Doctors have warned that consumption of too large amounts of water can be dangerous for health, says Business Insider.

The publication explains that the kidneys can handle about 800 to 1,000 milliliters of water per hour. If this amount is exceeded, then problems arise, because it upsets the balance of sodium in the body. “Intoxication” water complicates the regulation of blood pressure, which can cause damage to the functions of the brain, coma and even death.

In addition, doctors note that over-hydration can be just as dangerous as dehydration, and people having problems with the kidneys, are most vulnerable.

The rate for an adult is three to four liters of water a day.
