There is a popular believe that mixing your alcoholic drinks causes awful hangovers. Is this true?? Lets have a look over some of the studies and evidences.
There are theories about the order in which to consume different liquors. One version suggests: “Wine before beer" and other says "Beer before wine." Whatever may be the case, after a multiple shots of drinks, it’s not always easy to remember. All of this asks the authencity of these sayings. There is only one question that pops in mind, Is there any evidence beyond the anecdotal that drinking wine followed by beer or vice versa makes hangovers worse?
A review of researches shows that the main symptoms of hangovers are dehydration, changes in the levels of hormones such as aldosterone and cortisol, and the toxic effects of alcohol itself. Additionally, there is evidence that the immune system is disrupted and that this could be the cause of the headache, the nausea and the fatigue.The first two main ingredients of a drink that affect the severity of a hangover is obvious. Higher is the alcohol content, and the faster you drink it, the worse is the hangover. This is however just an average. The same quantity of alcohol does not always lead to the same intensity of hangover. In a study of young Danes on holiday, almost a third of those who consumed at least 12 units of alcohol (roughly equivalent to four pints of lager or four 250ml glasses of wine) avoided hangovers.
Beyond the ethanol which initiates intoxication, the other key ingredient that affect hangovers are Congeners. Clear drinks such as white rum, vodka and gin tend to cause fewer and less severe hangovers because they contain relatively low levels of congeners. Perhaps those who mix their drinks are more likely to choose a dark-coloured drink containing higher levels of these substances, but again it isn't the mixing in itself that causes the problem.
So, the existing evidence suggests that hangovers can't be blamed on mixing drinks. It's probably down to the high congener count of the booze, or over-drinking. The quote rightfully goes here-
“To alcohol! The cause of... and solution to... all of life's problems”
