It's a widely believed notion that a person should drink at least two litres of water every day to stay healthy and hydrated. However, new research has busted the common myth.
Published in the journal Science, researchers looked at 5,604 people from across 23 different countries, aged between 8 days and 96 years.
As per researchers, eight glasses of water a day may be too much. Though it is not exactly harmful, it is also not needed in most circumstances.
The findings suggest that people only require about 1.5 to 1.8 litres of water a day which is lower than the two litres typically recommended.
