They carried out an experiment on 34 men and women who completed a number of mental tests twice – once after a breakfast of just a cereal bar and again after a cereal bar washed down with a bottle of water.

None had eaten or drunk anything overnight and all were asked how thirsty they were at the start of the experiment.
