Diuretic effect of caffeine -

One of the reasons some of us try to limit the amount the coffee or tea we drink is that we've heard it can be dehydrating because it's a diuretic.

A diuretic is a substance that causes your body to produce urine, and it's been suggested caffeine can do this because it increases blood flow through your kidneys.

But if you regularly enjoy a few cups of coffee or tea a day, the moderate amount of caffeine they contain won't cause you to lose more fluid than you ingest, says dietitian and nutritionist Lisa Renn. A UK study of men who regularly drank coffee found no difference in hydration levels between those who drank four ml cups of coffee a day and those who drank the same amount of water.

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. Get our newsletter for the best of ABC Everyday each week.

Green tea in particular has been well-studied and shown to have health benefits. Tea can also be decaffeinated, though decaffeinated tea still contains a small amount of caffeine.

Its caffeine content is similar to that of decaf coffee. Herbal tea, on the other hand, is naturally caffeine-free. Some sports drinks contain caffeine. They also generally contain at least some electrolytes. However, sports drinks also tend to have too much sugar, more than is healthy, in order to make them taste better.

Similar to sports drinks, many sodas have caffeine added to them, around 22 mg per an average 8 oz serving, and many also come in sizes much larger than 8 oz. Unlike sports drinks, they do not usually contain electrolytes and have no health benefits. Soda and other sugar-sweetened beverages are linked to a variety of poor health outcomes, and this includes diet beverages with artificial sweeteners.

For those who enjoy the taste, consuming sugar-sweetened beverages in moderation once in a while is likely safe, but they are one of the least healthy sources of caffeine. A variety of other plants naturally contain small amounts of caffeine, including cocoa beans used to make chocolate , kola nuts, and yerba maté.

In general, they contain substantially less caffeine than coffee or black tea and are unlikely to cause caffeine dehydration. However, those who are very sensitive to caffeine may want to avoid them.

Studies on the effects of caffeine have sometimes produced contradictory results. Some people are extra sensitive to caffeine while others may not react at all. One study on voluntary caffeine consumption in rats identified three groups: high, medium, and low caffeine consumption.

As with rats, so too are people varied in their caffeine intake. If you enjoy drinking coffee, having up to cups of coffee per day appears to be safe and may even help your health. That said, pay attention to how you respond to it over time. Regular consumption can lead to addiction and desensitization.

Certain conditions can make negative side effects like caffeine dehydration more likely. Children and teenagers, women who are pregnant or breastfeeding, those who are sleep-deprived, and those who are taking certain prescription drugs or supplements may want to limit or avoid caffeine.

As always, seek medical advice if you are unsure how much is safe for you. Although caffeine has a mild diuretic effect, naturally caffeinated drinks like coffee and tea may have similar hydrating qualities to other hydrating beverages. One study found that the diuretic effect of caffeine was actually negated by exercise, demonstrating the potential safety of using caffeine prior to exercise.

The evidence of dehydration related to moderate caffeine consumption is fairly sparse. However, individuals with certain medical conditions, those who know they are very sensitive to caffeine, and anyone at risk of dehydration may want to exercise caution.

Caffeine dehydration can happen as a result of very high caffeine consumption. Moreover, caffeine is addictive , and addiction can lead to abuse. It can even lead to caffeine intoxication , a rare but potentially deadly condition.
