hyperhydration
Too much water
Hyperhydration is excessive water intake or retention, resulting in diluted sodium levels in the blood.
Athletes sometimes hyperhydrate before endurance events, but severe cases can cause dangerous electrolyte imbalances: The marathon runner collapsed from hyperhydration.
The condition is the opposite of dehydration.
