It came as a shock to me too… But, scientists say that excessive usage of drinking water can ultimately result in serious effects and even death. It is known that our body fluids need various salts to maintain the flow. For example, blood cells have salts and they use this water to maintain concentration. In a situation where water enters the body in huge quantities, the body is no longer able to maintain its stability and the cells get filled up with water due to a process called osmosis. This halts the functioning of the cells. Same is the case for brain cells as well. in such a situation, water stops all the functions of the vital organs by this imbalance. If this state continues, the body goes into COMA and eventually leads to death. This situation is called water intoxication.
So, the next time you exercise and need to drink water bear this in mind and drink a more isotonic solution, so that it helps balance the salts in your body meanwhile quenching your thirst.
