Researchers in Spain have reached the surprising conclusion that beer may hydrate the body more effectively than water after a tough workout.

As reported in the current issue of Science magazine, researchers at Granada University in Spain tested 25 students who ran on a treadmill at a high temperature until they were exhausted. After the workout, half the subjects drank water while the other half were given two pints of lager.

The researchers found that the beer drinkers had “slightly better” hydration, motor skills and ability to concentrate. The scientists speculate that the sugar, salt and bubbles found in beer help the body to absorb fluids. Beer’s carbohydrates also replenish the calories you’ve burned off.

So next time you work out you may want to reach for the Budweiser rather than the Gatorade.
