I get that question a lot from my clients, and unfortunately, there isn’t a one-size-fits-all answer for everyone. Your water needs can depend on a lot of things: how active you are, the temperature outside, what foods you eat (certain foods are more hydrating/dehydrating than others), how much caffeine you drink, your stress levels, etc. The 8-glasses-of-water-a-day-rule is a good place to start, but you may need to add several more glasses on top of that, depending on your own individual needs.

Enter the Hydration Calculator, a very cool new online gadget that helps you calculate your daily water needs! Now, of course this isn’t fool-proof, since this doesn’t take into account things like the foods you eat and drink, if you’ve been in an airplane (very dehydrating), how stressed out at work you are, etc. But it’s a good place to start. And besides, who doesn’t love online calculating gadgets?! In addition to typing in your gender and weight,  I like that you can type in what activity you’ve done (running, spinning, walking, etc), how intensely you performed the exercise, and the temperature outside to come up with an approximate estimation of your water needs.

Take a look for yourself – and drink up!
