This video explains how drinking too much water can create dangerous conditions in the body.
Drinking excessive water causes sodium and electrolytes in the body to go out of balance. Athletes are most at risk, since they often overhydrate in order to replace water lost from exercising, Healthline reported.
Danger caused by drinking too much water is rare, but it can lead to water intoxication or hyponatremia, a condition caused by low blood sodium. When electrolyte levels are drastically reduced from water intoxication, even death can occur, according to Healthline.
The appropriate amount of water to drink varies by individual and level of activity.
