Is Drinking Coffee Good for Creativity? Or Bad?

It's complicated.

From a piece in the New Yorker...

When we drink a caffeinated beverage, the caffeine quickly crosses the blood-brain barrier—an interface of sorts between the brain and the body’s circulatory system, designed to protect the central nervous system from chemicals in the blood that might harm it—and proceeds to block the activity of a substance called adenosine. Normally, a central function of adenosine is to inhibit the release of various chemicals into the brain, lowering energy levels and promoting sleep, among other regulatory bodily functions. When it’s blocked, we’re less likely to fall asleep on our desks or feel our focus drifting. According to a recent review of some hundred studies, caffeine has a number of distinct benefits. Chief among them are that it boosts energy and decreases fatigue; enhances physical, cognitive, and motor performance; and aids short-term memory, problem solving, decision making, and concentration. 

But all of that comes at a cost. Science is only beginning to unravel the full complexity behind different forms of creative accomplishment.
