Nigella admits she's an aquaholic

According to the Daily Mail, Nigella Lawson has admitted to being an aquaholic and drinks in excess of 3 litres of water before bed. Could you also be drinking too much water?


She's been warned over health risks of her excessive water intake.

The Daily Mail reports that "She is a self-confessed ‘aquaholic’ who  has admitted in the past to drinking  three litres of water before going to sleep at night. [She has] been repeatedly warned about the health risks of her excessive water drinking by family doctor Peter Wheeler."

But what are the dangers of drinking too much water?

How much water do we need?

The human body contains up to 72% of water, or 45 litres in an average 70 kg man, and a bit less in an average woman. We don’t, however, lose all this water on a daily basis because our bodies are designed to maintain a balance of water and minerals in our blood and other body fluids.

Except in conditions where the water balance is impaired, such as heart failure and kidney malfunction, adults need 2500 to 3000 ml of liquid a day to stay healthy and prevent dehydration. If a standard glass/cup contains 250 ml, this translates to 10 to 12 glasses/cups of liquid i.e. water and other drinks, a day.
