Neurocognitive accuracy of 2% less in speed and accuracy the next day doesn't sound like a strong incentive to not drink alcohol the night before.
Drinking whisky will result in a worse hangover than vodka, according to research by US scientists.
The reason might lie in the number of molecules called "congeners" which it contains compared to vodka, the Brown University team said. These include small amounts of chemicals such as acetone, acetaldehyde and tannins.
But the study also suggested that sticking to vodka all night rather than whisky would not improve your performance at work the next day. He said that the study also showed that workers in "safety-sensitive" roles could be impaired by drinking - long after the alcohol itself had disappeared from the bloodstream.
The overall performance of the drinkers — measured through neurocognitive tests using accuracy and speed over a prolonged period — was two per cent weaker following alcohol consumption than it would have been had they opted to remain sober — a small margin, but one that Rohsenow said could make all the difference in tense situations.
