We can go for 50 days without food, but only two to three without water. Water is essential to the human body and we need about 2.5 litres of water a day.1 Most of this will come from fluids but some from solid or liquid food.

The total of 2.5 litres per day is a rough estimate and depends on several factors:

  • Age
  • Sex
  • Weight
  • Height
  • Level of physical activity
  • Temperature & climate
