Anyone who drinks coffee knows it boost your energy levels and your mood, and even boost your workouts, but many are afraid to grab a cup to avoid dehydration.
However, multiple studies have now found that while caffeine is a diuretic, it is not dehydrating — as long as you don’t drink too much. It all comes down to math. Coffee is mostly water and can even be hydrating for some people. At the same time, it makes you more likely to urinate but only a relatively small amount.
While the amount of caffeine in two to four cups of coffee is an effective workout booster, if you’re worried that amount could leave you vulnerable, there’s good news. Research suggests you’d need to drink about 500 to 600 milligrams of caffeine, or about 5 to 6 cups per day, to tip the scales where you’re losing more water than you’re taking in. And that’s assuming you’re drinking no other fluids. So if you are a coffee drinker to this magnatude, remember to hydrate for insurance.
And remember, research also suggests that anywhere from two to five cups of coffee per day are have been linked with a reduction in cardiovascular disease, Parkinson’s, and certain cancers.
