Is it possible to drink too much water?
As these athletes consume large amounts of water over the course of a race, blood plasma increases and dilutes the salt content of the blood. While this is happening, the athlete is also losing salt by sweating. Consequently, the amount of salt available to the body tissues decreases, and, over time, the loss interferes with brain, heart, and muscle function.
According to the experts at iVillage, consumption of large amounts of water is often associated with obsessive-compulsive behaviors. When a person consumes too much of this good thing, essential electrolytes in the blood stream become diluted and affect the control of the heart beat.
Healthy adults require approximately three quarts of fluid each day, half of which comes from food and half from beverages. Drinking 8 to 12 glasses a day should have your body working on all cylinders.
