Why is caffeine diuretic

That means your body loses fluids and electrolytes like salt more rapidly than normal leading to a fluid volume deficit. The fluid in your cells is made of water and electrolytes that are essential for things like muscle movement and sending signals to your brain. However, caffeine intake and its short-term mild diuretic effects may make the signs of dehydration worse.

While diuretics can accelerate dehydration, there are many other ways you may become dehydrated. These include daily activities such as sleep, strenuous physical activity, and getting sick. If you develop dehydration from one of these main causes, consuming alcoholic beverages or caffeinated beverages like coffee — thanks to its diuretic effects — can compound the effects of dehydration.

Studies show moderate daily coffee intake under milligrams is unlikely to cause dehydration. If you regularly drink more caffeine than that, try swapping out a few cups of espresso with a lower-caffeine alternative like black tea. You can also try augmenting caffeine intake with DripDrop ORS, which provides a quick, easy and delicious way to remedy dehydration. DripDrop ORS comes in hot flavors such as spiced apple cider , hibiscus , and honey lemon ginger.

To stay on top of your hydration, you can use an ORS in place of one of your daily cups of coffee. For a refreshing alternative to iced coffee in the afternoon, you can enjoy DripDrop ORS flavors like berry and watermelon. For that, you need an oral rehydration solution like DripDrop ORS that can help you boost your electrolyte and water intake to fend off dehydration and the compounding effects of caffeine.

So, is coffee a diuretic? Meanwhile the volume of their urine was measured regularly. But the exact mechanism is still a matter of debate. Do caffeinated drinks affect the water intake we're told to be drinking every day?

But when you look at the studies of more realistic quantities of caffeine, the diuretic effect is not nearly so clear. A review of 10 studies by Lawrence Armstrong from the University of Connecticut concluded that caffeine is a mild diuretic at most , with 12 out of 15 comparisons showing that people urinated the same amount, regardless of whether the water they drank contained added caffeine or not.

As the review indicates, most studies give people pure caffeine added to water, rather than cups of actual tea or coffee as you might drink at home. Is there something about the combination of substances contained in coffee and tea that make the difference? Researchers measured the men's urine output over a hour period together with other hydration markers in their blood, and concluded moderate coffee intake provided similar hydrating qualities as water. While the study focused on the intake of coffee, those who drink tea can also take heart from the results because tea contains similar amounts of caffeine as coffee.

It's worth noting this study looked at men who regularly drank coffee. There's some suggestion coffee may have more of a diuretic effect on those who don't normally drink coffee because they haven't developed a tolerance to caffeine.

One of the reasons drinks containing caffeine — coffee, tea, cola and energy drinks — have been given such a bad rap over the years is because caffeine is a diuretic when consumed in large doses of more more than mg. When you lose too much sodium and water, you become dehydrated, and this can have an effect on a range of bodily functions — from temperature control to absorption of food.

However, the amount of caffeine you get in a cuppa is unlikely to have these effects and can actually contribute to your overall daily fluid intake. Men's bodies need around 2. Related Stories. Already a print subscriber? Go here to link your subscription.
