God, how we love it. Mornings just aren’t happening without coffee. In fact, some days, just the thought of caffeine coursing through our veins is all it takes to launch us out of bed. But is there such a thing as too much of a great thing? As in will too much coffee kill you?
It’s a serious question. Sadly, too much caffeine caused the death of a high school student from South Carolina who collapsed during class last month, according to the county coroner. Davis Allen Cripe died from a caffeine-induced cardiac event causing a probable arrhythmia. What happened exactly?
During an arrhythmia, or abnormal heart rhythm, the heart may not be able to pump enough blood to the body, and lack of blood flow affects the brain, heart and other organs. The teen consumed three caffeine-laced drinks: a cafe latte, large Diet Mountain Dew and an energy drink, all in a two-hour period.
So where does this tragic news leave adult java lovers? How much caffeine can you drink a day?
The experts say that most people can safely take in about 400 milligrams of caffeine daily or about 4 cups of coffee. Of course, the limit varies from person to person. It’s difficult to assign an exact amount for everyone because people can have different sensitivities or reactions to caffeine based on age, medical history, and tolerance. However, there is enough research available to make a recommendation based on an individual’s weight.

How Does Caffeine Kill You?
But how, exactly, can the world’s most popular drug kill?
Like other stimulants, caffeine raises blood pressure, boosts heart rate and temporarily shrinks blood vessels. In excess, the effects can be deadly by causing a heart attack, stroke or other cardio-vascular-related problem. Researchers think daily caffeine intake can increase the risk of coronary heart disease, but the results so far have been inconclusive.
It’s also important to realize that medical conditions can affect sensitivity to caffeine. If you have anxiety, panic disorder, heart arrhythmia, high blood pressure, diabetes, take medication or have any sort of medical condition, then you may tolerate less caffeine and should speak to a doctor.
