Hydration

Water's Role in the Body

Water helps nearly every part of the human body function. Considering that our bodies are almost two-thirds water, understanding water's important role in the body can be a fountain of health. The following are just some of the things water does in the body:

* Brain is 75% water / Moderate dehydration can cause headaches and dizziness
* Water is required for expiration
* Regulates body temperature
* Carries nutrients and oxygen to all cells in the body
* Blood is 92% water
* Moistens oxygen for breathing
* Protects and cushions vital organs
* Helps to convert food into energy
* Helps body absorb nutrients
* Removes waste
* Bones are 22% water
* Muscles are 75% water
* Cushions joints

A person's body weight, and their activity level, determine the amount of water needed to maintain proper hydration. A good rule to follow is to drink at least eight, eight-ounce servings of water a day, adding more for each hour of activity.
