Question: how many litres of water should you drink in a day nhs?
Answer: NHS Choices' page on Water and drinks says: Your body needs water or other fluids to work properly and to avoid dehydration. That's why it's important to drink enough fluids. In climates such as the UK's, we should drink about 1.2 litres (six to eight glasses) of fluid every day to stop us getting dehydrated.
