New study challenges the idea that you need to drink 8 glasses of water a day.
Scientists have discovered the mechanism in the body that regulates how much we need to drink.
Scientists from the Monash University and University of Melbourne have identified the mechanism in the brain that stops people from drinking too much water, suggesting we should just drink when thirsty.
According to the scientists, we should just drink according to thirst rather than an elaborate schedule.
Drinking too much water can increase the risk of water intoxication or hyponatremia, when vital levels of sodium in the blood become abnormally low. It can lead to symptoms including lethargy and nausea to convulsions and coma.
