Daily goal

The default goal — 2 litres (68 fl oz) of drinks a day — is based on the adequate-intake values published by EFSA and the US IOM. How much water do you actually need?

This goal is above 4 litres (135 fl oz) a day — more than official recommendations suggest for most healthy adults. In heat or during long exercise it can be justified; either way, spread your drinking across the day.
