At this point, we can safely confirm that booze is bad for the brain. The question on everyone’s mind, however, is how bad is it really? The vast majority of us leave binge drinking behind in college and our 20s. Surely knocking back a few drinks every week can’t really be that bad, right?
Well… a new study run by University of Pennsylvania researchers found that even light-to-moderate levels of alcohol consumption, like one drink a day, was associated with overall reductions in brain volume. That link only grew stronger as levels of alcohol intake grew.
And the study’s findings, published in Nature Communications, are only more alarming given that they encompass data from more than 36,000 adults—a sample size that’s far greater than earlier investigations probing the relationship between booze and brains.
