There are times to ignore the averages and grab the nearest hose. If you’re sick with a fever, vomiting, or have diarrhea, you need more water than a weeping willow. Also, if you’re pregnant or breastfeeding, your body is essentially a water park for a tiny human. Up your intake by an extra cup or two.
And here’s a surprising fact: drinking too much water too fast can kill you. It’s called hyponatremia, and marathon runners die from it when they chug without replacing salt. So don’t panic-chug. Sip like a civilized creature. Your cells have feelings too.
Water Alternatives: The Good, The Bad, The Deceptive
Do you need fancy alkaline water? No. Your stomach acid has a pH of 1.5 to 3.5—it will laugh at any “alkaline” water you pour in. Do you need those electrolyte powders? Only if you just donated blood or ran through hell. Otherwise, you’re paying for fancy salt.
What about sparkling water? It’s fine. It counts. But don’t use it as a replacement for plain water if you have a sensitive stomach. And yes, coffee counts too. A moderate amount of caffeine doesn’t dehydrate you; it’s actually a net gain. So that double espresso you used to feel human? Put it in the hydration column. You’re welcome.
