You’d be hard-pressed to walk into a convenience store in the United States and not find so-called “energy drinks” lining the coolers.
Some even have their own specialty branded displays with bright colors and promises of increased performance, whether it be mental or physical.
While the science is still out regarding what’s exactly in these drinks and what the health effects are, some new research suggests chugging down a large energy drink could affect your circulatory system through your entire body.
A recent study — done on a tiny sample of medical students (who are typically younger), presented at a conference, and not published in a peer-reviewed journal — claims even just one energy drink could hurt a person’s blood vessel function.
Researchers at the McGovern Medical School at UTHealth in Houston found that an hour and a half after consuming a 24-ounce energy drink — larger than most available at corner stores across the United States — that 44 subjects had their blood vessels constrict to nearly half their size.
This is a problem because the smaller the vessels, the harder the heart has to pump to get blood to parts of the body, including the lungs, brain, and the heart itself.
The researchers say they believe that these effects may be related to the combination of ingredients in the energy drink: caffeine, taurine, sugar, and “herbals.”
