Drinking 20 litres of water a day is highly unsafe. The human body needs, on average, between 2 to 4 litres of water a day depending on factors like activity level and climate. Consuming too much water can lead to water intoxication, also known as hyponatremia, where sodium levels in the bloodstream become dangerously low. This condition can lead to life-threatening health issues such as swelling of the brain, seizures, and coma. It's crucial to listen to your body and hydrate accordingly, rather than overconsuming.
