Asked in Health, Drinking Water
Can drinking too much water cause a problem for the body?
Drinking "too much" water CAN cause a serious health problem. Overdrinking water can lead to hyponatremia by diluting the sodium (salt) in your body. When this occurs, the brain takes on water in its cells and causes swelling in the brain, which is much like swelling in the brain from trauma-caused swelling of the brain. It can actually kill the person to whom it happens.
Why brain cells swell when the blood plasma is very dilute?
Osmosis is the movement of water from a High Water (Dilute Solution) to a Low Water (Strong Solution). If blood plasma becomes very dilute with water, when it travels to the brain the brain cells will swell because the are taking on too much water. This happens because the high concentration of water (in the blood) is moving to the lower concentration of water (brain cells) making the cells swell as they are taking on too much water.
