Our bodies are made up of 2/3 water. Water is used throughout our bodies as a solvent and an essential part of many metabolic processes. Without proper hydration, our bodies are not able to break down fats, proteins and sugars properly to be used as fuel for energy production.

Our bodies require between 1 to 7 liter of water per day, depending on the level of activity, temperature, humidity and what drugs we might be on. Warmer days with drier humidity require us to drink more water to stay hydrated. If our kidneys are functioning properly water is regulated properly within the body and is excreted, via urine and feces, through sweating and by exhaling water vapor in the breath.

Every time I go to the grocery store the "water aisle" seems to get bigger and bigger. There are many different types of bottle water and it wise to know what type of water you are drinking. Below you will find a list of the most common types of bottled water and what it means for the liquid inside.

- Club soda - tap water that has been filter, carbonated and flavored with bicarbonates, citrates, phosphates and other types of mineral salts.
- Distilled water - purified by evaporation, which removes minerals. The vapors are then recondensed into its liquid form.
- Drinking water - can be drawn from any approved source including municipal tap water, springs, rivers, reservoirs or wells. It is then filtered and disinfected and the mineral content may be adjusted.
- Mineral water - contains at least 500mg of minerals per liter. Minerals cannot be added to this water.

I recommend that a healthy person drinks half their body weight in ounces of water a day. Thus, if you weigh 160lbs, you would need to drink 80 ounces of water a day. If you are not use to drinking this much water, you will notice that your body will require you to urinate more often until your body adjusts to the new amount.
