameter of the blood vessels is half the size.
Scientists have combined this harmful effect with energy drinks, mainly caffeine, taurine and sugar.
An energy drink may contain, on average, 37 grams of sugar (9 tablespoons) and 80 milligrams of caffeine, which can cause increased secretion of adrenaline, leading to blood pressure leakage.
According to statistics in America, one-third of young people under the age of 17 regularly drink energy drinks, and studies in 2017 have shown that three cans (960 milliliters) can cause dizziness and arrhythmia in up to 50 per cent of adolescents.
