Staying hydrated is crucial—just 1% dehydration can diminish athletic performance by as much as 15%. When we work hard, we sweat. And when we sweat, we lose water, sodium, and other electrolytes. To stay hydrated, our bodies need both. That’s why the most effective drink contains both. And, with 87% water plus sodium and potassium, milk delivers the perfect balance.
A DeGroote School of Medicine study at McMaster University showed that white milk rehydrates better than either sports drinks or water because it is a source of high quality protein, carbohydrates,calcium, and electrolytes. Milk also replaces the sodium you lose when you sweat, helping thebody retain fluids better.
A 2014 study published in the journal Applied Physiology, Nutrition and Metabolism repeated the findings, and also found that drinking plain water post workout can actually cause sodium levels to drop, increasing the risk of dehydration.
The right ratio of sodium and glucose in the intestine helps your body absorb fluids rapidly, returning you to the game faster.
