Fluids and Fitness
Body fluid level is an important component of keeping it in top condition for best performance.
As a person exercises, the internal body temperature rises. That triggers the body to release internal fluid to the outside through millions of sweat glands and via heightened respiration. As the high temperature sweat evaporates off the skin, it takes heat with it, cooling the body down again.
That internal temperature regulatory system is vital to health, but losing too much fluid can also produce problems. High activity can cause a person to lose three quarts or more of fluid per hour. As the amount of fluid lost increases, performance decreases.
