Hydration and Its Role in the Human Body
I never really thought about water the way I think about coffee. Coffee is obvious—you drink it, it jolts you awake, and it stains your teeth. Water, on the other hand, is quieter. You only notice it when you don’t have enough. Like the time I was hiking with only a tiny bottle, and halfway up the hill, my tongue felt like sandpaper. That’s when it hits you: the body actually runs on this stuff, not caffeine.
