Myth #1: Coffee Dehydrates You
Everyone knows that coffee contains caffeine (unless it’s decaffeinated, of course), and it’s also common knowledge that caffeine is a diuretic—a substance that encourages urination and thus lowers the amount of fluid (mostly water) in your body. So, coffee is dehydrating, right?
Actually, no—not according to scientific research. A 2003 study concluded that consuming moderate amounts of coffee or tea (as part of a “normal lifestyle”) does not lead to any significant fluid imbalance, because most regular drinkers of caffeinated beverages develop “a profound tolerance” to the diuretic effects of the drug. Moreover, coffee and tea are mostly water, so drinkers are likely replacing most of the fluids they may lose.
The benefits of coffee are numerous, well-documented and supported by research. Coffee may be the most ubiquitous beverage in America, and it’s not just because it tastes amazing and it provides a valuable energy jolt; it’s also good for you. But how do the benefits of coffee relate to your relationships? What is it about coffee that keeps both your work life and your personal life on track?
