Having just ONE energy drink can narrow blood vessels in 90 minutes, study finds

"A lot of young kids use energy drinks when they exercise, a time when you need your arterial function to be at its top".
For the study, the team looked at 44 students from the McGovern Medical School at UTHealth.
Researchers from the USAF Medical Centre at Travis Air Force Base in California said previous year that people with high blood pressure, or heart conditions, might want to avoid the drinks. The research also hinted that regular consumption of such drinks will also affect the heart and nerve as well as can damage liver damage, tooth erosion and increase abdominal.
The participants were all in their 20s, non-smoking and classified as "healthy". Some researchers think adverse effects on the cardiovascular system may be associated with the effects the drinks have on endothelial function.
According to Cedars-Sinai Medical Center in Los Angeles, endothelial dysfunction has been shown to be an indicator of heart attacks because the arteries are unable to dilate fully. They tested the basic function of the endothelium blood vessel, and then checked her 90 minutes after the participants drank one energy drink 24 ounces. After consuming the energy drink, the blood vessel dilation was reduced, and experts revealed that it could restrict the blood flow and oxygen delivery.
Earlier this year it was revealed almost 70% of 10 to 17 year-olds in the United Kingdom consume energy drinks - more than anywhere else in Europe.
Caffeine can also cause blood vessels to contract and releases adrenaline, a hormone that can temporarily increase blood pressure.
According to the National Center for Complementary and Integrative Health, nearly one-third of American teens between 12 and 17 years old consume energy drinks regularly.
"As energy drinks are becoming more and more popular, it is important to study the effects of these drinks on those who frequently drink them and better determine what, if any, is a safe consumption pattern", authors noted.
According to the findings, consuming just one energy drink leads to notably diminished blood vessel capacity - an effect that lasts at least 90 minutes. "This could explain why there have been cases where kids have had a cardiac arrest after an energy drink", he said.
Plus, people often chug energy drinks so they get the full effect in one shot, and that might be risky, Higgins said."These drinks are not intended for children", Higgins warned.
