You’ve heard it: eight 8-ounce glasses a day. That’s about 64 ounces total. It’s a decent starting point, but it’s like saying “all cars need exactly one gallon of gas.” Nope. Your car—your body—is a wild, sweaty machine.
If you’re a 200-pound dude who works construction in July, you’ll need more. If you’re a 150-pound desk jockey who barely moves? Maybe less. The real magic number? Half your body weight in ounces as a baseline. So, a 180-pound man? Aim for 90 ounces daily. That’s about 11 cups.
But wait—there’s a plot twist. That baseline doesn’t include coffee, soda, or your post-gym thirst. Do not fear the diuretic myth. Caffeine isn’t going to drain you like a sinkhole. A cup of coffee still counts as mostly water. You’re welcome.
