It looks like it may be time to find a new go-to cocktail when out at the club. The Centre for Addictions Research in Victoria, British Columbia examined 13 various studies conducted between 1981 and 2016 which studied the effects of mixing alcohol and energy drinks. It turns out that adding vodka to your Red Bull for a bit of spice is not exactly great for your body – but not for the reason you might expect.Rather than just sending your heart into overdrive when you indulge in this risky beverage, you're actually also more likely do something really stupid. The results published in the Journal of Studies on Drugs and Alcohol suggest that alcohol consumption in conjunction with energy drinks increases the risk of injury and falls when compared to alcohol alone. So, you actually end up getting a little more legless when mixing the two.When we drink alcohol by itself, we’re hit with an immediate moment of euphoria which, in turn, is followed by fatigue. When we add our little friend Red Bull to the equation, we get that great moment in the beginning with none of the fatigue at the end since the energy drink effectively masks it. So we stupidly continue drinking as we’ve essentially quieted the reasonable part of our brain that’s telling us “listen mate, I think we should probably call it quits here.”Audra Roemer, the author of the study, states that this cocktail may cause a less than desirable 'awake-drunk' state: Usually when you're drinking alcohol, you get tired and you go home...people may underestimate how intoxicated they are, end up staying out later, consume more alcohol, and engage in risky behaviour and more hazardous drinking practices.According to another study published in the science journal Plos One, this isn't the only risk factor when it comes to drinking caffeinated booze. In fact, researchers at Purdue University in Indiana found that consuming alcohol-mixed energy drinks causes long-term effects on the brain similar to those caused by taking cocaine. After conducting the experiment on mice who were given the alcohol-energy drink concoction, the scientists find increased locomotor activity – an effect which is similarly reached after consuming cocaine. Richard van Rijn, assistant professor at the university, explains.It seems the two substances together push them over a limit that causes changes in their behaviour and changes the neurochemistry in their brains. We are clearly seeing effects of the combined drinks that we would not see if drinking one or the other.Among the studies, three of them suggest that the choice of a Vodka-Redbull instead of just alcohol could depend on the personality of the drinker. Those with more impulsive personalities tend to lean more towards the combination of alcohol and energy drink. This thrill-seeking demeanour could also be linked to the higher instances of fights featuring consumers of the mixed drink.Sometimes it pays to listen to your body, after all. Maybe next time you go out for the night, stick to the drink by itself.
