Drinking too much water can cause brain damage and even death in extreme cases, say medical experts
Drinking a lot of water helps you pee more and flush out excess waste and water, but excess water can be dangerous because it causes sodium levels to become dangerously low.
While it may be counterintuitive to think that drinking too much water is bad for you, doctors say otherwise. Medical experts have cautioned that while the problems of dehydration are widely known, over-hydration can also lead to serious health complications and even death in some extreme cases, Daily Mail reports.
The kidneys can only process a liter of water an hour, although the average adult requires between 3-4 liters of water on a daily basis. The liquid is stored inside the body's cells with nowhere else to go. This causes them to swell and drags down sodium levels in the blood - a process known as water intoxication - ultimately making it difficult for the body to regulate blood pressure.
