                                According to a 2016 study published in *PLOS ONE*, cold and carbonated beverages can actually reduce thirst more effectively in water-deprived adults than plain water. This surprising fact reveals a crucial distinction: the sensation of a drink quenching thirst is distinct from its actual hydrating power. The question of why doesn't carbonated water quench thirst is therefore not a matter of hydration, but of perception.
