Coffee doesn’t just ward off dementia and single-handedly fuel college students everywhere: It’s also linked to a lower suicide rate, according to a large-scale study from the Harvard School of Public Health. Drinking two to four cups of coffee a day, or consuming the equivalent amount of caffeine via tea or chocolate, was linked to a whopping fifty percent decrease in subjects’ odds of committing suicide.
Researchers culled data from three massive pre-existing studies, combing information from more than 40,000 men and 150,000 women before announcing their findings in the World Journal of Biological Psychology. The study authors hypothesize that caffeine acts as a mild antidepressant as well as a stimulant, making it one helluva drug.
The usual caveats are involved: Don’t drink any more than those magical two to four cups; caffeine also makes you twitchy and not sleep; blah blah blah. But let’s be real: If this study isn’t enabling coffee hounds like nobody’s business, we don’t know what will. You’re welcome, baristas.
