Water: Not only good for you but necessary for a healthy life.

The human body is mostly water, so making sure I am drinking enough is important. I have heard that most people can’t tell the difference between being thirsty and being hungry. And since being even being mildly dehydrated can sap your energy and make you tired. We want to be careful, since we are exercising we sweat more then normal so we should be getting more water then the recommend amount.

Daily Water Requirements: Drink 50-75% of your body weight in ounces. Sedentary people: 50%; Active people: 75%

I will use 56% as my number. 307.5lbs * .56 = 172.2oz of water a day.

After doing the calculation I need 172.2 oz. of water a day. If we assume an average diet, about 20 percent of that water should come from the food I eat. So I need an additional 137.8 ounces of water daily. On average I am awake 16 hours a day, so I need to drink 8.61 oz. of water an hour to get the water that I need. This works out to be slightly more then a cup an hour that I need to drink.

After thinking about this and doing a little checking online, it seems that this formula is the closest to something that might work. It only works because there is a huge % range. The reason for this large % range is because there are so many things that might effect how much water you need. Here are some of those factors:

  • How active you are (How much you sweat)
  • What you eat (Some foods have more water in them then others)
  • Illnesses or health conditions (such as fever, vomiting and diarrhea, cause your body to lose additional fluids)
  • Environment (Hot or humid weather, dry air like in wintertime or the desert)
  • Pregnancy or breast-feeding (Women who are expecting or breast-feeding need additional fluids to stay hydrated)

So as you might guess with so many factors it might be impossible to get an exact amount. But if you look at the factors above and guesstimate the % we should be able to get close…
