A new study on alcohol and caffeine usage suggests that coffee not only won't sober you up if you're drunk, it can be dangerous by creating the illusion that it is doing some good. That assessment comes in a study by by Temple University that appears in the journal Behavioral Neuroscience, the BBC reports. In the study, mice given varying doses of alcohol and caffeine had to navigate a maze so as to avoid unpleasant stimuli, such as bright lights and loud noises.
The mice that got only alcohol seemed relaxed, but failed miserably, while those given only caffeine appeared more alert and fared better, although seemed to be uptight. But mice that consumed both alcohol and caffeine -- up to a human equivalent of eight cups of coffee -- appeared to be relatively alert and relaxed, but were still incompetent at avoiding nasty stimuli, the BBC says.
"The myth about coffee's sobering powers is particularly important to debunk because the co-use of caffeine and alcohol could actually lead to poor decisions with disastrous outcomes," says Thomas Gould, who conducted the research. He says those who consume both "may feel awake and competent enough to handle potentially harmful situations, such as driving while intoxicated or placing themselves in dangerous social situations."
