How much water do you really need?

Drink water. Drink more water. Drink water before and after you exercise. Sure, I'd heard all of that advice a million times but somehow, when I did my first distance triathlon in the heat of the competition, I forgot all about what I’d read in EatingWell Magazine’s article “Eat to Win” about what to eat and drink while you exercise. I mean, it was sweltering out there. It was a dry hot day on a sunny course. I was doing better than I ever expected. Felt great, in fact. So why stop at the water stops? Why let someone pass me?

Then, as I started to get toward the end of the race, my body slowed down. My mind slowed down. I felt lethargic. I lost five places in the last mile. But after I crossed the finish line, the really weird things started to happen: I couldn't find my bike. Or my car. Or my friends. In fact, I couldn't remember much, to the point where I forgot that I had finished the race and went to start the bike leg again. Finally, a friend said, "You're dehydrated," a fact confirmed later in the medical tent.

Ever since then, I've become religious about drinking water before, during and after exercise. (Should you drink bottled water or tap water?) Drinking water or other fluids (I like to drink flavored, low-cal drinks) consistently through your day allows the water to get to all the organs that need it—including your muscles and your brain—while you’re still resting. So, basically, you’re just setting yourself up to start off on the right foot when you are ready to exercise. (It’s important to eat too. Try these 3 on-the-go power breakfast recipes to fuel your day.)

The American Council on Exercise (ACE) suggests sipping an additional 17 to 20 ounces of water 2 hours before you exercise. But in 1 hour of exercise, the body can lose more than a quart of water—especially when it’s hot, like it was the day of my race. So it’s important to drink while you’re exercising too: 7 to 10 ounces every 10 to 20 minutes.

More isn’t better: Too much water can make you sick, a condition called hyponatremia where you essentially waterlog your system. So can going too long without replenishing electrolytes, such as sodium. So if you’re working out hard for more than 45 to 60 minutes, you’ll want to choose a sports drink or consume a food that contains some sodium (e.g., pretzels) with your water. (As for eating, check out these 4 natural fuel foods.)

And it’s not always easy to drink on the run, or the ride, so once you finish exercising you’ll want to replenish the fluids you’ve lost by drinking more. ACE suggests weighing yourself before, and after, exercise to see how much “water weight” you’ve lost. You should sip 16 to 24 ounces of fluids for every pound you’re lighter. No scale? Drink until your urine is a pale yellow.

Next time, I'm going to drink ahead.

    I wanted to comment on this thread. I had gastric bypass over a year ago. One of the things is push the fluids. But I couldn't push the amount requested of me in the beginning and LORD, it was alot. One thing I was taught with your body is that my physician gave this tip. The amount of water you should in take should be half your body weight in ounces. So if you weighed close to 300 pounds as I used to be, it should equal out to 150 ounces of water or fluids daily. I honestly can tell you that I couldn't do it over a year ago. But as I dropped the weight, it made the water in take easier. However i drank low cal flavored drinks, no carbonated drinks, they mess with your electralites and fill your stomach full of gases. One other key I can pass on to others is the fact of this bit of TMI(too much info) when you urinate you can tell if you haven't had enough water. The darker the urine means your not getting enough fliuds, the lighter the urine the more hydrated you are. I learned that from my physician as well. We all know we look so it's one of those unwritten things. Thought I'd pass that along. I can concure with the article however when I don't get enough fluids, how dizzy, tired and unfocused I can be. But after I make sure I get my in take I feel much much better.

    I started drinking a lot of water once I read an article about how if you don't drink enough water, your body holds onto the water b/c it needs it, but if you drink a lot often, your body lets go of the water, b/c it "knows it'll get more of the good stuff". But, today, I've drank about a gallon, a tiny bit less or a tiny bit more of water. I know, it's a lot and I usually do the same on a daily basis. Well, I haven't drank any more for about 2hrs and I am THIRSTY, lol. I think I may have that weird condition. j/k:P

    Good Idea ! And it's also shrewed suggestion to drink a cup of water after getting up in the morning and in the middle of afternoon( about 3 Pm ). The better intaking of water per day is about 1500ml, about 45-50 ounces for an adult.
