Truth be told, we can drink whatever we want, whenever we want. But there is a certain stigma that comes with throwing back, say, a couple glasses of wine during lunch or an espresso late into the evening. “Do you want to be up all night?” is a common nag. But elsewhere in the world it doesn’t seem to be a concern. In countries like Italy, Spain and France, for example, late-night coffee culture is everywhere. But can they handle caffeine—the most consumed psychoactive drug—late at night better than anyone else? Can we, too, drink a lightly-roasted cup of coffee after dinner and sleep through the night?
Here, we seek to better understand the after hours coffee-drinking culture—and to figure out why some people can throw back espressos before going to sleep.
