According to Manuel J Castillo Garzón, Professor of Human Physiology from Spain's University of Granada, beer is actually better at rehydrating the body after exercise. When he gave some runners a half-pint of beer after a workout, it showed that beer helped quench their thirst and replenish calories better than those given water.

And that drunk, Garzón, isn't the only one backing the claims. Juan Antonio Corbalan, a (drunk) cardiologist who worked formerly with Real Madrid football players and Spain's national basketball team, said beer had the perfect profile for re-hydration after sport.
