Let’s be real—nobody wakes up excited to do math with their hydration. The coolest part of all this is that you don’t have to obsess. Your body has a built-in reminder: thirst. If your mouth feels like sandpaper, you need water. Period.
Another simple trick? Look at your pee. If it’s pale yellow like lemonade, you’re golden. If it’s dark like apple juice, grab a bottle. Your kidneys are better at math than you are!
So, the real answer to “How many bottles is 8 glasses?” is simple: it depends on the bottle, but about four is your magic number. Now go enjoy that water—and maybe a little less math.
