|About 250 ounces of water|
The old standby of 8 glasses of water a day would never work for me. By noon, I'd be wanting more. Others I know are perfectly happy to have a few sips throughout the day, and maybe a bottle with exercise. Can we both be right? How much water do we really need?
Runner's World has an article that gives a formula for a moderately active woman, using pounds. I'll plug my own stats in to get the results:
118 (body weight) x .31 = 36.58 ounces
Holy. Cow. Apparently this is enough water for me on rest days (when I don't run). Our diets supplement the rest of the water our body needs with water containing foods. I can guarantee that this would never work for me, but it's interesting to note. Maybe some of my less-thirsty friends have the right idea?
Keep in mind that runners/exercisers would need to add more water depending on how much they are sweating out. How much more? Because this is an individual thing, your scale is the best way to figure this out. Before you set out on your run, weigh yourself and write down the number. When you return, weigh yourself again and compare the two numbers. For every pound you lost, you need 16 ounces of water to rehydrate yourself.
Some interesting tidbits on hydration:
** As we get fitter, we sweat more. Obviously, we need to drink more in order to prevent dehydration.
**Hyponatremia is the other end of the spectrum, and means excessive water consumption, and low sodium levels in your blood. Women are more prone to this than men.
**In the 1960's, the Boston Marathon was run without ANY fluids along the route. It was believed that drinking water would cause stomach cramps.
How much water do you drink daily? Any extra during exercise?
I realize this might be abnormal, but I drink around 150 ounces per day. If I don't get the water, I survive, but I think I'm so used to it now after so many years of drinking a lot. During an hour long run, I'll drink anywhere from a few sips to a 20 oz bottle, depending on heat.
Do you buy bottled water? Use a special filter? or are you lucky enough to have clean water from the tap?
I bought a LOT of bottled water when we first moved, but now we refill them using the Brita Filter. This way I don't have to wash a ton of glasses, but it's much better for the environment!
