Okay, so it’s not an open bar for bottomless espresso. Your coffee-based hydration comes with a few caveats. First, load it up with sugar and cream, and you’re adding calories and fat—not a hydration problem, but a pants-fitting problem later.
Second, if you’re new to coffee and your body isn’t used to caffeine, that diuretic effect can be a bit stronger. But give it a few days, and your body will be like, “Oh, this again? Fine, I’ll keep the water.” Your kidneys are forgiving little troopers.
Finally, listen to your gut—literally. If coffee makes your stomach angry, don’t rely on it for hydration. But for most of us, a cup of joe is a perfectly reasonable water substitute. It’s like water, but with a personality.
What About Your Morning Tea or Energy Drinks?
Same logic applies! Tea is basically flavored water with a hug. Herbal teas (like peppermint or chamomile) are even better—no caffeine, all hydration. Energy drinks? Well, those have other stuff (sugar, chemicals, neon colors), but they still contain water. Just don’t use them as your main water source unless you enjoy vibrating.
So go ahead, swap a glass of plain water for a cuppa now and then. Your body won’t send you a passive-aggressive email about it. I promise.
