Mixing alcohol with other substances is never really a good idea, and pairing it with energy drinks may be especially hazardous.
That might seem obvious, but the results of a new study published in Alcoholism: Clinical & Experimental Research provide some interesting insights into why. Cecile Marczinski, a psychologist at Northern Kentucky University, found that combining energy drinks such as Red Bull with vodka or other liquors effectively removes any built-in checks your body has for overindulging.
When you drink alcohol by itself, it initially induces a feeling of happiness — a comfortable buzz. But when you overindulge, your body knows it, and it starts to shut down; you start feeling tired, sleepy and more sedated than stimulated. “That’s your cue to go home to bed,” says Marczinski.
