First, let’s bust that old myth wide open. The “eight glasses a day” rule isn’t backed by solid science. It likely started from a 1945 recommendation that said we need about 2.5 liters of water daily.
But here’s the kicker: that same recommendation noted we get most of that from our food. Yes, your morning oatmeal and lunchtime apple are secretly hydrating you. So, do you really need to chug eight glasses? Probably not.
What Your Pee Tells You
Your body has a built-in water meter. It’s called urine. If it’s pale yellow or clear, you’re golden. If it’s dark like iced tea, you need to drink up—and maybe lay off the coffee.
But don’t aim for crystal-clear pee all day. That’s a sign you’re overdoing it, flushing out electrolytes like a confused plumber. Your kidneys don’t need a water park; they need a steady stream.
