There are so many types of tea to choose from when filling your cup. Each variety contains a different amount of caffeine, and the more caffeine, the less hydrating the tea.

As a result, it would be slightly more hydrating than black tea and slightly less so than herbal tea, decaf tea, or water. White Tea According to research , white tea contains about 32 to 37 mg of caffeine per 8-oz cup. That puts it somewhere in between black and green tea for its hydration abilities.

Would you believe that? So unless you're the type of person who would drink tea as much as that in a day, we think dehydration should be at the very back of your mind. This question makes sense, considering that coffee is a stronger source of caffeine.

Well, technically this is the case after they're brewed. However, just like tea, the likeliness of coffee to dehydrate you is just as low. With the amount of caffeine in it, it's more possible to produce mild diuretic effects like green tea and black tea.

It still depends on how much of it you consume. But remember kids, too much caffeine may lead to health issues. Always drink in moderation! If tea cannot dehydrate us, is it the other way around then?

It might surprise you, but caffeinated drinks happen to hydrate us just as well as water does. At least, this is what some scientists believe. Researchers conducted a study that showed consuming moderate amounts of caffeinated beverages, including tea, is as equally hydrating as H2o.

It involved 50 subjects who were heavy coffee drinkers that consumed ml of coffee or water in the same quantity each day for 3 whole straight days. That amount of coffee contains caffeine that is equivalent to 1, to 2, ml of tea. Results showed no difference in hydration between coffee and water.

Other studies made the same discoveries, finding no line between the capacity of caffeinated beverages and water in providing the number of fluids in our body.

This is a significant amount of proof that tea is indeed not dehydrating as others would think. Some of them also showed that in cases that teas do increase urine production, it doesn't really cause you to lose the same amount of fluids as you originally drank.

That's why the diuretic effects of the aforementioned caffeinated teas were only mild! Now that we understand that tea contains properties that can keep us hydrated, is it comparable to water? Can it steal the crown from water for the "best source of fluid in the body" title?

Some experts believe that tea is a better and HEALTHIER option than water. All that water does is rehydrate us and give us the fluids our body needs. However, tea does the exact same things along with having plenty of antioxidants and anti-inflammatory properties!

It can protect us from free radical damage that might lead to chronic illnesses like heart disease, cancer, and diabetes. It's also like coffee, except without the negative side effects of caffeine.

Drinking tea in amounts of two to three cups a day might also protect our teeth and strengthen our bones. Talk about hitting multiple birds with just one stone! If you drink tea or coffee, you are actually consuming a good amount of fluid along with a dose of caffeine.

Our bodies are made to absorb as much fluid as it needs and it just discards the others. So basically, tea actually keeps us hydrated. Both tea and coffee can be included in the count of 8 or more cups of water per day rule. Hope that solves the mystery!
