It can, but you have to go wildly out of the norm for this to be so. Like, I have serious kidney issues, and I hate plain water. My nephrologist said me drinking 1-3 gallons of iced, and hot, tea per day is fine. The only time it becomes an issue is when you have have extremely concentrated black tea. Even then you would have to be drinking a lot of it, like a lot. He cautioned on tea mixes because those can add sodium, and of course not to use sugar, but that it would be little different than drinking water otherwise.
1-3 gallons seems insane to me. Sometimes when I get a little wild with Arizona my pee starts having crystals in it which is basically "Hey fuck off or stones are next." I can't imagine drinking a gallon+ a day and not being able to start a healing crystal shop with my dick.
I do a lot of hiking and shit. every day, almost. so i sweat a lot, like i can wring my hair and clothes out, a lot
also I use a simple black tea and some lemon, with nothing else. From what my nephrologist tells me, it sounds like you have some sort of issue processing it.
Yeah, I tried everything, and simply, it has to be flavored enough to taste other than water completely. However, my iced tea is black tea, with lemon, and that is it.
