hydration

Proper hydration plays a crucial role in health and performance.

Water is the single largest nutrient in the body -- and one of the most important. Water is needed to regulate body temperature, keep skin moist, and transport oxygen and essential nutrients to cells. Yet, our bodies are also constantly losing water, as vapor in breath and as liquid from perspiration and urine, which must be replaced. A loss of just 1 – 2 percent of body water can put a strain on the cardiovascular system, and cause both health and performance to suffer.

Most people can get all the fluids they need from beverages and foods by simply letting thirst be their guide. However, children, athletes and older adults can be vulnerable to dehydration. Certain situations like extremes in climate and altitude can increase fluid losses. So it's important to understand hydration needs.
