Hydration

Are you thirsty?

If the answer is yes, your body may need more fluids and your body is giving you an important message. Proper hydration plays a crucial role in helping you stay healthy and perform your best. Water is the number one component of the human body, making up about 60% of your body weight. While this might sound like a lot, your body needs every drop and it is important to dehydrate. Fluids from the beverages you drink and the foods you eat are your body's primary source of water, which it needs to regulate body temperature, keep skin moist, and transport oxygen and other essential nutrients to your cells. Your body is constantly losing water — through your breath as you exhale, through your skin as perspiration, and through urine. This water must be replaced to maintain good health.

 
How can you be sure you are adequately hydrated?
As a general rule, most people get enough fluids from the foods and beverages they normally consume every day by simply letting thirst be their guide. However, there are certain situations that make paying closer attention to fluid intake important:
 
Age
Infants and young children are more vulnerable to the effects of dehydration than adults. That's why it's important to learn the signs of dehydration in children. Learn why low fluid intake is a problem and what you can do to help.
Physical Activity
Even mild dehydration can affect your workout performance. Learn what the experts say about fluid replacement during exercise. Paying attention to proper hydration can make the difference between winning the race and the feeling of defeat.
Climate & Altitude
Heat affects hydration - almost everyone knows that. But before you head out for that high-country vacation, you might want to learn how altitude affects your fluid needs.
