Here’s the good news: tea is almost all water. A cup of black or green tea is over 99% H₂O. That means every sip you take is a sip of hydration.
Your body doesn’t care if the water molecule came from a tap or a tea bag. It’s still water. Studies show that moderate caffeine intake doesn’t actually dehydrate you. The old myth that coffee and tea are diuretics? Mostly busted for normal consumption.
So, yes—you can absolutely count tea toward your daily fluid intake. The British have been proving this for centuries while surviving on endless cuppas.
The Caffeine Catch (It’s a Small One)
But wait—there’s a tiny catch. The caffeine in tea is a mild diuretic. That means it can make you pee a bit more.
However, the amount of water in the tea far outweighs what you lose. Think of it like this: every cup of tea gives you 200 ml of water, and then caffeine steals maybe 5 ml. You still win.
The real problem? Too much tea. Chugging ten cups of extra-strong black tea might tip the scales. But for a normal person with two to four cups a day? You’re golden.
