But here's another question: Have you ever wondered how much coffee it would take to, well, kill you? It's macabre, we know, but don't tell us you've never given it thought. The good news: It's incredibly unlikely you'll come anywhere close.
Robert Glatter, MD, an emergency physician at Lenox Hill Hospital in New York City says that you would need to drink 50 to 100 consecutive cups of coffee to be lethal, USA Todayreports. However, consuming more than 500 milligrams of caffeine daily (there are about 95 milligrams in one cup) could lead to caffeine intoxication, which boasts symptoms like diarrhea, tremors, restlessness, and rapid heartbeat, though the amount varies from person to person. If you're sensitive to caffeine, even just one cup could give you jitters.
So how much coffee is safe? For the average person with a caffeine tolerance, Glatter says four cups will keep you in the green. This is music to our coffee-addicted ears, but know that cutting down leaves less room for issues (and more room for sleep).
